How to Completely Remove Bubbles and Stick Firmly
The window film is static cling which can be easily removed for adjustment.
1. Ensure the window is thoroughly cleaned without any dust before proceeding with the installation.
2. If you encounter stubborn bubbles. gently lift the film's corner or peel off the whole piece. spray plenty of water once more. and then re-position the film and firmly slide a squeegee or a hard card across the surface to eliminate all air bubbles.
