How to Tile a backsplash

Tiling a backsplash involves measuring and marking your layout, cutting tiles to fit, applying adhesive, installing tiles with spacers, then grouting and sealing the finished surface.

1. Plan your layout and gather materials. Measure your backsplash area and calculate tile quantities, adding 10% extra for cuts and mistakes. Choose your tiles, adhesive, grout, and spacers. Remove outlet covers and switch plates. Clean the wall thoroughly with degreasing cleaner to ensure proper adhesion.
2. Mark your starting point and reference lines. Find the center point of your backsplash and mark a vertical line using a level. This prevents ending with tiny tile slivers at corners. For areas behind stoves or sinks, center the layout on these focal points. Mark horizontal lines to ensure straight rows.
3. Cut tiles to size. Measure and mark tiles that need cutting around outlets, edges, or corners. Use a wet saw for straight cuts and a tile nipper for small notches. Always wear safety glasses. Test-fit cut tiles before proceeding to ensure proper spacing around obstacles.
4. Apply tile adhesive. Spread adhesive with a notched trowel, working in small sections about 3 feet wide. Hold the trowel at a 45-degree angle to create even ridges. Only apply as much adhesive as you can tile in 15-20 minutes to prevent it from skinning over.
5. Install the tiles. Start at your center line and work outward. Press each tile firmly with a slight twisting motion. Insert spacers at each corner to maintain consistent gaps. Use a level frequently to check that rows remain straight. Remove excess adhesive from joints immediately.
6. Complete edge treatments. Install cut tiles around outlets and edges last. For outside corners, use bullnose tiles or trim pieces for a finished look. Make precise cuts for tight fits around electrical boxes, leaving just enough room for outlet covers to sit flat against the tile.
7. Remove spacers and clean excess adhesive. Wait 24 hours for adhesive to cure, then carefully remove all spacers with needle-nose pliers. Scrape out any adhesive that squeezed into grout lines using a utility knife. Clean tile surfaces with a damp cloth before grouting.
8. Apply grout and finish. Mix grout according to package directions. Apply with a rubber float, pressing firmly to fill all joints completely. Work diagonally across tiles to avoid pulling grout from joints. Clean excess grout from tile faces with a barely damp sponge, rinsing frequently. Allow to cure, then apply grout sealer if recommended.
