Epoxies are two part paints that are known for toughness but will usually yellow quickly in sunlight. They can seal wood, cement, concrete, or metal surfaces and serve as a floor coating or undercoat under other paints, tiles, or wood surfaces. The two parts of the epoxy kit are mixed together and then applied to the surface. The working time between mixing the epoxies and when it begins to set is based upon temperature, the amount of epoxy mixed, and the kind of epoxies. Many common epoxies may only have a working time of 15 to 30 minutes per batch under many circumstances. Most epoxy floors are applied by paint roller. Some professionally applied floors are sprayed or trawled down.


Problems that may be encountered with epoxy floors (and also their application) include:

1) the yellowing of the epoxy in sunlight (mentioned above);

2) the short working time of many epoxies;

3) air coming out of concrete surfaces and forming bubbles/blisters in thick epoxies that are just beginning to harden;

4) areas of the floor that remain sticky (a sign of poor or incorrect mixing of the two part epoxy);

5) the epoxy not sticking or being pulled up by hot tires etc. (this is related to the surface itself and its preparation prior to coating. It is not related to the epoxy itself);

6) no ‘sure thing’ preparation method — lots of preparation options available. You have to make some personal decisions on what kind and how much preparation is enough and then cross your fingers. You will not know until the coatings have been down for some time if the surface preparation was ‘good enough.’ In some cases the cement/concrete is in such bad conditional that no amount of surface preparation will be enough to keep the epoxy coatings adhered to the floor.;

7) moisture/water issues within the cement/concrete can also cause epoxy (and other floor coatings) to fail/lift off. True professionals know which jobs not to bid on and not to get involved with.

8) unknown to you, past owners could have put something like the wax based Thompson Water Seal ™ on the concrete. No way to remove this and nothing will stick to it for long (best to do a test spot first).

If you decide to add ‘grit’ for anti slip purposes, this also introduces more options for you to consider. There are different kinds of grits, different sizes of grits, different methods of applying the grit, and different personal opinions regarding how much grit to use.

Water Based Epoxy Floor coatings — a thin coating that is easy to apply and work with, but hides nothing and is not the ‘commercial’ epoxy floor most people think of.

Solvent Based Epoxy Floor coatings — Sort of like an oil based enamel, these epoxies contain solvents. These kinds of epoxies are generally not very common any more.

Solvent Free Epoxy Floor coatings — The classic epoxy floor — thick enough to hide many floor flaws. Short working time per batch. Usually no odor.

In a multi coat system, a combination of the above epoxy types might be used as well as some non epoxy coatings (to provide UV protection to the epoxies, reducing yellowing).

Note that sometimes a thin water based or thin solvent based epoxy can/will be used as a sealer or base coat on concrete/cement under the ‘regular’ epoxy floor coating.


While the above information sounds daunting, most homeowners successfully get away with minimal surface preparation and one or two coats of epoxy ‘slapped’ on to the surface.
