Application

Intended use:

  • For internal and external use to waterproof, separate and compensate for vapour pressure prior to laying of ceramic tile, natural stone and hardwood floor coverings for domestic, commercial, industrial applications (such as industrial kitchens, food industries, warehouses) and for street furniture (check that the size and thickness of the materials to be laid is suitable).
  • Balconies, terraces, flat roofs and surfaces of any size.

Suitable substrates:

  • Screeds, including any that are cracked and not completely cured or with possible vapour pressure caused by residual humidity, heat-radiant slabs.
  • Existing ceramic, marble floor tiles, natural stone floorings anchored to the substrate.
  • Cured concrete.
  • Fibre-cement and plaster-board panels anchored to the substrate.

Do not use on anhydrite-based substrates without the use of Active prime fix professional, concentrated, water-based surface insulation, on bituminous sheeting, on exposed surfaces, on inverted roofs made with insulation panels or low-density screeds.

Description

Anti‑cracking waterproof membrane with high adhesion for balconies, terraces and horizontal surfaces before the laying of ceramic tiles, natural stone and hardwood floors; it creates a waterproof surface even when overlaid on cracked supports, supports that have not been perfectly cured or supports that might contain vapour pressure due to residual substrate moisture content.

Aquastop Green revolutionizes laying with the laminate no crack, re‑writing performance standards to allow applications that are impossible for mineral products.

Features and benefits:

  • Specific for anti‑cracking laying with H40 adhesive range in the revolutionary laminate no crack.
  • It waterproofs any surface, old or new, damp or dry, cracked or subject to dimensional variations.
  • It compensates for hygrometric shrinkage and thermal deformation stress.
  • It reduces on‑site working times: waterproofing and laying of the coating without waiting, withstands foot traffic immediately.
  • Solves the problem of respecting substrate joints in staggered or diagonal laying (cuts in doorways).

Specification data - Polymeric membranes

Material

Multi-layer composite polymer system.

Guidance for specification option:

The membrane is a high-technology, multi-layer composite polymer system comprising:

  • PA - hydrophobic PA fibres with high tensile strength to guarantee a superior and more evenly distributed available contact surface.
  • HDPE - waterproof and variable geometry HDPE structure to guarantee physical separation between the substrate and the flooring.
  • TNT - highly breathable sheet to guarantee passage of the vapour from uncured screeds.

Third-party certification

EC 1 plus GEV-Emicode.
