How to Apply a Window Film {aka How to Not Flash Your Neighbors}

When we were remodeling our master bathroom, I wanted to do a window treatment that would allow us to take advantage of the natural light while not giving the neighbors a show. We decided to try a privacy film on the window, which gives the glass a frosted appearance so light comes in but creepy peepers stay out.

Surprisingly (or at least I was surprised), it worked great! My husband and I each took turns walking behind our house at night to see if anything was visible through the window. Other than being able to tell that someone was in the room (in the form of a fuzzy silhouette), you couldn’t see a thing!

While I would recommend having a second set of hands to help with the application, the whole process is really quite easy. We used the Gila Privacy Control Window Film in a Simulated Etched Glass finish, but there are multiple brands and finishes to choose from.

Start by cleaning the window thoroughly, making sure to get into the corners.

Measure the size of your window and cut the film, adding an extra inch to each side. If your window is like ours, you’ll need to measure the top and bottom and cut two separate pieces of film.

Using two small pieces of tape (one on each side of film), identify the clear liner. Your window film kit should come with a spray solution: use it to generously wet the window. Get someone to hold the film and, as you pull off the clear liner, spray the newly exposed side of the film. Apply the wet film, adhesive side down, to the window.

Smooth the film with your hands, and spray the side of the film facing you with the solution. Squeegee the center of the film from top to bottom. Go back to the top of the window and squeegee from the center to the right, working downward. Do the entire right side of the window and then repeat on the left side.

Use the edging tool and a utility knife to press down the edges and trim off the excess film on all four sides. 

Spray the film again with the solution and squeegee dry, again working from the top to the right and downward. Repeat on the left side. This is the point that you want to make sure you’re getting out any air bubbles behind the film. Also, use the edging tool to really push the film down in the corners. 

If your window is split (like ours), repeat the entire process on the other half.

Aaaannnnndd. . . you’re done!
