Q: Does PURETi Clear treated glass mean that I never have to wash my windows again?
A: No, but glass treated with PURETi Clear needs to be cleaned HALF as often and it’s TWICE as easy
when it’s done.

Q: How long will PURETi Clear last?
A: When applied properly, PURETi Clear will deliver its remarkable benefits for up to three years.

Q: Can PURETi Clear be seen on glass?  
A: No. PURETi Clear dries to form an invisible, transparent mineral film.

Q: Do glass surfaces need to be clean before PURETi Clear is applied?
A: Yes. PURETi Clear is a keep-it-clean glass surface treatment, not a cleaning system. It proactively breaks up all organic matter at the surface.

Q: What kind of light is needed for PURETi Clear to work?
A: PURETi Clear is activated by ultraviolet light, and more specifically the UV-A range of light. Sources of
UV-A light include: direct sunlight, ambient light (found on cloudy days or in the shade) and artificial fluorescent light.

Q: How much light is needed?
A: The strength of light is measured in watts per square centimeter or mW/Cm2. To experience the full self-cleaning benefit of PURETi Clear 0.10 mW/cm2 is required. The strength of direct sunlight (1.2-2.0 mW/cm2) or ambient light (0.5 mW/cm2) is more than enough to activate PURETi Clear’s self-cleaning benefit.

Q: How is PURETi Clear applied?
A: CSG has developed a customized electrostatic spray system that has been optimized to apply PURETi products in the best possible manner. Glass surfaces are treated by applying one coat of PURETi’s protective basecoat first, and then spraying on one coat of PURETi Clear.

Q: How long will it take for PURETi Clear to dry?
A: 5-10 minutes.

Q: How long does it take for PURETi Clear to start working?
A: 4-7 days.

Q: Will PURETi Clear work indoors?
A: Yes. When applied to indoor glass surfaces, PURETi Clear will eliminate organic malodors and significantly reduce air pollutants such as VOCs when sufficient UV-A light is present. However, there isn’t a sufficient amount of light indoors to activate PURETi Clear’s self-cleaning benefit.
