Product Details
Glass Defender is a high-performance, invisible coating that protects glass from damaging elements and helps to prevent scratching for up to five years.
Intended Use
Glass Defender is designed for all glass surfaces, including plate or tempered glass. This product is not suitable for use in areas where food may come in contact with the protected glass.
Recommendations
To maintain the glass after using Glass Defender, clean only with deionized water 2-3 times annually. Oily residues in typical surfactant-based soaps and detergents attract and glue a variety of environmental contaminants to building surfaces, causing stains.
Glass Defender is a proprietary blend of high-performance, partially inorganic polymers. This product provides an invisible coating that protects plate or tempered glass surfaces for five years against most types of stains and minor scratching. At a microscopic level, this product cures to a hard rubberized coating. This invisible coating is backed by a 5-year warranty. Glass Defender will also help protect glass from stains caused by adjacent oil-laden stone, such as precast sealed with organic water repellents (i.e., 40% silane).

Application
Use protective gear, and prevent personal contact with these products. Do not apply this material to glass when surface temperatures are above 122°F or below freezing.
Never apply this product with an applicator that has been used with other products or solutions, and especially not with soap or water. The surface must be dry and free from all debris.
Shake to mix product vigorously. Apply Glass Defender products with a spray bottle or sponge. Use the sponge to thoroughly work the product into the surface of the glass. Spread product in a circular, overlapping motion to ensure product coats the entire surface. For best results, thoroughly work the product into the surface so that it forms a cloudy film. Polish the surface with a microfiber towel to remove excess residue. A multi-step fold process should be used for the best results. Fold the towel into squares and use a clean area of the rag every couple of minutes until the excess material has been removed. Leave as much residue as possible while achieving the desired level of clarity. Material residue may not be seen on the glass unless viewed in direct sunlight. Never attempt to clean the residue with water or any cleaning solution for 72 hours.
For best results, apply two applications of the product to the glass. Apply the second product 24 to 48 hours after the first coating. If the area is not completely covered, untreated areas may be noticeable as the glass ages and stains develop there.
The product will start to cure within 1 hour. The protective coating will not fully cure for 72 hours. No liquids or rain may come into contact with the glass during that time.
Any wet rags that are laden with material are flammable. Special precautions should be taken to protect these items from exposure to an ignition source.
Precautions
SURFACE PREPARATION
Protection performance warranties are contingent upon using either Presto’s Glass ReSurfacer Final Polish to prepare the glass surface immediately before applying Glass Defender. Remove all dirt from the surface. The level of protection will be sacrificed if all contaminants are not removed before use. Be sure to polish the glass surface with a rag to remove all restoration product residue. Do not use detergents on the glass between the restoration and the application of Glass Defender products. Apply the product immediately after the glass restoration process has been completed.

Warranties
The information provided by Presto for the safe and effective use of this product, and all of our products, is believed to be good and accurate. However, due to the many different possible applications of this product, careful consideration should be made when selecting its suitability for each surface.
The information provided should never be substituted for individual testing to ensure the product’s compatibility with each surface intended for use. The purchaser shall assume all responsibility for determining the suitability of this product. When used as intended, this product will perform as stated. No other warranty can be made for this product, verbally or in writing.
Presto warrants this product to be free from defects. In the event this product is found to be defective, we will provide a sufficient amount of product to replace the defective product.
Glass Defender: 5 years
The performance warranty of this product is dependent on three factors:
- The combination of products selected
- Strict adherence to the application instructions
- Exposure to damaging environmental conditions
In normal conditions, these products will last as stated. In situations where the products are exposed to abrasion, constant exposure to water, or harsh chemical applications, reapplication will be needed more frequently. The length of time for which the surface will remain protected is directly related to its amount of exposure to damaging elements. It is the responsibility of the purchaser and/or the purchaser’s exterior maintenance service provider to monitor protected surfaces and determine the necessity of reapplication. It should also be considered that the glass on different sides of a building will age differently due to sunlight exposure. Typically, the coating on the north side of a building will last longer than the same coating on the south side of the building and require reapplication less frequently.
This product does not make the glass self-cleaning. Mineral stains caused by precast runoff, hard tap water, or other environmental contaminants can still develop on the protected surface. However, these stains will be easier to remove because the protective barrier prevents direct contact between the glass surface and the contaminants.
This warranty states that when this product is used in accordance with the application instructions and provided no harsh chemicals or abrasives have been used to damage or abrade the protective coating, the glass surface will be protected from previous stains for a period of 5 years.
