A precise measurement ensures minimal waste and a neat final appearance. Remember the old saying, “Measure twice, cut once.”

2.3 Applying the Window Films

Now comes the main event: sticking the film to your windows. While it might sound nerve-wracking, a calm and methodical approach can make the process stress-free.

Spray the Glass: Generously spritz the window with your application solution so the film can slide around if needed.
Peel the Backing: Carefully remove the backing from the film. As you peel, mist the adhesive side with the application solution to prevent it from sticking to itself.
Position the Film: Align one edge of the film to the top edge of the window. Gently let it flow downward, ensuring it’s aligned properly.
Smooth It Out: Use a squeegee or soft applicator to push out the fluid and any trapped air bubbles, working from the center outwards.
Trim Excess: After the film is positioned, trim away any leftover edges using a sharp utility knife.

Keep the film and glass surface wet with the solution as you work. This lubrication helps you reposition the film if you make a slight mistake. Once you’re satisfied with the alignment, apply steady, even pressure to remove as much moisture as possible from between the film and the glass.

2.4 Post-Installation Inspection

Immediately after the film is in place, you might notice small bubbles or a hazy appearance. Don’t panic—this is often just residual moisture that will evaporate over the next few days.

Bubbles: Use your squeegee to gently guide trapped air or moisture toward the edges if they’re noticeable.
Edges: Check for proper adhesion. If corners or edges start peeling, press them back down firmly with a bit of extra solution.
Drying Time: Depending on the film thickness and weather conditions, it may take up to a couple of weeks for the film to fully cure and any haze to disappear.
