Self-repair of glass cracks and repair of chips. Is repairing cracks on a windshield justified? How to cover up a chip on a car windshield

27.08.2018, 11:52 33593 0 Assembly of Motorists

Among all parts of the car body, the most vulnerable spot is the windshield. It is this area that most often suffers from various types of damage. Moreover, no one is actually immune from these troubles. It even happens that even with the most careful driving, defects arise that irritate the driver, glare in the sun and refract light in the evening, interfere with normal visibility, give the car an unaesthetic appearance and, in the end, it is simply impossible to pass a technical inspection with them.

Where do chips and cracks come from? windshield? What are they and is it possible to repair a crack on a car with your own hands? These questions are often asked by drivers who are faced with such an unpleasant problem. It is for them that experts have prepared a number of recommendations on all these issues.

It should be understood that windshields are made using advanced technology and are called triplex. The difference with the usual one is that triplex is several glasses glued together with a special polymer film using the heating pressing method. The result is a mechanically resistant, heat-resistant glass, which, even with strong impacts, does not break into hundreds of fragments, but is covered with a network of tiny defects, similar to a cobweb.

Manufacturers install such glass on cars. If you change the glass and at the same time buy low-quality products, which may cost unreasonably low, then the likelihood of defects increases significantly. However, in both cases it exists.

The main reasons for the appearance of defects on the windshield are:

– getting hit by small gravel, crushed stone or thorns flying from under the wheels of other cars;

– deformation of the body, which can occur as a result of impacts, poor-quality repairs in violation of the geometry, systematic parking with access to the curb, fast driving on uneven roads or potholes, especially on cars with a rigid suspension;

– severe cooling in the heat, frosts, an attempt to get rid of icing on glass using boiling water and other cases that result in sudden temperature changes.

Types of chips and cracks on a car windshield

The following types of defects are distinguished: simple chips, one-sided cracks with damage to only the outer layer, through cracks, ray-shaped or, as they are also called, “stars”, as well as combined ones. Especially vulnerabilities are areas blown by the heater or air conditioner and a few centimeters from the edges. As for small stones, thorns and other objects flying into the glass, it is impossible to foresee anything in advance - a chip appears at the point where it hits the glass.

If the slightest damage is detected, experts recommend immediately taking measures to prevent water or dirt from entering the damaged area. This is done by sticking transparent tape over the damage. If moisture does get in, it is better to drive for several days in dry weather or blow off the damage with a regular fan, and then stick the tape on.

The fact is that if this is not done, then the moisture that gets in forms dirt in the damaged area, which penetrates deep, attaches to uneven edges and is very difficult to wash out, which subsequently leads to a sharp increase in labor costs during repairs. Some “craftsmen” try to carry out repairs on the windshield, not paying attention to the presence of moisture in the damaged area. This is absolutely impossible to do, because after sealing and seemingly normal appearance, the moisture will gradually begin to evaporate, leaving numerous voids that will be clearly visible. And it is already impossible to eliminate them. The result is windshield replacement.

Repair of chips

Obviously, chips, especially small ones on triplex, can be repaired more easily than cracks. For this purpose, inexpensive repair kits are sold in auto stores. The repair of the chip is carried out as follows: At the first stage, the remaining smallest glass fragments are removed. To do this, use the included rod, a regular blade, a pin or a vacuum cleaner. Then the damaged area is thoroughly cleaned and dried. After the preparatory measures, the chipped area is filled with a special compound. For this, a bridge with an injector is used. It is installed exactly above the chip, an injector with filler is attached to it, and a polymer composition is introduced into the chip cavity.

Moreover, its introduction is carried out cyclically - injection and pumping, again injection and pumping. This cyclic introduction of the composition ensures the removal of air and its complete replacement with the polymer. It is better to check for the presence of voids using a good, powerful flashlight. At the last stage, the device is dismantled, dried in direct sunlight or using a UV lamp, removed excess polymer and cleaned with a conventional cleaner.

