Installation of ceramic tiles

Application steps

1
Existing ceramic floor
The old tiles must be clean and well bonded to the base layer. Clean the surface of the existing floor with UltraCare HD Cleaner diluted 1:5 or 1:10 with water according to the amount of dirt on the floor.
2
Filling mortar for removed tiles
After checking and preparing the existing substrate, fill any gaps left after removing damaged tiles by applying the skimming product with a trowel.
3
Sealant (spots application)
Bond the fibre cement or gypsum fibre panels to the existing substrate with the adhesive applied in beads around 20-30 cm apart.
4
Thin heating system
5
Primer
Apply the primer with a brush or roller over the entire surface of the panels.
6
Adhesive (1st coat)
Apply a first layer of adhesive using the smooth edge of a trowel to fill the cavities in the panel/pipework.
7
Adhesive (2nd coat)
Apply a second layer of adhesive using the double-buttering method with a notched trowel suitable for the type and format of the tiles to ensure the back of the tiles is wetted sufficiently. 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.

Sealant
MAPEFOAM + MAPESIL AC
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.
