Dulux Trade Weathershield Fungicidal Wash in a 5 litre container is used for preparing external masonry, render, brick, and previously painted surfaces ahead of redecorating. The wash is formulated to tackle surface growths such as mould, algae, and lichen that often occur on building exteriors.
Typically applied by brush, roller, or spray, it helps remove organic residues prior to the application of masonry paints or other finishes. This treatment assists in creating a clean surface, supporting better paint adhesion and a more consistent final appearance on site projects.
