PREPARATION

Ensure that all surfaces are clean, dry, sound and free from dust, grease or any contaminating barrier.

Make good any unsound areas and remove flaky or peeling layers before tiling.  Porous or dusty surfaces should be primed using a suitable primer and allowed to dry.

Check before use that the colour of the adhesive does not cause staining or discolouration of light coloured or translucent tiles.

MIXING

Gradually add approximately 4 parts of powder to 1 part of clean water (measured by volume), and mix to a smooth, workable, stiff paste (non-slip wall tiling requires 3.4 litres of water per 20 kg of adhesive and for floor tiling, 4 to 5 litres).

Use within 30 minutes of mixing.

Do not attempt to extend the pot life by adding more water to the mix.

APPLICATION

Do not use at temperatures below 5°C.
Apply the adhesive onto the substrate covering up to 1 m² at a time (or no more than can be tiled within 10 minutes). Use a suitable notched trowel to achieve a bed thickness of 3 to 6 mm. Tiles with studded backs may need to have adhesive buttered onto the tile back as well.

Bed the tiles firmly into the adhesive with a slight sliding and/or twisting action, to ensure a good contact. It is good practice to lift an occasional tile after fixing, to verify that the required contact is being achieved. In wet areas, external areas and all floors, the final adhesive bed should be free from voids. Leave appropriate clearance joints for grouting and make any adjustments within 10 minutes.

Carefully clean off any excess adhesive with a damp cloth or sponge from the tiles and joints before it sets.

Leave for at least 2 hours before grouting. Longer is required at lower temperatures or when tiling onto impervious or sealed surfaces. For swimming pools, leave at least 3 days before grouting, and then leave for a further 3 weeks before filling.

 

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 on walls, 8 – 10 m on floors)
