Whenever you first realize that your epoxy garage floor paint has begun to peel, your initial reaction may be to place blame to the product itself. I mean, if the coating is tarnishing, then it has to be some cheap, ripoff product, correct? Well, not necessarily so. In truth, this “cheap” and “inferior” floor coating normally won’t peel, dull, crack or even wear away. Most likely, if your garage flooring is having a peeling problem, it is more of a moisture problem.

Epoxy Garage Floor Paint Keeps Moisture Out…And In.

Epoxy will definitely insure the protect of your garage floor’s concrete from moisture and humidity in air, but doesn’t have any defense against moisture from under. Epoxy is made to have a seal-like ability that is able to prevent moisture from most origins from penetrating through, almost completely. For example, if oil were to drip on the garage flooring, it would not be able to penetrate through the epoxy paint, and as a result the concrete will not have absorbed it and can just be cleaned up.

Concrete Absorbs Liquids

Since the concrete for your garage floor sits underground, both its sides and bottom are able to absorb any liquids that they find there. Even if something were to somehow get to the concrete there to stain it, you’d never see the actual stain, so the primary worry is water. Unfortunately, this water that is absorbed into the concrete must evaporate. That wonderful epoxy garage floor seal suddenly becomes its own worst enemy. It’s a dual edged sword: it will keep the moisture in just as it keeps moisture out. As the water rises through the concrete, it begins to create bubbles under the garage floor paint. As the bubbles expand, they will eventually burst, causing the dreaded epoxy paint peeling.

Epoxy Garage Floor Paint Does Not Get Along With Humidity

Some issues related to your area can cause this peeling effect. Humidity, for one, can play a big role. In humid areas, everything, including the earth itself, will stay moist for quite a while after rains. This creates a large area from which the concrete will draw water. The situation is even worse if water is able to pool against the concrete in any way.

Ground Water Is Water, Too

The height of the local water table can also affect garage floor paint. The water table is, put very simply (and not entirely correctly), the top of the ground water. If the water table is high, then the ground water sits close to the bottom of your concrete garage floor, which means water is far more likely to soak through. Does your area’s soil stay somewhat moist, even when in a drought? Odds are pretty good that the water table sits high.
