Have a customer who is a nice lady but way wierd. She wants her 2 car garage concrete floor redone. I have mentioned several options such as the type of epoxies you use for garage floors and the different rubber tile systems. She wants something beautiful and suggested marble, slate, or travertine tile. I told you she was wierd. I told her that I usually sub out any tile jobs but she wants me to do it. For you tile guys, are any of these even remotely suitable for a garage floor. I already warned her that they would have to be textured so that they aren't slick when wet. The other question is will the tile crack or break? I assume they would due to the repeated weight of having cars parked on them. Any suggestions or advice would be helpful.
