LA CHAPE XXS® DUAL TECH

PRE-MIXED, LIGHTWEIGHT AND FIBRE-REINFORCED, ULTRA LOW-PROFILE SCREED. 1200 kg/m3

LA CHAPE XXS® DUAL TECH is the pre-mixed, lightweight, fibre-reinforced cement screed for projects where only a thin build-up is possible: it is applied from 1 to 15 cm, including as a bonded screed, and weighs half as much as a traditional screed. It is designed for renovations and new buildings, in apartment blocks and detached houses, on any substrate.

With one product you choose the consistency on site: traditional (3.0-3.5 L of water per bag) or fluid (4.5-5.0 L). Made with cement, special aggregates, fibres and EPS beads coated with E.I.A. additive, it offers high strength (CT-C12-F3 in the traditional version) and contributes to thermal and acoustic insulation. It does not settle, does not shrink and does not crack.

It is walkable after 12 hours; ceramic tiles can be laid after about 24 hours and floating parquet after about 3 days. It is mixed in a cement mixer or with a drill and pumped with a plastering machine or subfloor machines.
