System for installing ceramic tiles over existing flooring and installing a soundproofing layer directly under the floor

Application steps

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

1

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

Adhesive

ULTRABOND ECO S955 1K

Apply the adhesive with a No.1 or No.2 MAPEI trowel according to the roughness of the substrate to bond the soundproofing membrane.

3

Soundproofing membrane + perimetral band
MAPESONIC CR + MAPESONIC STRIP

Apply the adhesive tape along the perimeter walls, pillars and along any other element passing through the floor. Apply the soundproofing membrane by butting the sheets against one another.

4

Adhesive

KERAFLEX MAXI S1 ZERO

Apply the adhesive 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.

NOTES:

The choice of adhesive and covering varies according to type and format of tiles.
