How is 3M Window Film applied?
With the exception of our Do-It-Yourself Window Films available at Home Depot, all 3M Window Films are designed to be professionally installed by skilled, authorized 3M Dealers. Almost all are also designed to be applied to the inside of your glass.
The first step is to prepare the window area for the application; placing drop cloths on the floor protecting and/or moving furniture where necessary.
Next, the window glass is cleaned using simple cleaning solutions (often water and ammonia) and razor blade scrapers. Then the film is sprayed with a slip solution (detergent and water) for proper positioning, and applied to the window glass. Using a professional grade squeegee and following proper techniques, the application is completed by removing excess water, trimming the edges, and a final squeegee technique to dry the edges.
