Application steps

Discover the application steps, the products used for this solution and other alternative products.

1

Not cracked and well anchored existing tiles

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

Smoothing compound for repairing detached tiles

PLANITOP FAST 330

After checking and preparing the existing substrate, fill any gaps left after removing damaged tiles by applying the skimming product with a trowel.

3

Adhesive

KERAFLEX MAXI S1 ZERO

Apply the adhesive on the substrate with a notched trowel suitable for the type and format of the tiles to ensure the back of the tiles is sufficiently wetted. Use the double-buttering method where specified by UNI 11493-1. 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

KERAPOXY EASY DESIGN

Once the adhesive has set, carefully fill the grouts to their full depth using a rubber trowel without leaving gaps or steps. After filling the grouts with epoxy mortar clean the surface while the mortar is still wet fresh with a cellulose sponge dipped in water and a Scotch-Brite® pad where required. Carry out any final cleaning required using UltraCare Kerapoxy Cleaner.

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.
