Our technicians use Presto Restoration Products and are equipped with the proper tools, knowledge and experience of “how to” remove scratches, stains and all other types of surface damage to architectural glass surfaces. These products, tools and expertise are available online at www.PrestoRestorationProducts.com or by calling them directly.

When concrete makes contact with glass, it is difficult to remove. The common industry standard for removal of concrete residue is to use a stainless steel scraper blade lubricated with a window cleaning detergent mixture. Presto Restoration Products developed new techniques that effectively remove concrete residue without scratching the glass surface. Presto Restoration Products developed a product called Glass-Crete that is a proprietary formulation containing phosphoric acid and acid compatible polymers. The phosphoric acid will break down calcium in the concrete without affecting the glass surface in any way. These specialized polymers help lubricate the surface, help prevent scratching when removing concrete. These polymers remain on the glass surface and help prevent adhesion of concrete that makes contact with glass in the future.


The picture below is of six technicians removing concrete on a high rise building after a concrete pump line exploded. This happened while it was raining and concrete slurry ran down the entire buildings glass and anodized aluminum structure. This happened twice in one month.

Scrapers should never be used to remove concrete from glass, as they will certainly scratch the surface by trapping abrasive concrete particles under its metal blade and dragging them along the surface.

Once concrete or its slurry coat is removed from glass surfaces, most times there will be mineral stains present. These mineral stains will need to be removed by method of wet sanding the glass surface to remove the top layer. This is due to the minerals found in concrete, mainly silica, fusing to minerals in the glass and creates a tenacious bond. This can easily be performed using the Glass ReSurfacer System. This system will remove light scratches that may have been caused by concrete removal. Once glass is completely restored, we apply a protective treatment that will help prevent the adhesion of mineral-based stains such as concrete. As well, protect against other types of stains and scratches due to the high performance polymeric barrier in-between the glass surface itself and damaging elements.

Architectural glass was designed to have a highly polished and 100% optical distortion free view for the eye to focus on the other side of the window, without any obstructions or distractions in view. While glass is an extremely durable surface, it is susceptible to environmental issues, changes in appearance by a number of processes such as acid burns, oxidation, water erosion, ion exchange and abrasion. Additionally, glass surfaces can become contaminated with stains caused by caulk residue, oily window cleaning detergents, minerals from tap water, soap scum and paint, just to name a few. Each type of damage or stain listed above can be removed by using the Glass ReSurfacer System, which utilized the Glass ReSurfacer Final PolishThe Glass ReSurfacer System will completely remove these types of damage on any glass surface by revealing a new glass surface.

Once a virgin glass surface has been applied to glass, it is important to seal it with a high performance protective treatment that will fill in the minuscule cracks and valleys of glass and create a polymeric barrier to protect it. One such product is The Glass Defender Series consisting of an MD, HD and a Primer depending on the level of protection desired. In most cases, Glass Defender MD is used standalone by simply applying it to glass, and polishing with a micro fiber towel. Presto’s protective treatments utilize high performance silicone materials that cure to a strong polymeric film invisible to the naked eye. As well, these materials are partially inorganic similar to glass itself and will be as permanent as the glass surface.

Presto Restoration Products also has a product that can be easily applied on exterior glass that will prevent adhesion from abrasive materials such as concrete and will lubricate glass surfaces to help prevent scratching during the construction clean up process. This product is invisible and does not need to be removed like other glass protection products. Call us to find out more about these revolutionizing products.
