While porcelain tile boasts exceptional durability, there are few products and techniques you should take pains to avoid: 1  Never use a product containing ammonia or bleach (or any type of acid-based cleanser); these can alter the tile color and/or stain the grout. 2  Never use oil-based detergents or wax cleaners.

If the paint comes loose, so does the tile. You should either strip or bead blast the concrete and thoroughly clean it.
