Adhesive
Apply the adhesive using the double-buttering method with a notched trowel suitable for the type and format of the tiles so that the back of the tiles are sufficiently wetted with adhesive. While installing the tiles use levelling systems from the MapeLevel line to maintain the correct width for the grouts and to reduce lippage between adjacent tiles.

Grout
Once the adhesive has set, carefully fill the grouts to their full depth using a rubber trowel without leaving gaps or steps. When the mix starts to lose its plasticity, clean off any excess product with a damp cellulose sponge. They may also be finished off while the product is partially hardened by going over the surface with a damp abrasive pad (such as a Scotch-Brite® pad). Remove any cementitious residues with UltraCare Keranet.
13
Sealant
Seal the perimeter and expansion joints after inserting Mapefoam to set the correct depth and then finish off the surface of the sealant with UltraCare Smooth Silicone.
