Product details

Grean Boss is a 4 litre treatment for green deposits and surface deposits on roof tiles and other hard surfaces. The formula is safe to use on clay, concrete and slate roof tiles, including flat roofs, and it can also be applied to patios, garden paths, tarmac and resin driveways.

It is designed to penetrate deeply and let rain wash the treated surface over time. The product is safe, biodegradable and acid-free.

  • Treats up to 100m²
  • Heavy application: dilute 1:2 for up to 60m²
