Water-repellent coating - 5l

Solvent-free water-repellent coating for mineral and other absorbent surfaces where rainwater causes soiling and deterioration of building materials by penetrating them, carrying dirt in with it and gradually saturating them with salts. The growing crystals of these salts then cause building materials to lose strength and gradually erode, and lead to efflorescence, dirty stains and overall soiling of the surface. - Does not create a glossy surface and does not change the appearance of materials - Prevents water from entering cracks up to 0.2 mm wide - Resistant to temperature changes, UV radiation and air pollutants *Coverage 6 m² / 1 L
