How Is Car Window Tint Applied?

Window tint arrives rolled up carefully on a cardboard tube before it’s installed on a car window. If you’ve never observed this process before, it’s worth a look.

While window tint can be applied by anyone, using a professional installer is a distinct advantage; if you’re in North Carolina, for example, it may be worth your time to search for Apex car window tinting that can be installed by a professional. That roll of window tint can be an investment that lasts for years if it’s installed correctly.


Here’s how car window tint is applied.

Use the right tools

A professional window tint installer uses the correct tools to get the job done. The first tool needed is a cutting blade. Many installers use a retractable knife with snap-off blades to make sure the tint receives a clean cut every time.


Getting the film off the rolled-up tube and applied to the glass of the car or working space is a crucial first step. Using a dull blade or holding the cutting knife at the wrong angle will create kinks in the end product. With the front windows, it’s especially important to use a fresh blade since those windows have a curve.


Some window tint installers will take their newly cut piece of tint and apply it directly to the window on the car. Others will stick the tint on a flat glass using a combination of water and one other ingredient.


A common spray bottle is used to apply these two ingredients. The second ingredient is a slip solution designed to make the tint easier to work with. Believe it or not, baby shampoo is often used for this step.


If the tint is put on a flat glass to cut before installing it on the car, it will be maintained in a wet condition. If not, the film could be scuffed.

Use a squeegee to get the final steps accomplished

After cutting and fitting the tint, the next step is to remove the liner and use a squeegee. This gets the tint placed in its permanent position.


The window tint is in two parts. One is the side that faces the inside of the car, and the other side is a clear liner that needs to be removed for the final installation.


The inside of the film is coated with an adhesive that will keep the tint in place after installation. When the liner is removed, the adhesive is exposed. During this step, the installer will spray it with copious amounts of water from the spray bottle. The film is applied to the inside of the vehicle without letting any contaminants get between the tint and the window.


Using the squeegee on the wet film is the last step for the majority of vehicle window tint installations. If the tint is applied to a rear window that has curves in it, the tint will need to be shaped to the proportions of the glass. A high-heat air blower is used to shape the film. Using the blower requires some extra professionalism to get this step done right.


On the front windows and passenger windows, a squeegee is all you need because the tint is already perfectly formed to the window. The bubbles are painstakingly moved from underneath the tint using that squeegee. This final step is repeated until there are no bubbles or other impurities between the vehicle glass and the window tint.


The steps above might sound simple. But in many cases, this process is easier explained than done.
