I treated and coated an asbestos roof in my garden shed that i share with my neighbor.At the end both of us were very pleased with the results, the roof is now safer as the coating provide good encapsulation and it looks nice too. The job was carried about 1 year ago and the coating looks still as a new."

‣ Remove mould, algae, moss & lichens from external walls
‣ Restores colour of existing external surfaces
‣ Improves adhesion quality of decorative coatings
‣ Concentrated formula gives you more cleaning power in a smaller package

Kingfisher Biocidal-Wash is a deeply penetrating aqueous biocide solution which removes moulds, algae, moss and lichens from external walls. It can be used to restore the colour of existing external surfaces or as a preparation to improve the adhesion quality for a proposed decorative coating.

The biocidal wash destroys all micro-organisms due to its synergistic formulation which displays a large spectrum of activity and a maximum efficiency of treatment.

The concentrated formula means you get more cleaning power in a smaller package. Dilute 1 part Biocidal Wash with 4 parts clean water then apply using a brush a low pressure spray ensuring thorough wetting. Leave for 5 or 6 hours or preferably overnight for full biocidal action to develop and then remove any residual debris by brushing or power washing.

Quality Product

Good quality product and I always receive a great service and fast delivery from Kingfisher. We use this product for driveways and patios and always get great results.

Stone Patio

Made a remarkable difference to some very green sandstone flags, in conjunction with a domestic pressure washer. Has brought the patio into a 'as new'' condition and hopeful it will stay that way now.
