Epoxy floor coating boosts useful basement living space

Sometimes a good coat of paint can make a world of difference, and concrete basement floors are a case in point. If you’ve got an unfinished basement and you’re looking to create more indoor living space easily and inexpensively, then applying a coat of epoxy paint can help make that happen.

Sometimes a good coat of paint can make a world of difference, and concrete basement floors are a case in point. If you’ve got an unfinished basement and you’re looking to create more indoor living space easily and inexpensively, then applying a coat of epoxy paint can help make that happen.

Most basement floors in Canada are concrete, and as durable as this material is, concrete is usually pretty ugly when bare. Regular latex paint can make any basement floor look better for a while, but the problem is that it doesn’t usually last long. Latex paint is not made to take the traffic and abrasion you’ll find under foot, but epoxy is. It’s a type of paint made by different manufacturers, but it’s much more than just paint.

Epoxy is one example of how 1 + 1 = 3. True epoxies are all two-part propositions. Left alone, the two parts remain liquid indefinitely. But mix those two parts together thoroughly and it sets in motion a chemical reaction that causes the mixture to harden once and for all. You get more value than the sum of the parts.

You’re probably familiar with two-part epoxy glue. Epoxy floor paint is similar, just not as thick as glue. Another difference is the ratio of liquids that get mixed together. With 5-minute epoxy glue, it’s usually a 50/50 proposition. Mix equal parts of the two different pastes together, then apply the goo to whatever you need to fix, then wait. When the excess mixed glue has hardened on the piece of cardboard or scrap wood you used to mix on, then it has hardened on your repair, too.

Components of epoxy floor coatings are different. They’re not mixed 50/50, but rather most of the liquid is the paint, and a tiny amount of another kind of liquid is the hardener. Mix the two together thoroughly, let it sit in the can for a while, then roll the stuff on bare, clean, dry concrete.

The coating gets hard, not by solvent evaporation, but by a slow chemical reaction that makes the epoxy rock hard. But before you allow that to happen, there’s something else you’ll probably want to do.

Better appearance than paint is one of the claims to fame of epoxy floor coating, and this comes down to something called flakes. These thin, small, coloured bits of plastic come in a bag with many formulations of epoxy floor coating. They don’t look like much in the bag, but sprinkle them around evenly on wet epoxy and they harden in place and add a much nicer appearance. Flakes are especially effective if you have a floor that’s got dents, dings and imperfections. Flakes make the whole area look much more random, but in a supposed-to-look-that-way kind of way. It really works visually.

Sounds good, you say, but how do you sprinkle flakes when the entire floor is wet? Golf shoes. Since golf shoes have spikes on the bottom, they let you walk on the wet epoxy leaving only tiny marks where the spikes touched the concrete. If you get out there, spread those flakes, then get off the wet area ASAP after rolling on the initial coat, the epoxy will remain liquid enough for long enough that it will flow back and make the marks left by the spikes disappear.

I can’t vouch for the reliability of all formulations of epoxy floor paint, and in situations where flaking concrete is present on a floor, you will need to do some serious cleaning before application. Some epoxies even come with a special pre-treatment liquid to boost adhesion. I’ve had several experiences with Rust-Oleum epoxy paint and it has worked well and lasted for years.

Steve Maxwell is always amazed by the transformation of epoxy from liquid to solid. Learn all about making the most of your Canadian home at Steve’s website BaileyLineRoad.com.

The difference between coated and uncoated concrete is striking. One coat of epoxy is the fastest way to improve the appearance of any unfinished basement. (Photo by Steve Maxwell)
