I'm restoring a Victorian home that has original white honeycomb tile in master bath that appears to be in good shape except for needing major cleaning. My 1st choice would be to try to paint it (maybe a dark/navy blue) and then put a glaze over it. [I'm concerned that installing new floor tile may be a problem because the added material could impact the leveling of all the pipes for the clawfoot tub, ceiling showercurtain, etc.] Is it possible to paint and/or glaze an existing floor tile in a home?
