Happy Holidays

November 29, 2017

Allow Extra Time for Epoxy Orders

As we approach the holiday season, please allow extra time for order processing and delivery,

Extend Epoxy Installation Season into Winter

Holidays mean temperatures are getting colder in many parts of the country . Our company started out as an installation company in Vermont. Summers are very short and winters are very long in Vermont. To stay a viable company, we had to figure ways of working through the winter.

Tenting and heating areas during the winter is time consuming and expensive. The solution is found in resin products that will set in low temperatures. The most durable and cost effective options of installation at cold temperatures is Epoxy and Methyl Methacrylate.

Cold Temperature Cure Resins can also be used as a super-fast setting Resinous Mortar or Coating at normal temperatures. Our Cold Temperature Cure Resins used at normal temperature give you quick turnaround time for small jobs, or larger jobs that require a short turn-around time.

Cold Temperatures Epoxies

Cold Temperature Cure Epoxy Resins allow installation to be done at low temperatures as low as 35°F., (although it sets a lot faster at 40°F) expanding your epoxy coating and epoxy flooring installation season. Epoxy.com Cold Temperature Cure Epoxy Resins can also be used in cold storage areas like food processing areas, where the temperature cannot be raised higher than 35° F or so. Normal cured epoxy typically requires 50°F or more.

Depending on how you mix the aggregate into the products below, they can be used as a mortar for overlays, or a grout for sealing between other hardened construction materials.

Commonly Used Cold Temperature epoxies

Product #1 Cold Temperature Cure Epoxy Coating is 100% solids and specially formulated coatings for cold temperature applications. Cold Temperature Epoxy Coating #1 is able to cure at temperatures as low as 35°F. It is has Zero (0) VOCs. Since it has no VOCs, it has no solvent so it meets the strictest possible standard for a low VOC coating. It is often used in coolers and food preparation areas that require constant low temperatures. Product #1 Cold Temperature Cure Epoxy Coating is also frequently used in room temperature applications to meet super-fast cure, limited shutdown needs.

Product #10 Cold Temperature Curing Epoxy Mortar Resin – This product has a low modulus of elasticity (flexibility) and is Low Viscosity. The low viscosity allows heavy loading of the right fillers. The heavy filler loading helps not only to save money, but helps to maintain better thermal coefficient with respect to concrete and steel. The low modulus of elasticity prevents it from being brittle making it less vulnerable to thermal coefficient differences. It also gives it better impact resistance.

Extending The Epoxy Install Season

October 17, 2017

Cold Temperature Epoxy

Installing Epoxy on Garage Floors in Cold Temperatures

Extend Epoxy Installation Season into Winter

It is that time of year again when I start getting  a lot of calls and emails about installing epoxy in cold temperatures. epoxy_color_chart_s

The best time to protect your floor is before it sees any salt at all. If you have a new garage floor now is the time to protect it.  It is still possible to do older floors but the more salt it sees the more difficult and expensive it can be.

The night temperatures are dropping this time of year. It is still possible to coat your garage floor before temperatures drop too low. Our cold temperature epoxies will cure with substrate temperatures as low as 35 degrees F, although it will set a lot faster at 40 degrees F.

Protecting your garage floors is especially  important in areas that will see salt from roads or ocean spray.  You will want to protect your garage from the ravaging effects of salt deterioration. Without protecting your floor salt will damage your garage floor and make for very expensive repairs later if it is not well protected.

It is not too late to protect your floor even in cold climates if you move quickly now.  Without this protection your garage floor will not be as nice come spring as it is now.  The damage that takes place is not only aesthetic but structural.

Existing Epoxy Seamless Floor Repair

June 29, 2017

Epoxy.com Materials have nearly 40 years of history with their seamless flooring products.  These high quality products seldom have to be repaired.  There have been a few times with Epoxy.com Products where the floor has been damaged in a fire, or a piece of equipment has been moved exposing an area that had not been done before.

IMG_1895

Picture of a Terrazzo Floor patched with an accent color.

The most difficult thing to do in repairing existing seamless floor is matching the color. The solution to this problem is a simple one: don’t try to match it, try to accent it.  Do this in a way that it looks like it is part of a design. This adds aesthetic appeal while creating an easy solution to the color matching issue.

Are you going to add additional seamless flooring next to the flooring to be patched?  If so use the accent color for the new area of flooring. That helps to tie all the colors back together.

For a complete list of seamless flooring epoxies please visit – www.epoxy.com. You can also email us, or call Epoxy.com  Technical Support Department at 352-533-2167.

Epoxy Injection of Structures Part 3

February 24, 2017

This is the third in a series on Infrastructure Repairs Using Epoxy. Part One is  Introduction to Epoxy Injection.  Part 2 is Crack Analysis Before Epoxy Injection

If your have not read that yet you may want to go back and read it before you proceed with reading this.

Port Setting

It is extremely important that if drilling to use the right tool. to set drill type ports use a vacuum swivel drill. That is a drill with vacuum attached swivel drill chuck and hollow a drill bit.

Concrete dust can be detrimental to the injection processes in several ways. Any dust remaining in the drill hole near a crack can combine with the very low viscosity injection resin. This thickens your resin turning it into a weak paste. This paste can slow or even block the resin flow. Drilling very tight crack with a solid drill forces dust into the crack. This seals the crack from resin flow. Do not allow shortcuts in the drilling procedures!  However, for most applications the surface port is the easiest and most effective method.Epoxy Injection Surface Port

Port Spacing

Determining the spacing of ports is done by a highly experience applicator. This spacing is a factor of the tightness of the crack and the depth of the concrete substrate. Spacing is normally between four (4) and eight (8) inches.

Port Setting and Sealing

Align ports directly over cracks. That allows injection resin to flow into the crack. Seal surface cracks. Sealing the exterior of cracks is done with Epoxy Gel type Bonder.

Testing The System

Test cracks that are ill defined, or if dust or debris is in the crack. This testing may be done by injecting water into the crack area.

Water left in the cracks will not effect the injection process or the curing of the Epoxy.com Injection Resin. Heavier injection resin forces the water out the cracks. Water injection helps clean the cracked areas. More important, is that it helps avoid the unexpected. This process of flushing the cracks is commonly skipped by more experience contractors, who can tell if there will be a flow of resin, by just looking at them. However, when in doubt water testing is a must.

If the cracks contain algae, chlorinated water containing copper sulfate is injected. After pumping this mixture is left over night. The next morning the crack is flushed by pumping fresh water, into it. This flushes it out before resin injection begins.

Efflorescence builds up on the bottom of a crack in a horizontal slab. Water in the crack extracting soluble calcium hydroxide is the cause. The water evaporates at the surface leaving the lime, which later reacts with the carbon dioxide in the air to form limestone. The inside of the crack, is frequently free of limestone and making it suitable for injection.

The following article is written with enough information about resin injection systems to help protect the Owner from the misuse or improper installation of an injection systems.   For more information contact me: Norm Lambert.

This is the second in a series on Infrastructure Repairs Using Epoxy. Part One was Introduction to Epoxy Injection.  If your have not read that yet you may want to go back and read it before you proceed with reading this.

Part 2: Crack Analysis Before Epoxy Injection

As with all repair and rehabilitation of concrete, the initial job analysis is by far the most important step. Epoxy Injection Resin will weld concrete cracks but, of course, will not repair the cause of the cracking.

Analyze each potential injection application to determine the exact cause or causes of the cracking. Correcting the cracking problem can be fairly simple, or may be difficult involving design changes.

Consult a structural engineer when design changes are necessary. Do this before starting the injection. Repairing cracks by Injection is effective after these design changes. Prevent future cracks by fixing the original cause of the cracking, when ever possible.

Parking garages are an example of cracking problem that require a structural engineering analysis.Epoxy.com Epoxy Inection Often inadequate design for expansion/contraction is the cause for parking garage structural cracking. Avoid weld injecting a crack if there are not enough expansion joints. Sometimes flexible overlays such as Epoxy.com System # 495 can be used to overcome this defect. This does not however encapsulate the rebar in a way that will totally stop the premature deterioration of the steel. Often times additional joints are needed, thus the analysis of cracking problems is critical.

Bridge decks and slab on grades can often be repaired with Epoxy.com Product #684LV crack healer and sealer and save some of the cost of doing epoxy injection.

Epoxy Structural Concrete and Wood Repair / Waterproofing

The following article is written with enough information about resin injection systems to help protect the Owner from the misuse or improper installation of an injection systems.   For more information contact me: Norm Lambert.

Part 1: Introduction to Epoxy Injection

Epoxy Concrete Injection Epoxy Wood Injection, epoxy crack repair

One of the most versatile, problem solving products available in epoxy systems today is Epoxy Injection Resin. Epoxy.com Epoxy Injection of a bridge abutmentStructural restoration of concrete by epoxy injection is very often the only alternative to complete replacement. It therefore results in large cost savings. Injection protects the rebar and stops water leakage.

Epoxy injection of concrete cracks has been used for decades. When properly installed it is still working as well as it did right after it was installed.

Epoxy Injection Resin is a system for welding cracks back together. This welding restores the original strength and loading originally designed into the concrete. Epoxy injection restores the structural qualities the concrete design intended. In other words under most conditions it makes the concrete as good as new. It creates an impervious seal to air, water, chemicals, debris, and other contamination.

Other waterproofing injection systems like urethane resin will seal the crack from water but will not repair the the member structurally.  That makes the structure member vulnerable to additional structural decay. This structural advantage that an epoxy injection repair gives, makes it the best choice for most situations. Epoxy or Urethane Injection discusses when to use epoxy and when to use urethane.

A crack, obviously, is a sign of failure caused by stresses, inadequate design, improper curing, etc. One of the dangers of a structural crack is the effect that it has on the reinforcing bar. The reinforcing represents one of the main structural values of the concrete.

Cracks left unprepared allow moisture, road salts and other contaminants to penetrate and attack the rebar. The rebar deteriorates, losing the structuEpoxy Injection of concreteral value. Loosing the entire structure is often the result.

Epoxy injection resin has two purposes. First, it effectively seals the crack to prevent the damaging moisture entry. Secondly, it monolithically welds the structure together. Most people assume that this welding of the structure is the most important result of the repair. Actually what is most important is the sealing.

The sealing properties of the injection prevents premature deterioration of the reinforcing. This can be of equal, or in some cases greater importance than the structural welding. It would theoretically always be desirable to get this welding effect.

Secondary Chemical Containment

February 7, 2017

You can easily build containment in the middle of an existing slab

Building a secondary containment structure in the middle of an existing facility is very common and effective way to protect the facility structurally as well as protect the environment.  It is very easy to do.  Here is how:

  1. Grind the area where the curb will go to bare concrete – www.epoxy.com/surfaceprep.aspx.
  2. Drill holes into the concrete and fasten #4 bar into the concrete with Epoxy.com Product #2006 – www.epoxy.com/2006.aspx – Gel Adhesive. Allow Epoxy to cure overnight.
  3. Form the area to receive concrete curb.
  4. Coat the floor area in the bottom of the forms to receive the concrete for the curb with Epoxy.com Product #2007 – https://www.epoxy.com/Epoxy_Fresh_Concrete_to_Hardened_Concrete_2007.aspx – Wet to dry concrete adhesive. Pour your concrete before the #2007 becomes tack free. That will make it as if the curb and the concrete floor had been poured at the same time.
    1. An alternate method to this is to install concrete brick around the area bonding in place with Product #2006. This will help to reduce waiting for the concrete to cure if you use the poured concrete method above.
  5. Allow the concrete to cure – www.epoxy.comsurfaceprep.aspx.
  6. Cove the inside of the containment curb with Epoxy.com Product #720 – https://www.epoxy.com/720.aspx – coving resin allow to cure overnight.

Epoxy River Simulation

November 16, 2016

How to Simulate a River Bed in Epoxy


A customer asks, “I recently saw what looks like a creek bed built out of epoxy with stones in it. How is this done in epoxy?”

