• It creates a water repellent surface that prevents capillary penetration of rain and splashes of water into the structure.
• Allows water vapour coming from inside the structure to pass through.
• Reduces salts moving to the surface of the structure.
• Does not form a superficial film.
• Reduces the growth of algae, green discolouration and prevents frost damages.
