I often drive on very bad roads in the Tver region. Sometimes the administration tries to make patching by filling the pit with a mixture of rubble and something that looks like tar. From such a "patch" a pebble flew into my windshield, and later another one. As a result, I came from the dacha with two chips on the windshield. One of them was deep, the other was shallow, but had two cracks. To prevent cracks from spreading all over the windshield, my husband bought a Permatex glass repair kit.
The package contains a syringe with a one-component adhesive, thick film and instructions. This compound polymerizes in bright daylight within a few seconds. If the weather is not sunny, then you will have to use an ultraviolet lamp.
3. Insert the syringe into the suction cup and fill the glass with polymer.
4. After filling the chip area with polymer, put a thick film on top and let the substance harden. The instructions say wait a few seconds, but I held it for twenty minutes.
The deep cleavage was healed. You can't even see it from the outside, you can only see it from the inside. Another chip that gave the ramifications will have to be repaired by professionals. A lot of polymer will be needed, and I'm afraid to spoil it.
The windshield was repaired two and a half weeks ago. The substance is in place, the cracks have not gone.
Nowadays, there are various proposals on the market to protect glass from damage. One of the most popular options is a protective film sticker on the glass, which protects an expensive part from damage, and many car owners prefer not to wait for the next stone in the glass with subsequent repair or replacement of this glass.
But what about the situation if the windshield of the car was nevertheless damaged, and small cracks and chips have already appeared on it? Go to a car service for an expensive repair or try to fix this problem yourself?
If you decide to repair cracks on the windshield with your own hands, we will tell you what materials and tools you need and how to do it according to all the rules.
To begin with, we will determine what minor damage can be easily and simply repaired on our own, without replacing the windshield.
So, in order to independently repair cracks on the glass, you need to prepare the following set:
Having prepared the necessary set of materials and tools, we proceed to the repair.
If you want to get a high result of windshield repair, we recommend that you take this process with the utmost seriousness and scrupulousness. Read also how to fix cracks in the bumper.
What to do if a chip appears on the windshield? Try to repair the glass as quickly as possible, because due to vibrations and temperature changes, even a small chip can turn into a large crack. You can remove a crack or chip on the windshield at a service station or using a special kit.
You can buy a special set at a price of 300 rubles. It should include: a syringe with a repair compound, an applicator for filling in chips and rings with a sticky surface for installing the applicator on the glass. Additionally required: blade and food film. Using the kit, you can repair a crack in the windshield up to 20 cm in length.
The windshield must be clean, dry and cool (not exposed to sunlight).

The windshield must be clean, dry and cool (not exposed to sunlight).
Procedure :
Place the syringe firmly on the edge of the crack.
Squeeze out the repair compound by moving the syringe (from the end of the crack to the beginning) slowly and smoothly along the crack. In order for the repair compound to completely fill the crack, lightly press on the glass under the crack.
Cover the crack with cling film.
Put the car in the sun for 20 minutes to polymerize the composition (on a cloudy day for 1 hour).
To stop the crack in the windshield, you will need to drill the glass, for this, seek the help of specialists. If the number of cracks on the glass is large and they cannot be repaired, then the windshield should be replaced (instructions).
If the crack is in the driver's line of sight, then such vehicle operation will not be safe. By the way, do you know which washer nozzles do their job better?
The injector and fitting of the "WINDSHIELD REPAIR KIT" were cut off, according to the instructions, after 5 hours. There was a yellowish viscous resinous substance in the damage, which did not penetrate into thin rays (within five days, this composition did not acquire transparency, and did not harden).
5. Result and comments of sellers of these formulations In one of the companies presenting the WINDSHIELD REPAIR KIT BULLSEYE composition to the Russian market, we were told that this glue hardens “in the absence of its contact with oxygen, that is, by an anaerobic reaction”. That is why it hardens well in thin rays of chips, and in large potholes and on the surface it will remain liquid! In addition, we were informed that the purpose of this kit is not to repair chips, but to stop the crack. Unfortunately, when asked what has the “bull's eye” chip mentioned in the title, we did not receive it. In another Moscow trading company, which represents the interests of several firms, including ABRO, they answered our questions simply: “We only trade, all questions and complaints to manufacturers.”
We concluded that all the reviews we read on the Runet were written by the sellers themselves (((((, for which there is only one concept - sell and forget ((((
With this test, we would like to warn motorists against self-restoring auto glass.
Once, returning home in the evening, I received a pebble from under the wheels of an oncoming car. A chip formed on the glass, I decided to fix it myself and was ordered Permatex 16067.
