WEED AND ALGAE REMOVER GREEN-FREE

Usage Area: For combating algae on painted, treated, and untreated surfaces of wood, plaster, stone, brick, concrete, asbestos cement, sheet metal, roofing felt, plastic, etc.

Properties: Growth dies immediately upon treatment, loses its color, and starts to detach from the surface. On roofs and other weather-exposed surfaces, remnants are washed away by rain over time. The effect can be seen quite soon after treatment, but it might take 1–2 years for all remnants to disappear. The establishment of new growth depends on external conditions—shady and moist surfaces often experience growth faster. Repeat treatment with visible growth or once a year. Grön-Fri Direkt is biodegradable.
