An article on how to properly change car glass. Important nuances of the process. At the end of the article - an interesting video about the intricacies of replacing auto glass.

The content of the article:

Replacing car windows is not such a difficult procedure as experts are trying to assure motorists. Having at hand a few tools, high-quality glass, some skills and a little patience, you can replace the auto glass yourself.

Replacing the side glass of the car

Unlike the windshield, the side windows are more fragile, therefore they break thoroughly - immediately and into small fragments. Scotch tape and film are a good way out, but you still have to put in a new glass. You can go to the workshop and pay not only for a new window, but also for the work of the wizard. Or try to do everything yourself.

This will require:

new glass;
screwdrivers - Phillips, flat, end;
latches for fixing the sheathing (it is better not to use the old ones);
brush for cleaning splinters and other debris.

Work order

Remove the door trim first. To do this, you should:
- using a Phillips screwdriver, unscrew the fixing bolts securing the armrest and remove it;
- unscrew and remove the window regulator handle (the plastic plug can be easily pushed off and removed with a small thin screwdriver);
- remove the handle that opens the car door;
- loosen the fixing elements that hold the upholstery itself and disconnect it from the metal frame of the door.
After the upholstery has been removed, the power window lever should be reinstalled and locked in the "glass down" position.
Using a socket screwdriver, unscrew the fastening bolts on the "frame", remove the seal and clean the place from glass fragments.
Then turn the power window to the "slightly up" mode so that the screws holding the pressure plate are in view.
The screws should be loosened, and one of them should be unscrewed completely, pulling the loosely fixed cable to the side.
Take a new glass and, tilting it upside down into the interior, insert it into place. Then fix the glass with the clamping bolts.
Return the upholstery and the rest of the door elements by repeating all the manipulations in the reverse order.

Features of windshields and their replacement

Unlike the side ones, the windshields are made using special technologies and are reinforced. Their duties include not only the functions of windows, they protect the driver and passengers from external hazards (flying stones, impact in an accident, etc.), and also act as a supporting element for the car body, or rather its roof.

Windshields are manufactured using various technologies and are usually two reinforced glasses connected together and having a reinforcing layer. Therefore, such glasses almost never shatter; it takes more than a stone hit or a medium-sized impact.

The protective and fixing qualities of windshields largely depend on the quality of the installation. It is recommended to carry it out in the workshop, entrusting the matter to specialists. Incorrectly placed glass can have deviations in accordance with GOST and quickly fail, warp, fall out or noticeably lose its protective qualities.

But this does not mean that reinstallation cannot be done on your own. You just need to approach this matter with all responsibility.

Windshield replacement

Would need:

a string or cutting knife to remove old sealant;
new glass;
primer mixture;
surface degreasing agent;
adhesive tape for fixing glass;
glue (sealant) for glass installation;
pneumatic gun for applying adhesive.

You can purchase everything you need either individually or in a special kit for replacing auto glass.

Work order

Step 1. Remove old glass or its remnants

To do this, you will have to use a special knife or string. They are placed inside and outside the glass and cut the sealant on which it is attached. The main thing in performing this procedure is not to damage the front panel of the passenger compartment.

Step 2. Remove the old glue

This can be done using an ordinary retractable knife sold in hardware stores. It is advisable to remove the old layer completely, but if it is difficult, then the remnants of the used glue will not cause much harm.

Step 3. Degrease the surface

For this purpose, a special composition is included in the kit, but if it is not available, ordinary acetone or another degreasing agent will do.

Step 4. Prime the installation site

There are several nuances to consider here:

Do not apply a primer on the remnants of the old adhesive, only on metal parts of the body.
The primer mixture is applied in one layer, along the line of extrusion of the sealing compound.
A primer is also applied to the glass in the area of contact with the sealant to avoid UV exposure to the latter. Otherwise, the sealant will begin to deteriorate under the influence of ultraviolet radiation, which will affect the quality of the installation and the life of the glass.
After priming, areas with the remaining old adhesive are degreased.

