What is this system for?

Waterproof without removing the existing floor.
Roofs
Long-lasting protection against leaks.
Swimming pools
Pool shells and copings, with a warranty.
Renovations

Installation
Install it yourself in 3 steps
-
Prepare the substrate
Clean it and check that it is sound. There is no need to remove the old floor covering: the membrane is laid on top. Maximum residual moisture of 3%.
-
Bond the membrane
Bond it with tile adhesive, overlapping 10 cm, and seal the overlaps with SEALPLUS. Resolve corners, scuppers and pipe penetrations with the preformed pieces.
-
Tile on top
Lay the new stoneware or porcelain tile directly over the membrane with C2 tile adhesive.
No certificate or special machinery

Producto serio, de los que ya no se encuentran. Después del invierno más lluvioso, ni una gota abajo. Le doy 4 estrellas porque el envío tardó un día más de lo previsto.

Assenta muito bem com cimento-cola, as juntas ficam perfeitas com a banda. A calculadora do site acerta em cheio nos rolos.
