weberset thick bed

Prepare surfaces

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 with weber PR360 and allowed to dry before tiling.

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

Mix

Gradually add approximately 4 parts of powder to 1 part of clean water (measured by volume), and mix to a smooth, workable stiff paste. Normal usage requires 4 litres of water per 20kg adhesive.

Use within 2-3 hours of mixing and do not attempt to extend the pot life by adding more water to the mix.

Apply

Apply the adhesive onto the substrate covering up to 1m² at a time (or no more than can be tiled within 20 minutes). Use a suitable notched trowel to achieve a bed thickness of at least 3mm. Large or uncalibrated tiles will need to have adhesive buttered onto the tile back as well.

Bed the tiles firmly into the adhesive 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. 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 and leave for at least 24 hours before grouting. Longer is required at lower temperatures or when tiling onto impervious or sealed surfaces.

Do not use at temperatures below 5°C.
