Application steps

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

1

Cementitious screed

TOPCEM PRONTO

Position a series of levelling guides, spread the mix, carefully compact the mix and float-finish the surface.

2

Drain for floor-level shower
PP DRAIN AQUA

Position the drain and connect it to the drainage system through a plug-in pipe of suitable diametre. Apply MAPEGUARD WP ADHESIVE by roller or brush or using a 3 mm notched trowel to bond the waterproofing membrane to the drain.

3

Rubber tape

MAPEBAND PE 120

Apply the elastic tape for fillet joints and any accessory item for waterproofing through-pipes and drain elements on MAPELASTIC ACQUADEFENSE ZERO while still fresh.

4

Ready-to-use waterproofing membrane

MAPELASTIC AQUADEFENSE ZERO

Apply two layers of product with a brush, long-pile roller or trowel to form a total thickness of at least

0.8/1 mm.

5

Shower profiles
GLASS PROFILE

Apply the front and sloping shower profiles to finish the sloping surface and to insert glass walls using the same adhesive used for installing the covering.

6

Adhesive

KERAFLEX EXTRA 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. To maintain the correct grout size and avoid the formation of lippage between adjacent tiles during installation, use the levelling systems from the MAPELEVEL range.

Porcelain tiles

8

Grout

ULTRACOLOR PLUS

Once the adhesive has set, carefully fill the grouts to their full depth using a rubber trowel without leaving gaps or steps.
When the grout loses its plasticity, clean the excess product with a wet hard cellulose sponge.
It is possible to finish the surface also when the mix is partially set, with a damp Scotch-Brite^® sponge. Remove any cementitious residues with ULTRACARE KERANET.

9

Sealant

MAPEFOAM

MAPESIL AC ECO

Seal the perimeter and expansion joints after inserting MAPEFOAM to set the correct depth, then finish off the sealant surface with ULTRACARE SMOOTH SILICONE.
