Generally, junior technicians can only apply film to the side windows, while only intermediate and senior technicians can apply film to the front windshield with a larger curvature

■Check the car before applying the film Whether the installation of the window glass is complete and the integrity of the car glass is required to ensure that the subsequent film application work can run normally.

■Be sure to cover the necessary parts of the car before applying the film to prevent liquid from penetrating. Sprayed cleaning fluid and lubricant will affect vehicle electronic equipment and decorative parts such as vehicle seats.

■Clean the inner and outer surfaces of the car window before applying the film (focusing on the cleaning of the inner surface and glass sealant area). This is mainly to eliminate dirt or other construction quality problems between the insulation film and the window glass after the film is applied, and to ensure that the film and glass can be perfectly combined.

■Membrane pre-cut. Use a ruler to measure the size of the front and rear windshield glass, and cut the film according to the measured size. (The professional film sticking mechanism uses a computer to cut the film according to the car model)

■Spray installation fluid. It can avoid dust spots and reduce edge corrosion, obtain the viscosity required for shaping and achieve better construction results.

■Dry roasting, wet roasting and shaping. Dry bake the insulation film first so that the insulation film can fully pre-shrink. To further improve the adhesion of the thermal insulation film, the thermal insulation film also needs to be wet-baked and shaped.

■Squeeze out the installation fluid: When using a wiper to remove the installation fluid, try to scrape off the installation fluid between the insulation film and the window glass, which can reduce the drying time of the insulation film. , to obtain better bonding effect, overall performance and visual effect.

■Inspection after pasting. "Three Looks and One Attention": Check the entire insulation film for dust and bubbles, check whether the corners are firmly adhered, and sit in the car to check whether there are any places that affect the line of sight (especially the front and side shields). After applying the film, it is recommended not to raise or lower the glass at will within 48 hours.

When applying the film, the most important thing to pay attention to is the use of a hair dryer. If you blow hard on this area for a long time, it will cause the glass to be heated unevenly and crack. Therefore, it is necessary to find those professional authorized stores for film application, so that the quality of the film can be guaranteed and the risk of glass cracking can be avoided.

Also, car films are best applied in rainy weather. When applied in rainy days, there is very little flying dust in the air, which has certain benefits for the appearance.
