Dulux Trade Weathershield Fungicidal Wash for Masonry and Wood

Ready-to-Use Preparation Wash:

Dulux Trade Weathershield Multi Surface Fungicidal Wash is a water-based, ready-to-use treatment formulated to kill mould, algae, and lichen on exterior surfaces before re-decoration. It requires no thinning and is suitable for application on both bare and painted wood and masonry. One or two coats applied by brush will treat contaminated surfaces ahead of any suitable Dulux Trade Weathershield topcoat.

Coverage and Drying:

The wash covers up to 25m² per litre under normal conditions, though coverage will vary depending on the absorbency of the surface being treated. It is touch dry within 2 to 4 hours. Leave the product on the surface for a full 24 hours, then rinse thoroughly with clean water to remove dead growth and residues before proceeding with decoration.

Safe and Compliant Application:

COSHH Regulations 2002 apply to its use. Store away from extremes of temperature and protect from frost.
