How to Install a Kitchen Backsplash: Step-by-Step
A kitchen backsplash transforms the look of your kitchen in a weekend. Professional installation costs $400–$1,200. DIY costs $80–$400 in materials plus a weekend of your time.
Materials Needed
- Tiles (subway, mosaic, peel-and-stick, etc.)
- Tile adhesive or mastic
- Grout (sanded or unsanded depending on tile spacing)
- Notched trowel
- Tile spacers
- Grout float
- Wet tile saw or tile cutter
- Sealer (for natural stone)
Step 1: Prep the Wall
Clean the wall thoroughly. Remove outlet covers. Mark a level horizontal line where you want the bottom row to sit — typically 1/8 inch above the countertop to allow for grout.
Step 2: Apply Tile Adhesive
Spread adhesive with the notched trowel in a 3–4 sq ft area. Hold the trowel at 45 degrees to create ridges that help tiles adhere. Work in small sections so adhesive doesn\’t dry before tiles are set.
Step 3: Set the Tiles
Press tiles firmly into the adhesive with a slight twisting motion. Insert spacers between tiles for even grout lines. Check for level frequently. Cut tiles as needed for outlets and edges using a tile cutter or wet saw.
Step 4: Apply Grout
After adhesive cures (24 hours), remove spacers. Apply grout diagonally with a float, pressing it into the joints. Remove excess with a damp sponge in circular motions. Wipe haze with a dry cloth after 30–60 minutes.
Step 5: Seal and Finish
Apply caulk (matching grout color) where backsplash meets countertop — this joint must remain flexible. For natural stone, apply sealer. Reinstall outlet covers.