The entire repair takes no more than 30-40 minutes. As a result, thanks to the frozen polymer composition, which has turned into a kind of laminating film that ideally matches the optical properties of the glass itself, small chips and even “stars” become almost invisible.

Windshield Crack Repair

Repairing a crack in a windshield with your own hands is similar to repairing a chip, but is more painstaking and requires certain skills. All repairs should be carried out indoors in several stages.

1. Relieving tension. If the tension is not immediately relieved from the crack, it may increase. It is the question of how to stop a crack on the windshield that is key during repairs. Therefore, first, at its ends, which diverge from the place of the chip, small holes are carefully drilled with a special drill with a diamond drill of about 0.8 mm. Their depth is determined by the depth of the defect itself. Usually it reaches the middle of the first layer, but it can be deeper. After obtaining thin holes, artificial chips are made in the drilling areas. To do this, use any sharp objects, for example, a sewing machine needle.

Upon completion of these manipulations, smooth chips are obtained that have a cone shape, at which the crack stops and does not go further. This measure can be used as a temporary measure until major repairs are carried out. However, the possibility of spread during further operation of the car still exists. And if this happens, re-drilling is required.

2. Thorough cleaning of damaged areas and drying. Moisture must be completely removed.

3. Repair of a chip at the site of the initial impact according to the method described above– using a bridge and an injector.

4. Filling the damaged area. To introduce the polymer, you can use an applicator with an injector and a pump that creates pressure, but you can do without it. The main thing is to fill it so that there are no air cavities left. To do this, the viscosity of the composition is selected on site so that it can be easily filled. At the same time, a slight mechanical effect on the glass is created from the inside. Warming up the damaged area from the inside is also used. As a result, a capillary effect occurs and the composition fills the defective area more effectively.

5. Final stage – drying, cleaning, polishing. Moreover, to grind glass, which is a rather labor-intensive operation, you can contact a car repair shop.

There are several illustrative examples effective repair of cracks with your own hands.

In conclusion, we should dwell on the question of how to minimize the likelihood of defects appearing on the windshield.

– smoothly adjust the windshield heating power in cold weather;

– do not immediately direct a flow of cold air from the air conditioning system onto glass heated in the sun;

– in cases where it is necessary to replace the windshield, choose only the highest quality products, preferably original ones;

– in cases where impacts are recorded on the glass, immediately stop and carefully inspect the surface to detect even the smallest chips;

– avoid driving over rough terrain or on poor-quality roads, especially in sedans with rigid suspension;

– keep the maximum possible distance from vehicles in front, especially from trucks or those with the “Ш” sign.

Recently, in order to provide additional protection to the windshield, it has been encapsulated - equipped with an additional plastic frame. But that's a completely different story...

Car owners in 99% of cases are faced with a problem - cracks and chips on the windshield. Defects can 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 basic methods and instructions, including do-it-yourself repairs using special kits for restoring auto glass.

Let's start with the types of damage:

Why repair chips and cracks?

4 reasons to repair chips and cracks in your car windshield:

• Danger to the life of the driver. If on windshield crack, the strength of the structure decreases. This means that if the glass is subsequently damaged, there is a high probability of breakage. Often such breakdowns lead to injuries. Decreased visibility, reduced viewing angle.
• Reducing the cost of a car. Buyers pay attention to cosmetic defects when buying a car. If you do not pay attention to eliminating cracks or chips, the cost will fall despite the technical condition.
• Repairing a crack or chip is cheaper than replacing auto glass.
• GOST 2018 states 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 to be used.

How to remove a crack on a windshield?

There are several types of windshield chips and cracks. But they are eliminated according to the same principle. Ultimate Goal glass repair – make the damage invisible while maintaining the strength of the glass.

1. As soon as you notice a crack in your windshield, cover it with tape to prevent dirt from getting in.

1. A hole is made near the damage to reduce the load on the problem area. The crack is cleaned, then the air is pumped out of it.

1. Then transparent polymer materials are poured into the damaged area. After repair, cracks and chips in the windshield are invisible because the mixture is refracted in the same way as glass.

