Applying New Epoxy over Old Epoxy

February 13, 2015

I frequently get calls and emails from folks who want to install our epoxy over an existing epoxy floor or coating that they have. They want to know if it is okay to go over it and what they have to do to properly prepare the surface.

If the existing epoxy is a good hard solid one that is well bonded to a well prepared substrate it is possible. On the other hand if you are replacing it, what is wrong with the existing epoxy? Has the existing epoxy been badly abused by heavy sharp objects being dragged on it? Was the exiting epoxy damaged by chemicals beyond the chemical resistance of the existing epoxy? Are you just trying to upgrade the look of the existing epoxy?

You should be concerned about going over epoxy that is coming loose from the substrate. That may mean that there was poor surface preparation. It may also mean that the quality of the epoxy might not be what it should be. You need to be concerned about epoxy that is wearing out. If it is wearing out you want to know why. My company and I personally started out as installers of epoxy. I have never seen or been made aware of any of Epoxy.com coatings and/or flooring systems that have worn out have come loose from the concrete. I have seen concrete so pounded by traffic that it came loose, but our epoxy was still attached and still doing its job. That is based on over 30 years of field experience with the products.

Back to the question, “can I put epoxy over epoxy?” I always assume that the reason that the epoxy is wearing out or coming loose is that the epoxy is low quality or the installation was poorly done or both until I can prove otherwise. The way that I do that is to attempt to grind or shot blast off the existing epoxy. If after a substantial effort the epoxy cannot be removed and I cannot hear a hollow sound under the existing epoxy, I feel I have proven that the existing material is solid and well bonded.

Let’s take a moment to discuss that dreaded hollow sound above. If the flooring system or coating is very poorly bonded you will get a sound from your grinder like you are dragging a piece of paper or a piece of stone under the grinder, or rubbing stone. When you tap it with a hammer you get a hollow higher pitch noise than you get when you tap solid concrete or a solid floor over concrete.

You must be sure that the substrate is free of all types of contamination, including but not limited to oil, grease, food fats, curing compounds, sealers, laitance, dirt, wax etc. The existing epoxy left behind must be well bonded, and sanded until it has no shine. See Epoxy Surface Preparation Procedures for more information on this subject.

The beauty of trying to get it off is you are removing all the shine and getting it ready to accept another layer of epoxy. Just before I install the new layer of epoxy I solvent wipe with xylene, let it dry. Then I recommend a coat either Epoxy.com Product #899 Primer or Epoxy.com Product #12 Chemical Resistant Primer. Then install epoxy as usual. For more surface preparation and installation tips please visit or “Where to Start” page at: http://www.epoxy.com/start/default.aspx

Epoxy Cold Temperature

January 29, 2015

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., 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.

Take your pet to work week is June 16-20. Take your dog to work day is June 20th

Every day is “take your pet to work day” in the offices of Epoxy.com. We believe the bond between pet and owner is a special one. Pet owners who have their pet with them during the day at work (in a pet safe environment) don’t have to worry about how their pet is doing at home alone. Besides the owners of the company want to take their pets to work with them so it is only fair.

Why Use Epoxy.com Products in “Green” Buildings?

August 20, 2012

110614_2044_EpoxyChipFl10.pngEpoxy.com’s 100% solid products (which are most of our product line) are included in many “Green” buildings. The logic for that is this:

1. Epoxy.com 100% solid products have  no VOCs. So you are reducing the carbon emissions.

2. Typical Epoxy.com 100% solid systems have done their job for decades, and there is no reason to believe they will not last for decades more. I personally have jobs that I installed with them that go back as much as a third of a century, that are not even starting to show signs that they will need replacement. That is the ultimate in reuse.

3. There is no need to recycle a product that can be reused for decades, but you can use recycled materials like glass aggregate in the epoxy matrix.

Epoxy.com encourages our customers to order material as they need it and to use all their materials before their expiration. That is why we do not require large stocking orders from new dealers, like most other companies. We want our customers to use up material they buy from us and not have any for it run out of shelf life. However, if Epoxy.com products do run out of shelf life, they are typically mixed and cured before disposal as is consitered in under most if not all local regulations as inert as common trash.

Pot Life of 100% Solids Epoxy

June 7, 2012

As the Technical Support Director of Epoxy.com  I get a lot of email and phone calls about how to work with the relatively short potlife (typically 30-40 minutes) of 100% Solids Epoxy and similar resin systems.

It is important to understand that  Epoxy (and epoxy like resins) generate their own heat when mixed. So larger batches of epoxy  will generate more heat then smaller ones. The result of this is that larger batches of epoxy set faster than smaller batches. Start by mixing smaller batches of epoxy and then increase your batch size slowly.

To give you longer working times:

  • Make small batches that you can use in about 1/2 the working time of the material.  That will give you a little wiggle room and it will make your epoxy easier to use.
  • Be sure the product is cool when you mix it.  For best handling properties I like my material in the upper 60’s or lower 70’s. F.
