Waterproof, water-resistant, antimicrobial (against mold, moss, algae, fungi and bacteria) hydrophobic coatings offer a permanent solution to prevent bridge damage, dirty facades, stone corrosion on monuments, frost damage and graffiti on public walls in the protection of buildings and monuments. Building cleaners, monument preservationists, cities and municipalities benefit from the value retention and the self-cleaning, super-hydrophobic or ultra-hydrophobic properties of ceramic nano-coatings and sealants. Nano-protection against mold, moss and algae preserves the clean appearance of natural stones (sandstone, granite, marble, limestone, slate, basalt, travertine) as well as concrete, clinker, clay (roof tiles) and composite materials (composite bricks) for decades, especially in regions with high humidity. Due to the small size of the molecular structures, they are also suitable for deep hydrophobic treatment. Sustainable fields of application are facades, facade paints, monuments, world heritage sites, historical buildings, castles, fortresses and churches, mosques and temples.
