Why Does Window Tint Bubble And Turn Purple?

February 24, 2023

Are you sick and tired of seeing those unsightly bubbles in your window tint? It can be annoying when your tint job looks like it’s crying tears of frustration. But no matter how much you imagine your car’s windows have a soul, the truth is that window tint bubbling results from something far simpler, like human error or another technical cause. Hence, if you are wondering why window tint bubbles and what solutions exist, you are in the right spot! In this blog post, we'll explore the various causes of window tint bubbling and offer solutions to help you keep your car windows tinted and pristine. Let’s dive in!


What Causes Window Tint to Bubble?


Bubbles in window tint are a common and annoying problem that can happen when you put it on your windows. But what causes this to happen? When window tint bubbles, it could be because of many different things, but the two most common reasons are bad installation and low-quality film.

Inadequate installation is often seen as the primary source of the bubbling issues. If the installer does not take their time or fails to understand how to install the tinting film properly, then uneven distribution may occur, which creates weak spots and air pockets between the window and the film that lead to bubbling. Air bubbles can also be caused by a tinting film that wasn't put on properly or was cut or squeezed imperfectly. Additionally, if excessive heat is used during installation, it can cause bubbles to appear within a few hours after application or over a longer period as the weeks pass.

Poor quality of window tinting film may also contribute to bubbling issues. Pre-cut tints, often found in kits, provide consumers with an inexpensive alternative to custom applications. Still, they are more prone to bubbles since they are mass-produced quickly without standard fixing procedures. These window films often have weak adhesives that fail to adhere securely to the glass, removing bubbles. providing weak points where air pockets and sustained stress are more likely to build up, resulting in bubbling.

The importance of using quality materials and proper installation techniques by an experienced installer cannot be understated when it comes to reducing instances of bubbling. To optimize your chances of success and get the best results out of your window tint, it is important to find an experienced installer who understands the importance of using good quality materials and has experience with correct installation procedures. That said, let's move on now towards looking at some of the different materials and compounds used in creating window tinting film.


Different Materials and Compounds


When it comes to different materials and compounds, there is some debate as to whether they are the culprit behind window tint bubbling. On the other hand, some window tinters point out that cheaper tints might be at fault because these tints use a lower-quality adhesive material. Lower-quality materials can crack over time due to heavy exposure to ultraviolet rays from the sun, leading to bubbling.

Some experts argue that it's not necessarily the material that causes bubbling but how well it has been applied. A poor installation job could result in air pockets forming underneath the tint film, leading to or contributing to bubbling.

Ultimately, both factors play a part in determining the degree of bubbling on window tints; however, evidence suggests that a higher-quality installation job is important to prevent or minimize bubbling. This is just a tiny piece of the puzzle to prevent window tint bubbles, though, as temperature and humidity should also be taken into consideration when assessing potential risks of bubbling since drastic changes in soap and water, either way, can affect the structural integrity of a tinting job over time.


Temperature and Humidity Shrinking


Temperature and humidity rarely play a role in why window tint may bubble; however, it can be a factor in some cases. When air temperatures rise, glass expands due to the normal thermal expansion of air molecules. This causes tension in the film and can cause it to pull away from its adhesion around the edges or bubble. In high humidity or warm conditions, moisture will form between the glass and the film, which can also cause bubbles.

In both cases, the best solution is to choose quality materials and window film rated for extreme climates. If you live in an area with extreme temperatures or humidity, you will be more likely to have window film bubbling. Cheaper films sometimes shrink faster when exposed to these climates because they are not built with high-quality materials and lack adequate sealant.

To prevent any bubbling due to extreme climate conditions, it is recommended that quality window film is used with superior adhesive backings and good seals at the edges of the window frame. It is also important to use professional installers with experience installing in climates like yours; this way, expertise and care can be taken to ensure your tint lasts for years without any issues. Taking these precautions can reduce the chances of your window tint bubbling due to temperature or humidity shrinking.

Quality of the Film and Sealant


Temperature and humidity can contribute heavily to window tint bubbling, but the quality of the film and sealant are also critical factors. Professionally installed window tints are usually made from high-quality film and adhesive sealant that won’t bubble up when the sun, temperature or humidity changes. However, not all installations are of the same standard. Some DIY kits come with a cheap film prone to bubbling and may not be backed by a warranty. A poorly installed tint may begin bubbling shortly after it’s applied, as it may not have been heat-shrunk properly or laid across body seams, making it easier for the material to lift. Furthermore, inferior products often don't contain UV inhibitors, which can cause the colour to fade over time.

