Dulux Weathershield Fungicidal Wash

Dulux Weathershield Fungicidal Wash is a specialist surface treatment formulated to clean and treat bare or previously painted wood and masonry affected by biological growth such as mould, algae, and fungi. It is an essential preparatory product in the Weathershield system, ensuring a clean and stable surface prior to painting.

This product is suitable for application by brush or low-pressure (non-atomising) spray only, helping to minimise airborne particles during use. Its use is recommended to prevent the recurrence of organic contamination and to promote adhesion and longevity of subsequent coatings.
