  • Step 1 : Wash the glass panels and frame

    Give the glass a good cleaning with your favorite glass cleaner and window squeegee. Make sure to remove any paint splatters or anything else that's hardened on the glass. Also wash the frame around the glass so the entire surface is dirt and grease-free. Let the surfaces dry thoroughly.

  • Step 2 : Measure

    Use a measuring tape to find the length and width of the glass surface to cover with the decorative film. Do this on the inside of the room, not outside. Transfer the measurements with a steel ruler and pencil on the backing paper of the decorative film.

  • Step 3 : Make the cut

    Cut and trim the film to size with a pair of scissors or a craft or utility knife. For a clean precise cut, hold the knife in place with a steel ruler or any other straight edge.

  • Step 4 : Wash your hands

    Wash and dry your hands. It's important to prevent dirt and oil from your hands from getting between the film and the glass when you apply it.

  • Step 5 : Apply the film

    Fill the spray bottle with water and a few drops of liquid soap and use it to mist the glass completely. This wetting makes it easy to position the film. Peel off and remove the film from its backing paper and position it on the glass. Use the side of your hand to smooth out large air bubbles ones. Have a rag handy to wipe up any excess water.

  • Step 6 : Adjusting the film on the glass

    Adjusting the film on the glass

    Mist the film with the soap and water in the spray bottle and then use the side of your hand and the plastic squeegee to remove any air bubbles as you smooth it in place.

    Sometimes an edge of the film begins to roll up and will not lie flat. If that happens, use a hair dryer set on a low heat setting to heat the film and make it pliable. Turn off the heat and hold it in place for about a minute or until the film cools to room temperature.

    Continue in the same way until all the decorative film is installed on the glass. For large panes of glass it's helpful to have a helper working with you.
