Before you apply WindowGrip™, GAM recommends reading
the instructions and applying a small test piece to familiarize yourself with the material and the application process.
Clean window with a non-ammonia cleaner before installing
WindowGrip™. This is particularly important if you intend to
shoot through the window and want maximum clarity or if you intend to leave WindowGrip™ on the glass for extended periods. For best results, apply to inside of windows.
Measure & test fit WindowGrip™. After measuring the window, unroll WindowGrip™ and cut it 1/8" larger than the area to be covered, leaving material to trim for a precise fit. Wet window with a spray bottle containing a solution of a few drops of Joy™ liquid dish detergent per 34 oz (or 1 liter) of distilled water.
Remove clear backing liner from WindowGrip™ to expose
adhesive, being careful to avoid creasing it. To remove the backing liner more easily, align two pieces of cellophane tape on opposite sides of the same corner of the WindowGrip™ sheet, leaving a short length of tape overhanging the sheet. Press the two overhanging pieces of tape together and then pull them apart quickly to pull the sheet from its liner. Remove the backer diagonally from one corner towards the opposite corner being careful
not to fold, wrinkle or touch the adhesive side against other surfaces, and discard it. Spray the adhesive side of WindowGrip™ with water & detergent solution before applying to window.
Thoroughly wet glass with spray bottle and starting at the top of the window, apply WindowGrip™ using a hard rubber squeegee to remove water between the sheet and the glass. Also spray nonadhesive side to ease the squeegee's travel. Apply it gently, taking extra care in the corners to avoid wrinkles and creases. Gently push any air bubbles out to the edges with squeegee.
