Surface water-repellent product

Colourless coating, solvent siloxane based, it can be used to protect absorbing walls made of tiles, stone, cement etc. from water rain infiltrations. it does not alter the colour of the wall, it protects from ice and it stops humidity penetrating; it allows the evaporation of water inside wallings and deeply permeations also on slightly humid materials. ADVANTAGES • do-it-yourself • long-lasting water-repellent • permeable to water steam USES Water-repellent impregnation into mineral- based building materials. With a low molecular weight, BBK penetrates well and allows a very deep permeation. The permeation is invisible, very stable to limestone, permeable to steam. Preliminary treatment against carbonation of concrete on façades. Water-repellent and colourless shield for historic buildings or with particular architectural value. Water-repellent treatment for walls and bricks on façades, natural stones or not glazing baked clay. APPLICATION Ready to use 1. Clean up accurately the surface to treat. With old surfaces, the kind of washing depends on the kind of dirt; generally washing with cold water is sufficient. Without dirt, wash well with broom and dust with air.

Apply a first abundant coat by brush or spray to assure the total covering of the surface. 4. Apply a uniform second coat even if the first one is not yet completely dry. 5. Repeat the application until saturation. For a complete permeation apply 2-3 coats at a distance o 2 hours one from an other. 6.You will obtain the best impregnating effect when the base is very dry and absorbent TECHNICAL DATA Aspect Transparent liquid Odour Solvent UV-Rays resistance 1000 hours without remarkable changes Wearthering test resistance 2000 hours without remarkable changes Inflammability Inflammable Steam permeability (High transpiration) μ =7 YIELD Bricks: lt/m² 0,3-0,4.
