I surprised my parents by doing their garage floor while they were on vacation, this worked great. I had a prepainted floor, so I had to prep it a little extra with acid/etch, scrape any loose paint, then use Rustoleum garage and interior floor primer. The garage is approx. 19'x19' and covered very well with 2 kits. The Midnight Blue is very dark, so I added a little ultra fine blue glitter after rolling it on. I also applied the Rustoleum clear coat to help protect it. I used the non-slip sand that came with it, but it's more textured than I thought it would be and makes it a little harder to clean and wipe off dust. DTEP was great at shipping it out fast, so I had enough time to complete this last minute surprise before my parents got home, they love it.
