Moisture is the root cause of almost all mechanisms that damage mineral building materials. The porous nature of mineral substrates soaks up the water containing contaminants via capillary suction. This can potentially damage the material in visually displeasing ways. Preventing water ingress into a substrate structure can completely eliminate risk of damages to the substrate caused by moisture. NANOSTONE products prevent moisture to enter the substrate but sustain vapor permeable properties of it. Nano-protection is completely resistant to UV radiation, scratches and high amplitude of temperatures. Water repellent nano-particles of NANOSTONE are smaller than the pores of the substrate. Due to this and the low viscosity, they penetrate deep into the building material and chemically bond to the inner pore walls, rendering the substrate hydrophobic. External water is kept from entering the pores, while water vapor generated from within the structure can still escape. The structure remains breathable. NANOSTONE water-repellent products create long-lasting protection (up to 15 years) from negative environmental effects such as: freeze-thaw damage, corrosion, salt burst, florescence, and acid rain attacks. Hydro-phobic Nano-coating combats these problems; not only it increases the longevity of treated structure, but also decreases maintenance costs. Hydrophobic Nano-coatings are ideal for building facades, walls, any other outdoor surfaces, and also historic landmarks and monument you would want kept undamaged.
