Hydrophobizing compound for imparting water-repellent properties to porous building materials. To protect facades, lime and cement plasters from atmospheric moisture and capillary suction. Purpose Crystallisol Hydrophobizator: It is used for processing porous building materials: concrete, brick, gypsum, wood, plaster. The walls of the pores and all particles of the material in contact with the water repellent are enveloped in an invisible thinnest water-repellent film. The processed material loses its ability to be wetted with water and to absorb it capillary. When the composition is applied to the surface, a thin layer of polymer is formed on the pore walls, which is not wetted with water and does not allow water to penetrate into the pores. Crystallisol Hydrophobizator leaves the pores open, and the vapor permeability of building materials remains almost at the original level. Due to the device of a hydrophobic barrier, the material acquires water-repellent properties that persist for a long time, increasing its resistance to pollution and mold damage. When processing the facade, it is recommended to carefully apply the material to the surface, avoiding contact with glass, plastic window frames and other parts of the structure that do not require processing. Before applying, cover such places with paper, construction tape. Description Crystallisol Hydrophobizator: An aqueous solution based on methylsiliconates, which, penetrating into the pores of the structure, protect it from capillary inflow of water by changing the contact angle of the surface wetting. Properties Crystallisol Hydrophobizator: Possesses high chemical resistance and resistance to weathering. Does not form a surface layer. Does not prevent moisture evaporation from the material. Gives water and dirt repellent properties to materials. Retains the color and texture of the surface. Fireproof. Carry out work in dry weather at a temperature of at least + 5 ° C. Material consumption: 1 liter of concentrate - 155 m² of surface. Packing: polyethylene canister 1 l.
