How to Remove Air Bubbles from Car Film?

 believe that many film store owners have encountered the problem of blistering after the car film, right? Today, YINK will guide you on how to quickly and effectively remove air bubbles from vinyl wraps.

Air bubbles on vinyl wraps are a common issue. The causes of bubbles may vary, such as not fully removing air during installation, uneven or dirty surfaces, inappropriate temperature (too high or too low), remaining moisture or water, improper handling, or even issues with the wrap itself. All these factors can contribute to the formation of bubbles.

Once bubbles form, they not only affect the vehicle’s appearance but can also shorten the lifespan and functionality of the wrap, and in some cases, pose a safety risk. Therefore, depending on the type and condition of the bubbles, we need to adopt different methods to resolve the issue.

1. Waiting for Small Bubbles to Self-Heal

Firstly, not all bubbles need immediate action. For example, tiny bubbles that are hard to spot with the naked eye are often caused by air not being fully removed during installation, or air trapped between the film and the surface. These types of bubbles are a natural occurrence and will gradually disappear over time, especially in warmer weather.

So, if these tiny bubbles don’t affect the film’s function or appearance, you can simply wait, and they will likely disappear within a few days to weeks.

2. Using a Squeegee: Suitable for Small Bubbles and Minor Adjustments

A squeegee is a popular tool for removing air bubbles, especially for those that have begun to release air naturally or those that require only minor adjustments.

Method: Lightly push the squeegee from the edge of the bubble toward the center to help expel air. Be gentle to avoid excessive pressure that could damage the surface of the wrap. You can adjust the angle of the squeegee several times to ensure the bubble is completely removed and the film stays smooth.

Note: Make sure the edges of the squeegee are free from scratches or dirt to avoid leaving marks on the film. Be gentle when using it to avoid scratching or warping the wrap.

3. Using Heat Tools: Suitable for Small Bubbles and Temperature-Sensitive Bubbles

If the bubbles are small and difficult to remove, you can try using heat tools such as a heat gun or blow dryer. Heat softens the vinyl, allowing the air to escape more easily.

Method: Set the heat gun or blow dryer to a low temperature and keep a distance of about 15-20 cm. Evenly heat the surface of the film. After heating for a few minutes, gently use the squeegee to push the air out from the center of the bubble and flatten the film.

Note: Avoid overheating the film, and never hold the heat gun too close to the film for too long, as this may cause the wrap to deform or get damaged. Move the tool to avoid heat concentration in one spot.

4. Pin Pricking: Suitable for Larger Bubbles

For larger bubbles, waiting or heating alone may not be enough to remove them. In this case, you can use the pin pricking method with a professional air release pen or a household needle to puncture the bubble and release the air naturally.

Method: First, gently prick the center of the bubble with a needle, ensuring the puncture point is clean and precise. Then, use the squeegee to gently press around the bubble to expel the air and smooth the film surface.

Note: Keep the tools clean to avoid scratching the surface of the wrap. Apply light pressure to avoid damaging the film or leaving marks. The pin pricking method is suitable for larger bubbles; small bubbles are still best left to dissipate naturally.

Of course, dear store owner, while air bubbles are a common problem with vinyl film installations, they can be greatly reduced with a few preventative measures:

Clean the Surface: Before installation, ensure the windows or surfaces are thoroughly cleaned to remove dust, grease, and debris. Even tiny dust particles can cause bubbles.

Control Temperature and Humidity: Avoid installing the wrap in extremely cold or hot conditions. The optimal temperature for installation is between 20-25°C, which ensures the adhesive works best.

Even Pressure: During installation, use professional tools like a squeegee or air release pen to apply even pressure, helping to expel air. Avoid pulling too hard or working too quickly.

Avoid Excessive Moisture: If you’re using water to assist with installation, make sure all moisture is fully removed to prevent any leftover water vapor between the film and the surface.

By following these tips, you can effectively prevent bubbles from forming and ensure the durability and appearance of the wrap.

With the development of modern production technology, many shop owners choose to use machines for film cutting operations, which greatly improves work efficiency. However, for irregular-shaped windows, machine-cut films may be difficult to fit completely, increasing the risk of bubble formation. In order to ensure the fit and reduce the appearance of bubbles, we recommend combining PPF cutting software for precise cutting. This type of professional cutting software can adapt to special surfaces and better achieve precise fitting.
