You’ve probably heard the warnings: Epoxy turns yellow in sunlight. It flakes off the floor. It’s just not a great option.

And you know what? Those statements are true. But when people say these things, they’re talking about DIY epoxy garage floor kits, not professionally installed systems. Making a blanket statement like “epoxy is bad” is a bit like saying, “My computer crashed, so all computers are unreliable.” It’s misleading and ignores the critical differences in quality, preparation, and performance.

Let’s start with the first—and arguably most important—difference between DIY kits and professional epoxy floors:

Concrete Preparation: The Foundation of a Lasting Floor

Always Grind the Concrete
DIY kits typically include a small bag of acid that you mix with water to “prep” the surface. But acid washing just doesn’t cut it. Some people claim, “Grinding is outdated—acid washing is the modern method.” That’s simply not true.

Here’s why acid washing fails:

  • It doesn’t make the surface rough enough for epoxy to bond properly.
  • Most garage floors have a sealer—a plastic-like layer that prevents acid from reacting with the concrete.
  • If the acid can’t penetrate, it can’t prep. So, in many cases, it does absolutely nothing.

Grinding, on the other hand, removes sealers, opens the pores of the concrete, and creates the ideal surface profile for epoxy adhesion.
