Steve,
How has the sealer held up to oil drops? Are you still happy with the results? I'm thinking this might be the way to go for my garage, lots of tire turning to get in-out (I'm afraid the epoxy paints would peel up from this action). I also like the look of a glossy concrete floor...very industrial!
One more question, how slippery is it when wet?
The one 12' X 14' room I have used it in doesn't have any car traffic only a heavily loaded lumber cart with steel wheels that gets moved around without any problem for the sealer. The sealer is oil proof, water proof and dust proof (sweeps up easy without concrete dusting) - that's all I wanted for my very smooth cement floor. I have drained my compressor (located in that room) on it and wiped up the oil and water, no problem. I'm happy with it as I said before and will seal the rest of my shop using it when I get the time to do so. I sealed another room (lathe and mill room) with another Thompson product that was petroleum based but in hind sight I wish I had used this water based sealer instead. It's not a big deal they both keep oil from penetrating which leads to a dingy looking floor when dirt is combined with the oil. I put down the third coat out of curosity to see how glossy it might get but will use only two applications in the rest of the shop.
SLIPPERY? My floor is very smooth, so is ice and I learned to walk on it at a very early age and haven't forgotten how so I have no problem. The sealer doesn't pose any additional problems I've noticed. I heat my shop full time in the winter so anytime I step into it and onto the warm floor with snow on my shoes there is the potential to slip so I have a non-skid mat at that location to wipe the snow off.
BTW, I bought this product ~5 years ago and was told recently by another that they couldn't find it, maybe it isn't even available anymore. Have you found it available where you are?
