A fungicidal wash for cleaning wood and masonry surfaces prior to painting.
To get the best results, remove as much mould, algae, lichen or moss as possible by scraping and brushing, before treating with Dulux Trade Weathershield Multi-Surface Fungicidal Wash.
Apply the solution by brush only to all affected areas.
Leave for 24 hours and then thoroughly rinse and scrub with clean water to remove residues and dead growth.
When the surface is fully dry, apply the appropriate Dulux Trade or Dulux Trade Weathershield finishing system.
After use, remove as much wash as possible from brushes before cleaning with clean water.
