A Beginner's Guide to Tiling a Splashback

Why a Splashback Is a Brilliant First Tiling Job

A splashback is the ideal place to learn to tile. It is small, mostly flat, and rarely more than 600mm high, so you can see the whole job at once and finish it in a weekend. It also hides a multitude of sins behind a neat, wipeable surface that will shrug off steam, grease and the odd splash of bolognese.

Before you start, gather everything: a spirit level long enough to span the width, a notched trowel, a tile cutter (a manual rail cutter is fine for ceramics), tile spacers, a rubber grout float, a sponger, a bucket, a pencil, and a cloth. Add a dust sheet, some masking tape and a couple of old towels you do not love.

• Tiles — ceramic is forgiving and easy to cut; porcelain is tougher but more hardwearing.
• Adhesive — powdered cement-based for most jobs, ready-mixed for small ceramic areas.
• Grout — fine-grained, mould-resistant, in a colour you can live with.
• Silicone sealant — for the joint along the worktop and any vertical corners.

Preparing the Wall Properly

Most failed splashbacks fail because of poor preparation, not poor tiling. Strip any old tiles, then scrape off every trace of adhesive with a wide scraper or a wallpaper steamer to soften it. Fill dents and gouges with a fine filler, and sand the whole area flat once dry. Wash the wall down with a degreaser or hot soapy water to remove cooking residue.

Check what you are tiling onto. Bare plaster and plasterboard can carry roughly 20kg and 32kg per square metre respectively, and most kitchen tiles sit comfortably under that — but if you are using heavy stone, fix a tile backer board instead. For a very uneven wall, a thin coat of levelling compound saves hours of fiddling with adhesive thickness.

If the surface is dusty or porous, brush on an acrylic bonding primer and let it dry. Avoid PVA — it is a common shortcut that can stop modern cement-based adhesive from gripping properly.

Finish by holding a tile against the wall in a few spots to check for rocking. Any obvious hollows are worth filling now rather than fighting later.

Choosing the Right Adhesive and Grout

For a standard ceramic splashback on a sound wall, a ready-mixed adhesive is quick and perfectly adequate. If you are working with porcelain, large-format tiles, or the wall behind a hob or range cooker, use a powdered cement-based adhesive and mix it to the consistency of thick double cream. Near a heat source, choose one rated for the job rather than assuming.

Grout matters more than people expect. In a kitchen it will see steam and grease daily, so pick a fine-grained, mould-resistant grout in a mid-tone if you want to disguise marks. Wide joints in a busy kitchen become grubby quickly, so keep the joints to 2–3mm unless the tiles are designed to be butted together.

Match the silicone to your grout rather than to the tile — a colour-matched sealant along the worktop looks far more considered than a bright white bead.

Setting Out Before You Stick a Single Tile

Never start tiling from a corner. Corners in period homes are rarely square, and a strip of tiles along one edge will betray every millimetre of that. Instead, find the centre of your most visible feature — usually the middle of the hob or the window — and work outwards from there.

Measure the width, then divide by the tile width plus one spacer to see how many full tiles you get and what cut you are left with at each end. If the answer is a sliver of 20mm, shift your centre line by half a tile so you finish with two even cuts. Dry-lay a row along the worktop to check before committing.

Draw a level line across the wall at the top of your first full row, using a spirit level and pencil. On a long splashback, a laser level speeds this up considerably. If the worktop is not level — and in older houses it often is not — the eye will forgive a slight taper at the bottom far more readily than the top edge wandering.

Fixing the Tiles and Cutting Neatly

Spread adhesive with the flat side of the trowel first to key it into the wall, then comb it with the notched side in straight, even strokes. Work in sections no bigger than a square metre so the adhesive does not skin over. Press each tile on with a slight twist, adding a thin layer of adhesive to the back of larger tiles for full coverage.

Use spacers, and check every few tiles with your level both ways. Around sockets, isolate the power first, loosen the faceplate, and cut the tile so it sits behind it. A manual cutter handles straight cuts; for awkward shapes around pipes or a curved edge, use a tile nibbler and finish with a diamond file. Always file cut edges so they do not catch a cloth later.

Leave a 2mm gap at the worktop and at any external edge. This is not laziness — it gives the tiles room to move and provides a proper channel for the silicone.

Grouting, Sealing and the Finishing Touches

Wait at least 24 hours for the adhesive to set. Then mix your grout and work it diagonally across the joints with a rubber float, pressing it in firmly. Wipe the surface with a damp sponge before the grout sets hard, rinsing often, and keep the joints themselves intact rather than washing them out.

Once the grout has dried to a haze, buff the tiles with a dry cloth. Leave it another day before running a bead of silicone along the worktop and down the internal corners — smoothing it with a fingertip dipped in soapy water gives a clean, professional line.

Give everything a final clean and a polish, and stand back. A tidy splashback, done carefully, will look good for years and quietly transform the room.
