Car owners in 99% of cases are faced with a problem - cracks and chips on windshield. Defects may appear as a result of numerous external factors, from a stone to an accident. This article explains how and why to repair damage. The material also presents the main methods and instructions, including do-it-yourself repairs using special kits for auto glass restoration.
Let's start with the types of damage:
Why repair chips and cracks?
4 reasons to repair chips and cracks in the windshield of a car:
- Danger to the life of the driver. If on frontal crack, the strength of the structure is reduced. This means that in case of subsequent damage to the glass, the probability of breakage is high. Often these breakdowns lead to injury. Decreased visibility, reduced viewing angle.
- Decreased car cost. 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 despite the technical condition.
- Repairing a crack or chip is cheaper than replacing windshield.
- In GOST 2018, it is written that a crack on the windshield should not be longer than 15.7 cm. In addition, a car with damage near the windshield wipers is not allowed for operation.
How to fix a crack in a windshield?
There are several types of windshield chips and cracks. But they are eliminated on the same principle. The ultimate goal of glass repair is to make the damage invisible while maintaining the strength of the glass.
- As soon as you notice a crack in your windshield, cover it with duct tape to keep dirt out.
- A hole is made next to the damage to reduce the load on the problem area. The crack is cleaned, then the air is pumped out of it.
- Then, transparent polymeric materials are poured into the place of damage. After repair, cracks and chips in the windshield are invisible because the mixture is refracted in the same way as glass.
- To remove a windshield defect, you can buy tools and carry out repairs yourself, or you can contact a car service.
- If the repair of cracks and chips of the windshield takes place in a car service, then the light of an ultraviolet lamp is directed to the place of damage to the windshield, under mixtures that harden themselves within 12-24 hours.
When should glass be replaced and when should it be repaired?
You need to change glass in 3 cases:
- Damage extends over the edge of the glass. When an edge is damaged, the strength of the windshield is compromised. It is pointless to repair such cracks, as such cracks will go further. If such glass is damaged again in an accident, it will greatly harm the driver and passengers.
- Cracks in the heating zone cannot be repaired. Due to temperature changes in winter, the glass can burst. Therefore, with such damage, it must be changed.
- When the damaged area is a third of the glass, there is no point in trying to repair it. It will be more expensive than installing new glass.
It is important to know:
In accordance with GOST, any chips and cracks that do not exceed 15.7 cm are subject to repair. You can repair larger damage, but after that the cracks remain noticeable, so it’s not a fact that you will pass the inspection.
Any chips on the windshield are repairable and are not regulated by GOST.

Windshield replacement and repair in a car service
Car services provide services to eliminate damage to the windshield of varying complexity.
When long cracks and numerous chips appear, you need to contact a car service. There is no point in trying to repair it yourself in such cases. It's wasted time.
Attention:
If you try to repair a long crack yourself, you can harm both the car and yourself. Glass that is not properly sealed will crack while driving. Airbags won't help here.
In the service, professional masters will do the work in 1 - 2 days. In 50% of car services, customers pick up the car 2-3 hours after they gave it to the master.
car windshield repair cost
The price of repairs in a car service ranges from 300 rubles to 5-7 thousand rubles. However, the high price of the work is associated with expensive models cars. As a rule, the cost in a car service is comparable to buying a kit or tools for windshield repair.
Some car dealerships set the price of fixing a centimeter of a crack. In them, the final cost of work is calculated based on the length of the damage.
With self-repair, the price will depend on the cost of tools and materials.
Note:
If the damage is minor, it makes sense to buy tools or special set and repair yourself. The polymer mixture for repairing damage is enough for 2-4 applications. This saves you money on future repairs.
DIY glass repair
For an independent windshield restoration procedure, the following tools are needed:
- Polymer, which will close up the damaged area. You need to choose a material that hardens quickly and has the same refractive index as glass.
- Injector and bridge. Needed to enter the adhesive mixture and chipped. It is preferable to choose models made of metal. Plastic counterparts are short-lived.
- Pump to remove air from the damaged area. Sometimes used to inject polymer under pressure.
