How to measure for tiles and calculating quantities

The wall surface should be measured, and a simple calculation will provide the overall square area. Remember to subtract door and windows openings or any other surface not being tiled. Tiles are sold by the square metre (or square yard) quantities and it’s important to make sure they are from the same batch. This avoids any discrepancies in coloration. Always remember to allow for between 10% & 15% extra in case of damage and wastage during tiling and for future replacement tiles.

To tile a wall the following materials and tools will be required:

Preparing the wall for tiling

In damp or humid situations, the backing for the tiled surface must be waterproof, this is achieved by using tile backer board or by tanking the plasterboard. New plaster must be allowed to dry out completely which usually takes 4 weeks. Minimum thickness of approx 12.5 mm is required for plasterboard and the weight of tiles should not exceed 32 kg/sq.m. For tiling over painted surfaces, the important consideration is that the surface is level, smooth, clean and free from dirt and grease. The painted surface will need sanding and then Primed.

Fixing wall tiles

Preparation is the key to successful wall tiling (and all other things DIY related), this means making sure the design of the wall tiles layout avoids awkward cutting of tiles. A 100 x 50 mm batten can be used to help establish the optimum tile layout. Measure one complete tile up from the lowest point on the wall to be tiled. Fix the batten to the wall making sure it is level, the first line of tiles sits on this datum. Then draw a vertical line on the wall to make sure tiles are being laid in line vertically.

Applying the tile adhesive

Working in small areas spread the adhesive on the wall using the notched trowel. Making sure the tiles are being located in the correct direction place against the wall from the bottom to the top. Establish one row at a time ensuring that the adhesive is still wet and that vertical and horizontal lines are true. Use spacers to help with an even layout. Follow recommended instructions in the case of tiles to be cut. For corners and other awkward locations use adhesive on the tiles rather than the wall.

How to grout tiles

Do not start grouting till 24 hours have elapse after tiling. Grouting is as important as the choice of tile so make sure you choose the correct one. After removing the tile spacers. Push the grout between the tiles into the joint using a rubber trowel. Remove any excess by using the grout float and then wipe off with clean water and sponge.

British Standards

The relevant British Standards for tiling are the following:

BS 5385-3:2007 – Wall and floor tiling – Part 3: Design and installation of internal and external ceramic and mosaic floor tiling in normal conditions – Code of practice
