You can paint ceramic tile flooring with oil-based paint. It will stand up to foot traffic for years with a final coat of clear urethane, just like the kind used on hardwood floors. Follow the directions below to freshen your ceramic tile floor with a great paint job.
Step 1: Diagram Your Tile Pattern for Painting
You may choose to paint your tiles in a checkerboard pattern, or with a contrasting border. Diagram the tile pattern for painting on a sheet of 1/4 inch graphing paper. If you are painting the whole floor a single color, you can skip this step. Purchase your paint according to the square floor footage of the room.
Step 2: Empty the Room and Open Windows for Ventilation
Remove all floor furnishings and rugs. Tape off all baseboards and doorways in the room with painter's green tape. Vacuum and sweep the ceramic tile floor. Open room windows and doors to allow for adequate ventilation while painting with oil-based paint, and to speed the curing of repaired tiles.
Step 3: Thoroughly Clean the Tile Surfaces
Use a spray bathroom cleaner recommended for tiles to clean and degrease the ceramic tile and grout. Apply it from the spray bottle and spread it over the floor with a sponge mop. Rinse out the mop with cool water and pass the mop over the floor surface again to rinse off dirt and excess cleaner solution.
Step 4: Repair Cracked and Chipped Tiles
Fix cracks and chips in tiles with tile grout and acrylic epoxy before painting. Allow the adhesives and grout to cure for 2 days, and check there is no "tacky" surface tension remaining. Once the surfaces are smooth to the touch you can paint them.
Step 5: Roughen the Tile Surface
Make 1 pass with the power sander fitted with a 220-grit sandpaper disk over the entire floor, then vacuum up all the dust. This will roughen the surface just enough so the oil or epoxy paint will adhere most effectively. Ensure you perform this step on glazed ceramic tiles. For unglazed tiles, this step is optional, depending on the reflectivity of the tiles.
Step 6: Apply Paint
If you are painting a pattern on your floor, apply the lightest color first with the natural bristle brushes, then the darkest colors. If you accidentally paint the wrong tile in a light color, the darker color will easily cover it. Use the four foot paint roller to apply a single color over the entire floor, including the grout lines. Allow the paint to dry for 48 hours to ensure it has adhered to the tile.
Step 7: Apply Urethane Sealer
Use the long-handled paint roller to apply water-based clear urethane sealer over the entire painted floor. The sealer will protect your paintwork and ensure years of vibrant, scratch-resistant color on your ceramic tile floor.
