Frequently Asked Questions
What tools will I need for installation?
You will need something to clean the glass, a razor knife (included with your film), masking tape, a squeegee, a credit card or hard card (included), a soap and water solution (see <a href="https://decorativefilm.com/adhesive-window-film-installation-instructions"> Instructions</a> for details), and a 32-oz. spray bottle (or adjust ratio for other sizes). <a href="https://decorativefilm.com/accessories-installation-tools"> Need an Installation Kit?</a>

Can film be installed on the outside of a window?
With the exception of films specifically labeled and made for exterior application, always install film on the interior of a window. Film applied to the exterior will easily fail due to exposure to the elements.
How do I work with film that is curled?
Because the film is rolled for shipping, it may be slightly curled prior to application. For best results, unbox, unroll and let all films come to room temperature on a clean, flat surface for 24 hours before installation. This will allow the film to relax. If the edges of the film continue to curl after installation, wrap your squeegee in a few layers of paper towel and push the edges of the film down, moving from just inside the edge to just outside. If the edges continue to curl, turn a hair dryer to the warm (not hot) setting, hold about 8-12 inches away from the film to evaporate any excess moisture, and repeat the squeegee process.
Can film be installed on plexiglass, polycarbonate or acrylic?
Yes, most films can be installed on plexiglass, polycarbonate or acrylic surfaces. But unlike glass, some of these materials expand and contract with temperature changes and emit gas—which may cause air bubbles to form between the film and the surface. Use more soap in your wetting solution when installing on these surfaces.
Can film be installed on textured glass?
No. Film will only correctly adhere to flat, smooth surfaces.
Can film be installed on double-pane windows?
Yes. With the exception of some blackout films, all our films are safe for installation on double- or triple-pane windows.
How do I clean the film after installation?
Use any non-ammonia widow cleaner and a microfiber cloth. We recommend SimGlass® Window Film Cleaner, which is available for purchase on our website. Make sure any cleaning professionals are notified that you have films on your windows.
How do I remove film?
All films can be easily removed without any damage to the glass. Begin by peeling the film away from one corner of the glass and pulling down until the entire panel is removed. If any adhesive remains, it can be easily removed with window cleaner, soapy water or a single-edge razor blade.
How do I place seams?
Before you do any actual cutting, you should consider where to place the seam on the window. You will usually have options when deciding: do you want it vertical or horizontal? Higher or lower? It may depend on the width of the roll you are working with, but generally you’ll want to place it where it is least noticeable. If you have tall windows, placing it at the top will make it harder to see. If it is darker at the bottom or people tend to look toward the top more often, then placing it at the bottom will be the best method.
How do I cut the seam?
The second factor to consider when doing this technique properly is the cutting. Some customers try to cut the two pieces as true as possible with a straight-edge, then line them up and install. Or, they make sure to use the factory edges of the film when ”butting” the two ends together. This can work well, but most times it is difficult to cut the film perfectly straight, or using the factory edges creates too much waste. The best method to splicing is to overlap the two pieces about 1/2” where they meet. Install the entirety of the pieces, then use a sharp blade to cut down the center of the overlap. Since the pieces are installed and adhere firm on the window, they shouldn’t move or peel while you are slicing. Remove the sliced strips of film and you are left with a tight seam.
