Introduction
Installing a backsplash is a great way to add visual interest and protection to your kitchen or bathroom walls. If you already have existing tile that you don’t want to remove, you may be wondering if you can install a new backsplash right over the top. The short answer is yes, it is possible to put a backsplash over existing tile! However, there are some important considerations to keep in mind to ensure proper installation and adhesion.
Preparing the Existing Tile Surface
Before installing the new backsplash, the existing tile needs to be properly prepared. Here are the key steps:
Clean the Tile
Use a Tilex cleaner or other recommended tile cleaner to thoroughly clean the existing tile. This will remove any dirt, grease or soap scum that could interfere with proper adhesion.
Check for Cracks or Damage
Inspect the existing tile for any cracks, loose tiles, or grout damage. Any damaged or uneven areas need to be repaired prior to installing the backsplash. You may need to re-grout or replace any problem tiles.
Sand the Tile
Lightly sanding the existing tile will help rough up the surface so the new backsplash can adhere properly. Use a palm sander or sanding block with 100-150 grit sandpaper. Be careful not to sand too aggressively.
Apply Primer/Sealer
Applying a primer or sealer to the sanded tile will help the new backsplash bond properly. Look for a product designed for tile and follow the application instructions.
Choosing the Right Backsplash Materials
Not all backsplash materials are well-suited for direct application over existing tiles. Here are some good options:
Tile Backsplash
Ceramic, porcelain or natural stone tile are great choices for installing over existing tile. Use a high quality modified thinset mortar adhesive to attach the backsplash tiles. The mortar will bond to the sanded, primed tile surface.
Glass Tile
Glass tile can also be installed over existing tile backsplashes. Make sure to use a thinset designed for glass tile installation. The smooth surface of glass requires a mortar with extra adhesion properties.
Metal Backsplash
Metal backsplash panels, like copper or stainless steel, can adhere over existing tile if the surface is properly prepared. Use a premium silicone adhesive to attach metal panels. Silicone provides flexibility to prevent cracking or loosening.
Peel-and-Stick Backsplash
Adhesive “peel-and-stick” backsplash panels made from materials like metal or faux tile are an easy option for installing over tile. Ensure the existing surface is smooth so the adhesive backing will stick properly.
Installing the New Backsplash
Once you have addressed any issues with the existing tile and selected an appropriate backsplash material, it’s time to install. Be sure to follow all manufacturer’s instructions for surface prep and installation. Here are some tips:
- Prepare the backsplash materials – cut tile pieces, metal sheets, etc. to the desired size.
- Spread the thinset, mortar or adhesive evenly across the surface using a notched trowel.
- Press the backsplash pieces into place, using spacers to ensure even alignment and grout lines.
- Allow proper cure time for the mortar or adhesive before grouting or using the backsplash.
- Use a flexible, waterproof grout recommended for your specific backsplash material.
- Seal and protect the finished backsplash according to manufacturer recommendations.
FAQs
Can you put a tile backsplash directly over existing tile?
Yes, tile can adhere directly over existing tile backsplashes, provided the surface is properly prepared with cleaning, sanding and priming first. Be sure to use a quality thinset mortar recommended for installation over tile.
What about putting a backsplash over cracked or damaged tile?
Any cracked, missing or uneven tiles must be repaired and leveled out prior to installing the new backsplash. Damaged areas need to be smooth and stable for proper application of backsplash materials.
Should I take down the old backsplash instead?
It is not mandatory to remove existing tile before adding a backsplash. As long as the tile is in good condition and properly prepped, adhesion of the new backsplash should not be a problem. Taking down old tile is messy and time consuming.
Can I install a peel-and-stick backsplash over ceramic tile?
Yes, “peel-and-stick” backsplashes with adhesive backings can be applied over sanded and primed ceramic, porcelain or natural stone tiles. Ensure the tile surface is smooth so the adhesive will stick properly.
What about putting backsplash tile over existing glass tile?
Directly tiling over glass tile is not recommended, as the ultra-smooth glass surface will prevent proper thinset mortar adhesion. For glass tile, it’s best to remove and replace it with a more suitable subsurface before adding the new backsplash.
Conclusion
Installing a backsplash over existing tile or backsplash materials is certainly possible with proper preparation and by using the right products. With some cleaning, sanding, priming and careful installation, backsplash materials like tile, glass, metal and peel-and-stick panels can successfully adhere over existing tiles. Just be sure to address any damaged areas, use manufacturer recommended products, and allow proper curing time. With the right approach, you can refresh your backsplash without the hassle of tearing out your existing tile.