Mazda 3 2008, petrol engine 1.6 l., 105 hp sec., front-wheel drive, manual transmission - DIY repair
And I have such a chip for 1500 rubles. They also repaired it. There is a point left. Two years have passed, there are no cracks. Glass China! Although they are professionally repaired more efficiently! There won't even be a dot. I saw the result of work, a professional friend! And for money, you still can't get a better result than yours! Based on my experience! The whole glass costs 3500! And then how much -1500!
If the glass is cracked or chipped, it must be repaired as soon as possible. Self-repair of auto glass is a rather complicated procedure that requires special tools and materials. For beginners in this difficult task, it is recommended to start by eliminating minor damage. Large and complex cracks are often not repaired even by specialists. The glasses are simply replaced with new ones.
As soon as damage is detected on the glass of the car, appropriate measures must be taken immediately so that later this damage can be easier to repair.
Place a crack or chip with several layers of paper and tape it so that the tape covers the entire surface of the paper. This is necessary in order to prevent the penetration of dust and moisture into the damage cavity and to facilitate the repair of the car glass with your own hands.
Instead of trying to properly repair the crack, do not try to rub the crack with glue, or wash and rub the damaged area. Because of this, a web of small cracks can form, and because of the glue that has filled the entire cleavage space, it will be impossible to perform high-quality repairs.
If you need to drive a car with damaged glass, you need to do it smoothly, avoiding all irregularities. Excessive shaking will increase the crack.
Strong temperature changes contribute to the growth of damage.
Therefore, do not turn on the stove or air conditioner at full power. Try to use less windshield wipers and washers.
Do not postpone car glass repair indefinitely. Minor damages are repaired easier, faster and better.
Optical glue is needed from materials.It is a special liquid polymer, colorless and completely transparent after solidification. There are one-component and two-component adhesives. In the latter version, the polymer consists of 2 parts, which must be mixed according to the instructions before use.
When choosing an optical adhesive, pay attention to its density. For small chips and cracks, it needs high penetrating power and low density. Repair of auto glass with large open damage requires a polymer with high strength and high density.
An important indicator of optical glue is the transparency coefficient. You must also pay attention to it, it must correspond to the transparency of the auto glass being repaired. The transparency coefficient of auto glass is specified in the operating instructions or in the repair manual. In extreme cases, you can find it on the official website of the automaker.
Check in advance the polymerization time of the composition.
For convenience, this time should not exceed 24 hours. Ask the manufacturer of the composition. For example, the repair of automotive glass with materials made in the United States often does not withstand domestic climatic conditions. Be sure to check the expiration date of your optical glue.
Try not to skimp on the polymer composition. Never try to repair car glass with liquid glass or sealant. It is impossible to achieve even satisfactory results with such materials, and after their use, the glass can simply be thrown away. It will not give in to alteration.
Of the auxiliary materials, cleaning agents for auto glass are required: napkins, rags, cleaning fluids, degreasing solvents. You also need special blades to remove excess glue.
Of the tools, the first thing you need is a bridge with an injector. It is necessary to fill the cleavage space with optical glue. Both plastic and metal bridges are commercially available. Plastic ones are much cheaper, metal ones give a higher quality of car glass repair. Steel models can be reused, while plastic ones are intended for single use only.
For glasses with a strong bend, you need to purchase bridges with three supports, for flat and slightly curved ones - with two legs. Suction cups on supports can be pump, lever-vacuum or conventional. Each of them is good in its own way: the pump pump is more convenient on vertical surfaces, the lever-vacuum one gives equally good results anywhere in the glass, ordinary suction cups allow you to fill long cracks by sliding the bridge along the damage.
A drill with a diamond drill should drill in modes from 5 to 10 thousand revolutions per minute and smoothly adjust the rotational speed within these limits.
For the convenience of work, you need not an ordinary drill, but a micro drill with the ability to connect to the vehicle's 12 V on-board network.
The pump for removing air from the damage cavity is a scriber. In addition to its main function, it is used to cleanse the repair site from the smallest particles of glass and dirt, to create additional chips in order to relieve stress in the area of the main damage or in the places of drilling.
VIDEO
Professionals prefer to use steel automatic parting pumps with a special spring device to create additional chips. Their main advantage is the precisely calculated impact force when creating a chip, which is guaranteed to create this chip, but at the same time will not lead to the formation of a crack on the entire surface of the auto glass.
The UV lamp accelerates the curing (polymerization) process of the optical adhesive.
