i've used rustoleum's product in two garages. the curent one's about 3 years into it and the only areas it's chipping is where we dropped a heavy piece of metal. It's a heavily used garage. We've got a project car. And we're constantly spilling fluids, roiling our 600lb table saw back and forth, etc. It is all about the prep. We acid etched and waited a really long *** time for it to completely dry. I have a humidity meter that I used on the ground to check from dryness. Didn't use the chips as we found out the hard way in our previous home the chips don't really give good grip so this time around we used sand.
