The secret behind UltraBan’s success is its infusion film chemistry- The Invisible Shield. This shield will not allow mold or mildew to grow on this barrier film surface protecting the substrate below from fungal growth.This coating becomes one with the substrates by microscopically penetrating and crosslinking within the absorbent surface. This means that UltraBan bonds with the material unlike most products that lay on the surface and can be washed away. UltraBan is lab tested and more importantly, proven in the field to provide a long-lasting barrier against mold and mildew growth. After application, it will dry completely clear and will not change the look of the surface. It s perfect for the home interior or exterior above ground applications.
