This procedure eliminates further contamination by active spores to surrounding areas during surface preparation. It is advisable to treat persistent stains caused by fungal growth with a further coat of Fungicidal Wash solution and 24 hours should be allowed prior to painting. Clean all equipment immediately with water after use.
