After cleaning, inspect the window for any remaining dirt or imperfections. Even small particles can cause bubbles under the film. Make sure the window is completely dry before moving on to the next step.

Measure and Cut the Film

Measure the dimensions of your window carefully. Cut the film slightly larger than the window to allow for adjustments. Use a utility knife to make precise cuts.

Apply the Film

Peel the backing off the window film. Start applying the film from the top of the window, working your way down. Use the squeegee to press the film against the glass, removing any air bubbles as you go.

Smooth Out the Film

Once the film is in place, use the squeegee to smooth out any remaining bubbles. Work from the center of the film towards the edges. This will help ensure a smooth, professional finish.
