The window must be thoroughly cleaned and degreased. This can be done simply with warm water and a drop of dish soap. A thorough cleaning prevents dirt and dust particles from getting between the window and the film. Remove any blemishes with a window scraper.

First, measure the window with the tape measure.

Roughly cut the film to size. We recommend cutting the window film 1 to 2 centimeters wider than your measured width. You can easily trim away any excess film.

First, thoroughly spray the window with a plant sprayer. This will allow the film to shift during application.

Peel off the backing (this can be paper or transparent film) from the window film. This is easily done by applying tape to both the window film and the backing.

Carefully peel the backing from the window film. Immediately spray the exposed window film with water. This prevents the static charge from attracting dust particles and getting between the film and the window.

Start in a corner and work your way out. Make sure the film is pressed tightly against the window. Applying window film is a simple but precise job. We therefore recommend two people.

Once the window film is applied to your liking, remove any excess water between the window and the film. Use the squeegee (to prevent scratching) to smooth the film from the center outward.

Now that the window film is in place, you can trim away any excess film with a utility knife, if applicable. After that, you're done and can enjoy your privacy, cool air, and immediately save on your energy costs.
