Tile a Splashback With Marrakech Design Cement Tiles in 8 Steps

Cement tiles are heavy for their size. A 20x20 cm Marrakech tile typically sits around 600 to 700 grams, which puts a square metre at about 18 to 20 kg on the wall. That load affects the adhesive from the first decision: use a white C2 cement-based adhesive. Standard light wall-tile glue can creep before it cures, and grey adhesive can shadow through the porous pigment layer, making lighter colours in the pattern look duller.

The other fixed point is the first seal. Cement encaustic tiles are unglazed, so grout pigment and cooking oil can bond into the body of the tile. Seal the faces before grout ever reaches them, especially on a kitchen splashback where grease, steam, and wiping are part of daily use.

Steps 1 and 2: Let the tiles settle, then lay out the full run

Open the boxes and leave the tiles stacked face-up in the room for 48 hours. Cement tiles can hold residual moisture from manufacture. If the core is still damp when the tile is fixed, efflorescence can appear later as a white salt bloom while the tile dries against the wall.

Use that waiting time to dry-lay the splashback on the floor. Marrakech patterns rarely arrive with machine-perfect uniformity. In a batch of 50 tiles, expect small shifts in colour: a warmer ochre in one tile, a cooler tone in another, plus the occasional corner chip.

Lay out the whole visible run before adhesive is mixed. Move any obvious colour outliers toward ends that will be softened by a worktop return, wall cabinet, or side wall. Keep chipped faces out of the centre of the splashback, where under-cabinet light and eye level make defects stand out.

This is also the moment to settle the pattern logic. A four-tile repeat that forms a larger medallion needs a fixed datum, often the hob centreline or the centre of the visible wall. If the first tile is chosen only because it fits the left edge neatly, the medallion can drift and arrive half-cut behind the hob.

Step 3: Seal every face before fixing

Set the clean, dry tiles on the floor and apply a penetrating sealer to the face and edges of each one. A water-based stone and cement sealer such as Lithofin MN or Fila MP90 soaks into the pigment surface and creates the barrier that keeps grout pigment and oil from grabbing into the tile body.

Use two thin coats, about 20 minutes apart. Wipe the surface back after each coat so the sealer does not pool or dry with a glossy film. Let the sealer cure for the time shown on the tin, usually 4 to 6 hours.

Test one sealed tile with a few drops of water. Beading water means the surface is protected. Water that darkens the tile within seconds means that tile needs another thin coat before fixing.

Glazed ceramic can go through installation with a very different sequence. Cement tile needs this early seal because the surface itself is porous pigment.

Step 4: Set a level datum line

Use a spirit level to find the highest point of the worktop. From there, measure up one full tile plus a 2 mm spacer and snap a chalk line. Fix a temporary timber batten along that line so the first course has a true level support.

Worktops are rarely perfectly level across a full run. A 3 mm fall over 2 metres can make the top course look wrong against the underside of wall cabinets. Tiling up from the batten keeps the visible courses straight, while the small tapered space left above the worktop is dealt with at the end using flexible silicone.

That lower joint needs movement capacity because the worktop and wall move independently. Rigid grout at that junction can crack within a season.

Step 5: Mix, comb, skim, and press

Mix the white C2 adhesive to a stiff peanut-butter consistency, allow it to slake for 5 minutes, then remix. Spread only about half a square metre at a time with a 6 mm notched trowel held at 45 degrees.

Cement tiles show poor bedding more readily than many glazed tiles. An air pocket behind a porous tile can become a damp spot, and that dampness can telegraph through the face as a dark patch. For a splashback, aim for near-full coverage.

Back-butter each tile with a thin skim of adhesive before placing it on the wall. Press the tile home with a slight twist so the ridges collapse behind it. Sliding the tile around after placement can smear adhesive into the joint line and disturb the pattern.

Use a rubber grout float laid flat across four tiles at a time, then tap lightly to check that they sit in the same plane. Cement tiles vary a fraction in thickness. A proud edge can cast a sharp shadow when wall lighting runs across the splashback.

Set the joints at 2 mm with cross spacers. Tighter joints make the handmade, unglazed edges work against each other and can pull the pattern off line.

Step 6: Make the cuts around sockets and the hob

An angle grinder with a diamond blade is the practical cutting tool for these tiles. A manual snap cutter scores glazed tile cleanly, yet it tends to crumble the softer cement body and leave a ragged edge.

Mark cuts on the sealed face, clamp the tile over a board, and cut from the face side so small chips are pushed toward the underside. For a round opening behind a tap or a socket back-box, use a diamond hole saw run slowly with water on the blade. The water keeps the cement from overheating and cracking.

Cut socket openings a few millimetres oversize. The faceplate covers the gap, and a tight opening in a brittle tile can split when the wall flexes.

Step 7: Grout with a colour that lets the pattern read

Leave the adhesive for 24 hours before grouting. Use an unsanded grout because sanded grout can scratch the soft sealed pigment surface as it is worked across the joints.

Grey grout can read as a hard grid over a busy Marrakech pattern, visually breaking the field into separate squares. A grout close to the tile background, such as soft sand or off-white, lets the repeat read more continuously. Mapei Ultracolor Plus and Mapei Keracolor both include colours that sit near the typical bone and ochre grounds of Moroccan tiles.

Work the grout diagonally across the joints with the float and remove excess promptly. On sealed cement tile, haze can start to grip in a short window. Wipe with a barely damp sponge in clean water, changing the water often. Flooding the surface can wash pigment out of the fresh grout joints and leave them patchy.

Step 8: Seal the finished surface and form the movement joints

After the grout has cured for 48 hours, apply one more coat of the same penetrating sealer across the whole splashback, covering tile faces and joints together. This final coat helps protect the grout lines, the most absorbent part of the finished surface and the first place cooking oil tends to stain.

Run colour-matched neutral-cure silicone along the bottom joint where tile meets worktop, and along internal corners against adjacent walls. Tool it with a wet finger in a single pass.

A worked thickness example

Plan the finished depth before ordering surrounding parts. A Marrakech tile is commonly 16 mm thick. Add a 4 to 6 mm adhesive bed, and the finished splashback stands 20 to 22 mm proud of the wall.

That projection has to clear the depth of socket back-boxes and any under-cabinet trim. If a floating shelf will sit above the splashback on the same wall, the bracket fixings now have to pass through the tile and adhesive before they reach the substrate. Plasterboard mounting toggle bolts for that shelf must be long enough to pass the full build-up and still seat properly in the wall cavity.

Measure the tile, adhesive, trim, socket, and shelf bracket stack before the brackets arrive. The remaining mismatch is physical: a porous handmade surface wants protection, while the pattern only looks effortless when those protective layers stay invisible.
