Prepare surface

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 PR360 or weber AD250 and allow to dry before tiling.

Apply

Do not use at temperatures below 5°C.

Spread the adhesive onto the wall using a notched trowel. Spread enough adhesive to cover an area which you can tile 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 higher room temperatures). If lightly pressed, the adhesive should stick to your 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.

Remove any excess adhesive from tiles and joints within one hour before it sets, and make sure any tile spacers are removed after about an 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.

Allow joints for movement

Flexible joints should be incorporated to allow for slight movements due to changes in temperature, humidity etc. as indicated by BS 5385:

• Where the tiling meets other materials (e.g. floor perimeters)
• Along all internal corners - vertically and horizontally
• Over existing movement joints or changes in background material
• Dividing large tiled areas into bays (every 3 - 4.5 m)
