Simply find something to squeeze out these bubbles. Of course, this method only works for bubbles located at the edges of the film, as those in the middle cannot be addressed this way. The same approach applies to car window tinting. You can use a bank card or a bus card to squeeze out these bubbles, and the operation is quite simple. If the bubbles at the edges of the film have been squeezed out, you can use a small needle to puncture the bubbles in the middle. This method may seem a bit aggressive.

Last time I applied window film myself, I also encountered bubble issues. I remember the most crucial step is to use a plastic squeegee or an old credit card to slowly push and press from the center of the bubble outward. Don’t press too hard, or the film might tear. If the bubble refuses to budge, gently poke a tiny hole with a sewing needle to let the air escape, then flatten it. It’s normal to have tiny bubbles in the first few days after application—that’s just moisture evaporating, and they might disappear after a while. However, if there are too many bubbles or they keep growing, it means the surface wasn’t cleaned properly or dust got trapped during installation. In that case, it’s best to peel it off and reapply. Before installation, make sure to spray the glass with installation fluid and wipe it until it’s spotless, using a blade to remove any dirt to avoid future problems.

Here's a little trick for dealing with window film bubbles: Within the first few minutes after installation, when the bubbles are still small, immediately use a soft squeegee to smooth them out. I always spray extra installation solution during application to allow the film to slide and adjust, reducing bubble formation. If the bubbles remain after the film has dried, try spraying water or installation solution around the bubble to moisten the area before pressing for better results. Thorough glass cleaning before installation is crucial—wipe the glass multiple times with glass cleaner to ensure it's free of dust and grease. Bubbles aren't just unsightly; they can also affect the film's adhesion, potentially leading to more bubbles or even cracking over time, so it's important to address them promptly.

After applying the film to my car, there were also small bubbles. I wasn't in a hurry, so I used an old bank card from home to slowly press down the edges of the bubbles. Pushing a few times made the small bubbles disappear, while for larger bubbles, I gently poked a small hole to let the air out. Remember to move slowly to avoid scratching the film. After applying the film, moisture can evaporate and cause bubbles, so wait a day to see if they disappear on their own.

The right tools are crucial for dealing with window tint bubbles. A specialized tint squeegee with a soft edge is ideal as it minimizes film damage; in a pinch, a plastic ruler or credit card can also work. When working on bubbles, press from the center outward toward the edges—using a heat gun to gently warm and soften the film before pressing can enhance results. Bubbles often stem from dust or uneven application fluid, so always clean the glass thoroughly and scrape it smooth with a squeegee before installation. Untreated bubbles may compromise the tint's effectiveness and shorten its lifespan, so address them promptly—don’t skip this step.
