Disinfecting Epoxy.com Coatings and Flooring

March 17, 2020

We have many of our customers and their clients doing enhanced disinfecting of Epoxy.com Flooring and Coating Systems. I want all of you to concentrate on worrying about killing viruses and germs, and not worry about damaging the epoxy coatings and flooring you have purchased from us. Be sure to follow the NIH method with bleach below.

The National Institute of Health “Infection Prevention and Control of Epidemic- and Pandemic-Prone Acute Respiratory Infections in Health Care” recommends “1:100 dilution of 5% sodium hypochlorite is the usual recommendation. Use 1 part bleach to 99 parts cold tap water (1:100 dilution) for disinfection of surfaces.
Adjust ratio of bleach to water as needed to achieve appropriate concentration of sodium hypochlorite. For example, for bleach preparations containing 2.5% sodium hypochlorite, use twice as much bleach (i.e. 2 parts bleach to 98 parts water).”

You can feel confident to disinfect all Epoxy.com epoxy Flooring and Coating products, this way. Please contact Epoxy.com Technical support with any additional questions that you have at 352-533-2167 or email me directly at norm@epoxy.com


Mitigation of Concrete Slab Chemical Vapors

January 29, 2020

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.

Background

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

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.

Sealing the Surface of the Concrete Slab.

The next step is to prime the concrete with Product #12 Chemical Resistant Primer / Sealer.

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. 

UV Resistant Top-Coating

For jobs that will see direct sunlight.  It may be desirable to add an ultra violet (UV) Resistant top coating for the systems above.

Epoxy Mortar Installation

June 19, 2019

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.

  1. 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.
  2. INSTALLATION:
    • 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 Stone Maintenance.

May 16, 2019
Picture of Epoxy.com stone
Epoxy.com Epoxy Stone

A customer asks, “I have a patio with Chattahoochee or Chattahoochee like stone glued together with epoxy. It is no longer shinny and the stone is starting to come loose. What is causing this and what should I do about it?”

It sounds like you have a stone that was installed with Epoxy.com Product #17 – www.epoxy.com/17.aspx – or some other brand of stone adhesive. We tell all of our customers that install epoxied stone that they need to maintain by re-glazing it periodically. Unfortunately, not everyone is as forthright as us in telling their customers this.

We recommend you take these steps every spring and fall so you can enjoy your epoxied stone year-round.

1. Look at you epoxy stone and look determine if it needs maintenance. If it is still shinny and you don’t have loose stone, then you are done. Come back and do this step again in 6 months.

2. Clean your stone to remove algae, mold, oil, grease and any other contaminants from it. Typically, contamination is just algae and mold and can be removed with a weak Clorox and water combination with a thorough rinse with a hose or gentle pressure wash. Allow your stone to dry completely before proceeding.

3. Determine if it has only lost its shine or if you have loose stone. Decide if sections of the stone are so loose that they need to be reinstalled with Product #17 (4 below) or if there are just a few to no loose stones and you just want to re-glaze it (5 below).

4. If stone needs to be picked up and reinstalled in areas do that with Epoxy.com Product #17. Contact Epoxy.com Technical support for the amount of product you need. We can also go over the reinstallation of these areas with you. If the stone is sound or has just a few stones that you are not worried about replacing you can proceed to 4 below.

5. Apply 1-2 coats of Epoxy.com Product #15 (depending on how bad the stone has weathered) to the top of your clean dry stone. This will give you back your original shine and strengthen the interface (bond line) between the stones. Product #15 is the best product to do this with as experience has shown it lasts 1.5 to 2 times longer than convention epoxies used for this application.

6. CAUTION: You can find single component so called “Chattahoochee” . These sealers add shine to your epoxy stone but do not strengthen the interface between the stone. Using this kind of sealer can ruin your epoxy stone. Once these inexpensive sealers are on they are difficult to impossible to remove. Making it optionally impossible to ever re-glaze the epoxy stone properly again.

As always when in doubt contact Epoxy.com Technical support at info@epoxy.com or by calling 352-533-2167.


Epoxy on 316 Stainless

November 16, 2018

A customer writes:

“I’m an architect with a project under construction…

“There is a hazardous materials room in the building where various corrosive products will be stored. The materials are stored in the middle of the room on a large collection pan and the entire floor below that is constructed of stainless steel bar grating – held up off the concrete slab.

“Per the direction of the engineers we have required the contractor to essentially coat all the surfaces in the inside the room with your epoxy Novolac 633

“Now a question has come up about whether or not the 633 will adhere to stainless steel bar grating made from 316 stainless?

“Could you address that for us?”

My Answer:

That is an excellent question.  316 Stainless is very hard to bond to.  Many of our customers have had excellent luck with the following procedure however.

  1. If possible sandblast the stainless to get a profile.  If that is impossible grind/sand it the very best you can to create small scratches everywhere and remove the shine.
  2. Coat with Epoxy.com Product #660 Aluminum Filled Primer – www.epoxy.com/660.aspx . Allow to cure hard to the touch
  3. Apply 2 coats of Epoxy.com #633 or. 633W (Wall Grade).
