To paint marble tile you must employ specific preparation and application strategies to avoid a finish that will chip and peel. Because paint doesn't stick well to marble tile, you must abrade the surface to promote adhesion. In addition, instead of applying a standard acrylic latex floor paint, you should coat the surface with a specific type of primer and paint to obtain a durable finish capable of standing up to a large amount of duress.
Scrub the marble tile with soap. Rinse the surface thoroughly and allow it to dry before continuing.
Abrade the marble tile by sanding it. Load a palm sander with 200-grit sandpaper, and sand the tile in a circular, clockwise motion.
Cover areas you do not want painted with painter's tape.
Screw the roller frame into the extension pole, and slip a polyester roller cover onto the frame.
Apply a coat of oil-based primer to the marble tile, using the roller.
Allow the primer to dry for two hours.
Apply a coat of oil-based paint to the primed marble tile, using the roller loaded with a fresh, clean polyester roller cover.