1. To remove a windshield defect, you can buy tools and carry out the repairs yourself, or you can contact a car service center.
2. If the repair of cracks and chips of the windshield is carried out in a car service center, then the light of an ultraviolet lamp is directed to the place of damage to the windshield, under the mixture, which hardens itself within 12-24 hours.

When should glass be replaced and when should it be repaired?

Glass needs to be replaced in 3 cases:

1. The damage extends through the edge of the glass. When the edge is damaged, the strength of the windshield is compromised. There is no point in repairing such cracks, since such cracks will continue to spread. If such glass is damaged again in an accident, it will greatly harm the driver and passengers.

1. Cracks in the heating zone cannot be repaired. Due to temperature changes in winter, the glass may burst. Therefore, if such damage occurs, it must be replaced.

1. 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.

Important to know:

In accordance with GOST, any chips and cracks that do not exceed 15.7 cm must be repaired. You can repair larger damage, but after this the cracks remain noticeable, so it is not a fact that you will pass the inspection.

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

Should I repair it myself or take it to a car service? Pros and cons

Replacement and repair of windshield in a car service center

Car services provide repair services for windshield damage of varying complexity.

When long cracks and numerous chips occur, you need to contact a car service. There is no point in trying to repair it yourself in such cases. This is wasted time.

Attention:

If you try to repair a long crack yourself, you can harm both the car and yourself. Glass in which cracks are not repaired correctly will burst while driving. Airbags won't help here.

The service's professional craftsmen will do the job in 1–2 days. In 50% of car services, customers pick up the car 2-3 hours after they give it to the mechanic.

Cost of windshield repair at a car service center

The price of repairs at a car service ranges from 300 rubles to 5-7 thousand rubles. However, the high price of the work is associated with expensive car models. As a rule, the cost at a car service is comparable to purchasing a windshield repair kit or tools.

Some car dealerships have a set price for repairing a centimeter of crack. In them, the final cost of the work is calculated based on the length of the damage.

If you repair it yourself, the price will depend on the cost of tools and materials.

Note:

If the damage is minor, it makes sense to buy tools or a special kit and repair it yourself. The polymer mixture to repair damage is enough for 2-4 applications. This will save you money on subsequent repairs.

DIY glass repair

To perform the windshield restoration procedure yourself, you will need the following tools:

1. A polymer that will be used to seal the damaged area. You need to choose a material that hardens quickly and has the same refractive index as glass.
2. Injector and bridge. Needed to introduce the adhesive mixture into the chip. It is preferable to choose metal models. Plastic analogues are short-lived.
3. Pump to remove air from the damaged area. Sometimes used to inject polymer under pressure.
4. Diamond drill. It is necessary that the rotation speed of the drill be regulated. Using a drill, drill holes in the windshield to relieve stress from it.
5. Scriber. This is a device for cleaning the damaged area from fragments.
6. Flashlight. To carefully inspect the damage for bubbles.

Or use ready-made kits for self-repair.

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

• Cleaning the damaged area from dirt and debris.
• Drilling. At this stage, drilling is carried out in the direction of the crack expansion. through hole at a distance of 2 mm. This will relieve the stress on the glass and prevent the damage from spreading.
• Cleaning the crack with a scriber.
• Preparation of the polymer composition for use.
• Preparing the injector for use.
• Pouring glue.
• Removing the injector from the windshield.
• Installation of an ultraviolet lamp (if available). 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 with a napkin for 5 minutes.

Drilling and cleaning with a scriber can be neglected if it is necessary to carry out the work quickly.

What DIY kits are there on the market?

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

In general, the instructions for almost all repair kits contain recommendations and step-by-step guides for their use. Follow these instructions and our tips from experience, and you can have your windshield repaired in no time and with minimal effort.

Meanwhile, it is important to know which cracks and chips in your windshield you can repair with a repair kit, and which you cannot. So, the repair kit works great on broken pieces of glass, any types of chips or splinters, but often they cannot do anything with real growing cracks that periodically increase in size.

