The Difference of the Right System
Coatings come in all kinds of quality levels, starting at the “Do-It-Yourself” grade found at the big box stores to commercial grade products installed by professional coating contractors.
Epoxy floor coatings are designed to be a sacrificial barrier between the concrete substrate and the elements in your garage that are harmful to it (i.e. tire traffic, road salt, gasoline and oil leaks, etc.) the thicker the coating the longer your protection barrier will last. Typical epoxy kits sold at Big Box stores will have a film thickness of approximately 1.5 mils per coat versus a professional grade product with a thickness anywhere from 3.0 – 30.0 mils per coat, at least double the film thickness.
The difference in thickness has to do with the volume solids in the can. The more solids by volume your coating contains, the thicker the final coating will be. Professional grade products will contain anywhere from 65%-100% solids by volume, providing a much thicker coating for your protective surface.
