PURETi light activated, water based, surface treatments are spray applied to transform virtually any surface into a sustainable, self-cleaning material that proactively eliminates grime and foul material buildup, improves air quality, and eradicates organic malodors. Powered by the most advanced water-based UV-PCO (ultraviolet photocatalysis) technology available today, PURETi uses the light, not chemicals to create sustainable, clean surfaces that benefit the environment in ways never-before seen. PURETi treated surfaces need to be cleaned HALF as often and cleaning is TWICE as easy when its done. Reduces cleaning maintenance costs by 50% and reduces the water, energy, chemicals and labor expended in cleaning. Significantly improves indoor and outdoor air quality by continually eliminating VOCs and harmful green house gases such as Methane and NOx. Actively reduces levels of smog when applied to outdoor surfaces such as cement and building facades. Eliminates stubborn organic malodors such as smoke & human and agricultural waste. Creates a super-hydrophilic surface, causing water to sheet away any non-organic residue. Applicable to virtually any surface including: cement, stone, ceramic tile, painted walls, plastic, and metal. One professional application is warranted to last 5 years.
