DIY repair of glass cracks and sealing chips. Repair of car windows: cracks, chips, scratches of Cao, CJSC, YUAO, UNUSAO, JUVAW than process chip on the windshield

Skol is not a crack, but the chip seal procedure is no less problematic than the repair of windshield cracks.

What for? At least in order to take preventive measures to help you in the future cope with the scola repair procedure on the windshield. Do not be lazy, creek the place of the chip with transparent scotch - then it will then reduce the process of cleaning the defect from dirt.

Why does such attention chick on the glass? Elementally simple. On time, the repair of windshield chips allows you to stop the process of turning the chip in the crack, and avoid a more cost procedure-repair cracks on the windshield of your car. Choose, you are a practical and sensible person.

Repair of chips on the windshield does not require much professionalism and deep knowledge of the device internal combustion engine. Total need: Your desire, "field" set "ambulance" for glass in the form, for example, a set for repairing the windshield "Abro" and time.

Why Abro? Not necessary. The set can be any manufacturer which you choose in the auto shop. The main thing is that it is equipped and the shelf life corresponded. Otherwise, the polymer applied to the chief, or not "take", or will have a low transparency coefficient, and even the glass polishing will not help you.

The cost of recruitment for repairing windshield samples is many times less than the amount you will hear in the service. And the choice naturally is yours. But the chips for the season can be somewhat, then, probably, it is easier to change the car immediately. Repair of windshield choles for you. Do not doubt.

How to close the chip on the windshield?

The sealing of chips on the windshield is desirable to produce in the garage and with the corresponding sunny weather. Although it is not an axiom. No weather - there is a hair dryer or a construction hairdryer of a neighbor. There is always a way out.

Evaluation of degree of defect. With the help of a flashlight, appreciate the area of \u200b\u200bthe chip, and can be microcracks, which are unnoticed by the naked eye. If, yes, the edges of the cracks must be sealing to prevent cracking. For this you need: an electric drill and diamond drill.

Skol preparation to repair. If there are no cracks, then continue the repair of windshield chips using a set. Clean the defect area thoroughly: Remove, rinse dust, dirt, microker glass from the chip cavity. Thoroughly dry the place of the chip with a hair dryer. It is not recommended to wash the place of repair using chemistry - a film is formed, which will prevent the polymer, perform its work. Just water and tassel or needle from the set. Degrease the place of chip alcohol.

Installation of a mini-injector. In the repair kit there is a self-adhesive "circle" and a plastic "nipple" for a syringe. This is an improvised one-time injector. We produce its installation according to the instructions.

Polymer preparation. Syringe from the set fill out of two tanks (if the polymer is one-component, it is even easier, you do not need to mix).

Polymerization process. We establish a syringe into the "nipple" and make several pumping: discharge - 4-6 minutes, overpressure - 8-10 minutes, again discharge. In fact, these procedures are carried out by the manufacturer of the scroll repair, describes in detail in the instructions.

Includes a special metal bracket for fixing the syringe to the nipple of the injector. After creating a pressure in the syringe, the design is left for the time specified in the instructions. As a rule, 4-6 hours.

The final stage - cleaning the place of repair from the excess polymer. We remove the injector and blade or the construction knife we \u200b\u200bremove excess glue. But, finally, the polymer hardens for 8-10 hours.

Everything. Repair of windshield chips are made, it is possible to polish the place of repair or, since it took, all the windshield. The goal is achieved, the chip is eliminated, the risk of cracking on the windshield is minimized. Let's hit the road. Let it easily be possible to repair chips on the windshield.

Good luck to you, lovers of their car.

The windshield of the car may be damaged by different reasons: as a result of temperature drop (for example, due to the power on the air conditioner in a strongly heated machine), and mechanically stones flying out of the wheels of other cars. And if you do not have full insurance (autocarter does not count - this is an insurance is not your car, and the one in which you, God forbid, drink), it turns out the fall in the same place. It's a shame, it seems like not to blame, and problems arose. The cost of the new glass is quite high, and the installation is not cheap, in most cases, it is much more profitable to execute local repair of automotive glassUsing the right methodology and reliable professional methods.