- Diamond drill. It is necessary that the speed of rotation of the drill be regulated. Using a drill, holes are drilled in the windshield to relieve stress from it.
- Scriber. This is a device for cleaning the damaged area from fragments.
- Flashlight. For a close inspection of the damage for the presence of bubbles.
Or use ready-made kits for self repair.
The windshield repair process consists of the following steps:
- Cleaning the damaged area from dirt, splinters.
- Drilling. At this stage, a through hole is drilled in the direction of crack expansion at a distance of 2 mm. This will take the stress off the glass and prevent the damage from growing.
- Cleaning a crack with a scriber.
- Preparation of the polymer composition for use.
- Preparing the injector for use.
- Glue pour.
- Removing the injector from the windshield.
- Installation of an ultraviolet lamp (if any). You can skip this step and dry the car in the sun.
- Glass polishing. It is recommended to use polish: drop it on the repaired chip and wipe it with a napkin for 5 minutes.
Drilling and cleaning with a scriber can be neglected if it is necessary to quickly carry out work.

Remember that defects on the windshield not only worsen appearance your vehicle, but may also cause an accident. Don't put off windshield repair!
We eliminate scratches
The main reason for the appearance small scratches on the glass is ordinary sand. It settles on glass, wiper rubber bands, seals and on a rag that you wipe your car with. Sand particles constantly scratch the surface. Therefore, visibility decreases over time. Polishing will help restore transparency to the windshield. Sanding is not recommended. Most likely, it will not be possible to carry out such processing independently.
For polishing the windshield, you can use folk remedies and professional materials. Before you start repairing scratches, wash your windshield thoroughly. Wipe it with a dry, clean cloth or a special glass cloth. Don't use newspaper.
GOI paste will help get rid of small defects on glass
To eliminate small scratches with improvised means, use toothpaste or GOI paste. best effect achieved using GOI paste. A small portion of the paste is applied to a clean cotton swab or a piece of felt. Then in a circular motion rub in the problem area.
Windshield polishing helps eliminate small, superficial scratches
Reapply the paste and rub in circles in the opposite direction. To speed up the process, you can use a grinder with a felt nozzle.
For polishing windshields in stores with automotive products Various kinds of polishes are offered. Before using pastes, we recommend doing a trial polishing on a small area of glass. The composition of polishes includes various kinds of reagents and it is not known how they will act on the glass surface.
Wash the glass thoroughly after polishing.
Removing deeper scratches is difficult. In this case, there are two options: you must come to terms with this state of affairs, or act drastically and replace the windshield.

It is not always possible to buy original glasses and you will have to install Chinese fake Low quality.
What to do if a chip or crack appears on the glass:
- Immediately seal the damage with transparent tape. Operational actions will allow achieving 80% transparency of glass after repair operations. Scotch tape or sticky tape protect the damaged area from contamination.
- Wiper blades should only be used when absolutely necessary (rain or snow). A crack or chip can become clogged with small debris that is problematic to remove. Difficulty and reduce the quality of repairs.
- Before removing a chip or crack, do not wipe the damaged area manually with a wet or dry rag. Microcracks are quickly clogged with dust.
- Minimize the use of heating or blowing front glass. The temperature difference between inside and outside the machine can cause an increase in the size of a crack or chip.
- Experts recommend not to delay the repair of damage to the windshield. The optimal time should not exceed 3-4 days. Delaying recovery operations reduces the chances of a quality job.

- chip repair from 150 rubles. for 1 mm. damage in diameter;
- crack repair from 100 rubles. for 1 cm damage;
- repair of an internal crack from 150 rubles. for 1 cm damage;
- stop crack 500 rubles.
For all work, experts provide a guarantee. It's much cheaper than buying and installing a new windshield.
What does a specialist do with a chip or crack?
- A careful inspection of the damage and a conclusion about the possibility or impossibility of repair.
- Glass washing. Thorough removal of dust and dirt.
- Usage special liquid to dislodge contaminants from microcracks.
- Drying and degreasing the repair area.
