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, especially not with soap or water. The surface must be dry and clean from all debris.
Shake and mix the 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 the product in a circular, overlapping motion to ensure the 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 best results. Fold the towel into squares using a clean area of the rag every couple of minutes until 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 type of cleaning solution for 72 hours.
If a second coat is required. The second application should be performed with a clean and dry window cleaning brush and squeegee. Use the window cleaning brush to apply the product. Before the material dries on the glass, a dry window cleaning squeegee can be used to remove excess material. If the material starts to dry, add more product to loosen the dry material for easy removal with the squeegee. This application may eliminate the need for polishing the window. Clean excess residue from edges and frames with a rag. When using a squeegee to remove the product, carefully capture excess material with the product applicator. This technique should only be attempted by an experienced window-cleaning professional with advanced squeegee skills. Also, this process is only suitable for the second application. Perform subsequent applications immediately after the first. 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 may come into contact with the glass during that time.
Any wet rags that are laden with material may be flammable. Special precautions should be taken to protect these items from exposure to an ignition source.

Glass Defender: 5 years
The performance warranty of this product is dependent on three factors:
- 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 excessive UV rays, constant exposure to water or harsh chemical applications, reapplication may 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 warranty states that when this product is used following the application instructions outlined in this document, and not exposed to conditions outside of the documented Environmental Conditions Form filled out before purchase, and provided no harsh chemicals or abrasives have been used to damage or abrade the protective coating, the glass surface will be protected from previously identified stains that cannot be removed with standard cleaning procedures for a period of 5 years.
The length of warranty is to be determined by Presto after examination of the Environmental Conditions Form.
