My three car garage has several unsightly areas where efflorescence is blooming out of the concrete floor. I have power-washed the whole floor but that only increased the efflorescence after the water dried. The efflorescence is particular bad after I bring a car in from the rain and the rain water dribbles on the floor.
I know that this problem is only cosmetic but a prospective buyer might be concerned. I also understand that painting the floor or covering it with epoxy is counter productive because it will only spall and will therefore be more unsightly than the efflorescence.
Can I cover the concrete with a material that does not try to bond with the concrete? Something that can be laid on the top of the concrete? Ceramic tiles? Is thin-set impervious to efflorescence? Vinyl tiles?
Would appreciate any suggestions? Thank you
Walter