Here are the steps to do it:

  1. Choose your stone. The stone that you choose can be uniform in size or a blend of stone sizes and shapes.  If bigger stone is going to be used, it is recommended that you use a blend of larger stone with smaller stone.  Variations in shape will also help to increase the amount of surface area holding the system together, making it stronger. Be sure the stone is clean and completely dry before attempting any of the steps below.
  2. Make a mock-up of the complete system below in a small box made out of plywood or similar material. This will verify everything from stone selection, to aesthetics, to stone durability. It is also gives you a chance to practice your procedure,and get additional phone tech support from us if required before you proceed with your project.
  3. Construct the recessed area that your river will “flow”. That could be a recessed area in a concrete floor, a wooded shadow box or some other “box” to hold your river. Be sure the box is watertight and that the surface is properly prepared before proceeding –www.epoxy.com/surfaceprep.aspx
  4. Prime the area created in step 3 with Epoxy.com Product #12 – www.epoxy.com/12.aspx at a rate of 250-300SF per gallon.  Allow to cure until hard to the touch, typically 6-8 hours
  5. After the Primer in Step 4 is hard to the touch and before 24 hours has passed, apply a coat of Epoxy.com Product #1 – http://www.epoxy.com/1.aspx – 100% solids General Purpose Epoxy Coating to the bottom of the box created in Step 3.  This will help to give you a consistent background color. Black helps give you the illusion of infinite depth.
    1. Optionally you can add a second coat of the #1 Pigmented Epoxy Coating to increase color intensity.
    2. On the other hand if the stone in Step 6 is so deep that you will not be able to see through it you can skip this step and proceed to step 6.
    3. Allow the epoxy in Step 5 to cure hard to the touch before proceeding, typically 10-12 hours.  Do not wait more than 24 hours before moving on to Step 6.
  6. Properly mix Epoxy.com Product #17 – www.epoxy.com/17.aspx – Epoxy Stone Adhesive Part A and Part B. Add your stone into the mixed stone adhesive.  The amount of stone that you will be able to add to it will vary depending on size and how clean the stone is.  100 lbs per 3 quart batch (2 QT “A” and 1 QT “B”) is a good starting point.  This ratio should be verified in a mockup before proceeding to this step. Mix in the stone until a uniform shine can be see on all the stone. Install this mix into your “box” at the desired thickness. Be sure to pack it in tightly and level to the desired surface.  Allow to harden overnight. Do not wait more than 24 hours before moving on to Step 7.
  7. Properly mix and pour Epoxy.com Product #214 – www.epoxy.com/214.aspx – Table Top and Casting Epoxy into the spaces between the rock in step 6. You typically will want to pour a minimum of 1/8 inch or not more than 1/2 inch at a time.  Take care to break any bubbles as you go early and often.  This is typically easy to do using a hair dryer and/or Isopropyl (rubbing alcohol mist). Allow each layer to harden and cool before adding another lift.  Never wait more than 24 hours in between coats and/or pours of epoxy.

When you complete this project it will look like a stone riverbed filled with \ water.  You can also experiment with other objects in your stone mix.  Contact Epoxy.com Technical Support with your questions: info@epoxy.com or 352-533-2167


Epoxy Sealing A Floor Drain

November 8, 2016

How to Seal Around an Existing Floor Drain with Epoxy


The Problem

A food processing facility owner writes, “I have a second floor production area that has a long stainless steel trench drain around the center of the room. We hose the area down with hot water, a crack is developing next to the drain that allows water to leak by into the room below.  The floor below my quarry tile is concrete.”

The Solution

  1. Remove tile around the drain.
  2. Remove the grout under the tile and clean back to clean solid concrete  www.epoxy.com/surfaceprep.aspx.
  3. Cut a V in the concrete next to the drain to increase the bonding surface to the drain. If you cannot cut a V chip away some of the concrete next to the drain.  In other words you are trying to cut away or break away the concrete around the drain to give more surface area for the epoxy to come in contact with. The additional thickness of epoxy (against the drain) gives you extra protection against leaks. The deeper you chip away next to the drain, the more bonding surface to seal against the drain. You need to be careful not to go all the way through the concrete. If you do you will most likely have to install a form around the drain with plywood or similar material (under the concrete)to hold up your epoxy when you go on to Step 7.
  4. Grind or otherwise abrasively clean the edges of the drain to remove the shine and roughen it up. It is not so important that you have deep scratches. It is necessary to totally remove all shine off the edge of the drain.
  5. Remove all dust, dirt and debris by vacuuming. If compressed air is used be sure it is oil free.
  6. Prime the edges of the drain with Epoxy.com Product #660 – http://epoxy.com/660.aspx  -Aluminum Filled Primer. Product #660 Universal Primer and Finish cures to a tack-free finish in 1-2 hours and can be recoated between 2 and 24 hours @ 75°F with 50% Relative humidity
  7. Mix a small batch of neat (just resin and hardener, not filler) Product #10 – www.epoxy.com/10.aspx. Use this mix to prime all areas that the patch (Step 8) will need to bond to. Apply this to all concrete surfaces as well as to the surfaces primed with  #660 Aluminum Filled Primer (Step 6).  You can either let the material in Step 7 set overnight and continue with the this step within 24 hours of priming,or you can move to the next step immediately. The purpose of this primer is to make sure there is a secure bond between the patch which will be a dry mix of epoxy and aggregate and the other surfaces that would otherwise be dry. This reinforces the bond line between the patch (in Step 8) and all surfaces it will need to bond to.
  8. Make a mortar of properly mixed Epoxy.com Product #10 and Epoxy.com Mortar Aggregate Product #82. Trowel the mix in to level the space between the drain and the remaining tile. Be sure to trowel the surface smooth. Allow to cure overnight.
  9. Do a squeegee coat of the properly mixed neat (no aggregate) Product #10 to seal the patch installed in Step 8.
  10. Allow to cure until it is hard to the touch, typically 10-12 hours at 75 degrees F.
  11. Within 24 hours apply a coat of Epoxy.com Product #2 – Chemical Resistant Epoxy Coating – www.epoxy.com/2.aspx.  Add optional but recommended Epoxy.com Anti-skid – https://www.epoxy.com/non-skid-additive-polycarbonate-aggregate.aspx  – to the #2 before applying it. Allow to cure hard to the touch.
  12. Repeat step 11.

Care of Epoxy Floors

November 1, 2016

Epoxy Flooring Systems and Coatings

Daily Maintenance of Seamless Flooring and Floor Coatings

  • Sweep the floors daily.epoxy_chip_flooring_263s
  • If abrasive particles  are present they should be removed by mopping with common household detergents and rinsed completely.  Be sure not to use the detergent at a concentration higher than that recommended by the manufacturer of the floor cleaning material.  Be sure to test any cleaner that you haven’t used before on a sample of the Seamless Flooring Material or Seamless Floor coating.  You may want to be sure to prepare these samples as you are installing the floor so they will be available to you at a later time.
  • Promptly remove grease, and other contaminants from the surface of the floor
  • Be sure to rinse off all chemical solutions that may attack the surface.

Weekly Maintenance of Seamless Flooring and Floor Coatings

Smooth Systems

All seamless flooring and floor coatings should be mopped on a regular bases with a neutral soap or detergent, and completely rinsed. Be sure not to use the detergent at a concentration higher than that recommended by the manufacturer of the floor cleaning material.

Be sure to test any cleaner that you haven’t used before on a sample of the Seamless Flooring Material or Seamless Floor coating.

Mop should be rinsed often. Synthetic mops tend to work better on textured surfaces than cotton mops. The water should be changed frequently as well. Smooth floors are easily cleaned this way. It may be necessary to give extra care to areas that are subject to heavy traffic, hard rubber wheels, and steel wheels that leave marks. In these situations you can use the methods used for textured floors for these more difficult to remove contamination.

Textured Systems

Textured systems may require the use of a stiff bristled brush or floor scrubber to reach to bottom of the anti-skid texture.  Severe problem areas can be treated as follows:

Grease Removal

Grease is typically removed by Tri-sodium phosphate (TSP) or other commonly available biodegradable cleaner. Contact Epoxy.comTechnical Support Department with your specific questions.

Removing Dairy Products

Dairy products should be removed immediately as they may cause staining on some types of seamless flooring and seamless floor coating systems.

Tire Marks Removal

Scrub the area(s) with a stiff bristled brush and using the same biodegradable floor cleaner that you are using to mop with.

Stubborn Dirt or Stain Removal

When you are trying to remove stubborn dirt or stains,allow the biodegradable cleaner to set in the area for a little while longer and do the work for you. Then completely rinse to area to remove the cleaner and the dirt.

Chemical Spills

You should always rinse strong chemicals as quickly as possible completely from the surface. Chemicals allowed to dry on the surface typically become more concentrated as they dry.  That may cause the chemical to get concentrated enough to stain or even attack the seamless floor or seamless floor coating.

Waxing and Polishing of Seamless Flooring and Seamless Floor Coatings

Epoxy.com Epoxy and Urethane Seamless Flooring and Seamless Floor Coating Systems are very shinny and so waxing or polishing are not necessary.  If a floor is very old, or has seen extremely high traffic this shine may dull.  If it does then you can wax or polish the floor with standard commercial products that are designed for that purpose. Better yet, if this happens, you may want to renew or refinish your system – see below.

Renewing and Refinishing Seamless Flooring and Seamless Floor Coating Systems

Epoxy.com Epoxy and Urethane Seamless Flooring and Seamless Floor Coating Systems are designed to withstand heavy traffic and wear.  However, if there is enough traffic and/or abuse to cause the system to loose its shine, or show visible signs of wear, you may wish to restore the floor by “re-glazing” it.  Before re-glazing a flooring system or coating system you need to do the following:

  • Remove all wax, oil, grease and other contaminants from the surface
  • Lightly sand to break the shine
  • Consult with Epoxy.com Technical Support Department for the proper material to re-glaze you floor.  Be sure to follow all directions for installing the re-glazing material.

When in doubt contact Epoxy.com Technical Support at: info@epoxy.com or call us at 352-533-2167. You can also visit our website 24 hours per day at www.epoxy.com


Chemical Resistant Epoxy Selection

October 20, 2016

Requirements for a Chemical Resistant Epoxy or Vinyl Ester


Our Epoxy and Vinyl Ester product lines has extensive uses in Chemical Containment
and Chemical Resistance projects. The kind of product and systems we recommend are
based on a number of factors.  First we need to know exactly what you are doing:

  1. Are you patching concrete that has been damaged already? If so what is the extent
    of the damage?
  2. Do you need a secondary containment coating? If so what kind of traffic (if any)
    will this area see? Many of our systems will handle very heavy traffic.
  3. Are there any cracks that need repairing? If so how many lineal feet of cracks
    are there, what is the average depth and what is the average width. Repairing the cracks
    is the first step in making your project water and chemical tight.
  4. Are you looking to grout tile? We have chemically resistant Epoxy Tile Grout that
    has excellent chemical resistance.
  5. Is there any petroleum oil saturated concrete in the area. If so we have a product
    for that too.
  6. Is there any moisture vapor that is being transmitted through the floor?  We
    have solutions for that so please bring that to our attention when you contact us.
  7. Is this in an area where Static Disruptive or Conductive materials are needed (typically
    only in an explosive environment or where delicate electronics must be protected
    from static discharge).
  8. Total square footage of area requiring Chemical
    Resistant Epoxy or Vinyl Ester.

Then we will need to know some specifics about the chemical you are trying to protect
against:

  1. What is the specific chemical (or chemicals) that you are trying to resist against?
  2. What is the specific concentration of the chemical (or chemicals)?
  3. What is the duration of the exposure, before it will be cleaned up (if ever)?
  4. Is the exposure at an elevated temperature? If so what is that temperature, and
    how long will the chemicals be at this elevated temperature

If you have this information when you contact us, we can quickly help you to decide
what chemical resistant system is best and most economical for you.

Here is some additional reading that might interest you.

Machine Shop Floors

October 14, 2016

A customer writes, “I have a machine shop floor. The concrete has had a lot of oil on it over the years.  I need an anti-skid floor that will be easy to clean and will hold up to cutting oils and anti-freeze and protect the environment.

We have done exactly what you are asking many times.  A mechanics shop floor typically is done the same way.  Here is how:

1.       Good surface prep – www.epoxy.com/surfaceprep.aspx

2.       Properly mix and apply 1 coat of Epoxy.com Product #201 – www.epoxy.com/201.aspx oil stop primer to all oil saturated or potentially oil saturated areas at a rate of 200-300 SF per gallon.  Allow this to harden and inspect for good bond (see “Checking the Bond” below.  If any areas are loose return to step 1. If everything is well bonded proceed to next step within 24 hours of  this step.

