ROK Shield Application Instructions ROK Shield is a

ROK Shield Application Instructions ROK Shield is a non-toxic, water based chemical formulation that actually penetrates glass by filling in the structural pores. When clear Mylar film is placed onto the glass, ROK Shield bonds the glass and film together which converts ordinary glass into a high strength protective shield. ROK Shield has many uses. It protects against: § “Smash & Grab” type thefts § Projectiles during hurricanes § Blasts and fragmentation often associated with blast events. § Ballistic forces. ROK Shield can protect glass from most handguns† § Radio frequency and Infra Red intrusion †Different glass thicknesses and film combinations are used to achieve different protection levels. See a ROK PSI representative for more information.

Application Instructions ROK Shield should always be installed by ROK trained personnel. The instructions within demonstrate ROK Shield application onto sample glass only. Please contact a ROK PSI professional prior to installing ROK Shield onto a full sized window. Step I Using a glass cleaner product (or mixture of denatured alcohol and water), spray the surface of the glass and wipe clean. Ensuring to remove all loose debris, streaks, and other contaminants. Step II Wipe glass clean with lint-free cloth or towel, and spray glass cleaner onto glass a second time. Then using a flat razor/scraper†, draw it across the glass surface in smooth even strokes. Ensure that each new stroke is adjacent to the prior one so that the entire glass surface is scraped clean. If glass has roller stress, use a teflon scrub pad. This process removes all fine debris which is down in the open pores of the glass surface. Allow glass to dry thoroughly. †For Larger windows, use an Unger light duty scraper with handle extension 2313 W Sam Houston Parkway N Suite 105 Houston, Texas www. ROKProtective. Systems. com 77043

Step III Shake ROK Shield container for 60 seconds, and then onto glass surface. Ensure to coat entire surface so that glass is thoroughly and uniformly coated with ROK Shield formula. Then, peel release liner from pre-measured, pre-cut film. Spray ROK Shield onto the adhesive side of the film as the liner is pulled away. Step IV Seat film onto glass 2313 W Sam Houston Parkway N Suite 105 Houston, Texas www. ROKProtective. Systems. com 77043

Step V Wet the entire surface of the film with ROK Shield, and squeegee the film with a Thor’s Hammer type squeegee, (with Blue Max squeegee blade), which will cause it to bond to the glass. ROK recommends that the strike face of the film be coated with ROK Shield to prevent the film from being scratched. Step VI Starting at the top of the window using a Thor’s Hammer type squeegee, draw squeegee along the top edge of the film from one side to the other. Next squeegee from the top middle of the window straight down (about 2 feet when applying to an 8 foot window). Return to the top middle again and this time using diagonal strokes squeegee using downward overlapping strokes out to the left side of the center, and then to the right side. Continue this pattern until the bottom of the window is reached. The squeegee process must be done at a fast but steady pace to prevent the ROK Shield from drying out too quickly. DO NOT force air pockets and bubbles towards the center. 2313 W Sam Houston Parkway N Suite 105 Houston, Texas www. ROKProtective. Systems. com 77043

Step VII Trim film edges as necessary to fit to glass surface. ROK Shield should be allowed to cure for 72 hours. Allow initial layer of film to cure 24 hours before additional layers are placed onto original glass &film bond. Successive layers can be placed within 12 hours of each other. To place additional layer(s) of film onto original, repeat steps I through VII If any part of these instructions are unclear, contact ROK Protective Systems for questions related to the ROK Shield application process.
