1
Preparing the surface

  • 1.1 Remove any accessories from the wall.
  • 1.2 Clean the surface and repair any holes.

2
Drawing reference lines

  • 2.1 Trace a horizontal line along the wall where there will be a full row of tile.
  • 2.2 Trace a vertical line the size of a mosaic.
  • 2.3 Install a tile finishing trim with flat head nails for a clean finish.

3
Spreading the adhesive

  • 3.1 Mix the adhesive according to the manufacturer’s instructions.
  • 3.2 Starting in the bottom corner, spread the adhesive on a 3' surface.
  • 3.3 Work with the smooth side of the trowel at a 45° angle, making sure you can still see the reference lines.

4
Installing the first sheet

  • 4.1 Lay the first sheet of tiles following the reference lines.
  • 4.2 Place spacers at the bottom of the wall so that the mosaic isn’t directly on the moulding.

5
Adhering the sheet

  • 5.1 To make sure the sheet is well adhered, move the sheet lightly.
  • 5.2 Tap the tile with a mallet to adhere the sheets to the wall.

6
Continuing the installation

  • 6.1 Install the second sheet and insert tile spacers in between, creating uniform joints.
  • 6.2 Make sure it’s level, flat, and uniform.
  • 6.3 Cover the entire surface.

7
Preparing the tiles for the extremities

  • 7.1 Measure and cut the necessary sheets to cover the extremities.

8
Cleaning adhesive residues

  • 8.1 Clean the adhesive residues with a humid sponge.
  • 8.2 Wait 1 to 2 days before applying the grout.

9
Applying the grout

  • 9.1 Mix the grout according to the manufacturer’s instructions.
  • 9.2 Remove the spacers and dampen the surface with clean water.
  • 9.3 Hold the rubber trowel at a 45° angle and apply the grout evenly in the cracks.

  • 9.5 Remove excess as you go.
  • 9.6 Clean the surface with a wet sponge, moving diagonally.

Top tip

Do not apply grout in cracks that separate the tile from another material (the finishing trim, for example.) Do not use too much water while cleaning the grout, it’ll be diluted otherwise.

Finishing the installation

  • 10.1 Apply grout sealer to the joints.
  • 10.2 Wait around 10 days, then caulk the expansion joints with silicone sealer.