This is a useful but optional tool. The peculiarity of the lamp is that its efficiency does not depend on the power of the lamp, but on the type of bulb used and the characteristics of the polymer itself.
All automotive glass is divided into 2 categories: triplex and stalinite. Triplex glass is relatively easy to repair. As a rule, they are installed as a windshield, sometimes as a rear, rarely as side ones.
Glasses of the Stalinite type are very hard, but at the same time they are quite fragile. It is difficult even for professionals to repair them, since with any careless handling they crumble to pieces. Most often, stalinite can be found on the side windows of a car, sometimes on the rear window. The windshield of the Stalinite type has not been used since the 50s - 60s of the twentieth century.
It is possible to independently repair glass chips with rays up to 3 cm and linear cracks up to 15–20 cm long. More extensive damage is within the power of specialists in their field. Specialized centers do not always undertake such work, or provide a limited warranty for their work. Especially in cases where a car windshield repair is required at its lower edge.
The basic rule when self-repairing damage is to try to eliminate them at an early stage, without waiting for a small chip or scratch to turn into large cracks.
It is better to entrust large damage to professionals or replace the glass completely with a new one.
Do-it-yourself auto glass repair begins with the preparatory stage. On it, the glass being repaired must be thoroughly cleaned, degreased and dried. In this case, it is better to use cleaning agents to a minimum and press on the glass. This can exacerbate the damage.
Usually, at the preparatory stage, they try not to wash the glass, since moisture can get into the space between the laminated glass layers, and it will become impossible to dry it. But if the chip or crack is heavily soiled, there is no alternative to washing.
When repairing a chip, it is recommended to carefully clean it with a diamond drill, and then blow the resulting cavity with a strong stream of air. A compressor, pump, or household vacuum cleaner can be used to create airflow.
Residues of dust and glass are removed directly from the damage cavity with a special pump - a scriber.
After the completion of the preparatory work, the injector is installed on the repaired place so that it is located exactly opposite the center of the cleavage. Use a tape measure, ruler, or laser distance meter to get the accuracy you want. With the help of adjusting screws, the injector is set strictly parallel to the surface of the auto glass.
The polymer is mixed (if using a two-part adhesive) according to the instructions and injected into the injector using a syringe. The latter, in most cases, is sold complete with an injector. Then, using the injection piston, the material is injected under pressure into the damaged cavity. The piston is deepened until all air bubbles come out of the cleavage cavity. It is more convenient to control the presence of these bubbles with a powerful lamp or flashlight.
VIDEO
In cases where the chip is deep, the procedure for filling it with glue has to be repeated several times. It is recommended to calculate in advance the required amount of polymer and, just in case, introduce a little more of the composition.
After that, the injector is carefully removed, cleaned and washed. Excess polymer composition is carefully removed with a dry napkin.
As soon as the optical adhesive comes into contact with air, the polymer begins to solidify. Its curing time is indicated in the instructions for use. You can speed up the process with an ultraviolet lamp. During the polymerization of the glue, it is better to seal the repaired area with a finishing film so that dust or moisture does not get on the glue.
At the final stage, using a blade, the excess polymer is once again removed, and the glass itself is carefully polished.
The procedure for repairing a crack is more complicated in comparison with the process of sealing a chip. First of all, the glass is also cleaned, degreased, dried and blown with air.
The area around the crack is scrubbed.
At the second stage of the repair, stress is relieved along the crack. For this, holes are drilled with a diamond drill at a distance of 1–2, but not more than 5 mm from the edge of the cracks. The distance between the holes should be 30-50 mm. The depth of the holes should not exceed half the thickness of the auto glass itself, since the film is located in this place of the triplex. You need to drill the holes carefully, trying to expand the crack to the holes themselves, but so as not to accidentally drill through the glass.
With the help of an injector, the cavity of the crack (and the holes made) along the entire length is filled with optical glue. The injector is installed on the edge of the crack, and then sequentially rearranged along it. Injectors with conventional suction cups can be sliding to a new location, which significantly saves time and effort.
At the final stage of repairing a chip or crack, it is advisable to polish the repaired surface.
This will allow you to achieve up to 95% transparency when restoring the windshield with your own hands.
It should be remembered that polymer glue is a rather toxic material, therefore it is not recommended to inhale its vapors. In addition, it is necessary to protect the skin, eyes and car body from this adhesive.
