Thanks, the floor has only been down for about 6 months now. It's Armstrong VCT tile, 12" square tiles that are grouped together in fours to make a 24" square block. This is the same tile you find in Walmart, grocery stores, etc. It takes a beating and is very durable, but the downside is that it is slippery when wet.
I thought about Racedeck and it's clones, paint, epoxy, oil-resistant carpet (the Griot's stuff), and the tiles.
Epoxy would be my preferred choice, but the good stuff would run about $2k for a 450ft^2 garage. The $200 paint and epoxy coatings just don't last longer than a few years - no matter how well you prep the surface from my experience.
Racedeck and the clones are pretty spendy too, but I don't like the thought of having fluids underneath and in-between my tiled floor. I guess you could take it with you if you move, but that would be a pain to pick up and clean off.
So, I settled on the VCT after reading about others experiences on

I filled in the expansion joints with flexible sealer, prepped the surface (must be smooth and acid-etched), and laid the tile. Just laying the tile by myself and rolling it took a full day. The prep work may or may not be hard depending on what you have to start with. It was a lot of work, but only cost me ~$400-500. This "should" last a long time, and if a tile gets damaged, just heat it up, scrape it out, and replace :wink:
Over the past 6 months, I've drug a lot of stuff over it, jacked up a few cars, and spilled a few types of chemicals on it. Oh, my NSX is a daily driver, and parking the hot tires on the floor have not discolored it (but I went with the gray and black tiles instead of traditional black and white to minimize potential discoloration).
Well, check out the link above. It's a good source of info with some pictures of really nice garages!
