Statistics say that every fourth car for 5 years of operation, gets a windshield injury. Having found a crack, the driver becomes before the problem of replacing windshield. But given the "sophistication" of modern cars and windshield is no exception, since many cars have heated windshield, rain sensors, etc. The cost of replacing windshield is a considerable amount, and especially at present, when the ruble devaluation is devalued. The owner of the car should take into account such "nuances" and if it is obligated for him, the driver can try to stop the process of promotion of cracks on the windshield with their own hands.

Crack on the windshield than it threatens and how it arises

According to the rules of the road, the driver does not have the right to operate vehicles if the driver appears on the front glass, a crack appears on the driver.

Such a ban is justified by the fact that the occurrence of a crack or chip on the windshield of the car leads to the difficulty of perception by the driver of the road, especially at dusk and at night due to the fact that the glass damage provokes a strong dispersion of light.

Before deciding to repair the windshield, the owner of the vehicle should know that not any damage to the windshield is subject to repair. If the crack started from the edge of the glass or approached the edge of the glass closer than 5 cm. From the edge - you do not restore the glass and will have to replace it. The crack on the windshield, mostly, occurs from the stone impact in the windshield of the car.

Frequently on the roads are spacing a mixture of stones with asphalt, rubbank, etc. And our modern roads are significantly loaded and often from under the vehicle wheels, stones are departed at a huge speed, the speed of the stone reaches more than 200 km / h.

And even a small stone, with his huge speed, hitting the glass, causes cracks.

A crack can be not only one but in the form of a clock of rays, length and the depth of cracks is different.

The windshield, having even a small damage, has a point on its area in which the voltage concentrates.

Even small loads lead to the destruction of the glass.

And if you did not immediately stop the crack, then during the operation of the car for one month, having a fracture at the initial stage with a length of 1 cm, at the end of the month you will get a crack length 6 cm.

Crack on the windshield, how to remove it with your own hands

The technology of work to eliminate cracks occurs in two stages.

At the first stage, before the driver, the task is to stop the crack.

The second stage is to eliminate the crack.

Below we describe work at these stages in more detail.

Windshield crack, windshield repair, how to stop the crack

The end of the crack has a slight rounding, this rounding is a point in which the voltage concentrates.

Even a small force creates a huge pressure and leads to the rupture of the solid surface of the glass.

It means that the driver is faced with the task to remove this rounding at the end of the crack. The mistake of most motorists is the drilling of the hole at the end of the crack.

Since the end of the crack in reality is not visible to the eye and is located at a distance of 5 mm. From what sees the eyes.

Total to drill is needed at a distance of 5 mm. Further than the rounding crack is.

Now it is necessary to determine the depth of drilling.

Since the windshield consists of three layers, the outer two layers are rotable glass and inside, between the glasses is a film that protects the glass from the scattering.

Usually, having hitting the windshield, the crack stops at the film. However, a strong blow can provoke glass damage through all layers.

To determine the depth of the crack, take a thin needle in the hands and spend the crack if the needle passed through, you've gotten through the crack and you will have to drill the glass thickness if the needle rested into the obstacle, the crack came only to the film and you need to drill only Outer layer.

Important! Use drill only with diamond spraying.

We recommend purchasing a repair kit for glass, in the set there is a drill with a diamond spraying.

You can buy and just drill separately. You need to drill on the minimum turnover of a drill with mandatory cooling.

Kerosene or machine oil can be used as a cooler. If you have purchased a glass repair kit, it has special mirrors, with which you can determine the depth of the crack and, respectively, the drilling depth.

The depth of drilling, if the crack reached the film, is determined by the presence of a characteristic haze.

When drilling, it is necessary to use the drill no less crack width, usually use a 1.5-2 mm drill.

After drilled a hole, it must be carefully cleaned from glass dust.

Repair specialists offer to use rubber pear. The purified opening must be filled with special glue or optical polymer.

This composition can be bought in a car shop, and if you have a repair kit for glass, it contains this special glue and plastic injector.

The plastic injector will help fill the opening of the optical polymer without creating aircraft and shakes the polymer directly into the crack itself near the opening.

In the absence of a plastic injector, use a medical syringe without a needle.

If the crack turned out to be through, from the inside of the glass, install the rubber suction cup on the through hole.

After downloading the polymer into a crack, it is necessary to irradiate the infrared lamp.

Infrared rays will speed up the polymerization process.

If there is no infrared lamp, the polymerization process will lengthen and have to wait for several hours.

After the polymer freezes, pass the place of damage to polishing paste.

If a crack in the form of an asterisk was formed on your windshield, you will have a lot to work hard and carry out the above operation for each beam.

The crack of the windshield, repairing windshield, how to close the crack with your own hands

In the previous section, we stopped the promotion of the crack, now it is necessary to close this crack. 90% of the seeding of cracks, depends on how carefully you clean the crack itself.

Therefore, you have a task, rinse a crack under pressure degreaser.

For washing, you can use the above injector or syringe. After careful flushing, the crack must be dried.

Then, using an injector or syringe, fill the optical polymer into the crack.

The polymer use more fluid than to stop cracks.

The work is performed similar to the work on stopping cracks.

Then we produce a casting of the polymer using an infrared lamp or just wait until driving in air and polished polishing pastes.

Based on the indicators, if you do everything neatly with the observance of the above-described technology, you can reach cracks with an optical transparency of 95% of the intact glass.

All the above works can be made on the car service, but they will take money with you.
