What is the procedure for car wraps? How to paste it?

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 large curvature.

Before the film, it is necessary to check whether the installation of the window glass is intact and the integrity of the car glass to ensure that the subsequent film work can operate normally.

Be sure to cover the necessary parts of the car before applying the film to prevent liquid from penetrating. Sprayed cleaning fluids and lubricating fluids can affect trim parts such as automotive electronics and interior seats.

Wash the interior and exterior surfaces of the windows before applying the film (focusing on the interior surfaces and glass sealant areas). This is mainly to eliminate the dirt or other object construction quality problems between the heat insulation film and the window glass after the film, and ensure that the film and glass can be perfectly combined.

The membrane is pre-cut. Use a ruler to measure the size of the front and rear windshields, and cut the film according to the measured size. (The professional film mechanism is through the computer, which is tailored according to the model).

Spray the installation fluid. Dust spots can be avoided and corrosion at the edges can be reduced, resulting in the desired viscosity and better application results.

Dry roasting, wet roasting shaping. The film is dry-roasted first so that the film can be fully pre-shrunk. In order to further improve the adhesion of the heat insulation film, it is also necessary to wet bake and shape the heat insulation film.

Extrusion of the installation fluid: In the process of using the wiper to remove the installation fluid, try to scrape the installation fluid between the heat insulation film and the window glass, which can reduce the drying time of the heat insulation film and obtain a better bonding effect, overall performance and visual effect.

Check after sticking. "Three looks and one attention": look at the entire heat insulation film to see if there is any dust and bubbles, see whether the corners are firmly glued, and sit in the car to see if there are any places that affect the line of sight (especially the front windshield and side windshield). After the film, it is recommended not to raise or lower the glass arbitrarily within 48 hours.

The most important thing to pay attention to when applying the film is the use of hair dryer, if you blow this place for a long time, it will cause the glass to crack due to uneven heating. Therefore, it is necessary to find those professional authorized stores for the film, so that the quality of the film will be the best and the danger of glass cracking can be avoided.

Also, the car film is best in rainy weather, and when it is pasted on rainy days, there is very little dust in the air, which has certain benefits for aesthetics.

First take a bath in the car, then go to the clean room to wash the glass, and wait for the film. Holding a hair dryer and coaxing and blowing, I only see this point, and other programs may not know about it.

1. External cleaning, move along the car in a clockwise direction, the outside of each piece of glass should be well cleaned 2, the wheel gallery is cut, a small amount of window film installation liquid is sprayed on the outer surface of the window glass, the film is covered on it, the peel film is facing outward, and the slide is carefully sliding, 3. Bake the film and use a heat gun to set the shape

The methods and steps of car film are as follows:

1. Spread the solar film on the front windshield first, then blow it with a hair dryer to deform it, and smooth the solar film by hand while blowing to make it extend, which can fit the curvature of the glass;

2. Use a special tool to scrape the solar film flat, so that the film completely fits the front windshield. Use a knife to cut the film into the desired shape, and then remove the various annual inspection signs pasted on the windshield;

3. Gently take off the film that has been extended and cut the shape, spray the mixture of water and washing spirit on the front windshield, and then wipe all the dirty things on the glass clean, and then spray the mixture of water and washing spirit after wiping it clean;

4. Tear off the adhesive and gently stick the film on the glass stained with water and washing spirit mixture according to the shape cut before. Use a tool to expel all the water and bubbles between the solar film and the glass.

The steps are as follows: 1. Before the film, first ensure that the working environment meets the requirements of dryness and less dust, otherwise dust and debris will enter during work, which will affect the effect of the film. It is recommended to wash the car before applying the film.

2. Cover the necessary position of the vehicle, and protect the interior and exterior with a protective cover, if there is no special material, you can also choose plastic wrap.

3. Clean the car glass that needs to be filmed, pay attention to the top and edge of the glass, and then wipe the water.

4. The next step is to cut the car film, pay attention to the size of the car film to match the glass. Spray a little water on the surface of the glass, then adsorb a certain thickness of plastic film to the window, and then draw a pattern according to the edges, the template can be a little more than the glass.

5. When the front and rear windshields are filmed, the baking film also needs to be shaped. The key step is to cover the outside of the glass with the cut film and then use a heat gun to shape it.

Car wrap tool preparation.

Explosion-proof film pasting tools mainly include glass cleaning brushes, wipers, wipers, shaping scrapers, utility knives, watering cans, hot air blowers, etc.

Glass cleaning. Use a special glass cleaner to remove dirt from the glass as well as dust.

Cover. Cover the areas that will get dirty in the film, such as the lead and the door.

Cutting and blanking. First, measure the size of the glass to be filmed, then cut out the basic suitable film, and then stick the cut film on the wet glass, and trim it according to the shape of the glass.

Stereotypes. Because the front and rear window glass (and some side window glasses) have a slight spherical bending, which prevents the film from being flattened on the glass and is prone to wrinkles, the film should be shaped after cutting. The method is to heat the membrane with a hot air blower, and while heating, it is squeezed with a plastic scraper until it fits perfectly with the curved surface of the glass.

Internal cleaning. The adhesive surface of the glass should be further cleaned before pasting, and then the glass should be scraped clean and the frame should be wiped clean with a soft cloth and scrubbing paper.

Spray the installation fluid. After the inner surface of the glass is cleaned, the protective layer of the explosion-proof film is torn off first, and then the installation fluid is sprayed on the film and the inner surface of the glass respectively.

Paving. As the adhesive surface on the membrane temporarily loses its stickiness due to the spraying of the mounting fluid, the membrane glides smoothly on the clean glass inner surface, ensuring that the membrane can be adhered in place.

Squeeze water to dry. When the membrane is stabilized in its final position, the membrane surface should be sprayed again with wine installation fluid to lubricate the surface to be squeezed. A special squeezing tool is then used to remove all "bubbles" and as much mounting fluid as possible.

Scrape the film from the center to the edges, from top to bottom and then to the bottom so that excess water drains out of the window frame. Finally, wipe the edge of the glass with a towel to dry the moisture and mounting fluid.

Car film cleaning inspection.

Once installed, scrub the inner and outer surfaces of all window glass to remove streaks and smudges. Finally, the paste quality should be carefully checked. One is to check whether the paste is firm, especially the corners; the second is to check whether there are bubbles; the third is to check whether the membrane is wrinkled; Fourth, check whether there are scratches.

If a problem is found, it should be reworked.

Car Foil Steps (for Windows & Windshield): 1First of all, you need to measure the size of the glass and cut it according to the size.

It's okay to be a little bigger, but it must not be smaller, because it will shrink a little after the hot air is blown. 2.Then use a special car wash liquid to clean the car glass, especially the obvious stains, be sure to clean it.

In addition, residual water needs to be removed after cleaning. 3.Then you can apply the film, heat the car film (hot air blower), spray a layer of glue (mainly water) on the effective film surface, and then smooth the film a little from top to bottom.

If the size is still large at this point, the additional film will have to be cut. 4.If air bubbles are found after pasting, they must be scraped off with a soft scraper.

It doesn't matter if the bubble doesn't blow off. The sun will disappear in a few days.
