• Internal wet areas, bathrooms, laundries and other tiled areas;
• Balconies, decks, podiums and terraces;
• Roofs, as an exposed membrane finish (light pedestrian traffic). Parapets and external areas exposed to constant weather;
• Roofs to be covered by screeds or toppings including tiles.

Advantages

• Highly flexible and elastic;
• Excellent adhesion;
• Solvent free, non-hazardous;
• Excellent UV / weather resistant properties;
• Non re-emulsifying;
• Resistant to algal growth.

Technical Characteristics

Aquaflex WPU is a versatile ready-to-use, solvent-free, single component, water-based hybrid polyurethane membrane. Aquaflex WPU has a thixotropic consistency that makes it easy to apply on horizontal and vertical surfaces for both interior and exterior applications.

Aquaflex WPU cures to form a highly flexible Class III membrane with excellent adhesion properties. Aquaflex WPU complies with AS4858:2004 and AS4654.1:2012. Aquaflex WPU cures to a tack-free finish and permits light pedestrian service traffic. Aquaflex WPU provides excellent direct adhesion with Mapei's range of tile adhesives.

The over 400% elongation of Aquaflex WPU enables it to withstand normal expansion and contraction movements of the substrate due to temperature variations and vibrations. Aquaflex WPU is resistant to limewater (pH> 12), water which contains mild chlorides and normal household detergents and cleaning products.

Recommendations

• DO NOT apply Aquaflex WPU if the temperature is lower than +5°C or above +35°C.
• Aquaflex WPU should always be applied with a stable or falling ambient temperature.
• Always create sloping surfaces to drains where necessary to avoid the formation of water ponding.
• DO NOT apply Aquaflex WPU on damp cementitious substrates without first priming with Planiseal MR.
• DO NOT apply Aquaflex WPU on bitumen or asphalt membranes without firstly applying Primer for Aquaflex.
• DO NOT use Aquaflex WPU to cover cracks.
• DO NOT apply Aquaflex WPU on crumbly cementitious substrates, old floors which are not well bonded to the substrate or surface treatments which impede a good bond.
• Aquaflex WPU is suitable for light service foot traffic however it must be protected from abrasion caused by heavier traffic by installing ceramic tiles or other forms of protection.
