How to install transparent window film?

First, clean the glass surface, then generously spray water on both sides of the glass and the film. Then, peel off the backing paper and apply the film to the glass, removing any air bubbles with a squeegee.

What tools are needed to install transparent window film?

For example, a scraper to remove air bubbles, a craft knife for precise cutting, a ruler for exact measurements, and a clean cloth to wipe the surface (some of these tools must be prepared by you).

The transparent window film doesn't adhere well to the windows. Do you have any recommendations?

If the privacy window film doesn't adhere well to the window, be sure to carefully remove any dust or residue from the surface. Adding a little soapy water may make installation easier.

Why does the edge of window film curl? How do I deal with warped window film?

The cause is insufficient adhesion or improper installation. Reapply the film to remove any air bubbles. Or use a hair dryer to heat the curled area to ensure it adheres firmly.

Why isn't the film sticking properly and is it falling off?

The transparent protective film hasn't been removed. Remove it for proper adhesion. If you removed the protective side, you may have applied the wrong side. Apply the smooth side to the window.
