Apply the tile adhesive to the substrate using a notched trowel. Choose a trowel that gives the correct coverage to the
tile. To achieve good adhesion, spread an initial thin layer of adhesive on the substrate using the flat side of the trowel.
Comb the adhesive with a suitable notched trowel horizontally to achieve a 2 – 6 mm bed thickness. Spread the mortar
adhesive to a manageable area that can be tiled within 5-10 minutes. Press the tiles firmly over the mortar adhesive and
immediately knock them into the desired position. Adjust the position of the tiles, if required, within its adjustability time
after installation.
Use the back buttering method for large format tile applications. Apply and comb the adhesive on the surface to be tiled.
Also, add the adhesive to the backside of the tile with/without combing.
