What are the steps of car window film? All window films will age slowly with time and must be removed. The two signs of film aging are purple and bubbles. The nonmetallic dyes in the film decompose and change color, forming a purple film. As for foaming, it is caused by the failure of the adhesive that sticks the film to the window. After a bubble appears, there will be more bubbles. If you try to tear off the film, there may be sticky residue on the glass window, which will take several hours to clean. At this time, you have to remove the window film and re-film it. Tearing off the glass film mainly includes the following steps:
1. Tear a hole at will with wallpaper knife.
2. Tear the automobile glass film by hand, and try not to break the film properly.
3. Use a knife when it is difficult to tear until it is completely torn.
4, in addition to glue. There will be a lot of gum left on the glass, which needs to be removed bit by bit with a glue remover, scraper and rag.
5, drying. After the film is torn off, there will be some peculiar smell, which can be removed by ventilation and exposure.
Tips for removing automobile glass film:
1. When removing the film near the defogging line, pull up the film with adhesive tape instead of scraping it with a blade. If there is sticky residue, it can be wiped clean with ammonia or Windex cleaner and an old towel.
2. When scraping the film with a blade, the blade may become dull. You may need to scrape it clean with several blades.
You can also heat the film with a heating lamp or a floodlight (for example, a 500-watt studio lamp). Put the lamp 30 to 45 cm away from the window. When heating the film with a lamp, spray ammonia water to keep the film moist and cover it with a plastic film. Heat for 30 to 45 minutes to peel off the car film as completely as possible. Residual glue can usually be scraped off with a non-carbon steel blade, and warm soapy water is sprayed to keep it moist when scraping.