Have you started windshield repair yet? Has the crack spread and is obstructing your view behind the wheel? No problem! Specialists of the Autostudio 23 company, using advanced technologies and materials, will eliminate cracks and chips in 30 minutes, depending on the complexity of the damage.

Attention! Do not carry out this repair under the scorching sun, otherwise in such conditions the glue will quickly harden, and the repair of the crack in the windshield simply cannot be done properly. Prepare the windshield for repair: wash it with plain water, but thoroughly so that no dirt or dust remains. You cannot add anything from detergents to the water for the simple reason that it is unknown how these detergents will react with the glue with which we will fill the crack.

Step #1 (optional): Drill out the crack

First of all, if the crack tends to increase in size (a clear indicator of this is that it has already increased, having once been smaller), then you need to drill out its ends to prevent its spread. To do this, cover its ends with regular tape where you will drill. Place a thin diamond drill bit for glass in the drill and carefully, without pressing too hard on the glass, begin drilling a hole at one end of the crack, approximately 1-2 millimeters from its end towards the continuation. After this, press on the crack so that it reaches the drilled hole on its own.

Step #2: Clean the glass

The second step in windshield repair is to wash and clean the damaged area of ​​the windshield. After washing, use a scriber or blade to clean out any tiny pieces of glass from the crack or chip. Any unwanted particles of glass or dirt inside the damaged area can ruin all our efforts, so they must be thoroughly cleaned. Also, make sure that the glass is completely dry after washing - especially so that no moisture remains inside the crack or chip itself. Therefore, it is better to dry it.

Step #3: Install the bridge

Once the crack is cleaned and properly treated, place the bridge on the suction cups so that the center threaded hole is directly above the chipped area. Press the suction cups firmly into place. Don't worry if you miss the center a little the first time - try again and again. In addition, most bridges have legs that are adjustable for reach between the suction cups and central hole- just twist them in one direction or another, and you will understand that they unscrew and tighten accordingly.

Step #4: Install the applicator

After installing the suction cup directly on the damaged area and centering the hole towards the chip or crack, screw the applicator tube into this hole along the threads. You will need to screw it in tightly - really, tightly - but do not use any foreign tools for this, screw it in by hand - this will be enough.

Step #5: Make sure the applicator is centered on the chip

Windshield repair depends primarily on the correct alignment of the tools, and it is very important that you re-check the position of the thread applicator in relation to the crack or chip. Do this check from inside the car - this will give you a better idea. The rubber end of the tube should be directly on top of the crack in the windshield. If not, unscrew the applicator back and move the bridge again.

Step #6: Add glue to the applicator

Now it's time to open the tube of glue (also called resin) and add it to our applicator tube. You don't need a lot of resin to make a quality windshield repair, but you also shouldn't skimp. Often you have to start from the instructions, but use twice as much glue as indicated in it. So, if you need to add 2 drops of resin, add more - 4 drops just in case, but not more, as this will add a lot of time to the hardening process and, in addition, you will simply throw away excess glue.

Step #7: Screw the plunger into the applicator

Immediately after adding glue to the repair kit, insert the plunger into the applicator and tighten it to the very bottom. The piston, screwing in, creates pressure to push the glue into the crack. You will be able to understand when you need to stop screwing in the piston, based on the difficulty - when it starts to screw in more difficult due to the pressure that has arisen. Once you have screwed the plunger in to the desired pressure, wait a couple of minutes and then loosen the plunger to allow any air bubbles in the resin to escape from the resin, then tighten the plunger again. Thus, within a few minutes you will fill the crack with a homogeneous adhesive composition without air bubbles.

Step #8: Detach the bridge and install the finishing film

After you've given the glue a few minutes or so to fully penetrate the glass crack or chip, remove the suction cup bridge completely from the windshield. Then quickly apply the finishing film to the still wet repair area. Using a blade, carefully bend the glue protruding above the surface of the glass to the edges of the film. Just don’t overdo it so much that the glue forms, on the contrary, a convex shape, a hole on the surface of the glass.

