  1. Pre-cut film to 1/2" larger than area to be covered*

  2. If you have not done so already, mix soap spray as described above

  3. Spray surface of glass opening with soapy mix and clean with razor scraper (see our glass preparation video for more details)

  4. Spray again and squeegee the glass, then wipe perimeter and frame with paper towel (fold edges in-away from glass-to reduce lint)

  5. Repeat steps 3 and 4 until you are satisfied that the window is very clean

  6. (It is best that you have a helper for this step) Lightly spray both sides of the film with mix. Spray glass surface thoroughly. Peel liner from film and spray sticky back side of the window film AS you expose it.

  7. If your windows are square and the film is cut straight, you may try to position the film in the upper left-hand corner of the window. If not, overlap all edges of the glass with the film.

  8. Spray surface of the film and gently squeegee water from centre of work and push out to edges of the film

  9. Trim excess film, using straightedge as a guide

  10. Cover the 5-way tool or stiff plastic with paper towel and continue to push water to the outer edges of the film.

  11. Continue pushing out water to the outer edges until you are satisfied that you cannot remove any more water

*Decorative Window Film Installation:

Before cutting patterned decorative window films, ensure that you are cutting the film in the same direction for all windows, otherwise your patterns will not line up properly. For wider windows, some films may be cut length-wise, provided the width of the window film you ordered is sufficient to cover the length of the window. For example, if you purchase a 48" window film, but have a window that is 53" wide, you may be able to fit the film by turning it length to width, provided your window length does not exceed 47.5" ( Remember an additional 1/2' bias is required for both length and width.) PLEASE NOTE: You will not be able to do this with patterned decorative window films as the pattern will not line up!
