Why use Muckoff before coating?

Applying a roof coating or waterproofing system over moss, mould, or algae is one of the most common causes of premature coating failure. Muckoff eliminates biological growth at the source, ensuring your surface is clean, stable, and ready to bond — giving your Speciality Coatings system the best possible foundation for long-term performance.

Environmentally Responsible

Muckoff uses a biodegradable, organically derived formula — effective on biological growth without the environmental impact of harsh chemical treatments. Safe around plants and gardens when used as directed.
