Presto offers a complete line of restoration, protection, and cleaning products for architectural glass surfaces.
Windows on commercial buildings get severely stained due to various environmental conditions. Click here to learn about how and why architectural glass gets stained. The conditions that the architectural glass is subjected to can lead to surface damage, effectively etching the glass material. This often prevents the glass from being cleaned or restored by conventional means.
When glass has experienced corrosion, often referred to "stage 2 corrosion" the glass must be resurfaced in order to effectively remove the damage. We have developed a system to effectively sand down the surface of the glass, removing the stains, and renewing a highly polished surface. Presto's Glass ReSurfacer System is specifically designed for this type of application. After performing glass restoration, a high performance protective treatment should be installed, creating a polymeric barrier on the new glass surface. This barrier will help prevent future damage.
The Glass Defender Series is a combination of products designed for the protection of architectural glass surfaces. The polymers in the Glass Defender Series are high performance hybrid silicone materials. These materials are partially inorganic, and will not easily break down due to UV degredation. Typical glass protective treatments, on the other hand, consist of organic polymers that quickly break down when exposed to UV degredation. The polymers in our protective treatments cure, bonding to the glass surface, where they will remain almost indefinetally; unless abraded away by abrasive products. Once the glass surface is restored and protected, it should be routinely cleaned with products that are designed not to damage the protective treatment, or contribute to future staining on the glass or surrounding architectural surfaces.
While the Glass Defender Series is extremely durable, and can withstand common window cleaning detergents, soaps and chemicals, not every cleaning material has been tested in order to confirm compatability with the protective treatment. Scumfrees Professional Window Cleaning Concentrate is specifically design to clean windows without damaging the Glass Defender protective treatment. Additionally, Scumfrees dries to a powder so that in the event that any material is left on the building, it will not not attract stain forming minerals or environmental contaminates.
Scumfrees dries to a white powder that can be seen from from the ground to better help with quality control, and ensure window cleaning technicians are not allowing excessive amounts of material to remain on building surfaces. This forces window washers to do a better job at removing the window cleaning solution from the frames and other horizontal surfaces using towels or rags.
