Remove mosses, lichens and algae with our Biocidal-Wash

The growth of mosses, lichens and algae can cause many different problems to a range of surfaces. That’s why we supply a high-quality biocidal-wash to combat algae and moss growth. The biocidal-wash destroys all micro-organisms. This is due to its synergistic formulation which displays a large spectrum of activity and maximum efficiency of treatment.

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. Any residual debris can be removed using most wire brushes and pressure washers.

Removing green algae from your natural stone paving can be very time consuming. Clean your paving with our professional quality moss and weed killer to save time and money. The concentrated formula of our moss killer for block paving means you get more cleaning power in a smaller package.

As a moss killer for block paving, the Kingfisher Biocidal-Wash is very effective and will always impress. It is suitable for a wide range of materials which includes brickwork, tile, stone and much more. We have a wealth of experience developing professional roof and surface cleaning products, ensuring effective and reliable products.
