Measure the area of your backsplash. Use a measuring tape to measure the dimensions of your backsplash area. Write these measurements down. Don’t worry about cabinet corners that cut into the backsplash area just yet. Masks are graded based on the size of particle they filter. Purchase one that will filter dust particles.
Transfer the measurements to your tile sheet. The easiest way to do this is with long strips of painter’s tape of masking tape. You can also draw on the back of the tile sheet with a marker. Be sure to mark any outlet and light switch holes. Place the sheet against the wall and mark them, if needed.
Put on some eye and respiratory protection, if needed. A pair of safety goggles is highly recommended because it will protect your eyes against flying pieces of tile. A good respiratory mask is only needed if you will be cutting the tiles with a wet saw or grinder. If you will be using tile nippers, you won’t need a mask.
Cut the tile sheet down to size with a box cutter. Flip the tile sheet over so that you can see the back, then cut through the mesh with a box cutter or utility knife. If the tape runs across a row of tiles, cut through the mesh along the inside edge of the tape. This will make your tile sheet a little smaller than necessary, but that’s okay.
If your tiles are staggered like bricks or a honeycomb, you will need to cut around the tiles. Don’t cut straight through them. Be sure to cut through the outlet and light switch holes. If your tiles are staggered like bricks, the gaps won’t be consistent. You will need to cut some tiles larger, and other tiles smaller.
