Self-Cleaning Coating

Sto Corp.’s iQ Technology Coatings, including StoColor Lotusan (pictured), StoColor Climasan, and StoColor Dryonic, reportedly help protect against environmental degradation. According to the manufacturer, StoColor Lotusan creates a microtextured and hydrophobic surface that has only a small contact area for dirt and water—allowing dirt to be easily carried away by rain—and that protects facades from algae and fungi. According to the manufacturer, Sto iQ Technology coatings also protect against air pollution, temperature damage, and UV-light damage. Pricing varies. stocorp.com
