SikaCeram®-277 Flexible Standard Set should be added to clean water. Mix approximately 1 part water to 3 parts powder by volume (20 kg powder to approximately 5 L of clean water) and mix to a slump free mortar. Never add further water once the adhesive has started to go off. This will destroy the bond strength. Always add powder to water

All surfaces should be clean, dry and free of dust and loose material before commencing. Refer to above for specific surface preparation.

Use a notched trowel to give a ribbed mortar bed on the substrate, to which the tiles should be firmly bedded with a twist and slide action to ensure full contact.

• Use a 3 mm x 3 mm notch at 6 mm centres for mosaics and thin flat backed wall tiling.
• Use a 5 mm x 5 mm notch at 10 mm centres for general wall tiling.
• Use 10 mm x 10 mm notch at 16 mm centres for general floor tiling.

SikaCeram®-277 Flexible Standard Set will remain workable for up to 4 hours depending on absorbency of substrate and temperature. Lightly touch the adhesive periodically and, if a skin has formed, remove the adhesive and apply a new layer. It is good practice to periodically remove a tile and check that the adhesive covers a minimum of 75 % of the tile.

All surplus adhesive must be removed whilst the adhesive is still wet using a dampened cloth or sponge, particularly along the grout lines.

Grouting may proceed as soon as the tile bed is sufficiently firm, which will be around 24 hours at room temperature. This period will, however, be extended in cold conditions.

When the adhesive is fully set, wall and floor joints can be grouted using SikaCeram^® CleanGrout.

Subfloor Heating

Fixing over a heated sub-floor requires adhesive to cure for at least 2 to 3 weeks before switching on the heating and gradually raising the set temperature by 2 °C per day until the floor is at its required operating temperature.

Clean tools in water after use. Wash hands immediately after using this product.
