Finished tiled splashback with neat grout, socket refitted, sponge and grout float
Safety note: Wall tiling involves sharp tile edges, adhesive dust, wet surfaces and work near sockets. Isolate power before loosening faceplates, keep adhesive and grout away from electrics, and use a qualified electrician if a socket, cable or back box needs moving or repair.

1. Set out before adhesive is mixed

Wall tiling stage 1 with layout lines, tile samples, level and protected worktop

Clean and prime the wall if required, then mark a level reference line. Dry-lay a row of tiles with spacers so narrow slivers do not end up in obvious corners. Protect worktops, cabinets and sinks before opening adhesive.

2. Comb adhesive and build from a straight line

Wall tiling stage 2 with first rows of tiles, adhesive, spacers and tile cutter

Spread only as much adhesive as you can tile before it skins over. Hold the notched trowel at a consistent angle, press tiles in with spacers, and check the first rows often. Small errors multiply quickly across a splashback.

3. Leave awkward cuts until the field is stable

Measure edge cuts individually rather than assuming the wall is square. Around sockets, isolate power and loosen faceplates only if you are competent to do so. Keep cuts neat enough that the faceplate covers tile edges without being forced.

4. Grout, clean and seal movement edges

Remove spacers once adhesive has cured, then grout diagonally across the joints. Wipe haze before it hardens and finish the worktop edge with sanitary silicone rather than rigid grout. Refit faceplates only when the area is clean and dry.