3.       Properly mix and apply 1 coat of Epoxy.com Product #899 – www.epoxy.com/899.aspx – applied at a rate of 250-300 SF per gallon.  Allow to cure hard and proceed to next step within 24 hours of this step.

4.       Properly mix (including optional but recommended anti-skid 4a below) and apply first coat of Epoxy.com Product #2  – www.epoxy.com/2.aspx  – at a rate of 160-200 SF per gallon per coat by brush or roller. Allow to cure hard and proceed to next step within 24 hours of this step.

a.       Mix optional but recommended Epoxy.com Anti-Skid – http://www.epoxy.com/non-skid-additive-polycarbonate-aggregate.aspx – to the #2 at a rate of 12-16 ounces per gallon of mixed epoxy.  Mix completely into the mixed A&B #2 before applying the #2

5.       Properly mix (including optional but recommended Anti-Skid – http://www.epoxy.com/non-skid-additive-polycarbonate-aggregate.aspx 5a below) and apply 2nd coat of Epoxy.com Product #2  – www.epoxy.com/2.aspx  – at a rate of 160-200 SF per gallon per coat by brush or roller. Allow to cure hard for 24 hours at 70 degrees F. for light traffic, 48 hours for light traffic.

a.       Mix optional but recommended Epoxy.com Anti-Skid to the #2 at a rate of 12-16 ounces per gallon of mixed epoxy.  Mix completely into the mixed A&B #2 before applying the #2

Checking The Bond

There are a number of ways to check the bond of a floor.  A simple way with Epoxy Flooring is to try to separate the epoxy from the concrete. That can be done with the corner of a putty knife or a screw driver.  If you can remove the coating cleanly from the concrete without pulling concrete it is likely that you have a bond problem.  If you cannot get it off or you must dig off concrete to get it off, you most likely have a good bond.


Uses For Epoxy Table Top Resin

September 19, 2016

Today we will discuss all the uses of Epoxy.com Product #214 Table Top Resin.

So many of you are now scratching your head, trying to figure out how I can devote an entire article to what to use our epoxy table top resin for.

Characteristics

Product #214 Water Clear Epoxy Casting – Tabletop Resin – Bar Top Resin is an all-purpose, low viscosity epoxy resin system for coating wood and concrete counter tops, tabletops, bar tops and similar applications. It has excellent clarity and color retention. Our clear casting resin and tabletop resin / bar top Epoxy has zero (0) VOC making it essentially odorless and can therefore be used in occupied areas. It de-bubbles and flattens a lot easier than similar materials.

Casting Resin

Our epoxy table top resin is frequently used as “casting resin”. It is poured into forms typically made out of silicone. The material is allowed to harden and then forms removed. This can be for very small parts or it can be used for very large parts.

Table Top Resin as Flooring

Product #214 Epoxy Table Top Resin can be used when a super flat floor is required. It is possible to get a floor as flat as water. This is important under certain types of machinery such as MRI machines and equipment used to product high precision parts for use in items like space satellites.

Other Uses

Product #214 Epoxy Table Top Resin can also be used to make tiles. After they cure they can be installed with conventional methods or with Product #225 Epoxy Tile Grout.

The epoxy table top resin that we sell has also been used for dance floors, stages, theme parks and homes to produce a floor to simulate water. Often times this is done with rocks and other objects in the epoxy to give the appearance of steam, a river, a lake, or the ocean. At the same time it allows a super flat finish that allows dancing, and all the things normally associated with a flat floor.

 

Advantages of Clear Table Top Resin #214

  • Low odor for use in occupied areas
  • Low viscosity – good wetting properties
  • Meets USDA standards for use in food handling applications
  • Glossy finish
  • Stain resistant
  • Zero (0) VOC – No VOC means it meets the toughest low VOC standards.

Fixing Floor Damage with Epoxy

September 6, 2016

Industrial and commercial floors take heavy abuse. The older the flooring the worse shape it is in. Conventional wisdom says that such a breakdown of the floor is inevitable. There are steps you can take to protect your floor before it gets damaged. Once the damage has happened there are steps you can take to permanently repair most damaged floors.

Floor joints, are the source of many industrial flooring problems. The purpose of these joints (in original construction) is to give the concrete a controlled place for the concrete crack as it shrinks. They sometimes are called expansion joints. In theory they will expand when the concrete gets hot.Indoors, where temperature is somewhat stable, most of their function of these joints has ended after 28 days or so of concrete. Concrete does most of it shrinking in the first 28 days.

wheel across empty  joint

A wheel across an empty Joint

The downside of these joints in the concrete is that it gives a place for the concrete to start chipping away. See the highlighted (in blue) corners in the illustration to the right. When wheels pass across the top it hammers the edge in the opposite side of traffic flow. This breaks off tiny pieces of concrete (again drawn in blue as a triangle at the edges of the concrete joint). The bigger the area chipped out earlier, the bigger and faster additional chipping happens. Time goes on and “pot holes”start to form in the concrete joint in direct proportion to the number of times wheels have hit a given spot.This can become a major trip and forklift hazard.

The best way to prevent this concrete damage is to fill the joints with Epoxy.com  – Product #11-100% Solids Flexible Epoxy Joint Filler for Saw Cut Joints. The #11 is semi-flexible so it still allows some joint movement but (unlike caulking) is firm enough to support the hard wheel as it passes over the joint, virtually

wheel across a filled joint

Wheel Supported by #11 as it passes over the joint.

eliminating the pounding and chipping effect on the sides of the joint. See in this diagram how the #11 supports the wheel as it passes over the joint.

For application on flat surfaces Epoxy Joint Filler for Saw-Cut Control Joints Product #11 can be poured or pumped from an Epoxy.com Binary Pumping Systems. In areas where cosmetics are important mask both sides of the substrate before applying the material.

If the areas are bigger you can use Epoxy.com Product #12  blended with silica sand to make a mortar to fill epoxy_joint_repairthe pothole, then re-cut your joint with a concrete saw as shown in the diagram here. The Product #12 can also be mixed with silica sand and used to repair areas in the center of a slab that might have started as a random crack or because of a chemical spill or due to impact damage.

If you need the epoxy mortar to set at a lower temperature and/or faster Epoxy.com Product #10 Epoxy Mortar Resin in fast or cold cure may be the best option.

Here is an outline of getting your flooring ready and some of the types of flooring we can offer you.

Seamless Epoxy Flooring Systems Explained

August 15, 2016

Epoxy.com offers many different types of seamless flooring. We offer so many kinds that sometimes it confuses people. The purpose of this article is to explain the differences, and to help you choose the right epoxy seamless flooring system for your application. In some cases the right seamless flooring system will not even be an epoxy. It may be polyurethane or Methyl Methacrylate (MMA).

Epoxy Floor Coatings

Epoxy coatings can be effective flooring systems. When choosing epoxy as a flooring system choose a 100% solids (zero VOC, hard durable coating. You also want a coating that is available in multiple colors. These floor coatings can last for decades, so you want to pick a color that you like. Properly installed you will be looking at this floor coating for a very long time. This kind of flooring system is available in the following options:

  1. Epoxy.com Product #1 – www.epoxy.com/1.htm – meets all the criteria above. It has good chemical resistance, and excellent cost to benefit ratio. Great for warehouses, in areas with high traffic and only modest chemical exposure.
  2. Epoxy.com Product #1ESD – www.epoxy.com/1esd.aspx. This is the same as product #1 above but has conductive filler in it. Depending on the primer you use under this system it can be conductive (100,000 – 1,000,000) ohms of resistance or Electro-Static Dissipative (ESD) which is 1,000,000 to 1, 000,000,000 ohms. Used in plants that produce explosive materials like ammunition, fireworks, flairs, or explosive solvents, and used in areas of sensitive electronics, like computer server buildings, avionics, electronics assembly and electronic production areas.
  3. Epoxy.com Product #2 – www.epoxy.com/2.aspx. This is similar to product #1 but with a much higher chemical resistance. This major increase in chemical resistance is offset by only a small increase in the cost of the #2 over the Product #1. The product #2 is well suited for applications like garages, machine shops, sewer tank floors, battery rooms, cooling towers, grooming shops, dog kennels and all areas where an economical chemical resistant coating is required.
  4. Epoxy.com Product #633 – www.epoxy.com/633.aspx – is a highly chemically resistant epoxy floor coating and flooring system. Like Product #1 and Product #2 is extremely durable. Product #633 is typically used in areas where containment of aggressive chemical is imperative. For example Product #633 will hold up to continuous exposure of 98% Sulfuric acid for a period of at least 6 months without loss of structural integrity. Great for secondary containment for a large number of chemicals.

     

All the systems above can go over many different types of substrates with the proper surface preparation. All of the products above are available in 17 colors and can be color matched for an additional cost. The systems above can be combined with various anti-skid materials or broadcast with silica broadcast aggregate to produce a thicker floor.

 

Chip Floor

Epoxy.com Chip Flooring – www.epoxy.com/chips.aspx – is the perfect blend of economy, durability, low maintenance, and gorgeous appearance. It uses a 100% solids pigmented epoxy base coat, a full broadcast of plastic chips, and two coats of chemical resistant clear glaze. The chemical resistant glaze also makes this easily the most non-yellow epoxy top coat available today. This easy to clean chip flooring system is best for high traffic areas where appearance, durability and low cost of ownership is a must. Chip Flooring is great for commercial and residential kitchens, bathrooms, showers, grooming shops, kennels, veterinary clinics, garage floors, show rooms, rest areas, and much more. This product can be installed with an integral cove base. Epoxy.com Chip Flooring can be installed by a contractor but easy enough to be installed by a home owner. Epoxy.com Chip Flooring can be installed in a residence but is rugged enough to be used in the most demanding commercial applications.

Quartz Flooring

Quartz Flooring Product #15 – www.epoxy.com/15.aspx has a long history of being durable, attractive and non-yellowing. I personally installed this product on high school bathroom floors in the mid 70s. These floors have held up to the test of time with little or no wear, little or no loss of shine and little to no yellowing even under the urinals. This is also available with an integral cove base

Solid Colored Flooring

These solid colored floors are based around self leveling, trowelable or double broadcast application techniques. These floors are sometimes called shop floor. They are made to be thick and extra durable under extremely harsh environments. They can be top coated with any of the systems above under coatings. This kind of flooring is available in 3 speeds of cure: normal, fast, and cold cure. Solid colored flooring is also available with an integral cove base.

Methyl Methacrylate (MMA) Flooring

The big advantage of MMA is speed of curing. Each coat of MMA will cure hard to the touch in 1-2 hours. This allows the next layer to be applied quickly and traffic to be returned to it quickly. You can even build a fast setting integral cove out of MMA resin.

I personally installed MMA on many floors with very tight schedules. One restaurant was only closed for breakfast. The project started with rotten plywood floors. At 10 PM the carpenters came in to work. They removed rotten floor and floor joists. They replaced the floor joists and the plywood. At 5 AM we went in with the flooring installation crew.  We primed the floor and sealed up the joints in the wood and the screw holes. At 6:30 AM we laid the floor. At 8 we put a glaze coating on the floor and by 10:30 the restaurant workers were on the floor prepping for lunch. The floor installation from start to traffic took just 5.5 hours.

Polyurethane Decking Systems

Polyurethane Decking – http://www.epoxy.com/elastomeric.aspx – is the system best used in areas where maximum flexibility is necessary. This is typically outdoors, waterproof applications like balconies.

Specialized Flooring

We have a number of systems that are specialized flooring like conductive and ESD (Electrostatic Dissipative) flooring – www.epoxy.com/conductive.aspx – and various hybrid systems. If your project does not seem to fit in the categories above email me at norm@epoxy.com or call us at 352-533-2167.

 

In conclusion we offer many types of seamless flooring systems, they can be used for commercial and residential applications. These systems are durable, economical, and easy to install even by homeowners. These seamless flooring systems may be made out of epoxy, polyurethane, or methyl Methacrylate (MMA). Seamless flooring systems are available in multicolored or solid colored. They range in chemical resistance from very good to resistant to aggressive chemicals. When in doubt what is right for your project send me an email at norm@epoxy.com or give me a call at 352-533-2167.


