Aquastop Nanoflex®


Suitable for use on terraces, balconies, horizontal surfaces and swimming pools.


A single component, certified, eco-friendly, breathable, anti-alkali and chlorine-resistant, mineral membrane for the flexible waterproofing with high levels of adhesion and durability of substrates before laying with adhesives, suitable for use with EMICODE® Green Building. It has low CO2 emissions, very low volatile organic compound emissions and is recyclable as an inert material.

Aquastop Nanoflex® develops a smooth, fluid mixture that can be adjusted by varying the amount of water to obtain optimal workability for the site conditions, guaranteeing maximum adhesion of the bonded system.

Features and benefits:

  • Suitable for internal and external use on floors and walls.
  • Breathable.
  • Crack bridging ability.
  • Specifically intended for laying ceramic tiles, natural stone and glass mosaic using adhesives from the H40® range.
  • Suitable for overlaying.
  • 30% better coverage than two-component systems.
  • Includes Nanotech technology which makes it completely water repellent and gives high chemical stability.
  • EMICODE® Green Building rating: Eco 3.
  • CE marked to BS EN 14891, contributes to LEED points.


Suitable for use on terraces, balconies, horizontal surfaces and swimming pools.

– Suitable substrates:

Mineral screeds, monolithic cement-based screeds, existing floors covered with ceramic and marble tiles, dimensionally stable natural stone well-anchored to the substrate and clean, cement-based plasters/ renders and cementitious mortars, aged concrete.

Consult manufacturer for recommended substrate preparation and substrates not suitable for the application of this product.
