Can the tiles be sealed to prevent turning darker from water?


Glaze Absorbs - We have installed ceramic tile that absorbs water from the glazed side of the tile and the tiles turn a darker shade from the penetration of water. Can the tiles be sealed to prevent this problem and what is the cause?


ANSWER - Although most glazed ceramic tiles are impervious, there are some that are absorbing to some degree. You can apply a sealer to the glaze by using one of the products from a sealer company (see Cleaners and Sealers for names of sealing manufacturers). The sealer may temporarily solve the problem or may only help to some degree. It will be important that you keep don't let water sit on the tile for extended periods of time and that you reseal it every 6 months or so. Good Luck!