Patching Vinyl Ester Floors With Novolac

July 28, 2016

A customer writes:

“We have a dairy processing and packaging facility that was built circa 1994.  At the time of construction we chose to install a flooring system which was vinyl ester based with fiberglass mat.  The floor has held up quite well in areas where it had a good bond.  The failures we have seen are in areas that covered either an expansion joint or control joint in the concrete.  In these areas the flooring has delaminated from the concrete.  Where possible we have made a clean cut through the flooring to an area where we had a good bond and left the concrete exposed.  Other failure areas are around floor drains.  We have made repairs with quick curing epoxies in the past but these don’t seem to bond well to the existing vinyl ester flooring. 

“Having a manufacturing facility with only one down day limits our ability to make substantive repairs.  During a search for low or no VOC  flooring systems I you folks.”

I have personally made many thousands of square feet of floor repairs that sounds exactly like the issues and conditions that you are describing.

Here is what I did to permanently resolve the issue, at least in the patched areas.

  1. Cut back the edges of the delaminated areas back to a point where the vinyl ester is well attached.
  2. Prep the concrete under the failed area and the edges of the old material – epoxy.com/surfaceprep.aspx.
  3. Prime with Epoxy.com Product #12 – epoxy.com/12.aspx
  4. Install a trowel coat of Epoxy.com Product #630 – epoxy.com/633.aspx and
    1. Epoxy Mortar Blend aggregate #82 Mortar Blend Aggregate
    2. Allow to cure hard to the touch and cool.
  5. Glaze with a neat coat of Epoxy.com Product #633 with optional Anti-skid – http://epoxy.com/non-skid-additive-polycarbonate-aggregate.aspx

Epoxy Over Epoxy

June 28, 2016

A customer writes: “I installed your Product #1 All Purpose Epoxy Coating on our floor about 20 years ago.  The floor is not warn out or pealing.  It does have scratches where pallets with nails sticking out the bottom has scratched the surface. I want to change the color to our company color anyway, so I want to re-coat the whole floor. How do I proceed from here?”

You will want to sand the existing floor removing all the shine.  It sounds like there was quality installation and surface prep, since you have no lifting or pealing. If you should have any that is loose you need  to completely remove loose coating .  Solvent wipe with Xylene. Lets solvent dry and apply your epoxy normally.

CAUTION:  Epoxy doesn’t like sticking to epoxy unless you do your surface prep meticulously.  I always recommend doing a test patch to test your surface preparation before you proceed with doing the rest of the floor. This can be done by placing a small test patch or patches. Let them harden overnight and then try removing them with a putty knife, screw driver of similar method to insure it is well bonded.

For more information please contact Epoxy.com Technical Support Department by email at: info@epoxy.com or by phone 353-533-2167.


Are Epoxy.com 100% Solids Epoxy Low VOC

June 23, 2016

A user writes: “I have seen a number of your products that are on a list or marked with a tag that says Zero (0) VOCs.  When I look at the data sheet it says that the Epoxy.com product is 100% Solids, but does not say it is Zero (0) VOCs.”

Norm Lambert > Thank you for pointing that out.  You bring up an excellent question.  Epoxy.com Products that are 100% solids (100% active ingredients) do not contain solvent, that means they have no VOCs making them compliant with the toughest Low VOC Standards. I will start updating pages on the Epoxy.com to reflect that in the future.  Until then please rest assured that all Epoxy.com Products that are 100% solids have no VOCs in them.


Maintaining Epoxy Stone

May 17, 2016
Epoxy_Stone_Overlays

Product #17 Epoxy Stone Overlay, with mixed stone sizes

It is that time of year again. If you have Epoxy Stone Overlays you know it gives  beautiful natural look. The Epoxy Stone Overlay looks like wet shinny rock. It allows water to flow more naturally, giving you additional drainage in areas that you are walking where you feet might get wet if it is raining or near a water source like a pool.

As time goes by your stone will get less shinny.  This is not just an esthetic issue.  The

Epoxy stone overlays need to be reglazed from time to time. That is true about epoxy stone overlay systems available from us or from anyone else. In some parts of the country in the direct sunlight this could be every year. Other parts of the country with less sun might be 5 or more years. If you wait to long to reseal your stone it will start failing as the bond breaks down between the individual stones. The stones will then start becoming loose. If not resealed soon enough eventially the whole system will fail. Sealing at proper intervals with the right material is the only way to prevent this.

If you don’t want a system you need to maintain, we have other (non rock) systems that require little or no maintanance.

Resealing the Epoxy Stone Overlay.

Product #15 Chemical Resistant Epoxy Floor Resurfacing System is typically used for resealing epoxy bonded stone. Product #15 Chemical Resistant Resurfacing system oxidizes much slower than other epoxies, and usually last much longer than other epoxies used for reglazing epoxied stone pebbles. You don’t want to use other epoxies that oxidize excessively unless you are willing to reglaze 1.5 to 2 times more often than with Product #15.

The Product #15 Epoxy to reseal your stone not only adds shine back but actually reinforces the connections between the stone. Never use acrylic and other sealers commonly sold at big box stores to reseal your stone. These non-epoxy sealers add shine back to the stone, but doesn’t do anything to reinforce the bond between the individual stones. Worse yet unless the single component non-epoxy sealers have totally been warn away, they will act as a bond breaker preventing future epoxy resealing from getting to the surfaces they need to get to, in order to give you your original strenth back.


Epoxy Oil Stop Primer

May 13, 2016
Epoxy_oil_stop_primer

Oil Saturated Concrete

 

Oily contaminated concrete is very difficult to bond to, but it can be done with special care and Epoxy.com Product #201 Oil Stop Primer.  Plant floors, warehouse floors, commercial, and residential garage floors can all have this problem.  Here is a typical question that I get about oil contaminated floors:

“We were looking at your product because we have a floor in a maintenance garage that is pretty well soaked with oil.  A new tenant is going into that space so we know that there needs to be something to allow the new floor to stick and to stop the odors.”

Here is my typical response:

Is the oil saturation petroleum oil? If so you need to:

  1. Degrease the floor
  2. Mechanically clean the floor – www.epoxy.com/surfaceprep.aspx.
  3. Apply 1 coat of Epoxy.com Product #201 – www.epoxy.com/201.aspx – at a rate of 200-320 SF per gallon.
  4. Inspect for bond the next day. If bond fails remove the loose #201 and go back to step one.
  5. If bond is good check for oil on top of the primer.  If there is oil on top of the #201 and it is well bonded remove the oil with xylene or other effective degreaser.
  6. Coat with 2 coats of Epoxy.com Product #2 – www.epoxy.com/2.aspx.

I like the Product #2 for these applications because it is very resistant to petroleum oils. Depending on your specific application the material you use over the #201 can be a number of different flooring, coating systems or chemical resistant epoxy floor systems.

For more information, please visit our website at www.Epoxy.com, contact our technical support department at 352-533-2167 or email me at norm@epoxy.com for a specific recommendation.

 


Choosing Stone for Epoxy Stone

May 5, 2016

Epoxy_Stone_OverlaysBonding stone together with Product #17 – Epoxy Stone Adhesive is attractive and functional. It allows you to have the look of natural rock. This “natural rock” will let water pass through it just like its non-epoxied counterparts. It is however a good choice when you don’t want that stone to be moved, accidentally or on purpose.

This function is so nice that I am seeing projects where larger and larger stone is being utilized for the same reasons (above) as the small stone. There are a few shortcomings that should be avoided when bonding larger stones.

You want to make sure when selecting your stone that it is not too round. Round stone reduces the square inches of surfaces touching each other that are bonded together. That reduces the strength of the material, by reducing the square inches of bonding surface. If angular stone is used (as in the picture above) you increase the surface area touching each other and increase the strength.

If you want larger stones in the mix, I suggest you use a variety of smaller stone to fill in the large gaps between the bigger stone. If you combine a mixed gradation of stone that is also angular (not round) you can get an excellent compromise of strength and large stone beauty.

Which Novolac is Best?

March 14, 2016

epoxynovolac633-ht1I get asked which Novolac Epoxy is the best one? That isn’t a good question. A better question is which Epoxy Novolac is best for your specific job. To figure that out you must understand the difference.

There are 4 primary Novolac Epoxies and a brief description of each:

  1. Product #235 – Novolac Tile Grout a highly chemical resistant, industrial grade, Novolac epoxy grout for ceramic tile, quarry tile, brick pavers, and stone. Epoxy.com Product #235 Chemical Resistant Tile Grout and Adhesive is supplied in pre-packaged kits containing resin, hardener, and mineral fillers that produce a dense, uniform seal. Typical applications for Epoxy.com Product #235 Chemical Resistant Tile Grout and Adhesive require superior resistance to thermal shock, chemicals, and heavy traffic found in the harsh environments of dairies, bakeries,  meat packers, breweries, canneries, bottlers, distilleries, and pharmaceutical plants.
  2. Product #630 Novolac Coating/Mortar Binder – a 100% solids epoxy Novolac ideal for harsh chemical and solvent resistant applications. It is ideal for use as a troweled mortar, slurry binder, and coating for concrete and steel in extremely corrosive areas where resistance to 98% sulfuric acid or other strong caustics is needed. Product #630 Novolac Coating/Mortar Binder is ideal for use as a protective coating for concrete and steel in the extremely corrosive areas of chemical plants and pulp mills secondary containment areas, water and waste treatment, and gas and electric utilities. A conductive version Product #630 Conductive Chemical Resistant Conductive Flooring is also available.
  3. Product #632 Novolac Control Joint Filler  is a 100% solids flexible Novolac epoxy Chemical Resistant joint filler for saw-cut joints of concrete slabs on grade.
  4. Product #633 Novolac Coating is a 100% solids epoxy Novolac coating ideal for harsh chemical and solvent resistant applications. It is used in secondary containment, solvent storage, pump pads, trenches, and other high exposure areas. It is ideal for use as a protective coating for concrete and steel in the extremely corrosive areas of chemical plants and pulp mills secondary containment areas, water and waste treatment, and gas and electric utilities. Product #633 Novolac Coating is commonly used as a seal coat for Epoxy MORTAR SYSTEMS where chemical resistant performance is required.

A couple of the these are simple:

  1. If you are looking for a chemical resistant or high temperature resistant tile grout. Then you want Product #235.
  2. If you want a joint filler in a floor that needs to have high chemical resistance you want Product #632 Novolac Control Joint Filler.

Product #630 Novolac vs Product #633 Novolac

Product #630 Novolac vs Product #633 Novolac is where the differences become more refined. These two products are very similar to each other. In some cases it is possible that either product will work. Here are the differences:

Product #630 Novolac Epoxy

  • 630 is more flexible than #633 Novolac Epoxy
  • 630 Epoxy Novolac in clear stays clearer longer than #633
  • 630 makes an excellent slurry but still can be used as a coating

Product #633 Epoxy Novolac

  • 633 Novolac Epoxy is slightly more chemical resistant than Product #630
  • 633 Epoxy Novolac will resist higher temperatures than Product #630
  • 633 Is an excellent coating but can be used as a mortar as well.

Acid Etching Revisited

January 25, 2016

During my last blog on January 10, 2016 about “Surface Preparation When Installing Concrete” we discussed among other things preparation of concrete by acid etching. I want to revisit that now in a slightly less formal explanation about why it is not the best of the possible methods of doing surface preparation.

Acid etching does not remove most contamination from the concrete. It is necessary before you acid etch concrete to remove most typical type of contamination like oil, grease, paint, mastic, and a host of other things first.

Acid etching attacks the Portland Cement. The Portland cement is the “glue” that is holding your concrete together. So acid etching done incorrectly will do more damage than good. Even if you do it correctly your floor may not be as strong a substrate for epoxy (or anything else) than it would have been if you mechanically cleaned it.

If you are going to acid etch I suggest that you not only do it properly but follow it with abrasive cleaning, to remove the soft top part of your concrete that is damaged by the acid etching. When I was an installer of epoxy products I rarely if ever acid etched but instead did mechanical cleaning.

Here are some of the reasons acid etching may not be desirable for your job.

  1. Acid etching is a risk to safety. Acid can damage items at your jobsite and pose a risk of injury to the people in the area.
  2. Mechanical cleaning is better for the environment, no acid will find its way into the ecosystem.
  3. Mechanical cleaning allows quicker turnaround time, you don’t have to wait overnight for the substrate to dry.
  4. Mechanical cleaning gives you more consistently high quality substrate than acid etching does.

In summary, whenever you can use abrasive cleaning it is safer and better than acid etching.