And here there are two options - choose a car workshop and trusted professionals (here is also not everything goes smoothly) or make yourself repairing your affected automotive glass. In any case, what and how it will be done will be useful to know if we decided not to change the glass completely. Of course, the choice depends on the nature and size of damage.

In modern cars, two main types of glasses are applied - hardened or three-layer. Three-layer glasses consist of two layers of glass and polymer between them. The tempered glass is subjected to a heat treatment cycle, which makes them stronger and in case of destruction prevents sharp edges on fragments, ensuring the safety of passengers.
Glasses are attached to the body by inclination or rubber seal. The first method is more modern and prevents glass loss with a strong impact. The second method is cheaper, but rubber with time begins to lose elasticity, stops protecting the salon from moisture.

In general, under the repair of glasses it is understood by the sealing of abrasion and chips. By definition, such an embelling restores the strength of the glass and makes defects that were on glass, poorly spare. By itself, the chip consists of a lost piece of glass and internal damage. To get rid of it, the inner portion and the crack are filled with a special polymer. Filling occurs with the help of a special injector, and the polymer used to fill, has the same optical properties, the same refractive index of light as glass. After the polymer is applied, the internal cavities of the chip or cracks are reliably adhered. The polymer hardened under the influence of ultraviolet rays, and after all this glass is polished and becomes a new appearance. Such an action is beneficial in the event that damage is not very serious. After this procedure, the strength of the glass is restored by 87-97%. And this, you see, very, very good.
Now in more detail.

For high-quality repair of auto glass requires professional tools. Typical set is shown below in the picture.

Major damage to auto glass and their repair

Skol.
Schole looks like a small hole on the glass. Most often, it appears due to a sharp ingress of gravel or small pebbles that arrive from under the wheels of other cars.
Most often, the chip does not deteriorate significantly, but weakens the glass and can trigger the appearance of cracks in several directions around damage. Cracks around the chip can quickly arise in the cold season. It is much easier to repair the chip, than the resulting cracks.

How to repair chips?
Screen repair is usually made using an injector and a special polymer. The injector for the repair of chips has an internal piston. Lifting up, the piston creates a vacuum, and the damage is filled with a polymer. In the same way, you can "cure" and cracks on the glass, but it is better to repair at the time until the church is still filled with mud and has not been transformed into a huge, ugly crack.

Crack
The crack is much more annoying and serious trouble than chip. Even a small crack is already limiting visibility, sometimes refracting the light entering it. In addition, at any time the crack can split on the "web" from the surrounding minor branches. And also - with a large crack on the glass, you can easily not pass the inspection.

Causes of cracks:
● Most often cracks, like chips, arise from the random "arriving" in the glass of an outsider.
● On some models, the car can occur due to inconspicuous, but permanent movements and body swaying, which ultimately deform the body itself, and windshield itself.
● Initially low quality glass. Sometimes glass on the car is replaced by the option from manufacturers from the side. Such glasses are not very plastic, and the crack may occur even from a sharp drop temperature.
● The risk of cracking is especially high in the cold season: especially if a small amount of moisture falls into the microframing.
● The crack can develop from a small chip in the event of a sharp braking or other sudden car shake. Therefore, it is important to carefully inspect the windshield for the presence of chips when buying a used machine.

How to repair cracks?
Polymer is used to repair cracks, the penetrating ability of which is very high. The crack is filled with material that makes damage almost inconspicuous. But, as in the case of chips, the earlier start repairing - the less unpleasant consequences can expect your car in the future.

The success of the repair of cracks on the glass can prevent such factors such as:
- getting into the crack of dirt and dust that will not allow the polymer to completely close the defect;
- detachment of the plastic layer of glass at a strong impact. Such damage is difficult to eliminate even with a polymer, since the glass will remain muddy due to damage to the middle layer;
- Different optical characteristics of glass and polymer, which are not always able to perfectly combine.

