Installing window security film can be a great way to enhance the safety and protection of your home or business. Still, the process is complicated and requires a high degree of precision. Before deciding who to choose to install your film, it can be very helpful to understand how the process works.


With an industry as big as window film, there’s no shortage of companies or technology. In the end, there’s only one way to go about performing window security film installation correctly. Here’s your step-by-step breakdown of the process:

Step 1: Preparation

The first step in any window film installation process is to thoroughly clean and prepare the windows. It’s vital to remove any trace of dirt and dust from the surface of the glass, as even the most minor debris can cause bubbles and poor adhesion. 


The installer will also remove any window accessories like stickers, adhesives, or other items as they can interfere with the adhesive. Once the windows are spotless and dry, they are ready for the next step.

Step 2: Measuring and Cutting

Before the security film can be applied to the windows, the pieces will need to be cut to size. This involves taking careful measurements of each window, which can be a complicated process. The measurements must be precise in order to get an effective adhesion.


Once they’ve taken and recorded the measurements of your windows, they’ll determine the size and shape of the film for each window. Cutting the film to the proper size and shape is an equally delicate process requiring a heavy-duty utility blade or a specialized tool for cutting window film.

Step 3: Applying the Film

Before applying each piece to its corresponding window, a soapy water solution will need to be sprayed across the glass. This will make it easier to manipulate and position the film as needed until it’s perfectly in place.


Once the film has been placed, it will need to be smoothed out with a squeegee-like tool to remove any air bubbles or wrinkles, no matter how minor. This is important not just for the visual appearance of the window, but for the effectiveness of the film’s function. 


If the process sounds complicated and difficult, that’s because it is. A flawless application requires a lot of skill and prior experience to execute properly.

Step 4: Trimming and Finishing

Once the security film has been applied, positioned, and smoothed over, it’s time to trim away any excess film that doesn’t fit perfectly with the window. The trimming is done with the same utility blade or specialized tool the installer used during the cutting process.


After all the excess film has been trimmed away, the edges of the film will need to be sealed using a specialized sealant. This is to make up for any tiny flaws in the installation while protecting against the wear and tear that should be expected on any window. This helps to ensure that the film’s edges stay attached long-term by preventing damage to the edges and keeping debris and water out. The result is a stronger seal and a clean, professional look.

Step 5: Drying and Curing

Once the security window film has been cut, applied, trimmed, and sealed, the installation becomes a waiting game. This allows the film to dry and cure properly. The extra time causes the film to bond fully with the window surface, ensuring the longevity of the installation.


This part of the window security film installation process can vary from case to case. Fully drying and curing can take the film anywhere from a few days to a week, depending on factors like the weather and humidity of the area.
