Will small bubbles in window film disappear on their own?

[StJaxson]

Yes, most small bubbles will disappear after sun exposure. Below is relevant information about small bubbles in window film:1. Low-quality film: Inferior car window film will appear foggy when viewed from inside out. Rough bonding between film layers may cause bubbles or wave patterns.2. Improper installation: The most common cause is insufficient technician skill during installation. If the glass surface isn't properly cleaned and dust remains, as the film's adhesive strength increases, pressure forms around sand particles or dust, resulting in bubbling. Adhesive failure may also cause bubbles.

As a car owner who has undergone multiple window tinting procedures, I've noticed that the small, rice-sized bubbles that appear right after installation are mostly caused by trapped moisture during the application. These vapor bubbles usually disappear on their own after being exposed to sunlight for two or three days, and I've seen many cases resolved this way. However, bubbles larger than half a centimeter in diameter should raise concern, as they might indicate dust contamination during installation or improper film adhesion - these bubbles have virtually zero chance of disappearing naturally. I recommend observing the tint for about a week after installation. If the bubbles don't shrink but instead grow larger, you should promptly contact the installer. Particularly for bubbles at the edges, prolonged existence may lead to dust accumulation affecting aesthetics. When I encountered larger bubbles myself, I tried using a squeegee card to push them out, but the results were mediocre at best, and excessive pressure could actually damage the film surface.

I've been in the window tinting industry for seven years and often get asked whether bubbles will disappear. Here's the conclusion: small water droplet-like bubbles can usually dissipate on their own, while air bubbles generally won't. For water vapor bubbles left during installation that are under 2mm in diameter, sunlight exposure can accelerate evaporation, typically flattening them within two weeks. However, if the bubble edges have turned white or show obvious dry lines, it means the bubble has existed for over half a month and has already set. I've seen many car owners try to puncture bubbles with needles, only to damage the film instead. Professional shops actually offer warranties - if you notice stubborn bubbles, it's recommended to return within three days for treatment. Also worth noting: bubbles disappear slower with winter installations, requiring at least a three-week observation period.

I recently had my car window tint replaced and noticed clusters of pinhead-sized bubbles on the third day. The tint shop explained this is normal as moisture evaporation takes time. After ten days of intense sun exposure, most bubbles indeed disappeared. However, a few bubbles along the edges grew larger and had to be fixed last week when I returned to the shop - they used a heat gun to resolve it. Based on my experience, bubbles can self-disappear only if they meet three conditions: being moisture-type rather than air-type, smaller than a sesame seed, and not located near folded edges. If rainbow patterns appear on bubble surfaces, it indicates dust contamination which requires re-tinting. Now during every car wash, I'm extra careful not to direct high-pressure water jets at window gaps.
