A tile backsplash is a high-impact, beginner-friendly upgrade that transforms a kitchen for a modest cost. The keys are a clean surface, a good layout, and patience with the grout.
Prep the wall
Clean the wall of grease, turn off and remove outlet covers, and lightly sand glossy paint so the adhesive grips. Plan your layout from a centre line so cuts at the ends are balanced, and dry-lay a row to check.
Set the tile
Spread tile adhesive (mastic or thinset) with a notched trowel, press tiles in with spacers for even gaps, and work in sections. Cut tiles to fit at edges and around outlets with a tile cutter or wet saw. Check tiles are level and flat as you go.
Grout and finish
Once the adhesive cures, grout the joints, wipe off the haze, and let it cure. Seal cement-based grout, and caulk where the backsplash meets the counter (caulk, not grout, handles that moving joint). Reinstall outlet covers with spacers if needed.
