MAPEI AQUALFLEX WPU

x e l f U a P u W q A Ready-to-use quick drying and flexible Class III water-based hybrid polyurethane membrane for internal and external waterproofing applications WHERE TO USE Aquaflex WPU can be used on the following: • Concrete, screed, render and masonary surfaces, fibre cement sheeting, wet area rated plasterboard and timber sheeting.

• For further information on suitable surfaces and substrates please contact Mapei Technical Services on Freecall 1800 652666.

Some application examples • 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

coats (approx. 1 mm maximum per coat).

Wait until the first coat is dry before applying further coats crossways (1-2 hours according to temperature conditions).

The final thickness of Mapegum WPS must never be less than 1 mm, in order to form a consistent, flexible continuous coat. Make sure that there are no gaps caused by thixotropic liquid imperfections in the substrate.

Mapegum WPS is used as an anti-fracture light grey on cracked substrates, we membrane recommend inserting a layer of 4.5x4 mm Mapenet 150 in the first layer of fresh 1.3 Mapegum WPS to act as a reinforcement (refer to the Mapenet 150 Technical Data 8.5 Sheet).

To further improve both elongation at failure and crack-bridging of Mapegum WPS, we65% recommend inserting Mapetex Sel large-mesh non-woven polypropylene fabric (refer to the Mapetex Sel Technical 60 Sheet).
