Clean the Window Frame: Use a mixture of mild soap and water to clean the window trim. Wipe the entire perimeter of the trim with a soft rag or sponge. Be sure to allow enough time for the trim to fully dry before moving on to the next step of applying the 2-sided tape.

Apply 2-Sided Tape: Install the 2-sided tape around the entire perimeter of the window trim. Be sure to press firmly along the entire length of the tape. Do not remove the protective cover until you measure the window and cut the film to size per the step below.

Measure & Cut: Measure the overall height and width of the window. Add 1” or more to each dimension and carefully cut the film to suit. As always, “measure twice cut once”.

Apply the Film: Peel the protective cover off the 2-sided tape. Align the film with the upper left-hand corner of the tape, overlapping the window by about half an inch. Continue to adhere the film to the tape along the top edge, while being careful to hold the loose end away from the window at the bottom.

Remove the Wrinkles: With the film attached to the entire perimeter you can stretch it as needed to remove any large wrinkles. When satisfied with the general flatness of the film, run your thumb around the entire perimeter of the film to secure it to the tape.

Shrink the Film: Now you can use a blow dryer to shrink the film and remove any minor wrinkles. Keep the blow dryer moving to avoid overheating the film in any one area.

Trim the Edges: Use a pair of sharp scissors or an Exacto-Knife to trim the overlapping film. Be careful to not cut into the window frame itself.
