You will need an atomizer filled with distilled water and a clean rubber squeegee. Clean the window with a high quality window cleaner. Use a microfiber towel so as not to leave any lint or dust behind. Spray the glass with water and place the window film in position. Begin to squeeze most of the water from beneath it. Trim the film with a fresh razor. Squeeze the balance of the water from beneath and you are all set. Remove any air bubbles present for a perfect installation. Good luck. Practice makes perfect!
Hi, the best you can do is to hire some experts. Believe me. I recommend to have a look at window-films-solaris.co.uk and their mirrors www.window-films-solaris.co.uk/mirror. You see, this company is not just an online glass film shop, but also a professional window film installer. My cousin ordered window films last year through that company and says it worked pretty well for him. Simply give them a try! All the best
