Is it normal to have small bubbles on a newly applied car film?
2 Answers
Whether small bubbles on a newly applied car film are normal depends on the specific situation. If they are air bubbles, they will not cause any issues and will disappear within about a week. However, if dirt was trapped during the application process, this is not normal, and the bubbles will not disappear on their own. In such cases, you should return to the installation shop for treatment. Precautions for applying a new car film: Before applying the film, check whether the window glass is installed correctly and the overall integrity of the car glass to ensure the subsequent film application process proceeds smoothly. Before applying the film, cover necessary areas inside the car to prevent liquid from seeping in. Clean the inner and outer surfaces of the window glass before applying the film (focusing on the interior side and the glass sealant area). This is mainly to avoid any dirt or foreign objects between the heat-insulating film and the glass, ensuring proper adhesion. Do not roll down the windows for 3 days after applying the film. Avoid washing the car during this period to prevent the film from peeling off. Do not clean the heat-insulating film or turn on the defroster switch for a week after application. Avoid using solutions containing alcohol or ammonia to clean the film surface.
Small bubbles after car window tinting require case-by-case analysis. Pinhead-sized water bubbles within the first few days aren't a major issue - these are typically residual moisture from installation that will disappear after parking in sunlight for a couple days. However, bubbles larger than a grain of rice or containing dust particles indicate poor installation, possibly due to unclean environment or unskilled technique. I recommend monitoring closely during the first week - if bubbles expand or persist beyond two weeks, return to the shop for rework. Note: many new car owners attempt popping bubbles with needles, which is inadvisable as needles introduce bacteria that can corrode the film and create cracks.
