How to Install a Tile Backsplash (The Easy Way)

Time needed: 4 hours

Learn how to install a tile backsplash following these simple steps!

1. Prepare the Walls for Tile

   First you want to clear the space. Then you need to do any wall repair that is needed (repairing holes or gouges in your drywall, etc). Once any repairs are done, be sure to clean your walls well. If you have any outlets in the backsplash area, be sure to turn the power to those outlets off. Remove any outlet covers and switch plates in the area to be tiled. Then protect/tape your countertop, cabinets, etc. that you don't want to accidentally get grout on.
   
   Our wall looked a bit weird since I had previously painted a design on the wall, but you can see I did some minor drywall repair below the upper cabinet we installed.
   
   

2. Check for Level and Install a Ledger Board if Needed

   Our countertop was perfectly level–yay! If it is not, you will want to draw a level line OR attach a ledger board (a fancy term for a thin strip of wood) to the wall. The ledger board will temporarily support your backsplash tile until everything cures. If you are installing backsplash tile in an areas where there is no countertop (like behind appliances), you will need a ledger board to keep your tile level and supported.

3. Plan Your Tile Layout

   Carefully measure the length and width of your backsplash area. We then drew out that area on a piece of scrap wood. Find the center of the area and mark a vertical line since many tile patterns (like ours) look best when centered. Then, dry lay your design to make sure everything will fit properly. This is important because you don't want to be left with tiny slivers of tile anywhere.
   
   Start by dry-laying your tile vertically (be sure to use the spacers you have chosen to use). Confirm that your vertical layout will work without leaving any tiles that are too small/thin.
   
   Next, dry lay your tile horizontally (again, be sure to use your spacers) and check the ends. If any pieces would need to be cut too narrow, adjust your layout.

4. Apply Adhesive to the Wall

   Once you are confident in the layout of your tile backsplash, you are ready to apply to your tile adhesive. You can use thinset or mortar, but I prefer using MusselBound tile adhesive mat. We have used it several times now (for our fireplace makeover and for this DIY tile headboard) and it's so much less messy than thinset! The only downside of the MusselBound tile adhesive mat is that you cannot “scoot” or slide tiles around once they touch the mat. And the adhesive is STRONG. If you misplace a tile, you have to pry it off, which isn't super easy. But even with that in mind, I strongly prefer using it over messy thinset (which we have also used many, many times).
   
   If you decide to use MusselBound tile adhesive mat, cut it to size and stick it on your wall. Use a utility knife to cut out around any obstacles like outlets or light switches.
   
   

5. Install Your First Row of Tiles

   Peel the protective paper off your MusselBound tile adhesive mat. Then press your first piece of tile into place, being sure to leave a 1/8-inch expansion gap where it meets your countertop. We started from the center and worked our way out. Even though I had confirmed our countertop was level and was using it as my guide, I checked for level constantly as I worked on the first row. If your first row isn't level, your entire tile backsplash will end up being wonky.
   
   

6. Install the Rest of Your Tiles

   Keep placing your tiles using spacers to ensure perfectly even spacing. I placed all of the full tiles first. Then we measured and marked each tile that needed to be cut. We have a wet saw, but you can absolutely use a manual tile cutter and/or nippers to cut tile. The tile saw is by far the least scary saw in all the world, which is why I'm comfortable using it.
   
   

7. Apply Your Grout

   I highly recommend pre-mixed and pre-sealed grout that eliminates the need for a separate grout sealer. It makes it so easy! Grouting is messy, but it isn't difficult. Use a rubber float to apply your grout into all the joints. Hold your rubber float at a 45 degree angle as you work. Make sure to fill all of the tile joints/grout lines fully.
   
   

8. Clean and Dehaze Your Tile

   After you have grouted, follow the manufacturer's instructions for whatever grout you are using and wait the recommended amount of time before wiping away any excess group with a damp sponge. Be sure to rinse your sponge often as you do this! Once all the excess grout is cleaned off, let your grout dry for a while (again, the instructions on your grout should specify how long) before giving your tile a final cleaning. You may noticed that your tiles look a little hazy before your final cleaning. If you accidentally wait too long to wipe the haze off, you might need to purchase a haze remover.
   
   

9. Install and Outlet Extender & Replace Outlet Covers, etc.

   Be sure to add box extenders to your outlets and/or switches to ensure they sit level with your new tile backsplash. Then replace your outlet and/or switch covers.
   
   
   
   I bought a paintable outlet cover and painted it to match our backsplash tiles so that it would blend in and not stick out like a sore thumb. So easy.
   
   

10. Caulk Your Joints

    Last but not least, you need to caulk the gap/joint between your countertop and tile backsplash. I also like to caulk between the backsplash and any wall corners.
