• Apply the adhesive with a notched trowel in a single direction. Apply the tile, while pressing into the wet adhesive, break the adhesive ridges with the tile to fully bed the tile into the adhesive.
• It is advisable to periodically check the backs of the tiles for adhesive coverage requirements as the AS3958.1-2007.
• Only apply as must adhesive that can be covered prior to adhesive skinning. If skinning occurs remove and replace with fresh adhesive.
• Remove any excess adhesive from the face of the tile with a damp sponge and ensure grout joint are of uniform depth.
• Movement, expansion and control joints must be installed as per AS 3958.1-2007.
