Preparation & Application

Preparation

Ensure that all surfaces are clean, dry sound, free from grease, dust or any other contaminating barrier, and capable of supporting the weight of tiling.

Make good any unsound areas before tiling. Remove flaking or peeling layers and any existing tiles or paint.

Prime dusty or porous surfaces with weber PR370 or weber AD250 and allow to dry before tiling.

Application

Do not use at temperatures below 5°C.
Spread the adhesive onto the wall, rather than onto the tiles, using a suitable notched trowel. Do not spread an area larger than can be tiled in approximately 20 minutes. Studded-backed tiles may also need to be buttered with adhesive.

Fix the tiles within 20 minutes of applying adhesive (less at elevated temperatures). If lightly pressed, the adhesive should still stick to the fingers. If not, then it should be removed and more applied. Firmly press the tiles into the adhesive bed, with a twisting or sliding action, leaving at least 2 mm gaps for grout joints.

For dry areas, the contact area between the adhesive and tile must be at least 70%, uniformly over the whole tile. In intermittently wet areas, it is essential that there are no voids under the tiles. The final bed thickness should be no more than 3 mm.

It is good practice to occasionally remove a tile to check that the required contact is being achieved.

Remove any excess adhesive from the tiles and joints before it sets and any tile spacers after approximately 1 hour.

Ready-mixed adhesives gain strength on drying, so leave for a minimum of 24 hours before grouting. On non-porous surfaces, leave for at least 3 days. These times should be extended in poor drying conditions such as when using larger tiles or tiling at low temperatures.

For wet areas, particularly power-showers, an appropriate grout should be used to minimise water penetration. Leave for 2 weeks after grouting before using the shower.

Plaster
Tile onto a plaster finish coat. Leave new plaster for at least 4 weeks so that it will be strong enough to support the tiling weight. Priming with weber PR360 is recommended. Plaster can support 20 kg of tiling per m2.

Plasterboard
Securely fix and brace all boards to ensure stability. They should be screwed, not nailed, at 300 mm centres horizontally and vertically. Plasterboard can only support 32 kg of tiling per m2.

Cement/sand render
Leave new surfaces to dry for at least 2 weeks before tiling.

Brickwork/blockwork
Leave new surfaces to dry for 6 weeks before tiling. Ensure that the surface is sufficiently flat. Lightweight blocks must be primed and are not suitable for large tiles.

Allowance for movement
Flexible joints should be incorporated to allow for slight movements due to changes in temperature, humidity etc. as indicated by BS5385:

a) where the tiling meets other materials (e.g. floor perimeters)
b) along all internal corners - vertically and horizontally
c) over existing movement joints or changes in background material
d) dividing large tiled areas into bays (every 3 - 4.5 m)