Crack repair process on glass
When repairing from a crack, the voltage is first removed, which prevents its further growth. After this, damage is filled with a polymer with a similar refractive index, the composition is frozen and reliably records the edges of the crack.
In the injector for repairing cracks there is an inner piston, which is screwed and unscrewed with threads. The piston creates a pressure that allows the polymer to divently disperse along the entire length of the crack.

For independent repairs It is necessary to buy a ready-made kit for such cases in a special store, as a rule, consisting of a special device on suction cups used for convenient contact with glass, sealant based on synthetic resins and a thin film to cover the drying zone. You also need a drill (with a diamond tip), polyrolol (quartz sands, corundum, essay ...) and nozzles for polishing.

The total crack repair algorithm looks like this:

● Initially, you need to stop the crack so that it does not start develop further. For this, there are two small chips on the sides of damage, which stop the propagation of the crack. Typically, the edges of the crack are treated with a diamond drill.

● The damage area is cleared: the dirt is removed, the chief is carefully dried and cleared of dirt and dust particles.
● Install the tool on the suction cups on the windshield so that its four legs are placed around the crack, and the central hole was strictly over the crack itself. Then insert a tube with a resin into this hole and squeeze it to enter three four droplets of the resin directly into the crack. Further, you can remove the tube, and insert the piston instead, which will tighten the grip with the windshield to "pull" two edges of the crack.

● You can distribute the glue evenly using a special finishing film. It must be laid from the center to the edges so that there are no air bubbles inside.
● After filling, the crack is dried with an ultraviolet lamp. Such a lamp significantly reduces drying time. In addition, if the glue will dry in the sun, there is a high probability of cloudy.

● Upon completion of the pouring of the polymer, the film and excess substances are carefully removed. The remnants of the adhesive can be carefully removed by the blade or other flat object.
● The process ends with glass polishing, using special paste.

Professionally completed repair of windshields makes cracks with almost imperceptible, however, to restore 100% optical transparency and glass hardness is impossible. Complete winding windshield repair with a vacuum cleaner of small fragments, this procedure is especially necessary if the operations were carried out on the inside of the glass.
However, if the cracks are too much or their length is significant, it is advisable to completely replace the windshield to the new one.

Several recommendations that you need and what do not be done immediately after getting a crack or chipped or any other automotive glass

Immediately after the acquisition of a defect on the glass, it is recommended to make a damaged place of scotch. Scotch helps to prevent dust, water or dirt from entering a defective glass section: which significantly facilitates the repair and allows you to perform it better.
- In the cold time, blowing the stove is better to send down - towards the legs.
- On a warm day under the tape, it is better to put the paper to glue Scotch's glue to damage.
- If you have to postpone repair for a while, then avoid washing glass using special chemical detergents. Once in a crack, these substances can after lead to the fact that the glue for the cracks of the windshield is not polymerized enough.
- To the place of repair is better to go to the minimum speed, because the vibration and push of the car body cause cracking.

Prevention of cracks and protection of car windows

To avoid the appearance of cracks or the growth of already existing damage, you need to remember some important points in the operation of the car:

● In the cold season, you should not install the stove regulator immediately to the maximum and direct the entire flow of heat to the windshield. Salon need to warm up gradually after cleaning from snow or ice.
● In the summer, the same recommendation is applicable to the air conditioner: it is not necessary to immediately install it for maximum cooling and blowing the glass.
● In winter, it is not necessary to turn on the wipers if you are adhesive to them. They need to be cleaned or wait until the pieces of ice are melted. If the machine remains in the cold for a long time - the wipers need to bend: so that they do not
stuck to glass. Old wipers need to be replaced, especially if they crush and hide the glass when working.
● Pollution from glass is better to remove special means using a soft cloth or sponge.
● Periodic polishing prevents glass from microcracks and scratches.

Anyway happens on the road. A fairly frequent situation when various kinds of chip and crack appear on the windshield. For their appearance there are a lot of reasons: the main one, it is bouncing from the wheels of counter-car stones, as we have a lot of gravel roads. In addition, there may be fallen objects, and even the actions of hooligans. And if you have found chip or crack on the windshield, without losing time, it should be done by replacing the windshield, or its repair, because it is not recommended to ride with damaged windshield, and there are several reasons for this.

