Ceramic bathroom tile is considered to be a durable and long lasting finishing material. However, bathroom accessories and fixtures are usually drilled on previously untouched surfaces, creating unsightly holes that ruin the overall look of the finish. It is easy to repair a hole in a ceramic bathroom tile and all you need are simple materials that can be purchased at any hardware store.

Step 1 - Prepare the Hole

Check out bathroom tiles on Amazon.

Inspect the holes and remove any debris that may hinder the bond between the filler of choice and tiles. Use a vacuum cleaner or pressurized air to remove any dirt that may remain inside.

Step 2 - Apply the Filler of Choice

Auto body repair filler is the preferred material of choice for covering holes in ceramic bathroom tiles, but you can also use silicone caulk or pre-mixed grout to cover them.

When deciding to use auto body repair filler, it is best to follow the instructions stated on the packaging. Mix the resin with the hardener until you achieve a smooth, even consistency, and apply immediately using a putty knife. You may also use pre-mixed auto body repair filler to take the guesswork out of the mixing process. Place some into the holes and press firmly with the putty knife to ensure the material completely fills the cavity. Let it dry for a few minutes until a rubbery consistency is achieved. Then, scrape off excess material using a putty knife or razor blade. You may need to sand the area to achieve smooth coverage.

When using silicone caulk, it is best to use one that is the same color as the tile. Attach the cartridge to a caulk gun and press the trigger firmly to dispense some into the holes. Press on the hole firmly with a putty knife and wipe off excess caulk using a wet sponge. Then, let it dry. The same procedure applies when using pre-mixed tile grout. Fill the hole with grout with a putty knife and wipe off any excess with a wet sponge. You can also buy this material in the same color as the tile.

Step 3 - Clean Up

Remember that auto body repair filler can prove extremely difficult to remove when completely dry. Sanding the surface is the only way to remove any excess. Any drops or spills of silicone caulk and pre-mixed grout should also be immediately removed from the before the mixture gets a chance to dry.

Bathroom fixtures and accessories that come with suction cups will negate the need for drilled holes in your ceramic tile, so make sure to look for these types instead of those that secure with screws. This way, you never have to worry about going through repairs again.

WARNING: Don't forget to wear a face mask and safety goggles while sanding to avoid getting particles in your body. If the filler has toxic chemicals in it, wear the mask while applying it as well and make sure the work area is ventilated before you start.
