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 Proffs is biodegradable.