Surface Preparation for Resin Systems

January 12, 2016

Surface Preparation Guide
For Concrete, Wood, and Metal Substrates


CONCRETE SUBSTRATES

I. GENERAL INFORMATION

Surface preparation is considered to be the most important step of any resinous flooring application. Improper surface preparation could turn what seems to be a simple process into a lengthy, difficult repair. The following conditions will dictate the type of surface preparation:

A. Concrete Placement
1. Slab-on-grade or on the ground

a. A 10 mil minimum vapor barrier is necessary to prevent moisture vapor transmission. An efficient puncture proof barrier is recommended.

b. Proper jointing will minimize cracking which could transmit through the resinous flooring system.

2. Elevated Slabs

a. Pan construction should be vented.

b. Metal deck construction should be properly jointed to minimize cracking.

B. Curing and Finishing Techniques
1. Curing compounds, if used, must be mechanically removed from the concrete surface prior to all resinous flooring applications.
2. Recommended techniques:

a. Wet cure

b. Light steel trowel finish to minimize laitance and provide hard
surface

C. Age of Concrete

Concrete must be a minimum of 28 days old for resinous flooring applications. Primers are now available which can be used on fresh (green) concrete on some installations. Contact the technical department for details.

D. Previous Contamination can affect the bond of the resinous flooring and must be removed. Types of contamination are:
1. Oil, grease, or food fats can usually be burned off with a flame gun or removed with a commercial degreasing compound or solvent. Epoxy.com Product #201 Oil Stop Primer is an important tool in dealing with petroleum oil contaminated concrete.
2. Curing compounds, sealers, and other laitance are best removed mechanically with:

a. vacuum shot-blasting

b. scarifying

c. sand blasting

E. Present Condition
1. Test for moisture: Coating system bond failures on slabs on grade and elevated/lightweight concrete caused by moisture vapor transmission are the industry’s largest single problem and result in extreme frustration from owners, clients, and contractors. Epoxy.com recommends testing for moisture vapor transmission. The recognized methods are:

a. ASTM-F-1869  Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride: The maximum allowed water/vapor transmission rate is 3 pounds per 1,000 square feet per 24 hours.

b. ASTM F-2170  Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using In Situ Probes: This test measures the  relative humidity in the slab below the surface. If taken over a period of time, it will show the rate of drying in the slab. The maximum relative humidity should be below 80%.

c. ASTM-D-4263  Plastic Sheet Test: This test gives an indication that moisture may be present.

2. Moisture related failures can be prevented through:

a. Placing new concrete over an efficient vapor barrier.

b. Testing for moisture vapor transmission as prescribed above prior to resinous flooring application.

c. Applying a moisture vapor transmission reduction system where moisture content is too high for successful resinous flooring applications. See Epoxy.com Product #830 Moisture Vapor Treatment for more details

3. A clean surface is necessary to establish a strong bond between the resinous flooring and concrete.
4. Resinous flooring systems are only as sound as the concrete they areapplied to. All unsound concrete should be repaired or replaced prior to resinous flooring applications. Consult your Epoxy.com Technical Service Department for specific information.
5. Resinous flooring materials should be applied to level concrete substrates. Grind or fill high and low spots prior to application.
6. Repair cracks prior to resinous flooring applications
F. Mechanical Prep vs. Acid Etching

Resinous flooring materials ideally bond to concrete with a rough, sand-paper finish. This finish can be achieved by either acid etching or mechanical methods. The choice of preparation is dictated by the factors above. Other factors which determine the type of preparation include:

1. Ecological restrictions involved with waste removal which could prohibit the use of acid etching and other chemical methods.
2. The type of resinous flooring material: It is recommended that concrete floors be acid etched prior to application of polyester and vinyl ester flooring systems.
G. Acid Etching

The following steps are recommended for acid etching:

1. Dilute commercial muriatic acid with water using 1 part acid by volume to 3 parts clean water by volume. Add the acid slowly taking care to avoid splashing. Workers should be protected with safety glasses, rubber gloves, and boots. If skin or eye contact occurs, rinse affected area thoroughly with clean water and follow Material Safety Data recommendations.
2. Sprinkle acid solution onto the entire surface in order to allow the acid to reach all areas of the concrete. Adequate coverage is
approximately 75 ft²/gallon of acid/water solution. Do not puddle and spread.
3. Scrub the acid solution into the concrete using a stiff bristle broom to remove loose concrete and laitancy.
4. Before rinsing, look for areas where bubbling did not occur. These areas have not been sufficiently cleaned and will require mechanical scarifying and additional acid etching.
5. When the acid solution has stopped bubbling (usually after approximately 15 minutes), rinse the floor thoroughly with water. Do not allow the floor to dry before rinsing because the salts formed by the acid reaction may cause problems with the adhesion and performance of the resinous flooring system. Test pH of the concrete surface to verify that the concrete tests alkaline.
6. Finally, the floor should be dry mopped to remove standing water and dirt remaining after the acid etching. Allow the floor to completely dry prior to the application of any resinous flooring system. Failures can occur in resinous flooring system applications due to moisture remaining
in the substrate.
H. Mechanical Preparation

Contamination and other foreign materials must be mechanically removed to ensure a satisfactory bond. All dust and debris must be thoroughly removed.

II. OLD CONCRETE

Old concrete surfaces must be structurally sound. Any unsound areas mustbe repaired prior to proceeding with the resinous installation. For
proper patching and repairing, use Epoxy.com Technical Service
Department. Remove existing paint, scale and loose concrete by rough
sanding, sandblasting, shot blasting, or grinding. In some cases where
plant conditions allow, a stripper may be used to remove excessive
build-up of paints or sealers.

Structurally sound concrete should be mechanically prepared to remove any contamination. Vacuum shot blasting is the best method for achieving
a good profile for bonding and should be used where possible. Before
installation of any Epoxy.com Product the surface must be examined for moisture vapor transmission using:

ASTM-F-1869 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride.

ASTM-F-2170 Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using In Situ Probes.

ASTM-D-4263 Standard Test Method for Indicating Moisture in Concrete by the Plastic Sheet Method. This test is only an indication and should not
be used to determine moisture migration.

Other ASTM Tests which are applicable to concrete preparation are:

ASTM-D-4258 Standard Practice for Surface Cleaning Concrete for Coating

ASTM-D-4259 Standard Practice for Abrading Concrete

ASTM-D-4260 Standard Practice for Acid Etching Concrete

ASTM-D-4261 Standard Practice for Surface Cleaning Concrete Unit Masonry for Coating

ASTM-D-4262 Standard Test Method for Ph of Chemically Cleaned or Etched Concrete Surfaces

ASTM-C-811 Standard Practice for Surface Preparation of Concrete for Application of Chemical Resistant Resin Monolithic Surfacing

III. NEW CONCRETE

New concrete must be well cured and dry prior to coating. Allow to cure a minimum of 28 days unless using green concrete primer. No curing
agents or sealing compounds should be used at any time prior to coating. A light steel trowel finish is recommended when finishing the concrete surface.

Any oil, grease, laitance, or other foreign material must be removed. Steam clean with a strong degreaser such as tri-sodium phosphate. Laitance and other foreign material are best removed by mechanical
methods such as vacuum blasting, scarification, or grinding.

All new concrete can be acid etched or mechanically prepared by vacuum shotblasting, sand blasting, scarifying, or grinding. Vacuum shot-blasting provides the cleanest environmentally safe area during
cleaning. It also provides a mechanically rough surface to achieve a
good bond.

When acid etching, use a 3 to 1 dilution of water to acid and follow directions printed above.

Before the installation of any Epoxy.com resinous system, the surface should be examined for moisture. Test for moisture vapor transmission using ASTM F-1869 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride. The maximum allowable rate is 3 pounds per 1,000 square feet per 24 hours.

Another procedure that helps determine slab dryness is ASTM-F-2170 Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using In Situ Probes. Maximum allowable R.H. for protimeter test is 80%.

WOOD SUBSTRATES

I. GENERAL INFORMATION

Resinous flooring must always be applied directly to exterior grade plywood with extended glue line INTERIOR GRADE PLYWOOD delaminates easily and SHOULD NOT BE USED
as it could result in a failure of the resinous flooring system. MARINE GRADE PLYWOOD contains moisture repellants which could cause a darkening of the resinous flooring system and SHOULD NOT BE USED. All plywood must be completely free of all waxes, varnishes, or other foreign materials.

A. Plywood used to cover existing wood floors

9. Seal all joints and fastener head holes with Epoxy.com Product #2005 – Semi-Flexible Epoxy Gel Adhesive.
10. Prime surface with appropriate primer prior to system application. Surface may require double priming due to porosity of plywood.
B. Plywood used for new construction (plywood is laid directly on the joist)
1.  Exterior grade plywood “C” plugged with an extended glue linemust be used.

All plywood must be completely free of all waxes, varnishes, or other
foreign materials.

2. Use Ring Shank or Wood Screws at six (6) inch centers around panel edges and support.
3. Stagger all panel joints, fill joints with Epoxy.com Epoxy.com Product #2005 For outdoor applications cover joints with fiberglass
cloth and the membrane system being used with the outdoor system.
4. Lightly sand the floor surface to insure proper adhesion of the resinous flooring system.
5. Remove all dust with a vacuum cleaner.
C. Applications with waterproofing:
1. After preparing the floor surface as prescribed above, caulk all joints with Epoxy.com Product #2005 for indoor systems. For outdoor systems use the membrane used with the Epoxy.com outdoor system.
2. Apply the waterproofing membrane as specified.

METAL SUBSTRATES

I. Preliminary Preparation
A. Metal substrates must be structurally sound prior to any resinous system being applied. For best results Sandblast to Commercial Blast (SSPC10 / NACE3) for non-immersion applications and Sandblast to near white metal -(SSPC10 / NACE2) for immersion applications.
B. Remove all foreign materials such as oil and grease with solvents or other degreasing compounds.
C. All scaling and rust must also be removed mechanically by sanding, sandblasting, or abrasion.
II. Treat the blasted/abraded surface with a phosphoric acid solution as
described below in order to prevent rust formation if the surface is
left exposed for some time prior to application of the resin system.
A. Always use a 10% solution of Phosphoric Acid.
B. Mix acid solution in either glass, plastic, or earthen containers (never use metal containers), by adding Phosphoric Acid to water. NEVER VICE-VERSA due to heating or splashing which may occur.
Workers should be protected with safety glasses, rubber gloves, and boots. If skin or eye contact occurs, rinse affected area thoroughly with clean water and follow Material Safety Data recommendations.
C. Apply phosphoric acid solution by either paint brush or rubber squeegee and allow metal surface to AIR DRY.

DO NOT FLUSH METAL SURFACE WITH WATER.

III. Protect surface from contamination until the primer is applied.
IV. Wipe metal surface with MEK solvent immediately before primer
application.

Can I Install Epoxy over Ceramic Tile?

September 21, 2015

I have seen tiles that have been prepared in the lab environment that have epoxy well bonded to it. Doing it in under laboratory conditions and doing it in the field is two different things. In all the over 35 years I have been in the business I cannot point you at a single success story where epoxy was installed over tile.

My company started off as an installation company about 35 years ago.  When we were a young installation company we made build a sizable business by going around behind all of our competitors that were installing epoxy over tile, and redoing their failed work. That is why I typically I recommend against going over ceramic tile with epoxy.

Surface Preparation Requirements

Bonding to tile requires either intense physical abrasion like sandblasting or etching with phosphoric acid to remove the glaze.  If you etch with acid it usually eats up the grout.  Acid may, and more likely than not will, get under the tile and loosen it.

The heat and vibration of the sandblasting tends to loosen tile. Sandblasting will damage the grout. Best case situation the tile will require regrouting.

After all that, a single tile comes loose, or a single piece of old grout comes loose, and you have failed your objective.

Alternatives

Many people like the looks of tile. They don’t like the way tile grout leaks and is hard to maintain. For them I recommend that you remove the grout and regrout it with Epoxy.com Product #225 – www.epoxy.com/225.aspx. Product #225 is a 100% solids water cleanable epoxy that is waterproof grout. This eliminates most leaks and grout maintenance issues.

Thos of you that don’t like the looks of the tile, I recommend removing the tile.  Get down to a sound substrate.  And then proceed. – www.epoxy.com/surfaceprep.htm.

