AquaDry RainForce – water-based siloxane masonry water repellent

A ready-to-use, high-performance siloxane water repellent for treating above-ground exterior masonry against penetrating damp from rainfall, while preserving the natural appearance of the surface.

Key benefits

  • Protection for up to 3 years
  • Water based – multi-functional siloxane technology
  • Excellent penetration depth and tack-free drying

Suitable substrates

Concrete, roughcast, sandstone, brick, natural and synthetic stone and aerated concrete. Not for new or recently pointed work (too alkaline).

Application

  • Clean dirty surfaces with BIOKIL. Biocidal Cleanser 2–3 days beforehand (no detergents). Apply above 5°C with no rain forecast for at least 24 hours.
  • Apply by low-pressure, large-particle spray or brush, aiming for a 300mm run-down on surfaces of average porosity.
  • A second coat is required once the first has dried; a third may be needed on highly porous surfaces.
  • Curing begins within 24–48 hours; full water repellency after approx. 7 days.

Coverage: 2–5m² per litre per coat; minimum 2 coats. Available in 5L and 25L containers. Do not allow to freeze; use within 12 months. Wear eye/face protection.