1. Damaged windshield distracts the driver from the road, it makes it difficult.

2. Cracks, subsequently, have a property to grow, which leads to future scattering windshield.

3. And the most basic reason is that the damaged windshield is a major interference if time has come for a technical inspection of the car.

If you suddenly detected a chip or a small crack, it is not necessary to immediately rush to the car market and, in some cases, it can be repaired in the car service. It will cost you much cheaper, because it is not enough to buy it, the installation also costs a lot of money. In addition, replaced windshield, it is a serious stumbling block when selling a car. You will not prove to the buyer, for what reason did you replace it, suddenly there was a crash?

If you find a small crack or bulk glass on your windshield, first of all, capture damaged area Special vinyl film, or ordinary transparent scotch. This will protect the damaged place from the dirt falling inside the crack, as if dust or dirt fall into cracks, it will seriously increase the cost of repairs. It also happens that in the car service and do not restore windy windows, in the cracks of which dirt hit.

If immediately after the formation of damage repair does not work, then do not wash the glass with chemical detergents. They will not let adhesive as it should be polymed.

Repair of damaged windshield is performed by pouring special polymers inside chipping and cracks. These polymers have very good optical properties that, in transparency, are not inferior to ordinary glass. Also, such polymers have good shock resistant.

An important factor consists in choosing a suitable car service for work. After all, the cost of work, in each individual car repair shop, can differ significantly. Therefore, before starting repair, show the "work front" to the car mechanic so that he immediately told you how much you will cost you.

If, at the moment, financial problems do not allow you to immediately begin repairing windshield, you can ask the wizard temporarily, just sewer crack. So, you will prevent further cracking, besides, it is an inexpensive operation. By this, you will be able to save money when there is already serious repairs.

By the way, the repair of chips and cracks will be quite admissible, because it is not always car services taken for such work, it is easier for them to change the windshield completely. And if you fully follow the technology of repair, you can easily do everything yourself, the benefit of the necessary materials are sold everywhere.

Equipment and materials for repairing windshields.

So, let's list what is necessary in order to eliminate the chip or crack on the windshield with your own hands.

• Glue-polymer For climbing cracks. When buying, you need to remember that the time of its solidification should be small. As for transparency, each product has its own transparency coefficient, and it must correspond to the glass indicator.
• Electric drillwhich can be removed from the glass. That is, drill holes around the edges of the crack so that it does not grow. The drill must necessarily take the diamond.
• Bridge and injector. Asimes, the glue is introduced into the crack. They go disposable (plastic), and reusable (metallic).
• Pump. They are removed by air from the damaged space.
• Scruber. Need to cleanse the place around the damage.
• Electric flashlight, To clarify the boundaries of the crack, and to detect bubbles in the glue.
• To speed up the process of drying the polymer, useful ultraviolet lamp.

Well, in order to clean the surface, prepare the cleansing liquid and napkins.

How to remove chips and cracks on the windshield?

The area of \u200b\u200bwork must be thoroughly rinsed and dried, because the remaining moisture and dirt will not give adhesive to how damage should be filled. Clean the crack carefully, with the help of the blade, remove the fragments and the fine garbage. After that, blow a damaged place with the compressor or pump, and you can proceed to work. And try to make a straight sun rays on the glass.

First of all, you need to "remove the stress" with a damaged place to ensure that the crack is even more in the process of operation. For this, along the edges of the crack, drive through the through hole, at a distance of 2 mm in the direction of elongation. Then, putting a little effort, bring the crack to these holes.

Install a bridge with an injector so that the hussak is right above the desired place.

Slowly serve glue polymer into a crack. Purchase glue about the reserve. Remove the extra polymer is easy, but if it is not enough, work will go to the pump. After the crack is filled uniformly, you can remove the bridge.

The polymer hardens even in the sun. And to speed up the process, use the ultraviolet lamp.

After everything hardens, you can move to grinding and polishing windshield.

If you are interested in how damaged windshields are repaired, here is a detailed learning video, about the technology of their repair.