Step 5. Apply sealant along the gluing line

Pay attention to a few nuances:

If the container for the adhesive sealant does not have a special tip, then the packaging must be cut off, maintaining a large angle so that the contents are squeezed out in the form of a cone tapering upward.
The sealant is applied using an air gun or compressor.
It is recommended to heat the mixture to about 40 degrees before applying.
It should be applied evenly to avoid the formation of voids or lumps of the mixture.

Step 6. Insert and fix the glass

The glass is rubberized along the contour and is applied to the applied sealant and gently pressed. After that, it should be secured with tape and left to dry.

Important points

No matter how the owners and workers of the workshops frightened motorists with the complexity of installing glass in the car, and the latter did not insist on the opposite, the truth is somewhere in between. Of course, a person without experience can make a mistake and do something wrong, but with a careful approach and minimal skills, it is quite possible to install glass in a car.

And to minimize the risk of error, you should follow some rules:

Select glass, taking into account the make and model of a particular car.
Follow all instructions on the adhesive packaging carefully.
Since the mixture is very dense, it is advisable to use a high-quality reliable pistol that will not break during work.
Before gluing the glass, you need to attach it to the installation site and check how well it fits by marking the contact points.
The first few days after installation, do not bang the doors (this creates pressure on the glass) or perform other harsh manipulations with the machine. It is best to leave it alone until the glue has completely hardened.
It is advisable not to drive the car for at least 48 hours after the windows have been glued in. If this is not possible, you should wait at least a few hours before driving.
In no case should the fixing tape be removed in the first two days; the glass will lose support and may loosen. Therefore, if you plan to go on the road after installation, then the adhesive tape should be chosen transparent so as not to interfere with the view.
The car must not be washed for at least 48 hours, and in general should not be wet, for example, in the rain. This disrupts the curing process of the sealant.
Glue and glass for installation should be purchased only from reliable manufacturers.
The surface for applying the sealant must be absolutely dry.
Remove old glass with protective gloves so as not to harm yourself. It is also advisable to wear a mask that will protect your eyes. Cracked, unstable glass can cause unpleasant surprises and serious injury.

When choosing auto glass, you should focus primarily on your material capabilities. Of course, branded glasses designed for a specific car make and model are ideal. But the prices for such products are several times higher than the prices for licensed copies. And the latter are often in no way inferior to branded products. Even Russian-made autoglasses have good characteristics, for its price segment, of course.

When replacing a protective glass on a smartphone, few people do not worry about observing the rules and perform re-gluing with improvised tools. As a result: there are scratches on the phone, the coating is uneven, covered with bubbles, or simply does not stick tightly

When replacing a protective glass on a smartphone, few people do not worry about observing the rules and perform re-gluing with improvised tools.

As a result: scratches remain on the phone, the coating lays down unevenly, becomes covered with bubbles, or just doesn't stick tightly.

Instructions: how to install a protective glass on your phone

We have prepared a short instruction manual for those who want to install the glass on their own.

The article contains basic information, but for the sake of completeness, we recommend watching the video with detailed description stages of installation.

Removing old glass: what is important to remember

You have to understand that glass does not stick to the screen because of a special adhesive coating. The adhesion of the film to the smooth surface of the touchscreen is due to static. An attempt to remove it by prying it with a fingernail or (much worse) with a knife will result in damage to the screen and the phone case.

Even using a special suction cup can lead to unpleasant consequences. Remember, do everything smoothly. Pressing firmly on the Velcro, you risk damaging the cables or ripping off the screen module. A vacuum is formed between the glass and the film, which will resist the adhesion of the coatings. But even if the suction cup adheres well to the film, there is a chance of damage to the sensor when removing the protective glass. Therefore, proceed consistently and carefully.

