How does it work? - Self-Clean paint creates a microscopic textured surface with a contact angle of 140 degrees, resulting in an ultra-hydrophobic surface that causes water to bead up into pearls of water that run across the surface of the facade. As beads of rain water run over the surface of the faÄ“ade, they collect dirt and contaminants lying on the surface of the paint and remove them, cleaning the facade as it rains.
