One note of caution concerning garage floors. I used Rustoleum's epoxyshield product several years ago. It looked nice and all, but when that sucker got a little water on it, it was like walking on an ice rink. After a rain or during the winter months, those slick spots were brutal.
I ended up picking up some diamond rubber flooring from Costco. It cleans up nicely, looks good and is textured to avoid a case of premature death. It's not the cheapest option out there (I think I ended up using two rolls @ $180-$190 at the time for my two cars garage), but it has held up nicely.
This is VERY true.
What we did was .
Use a lot heavier coverage of chips, This gave more texture.
Plus we ordered a silica grit, to mix in with the clear topcoat, as we applied the top coat.
Problem mostly solved. You could probably slip on the surface if wet, however its not really slick, even when wet.
Note. A lot of the "big box" epoxy kits do not have a clear topcoat.
Topcoat really helps with overall durability, plus you can add grit to it.
Plus it looks better!