What to prepare for installing a protective glass:

a pick (or a thin plastic card) - it is better to take 2 pieces;

silicone suction cup (if you already have experience with reinstallation, you can do without Velcro);

a napkin or a piece of lint-free cloth;

an alcohol-based glass cleaner (pure alcohol or perfume will also work);

medical gloves (silicone or rubber).

Once armed with these tools, the job will take less than two minutes.

Brief description of the process

Make sure your hands are free of dust or lint before starting work. It is impossible to see the smallest particles on your fingers, so play it safe and wear medical gloves. They are thin and fit snugly on the arm, so they will not interfere with your work.

Next, install the suction cup on the area of the phone with damaged glass, where there are fewer fragments and cracks. Gently attach the Velcro to the corner of the screen, and then press down slightly, glue it to the glass. Take the pick and pull the suction cup towards you, only gradually increase the force, otherwise the glass will come off along with the screen.

As soon as you feel that the glass is peeling, deepen the pick.

When the glass around the perimeter peels off ~ 80%, feel free to pull the suction cup and tear off the old screen.

We glue new glass

Remove dust and fingerprints before applying new coating. A lint-free cloth is suitable for this: first moisten the screen with glass cleaner and degrease the surface with a prepared cloth.

Take the protective glass by the edges (put on gloves beforehand).

Carefully remove the adhesive protective surface on the film (keep the glass near the phone, otherwise air dust will stick while you carry the film).

Place the glass as close to the screen as possible (align with the center, make sure that all openings for buttons, connectors and the camera pass through the film).

Slowly lower the protective cover onto the screen, press down and smooth from the center to the corners at the same time. Use a dry, lint-free cloth or a thin plastic card to do this.

Remove the shipping protection tape.

It is not always possible to glue the glass to the phone without getting dust and lint. If you see that there are debris under the film, peel off the glass exactly to the place where there is dirt.

You can also use a compressor, a technical vacuum cleaner, or a can of compressed air to blow out dust particles.

If you don't have anything at hand, use tweezers.

Once the dirt is removed, stick the glass back.

The main function of the protective glass of the smartphone is to take the blow, protecting the touchscreen from damage. When this happens, it often becomes unusable, covered with chips, cracks and other damage. The level of protection from this drops significantly, in addition, the view of the display deteriorates, and the smartphone loses its attractiveness. To change the cover to a new one, you must first remove the broken protective glass from the phone. And here difficulties arise, which will be discussed in the material.

Precautionary measures

One must take into account important point before removing the old protective glass from the phone. Perfectly smooth surface touch screen, the glass adheres to it very firmly. Usually it is held not by glue (although this also happens), but by electrostatic forces. The two flat surfaces are very firmly in contact, not allowing you to remove the glass, simply prying it with your fingernail. If you take the first one that comes across handy tool(like a knife) - there is a risk of damaging the smartphone display and its case.

Silicone suction cup alone is not enough either. If you stick to a badly damaged glass, a vacuum does not form inside it, and when you apply force, it will jump off. If the grip is good, the suction cup will not come off, but another problem arises. The sensor is fixed in the housing using double-sided adhesive tape or glue, the tensile strength of which is lower than that of a touchscreen and protective glass. Overdoing it, you can rip off the screen module completely, damaging its cables. Therefore, you need to act deliberately and consistently.

How to remove the glass from the phone and stick a new one

Before removing the broken protective glass from your phone and replacing it, you need to prepare and arm yourself with a set of tools and tools.

This will require:

a pick, spatula or thin plastic card (preferably 2 pieces);
silicone suction cup - optional;
lint-free napkin;
glass cleaner (preferably alcohol-containing), alcohol, vodka, or perfume based on alcohol (perfume, cologne) - to choose;
medical gloves - optional.

Often, a new protective glass can be completed with the necessary devices.

The dismantling procedure is extremely simple and takes a minute.

