Is there an epoxy based paint for ceramic tile?

An epoxy paint would not be the best choice when painting your existing ceramic tile. There are ceramic tile paints on the market or a high quality oil based paint would be the best to use.

A large amount of the work is in preparing the tiles to be painted. First step is to sand off the gloss finish existing on the tiles. This will ensure a rough surface for the preceeding coats of paint to bond to the tile. An orbital sander is a great tool for this stage. Thouroughly clean the surface and area.

Next you want to apply a high bonding oil primer over the entire surface. If you can see the tile finish after the first coat has dried ensure to apply a second coat of high bonding oil primer. Keep in mind you can have your primer tinted at the paint store to a couple shades lighter then the final color. Oil primer is the prefered choice due to the qualities of resisting water and fungus and mold growth.

Once the primer has been applied and allowed to thouroughly dry (24-48 hrs) you can begin with applying the final color choice. Apply as you did with the primer ensuring to allow sufficient drying times between coats. Expect to apply two coats of finish paint as the first coat, once dry, will show the misses. Apply a second coat.

Once the final coat of paint has been allowed to dry for at least 48 hours you want to apply two coats of clear urethane to seal the paint. Clear urethane provides protection for the paint and allows for easy clean up of the surface during household chores.
