1. Film should be applied to INSIDE surface of standard 1/8” single and dual panes. This includes exterior removable storm panes, and all window shapes such as patio and French doors, trapezoids and arches.
2. Do not apply these window films to the following surfaces:
Motor vehicle windows
Frosted, etched, leaded, cracked, holed, or deeply scratched glass
Any otherwise flawed or defective glass or glass that is over 40 years old
3. Apply film when the temperature is between 40° and 90°F for at least three days.
4. Handle the film very carefully to prevent creasing.
5. Installing window film on larger windows (3-4’ wide) is easier with two people.
Here are the tools needed when installing window film.
Application Solution used for the application and cleaning process. Make a mixture of water and no tears baby shampoo (without conditioner). Mix one quart of water and ¼ teaspoon of shampoo in a spray bottle.
A low-lint cloth to avoid contaminating the adhesive with dirt or lint particles. Paper coffee filters is a good alternative.
A utility knife with breakaway blades used for trimming the film.
A rubber squeegee We recommend that the rubber squeegee should be between 4” – 5” wide, and have a flexible blade.
Edging Tool can be a ruler, credit card, or wallpaper trimming guide.
Also needed is a ruler or tape measure some transparent tape and a razor blade.
Measure your window carefully before cutting. Unroll the window film on a clean, flat surface. Cut the film according to the glass measurements but add at least an inch to all four sides. The extra film will be trimmed later. Try to use at least one ofthe factory edges.
The film is attached onto a clear liner. Before proceeding you need to identify which side of the film has the clear liner.
This is done by attaching two 3” – 4” pieces of transparent tapeto the front and back surfaces of a corner of the film. About 1” of the tape is on the film, the rest is centered and hanging over the pointed corner. Press the two pieces of tape firmly together, then quickly pull them apart this will begin separating the clear liner from the sticky side of the film.
DO NOT remove the clear liner entirely. Leave the tape strips in place and continue to the next step in installing window film.
Spray the Application Solution onto the inside surface of the window generously. If the window becomes dry, re-wet it completely before installing window film. The wetter, the better.
Spray both sides of the film sheet with the Application Solution. This will help reduce film curl and static electricity.
HELPFUL HINT: Having a helper hold the film sheet by the edges while you spray will make it easier and quicker.
Now you can peel the two strips of tape apart and release the liner starting at one corner. As you pull away the liner, start spraying the Application Solution on the exposed adhesive side of the film. Continue like this until the clear liner is removed and the adhesive side is completely saturated. Try to keep the film from touching itself.
Using a sharp razor blade or utility knife, and the Edging Tool trim a 1/16” gap around the four edges of the film.
This gap is crucial so that the glass should be able expand due to changing temperatures. Also it allows you to completely squeeze out the water and air from under the film.
Make the film wet again and squeegee from the center to the right side and work downward.
Repeat this process for the left side. Press very firmly making sure that all the water is removed so that the adhesive can cure clearly. Squeeze out all air bubbles now. Any remaining small water bubbles should evaporate as the film cures.
If “fingers” appear along any edge, wrap your squeegee with a low-lint cloth and carefully push toward the edge of the film. Hold in place to absorb any excess water.
It takes a week to 10 days after installing the window film for the film to fully “cure”. Dry, sunny weather makes it faster; wet, cold weather makes it take longer.
The film might look hazy or cloudy at first however this effect will disappear with time and/or exposure to heat (i.e. the sun or a hair dryer).
Warning: Extra caution should be taken when installing window film when the bottom edge of the window is high up. Handling film on a ladder is at least twice as difficult as applying film to a large patio door by yourself. Consider hiring a professional for these jobs.
