Epoxy is a type of resin, which then can harden and form polymer, something which sets it apart from other flooring materials. Since epoxy can be durable, many people assume that this makes it a stellar choice for garage floor coatings, since it is assumed that epoxy won’t crack easily. Epoxy can be quite durable, due to how the process of applying epoxy to concrete results in extreme hardening of the resin within it, making for a strengthened floor.
While it is acceptable to use epoxy for indoor surfaces, it’s not a good option for exterior concrete surfaces, due to the fact that epoxy is not UV resistant. This leads to the colors of your floor changing, the tans going yellow and the grays going green. If your garage has windows or you like to leave it open, epoxy is not the best choice for your garage floor coating.
People turn to epoxy garage floor coatings because they hear it is easy and cheap. The reality is that epoxy requires a more intensive installation process, with it taking anywhere from 5 to 8 days to complete the process, while other floor coatings can be done within the day. Epoxy comes with strong odors and VOC’s, meaning that you will need to protect yourself from the fumes while it cures.
Epoxy is also vulnerable to causing “hot tire pickup”, which is when your tires heat up from high temperatures or from driving. Epoxy is smooth, but it can also be slick. While epoxy can be durable, it’s not the best option for garages and other high traffic areas. It’s more prone to scratching, chipping, and other damages, and needs to be redone every 5-8 years, depending on how well you care for it.
