Installing a new backsplash can completely transform the look of your kitchen or bathroom. However, if you already have existing tile that you don’t want to remove, you may be wondering if you can simply install a new backsplash right over the old tile. The short answer is yes, it is possible to put backsplash on top of existing tile. Here is what you need to know about adding a backsplash over tile.
Preparing the Existing Tile Surface
Before installing the new backsplash, you need to make sure the existing tile is properly prepared. Here are the key steps:
Clean the Tile Thoroughly
Use a strong degreaser to clean off any dirt, grease or soap scum on the existing tile. You want the surface to be completely free of any residues.
Check for Cracks or Damage
Examine the existing tile for any cracks, missing grout, or damage. Any major issues need to be repaired prior to installing the backsplash.
Rough Up the Surface
Use a sander or grinder to lightly scuff up the surface of the tile. This helps the new backsplash adhere properly.
Apply a Skim Coat if Necessary
If the existing tile is very uneven, you may need to spread a thin layer of mortar or spackle over it to create a more uniform surface for the backsplash. Allow any skim coat to fully cure as per the manufacturer’s directions.
Once the tile is cleaned, repaired, and roughed up, it should be ready for the new backsplash installation.
Choosing the Right Backsplash for Tile
You have lots of options when it comes to selecting a backsplash that will work over existing tile:
Ceramic, porcelain or natural stone tile are all great choices. Select a tile style and color that complements your existing tile while giving the space an updated look.
Metal backsplashes like copper, stainless steel or tin can install right over tile and provide a sleek, contemporary aesthetic.
Glass tile or sheet glass backsplashes are seamless and water-resistant, making them a smart choice for bathrooms and kitchens. They easily adhere over existing tile.
Slim stone slabs like quartzite, soapstone or granite can be applied over tile for a natural stone statement wall look.
For a warm, rustic accent wall, wood planks can affix to tile with construction adhesive. Use a waterproof wood species like teak or use pressure-treated boards.
No matter what material you choose, always select high-quality, durable products intended for backsplash use.
How to Install a Backsplash Over Tile
Installing a backsplash over existing tile is a relatively straightforward DIY project. Here is a general overview of the installation process:
Step 1: Prepare the Surface
Follow the steps above to ensure the tile surface is clean, repaired, roughened up and ready for the new backsplash.
Step 2: Plan Your Design
Map out the backsplash design and make any necessary cuts before you get started. Measure carefully to ensure the new backsplash fits properly.
Step 3: Apply Mortar or Adhesive
Spread a layer of thinset mortar or construction adhesive on the back of the backsplash pieces as well as on the surface of the existing tile.
Step 4: Set the Backsplash
Press the backsplash pieces firmly into place. Use spacers to maintain even grout lines. Allow the mortar or adhesive to fully cure.
Step 5: Grout if Necessary
For backsplash tiles, grout the joints according to manufacturer’s directions. Cleanup any excess grout.
Step 6: Seal and Finish
Apply any necessary sealers or finish coats based on the backsplash materials used. Caulk edges for a clean finish.
And that’s it! Take your time and make sure each step is done properly. Tiling over tile may take a little extra effort but can give older surfaces a brand new look.
