Apply Top Edge of Masking Film

What happens here

Start the masking process by attaching the masking film and tape from the dispenser to the top of the window frame. Position the tape about 0.25 inches (6 mm) from the edge of the window glass. Draw the dispenser smoothly across the entire top width of the window, ensuring the tape adheres firmly to the frame. When reaching the opposite side, maintain the 0.25-inch (6 mm) gap from the edge and then snap or tear the film and tape loose from the dispenser.

Goal: Secure the top edge of the masking film to the window frame.