In addition, just in case, secure the film with tape, because if you are repairing a crack or chip in the windshield on a windy day, then you will have good chance lose the film, which will be blown away by the wind.

Let the glue under the film dry completely. You don't have to worry about overexposing the film, because there is no time limit for the glue under the film to dry. At the same time, under no circumstances should you remove the film while the glue in the chip has not yet dried. On average, ten minutes should be enough for this, but check the instructions for the repair kit for this time. Next, carefully remove the film from the glass and enjoy the result of your jewelry work. You should be even more proud of yourself if you can’t even find where that crack was on the windshield of your car.

Anything can happen on the road. A fairly common situation is when various kinds 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 your 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 makes visibility difficult.

2. The cracks subsequently tend to grow, which leads to the future disintegration of the windshield.

3. And the most important reason is that a damaged windshield is a major hindrance if it's time for a vehicle inspection.

If you suddenly find a chip or small crack, you don’t have to immediately rush to the car market and, in some cases, it can be repaired at a car service center. It will cost you much less, because it’s not enough to buy it, installation also costs a lot of money. In addition, a replaced windshield is a serious stumbling block when selling a car. You can’t prove to the buyer why you replaced it, what 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 ordinary transparent tape. This will protect the damaged area from dirt getting inside the crack, since if dust or dirt gets into the cracks, it will seriously increase the repair costs. It also happens that car repair shops do not restore windshields at all if dirt has gotten into the cracks.

If repairs cannot be made immediately after damage occurs, do not wash the glass with chemical detergents. They will not allow the glue to cure properly.

Repairing a damaged windshield is done by pouring special polymers into the chips and cracks. These polymers have very good optical properties, which, in terms of transparency, are in no way inferior to ordinary glass. Also, such polymers have good shock resistance.

An important factor is to choose a suitable car service for the work. After all, prices for work in each individual auto repair shop can vary significantly. Therefore, before starting repairs, show the “front of work” to an auto mechanic so that he can immediately tell you how much the repair will cost you.

If, on at the moment, financial problems do not allow you to immediately begin repairing the windshield, then you can ask the master, temporarily, just drill out the crack. This way, you will prevent further growth of the crack, and it is also an inexpensive operation. By doing this, you can save money when serious repairs begin.

By the way, repairing chips and cracks with your own hands is quite acceptable, because car services do not always undertake such work; it is easier for them to completely replace the windshield. And if you completely follow the repair technology, you can easily do everything yourself, since the necessary materials are sold everywhere.

Equipment and materials for windshield repair.

So, let's list what is needed to fix a chip or crack on the windshield with your own hands.

• Adhesive polymer for sealing cracks. When purchasing, you need to remember that its hardening time should be short. As for transparency, each product has its own transparency coefficient, and it must correspond to that of the glass.
• 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. You should definitely take a diamond drill.
• Bridge and injector. They inject glue into the crack. They come in disposable (plastic) and reusable (metal) types.
• Pump. They remove air from the damaged area.
• Scriber. Needed to cleanse the area around the damage.
• Electric flashlight, to clarify the boundaries of the crack, and to detect bubbles in the glue.
• To speed up the drying process of the polymer, it is useful ultraviolet lamp.

Well, in order to clean surfaces, prepare cleaning liquid and wipes.

How to remove chips and cracks on the windshield?

The work area must be thoroughly washed and dried, because the remaining moisture and dirt will not allow the glue to properly fill the damage. Clean the crack thoroughly, using a blade to remove any splinters and small debris. After this, blow out the damaged area with a compressor or pump, and you can start working. And try to keep the glass away from direct sunlight.

The first step is to “relieve the tension” from the damaged area so that during the work the crack does not grow even larger. To do this, along the edges of the crack, drill a through hole, at a distance of 2mm in the direction of elongation. Then, with a little effort, bring the crack to these holes.

Install the bridge with the injector so that the gander is directly above the desired location.

Slowly feed the adhesive polymer into the crack. Buy glue in reserve. It is easy to remove excess polymer, but if there is not enough of it, work will go down the drain. Once 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.

