Mapei Aquaflex Roof is a ready-to-use flexible liquid roof membrane with fibres for continuous waterproofing layers on exposed surfaces such as flat roofs, paving slabs, cupolas and curved roofs.
Aquaflex Roof is a ready-to-use coloured waterproofing product for external applications made from synthetic resins dispersed in water, and when dry forms a continuous, flexible, waterproof membrane. Aquaflex Roof is resistant to all atmospheric conditions and UV rays, and guarantees long-lasting protection for the substrate. Aquaflex Roof is easy to apply using a long-haired roller, brush or spray on horizontal, sloping and vertical surfaces. Once dry, Aquaflex Roof forms a strong,
flexible, tack-free coating, suitable for occasional light foot traffic.
Mapei Aquaflex Roof is ideal for waterproofing and protecting flat roofs, paving slabs, cupolas and curved roofs. Once the substrate has been prepared Aquaflex Roof may be used on ceramic and stone coatings, cementitious screeds and screeds made using special binders (Topcem and Topcem Pronto), concrete, existing bitumen sheaths, wooden trimmings, galvanized sheet, copper, aluminium and iron.
Due to its flexibility, Aquaflex Roof is compatible with normal dynamic expansion and contraction stresses caused by temperature variations and vibrations.
All substrates, whether they are new or old, must be solid, clean, dry and free of all traces of oil, grease, old paint, rust, mould and any other material which could compromise the bond. Concrete and in general mineral substrates must be solid and dry with no rising damp. Any loose parts must be removed. Any hollows in the surface must be repaired with Mapeslope.
Prime the surface with a coat of Aquaflex Roof diluted with 10% of water. All wax, water-repellent treatments, etc. must be removed from the surface of ceramic substrates with a suitable detergent and / or by sanding. On old ceramic floors with gaps in the joints between the tiles, grout the joints with Adesilex P4 before applying Aquaflex Roof. Apply Eco Prim Grip on non absorbent ceramic substrates, while on any other type of substrate apply Aquaflex Roof used as primer diluted with 10% of water.
If applied on existing bituminous membranes, carefully hydro-blast the surface, wait until the water has drained off and treat the surface with Primer for Aquaflex. When applying the product on metal substrates, thoroughly clean the surface and apply a coat of Eco Prim Grip primer. Before applying Aquaflex Roof, pay particular attention to the expansion joints and the fillets between horizontal and vertical surfaces, which must be waterproofed using Mapeband Easy, rubber tape sandwiched between two layers of non-woven fabric, or Mapeband SA, self-adhesive butyltape, Mapetex 50 (h 20), bonded to the substrate with Aquaflex Roof.
Structural joints must be waterproofed with Mapeband TPE bonded in place with Adesilex PG4. Use a suitable kit from the Drain range to seal any drains.
The product is supplied ready to use. It is however recommended to mix the contents to perfectly blend the product. Apply two dry coats of Aquaflex Roof approximately 0.4-0.5 mm thick each. Wait until the first coat is completely dry and that it becomes slightly darker in colour before applying the next coat. The second coat must be applied in a criss-cross direction to the previous coat. The dry thickness of Aquaflex Roof must never be less than 0.8-1 mm.
If the substrate has micro cracks, insert Mapetex 50, non-woven polypropylene fabric between the two layers of Aquaflex Roof. Spread on a generous coat of Aquaflex Roof. While gradually applying the product, immediately lay the Mapetex 50 and go over the surface with a flat spreader or spiked roller to ensure it is perfectly wetted. Spread on a second coat of Aquaflex Roof once the first coat is completely dry to cover completely Mapetex 50. Protect the Aquaflex Roof membrane from rain until it is completely dry.
