Frosting adds a touch of privacy to a window without sacrificing light. Whether your windows are made of glass or Plexiglas (transparent plastic glass), you can create a frosted look with the application of decorative window film. Decorative window film clings to the Plexiglas, giving it a frosted appearance in minutes. Better still, the film is only temporary, which means that you can remove it whenever you want.

  1. Measure the size of the piece of plastic glass you want to frost using a tape measure. Flip the sheet of film face down onto your work surface and mark the same measurements on the back of the film with a pencil.

  2. Cut the frosted film to size with a sharp pair of scissors or use a utility knife. Make sure that if you use a utility knife that you place a piece of cardboard or thin sheet of wood in under the frosted film to prevent damage to your work surface.

  3. Clean the Plexiglas with a microfiber cloth and window cleaner. Fill a spray bottle with room temperature water and add a squirt of dish soap. Spray the Plexiglas lightly with the soapy water after cleaning.

  4. Remove the backing from the frosted film. Press the sticky side of the frosted film to the soapy Plexiglas. The soap will prevent the film from sticking right away, allowing you time to make any necessary adjustments.

  5. Spray the frosted film with soapy water once it is in place. Starting in the center of the Plexiglas, use a rubber squeegee out an air bubbles that exist between the frosted film and the Plexiglas.

Tip

Rubber squeegees are available online and in hardware stores. Some film kits include a squeegee.

Warning

It is a good idea to wash your hands prior to applying the frosted film to the Plexiglas. Oils on your hands can leach onto the film and prevent it from sticking to the Plexiglas.
