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.
  7. Prime the inside of the containment area with Epoxy.com Product #12– www.epoxy.com/12.aspx  – Chemical Resistant Primer, and allow to cure overnight.
  8. Install 2 coats of Epoxy.com Product #633 – www.epoxy.com/633.aspx – Chemical Resistant Novolac Epoxy Coating.

Summary

Doing an effective job of building secondary is easier than you may think. For more information visit our website at http://www.epoxy.com, call our technical support department at 352-533-2167 or email us at info@epoxy.com.


Cold Temperature Epoxy

Installing Epoxy in Coolers and Cold Temperature

Extend Epoxy Installation Season into Winter

I have spoken on this subject here before but this time of year I get a lot of calls and emails about installing epoxy in cold temperatures. 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.

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
