Agent Blue Moss & Mould Control

Moss, mould, lichen, and algae don't just look bad - they damage the surfaces beneath them.

Left untreated, biological growth breaks down roofing materials, stains masonry, weakens concrete, and shortens the lifespan of almost any outdoor surface. New Zealand's damp climate makes it worse, spores travel freely on the wind and attach to virtually anything.

Agent Blue is Stratacote's proven biocide solution - bleach-free, fast-acting, and effective on a wider range of surfaces than most competitors. Trusted by contractors, councils, and homeowners across New Zealand, it works on roofs, driveways, pathways, fences, walls, lawns, and more. Choose from homeowner-ready formulations or contractor-strength concentrates depending on your project size.

Moss, mould, algae, lichen and liverwort are members of the Byrophyte family, they don’t have a root system and breed via spore transmission, and spores travel freely over great distances in the wind. They can attach to almost any surface and damage the host substrate in the process.
