Fungicidal Wash is perfect for helping to prepare a substrate prior to applying our EWI or render systems. The product takes just 24 hours to kill all microorganisms on the substrate, including algae, mould and lichen. The wash can be applied using either a brush, sponge or cloth.
Fungicidal Wash can be used internally or externally on many different surfaces including brickwork, stone, wood and plaster. The active ingredient in the product is Benzalkanium Chloride, a proven biocide. Not suitable for adding to paints, primers or renders – the wash should be used as a standalone product.
