Coverage		Approx. 2.0 - 3.0 Kg/m2 using 3 x 3mm notched trowel Approx. 5.0 - 5.5 Kg/m2 using 6 x 6mm notched trowel Approx. 10.0 - 11.0 Kg/m2 using 12 x 12mm notched trowel
Application Instruction		1) Spread the adhesive onto the substrate using either a 6mm x 6mm notched trowel (for wall tiling) or a 12mm x 12mm (for floor tiling). The choice of trowel shoild be governed by the size of tiles, depth of knobs, grooves or ridges on back of tiles and substrate surface. 2) Use the flat side of the notched trowel to spread the mix onto the receiving surface. Use the notched side of the trowel to apply the required amount of the mix in one direction. 3) Press the tile in perpendicular motion and tapped into position to ensure positive contact with the adhesive and adjust within 5-10 minutes. 4) For optimum bonding and better adhesive-tile coverage, apply a layer of adhesive at the back of the tile and follow the above-mentioned instructions. 5) The adhesive must be wet when the tiles are laid. Do not allow the adhesive to skin over prior to titling. Should a skin have formed, break the skin by re- trowelling the adhesive in opposite direction. 6) Make sure there are no voids under the tiles. NOTE: - Due to atmospheric condition, the “skin-over” of the adhesive may occur after 5-10 minutes. Do apply the adhesive in a small area with tiles within this period of time. - “Skin-over” can be checked by placing the tip of index finger lightly to the adhesive bed surface
Cleaning		Clean the tools immediately after use with water. Mineral spirits may be used to remove primer that has dried on tools.