- At the edges of the cracks, small holes are drilled to prevent further increase in size.
- Air is removed from cracks and chips with the help of special equipment.
- Bridge and injector installation. The nozzle is placed over the drilled hole. A special polymer repair compound is poured. The piston moves into the injector cylinder.
- An ultraviolet lamp is used to accelerate the curing of the polymer material. On average, 5 minutes is enough to gain strength. The repair site is polished.
- A chip without cracks is filled with a special repair compound. Drilling is not performed. After applying the polymer, the place of repair is closed with a film. Again, an ultraviolet lamp is used to enhance the strength of the composition. The place of repair is being polished.
It is impossible to independently repair cracks and chips on the windshield without special equipment and materials. It is better to turn to professionals, otherwise amateur performance will lead to a complete glass replacement.

Features of car glass repair
The formation of scratches and chips is mainly caused by mechanical damage resulting from the ingress of stones or pieces of ice from under the wheels of other vehicles. Vehicle. Many car owners are in no hurry to remove cracks, scratches and chips on the windshield, especially if they are located closer to the edge and do not interfere with the view. In this case, any damage tends to gradually expand. Over time, any minor scratch can cause the glass to become unusable and need to be replaced. Therefore, we recommend that you repair chips and cracks on your windshield as soon as possible.
Car glass repair is desirable to be carried out immediately after receiving mechanical damage. This will save a lot of time and financial resources. If you notice a chip, you should take measures to prevent its development:
- cover the damage with a small paper strip;
- seal with tape to ensure protection from contamination;
- do not turn on the heating and do not direct the stove blower to the windshield;
- try to ensure smooth movement without strong vibrations of the car.
The sooner you start repairing your windshield chips and cracks, the less expensive the procedure will be. For getting best results should be taken to a specialized workshop. Employees technical center"Autoscratch" carry out the restoration of the windshield of a car according to a pre-formed effective technology, using high-quality Consumables And modern equipment. First of all, experts determine the type of defect. There are several main types of damage.
- Grout - formed as a result of the hard impact of worn wiper blades, can be eliminated by polishing.
- Scratch - slight damage to the outer layer of glass. Can be removed with polishing.
- Chipped - minor damage up to 1 mm deep without through penetration of the outer layer. Car glass repair this case not required.
- Skol - serious defect, as a result of which the outer layer of glass breaks through. May have various forms(vortex, "bull's eye", "asterisk", etc.), requires urgent repair of car windows.
- A crack is a damage that causes a layer of glass to separate into two parts. Often formed from small chips, needs repair. Large cracks lead to the need to replace the windshield.
Glass repair tools
After a preliminary inspection of the damage and determining the type of defect, the master proceeds with the repair work. The procedure for removing chips and scratches on a car glass includes several successive steps:
Repair of chips and scratches on the side and windshields of a car is much cheaper than replacement, and requires less time. The procedure allows you to restore the characteristics of the material, as well as prevent the expansion of damage without harming performance characteristics car.
Auto glass repair
Before carrying out operations, the degree of damage should be assessed: if you do not have sufficient experience, it is risky to take on the removal of complex combined defects. To repair a chip or crack in the windshield, you must have a number of special tools and materials available. For work you need:
- air compressor;
- injector;
- polymer composition;
- polish;
- drill with small drills;
- UV emitter.
The refractive index and degree of transparency of the polymer must be exactly the same as that of the original glass, otherwise the restored area will be very noticeable visually. Before repairing cracks in a car glass, clean the damage from dirt. For this, it is not recommended to use chemical detergents, as they prevent the adhesive from bonding to the surface. Complete drying of the polymer occurs within 7-8 hours.
On the net you can find a lot of manuals for repairing cracks in the windshield, but the most competent solution would be to contact the workshop. Specialists have professional equipment and guarantee neat execution all necessary operations, eliminating the risk of irreparable damage.
How to order car windshield restoration?

