Concrete must be allowed to breath moisture and Racedeck allows it to do that...coatings normally do not allow moisture to escape and that's when delamination occurs if there is a buildup of moisture. Racedeck was designed with an air chamber underneath it to allow whatever moisture may accumulate under it (whether it came from the top or the bottom) to disipate.
I rebuilt my Cobra on top of RaceDeck over the period of about a year and I spilled alot of liquids. When the car was completed, I pulled the floor out to clean it and what did get between the joints I was able to clean up with just 2 paper towels.
I have seen concrete garage floors that were so wet with moisture coming up thru the foundation that Epoxy contractors walked away from them for fear of failure. We had RaceDeck installed instead and there has been no complaint or problems.
Also, how many epoxy floor coatings have you seen that can be removed and installed in another location if you happen to move?
