The testing was designed to demonstrate how SelfClean would keep a section of the concrete surface free of mold after pressure washing. However, HCPS officials were not able to pressure wash before the test date. Nonetheless, we continued the treatment without pressure washing and SelfClean still continued improving the concrete surface over 8 months. This test demonstrates the effectiveness of SelfClean using sunlight, wind and rain to breakdown the existing mold. SelfClean will continue to breakdown mold for several years. Also, the untreated surface adjacent to the treated SelfClean surface over the 8 months developed mold.
