Application steps

1
Cementitious screed
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
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
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
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
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
Seal the perimeter and expansion joints after inserting MAPEFOAM to set the correct depth, then finish off the sealant surface with ULTRACARE SMOOTH SILICONE.
