Second, add two or three drops of finger-sized flexible detergent (mainly used for cleaning and lubrication) to the glass jar and shake it with water. Spray an appropriate amount of water on the outside of the glass to be pasted, carefully clean the whole glass with a steel scraper or a plastic scraper to remove dirt on the glass, spray water on it, and then clean the glass again with a special wiper for the front and rear blocks. If the film is baked on unclean glass, when the film becomes soft after heating, scraping things on the glass with a scraper will leave traces on the film. These marks can't be removed even if the film is pasted, which affects the quality, beauty and clarity of the film.
Third, the plastic teeth before baking the film bite the corners of the film, thus distinguishing the side with protective film. Spread the protective film with one side facing up evenly on the glass, and cut off more parts (subject to the black edge of the glass). The upper and lower sides of the membrane are evenly separated from the middle, and the two wide-sided bubbles are evenly separated from the upper and lower sides together. Scrape the water in the middle part with a wiper, and be careful not to scratch bubbles to prevent scratching the film. The middle part is rubbed first for setting, so that the solar film will not move, and the bubbles of the film will be evenly separated on both sides, which is beneficial to baking the film.
Fourth, bake the film and divide the bubbles into equal parts of similar size. From easy to difficult, bake small bubbles first. After the small bubbles are baked, bake the big bubbles into small ones. Pay attention to the temperature of the drying gun and the heating degree of the film when drying the film. You can adjust the temperature by distance or speed. When baking bubbles, the bubbles should be heated evenly, and the baking gun can keep it for 1-2 minutes to make the film edge shrink and then flatten it. Pay attention to the shrinkage of the film when baking. When the film shrinks into wrinkles, scrape it to the bottom with a scraper. If the bubbles are too big, you can smooth the film by hand and scrape it clean with a scraper. When baking the film, you can't stay on a bubble for too long to avoid being too hot. If the temperature is too high, the film will burn lightly and the glass will burst. This is not allowed to spray water on the car glass to prevent the glass from bursting because it can't stand the stimulation.
5. After trimming and baking a piece of film, cut off more edges. The front windshield has a rearview mirror, and 2mm from the black side is enough. Glass trimming requirements: straight, flat and even.