Trouble can happen at any time: on the windshield, suddenly, you find a chip or crack. The most offensive thing is that you can foresee this situation, but you can hardly avoid it. The issue of a malfunction (chip, crack) of the windshield must be treated philosophically, and if this is not fatal damage, when, unambiguously, replacement of the autoglass is required, then there is a way out. Either you go to a car service, or do your own car glass repairs.
Car glass repair is a serious undertaking and requires your patience and understanding of the goal. Glaziers have different estimates of the length or area of damage to the glass of a car that can be repaired. At one of the forums, the figure of the total length of the repaired cracks on the windshield was even announced - 3 meters. This is a clear overkill, most likely the car was being prepared for sale. Not serious.
The simplest option is when the glass is simply overwritten. As a rule, this happens due to the incorrect installation of the "wipers". In this case, auto glass repair is not required, you just need to polish the glass.
The second option is a stone chip. Chipping is not a cause for particular concern, but you must try to eliminate it immediately. So that later, after a certain period of movement, it does not turn into a crack on the glass. Car glass repair with a chip will also require you to know the technology of car glass repair.
Well, the most unpleasant moment is the cracks on the glass. The cause of the crack may be a stone, a chip removed at the wrong time, a defect in the geometry of the car body, or poor-quality glass. Automotive glass repair technology will require certain materials, tools and desires from you. In principle, there is nothing difficult, but you will need attention and patience.
Important! If a crack appears on the glass while driving, follow a few rules:
Turn off the blowing of the windshield (if it is on) in order to eliminate the temperature difference.
Reduce speed to minimum to avoid strong body vibration.
When driving on rough terrain, choose a route so as to minimize the effect of "twisting" of the body.
Get to the place of deployment, determine the loss (size of cracks) and start repairing the glass of the car.

In order to carry out high-quality and efficient repair of auto glass, you will need a "repair minimum:
Optical adhesive (polymer). Initially liquid. Should have a transparency coefficient the same as that of glass. It is better to choose polymers with a short curing time. The technology of auto glass repair is thus improving.
Bridge and injector for introducing polymer into injury. It is better to purchase the bridge and injector from metal, because plastic are limited in terms of use. Although you are not going to repair auto glass every day.
Pump ... It is needed to remove air and sometimes to create pressure when the polymer is injected.
Drill ... Diamond drill. For drilling edge cracks. This relieves stress on the glass. Preferably with adjustable speed.
UV lamp ... To influence the polymer during solidification.
Liquids : cleaning and moisture-removing wipes - for surface treatment before glass repair.
Scriber - a tool for expanding damage and cleaning from small fragments.
Flashlight and mirror - to clarify the boundaries of glass damage, and to check for the presence of air bubbles in the polymer.
VIDEO
Let's look at the basic technique for repairing auto glass with our own hands. We will present the main stages of this painstaking event - auto glass repair.
Relieving stress. Drill glass a short distance from the visible edge of the crack. With a little effort we hammer the crack to the hole.
We clean, rinse, blow and dry the cavity.
Install the bridge with the injector, the gander over the original place of damage. We dilute the polymer (if it is two-component) and feed it to the crack.
After filling the chip with polymer, remove the bridge and injector
We direct the UV lamp to the place of repair for polymer hardening. Sunlight will increase the curing time by 3-4 times.
After complete hardening, we proceed to polishing the glass. Polishing will ensure the invisibility of the repair site by 75-90%.
That is actually what it is - the technology of repairing car glass with your own hands.

The windshield is the most vulnerable point of the car. From mechanical stress, vibration during movement, temperature changes, chips or cracks may appear on it. The glass will not break completely just because it consists of two glass sheets glued together with a special glue. But if the damage is not repaired, then after a while it can turn into a large crack, and the glass itself can crack into pieces. Therefore, as soon as possible, you need to repair the glass yourself or contact a special service for help.
Mechanical damage that appears on the glass of the car can be repaired only in the following cases:
the inner layer of the triplex is not damaged;
factory-made glass is used;
cracks are no more than 50 cm long and do not reach the edge of the auto glass;
notch, chipping or spall without cracks or with small outgoing cracks.
Recovery is impossible if the triplex is split into several parts, its central part is crumbled or covered with a network of cracks.
To understand the complexity of the repair to be performed, you should decide on the type of damage. They can take various forms and types:
cracks with rays from the point of impact;
cracks that form arcs or circles;
round chips;
cracks in the form of cobwebs;
defects from cracks and chips;
double-sided crack.
If only the outer layer of auto glass is damaged, then you can repair it yourself. If the inner and outer sides are damaged, the glass sheet will have to be dismantled. It is rather difficult to carry out such a procedure on your own.
