I installed a similar system iin my previous house in the Panhandle (Florida) and will never do it again. Looked great at first. But when you get it wet, the miosture gets under the tiles. Once that happens, mold/mildew grows. Still looked good, but ....
The other problem with these applications is thermal expansion . They grow and shrink as they heat up and cool. And with a heavy object (car/cart) you have sections buckle up.
Never again! Had my garage here epoxied, and have been very happy with it.
Just my opinion. Good luck!
