7 SETTING OUT For Wall Tiling
Take a long length of timber (batten), mark the tile widths to help you identify where the tile will start and finish, remembering to leave space for the joints. The width of which are determined by the size of the tiles (BS 5385 – Part 1).
Set out horizontal position of the tiles so that the same size cuts are made either side of windows, etc. Avoid small difficult cuts as they can spoil the appearance. Plan each wall carefully, remembering that any patterns/designs will need to be matched in the corners of the room. For plain tiles each wall should be centralised avoiding any small cuts.
1. Find the lowest point of the base you are working to (skirting, bath top, work surface, etc.).
2. Place a tile against the lowest point and draw a line on the wall along the top of the tile. The start point of the line will depend on the setting out of the tiles, as the tile against the floor may be a cut tile.
3. Nail the batten along the wall to this line. Use the spirit level to ensure it is level. The first line of tiles will rest on this batten.
4. Draw a vertical (plumb) line at the centre of the wall. Use this to check that the tiles are in line vertically.
5. Spread the wall tile adhesive using a suitable tile adhesive trowel onto the wall. Work in small areas a metre at a time, so that tiles are fixed before the surface of the adhesive forms a skin. Press and twist the wall tiles into the adhesive starting at the

bottom and working upwards, one row of whole tiles at a time, using spacers (if required) to ensure a uniform joint. Check the horizontal and vertical lines with a spirit level every few rows.
Remove surplus adhesive and spacers from the joints prior to grouting.
If the tile does not have a glazed edge, a neat finish on external edges and corners can be achieved with the use of tile trim incorporated at the time of tiling.
To prevent the seepage of water around baths, basins and plumbing equipment such as shower taps, a plastic sealing strip or silicone sealant should be used.
For Floor Tiling
Check the overall flatness of the floor. If required, use a levelling compound.
Mark a chalk line on the floor down the centre
of the room parallel to the most suitable wall (normally this is achieved by viewing the room from the doorway).
Lay the tiles down this line and then work towards the wall you think is best, leaving a joint between the tiles of at least 3mm. Tile spacers can be used to achieve a uniform size joint, however they should be removed before grouting. Avoid small cuts, as they can be difficult to cut and do not look professional.
