4. If the final line of tiles before the wall is less than half a tile wide, adjust all the tiles across until the gap is at least half a tile wide. This avoids small cuts which are extremely difficult to make.
Check the information on the adhesive pack. Apply adhesive to an area of about one square metre at a time or it will start to harden before the tiles are applied to it. Use tile spacers between every tile and ensure these

tiles directly onto a concrete floor.
Prepare the base floor MOST IMPORTANT: It is essential that the concrete surface is level and sound. If there are pronounced dips or hollows or expansion joints these should be filled and levelled. There are a number of fillers available for this job. Also, when tiling whole house floors, tiling should not be carried out for 3 months after pouring concrete. The concrete floor should be dry, that is, has lost its initial dampness. Check this by placing a rubber mat on the concrete overnight. If there is moisture on the surface when you move the mat next morning the concrete is too moist for tiling.
are pushed down fully to enable you to grout over them. Every so often use a straight edge or level to make sure all the tiles are laying flat. Any tiles above or below the level of adjoining ones should be removed and some adhesive adjusted. Do not leave this job for too long or it will be impossible to remove the tiles. Fix all whole tiles, then cut and fix the tiles round the edge. To mark the correct shape to fit shapes, cut a piece of cardboard as a template. Use this to mark the cutting line on the tile.
1. Laying out the tiles Mark and then cut this line
In a bathroom most of the cut edges can be hidden under the bath, vanity unit or around the toilet. If possible it is better to tile the floor with all the bathroom fixtures removed. Make sure that the tiles look straight. If the room is not ‘square’ or is an irregular shape this can be a problem. Line up the tiles on the floor so they look straight as you enter the room.
3. Work outwards towards the walls leaving a space between the tiles. Centre line Plastic tile spacers should be used to make this gap between the tiles. Any gap between 3mm and 12mm can be used. Often a wide gap of 6mm or more is more attractive than a narrow gap.
3. Straight cutting at edges Place a whole tile on top of the last complete tile that was adhered in place. Then hold another whole tile on top of this tile so that it touches the wall, mark a line along the underneath tile. The off-cut from the underneath tile will fit into the gap. 4. Laying tiles Apply adhesive to floor with 6mm notched spreader for tiles without lugs and 8mm spreader for tiles with lugs. Push each tile onto the adhesive until it oozes out at the corners. Remove any excess adhesive and leave to dry fully before grouting.

Grout when the adhesive is fully dry, and not before. Using waterproof grout, force the mixture between the gaps in the tiles with a grout spreader. Remove any surface grout regularly with a damp cloth.
