Acriflex Rapido is the fast one: a water-based liquid waterproofing that films in 20 minutes, so fog and dew won't wash it out; keep rain off it until it's dry, about 4 hours at 23°C. It applies from +1°C below 70% humidity and films at up to 98%, helping with those shorter summer and coastal region work schedules. Two coats build a 1.5 mm elastic membrane with 160% elongation (ISO 527-1), for patios, balconies, roofs, flashings and foundation walls, tileable after 48 hours. It is also suitable for encapsulating cement asbestos.

    Frequently Asked Questions

    What is Acriflex Rapido used for?
    It's a fast-filming liquid waterproofing for roofs, terraces, balconies and foundation walls, and for encapsulating asbestos-cement. It films in 20 minutes, then resists fog and dew.

    Can it be used on asbestos surfaces?
    Yes. Acriflex Rapido encapsulates asbestos-cement when used with Acriflex Primer, then two crossed coats of Rapido in contrasting colours.

    How fast does it dry?
    It films in 20 minutes and then resists fog and dew. Keep it out of pouring rain until it's completely dry, about 4 hours at 23°C.

    Do I need a primer?
    It depends on the substrate.

    Use SBS-Bond when:
    • Waterproofing smooth bituminous or slated membranes

    Use Grip Primer when:
    • Applying over smooth, dry concrete, cleaned tile, existing floors or metal

    Use Acriflex Primer when:
    • Encapsulating asbestos-cement surfaces (Type A, B or C)

    Use WATstop at 1.0 kg/m² in two coats when:
    • The concrete is damp or rough, or rising damp is present

    No primer is needed when:
    • Coating untreated, dry and stable wooden surfaces

    How is it applied?
    By brush, roller, squeegee, or spray gun. Two coats, 4 hours apart at 23°C: 2.0 kg/m² for waterproofing, 1.0 kg/m² for asbestos encapsulation.

    Can it be used in cold weather?
    Yes, down to +1°C. It films in 20 minutes even at low temperature, and the cured membrane stays flexible at low temperatures.

    Is it UV-resistant?
    Yes. It passed 1680 hours of accelerated weathering (EN ISO 11507) and can be left exposed once dry.
