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.

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 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.

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.
  1. Do with Epoxies
  2. Don’ts with Epoxies

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


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.

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