Apply Epoxy.com Product #1W – www.epoxy.com/1W.aspx to the walls. Product #1W is a 100% solids waterproof coating that leaves a ceramic like finish. Product #1W applies much easier than most 100% solids epoxy. It has superior durability and abrasion resistance.

For floors (after the tile is removed) I would level with Epoxy.com Product #12 mortar – www.epoxy.com/12.aspx and then install Epoxy.com Chip Flooring – www.epoxy.com/chips.aspx. Heavy traffic on floors often makes the use of decorative flooring products impossible. Product #315 Seamless Polymeric Multi-Colored Flake Chip Floor Resurfacing System makes this possible. The #315 Chip System creates a beautiful, durable, and affordable floor that is easy to apply by both professionals and do-it-yourself enthusiasts.

Selecting the Right Floor for a Mechanical Room

July 27, 2015

Mechanical Room Floors are very unique in their use and conditions. You have to consider the installation environment and the function of the floor. Our Mechanical Room Floor will protect the concrete, and contain any liquids that spill.

Systems used in mechanical rooms should be zero VOC. You do not want solvent evaporating from your material. Evaporated solvent could be picked up by your air handling unit sending it through your building. The best way to prevent this is with a VOC free 100% solids resin system. A resin system that is 100% solids has no solvent (or water) in it. It also means when you spread a gallon of material on your floor after it hardens you still have a gallon of material. With water-based and solvent based materials you lose half the material to evaporation.

Mechanical rooms should be chemical resistant. Typically they are top coated with Epoxy.com Product #2 Chemical Resistant Epoxy – www.epoxy.com/2.aspx. If it is a chemical feed room you can supply a list of chemicals and concentrations to the technical support department so you can make sure the #2 is chemical resistant enough.

The systems used for mechanical rooms are impact resistant. The limiting factor is the strength of the concrete substrate. Properly installed the epoxy will stay bonded to the concrete. The only way the epoxy can chip is if you chip the concrete from underneath the epoxy. You can install a thicker epoxy floor for an additional cost if you think you need still additional protection.

The systems recommend for mechanical rooms are highly abrasion resistant and will easily handle traffic up to heavy fork lift traffic. The system can be made even thicker if you have an unusual amount of abusive traffic.

When the mechanical room is over a finished space, it is suggested that a crack isolation membrane be integrated into the system. This can be done with Product #32 Epoxy Membrane System. The advantage of #32 Epoxy Membrane Resin as part of the system is 100% solids and has zero VOCs.

If the mechanical room is shut down and you can handle solvent and want something still more flexible you can use Epoxy.com Product #459 a two component, high solids, elastomeric urethane instead of or in addition to the Product #32 Epoxy Membrane above. Product #459 exhibits excellent elongation properties along with high tensile strength and tear resistance to make it an ideal crack resistant membrane for use under Product #2 and all of our other epoxy mechanical room floor coatings.

One of the primary reasons you need a mechanical room floor over finished space below is to waterproof it. The above methods accomplish the waterproofing in the center of the floor. The edges of the floor can be protective with a coving material up the wall and around pipe penetrations. That can be accomplished with Product #720 Epoxy Coving Resin System which can be used to install an integral cove base for all of our epoxy based mechanical room flooring and most of our other epoxy flooring and coating systems. This provides seamless wall to floor protection.

For more information on seamless water and chemical resistant mechanical room flooring, contact Epoxy.com Technical Support Department at 352-533-2167, or email me at norm@epoxy.com.

Surface preparation is considered to be the most important step of any resinous flooring application. Improper surface preparation could turn what seems to be a simple process into a lengthy, difficult repair. The following conditions will dictate the type of surface preparation:

A. Concrete Placement
1. Slab-on-grade or on the ground

a. A 10 mil minimum vapor barrier is necessary to prevent moisture vapor transmission. An efficient puncture proof barrier is recommended.

b. Proper jointing will minimize cracking which could transmit through the resinous flooring system.

2. Elevated Slabs

a. Pan construction should be vented.

b. Metal deck construction should be properly jointed to minimize cracking.

B. Curing and Finishing Techniques
1. Curing compounds, if used, must be mechanically removed from the concrete surface prior to all resinous flooring applications.
2. Recommended techniques:

a. Wet cure

b. Light steel trowel finish to minimize laitance and provide hard surface

C. Age of Concrete

Concrete must be a minimum of 30 days old for resinous flooring applications. Primers are now available which can be used on fresh (green) concrete on some installations. Contact the technical department for details.

D. Previous Contamination can affect the bond of the resinous flooring and must be removed. Types of contamination are:
1. Oil, grease, or food fats can usually be burned off with a flame gun or removed with a commercial degreasing compound or solvent.
2. Curing compounds, sealers, and other laitance are best removed mechanically with:

a. vacuum shot-blasting

b. scarifying

c. sand blasting

E. Present Condition
1. Test for moisture: Coating system bond failures on slabs on grade and elevated/lightweight concrete caused by moisture vapor transmission are the industry’s largest single problem and result in extreme frustration from owners, clients, and contractors. Epoxy.com recommends testing for moisture vapor transmission. The recognized methods are:

a. ASTM-F-1869  Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride: The maximum allowed water/vapor transmission rate is 3 pounds per 1,000 square feet per 24 hours.

b. ASTM F-2170  Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using In Situ Probes: This test measures the relative humidity in the slab below the surface. If taken over a period of time, it will show the rate of drying in the slab. The maximum relative humidity should be below 80%.

c. ASTM-D-4263  Plastic Sheet Test: This test gives an indication that moisture may be present.

2. Moisture related failures can be prevented through:

a. Placing new concrete over an efficient vapor barrier.

b. Testing for moisture vapor transmission as prescribed above prior to resinous flooring application.

c. Applying a moisture vapor transmission reduction system where moisture content is too high for successful resinous flooring applications.

3. A clean surface is necessary to establish a strong bond between the resinous flooring and concrete.
4. Resinous flooring systems are only as sound as the concrete they are applied to. All unsound concrete should be repaired or replaced prior to resinous flooring applications. Consult your Epoxy.com Technical Service Department for specific information.
5. Resinous flooring materials should be applied to level concrete substrates. Grind or fill high and low spots prior to application.
6. Repair cracks prior to resinous flooring applications.
F. Mechanical Prep vs. Acid Etching

Resinous flooring materials ideally bond to concrete with a rough, sand-paper finish. This finish can be achieved by either acid etching or mechanical methods. The choice of preparation is dictated by the factors above. Other factors which determine the type of preparation include:

1. Ecological restrictions involved with waste removal which could prohibit the use of acid etching and other chemical methods.
2. The type of resinous flooring material: It is recommended that concrete floors be acid etched prior to application of polyester and vinyl ester flooring systems.
G. Acid Etching

The following steps are recommended for acid etching:

1. Dilute commercial muriatic acid with water using 1 part acid by volume to 3 parts clean water by volume. Add the acid slowly taking care to avoid splashing. Workers should be protected with safety glasses, rubber gloves, and boots. If skin or eye contact occurs, rinse affected area thoroughly with clean water and follow Material Safety Data recommendations.
2. Sprinkle acid solution onto the entire surface in order to allow the acid to reach all areas of the concrete. Adequate coverage is approximately 75 ft²/gallon of acid/water solution. Do not puddle and spread.
3. Scrub the acid solution into the concrete using a stiff bristle broom to remove loose concrete and laitancy.
4. Before rinsing, look for areas where bubbling did not occur. These areas have not been sufficiently cleaned and will require mechanical scarifying and additional acid etching.
5. When the acid solution has stopped bubbling (usually after approximately 15 minutes), rinse the floor thoroughly with water. Do not allow the floor to dry before rinsing because the salts formed by the acid reaction may cause problems with the adhesion and performance of the resinous flooring system. Test pH of the concrete surface to verify that the concrete tests alkaline.
6. Finally, the floor should be dry mopped to remove standing water and dirt remaining after the acid etching. Allow the floor to completely dry prior to the application of any resinous flooring system. Failures can occur in resinous flooring system applications due to moisture remaining in the substrate.
H. Mechanical Preparation

Contamination and other foreign materials must be mechanically removed to ensure a satisfactory bond. All dust and debris must be thoroughly removed.

II. OLD CONCRETE

Old concrete surfaces must be structurally sound. Any unsound areas must be repaired prior to proceeding with the resinous installation. For proper patching and repairing, use Epoxy.com Technical Service Department. Remove existing paint, scale and loose concrete by rough sanding, sandblasting, shot blasting, or grinding. In some cases where plant conditions allow, a stripper may be used to remove excessive build-up of paints or sealers.

Structurally sound concrete should be mechanically prepared to remove any contamination. Vacuum shot blasting is the best method for achieving a good profile for bonding and should be used where possible. Before installation of any Epoxy.com Product the surface must be examined for moisture vapor transmission using:

ASTM-F-1869 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride.

ASTM-F-2170 Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using In Situ Probes.

ASTM-D-4263 Standard Test Method for Indicating Moisture in Concrete by the Plastic Sheet Method. This test is only an indication and should not be used to determine moisture migration.

Other ASTM Tests which are applicable to concrete preparation are:

ASTM-D-4258 Standard Practice for Surface Cleaning Concrete for Coating

ASTM-D-4259 Standard Practice for Abrading Concrete

ASTM-D-4260 Standard Practice for Acid Etching Concrete

ASTM-D-4261 Standard Practice for Surface Cleaning Concrete Unit Masonry for Coating

ASTM-D-4262 Standard Test Method for Ph of Chemically Cleaned or Etched Concrete Surfaces

ASTM-C-811 Standard Practice for Surface Preparation of Concrete for Application of Chemical Resistant Resin Monolithic Surfacing

III. NEW CONCRETE

New concrete must be well cured and dry prior to coating. Allow to cure a minimum of 28 days unless using green concrete primer. No curing agents or sealing compounds should be used at any time prior to coating. A light steel trowel finish is recommended when finishing the concrete surface.

Any oil, grease, laitance, or other foreign material must be removed. Steam clean with a strong degreaser such as tri-sodium phosphate. Laitance and other foreign material are best removed by mechanical methods such as vacuum blasting, scarification, or grinding.

All new concrete can be acid etched or mechanically prepared by vacuum shotblasting, sand blasting, scarifying, or grinding. Vacuum shot-blasting provides the cleanest environmentally safe area during cleaning. It also provides a mechanically rough surface to achieve a good bond.

When acid etching, use a 3 to 1 dilution of water to acid and follow directions printed above.

Before the installation of any Epoxy.com resinous system, the surface should be examined for moisture. Test for moisture vapor transmission using ASTM F-1869 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride. The maximum allowable rate is 3 pounds per 1,000 square feet per 24 hours.

Another procedure that helps determine slab dryness is ASTM-F-2170  Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using In Situ Probes. Maximum allowable R.H. for protimeter test is 80%.

Poured Concrete Basement Waterproofing with Epoxy

September 18, 2014

This is the second half of a 2 part of a series on basement waterproofing with epoxy. In Part 1, we discussed waterproofing block wall foundations with epoxy. In Part 2A we discuss how to identify leaks that need waterproofing in basement walls, and floors that are made out of poured concrete. In this part (2B) will deal with epoxy injection repairs of cracks in poured concrete, that cause the leaks.

Earlier we discussed how many homes and businesses experience leaky basements year after year. The worse time is in the spring and after heavy rain. We discussed prudent things that you can do to improve drainage against your foundation. Epoxy Injection is designed to waterproof and give you the concrete’s structural integrity back.

Why Epoxy Inject the Cracks?

We discussed in our last article that cracking is a sign of failure caused by stresses, inadequate design, improper curing, etc. One of the dangers of a structural crack is the effect that it has on the reinforcing bar. The reinforcing represents one of the main structural values of the concrete. Cracks left unprepared allow water to enter your basement and attack the rebar.

Epoxy injection resin has two purposes:

  1. It effectively seals the crack to prevent the damaging moisture entry. Second, it monolithically welds the structure together.
  2. The injection also stops the infiltration of water into your basement.

Epoxy Injection Port Setting

Clean the concrete on both sides of the crack being careful not to force concrete dust into the crack. Concrete dust can be detrimental to the injection processes in several ways. Vacuum the area completely with a shop vac.

You need to determine the spacing of ports to be set. The spacing is a factor of the tightness of the crack and the depth of the concrete substrate. Spacing is normally between four (4) and eight (8) inches.