When having tint professionally installed, ensure the chosen company uses quality equipment and offers a warranty on the work done. The installer should also be experienced at working on vehicles to ensure that each panel is cut precisely for a proper fit. If corners are cut during installation, such as using poor-quality film or attempting to install film on top of body seams, it could lead to damaged seals and bubbling down the road. Such issues can be avoided by investing in quality services and materials upfront—while they may cost more initially, they will save you costly repairs in the long run. You can prevent bubbles from tinting your window by paying attention to the temperature, humidity levels, and material quality.

We now focus on solutions that can help mitigate any issues with bubbling due to temperature variation and other causes.


Solutions to Prevent Bubbling


When seeking a solution for bubbling window tint, it's important to remember that quality and professional installation are the two key components in preventing the problem. In one sense, investing in a better quality film specifically designed to resist bubbling may be a good solution. While this will cost more upfront, finding a reliable film may be worth the payoff. Some film suppliers have even created special adhesives or sealants that work with the film to remove bubbles and ensure it remains uninterrupted on your windows.

On the other hand, if you choose professional installation from your car dealership or another reputable company, you can be sure that the work will be done correctly and that the results will be better. Professional installers of tint films often have a warranty that protects you against any bubbling issues during their service. Furthermore, their experience with tinting allows them to apply each sheet of film correctly on each window for maximum effectiveness.

Ultimately, whichever solution you choose should depend on what level of risk and cost you're willing to accept. Both options require an initial investment, but if you're looking for long-term assurance, professional installation may offer better returns on time and money saved. Because of this, it's important to compare both options and figure out the best way to stop bubbles from forming in windows. With this in mind, exploring professional installation solutions is often the best bet for bubble-free window tints.


  • The most common cause of window tint bubbling is a poor installation job caused by incorrect techniques or low-quality materials.
  • In some cases, the type of glass and chemical makeup of the window may also play a role in the bubbling of tinted windows.
  • Improper cleaning can contribute to window tint bubbling, as certain chemicals in solvent cleaners are incompatible with the plastic holding the film in place.


Frequently Asked Questions and Their Answers


What maintenance can be done to prevent window tints from bubbling?


When it comes to maintaining window tint to prevent bubbling, the best solution is to make sure you properly clean and protect the windows before installation. Before installing the tint, thoroughly wash the window with a glass cleaner and a soft cloth. Any dirt, dust, or oil on the window can attract heat and cause later bubbling. Additionally, you should use a quality primer on the glass surface and film before installation to ensure good adhesion and a more durable result. Finally, after installation, it is important to avoid using harsh chemicals when cleaning the windows, as this can adversely affect the film. Taking all these steps will help prevent the bubbling of your window tint.


What causes window tints to bubble?


Window tints can bubble due to several factors, including poor installation or the use of inferior or low-quality tinting material. Poor window tint installation is one of the most common causes of bubbling and can occur for various reasons. These may include:

Incorrect application process - Applying the film should be done in two procedures—first from the inside and then from the outside—to ensure sufficient film adhesion on both sides of the glass. Furthermore, vinyl must be allowed to settle on the glass before sliding tooled edges over them. Failure to adhere to these recommended steps may lead to bubbling.

• Overlap errors - If overlapping occurs along the edges where the window tint meets, air bubbles can form as the overlapped film won't adhere properly. Extra caution is needed when applying the film along the edges and corners to avoid this issue.

• Uneven surface temperature - If a large temperature difference exists between surfaces where window tint film is applied, it can cause an imbalance between heating up and cooling down that leads to bubbling. This scenario is more likely bubbles occur when installing film during hot climate days since cooler surface temperatures might create issues with adherence along glass borders, leading to bubbling.

• Improper cleaning – Windows must be perfectly cleaned by a window tint application to prevent air bubbles from occurring beneath them. Even more so, dirt on one side and not on the other will cause even greater problems with adhesion, leading to bubbling and/or fading of your tint in no time.


Are there any special techniques for installing window tint that can help prevent bubbling?


Yes, certain techniques can help prevent window tints from bubbling. Choosing a high-quality window film is essential, as some lower-quality films can be prone to bubbling up faster. It also helps to make sure the film is cut to fit the car window or piece being installed precisely - when it is slightly larger than the glass, it leaves gaps in the installation that could invite moisture to get in. Finally, be careful when applying the window tint; it's important to keep the adhesive side of the film dry and free of dust and dirt so that it sticks properly and creates an airtight seal on the window surface. With these steps in mind, you should be able to avoid having any problems with bubbling tinted car windows.