Anything happens on the road. A fairly common situation is when all sorts of chips and cracks appear on the windshield. There are many reasons for their appearance: the main one is stones bouncing off the wheels of oncoming cars, since we have a lot of gravel roads. In addition, the cause may be fallen objects, and even the actions of hooligans. And if you find a chip or crack on the windshield, without wasting time, you should start replacing the windshield, or repairing it, because driving with a damaged windshield is not recommended, and there are several reasons for this.
1. A damaged windshield distracts the driver from the road and obstructs visibility.
2. Cracks, subsequently, tend to grow, which leads to future scattering of the windshield.
3. And the most basic reason is that a damaged windshield is a major hindrance if it's time to technical inspection car.
If you suddenly find 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 at a car service. It will cost you much less, because it is not enough to buy it, installation also costs a lot of money. In addition, a replaced windshield is a major stumbling block when selling a car. You can’t prove to the buyer why you replaced it, if there was an accident?
If you find a small crack or chip on your windshield, the first thing to do is seal the damaged area with a special vinyl film, or with ordinary transparent tape. This will protect the damaged area from getting dirt inside the crack, as if dust or dirt gets into the cracks, this will seriously increase the cost of repairs. It also happens that in a car service they do not restore windshields at all, in the cracks of which dirt has got.
If, however, repairs cannot be made immediately after the formation of damage, do not wash the glass with chemical detergents. They will not allow the glue to polymerize properly.
Damaged windshield is repaired by pouring special polymers into chips and cracks. These polymers have very good optical properties, which, in transparency, are in no way inferior to ordinary glass. Also, such polymers have good shock resistance.
An important factor is to choose the right car service for the work. After all, the prices for work, in each individual car repair shop, can vary significantly. Therefore, before starting the repair, show the "front of work" to the auto mechanic so that he immediately tells you how much the repair will cost you.
If on this moment, financial problems do not allow you to immediately start repairing the windshield, then you can ask the master, temporarily, just drill a hole. So, you will prevent further crack growth, besides, this is an inexpensive operation. This way, you can save money when a serious repair begins.
By the way, do-it-yourself repair of chips and cracks is quite acceptable, because car services do not always take on such work, it is easier for them to change the windshield completely. And if you fully follow the repair technology, you can easily do everything yourself, since the necessary materials are sold everywhere.
Two holes are drilled along the edges of the crack so that it does not go further. Equipment and materials for windshield repair.
So, let's list what is needed in order to fix a chip or crack on the windshield with your own hands.
- Adhesive polymer to seal cracks. When buying, you need to remember that its hardening time should be small. As for transparency, each product has its own transparency coefficient, and it must correspond to the glass index.
- Electric drill, which can relieve stress from the glass. That is, drill holes along the edges of the crack so that it does not grow. The drill must be taken diamond.
- Bridge and injector. They inject glue into the crack. They are disposable (plastic) and reusable (metal).
- Pump. They remove air from damaged area.
- scriber. Needed to clean the area around the damage.
- electric flashlight, to refine the boundaries of the crack, and to detect bubbles in the adhesive.
- To speed up the drying process of the polymer, it is useful UV lamp.
Well, in order to clean surfaces, prepare cleaning fluid and wipes.
How to remove chips and cracks on the windshield?
The work area must be thoroughly rinsed and dried, because the remaining moisture and dirt will not allow the glue to properly fill the damage. Thoroughly clean the crack, use a blade to remove fragments and small debris. After that, blow the damaged area with a compressor or pump, and you can get to work. And try not to get direct sunlight on the glass.
After preparing the surface, an adhesive polymer is applied to the crack. The first step is to “relieve stress” from the damaged area so that the crack does not grow even more during the work. For this, along the edges of the crack, drill through hole, at a distance of 2 mm in the direction of extension. Then, with a little effort, bring the crack to these holes.
Set the bridge with the injector so that the goose is directly above the desired location.
Slowly feed the adhesive polymer into the crack. Get spare glue. Removing excess polymer is easy, but if it is not enough, the work will go down the drain. After the crack is filled evenly, you can remove the bridge.
The polymer hardens for a very long time even in the sun. And to speed up the process, use an ultraviolet lamp.
After everything hardens, you can proceed to grinding and polishing the windshield.
