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

Seamless Epoxy Flooring Systems Explained

August 25, 2014

Epoxy.com offers many different types of seamless flooring. We offer so many kinds that sometimes it confuses people. The purpose of this article is to explain the differences, and to help you choose the right epoxy seamless flooring system for your application. In some cases the right seamless flooring system will not even be an epoxy. It may be polyurethane or Methyl Methacrylate (MMA).

Epoxy Floor Coatings

Epoxy coatings can be effective flooring systems. Using Epoxy as a flooring system you need a 100% solids, zero voc, hard durable coating. You also want a coating that is available in multiple colors. These floor coatings can last for decades, so you want to pick a color that you like. Properly installed you will be looking at this floor coating for a very long time. This kind of flooring system is available in the following options:

  1. Epoxy.com Product #1 – www.epoxy.com/1.htm – meets all the criteria above. It has good chemical resistance, and excellent cost to benefit ratio. Great for warehouses, in areas with high traffic and only modest chemical exposure.
  2. Epoxy.com Product #1ESD – www.epoxy.com/1esd.aspx. This is the same as product #1 above but has conductive filler in it. Depending on the primer you use under this system it can be conductive (100,000 – 1,000,000) ohms of resistance or Electro-Static Dissipative (ESD) which is 1,000,000 to 1, 000,000,000 ohms. Used in plants that produce explosive materials like ammunition, fireworks, flairs, or explosive solvents, and used in areas of sensitive electronics, like computer server buildings, avionics, electronics assembly and electronic production areas.
  3. Epoxy.com Product #2 – www.epoxy.com/2.aspx. This is similar to product #1 but with a much higher chemical resistance. This major increase in chemical resistance is offset by only a small increase in the cost of the #2 over the Product #1. The product #2 is well suited for applications like garages, machine shops, sewer tank floors, battery rooms, cooling towers, grooming shops, dog kennels and all areas where an economical chemical resistant coating is required.
  4. Epoxy.com Product #633 – www.epoxy.com/633.aspx – is a highly chemically resistant epoxy floor coating and flooring system. Like Product #1 and Product #2 is extremely durable. Product #633 is typically used in areas where containment of aggressive chemical is imperative. For example Product #633 will hold up to continuous exposure of 98% Sulfuric acid for a period of at least 6 months without loss of structural integrity. Great for secondary containment for a large number of chemicals.

     

All the systems above can go over many different types of substrates with the proper surface preparation. All of the products above are available in 17 colors and can be color matched for an additional cost. The systems above can be combined with various anti-skid materials or broadcast with silica broadcast aggregate to produce a thicker floor

 

Chip Floor

Epoxy.com Chip Flooring – www.epoxy.com/chips.aspx – is the perfect blend of economy, durability, low maintenance, and gorgeous appearance. It uses a 100% solids pigmented epoxy base coat, a full broadcast of plastic chips, and two coats of chemical resistant clear glaze. The chemical resistant glaze also makes this easily the most non-yellow epoxy top coat available today. This easy to clean chip flooring system is best for high traffic areas where appearance, durability and low cost of ownership is a must. Great for commercial and residential kitchens, bathrooms, showers, grooming shops, kennels, veterinary clinics, garage floors, show rooms, rest areas, and much more. This product can be installed with an integral cove base. Epoxy.com Chip Flooring can be installed by a contractor but easy enough to be installed by a home owner. Epoxy.com Chip Flooring can be installed in a residence but is rugged enough to be used in the most demanding commercial applications.

Quartz Flooring

Quartz Flooring Product #15 – www.epoxy.com/15.aspx has a long history of being durable, attractive and non-yellowing. I personally installed this product on high school bathroom floors in the mid 70s. These floors have held up to the test of time with little or no wear, little or no loss of shine and little to no yellowing even under the urinals. This is also available with an integral cove base

Solid Colored Flooring

These solid colored floors are based around self leveling, trowelable or double broadcast application techniques. These floors are sometimes called shop floor. They are made to be thick and extra durable under extremely harsh environments. They can be top coated with any of the systems above under coatings. This kind of flooring is available in 3 speeds of cure: normal, fast, and cold cure. Solid colored flooring is also available with an integral cove base.

Methyl Methacrylate (MMA) Flooring

The big advantage of MMA is speed of curing. Each coat of MMA will cure hard to the touch in 1-2 hours. This allows the next layer to be applied quickly and traffic to be returned to it quickly. You can even build a fast setting integral cove out of MMA resin.

I personally installed MMA on one kitchen floor with a very tight schedule. The restaurant was only closed for breakfast. The project started with rotten plywood floors. At 10 PM the carpenters came in to work. They removed rotten floor and floor joists. They replaced the floor joists and the plywood. At 5 AM I went in with my crew and we primed the floor and sealed up the joints in the wood and the screw holes. At 6:30 AM we laid the floor. At 8 we put a glaze coating on the floor and by 10:30 the restaurant workers were on the floor prepping for lunch. The floor installation from start to traffic took just 5.5 hours.

Polyurethane Decking Systems

Polyurethane Decking – http://www.epoxy.com/elastomeric.aspx – is the system best used in areas where maximum flexibility is necessary. This is typically outdoors, waterproof applications like balconies.

Specialized Flooring

We have a number of systems that are specialized flooring like conductive and ESD (Electrostatic Dissipative) flooring – www.epoxy.com/conductive.aspx – and various hybrid systems. If your project does not seem to fit in the categories above email me at norm@epoxy.com or call us at 352-533-2167.

 

In conclusion we offer many types of seamless flooring systems, they can be used for commercial and residential applications. These systems are durable, economical, and easy to install even by homeowners. These seamless flooring systems may be made out of epoxy, polyurethane, or methyl Methacrylate (MMA). Seamless flooring systems are available in multicolored or solid colored. They range in chemical resistance from very good to resistant to aggressive chemicals. When in doubt what is right for your project send me an email at norm@epoxy.com or give me a call at 352-533-2167.

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.
