- Q. Can I install ceramic tile over a painted concrete floor without removing the paint?
A.Tile consultant Michael Byrne responds: Unless the paint in question is properly applied epoxy paint (not the kind that comes in a spray can), you shouldn’t install ceramic tiles over either paint or paint overspray. If tiles are installed over a painted floor, the bond strength of the tile adhesive will not be any stronger than the paint’s grip on the concrete.