Port Setting and Sealing

Align ports directly over cracks. That allows injection resin to flow into the crack. Seal surface cracks and the ports in place. Sealing the exterior of cracks is done with Epoxy Gel #2006.

Selecting the Right Epoxy Injection Resin

Epoxy injection resin should typically be low viscosity injection resin- Epoxy Injection Resin #301. It must be low viscosity resin so it will flow in the smallest hair line cracks. Resin can travel several feet from the point of injection. It may take some time before reaching the next port or penetrating through pin holes in the surface. Epoxy injection effectively fills cracks including small voids and hairline cracks

Pumping Epoxy Injection Resin

The most economical way to deliver the epoxy injection is with the 450 ml binary injection system, a manual gun, or the pneumatically driven one. This uses a binary caulking gun with static mix tubes to inject the resin, insuring continuously mixed fresh material.

Limit pressure, low pressures allow gradual resin flow into the crack for deeper penetration. Start injection at the lowest point, and continues upward on the crack area. While injecting the lowest port, resin will flow to and out of the next higher port.

When pure resin is flowing out the next port cap, plug the current injection port and move to the next port. Then injection continues in the port showing resin flow. This procedure continues until all ports are full.

CONCLUSION

Epoxy injection is very effective at repairing concrete cracks and cutting of water infiltration. The right resin and equipment is critical. Epoxy injection makes a crack watertight while restoring the original structural integrity intended for the concrete. You can get all of the material you need to do this by contacting us:

Basement Waterproofing with Epoxy Part 2A

September 15, 2014

Poured Concrete Foundation Waterproofing

This is number 2A of a 2 part series on basement repairs. In Part 1, we discussed waterproofing block wall foundations. In Part 2A shows how to identify leaks that need waterproofing in basement walls, and floors that are made out of poured concrete. Part 2B will deal with the actual repairs to poured concrete leaks.

In our last piece we discussed how many homes and businesses experience leaky basements year after year. The worse time is in the spring after winter accumulation of snow. There are a number of prudent things that you can do to improve drainage against your foundation like roof gutters, grading and improvement of drainage. The recommendations here do not replace that conventional wisdom. It is designed to augment and improve upon these conventional methods.

Identifying the Source of the Basement Water Leak

The nice thing about poured concrete is that it holds water back very well. The leak typically happens at a cold joint or in a crack or hole in the concrete.

Concrete Cold Joints

Fresh (plastic) concrete doesn’t bond to hardened concrete. The exception is when a special epoxy bonding agent like Epoxy.com Product #2007 – is used (this bonding agent will be discussed in a future article). When concrete has hardened or has started to harden and you pour more concrete against it (without the right bonding agent) you get what is called a cold joint. These cold joints are a common source of water leaks.

Virtually all basements are built with a giant cold joint – the cold joint between the floor and the wall. Typically there is some sort of water-stops material installed in these joints intended to stop leaking at this cold joint. These water-stops can fail. So the wall to floor joint in a concrete basement is a frequent source of water leaks.

You can also get cold joints in the middle of concrete walls and floors due to multiple pours. You can get cold joints if concrete is setting to fast and fresh concrete is poured against semi cured concrete. Sometimes saw cuts in the floor can be a source of leaks

Form Ties

Then there are the ties that go through the concrete to hold the forms together on either side during the pour. If these form ties are not installed perfectly or if the concrete is not totally vibrated around them, these ties can act as a conduit to let the water in.

 

Wall and Floor Cracks

When concrete cures it shrinks that is called “plastic shrinkage”. That plastic shrinkage can and usually does result in the concrete cracking. These cracks are one of the easiest ways for water to get into your basement. If the water makes it to the fill side of the tank (under the floor or against the wall) it will typically leak out into your basement. You should look carefully for these cracks when looking for potential leaks into your basement. If you are able to investigate into the water infiltration into your basement when it is leaking it will be easy to see. If trying to find the source of leaks when the basement is dry you have to look for water marks on either side of the cracks and beneath the areas that might be leaking.

Repairing the Basement Leaks with Epoxy

In the next installment on this topic, I will deal with how you waterproof the cracks while structurally repairing them with epoxy and similar materials.

Basement Waterproofing with Epoxy

September 4, 2014

Many homes and businesses experience leaky basements year after year. The worse time is in the spring after winter accumulation of snow. There are a number of prudent things that you can do to improve drainage against your foundation like roof gutters, grading and improvement of drainage. The recommendations here do not replace that conventional wisdom. It is designed to augment and improve upon these conventional methods.

The following article will be 1 of 2. This one deals with Block wall foundations. The next one will deal with poured wall foundations.

Waterproofing Block Wall Foundations with Epoxy

One of the nicest features of most of our epoxies are that they are virtually 100% waterproof. Water simply cannot pass through a good healthy layer of properly applied concrete, block, wood etc. Epoxy also has an incredible bond to concrete, cement, wood and many other construction materials. The bond strength of epoxy to concrete and cement is greater than the tensile strength of the concrete. That means on properly prepared concrete, epoxy cannot be removed without pulling concrete with it. The same is true about wood.

Considerations in Waterproofing with Epoxy

All this gives you the perfect combination to make a block wall watertight. There are limitations however:

  1. In an ideal world the epoxy should be applied on the positive pressure side of the wall, the outside. This way the pressure of the water is pushing it into the wall. That helps to mitigate the likelihood that you get so much pressure on the concrete block that you fracture the block. Typically by the time you know you have a leak you are already backfilled and landscaped so 95% of the time it is not practical to do on the outside of the wall. So you do it on the inside instead.

    Water exerts a pressure of less than ½ psi per foot of water depth and most basement walls are only 8 foot high, so you would typically only see 4 psi. So it is unlikely that you have a pressure greater than the tensile strength of the block. So doing it on the inside is typically the only economical alternative.

  2. The Product #1W Epoxy is much more flexible than the concrete block and mortar, but if the mortar or concrete gets any significant cracks in it, it will crack through the coating. On the other hand, the system is very easy to patch if it does crack. We also make a wall grade version of our crack isolation membrane Epoxy.com Product #32 – www.epoxy.com/32.htm – which can reduce the potential for small cracks (which are the most common).
  3. A clean substrate is required for maximum effectiveness – www.epoxy.com/surfaceprep.aspx. For technical support contact me at norm@epoxy.com or 352-533-2167

Installation of Epoxy Waterproofing on Block Walls

Once the wall is clean, you need to point-up (fill) any cracks, bad mortar joints, and larger holes that are in the block. Some people use conventional mortar and wait 28 days for it to cure as per the American Concrete Institute. This is a very inexpensive way to do it, but can be affective if done properly. A more effective way to insure the right results is the use of Product #2005 Epoxy Gel Adhesive – www.epoxy.com/2005.aspx. That insures that you have a tight bond over the cracked areas and have already produced a tight waterproof seal in that area. Also the #2005 Gel Epoxy is semi flexible and allows more movement before cracking that conventional grout. The #2005 allows your coating to be installed the day after the #2005 is applied.

Once the cracks and holes are repaired, much of your work is done. You simply apply 1 coat of Epoxy.com Product #899 – www.epoxy.com/899.aspx – Epoxy Primer and allow to dry overnight.

After the primer has cured overnight you can apply the optional crack isolation membrane Product #32W – Wall Grade, or proceed to the coating below. If you do apply the crack isolation membrane 2 coats of the membrane are best. One advantage of the two coats of membrane is that typically you can reduce the number of coats of top coating that is required to seal the block. As you put on the membrane be sure to check to see that the holes in the block are being filled as you go.

Depending on the porosity of your concrete and if you used the crack isolation membrane above you will want to apply 2-4 coats of 1W epoxy wall coating. As you put on each coat check to see that the holes in the block wall are being filled.

Summary of Waterproofing Basement Walls with Epoxy

In conclusion: Leaking basements are a major problem to many structures in the spring. The easiest time to repair them is during the winter when there is little or no leakage. Epoxy.com epoxy coating systems can affectively and economically solve most basement leaking problems. The final product is a hard attractive ceramic like finish that does not require additional painting or other finishes over it.

Seamless Epoxy Flooring Systems Explained

August 25, 2014

Epoxy.com offers many different types of seamless flooring. We offer so many kinds that sometimes it confuses people. The purpose of this article is to explain the differences, and to help you choose the right epoxy seamless flooring system for your application. In some cases the right seamless flooring system will not even be an epoxy. It may be polyurethane or Methyl Methacrylate (MMA).

Epoxy.com Epoxy Chip Flooring in VT rest area.

Epoxy.com Epoxy Chip Flooring on a VT Interstate Rest Area – Taken over 15 years after installation.


Epoxy Floor Coatings

Epoxy coatings can be effective flooring systems. Using Epoxy as a flooring system you need a 100% solids, zero voc, hard durable coating. You also want a coating that is available in multiple colors. These floor coatings can last for decades, so you want to pick a color that you like. Properly installed you will be looking at this floor coating for a very long time. This kind of flooring system is available in the following options:

  1. Epoxy.com Product #1 – www.epoxy.com/1.htm – meets all the criteria above. It has good chemical resistance, and excellent cost to benefit ratio. Great for warehouses, in areas with high traffic and only modest chemical exposure.
  2. Epoxy.com Product #1ESD – www.epoxy.com/1esd.aspx. This is the same as product #1 above but has conductive filler in it. Depending on the primer you use under this system it can be conductive (100,000 – 1,000,000) ohms of resistance or Electro-Static Dissipative (ESD) which is 1,000,000 to 1, 000,000,000 ohms. Used in plants that produce explosive materials like ammunition, fireworks, flairs, or explosive solvents, and used in areas of sensitive electronics, like computer server buildings, avionics, electronics assembly and electronic production areas.
  3. Epoxy.com Product #2 – www.epoxy.com/2.aspx. This is similar to product #1 but with a much higher chemical resistance. This major increase in chemical resistance is offset by only a small increase in the cost of the #2 over the Product #1. The product #2 is well suited for applications like garages, machine shops, sewer tank floors, battery rooms, cooling towers, grooming shops, dog kennels and all areas where an economical chemical resistant coating is required.
  4. Epoxy.com Product #633 – www.epoxy.com/633.aspx – is a highly chemically resistant epoxy floor coating and flooring system. Like Product #1 and Product #2 is extremely durable. Product #633 is typically used in areas where containment of aggressive chemical is imperative. For example Product #633 will hold up to continuous exposure of 98% Sulfuric acid for a period of at least 6 months without loss of structural integrity. Great for secondary containment for a large number of chemicals.

     

All the systems above can go over many different types of substrates with the proper surface preparation. All of the products above are available in 17 colors and can be color matched for an additional cost. The systems above can be combined with various anti-skid materials or broadcast with silica broadcast aggregate to produce a thicker floor

 

Chip Floor

Epoxy.com Chip Flooring – www.epoxy.com/chips.aspx – is the perfect blend of economy, durability, low maintenance, and gorgeous appearance. It uses a 100% solids pigmented epoxy base coat, a full broadcast of plastic chips, and two coats of chemical resistant clear glaze. The chemical resistant glaze also makes this easily the most non-yellow epoxy top coat available today. This easy to clean chip flooring system is best for high traffic areas where appearance, durability and low cost of ownership is a must. Great for commercial and residential kitchens, bathrooms, showers, grooming shops, kennels, veterinary clinics, garage floors, show rooms, rest areas, and much more. This product can be installed with an integral cove base. Epoxy.com Chip Flooring can be installed by a contractor but easy enough to be installed by a home owner. Epoxy.com Chip Flooring can be installed in a residence but is rugged enough to be used in the most demanding commercial applications.

Quartz Flooring

Quartz Flooring Product #15 – www.epoxy.com/15.aspx has a long history of being durable, attractive and non-yellowing. I personally installed this product on high school bathroom floors in the mid 70s. These floors have held up to the test of time with little or no wear, little or no loss of shine and little to no yellowing even under the urinals. This is also available with an integral cove base

Solid Colored Flooring

These solid colored floors are based around self leveling, trowelable or double broadcast application techniques. These floors are sometimes called shop floor. They are made to be thick and extra durable under extremely harsh environments. They can be top coated with any of the systems above under coatings. This kind of flooring is available in 3 speeds of cure: normal, fast, and cold cure. Solid colored flooring is also available with an integral cove base.

