Scores of customer have taken full advantage of our systems to make spaces very easy to disinfect. Some of them have used our seamless systems on their floors, walls and ceilings. These seamless systems have no place for a virus or bacterial to hide. They are using enhanced disinfecting, and doing so without harming our material.
We can show you how to do this to your facility. Here are some of the kinds of places that this has been done. At minimum most do floors and cove.

How do I stop chemicals gas vapors from contaminated soils passing though a concrete slab? This is a question I get frequently from owners and environmental mitigation experts.
Chemical contamination vapors tend to pass though a concrete slab and get into the air above. Stopping the migration of the gas through a slab is frequently a requirement of repurposing a space.
The following steps can be used to mitigate chemical vapors into your space above it. Without the right tools these vapors in the air from contamination under that slab can be quite pervasive.
Each job needs to be evaluated on an individual bases. The tools below make the solution less evasive.
Cracks through the Concrete Slab
The most direct way for soil contamination gasses to get in is through cracks. Cracks are the path of least resistance, so most of your vapors come through cracks in the floor. That is a very easy fix Product #684LV – Methyl Methacrylate Crack Healer and Sealer.
The #684LV has about the viscosity (thickness) of diesel fuel. That makes it easy to gravity feed into small cracks small porous areas of the concrete. It welds the cracks back together with a bond strength that is greater than the tensile strength of the concrete. In other words structurally you have the monolithic structure that the concrete was intended to be.
Expansion joints are the also a very direct route for vapors to come in. To seal these joints use Product #632 – Chemical Resistant Joint Filler. This is a highly chemical resistant joint filler. It will not only keep the vapors out. If there is going to be a chemical exposure to the surface there will it will stop the chemicals from attacking your concrete and further contaminating the soils below it.
This is where there is a couple of ways to go. You can apply an additional coat or coats of the #12 or go on to Coating the Concrete Slab below. Our optional translucent Synthetic Anti-Skid Fine may be added to the #12 if it is used in additional coats as a clear sealer.
The Product #12 Primer Sealer can also be mixed with silica sand and used as a patching material for potholes and otherwise damaged concrete if required.
Coating the Concrete Slap
In many cases you will want to install a coating over the concrete slab. There are a number of options for doing this but here are a few of the most common ones. The biggest difference between these coatings is the chemical resistance. Please See Chemical Resistance Chart for a comparison of chemical resistance of the products below. All of these products are 100% solid, zero voc. All of the coatings in this section are highly durable and resist the abrasion of traffic.
Epoxy.com Mortar Systems can be used to make permanent repairs that no other kind of product can make. The purpose of this blog is to give you an overview of what you can use and how to use it.
Product Selection – The following are a list of Epoxy.com Products that make excellent epoxy mortars All the products listed below are zero (0) VOC, so it meets even the strictest low VOC requirements, and meets Indoor Environmental Quality/Air Quality (LEED IEQ 4.2 Indoor Emitting Materials Credit). See the individual product component technical data sheets and MSDS for further information.
First and foremost is good surface preparation. Good surface preparation is necessary for most if not all patches to have long term success: www.epoxy.com/surfaceprep.aspx.
Prime the bottom of the whole with some of the neat mortar resin. Neat mortar resin is the liquid (A&B) mixed at the proper mix ratio and stirring in a way to insure a completely mixed product. This will typically take about 3 minutes.
Mix some of the neat epoxy into the Epoxy.com Mortar Blend Aggregate #82 or other appropriate dry clean silica sand gradation.
The amount of sand aggregate depends on the aggregate used.
Typically, the Epoxy.com Product #82 Mortar aggregate can be added at a rate of 18 to 27 lbs. of #82 per 1.5 Qt of mixed resin (1Quart of A to ½ Quart of B).
You will need to recalculate the sand above when using a different sized batch. This is doubly true if using one of or 4:1 mix ratio material.
Shallow patches tend to be a smaller amount of sand filler.
Deeper patches tend to be on the higher side.
If you get a lot of resin to the surface your mix is too wet. If your mixture after it hardens is porous, or weak then you have added too much aggregate.
For a better finish in very deep pours do it in 2 lifts.
Fill all but the last ¼ inch plus or minus with your dryer mix. Allow to cure hard (typically overnight).Fill with a wetter mix on top of that after the first one has cured.
To ensure proper adhesion between layers never wait more than 24 hours between layers.
It is always better to have your patch slightly higher rather than to low. If you are slightly high you can grind the patch back to level. If to low you will need to fill again.
For very shallow fills (1/32 or so) where the sand particles are to large you can use any of the following:
EPOXY.COM PRODUCT #442 is a two component water- based
aliphatic (non-yellowing) polyurethane. Product #442 is free of the
health and environmental problems normally found in solvent-based
urethanes, while maintaining excellent performance properties. Product
#442 is also available in an ESD formulation which must be applied over
a base coat of Epoxy.com Conductive Epoxy.
EPOXY.COM PRODUCT #442 polyurethane provides a gloss finish. Product
#442 has good chemical, stain, and mar resistance. In addition, it’s easy to clean
and has excellent color retention under heavy foot traffic.
EPOXY.COM PRODUCT #442 is a high performance coating
for use in a variety of seamless floor and wall coating systems. Product
#442 eliminates the strong solvent odor normally associated with high
performance materials. It’s ideal for topcoats and finishes that require
high abrasion resistance. Typical application areas are clean rooms,
hospitals, pharmaceutical facilities, stained concrete, wood floors, and
as a seal coat for most Epoxy.com floor and wall

Surface Preparation Procedures..
Mix only that amount of material that can be used in a two hour period. In hot weather,
plan work for the cooler times of the day.
If using less than full units, proportion the amounts carefully and mix for 2-3
minutes using a low speed drill, scraping the bottom and sides of the mixing vessel.
DO NOT ADD WATER.
Apply Product #442 polyurethane at a spread rate of 275-300 square feet per gallon
to achieve 2.0-2.5 mils dry. Thicker application may result in bubbling in the cured
