Before you get started you need to check the condition of the wall surface (substrate). Ensure that the wall to be tiled is clean, level, firm, completely dry, sound and free from dust, grease or any other contamination. Any weak/loose surface material or layers must be removed to ensure a good bond between the adhesive and tiles.
If you are tiling over existing tiles, then there are a few things you’ll need to keep in mind. Read our step by step guide on tiling over tiles
Once you are happy to proceed apply a diluted coat of weber PR360 primer to walls, ensuring that you have full coverage, with a roller or brush. The primer should be diluted with clean water which is designed for use on a wide range of substrates. weber PR360 regulates the porosity of the substrate and improves adhesion. Allow weber PR360 to become touch dry.
Measure your wall and mark the centre point. Then draw a vertical level line through this centre point using a spirit level. Measure your tile and mark out the centre point on the tile and line this up with your vertical line on the wall. Then mark out the edges of the tile onto the wall and copy this procedure across the wall.
