Aquaflex Roof Plus is a ready-mixed liquid waterproofing membrane developed by the MAPEI R&D laboratories. It is an innovative system made from synthetic polyurethane-acrylic resins in water dispersion containing no solvents and no VOC.
When dry, Aquaflex Roof Plus forms a seamless membrane that can extend more than 350% and is resistant to atmospheric agents and UV rays, guaranteeing a long service life for the substrate.
Aquaflex Roof Plus adheres strongly to numerous types of substrate and, thanks to its high elasticity, is compatible for roof structures exposed to normal dynamic stresses. Due to its special formula, Aquaflex Roof Plus has excellent mechanical properties that remain stable over the years.
Aquaflex Roof Plus is easy to apply by brush, roller or spray on horizontal, vertical and sloping surfaces. The product dries very quickly and several coats may be applied in a very short space of time to reduce site waiting times to a minimum. Aquaflex Roof Plus also has a special solvent-free finishing cycle incorporating Mapecoat TNS Urban and Mapecoat TNS Protection so that roofs may be accessible to foot traffic.
Aquaflex Roof 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 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
- Remove all loose parts from concrete and mineral-based substrates. Repair any hollows in the surface with Mapeslope. Prime the surface with a coat of Aquaflex Roof Plus 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. Fill any gaps between ceramic floor tiles with Adesilex P4 before applying Aquaflex Roof Plus
- On non-absorbent ceramic substrates, apply Eco Prim Grip, synthetic acrylic resin adhesion promoter with silica aggregates
- For all other types of substrate, prime the surface with a coat Aquaflex Roof Plus diluted with 10% water
- When applied on old bitumen membranes, carefully hydro-blast the surface, wait until the water has drained off and prime the surface with Aquaflex Primer, synthetic resin-based primer in solvent solution
- When applying the product on metal substrates, thoroughly clean the surface and apply a coat of Eco Prim Grip primer
- Before applying Aquaflex Roof Plus, pay particular attention to expansion joints and fillets between horizontal and vertical surfaces, which must be waterproofed with 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 Plus
- 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
- After preparing and priming the substrate, apply Aquaflex Roof Plus with a long-piled roller, brush or by airless spray
- Apply at least two coats of Aquaflex Roof Plus to form an even layer. Apply each crossways with respect to the previous coat
- Various stratigraphic layouts with increasing durability may be obtained by applying Aquaflex Roof Plus in different thicknesses and at different consumption rates; refer to the product data sheet for further information
- If there are micro-cracks in the substrate, and around overlaps in bituminous membranes or for systems in durability classes 10 or 15 years, incorporate Mapetex 50 non-woven polypropylene fabric between the various layers of Aquaflex Roof Plus as follows:
- Spread a generous coat of product on the substrate, and while gradually applying the product, immediately lay Mapetex 50 and go over the surface with a flat spreader or spiked roller to ensure it is perfectly wetted
- When this layer is completely dry apply the next coat of Aquaflex Roof Plus, to cover completely Mapetex 50
- Clean tools used to apply Aquaflex Roof Plus with water before the product dries
- Coverage:
- Protective finish or reflective coating on an old bituminous membrane: approx. 0.9 kg/m²
- Waterproof membrane: 2 kg/m² (for a 1 mm thick dry layer)
- In general, the consumption rates are for a seamless film on a flat surface and will be higher on uneven substrates
Limitations
- Do not apply Aquaflex Roof Plus if the temperature is lower than +5°C or higher than +35°C or if it is about to rain
- Always incorporate Mapetex 50 reinforcement in the membrane on roofs exposed to particularly low temperatures
- Do not apply if there is dew on the substrate
- Do not apply Aquaflex Roof Plus on wet substrates or on substrates with rising damp
- Do not apply Aquaflex Roof Plus on painted metal surfaces
- If it rains between one coat and another of Aquaflex Roof Plus, 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
