Wear a dust mask and disposable gloves throughout the cleaning and painting process.
Scrub the table with tile cleaner or some sort of heavy duty cleaner to remove all residue.
Gently sand the tile surface to remove any grout or film.
Apply acetone to a sponge, soft cloth or paper towel, and wipe down the table to remove any remaining grit or soap residue.
Tape plastic sheeting to the sides of the table to prevent paint from splattering on the table base.
Decide what kind of pattern, if any, you would like on your table.
Measure the table, and fit your pattern to the tabletop.
Tape off any parts of the tabletop that you want to remain the original color. If you wish to have the grout remain unpainted, tape off the grout lines.
Apply high-adhesion primer to the exposed parts of the ceramic tile. Allow the primer to dry for a minimum of three hours. Do not expose the table to moisture or dust during this time.
Paint on your design with a sponge brush and epoxy paint. If you wish to use more than one color, either fill in different areas with different colors or re-mask different areas once the first coat of paint has dried fully.
Let the ceramic tile dry for 24 hours. Do not expose the tabletop to moisture during this time.
Carefully peel away the tape from the design. If necessary, run a mat knife at the edge of the tape to break its seal with the paint.
Remove the plastic sheeting from the table edge.
Wash the tabletop with a non-abrasive cleaner.
