Green algae on your patio, paths, or walls not only looks unsightly, but can also cause slipperiness and unsafe situations on paved surfaces. Algae grow quickly in damp periods and leave behind a stubborn green haze that is difficult to combat with water alone. HG Green Algae Remover supports you in effectively removing this growth and also offers long-lasting protection, so that your outdoor space remains clean and well-maintained for months.
- Long-lasting protection: After treatment, the surface is protected against new algae growth for months.
- Widely applicable: Suitable for patios, paths, walls, roofs, terracotta pots, and gravestones.
- Efficient consumption: One litre is sufficient for 100 to 200 m2, depending on the surface.
- No harmful after-effects: Does not leave behind substances that make rinsing necessary.
How it works
This agent works on the basis of N,N-didecyldimethylammonium chloride, an active substance that tackles algae to the core. By treating the surface in dry weather, the agent gets the chance to penetrate and break down the green algae. Because the product leaves behind a small residue that adheres to the surface, the return of green algae is delayed for a longer period, which contributes to the preservation of your materials.
