Window Film Installation Instructions (With Images & Video)

* Because the film may crease if it bends, having two people work with the material on larger windows is preferable.

* When trimming excess material from the window, use a rigid card as a guide and to hold the material in place at the edge of the window to ensure the most accurate cut.

*Slightly round corners where the film meets corners to avoid lifting.

*Do not install in extreme weather conditions.

Long Term Care:

Maintenance: After the film has dried fully (1-3 days), you may wash the surface of the film with a lint free cloth and soapy water. Do not use chemical or abrasive cleaners on the film. Natural cleaners such as “Lavender Spray” by METHOD may be used sparingly if film is soiled with dirt or grease.

NEVER APPLY FILM NEAR OPEN FLAME OR HEAT SOURCES (i.e next to burners or heating elements). Standard household radiant heating devices will not harm the film if they are installed to code and proper distances from windows.

  1. Lay the roll of film pattern side up to allow the film to relax and flatten out. Weighting the corners with a book or magazine will quicken the process.
  2. Remove any caulk, paint or glue debris that may be stuck to the window. Clean the glass surface with a household window cleaner and dry thoroughly.
  3. If your film has not been custom pre-cut with score lines, measure your windows and mark the dimensions on the face of the film with a pencil or marker. Always add 1+ inch on every side when doing this so you have excess film to trim away from the window after positioning.
  4. Peeling the film off of the backer: When you’ve cut your film down to size, you may need to use two pieces of tape and adhere to the rear and front of one corner of the film to remove the film from the backer. Continue to lift the film from the backer until it is completely free of the liner paper. (Large pieces will require two people to manage the window film.)
  5. Spray the window generously with a spray bottle filled with water and 1-2 drops dishwashing liquid (Joy, Dawn, etc.). Spray the back of the film to activate the adhesive. Both window and film should be fully misted without excessive water dripping. Without enough water there will be unwanted air bubbles.
  6. Starting at a top corner of the window, press down the top edge of the film with your fingers, then continue to lay the film down with your hands, following with your squeegee to ensure full film to window contact. (Hint: Spraying the front of the film lightly will make the squeegee move smoother and avoid scratching). With your squeegee make sweeping movements outward from the top down and center outward to remove excess water and bubbles. It might also be useful to squeegee in very short and deliberate strokes to “chase” the bubbles out to the edges. Be persistent, the water will find its way out if gently coaxed!
  7. Using your squeegee, work the film into the edges as tightly as possible then trim excess material away with a VERY sharp knife with a new blade installed.
  8. If bubbles persist, use a fine needle to pierce the bubble and force the air out through the pierced hole.
  9. For several days the film will cure and adhere to the glass fully. As the adhesive takes hold patches of cloudiness may develop, but these will disappear when drying is complete. Above or below average temperatures may extend drying time.

REMOVAL AND REUSE: The film may be removed, stored, and reused at any time. Take care to remove slowly and gently. Wipe both sides with a wet lint-free rag to remove any debris before storing. Once dry, carefully roll and tuck away. The same application instructions apply for secondary installations.