Methyl Methacrylate (MMA) Flooring

The big advantage of MMA is speed of curing. Each coat of MMA will cure hard to the touch in 1-2 hours. This allows the next layer to be applied quickly and traffic to be returned to it quickly. You can even build a fast setting integral cove out of MMA resin.

I personally installed MMA on one kitchen floor with a very tight schedule. The restaurant was only closed for breakfast. The project started with rotten plywood floors. At 10 PM the carpenters came in to work. They removed rotten floor and floor joists. They replaced the floor joists and the plywood. At 5 AM I went in with my crew and we primed the floor and sealed up the joints in the wood and the screw holes. At 6:30 AM we laid the floor. At 8 we put a glaze coating on the floor and by 10:30 the restaurant workers were on the floor prepping for lunch. The floor installation from start to traffic took just 5.5 hours.

Polyurethane Decking Systems

Polyurethane Decking – http://www.epoxy.com/elastomeric.aspx – is the system best used in areas where maximum flexibility is necessary. This is typically outdoors, waterproof applications like balconies.

Specialized Flooring

We have a number of systems that are specialized flooring like conductive and ESD (Electrostatic Dissipative) flooring – www.epoxy.com/conductive.aspx – and various hybrid systems. If your project does not seem to fit in the categories above email me at norm@epoxy.com or call us at 352-533-2167.

 

In conclusion we offer many types of seamless flooring systems, they can be used for commercial and residential applications. These systems are durable, economical, and easy to install even by homeowners. These seamless flooring systems may be made out of epoxy, polyurethane, or methyl Methacrylate (MMA). Seamless flooring systems are available in multicolored or solid colored. They range in chemical resistance from very good to resistant to aggressive chemicals.

About 20 years I had a half way house that came to me and wanted a virtually indestructible waterproof group bathroom. They needed it to be like a shower enclosure for the entire bathroom, and toilet facility. It needed to be easy to thoroughly clean and disinfect.

The resulting system allows you to hose down the entire ceiling, wall and floors. The system that we developed is a completely seamless, waterproof ceiling and coating system. This epoxy ceiling and wall coating is seamlessly integrated with a seamless flooring system. This system is now being used for everything from clean rooms to animal facilities to car washes, daycare centers, assisted living facilities, food processing facilities and more.

The System

Ceiling and Walls

Prime the ceiling and walls with Epoxy.com Product #899 Primer – www.epoxy.com/899.aspx. Product #899 Primer is a 100% solids, low viscosity, moisture tolerant epoxy. It soaks deeply into the substrate, verifies surface preparation, and helps to prevent the much thicker coating from getting bubbles that may be cause by air or moisture trying to escape from the substrate during curing. Allow primer to get hard to the touch.

Before the epoxy primer is 24 hours old (and after the primer is hard to the touch) apply a coat of Epoxy.com Product #1W. The 1W – Wall Coating is 100% solids. It comes in a range of different colors. This means it is zero (0) VOC with no solvent. Just like the 899 Primer the 1W has very little odor. We have even more chemical resistant wall coatings for applications where it is chemicals that are being splashed or sprayed. Contact us if you have strong chemical exposures that you want to contain instead of water.

Let the first coat harden to the touch and before 24 hours add another coat of #1W. Allow the coating to dry over night.

Seamless Epoxy Cove – Optional

Typically the cove is only installed if you are going to install one of the multi-colored flooring systems (Waterproof Floor Options 2 & 3below). Cove is covered in an earlier blog – https://news.epoxy.com/2014/06/25/seamless-epoxy-cove-installation-instructions/. The cove gives you a radius at the bottom of the wall making the floor to wall transition easy to clean and esthetically pleasing.

Seamless Epoxy Flooring System

There are multiple systems that you can use for your seamless flooring portion of the system.

Water Proof Floor Option 1 – Seamless Epoxy Floor coating:

Floor Coating Systemwww.epoxy.com/1.htm. Product #1 applies with the Product #899 primer under it and in 2 coats just like the 1W. The Product #1 is thinner and flattens better on a floor than the Product #1W. You can also add an optional anti-skid to the #1 Floor Coating. The #1 comes in all the variety of colors of #1W.

Waterproof Floor Option 2 – Seamless Epoxy Chip Flooring:

Chip Flooring Systemwww.epoxy.com/chip.aspx is a two component 100% Chemical Resistant Epoxy Chip Flooring. System #315 Seamless Epoxy Multi-Colored Chip Flooring is available in virtually limitless color combinations. If your job is big enough our chips can be pigmented to match all the colors of many major paint companies. We can color match our base coat colors as well. Unless the pigments for your custom colored 315 Basecoat are unusually expensive we can color match for a modest small batch charge or at no charge for larger orders. Even our standard color pallet offers you over 45 chip colors that can be blended in any combination and percentage as you want. This gives you the architectural choices you need. The top coating for this system is highly UV resistant so since it doesn’t chalk indoors it can last and look great for decades.

Waterproof Floor Option 3: – Seamless Epoxy Quartz Flooring:

Quartz Flooring System with Product #15 – www.epoxy.com/15.aspx – is also an excellent flooring system for those who like the colored sand look with a good midrange chemical resistant system.

Waterproof Floor Option 4 – Seamless Chemical Resistant Flooring:

We can also help you to combine the systems above with our Novolac Epoxy Systems – www.epoxy.com/novolac.aspx for highly chemically resistant versions of those systems. You can also install an Electro-Static Dissipative or Conductive system www.epoxy.com/conductive.aspx.

 

In conclusion the systems above are only a small fraction of the possibilities. With our wide range of colors and chemically resistant systems the possibilities are endless. Please contact Epoxy.com Technical assistance at 352-533-2106 or email me directly at norm@epoxy.com.


Seamless Epoxy Cove Installation Instructions

June 25, 2014
Epoxy cove detail

Epoxy Cove Detail. Click image above to enlarge.

One of the unique advantages of seamless flooring is the ability to build an integral cove base. This integral cove allows you to create a virtual bathtub or shower base out of your seamless floor. Building this cove was a difficult job until the introduction of Epoxy.com Product #720 Coving Gel – www.epoxy.com/720.aspx. The coving gel is mixed with special fillers to create an easy to install custom built floor to wall base cove.

Advantages of a Cove Base

  • Prevents water from going under the walls
  • In chemical containment applications contains the chemicals to the coved area
  • Makes it easy to clean and disinfect the edges of the floor
  • Does not allow bacteria or insects to hide under the wall
  • Gives the floor an attractive professional seamless look
  • Required by government officials in many food and pharmaceutical applications

Step 1, Surface Preparation

All high quality installations begin with proper surface preparation. The substrate must be clean, solid and porous. The substrate must be free of paint, sealers, oil, grease or any other contaminants that will interfere with the soaking in of the epoxy primer – www.epoxy.com/surfaceprep.aspx. Be sure the floor and wall in the areas near the cove are clean. That will help prevent dragging dirt and other contamination into the cove and make the tape to mask the cove stick better.

Step 2, striking a line

Cove is typically installed at 4 inches high, but specialty applications may be as little as 2 inches or as much as 6 or 8 inches or even more. Once you know the height of the cove it must be decided if the top of the cove will follow the contour of the floor or be level on the top. Most floors look best with a level top to the cove.

Strike a line with a laser level or a chalk line. Mask with a strong firmly bonding tape like duct tape. Be sure it is pressed down and securely stuck to the wall.

Step 3, priming

Make a small batch of Product #899 primer. Apply the primer on to the area to receive cove. This application is typically done with a brush or mini roller. It is important not to put the primer on too thick or it will run. You just need to have enough primer to give the surface to receive the cove a wet look.

If you have a very porous substrate and the primer soaks in and doesn’t look wet, a second coat of primer may be required. A typical substrate that will sometimes need a second is sheetrock. If a second coat if primer is required it can be put on before the first coat has hardened. Remember never to wait more than 1 day before recoating any epoxy.

Step 4, mixing the cove material

After the primer gets tacky and before the primer gets tack free (not sticky to the touch) you will need to install your #720 cove mix. If your primer becomes hard before you start troweling up you cove you must prime again. Colored quartz has different coving batch formulations than other seamless flooring types. Be sure to consult www.epoxy.com/720.aspx, for more information about cove mixes.

Step 5, troweling up the cove

Using a margin trowel “rough in” the cove mix material onto the wall where the cove is going. Be careful not to lift the tape creating the top seal in the process. Smooth the cove to shape using a cove trowel.

After the cove starts to get slight stiff it is time to make a final pass at smoothing the cove with your coving trowel. Be sure not to wait too long or the tape will be difficult to impossible to remove. Be sure to keep your trowel clean so it doesn’t drag the epoxy cove material and make it rough again.

A few drops of a dish washing detergent (like Dawn) in warm water make a great way to clean your trowel and slick up the cove. Use a rag to clean the cove in the water. Remove the cove trowel from the water and remove the excess water. Then return to slicking down your cove.

Once the cove is smooth enough, remove the duct tape, carefully. Remove the tape at an angle pulling the bottom first so the excess coving material on the tape stays on the tape and does not fall onto the cove. If pieces do fall on the cove gently remove the pieces and gently smooth out the damage.

Use our margin trowel to smooth the top of the cove where you just removed the duct tape. Use the warm water and dishwashing detergent to keep your trowel clean and slick the top of your cove.

Clean the excess material off from the bottom edge of your cove, unless you have already done this earlier.

Step 6, sealing the cove

After the coving material has hardened overnight, inspect and lightly sand out any minor imperfections.

Apply appropriate sealers (listed below). When in doubt, contact Epoxy.com Technical Support. Apply coating/sealer over the cove by brush and/or squeegee. Be sure that you do brush out or squeegee out any runs. Keep going back and checking for runs until satisfied that the glaze (top coating / sealer) will not run.

  1. Quartz coves are sealed by applying Epoxy.com Product #15 – www.epoxy.com/15.aspx.
  2. Pigmented Epoxy Coatings, use the same material that you are using on the rest of the floor.
  3. Chip Flooring.
  4. Apply Epoxy.com Product #315 Top Coating by brush over the cove mix.
  5. Then broadcast the cove into the wet material. If you are careful you can push the chip up into the coating with your hand or a piece of cardboard or similar material.

Step 7, install your floor

Install your floor in accordance with manufacturer’s recommendations.

Patching Floor with Epoxy

July 18, 2017

Here is an outline of the procedure for patching with Epoxy.com Product #1 and Product #10.  Cold cure is identical but you should make even smaller batches and work even faster.

  1. Mix a small amount of the #10 (mix ratio 2A: 1B).
    1. Measure accurately and mix for 3 minutes with a proper size mixer.
    2. Typically very small batches less than a quart can be mixed with a stir stick.
    3. Larger batches should use a mixing paddle in a low speed drill or similar. Typically  mixing paddles are 5 inches or more in diameter.
  2. Apply a primer coat of #10 at a rate of 250-300 SF per gallon (typically done with a roller) to the substrate the mortar is to be attached to.
    1. Typically you will allow this to harden to the touch to make troweling into it easy.
    2. You can trowel into the wet primer in the case of small patches.
  3. Mortar Patch
    1. Mix another small batch of #10, using the methods in step 1 above.
    2. Add Product #82 Mortar Blend Aggregate to the mixed resin in 3a. You can add as much as 50 to 75 lbs. of mortar blend aggregate to a gallon of mixed #10 resin. If the material appears to wet you can add more, if it is too dry add less.
    3. Quickly trowel the patch into place.  Winter Cure Epoxy can set very fast in the bucket.
  4. Sealer Coat
    1. After the patch in step 3 has hardened, you can grind off any high spots and fill more material again if needed.
    2. Then seal the top of the patch.
  1. Product #10 is thinner than the #1, making it an excellent sealer for sealing up the patch.
  2. Alternately you can go directly to a very thin coat of #1
  1. Top Coat
    1. Mix small batches of #1 using the methods used in #1 above.
    2. Mix optional Antiskid fine into the coating above at a rate of 8-16 volume ounces of Anti-skid per gallon of mixed resin.  12 ounces per gallon is typical.  This is done by mixing the resin first, adding the anti-skid and mixing for another min.
    3. Quickly apply the material with a roller at a rate of 160-200 SF per gallon per coat.  Two coats is recommended.
  2. Please read all the information below before starting your project.
