I used some on my driveway outside a few months back. I was going to do my garage floor but was concerned about traction. Apparently when this stuff first came out some people had trouble coming into their garage during the rain and had trouble stopping . I didn't want to had the sand or whatever it was they offered to mix with it to give better traction.Kinda defeated the purpose of making the floor easier to clean with a grainy surface. Anyway I had a second driveway poured and it was kinda crappy and porous big time. So I bought a couple kits and rollered it on. I like it. It smoothed the driveway out and little oil or other spots clean right up. . I tried to make my car slide one rainy day and I really had to push it to make it happen so I don't think it's as dangerous as someone would think.Might do my garage after all.
My 2 cents.