Once everything has hardened, you can move on to sanding and polishing the windshield.

If you are interested in how damaged windshields are repaired, here is a detailed training video on the technology for their repair.

Chip on the windshield, what to do in such a situation? It appears when struck by a small stone, causing a piece of glass to break off. First of all, you should use tape and seal the chip on the windshield, preventing dirt from getting in. To prevent the glue from leaking inside, it is best to put paper or a rag on the chipping, and then glue it over. It is not advisable to turn on the heating or direct the heater airflow to the defect site.

Timely repair of chips will prevent the formation of cracks, which are much more difficult to deal with.

Timely repairs will prevent. Repairing a chipped car windshield does not require much experience or knowledge. All you need is care, time and a windshield chip repair kit.
It is better to do repairs in the garage, in sunny, dry weather. A hairdryer may be needed. A windshield chip repair kit can be purchased at any auto store. It must be fully packaged and not past its expiration date. Otherwise, the polymer will be powerless.
First you need to carefully inspect the windshield. If cracks have already appeared, then the technology for repairing chips and cracks of the windshield will be as follows:

• use a small electric drill with a diamond drill bit;
• to prevent further growth, drill the edges of the cracks;
• thoroughly clean the defect area using a hairdryer, plain water without chemicals and soap, and a needle from the kit;
• dry the defective area well;
• start repairing chips on the windshield using the kit, strictly following the instructions;
• level the polymer mass using a special film;
• Carefully remove excess glue with a blade;
• It is advisable to grind and polish the entire windshield.

Attention! The polymer hardens within 10 hours!
Small scratches, or better yet, GOI paste. A little paste should be applied to a clean piece of felt. Use circular movements to rub it onto the defective areas. Then rub another portion of paste in the opposite direction. Polish. Wash the work area.

How to remove small chips on a windshield

Do-it-yourself windshield chip removal

The principle of repairing chips is that the cracks are filled with polymer, which, after grinding, strengthens the glass up to 97%.

Many car owners believe that such a small defect is completely harmless and not worthy of attention. But this is a big misconception. If no measures are taken in a timely manner, such small chips will increase in size over time and cracks will appear. You can remove a small chip on your windshield yourself.
How to repair a chip on a windshield is described above in this article. The principle of repair is that cracks are filled with polymer, which, in turn, after grinding, visually restores aesthetics and strengthens the glass itself up to 97%. Which is also an important aspect.

Adhesive for windshield chips

To remove chips on the windshield of a car in the modern car market, there are different types glue. The most popular polymers:

• Poly 500 PL – 108;
• Pit Filler Plus PL – 116;
• Poly 25 PL – 102;
• Pit Filler PL – 106;
• Super Pit Filler PL – 106S;
• Permatex 16067 glue for repairing Bull's Eye glass.

Where to repair a chip on a windshield

Types of car windshield chips

How much it costs to repair a chip in your windshield depends on the level of damage.

It is not possible to repair chips on the windshield yourself if the chips have a diameter of more than 3 cm, and the cracks are longer than 20 cm. It is recommended to repair such defects in a car service center. Experienced craftsmen will tell you exactly whether it is worth eliminating them, or whether it is better to replace the entire glass completely.
How much it costs to repair a chip on a windshield depends on the level of damage (number of chips, their diameter, number of cracks and their length). And also from the money spent on repairing chips on the windshield. It won't be more expensive than replacing the entire glass.

Windshield protection from chips

Contrary to popular belief that your windshield cannot be protected, there are real ways to protect it from unpleasant surprises. The article presents methods on how to protect your windshield from chips:

The most reliable way to protect the windshield, and the entire car, is the driver’s accuracy and vigilance. It is worth reducing your speed off-road and maintaining a distance between your vehicle and the vehicle in front.

Inspection for a chip on the windshield

GOST 51709-2001 clearly defines the requirements for compliance of vehicle components, as well as the windshield. Chips that interfere good review, are considered dangerous by traffic police officers.
If chips and cracks are located in the area of ​​the windshield wipers, then such a car will not pass inspection.
