Protectosil® 100 NK
Protectosil® 100 NK is suitable for waterproofing of porous mineral building materials.
Scope of Application
Suitable solvents: Ethanol* (water free, denatured with petroleum hydrocarbons) Aliphatic hydrocarbon solvents (pentane, hexane, heptane, etc.) Aromatic hydrocarbon solvents (toluene, xylene) White spirit Dilutions of from 1:1 to 1:9 are possible (Dilution of Protectosil® 100 NK and solvent) * recommended solvent Suitable porous, mineral substrates: Concrete (fresh or carbonated) Clinker masonry Ceramic tiles Sand-limestone Natural stone Cement render Product Characteristics solvent-free low volatility high reactivity very good beading effect water vaporpermeable, colorless impregnation seals hairline cracks up to 0.3 mm considerably reduces absorption of water and damaging water-borne salts (e.g. chlorides) very good penetration capacity very high alkali resistance stops the alkali-silica reaction The substrates to be treated should be air-dry and clean in order to ensure deep penetration of the active ingredient. During application, the outside temperature and the temperature of the substrate should be in the range from 0 °C to 40 °C. The material should not be applied if there is strong wind or if it is raining. Protectosil® 100 NK must not come into contact with water either before or during use. Protectosil® 100 NK must be applied by flow coating to the saturation point. This is achieved by allowing it to flow without pressure against the surface to be treated. All liquid delivery devices are suitable (airless spray guns, for example). The material must not be atomized. Protectosil® 100 NK must remain in contact with the substrate for several seconds as a liquid film. Horizontal surfaces should have a shiny, wet appearance for 3-5 seconds. Vertical surfaces should exhibit a 30-50 cm shiny curtain of liquid.