To restore the triplex, you will need a special car set of tools, which can be purchased at the Inseif online store. The set should include:
blades for cleaning glass from polymer;
ultraviolet lamp;
injector;
injector rings and seals;
transparent plates;
scriber;
hand electric drill;
syringe;
polish;
various polymers for filling chips and cracks;
drills from carbide alloys.
The quality of the windshield repair largely depends on the preparatory work.First of all, the glass must be cleaned of dust and dirt, having previously sealed the damaged areas with tape so that moisture does not get into them.
Cleansing technology depends on the type of damage:
Round chips are cleaned with a carbide rod and wiped with a dry cloth.
Cracks in the form of rays are first processed with a drill. They need to be drilled out with a tapered drill. You should get a wide, but not deep cone. Drill carefully so as not to damage the inner layer.
A skyber is used to clean rounded cracks. If it was not possible to remove the dirt with this tool, then the damaged areas are reamed with a drill.
Cracks running in different directions are cleaned with a carbide rod or reamed with a drill. So that the length of the damage does not increase, you need to drill a conical chip, retreating 1-2 mm from its end. After that, the cracks are artificially brought to a chip by gently pressing on the glass with your hands.
Damage to the laminated glass is filled with a special polymer glue, the properties of which are close to those of auto glass. Before pouring the polymer, dust and small particles should be removed from the surface with a vacuum cleaner. Then everything is thoroughly wiped with a dry napkin. Filling is done with an injector.
Procedure for the procedure:
The injector is installed over the chip and is attached to the surface using suction cups. The equipment should be installed so that it completely covers the chip.
The injector cylinder is carefully screwed into the axle. The sealing rubber located on the tip must be in contact with the triplex surface. To prevent the glue from flowing through the O-ring, the cylinder is screwed strictly parallel to the surface.
6-8 drops of the selected polymer are instilled into the injector cylinder. The density of the polymer composition directly depends on the thickness of the cracks. For small cracks, a polymer with a low density is selected.
The injector piston is twisted into the cylinder until a slight pressure appears in it. Within a few minutes, the polymer will fill the damage, so no action is required during this time.
When the chips and cracks are filled, the piston is unscrewed and set to the top position. For about a minute, air will be pumped out of microcracks and a vacuum will be created. This procedure is performed several times. There should be no air bubbles in the damage.
When all defects are filled with a polymer composition, the bridge and injector can be removed. The equipment used can be cleaned with alcohol or acetone.
Defects are filled with polymer, but you can not use the car until the glue dries well ... You can quickly dry it using an ultraviolet lamp, after dropping PL-106 polymer onto the treated area and covering it with a special film from the kit. The film is smoothed out, and a lamp is installed over the windshield for 5-6 minutes.
When the surface dries, the lamp and the film are removed, and the treated areas are cleaned of excess glue. A blade is used for this, which must be held perpendicular to the triplex. The cleaned surface is wiped with a napkin and rubbed with a special polish.
After the repair, damage should not be noticeable. You can only see them if you look closely.
If the damage is small and there is no time to glue them thoroughly, you can use the tools at hand.
A new crack that appears on the triplex must be immediately closed from dust and dirt, so that it can be easily cleaned during repairs. You can use ordinary stationery tape, gluing the place of damage inside and outside with it.
A thin crack can be varnished with a colorless varnish to prevent damage from growing. The varnish is applied on both sides in a thin layer. It should dry well. Even the rains cannot wash off the varnish ... It can hold out on glass for several years.
Using these tools, you can prepare a composition that is suitable for repairing damage to the windshield. Recipe:
In a glass container, mix turpentine and acetone in a 1: 3 ratio.
Cut the styrofoam into small pieces and add them to the solution.
When the foam dissolves, it should be viscous and transparent.
The solution is mixed and chips or cracks are filled with a thin brush or syringe.
The adhesive hardens quickly, so it must be used immediately, applying to damage in small portions.
VIDEO
In any hardware store you can buy a silicone-based adhesive and apply it directly from a tube to damage. If the crack is thin, you can use a syringe. The cavities are filled with silicone slowly to avoid air entrapment. The glue can dry from 12 hours to a day. ... After that, it can be covered with clear varnish.
If you have a little experience and a special kit, you can repair the glass yourself with your own hands. However, if the damage is serious or you are in doubt about your ability, contact a car service that solders the windshield. There, with the help of special equipment, they will quickly be able to solder almost any chips and cracks. After such a renovation, the triplex will look like new.