Auto owners in 99% of cases face the problem - cracks and chips on the windshield. Defects may appear in the results of numerous external factors, from stone to an accident. In this article, it is described, how and why troubleshoot damage. Also in the material presents the main methods and instructions, including the repair with their own hands using special sets for the recovery of car rates.

Let's start with the types of damage:

Why close chips and cracks?

4 reasons to close chips and cracks in the windshield of the car:

• Danger for the driver's life. If on the windshield, the strength of the structure decreases. So, with subsequent damage to the glass, the likelihood of breakdowns is large. Often such breakdowns lead to injury. Impairment of visibility, reducing the angle of review.
• Reducing the cost of the car. Buyers pay attention to cosmetic defects when buying a car. If you do not pay attention to the elimination of cracks or chips, the cost will fall in despite the technical condition.
• Remove the crack or chip cheaper than replacing the auto glass.
• In Guest 2018, it is written that the crack on the windshield should not be longer than 15.7 cm. In addition, a car is not allowed to operate with damage near windshield wipers.

How to remove the crack on the windshield?

There are several types of chipping and cracks of windshield. But they are eliminated by one principle. The ultimate point of repair of glass is to make damage to imperceptible retaining glass strength.

1. As soon as you notice the crack in the windshield, creep it with scotch, so that the dirt did not get there.

1. A hole is done next to the damage to reduce the load on the problem area. The crack is cleaned, then the air roll out from it.

1. Then transparent polymer materials are poured into place of damage. After the repair of cracks and windshield chips are invisible because the mixture is refracting as well as glass.

1. To remove the windshield defect you can buy tools and repair yourself, but you can contact the car service.
2. If the repair of cracks and windshield chips take place in the car service, then the light of the ultraviolet lamp is sent to the place of damage to the windshield, under the mixture that frozen themselves during 12-24 hours.

When should you change, and when to repair the glass?

Changing the glass is needed in 3 cases:

1. Damage pass through the edge of the glass. When the edge is damaged, the durability of windshield is disturbed. Repair such cracks meaningless, as such cracks will go further. If such a glass is raised again at an accident, it strongly hurts the driver and passengers.

1. Cracks in the heating zone are not subject to repair. Due to the temperature drops in winter, the glass can burst. Therefore, with such damage it must be changed.

1. When the damaged area is a third of the glass, trying to repair it does not make sense. It will be more expensive than putting a new glass.

It's important to know:

In accordance with GOST, any chips and cracks are subject to repair, which do not exceed 15.7 cm. You can repair larger damage, but after that cracks remain noticeable, so it is not a fact that you will pass inspection.

Any chips on the windshield are subject to repair and are not regulated by GOST.

Independently repair or donate in the car service? Pros and cons

Replacing and repairing windshield in Car service

Car services provide services to eliminate damage to windshield of different complexity.

When long cracks and numerous chips arise, you must contact the car service. Attempts to be repaired independently in such cases no sense. This is aimless time spent.

Attention:

If you try to dress a long crack yourself, you can harm and car and yourself. Glass in which the cracks are not correctly covered during a ride. Airbags here will not save.

The service masters professionals will make a job for 1 to 2 days. In 50% of car services, customers take the car 2-3 hours after they gave themselves.

Front windshield repair price in car service

The price of repair in the car service fluctuates from 300 rubles to 5-7 thousand rubles. However, the high price of work is associated with expensive car models. As a rule, the cost in the car service is comparable with buying a set or tools for repairing windshield.

Some car dealers have the price of fixing the centimeter of the crack. In them, the ultimate cost of work is considered based on the damage length.

With self-repairing, the price will depend on the cost of instruments and materials.

Note:

If there are insignificant damages, it makes sense to buy tools or a special set and repair yourself. Polymer mixture to eliminate damage is enough for 2-4 applications. So save on subsequent repair.

Repair glass do it yourself

To independently restoring windshield restoration instruments:

1. The polymer to which the damaged area will be closed. You need to choose a material that quickly hardens and have the same refractive factor as glass.
2. Injector and bridge. We need to enter the adhesive mixture A in the chip. It is preferable to choose metal models. Plastic analogues are short-lived.
3. Pump to remove air from a damaged area. Sometimes used to introduce a pressure polymer.
4. Diamond drill. It is necessary that the drill is regulated by the speed of rotation. With the help of a drill, drill holes in the frontside to remove the voltage from it.
5. Scraiber. This is a fixture for stripping a damaged area from fragments.
6. Flashlight. For a careful inspection of damage for bubbles.

Or use ready-made self-repair options.

The process of self-repairing windshield consists of the following steps:

• Cleaning the damaged area from dirt, fragments.
• Scratching. At this stage, a pass-through hole at a distance of 2 mm is drilled in the direction of the crack expansion. It will remove the stress from the glass and do not give damage to grow.
• Stripping crack scraper.
• Preparation of polymer composition for use.
• Preparation of the injector to use.
• Fill glue.
• Removing the injector from the windshield.
• Installing ultraviolet lamp (if available). The stage can be skipped, but to dry the car under the sunny rays.
• Polishing glass. It is recommended to use a polyrolol: drop it on a renovated chip and wipe the napkin for 5 minutes.

You can neglect the scraper and cleaning scraper when necessary to operate work.

What sets for self-repair are on the market?

Today the market presents many sets for self-restoration of windshield integrity. Among them there are both budget options and premium sets. Popular sets:

GlassProfi (Glassprof)

The kit is intended for self-elimination of chips to 30 mm. The set has a polymer, suction cup for fixing, syringe, adhesive disk and blade.

With the help of the adhesive disk and the sucker of the syringe is installed close to the damaged area. Through it is injected with a sticky material.

After the introduction of the polymer, you need to wait 3 to 4 hours. During this time, the composition hardens and the crack will become invisible. After this time, you need to handle glass acetone to remove the residues of the composition from its surface.

The cost of the kit is 1300 rubles.

In Windshield Repair Kit, a syringe is included, glue mix, protective films, adhesive disk, sucker - pedestal.

After applying the set, visibility is restored both on toned and on not tinted cars.

A sticky disk is installed on the place of damage, and the pedestal is mounted for a syringe. With the help of a syringe into damage, a polymer is introduced.

Note:

The kit works on a vacuum principle. At the time of filling with a polymer in a damaged area there is no air. The composition of the material is specifically designed to roll cracks.

The feature of the set is the speed of work. For this reason, it is suitable for urgent windshield repair on the road. 15-20 minutes after use, you can continue to move.

The set is suitable for eliminating such defects:

Set:

The set is designed for 2-3 applications. Prevents an increase in chip or crack. The goods received a lot of positive feedback.

Set price - up to 2000 rubles.

Example of eliminated damage using WindShield Repair Kit:

The kit has a similar principle of operation with the above. In it, the syringe, pedestal, adhesive disk and suction cup.

The difference from other sets is that the strength of its adhesive composition is 5 times higher than the strength of the glass.

Attention:

In the polymer there is acrylic acid. It is impossible to allow it to hit the skin and mucous membranes.

Using the composition in the summer, spend the repair in the shade, having cooled the "lobovukha" from the inside with a damp cloth.

In winter, on the contrary, it is better to heat the "lobovukha" before the fill of the mixture. In winter, on the contrary, you need to heat the windshield before the pouring of the polymer.

The price of Done Deal DD6584 - 600-800 rubles.

Permatex (Permatex)

Includes syringe, stand, sticky composition. The product is recommended to eliminate chips. Used to promptly repair damage on the road. Permatex is not suitable for filling cracks.

Skin repair is needed in sunny weather.

Attention:

The adhesive solution corps the paint on the car body. You need to cover the surface of the hood next to the windshield rag to prevent it.

After use, you need to not remove the syringe from the stand 30-40 minutes to give the composition to frozen.

The cost of the kit is 500 to 600 rubles.

In the set of a bottle with a polymer, suction cup, injector, a set of repair plates; scraper.

The seal must be carried out in the room. To make the glue hardened the car under the sun at the end of the repair.

The cost of the kit is 1200 - 1300 rubles.

Conclusion, conclusions and video

For prompt repair of windshield, it is preferable to use sets equipped with the necessary equipment. They are suitable to close damage on the road or in situations when not to get to the service.

However, to be confident that the glass is repaired qualitatively, it is better to contact the specialists. Today, car services perform such works per day, and the cost is comparable with the cost of buying a set.

The windshield is one of the most vulnerable parts of the car. All stones, bolts, minor items and all sorts of similar disgraces fly straight into it. Sometimes it is possible to get rid of only a scratch or lucky and the traces does not remain. But sometimes the angle of impact and the speed is so not successful that the chips or worse than the cracks remain. Cracks to restore independently quite difficult, but repair of chips on the windshield do it yourself It is quite possible.

Brief prehistory

I was driving on my Suzuki Jimny in the forest. He went on the track, dispersed and then the babes - the sound of the blow and as if something was cracked. I look attentively and see on the glass from the passenger side damage to the windshield. A small pothole or, as it is called, the church around which the cobweb of cracks went around in all directions. It should be noted, I repeated repeated that Suzuki Jimny windshield is subject to frequent damage, since the angle of glass is almost direct and all items do not slip, but pierce the lobovukha. But until now, I was lucky, and I, traveling for almost three years, caught only small pebbles, which were broken and only slightly scratched the windshield. But this time the damage was more global.

Of course, the first thought is to search for an approximate cost of replacing the glass in case the crack will begin to grow further. I figured at prices and was upset. Change the entire windshield due to one damage at such a price is quite considerably and meaningless.

Began to look for windshield repair options. The service set the cost of repair - 2000 rubles ... a considerable amount for repairs 1 cm china. Especially when taking into account that new Jimny glass can be bought for 2500 rubles.

Of course, it was decided to search for something about the repair of windshield with their own hands.

It turned out that the situation is not so catastrophic and the repair techniques already exist.. There is even special front windshield repair. There are decent videos about this question and some of the DRIVE are mentioned by its miraculous properties. But I did not come across a detailed article and that is why I decided that my material could be useful for the reader.

Damage to windshield

Damage to windshield are different.

A crack may appear, the through hole is formed, the chip appear, from which the crack will open. Of all these damages, we will consider only the chip.

So, before discussing the repair techniques, let's briefly study the chip.

Squares have long been systematized conditionally and divided into four groups: bullish eyes, star, moon and combined damage.

Most unpleasantly grabbing the latter.

Cases are different and repair is not always possible. But if damage "within", then, to bring the windshield into a normal form without replacement is quite possible.

Let me remind you that standard windshield consists of several glass layerswhich inside are punctured with a special polymer film. Usually it is three layers of glass. When the flying item falls into the glass, it damages not all layers. Skol is formed. The remaining layers can or crack, or remain intact. Using this knowledge is easy to guess what glass repair is based. A damaged part is dismantled or dried, and a special polymer material is applied to its place. But careful drilling is not always possible and it can not always be done without a garage and good lighting. At the same time, a certain dexterity of the hands is needed. Therefore, were invented sets for glass repair do it yourself. Drilling in this case is not required.

Repair efficiency will be directly dependent on the possibility of glue. Fill out disconnects in glass and microcracks.. Often, the damage looks in such a way that a small chip (2-3 mm) appears on the top layer of the glass, the glass groves grows on the second layer, and the inner layer remains integer. Such damage is treated worse than everything, as the glue will not be able to fully fill all the cracks of the crack. I caught just such a chip. But the repair still turned out to be effective and I am satisfied with the result.

The easiest way eliminate open chipswhere the upper layer is completely damaged. In this case, the glue will actively penetrate into all the space of damage.

Support for windshield repair It consists of a special beaten glue, a convenient syringe for injection of glue into a crack and auxiliary elements. On the Internet, it can be found called it called windshield Repair Kit.. This is the name of the set on Aliexpress and on Ali it costs 220 - 290 rubles. In Offline stores, where you do not have to wait for delivery, you can buy it for 390 - 400 rubles. In large network stores for sale "type version from the USA" for 800 rubles. At such a price, the meaning of buying a set remains in question. After all, the new glass for my car costs from 2500 to 4000 rubles. But here, of course, the costs of installation and extra headache should also be taken into account.

The principle of operation of this set is built on the fact that a special penetrating glue is introduced into the crack and chip, which, when frozen, forms a transparent layer and does not give the crack further. In addition to gluing, the glue probably also saves the edges of the chips and cracks, because after repairing the cracks as if he is healing. Drying occurs in ultraviolet and under vacuum conditions. The glue freezes precisely inside the crack without oxygen. It is for this that there is a special pedestal and double-sided adhesion, which limit air access to the glued point. This allows you to get a vacuum at the place of applying glue.

Windshield repair technology do it yourself

So, let's go. As a repair kit We use the classic Chinese Windshield Repair Kit.

• You have a shot on the track. Will be rationally to stay in a convenient place, go out, shine and stick fresh damage to scotch. Well, if the scotch is at hand. Need to try prevent dirt getting into place of damage. Essently, if water is driving in the internally damage space.
• Diva to convenient to repair the place. Give the magnificent Saving Windshield Repair Kit. We do it at such a time of day, so that with the final drying of the adhesive was still light. It is ultraviolet light important, not just lighting from the lanterns. Otherwise, the glue will not dry and turn into snot. Socks are then not to pull out of the crack. By the way, use an ultraviolet lamp nobody forbids. But the ambient temperature in this case is not so critical as it usually happens in the case of the painting nitroemal. I carried out repair at -5.
• First thing dry rag without fibers need to clear the place of the chip On the windshield. If necessary, this place must be carefully dried. It is useful to warm the glass blowing from the inside. Anyway, a higher temperature affects positively. Chemicals and liquids are better not to use. It is important to clear the chick, and not to smear the new dirt there, the fibers and do not form some film from the cleaner there.
• Now take a needle or thin sequel and thoroughly clean the place of the chick. It is necessary to do it very and very carefully. It is important not to delete glass. But the place of damage must be cleaned as much as possible from fragments. Let me remind you that the quality of repair directly depends on the ability of glue to get into the crack. Therefore, you need to try to maximize the channels of cracks.
• Next, take a pedestal and take it on the glass exactly as described in the instructions. Tail at 12 o'clock. Filled podium glue. It is necessary to fill it almost completely, leaving about ¼ free space.
• We pump the syringe from the kit and create a vacuum by fixing the piston of the syringe with a wire with a wire at the desired point.

• We offer 10-15 minutes. We make the movement of the piston of the syringe back and forth to increase the vacuum. Pre-press the syringe to increase the pressure. We carefully observe tightness. We repeat such actions 2-3 times every 10 minutes. When repetitions sometimes remove the syringe and check that there is no lack of glue inside the chip. If a lack is seen, then a pin of another polymer. You need to wait until all the bubbles from the processed space will be lost. They are clearly seen from the salon.
• After all these procedures, we remove the pedestal from the glass. We drip on the empty space in the chip glue, cover the film from the kit and smoothed under the level of glass. We are waiting for another 20-30 minutes until the glue is grabbed. After that, we remove the film and wash the blades of the remnants of unnecessary glue around the damage.

Relief repair result

Despite the seeming simplicity, the method is quite efficient. In my case, it was possible to cure almost 2/3 damage and turn down the top layer. In simpler cases, you can remove almost 4/5 chips. The glue itself cures quite efficiently, has good optical transparency. The cobweb of cracks almost completely disappears. Crater is poured by a polymer.

Repair of chips on the windshield with their own hands is a good alternative to an expensive procedure in the service. Of course, it will not be possible to get a new glass (and not with your own hands or in service). But it is quite realistic to extend the life of the glass installed. The visual effect is very decent. True, once again, I will not see the miracle. There will be a trace, and the appearance will not be the same. But for 200-300 rubles it will work out to significantly improve the situation.

In my case, it turned out about the same way as in the photo and I am satisfied with the result.

Compare in mode before / after

P.S. By the way, the whole chip in this miracle glue. Surely if you know its composition, you can buy analogue cheaper. After all, there is only 15 drops of glue in a set or even less.
