Wall materials such as clinker masonry, brick masonry, natural stone, external plaster, concrete, fiber cement or limestone are stable but not indestructible. Outside, walls are exposed to direct weathering from snow, wind and sun. For a longer service life, outer walls therefore need a breathable seal to prevent moisture. The W870 wall impregnation stops the penetration of moisture and rain. The driving rain can roll off and water vapor can escape from the inside. This reduces the formation of green deposits and has an anti-pollution effect. So your wall is effectively sealed and protected from external influences.