Before removing the protective glass from your phone, you need to wash your hands with soap and water and dry thoroughly, or just wear rubber gloves. This is to prevent fingerprints and streaks from appearing on the screen surface.
On broken glass you should find the most complete corner, where there are no chips and other damage (or there is, but in the smallest amount). There you need to attach a sucker, pressing it to the screen.
The corner to which the suction cup is glued must be pry off with a pick, spatula or suction cup so that the edge of the glass peels off. This requires a slight pull on the suction cup at the same time. It is important not to overdo it, so as not to rip the screen before a gap forms between it and the glass! If there is no suction cup at hand, you can simply slide the pick deeper into the gap.
As the glass peels off, the pick / spatula / card should be deepened. If the screen is large, it is recommended to work with two tools at once, moving them in different directions.
The final touch is to pull the suction cup towards you until the glass is completely detached. You can grab the edge with your fingers and do the same.

Phones often fall, glass, as the most fragile part, breaks first. It would seem that there is no problem to go to replace the glass on the phone, but in practice everything turns out to be not so simple.

Previously, the glass on the phone was changed separately, and the glass cost a penny. They are still inexpensive, but with the advent of the era of touchscreen phones, the procedure for replacing glass has become much more complicated. What is the current cost of replacing glass on a phone, taking into account the work?

If you have a touchscreen phone, and the glass is broken on it, a replacement is required, then you need to know the following:

Modern touch phones there are two types: those phones in which the sensor is connected to the glass, accordingly changing the glass, you also change the sensor, and the cost of the touch glasses is already much higher, since in addition to the glass itself, there is also a touch panel with a loop, which has a connector on motherboard phone. Still, replacing the touch glass is not as expensive as replacing the glass itself on more expensive models.

The most advanced phone models, company flagships such as Iphone 4, Iphone 5, Samsung Galaxy S3, Galaxy S4, Htc one, Nokia Lumia 920, Sony Xperia Z and others have a more complex screen design: the phone screen consists of an LCD display, which actually transmits the image, a sensor (touchscreen) responsible for pressing, and glass, which is protective and decorative. In this case, the screen module is one-piece, the components are glued together in an industrial way, and according to the manufacturer's instructions, the entire screen is changed.

Glass replacement procedure.

Nevertheless, the glass can still be changed. The procedure for replacing glass on top-model phones is as follows: the display module is heated using a special hair dryer, or a special heating pad, the glue with which the glass is glued to the sensor softens, then with a knife, a thin spatula, a plastic playing card, a special molybdenum wire and the like, the glass is detached from the screen. Then the remnants of the glue are removed using a special solvent, a scraper, napkins, soft cloth, etc. New glass is placed either on double-sided tape or on a special UV glue (similar to the factory one).

The description looks pretty simple, but in practice it is far from the case.

Firstly, it is extremely difficult to achieve uniform heating of the surface of the display module, there is a danger of overheating the display and the sensor, after which either the image will disappear or the sensor will not work correctly. This can manifest itself both immediately and after a while.

Secondly, it is possible to remove the glass without problems only if there are one or two large cracks on the glass, but in the case when there is a cobweb of small cracks on the glass, the glass will crumble, and it is easy to damage the sensor with fragments, as a result, you will still have to change the entire display module. Also, from a blow in the display, there may already be microcracks, which do not manifest themselves in any way before the procedure, but when heated and / or pressure on the glass can lead to failure of the LCD itself.

Thirdly, cleaning the sensor from the glue is also not useful for the phone, the glue is removed with a scraper, cloth, etc., the sensor is seriously affected, which can also lead to its failure.

And finally, in most cases, the masters put the new glass on double-sided tape glued along the perimeter of the screen, it is impossible to ensure a snug fit of the new glass, over time, dust will accumulate under it, and the tape itself may come off.

