Features & Benefits

• Aquaflex Roof may be used on:
  • Ceramic and stone
  • Cementitious screeds and screeds made from special binders (Topcem and Topcem Pronto)
  • Concrete
  • Old bituminous membranes
  • Wooden trimmings
  • Galvanized sheet, copper, aluminium, steel and iron
• Ready-to-use coloured waterproofing product for external applications made from synthetic resins in water dispersion, and when dry forms a continuous, flexible, waterproofing membrane
• Resistant to all atmospheric conditions and UV rays, and guarantees long-lasting protection for the substrate
• Easy to apply using a long-piled 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
• Due to its flexibility, Aquaflex Roof is compatible with normal dynamic expansion and contraction stresses caused by temperature variations and vibrations
• Complies with the principles defined in EN 1504-9 (“Products and systems for protecting and repairing concrete structures: definitions, requirements, quality control and conformity assessment. General principles for the use of products and systems”) and the requirements of EN 1504-2 coating (C) according to principles PI, MC, RC and IR (“Concrete surface protection systems”).

Preparation

• All substrates, whether 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 affect adhesion
• 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% 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% water. If applied on existing bituminous membranes, carefully hydro-blast the surface, wait until the water has drained off and treat the surface with Aquaflex Primer
• 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 butyl rubber tape, or by bonding Mapetex 50 (h 20) 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, but mixing before use is recommended so that it is perfectly blended

Application

• Aquaflex Roof must be applied with a llong-piled roller, brush or by airless spray
• 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 crossways with respect 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
• Tools must be cleaned with water immediately after use
• Coverage rates:
  • Waterproof membrane: at least 2 kg/m²
  • Protective finish on bituminous membranes: approx. 0.5 kg/m² on smooth membranes. Approx. 0.9 kg/m² on mineral-filled membranes
  • The consumption rates indicated are for a seamless film on a flat surface and could be higher on uneven substrates and according to the absorbency of the substrate.

Limitations

• Do not use Aquaflex Roof if the temperature is lower than +5°C or higher than +35°C, or if it is about to rain
• Do not apply if there is dew on the substrate
• Do not apply Aquaflex Roof on wet substrate or on substrates with rising damp
• Apply Aquaflex Roof on surfaces without depressions or hollows and, where required, with the correct amount of slope
• Do not apply Aquaflex Roof on weak or dusty substrates
• Do not apply Aquaflex Roof on painted metal surfaces
• If it rains between one coat and another of Aquaflex Roof, wait at least 12 hours before applying the next coat, and always until there is no residual moisture; adhesion between the two coats could be affected
• Do not use on bituminous membranes that have only recently been applied (< 6 months)
• Always wait until the surface to be treated has completely oxidised