Before we deal with the types of equipment for auto glass repair, we need to decide on technologies and terms. Modern cars are named.
The windshield of a car (in everyday life it is also often called "windshield" or "windshield") is one of the most vulnerable elements of a car. Kog.
Almost any scratches can be repaired with quality glass polishing wheels. Thanks to high-quality abrasives, they grind damaged.
Damage to the windshield when a stone enters it or the formation of cracks with a large temperature difference is quite common. In most cases, a complete windshield replacement is avoided. But you cannot do without repairs, since over time, even a small crack can completely destroy the glass.
The cost of repairing a windshield in a car service depends on the type of damage, its size, the repair materials used, and sometimes the region.
Estimated prices for repairs using Russian materials:
Chipped-chipping repair - from 500 rubles.
Repair of a chip up to 3 mm - from 1000 rubles.
Repair of a chip with rays up to 5 mm - from 1200 rubles.
Repair of a chip with rays up to 1 cm - from 1700 rubles.
Repair of a chip with a lost fragment - from 2200 rubles.
Crack repair (filling) - from 50 rubles / cm
When using imported repair compounds, the cost can increase by 30-100%.
An example of the cost of repairing chips in one of the salons in Moscow
Before repairing, we recommend that you independently call several glass repair companies, describe the situation and clarify the prices for repairs. To search for car glass repair shops, you can use the 2gis service.
You can repair the windshield yourself. If you have a certain set of equipment and follow a strict sequence of actions, you can make repairs at home, for example, in a garage. In some cases, the cost of a set of equipment and materials may come out less than the cost of repair in a car service. In addition, you will gain experience, and you can use the equipment and materials in subsequent glass repairs.
It should be remembered that it is advisable to carry out repairs almost immediately after glass damage. Otherwise, dust and dirt trapped in microcracks will significantly affect the quality of work, and removing them completely will be quite problematic.
1. Cleaning and degreasing of cracks and glass surfaces ... We need to remove dirt and grease from the crack.To do this, you can use ordinary household cleaners, special auto chemicals for cleaning glass, or just use alcohol. Particular attention should be paid directly to the site of damage. During cleaning, it is necessary to thoroughly blow out the crack, for this you can use a conventional pump.
2. Drilling a chip or crack ... This must be done in order to remove small pieces of glass and remaining dust from the crack, as well as to better fill the crack with the polymer composition. Using a drill or a drill with a small diameter diamond drill, a small hole is made in the center of the chip. In the event of a crack, the drill is drilled to relieve stress on its edges. After that, using a compressor or a hand pump, it is necessary to blow out glass chips and dust. If you don't have a drill or drill at hand, you can use an ordinary sharp blade.
After drilling the crack, you must repeat the first step of the instructions for the final cleaning of the crack / chip.
3. Filling the defect with a special polymer compound. For this, an injector and a bridge are used. Instead of a needle, the injector has a suction cup. The injector can be either reusable metal or inexpensive plastic. Correct installation of the injector is essential. It should be located in the center of the chip and strictly perpendicular to the surface of the windshield. Otherwise, a tight fit of the working part of the injector to the glass will not be ensured, which will not make it possible to create the required pressure. The desired tool position is achieved using the adjusting screw.
After that, it is necessary to fill the injector with a special polymer composition. First, the composition is drawn into a syringe - dispenser, and then with its help it is fed into the injector. After that, pressure is created on the injector and the adhesive fills the damaged area. This procedure is repeated several times: pressure, vacuum, pressure, vacuum. This is done several times until the chip or crack is completely filled.
It is better to visually check the filling of cracks from the side of the car interior.
At the end of the first stage, the pressure is removed from the injector and excess polymer composition is removed.
4. Crack finishing ... A more viscous polymer is used for it, although in its chemical composition it is identical to the first.
5. Leveling and drying of the polymer composition ... For this, a special transparent film is used. It fits on the surface of the applied composition. In this case, the formation of air bubbles under the film should not be allowed. If necessary, they can be removed by light smoothing. After this, drying and leveling of the applied composition occurs. For this, a special UV lamp is used, although drying can also occur in daylight. When using ultraviolet light, the composition dries completely after 10-15 minutes. In natural light, the time for complete drying increases three times. Then the film is peeled off and the excess polymer is scraped off.
6. Final polishing of the crack ... At the final stage, the restored area of the car glass is thoroughly polished. This requires a glass polish and a soft cloth.
Before self-repair, we recommend watching the following video about repairing a cracked windshield at home:
