Before you start
Isolate and verify nearby electrical circuits before removing faceplates; never touch or tile over wiring. Use eye and skin protection for tile and cement products, and dust controls specified by the tool and material. No dry power cutting indoors. Resolve suspect old coatings before disturbance; do not disconnect gas appliances for this guide.
Tools and materials
- Ceramic tile, edge trim and spacers
- Compatible mortar, primer, grout, flexible sealant and caulking gun
- Tape measure, level and pencil
- Manual tile cutter and rubbing stone; suitable wet saw for notches
- Notched trowel, margin trowel and mixing bucket
- Rubber grout float, sponges and clean buckets
- Eye protection, suitable gloves, dust protection and counter covering
- Receptacle tester and screwdriver
Check the problem
Check the wall before covering it
Choose a dry, sound, flat wall with no loose coating, active leak or soft spots. Hold a straightedge across it to find humps and hollows. Repair the cause of damage first; this method does not cover tiling over an old backsplash.
Confirm the tile system and layout
Use glazed ceramic wall tile with mortar approved for both the tile and your wall. Measure each wall section, multiply height by width and add the areas. Allow about 10% extra tile for cuts and spares, more for an intricate layout.
Steps
Isolate nearby outlets and protect the counter
Switch off every circuit serving the work area and verify the outlets are dead with a suitable tester checked on a known live source before and after. Remove cover plates only. Leave devices and wires alone; arrange an electrician for box extensions or device repositioning. Cover the counter and sink.
Make a clean, flat bonding surface
Remove grease, residue and loose material using methods approved for the wall. Patch defects and let repairs dry. Apply the setting system’s specified primer where required, especially over gypsum patches. Do not sand old paint until lead risk is resolved.
Dry-fit rows before making cuts
Lay out tiles with the intended spacers. Shift the starting line to avoid narrow end slivers and plan cuts under cabinets. Mark level guides; do not assume the counter is level. Include the specified movement gaps at the counter, corners and cabinetry.
Cut and test-fit edge pieces
Mark each cut on the tile face. For straight cuts, score once with a suitable manual tile cutter, then snap using its breaker. Smooth sharp edges with a rubbing stone. Use a suitable wet saw for notches, following its manual; keep fingers clear and dry electrical connections protected.
Mix a small batch of mortar
Measure the specified water and powder. Mix, rest and remix exactly as directed, without adding water to revive setting mortar. Use the recommended trowel notch. Start with only enough mortar for an area you can tile within its working time.
Comb straight mortar ridges
Press mortar into the wall with the flat trowel edge, then comb parallel ridges with its notches. Work in small patches and keep movement joints clear. Remove and replace mortar that skins over rather than wetting its surface.
Seat the tiles and check coverage
Place tiles on the layout guides with spacers. Slide each across the ridges while pressing it in. Lift an early tile to check that the mortar transfers evenly and meets the product’s coverage requirement; adjust technique if needed. Keep faces aligned and joints clear.
Finish rows and leave them to set
Continue upward, checking level and spacing. Fit cut pieces around openings without obstructing electrical boxes or mounting holes. Add the planned edge trim. Clean stray mortar while soft, then leave the tiles undisturbed for the mortar’s specified pre-grout cure.
Fill the tile joints—not the corners
Remove spacers after the mortar has cured and clear debris. Mix compatible grout as directed. Work a small section at a time, packing joints with a rubber float and scraping excess diagonally. Leave perimeter and countertop gaps empty for flexible sealant.
Wash before the grout hardens on the face
Follow the grout’s cleaning window. Wipe with a well-wrung sponge, rinsing often; do not flood or hollow the joints. Remove remaining haze by the stated method and timing. Use a sealer only if the selected tile or grout requires it.
Seal the changes of plane and verify
Apply compatible flexible sealant at the counter, inside corners and required perimeter joints. Let grout and sealant cure before splashing or cleaning. Have any electrical adjustments completed and cover plates secured before power returns. Check for loose tiles, open grout gaps or breaks in the sealant.
Tiles remain firmly bonded, field joints are filled, perimeter sealant is continuous, and outlet covers sit securely with no exposed openings.
Tips
Test the finish on spare tile
A small grout test reveals scratching or staining before it affects the whole backsplash.
Keep the bottom joint flexible
Grout belongs between tiles; flexible sealant handles the countertop and corner transitions.
Plan outlet depth before tiling
Added tile thickness can leave a box recessed. Arrange suitable listed extensions and device support rather than improvising with loose spacers or screws.
