I love my Racedeck, and it gets high compliments from just about every customer that walks in the door. I've been open around 3 months now, and if I want it to look like it did 2 months ago, I'll probably be replacing a couple hundred tiles every 6 months or so. Even with a blanket down, grinding sparks find their way to bare tiles, where they melt into it as they cool. Overspray finds them too. While the overspray CAN be cleaned with acetone or carb/brake cleaner, it's pretty cost prohibitive.
I really only have 2 complaints. 1-The expanding/hoving that the tiles do when it gets hot, or I have the door open, allowing the sun to hit them. (I'm putting in a/c, so it shouldn't be much of an issue much longer) 2-Since I have a mostly flat floor, I do have a few "puddle" spots. If I sit or put my knee down in one of those spots, the water wicks right into my clothing. I've debated putting some drainage cuts towards my floor drain to help eliminate the standing water under the tile. If my floor was sloped a little, I'm sure it would be a non issue. It takes around 3-5 days for it all to dry out - but it's mopped just about daily M-F.
My daughter does good with her first paying job - sweeping, scrubbing, and mopping the floor every night. I've found that it works best to use a deck brush with degreaser first, squeegee off, then the best finish has come from Mop-N-Glo. The undamaged tiles look like new. Until the next day when the abuse starts all over lol.
