DIY Window Security Film Installation Instructions

A window security film is usually a heavy plastic that can be applied to your windows to make them shatterproof upon impact. This is important because it can prevent potential burglars from breaking through the window to gain easy entry into your home. Once you purchase the window security film of your choice, installation is a simple task that you can do on your own. 

To help you, here is the procedure you should follow:

Step 1: Remove the Grill

If your window has a single solid glass piece, removing the grill should be your first step. This will ensure that you have an easy time to proceed to the steps ahead. A faux divider should help you do remove the grill carefully.

Step 2: Take Window Measurements

After removing the grills, your next step is to take measurements of the window, including both the length and the width. Reduce the length by at least a centimetre or so before transferring the measurements to the window film with a pen. The one centimetre length is very important because it will leave a space at the film's edges to allow water to escape later on in your installation.

After drawing the measurements on the film, cut it out along the drawn lines with a knife and test to see whether it fits your window. If it's still big, adjust accordingly.

Step 3: Clean Your Window Thoroughly

Using water and a cleaning detergent, give your window a thorough scrubbing. For stubborn dirt and other debris, use a razor blade to remove the dirt by scrapping it away. You want to clean your windows thoroughly because any stains or dirt that remains on the glass pane will show up through your film unless you remove it and reinstall it.

Step 4: Spray the Window with Soapy Water

After cleaning the window, spray it thoroughly with some soapy water to enable you to slide the film into position.

Step 5: Pull Off the Window Film Backing and Position the Film to Your Window

Once you have sprayed the window with the soapy water, pull off the backing from the window security film and place the sticky side of the film onto your window. Hold the film at the middle and space it out on the window to fit well.

Step 6: Push Out Air Bubbles

Using a squeegee or credit card, push out the air bubbles from the middle outwards. You can then wipe the excess liquid with a clean cloth or paper towel.

When carrying out this exercise, wait until there's no direct/hot sun, such as in the evenings so that the heat doesn't interfere with the curing of the film.
