It is unlikely that in the near future there will be a paint and varnish coating that is not afraid of weathering, “sandblasting”, and this is why it is necessary to protect it. For example, self-adhesive films. Today there are many of them - from transparent, colorless, preserving the factory appearance of the car, to those that give it a defiant personality. If you wish, you can “chrome”, “gild”, put on carbon, “anaconda leather”, “mammoth skin” … The basis of these films is usually polyvinyl chloride (colloquially called vinyl) or polyurethane.

By the method of production, the films also differ. There are calendered structures with increased rigidity - and unsuitable for a car: they crack on curved surfaces. For us, cast films are better able to stretch even when cold. This allows you to stick them on the details of the most complex configurations. Nevertheless, it is sometimes useful to add elasticity to them by heating with a hairdryer.

For reliable fixation of any film, the manufacturer uses a special adhesive with good adhesion. And at the same time it stipulates the service life, otherwise it is very difficult to remove the old film (more precisely, traces of glue). But experts have the appropriate chemicals.

To prepare the surfaces for gluing there are effective compounds. We wipe the parts with microfiber cloths that do not leave a lint

HARDER - NOT BETTER

The thickness of the vinyl film is 0.05–0.11 mm, and the polyurethane film is 0.2 mm. The advantage of vinyl is its relatively low price: about 700 rubles per square meter compared to 2500 rubles for polyurethane. But the vinyl film is thinner and less elastic, so the pebbles easily pierce it. Vinyl is tolerant only to fine sand.

How to distinguish them by touch? If the film is torn quite readily when stretched, it is vinyl. She stood and stubbornly stretches, slightly resembling rubber - polyurethane. Vinyl is easy to pierce with the ignition key, polyurethane is difficult. The latter is elastic even in a 20-degree frost. With a thickness of 0.2 mm, it keeps good impacts of small stones and protects bumpers from scratches. Shallow damage can be polished. But many are constrained by the price, forcing to paste over only the most vulnerable places - the front bumper, hood and wings, mirror housings, headlights. Some companies already use polyurethane on new cars, protecting chrome surfaces, wheel arches, sills, radiator grilles, etc.

When working, you have to spray a lot of liquid. The task is facilitated by bottles with an integrated pump. Pumped up - and work without straining your hands. And for small surfaces, a conventional spray gun will do

WHAT, HOW AND WHY TO WET

Vinyl films, depending on the manufacturer's recommendations, can be placed both on a dry surface and on a wetted soap solution. Polyurethane - only on wet, as their plus - high elasticity - in combination with sticky glue can turn into a minus: it is difficult to dry such a sticker evenly on the surface of the machine. The recipe for a slippery solution is simple: two to three drops of shampoo per liter of water. Apply it to the body with a conventional hand spray.

We prepare film patterns in advance. If you act the old fashioned way, it can be difficult and costly. The surface configuration of a modern car is so complicated that only a very talented tailor can cut out patterns from a newspaper! A mere mortal is better to turn to specialists. So did we, preparing this material. The company "3M" - the owner of an extensive database of templates, patterns for a variety of brands and models. The customer should only clearly state what he wants for his money. Ours decided to protect only the front end of the Mazda CX-5 with polyurethane - and soon received ready-made patterns. We confirm: it is convenient. And you will not spoil a precious piece of material.

We expel water from under the film with squeegee plates from plastic or rubber. Some plastic squeegees have a soft pad that protects the film from scratches

But where and how to work? The main enemies of the master are dust, dirt, ubiquitous onlookers, and in the summer also midges. First, the body was thoroughly washed with shampoo using a high-pressure installation, so that even in secluded places there was no dirt left. Further action took place indoors, after thorough cleaning. No dust, let alone repaired cars in the neighborhood! Here, the paintwork was cleaned of the slightest trace of dirt, insects, poplar buds, bitumen, tar. They didn’t even smoke nearby … Than they cleaned - it makes no sense to list. All this has long been for sale. The only material unknown to the general public is blue abrasive clay, which effectively collects not even dirt from the body, but the last hints of it. It employs professionals. At the end, they wiped the surfaces with microfiber cloths that did not leave fibers and stains. But this is not all: when it is separated from the substrate, the film instantly becomes electrified - and immediately attract dust particles, which will settle on the adhesive layer. Therefore, immediately, already in the process of separation, we pour the adhesive layer with a soap solution.

WARMING OR DO NOT WARM?

Having wetted the surface of the adhesive layer and the body, you can easily move and correctly orient the future sticker. Although its dimensions are selected by the company, taking into account the allowance for the bend (for example, under the edges of the hood), it’s better not to be mistaken. Then, pressing the film, the master gradually - from the middle to the edges - squeezes water from under it with soft squeegees (a kind of scraper) from rubber or plastic. To minimize the risk of scratching the film, even the squeegees are wetted for fidelity. This painstaking work takes a lot of time and energy! The same places on the film have to be smoothed over many times. Were it vinyl, it would be hard to lay without heating. But we have polyurethane. If you need a hair dryer with it, it is mainly for drying the places where the film is bent under the edges of the hood, because here the moisture lasts longer. If there is no hairdryer, then the evaporation of water and drying of the glue can be accelerated by injecting a 25 percent solution of isopropyl alcohol here.

For the final cleaning of the surface, professionals use special 3M blue clay. Outwardly, it resembles children's plasticine

CUT OR NO?

Sometimes, alas, the film has to be cut, or even glued back to back from several parts. Often they do this by pasting, for example, headlights with diffusers of a sophisticated configuration. To facilitate these operations, it is also better to use patterns previously prepared by the company. This is what our customer did.

But let's imagine that the film was glued in good faith, the edges were bent, dried … and then we found a random, extremely annoying bubble! Do not get excited and tear off the film in order to remove it. The glue layer will be damaged - and re-grasp weaker. The easiest way to remove large bubbles is by sucking water or air with a thin syringe medical syringe. And small bubbles after some time (usually enough 48 hours) disappear themselves.

OPERATING CONDITIONS

At the end of all procedures, the car should not be washed for at least a day, because the setting of glue is not an instant process. And if the work was carried out in the winter, in a warm room, then it is better to leave the car in it for the night, and not to drive it out immediately in the cold. In the future, the glued car can tolerate even a high-pressure wash, but still it is necessary to warn the washers what they are dealing with. And after all, having brought the nozzle to the body too close, to tear off any film for a short time - this is a disservice to you!
