SikaCeram®-777 is spread onto the substrate using a proper and suitable notched trowel. The choice of trowel shall be governed by the size of the tiles, depth of knobs, grooves or ridges on the back of the tiles and the evenness of the substrate.
Use the flat side of the notched trowel to spread the adhesive onto the receiving surface at approximately 1 m². Then, use the notched side of the trowel to determine the required amount of adhesive in one direction.
Press the tile in a perpendicular motion and tapped into position to ensure full contact with the adhesive. Adjust within the open time limit, ~30 minutes.
For tile with grooves or ridges, it is necessary to skim a layer of adhesive/butter coat the back of the tiles. This is to ensure good bonding and complete coverage between the adhesive and tile so that proper adhesion and support takes place.
Ensure that the adhesive is wet when the tiles are laid. Do not allow the adhesive to skin-over prior to tilling. Should skinning occur, break the skin by re-trowelling the adhesive in the opposite direction.
Do not spread more than 1 m² of the adhesive at any one time. Fix the tiles within 15 minutes of applying the adhesive and check the contact by occasionally lifting the tiles.
Ensure there are no excessive voids under the tiles. At the perimeters, leave adequate wall and floor joints.
For external tiling, protect from direct sunlight and rain by means of a shelter. It is the user’s responsibility to determine the condition and suitability of all surfaces prior to application.
Grouting
Tile joint grouting should preferably be carried out at least 24 hours after completion of tiling or until the adhesive has set and dry sufficiently.
Setting may be delayed on dense or impervious surface.