Not everyone knows how to put new glass on glue, not only special glue is required, preferably German, but also an ultraviolet lamp (the principle of glue hardening, like in a dental office, when a photopolymer filling is placed), and preferably special equipment for the display and glass to provide 100 % exact hit of the glass in its place.

Glass replacement takes up to three hours, it is extremely painstaking and requires very high qualifications of the master. At the same time, if something does not work out, then the master is also responsible for this, it is impossible to explain something to the majority of clients. No guarantees can be given for the successful outcome of the operation.

That is why most professional workshops will tell you that the glasses do not change, and will suggest replacing the entire display module. Of course, you can find a master or a service where they will take it up, but be sure that the glasses are changed there in an amateur way, the probability of success is 50/50, the likelihood of further performance and preservation appearance phone even lower.

Is a fragile and very important thing. You can say in the style of "Captain Obvious" that if it is damaged, the phone becomes impossible to use, but people are more interested in something else: is it possible to replace the screen on the phone by yourself? Considering that in service center for this procedure, they usually take at least 1000 hryvnia (even for a budget device) - the issue of saving becomes acute. We will try to find out about the intricacies of the replacement below.

Any material should start with theory. If you came here from a search engine, entering the query "how to replace the screen on a phone with your own hands" - new knowledge will definitely not hurt. If the purpose of reading the material is to obtain some new information, in addition to those learned earlier, this subheading need not be studied.

Touchscreen modern smartphone is a complex device consisting of several functional elements... The main ones are the matrix and the touchscreen; frames, keys, backlighting elements and, of course, loops, in the amount of 1 to 3-4 pieces, can also be present.

Matrix- a liquid crystal or light-emitting diode panel, which contains an array of pixels that form an image. On the front side it is covered with a very thin layer of glass, on the back it has a stainless steel case. It is also equipped with a ribbon cable for connection to the board, it may have other small elements on it.

Touchscreen (sensor)- a transparent glass touch panel that covers the entire front of the smartphone. It is a thin sheet of glass (less often - plastic), on which is applied from the inside transparent layer conductive material, from the outside - oleophobic spraying (optional).

V individual cases(lately - more and more often) the touchscreen and the matrix of the smartphone are one whole. They are delivered as a single module and change together. This design is called OGS.

OGS screen(from the English one glass solution - a solution with one glass) - a type of smartphone screen in which the sensor and the matrix are connected together in the form of a "sandwich". A distinctive feature of OGS-matrices is a very thin layer of coating that protects pixels, since the main element of their protection is the sensor.

Whether it is possible to replace the phone screen on your own depends on the reader's ability to work with tools and the type of matrix. Some smartphones lend themselves very well to home repair, while with others - not even every SC master can handle it. We will discuss below which screens can be replaced even without experience, and which ones should be entrusted to a specialist.

How to replace the glass on the phone screen yourself

The touchscreen of a smartphone is the first to take a hit when dropped, so it suffers more often than a matrix. Therefore, the number of calls to the SC caused by glass damage is greater than the number of cases of a broken matrix. However, this is not always encouraging, since replacing one touchscreen sometimes costs more than a complete module. This situation is caused precisely by the use of OGS screens.

To divide the OGS display into a touchscreen and a matrix, to replace a damaged sensor, you will not be able to do with simple tools (suction cup, screwdrivers, knife, pick). Replacing the sensor on the OGS screen in the SC conditions occurs in approximately the following order:

Disassembly of the phone.
Removing the module from the smartphone case.
Fixing and warming up the screen on a special stand.
Separation of the matrix and the touchscreen with a special thin nylon thread.
Cleaning the matrix from glue.
Placement of the matrix in a special stencil, application of photopolymer transparent glue.
Installing a touch screen into a stencil, removing excess glue between it and the matrix.
Irradiation of the gluing with a UV lamp to polymerize the glue.
Installing the module into the case.
Assembling a smartphone.

As you can see, without special equipment (a heating stand, stencils, a transparent photopolymer and a UV lamp), it will not be possible to replace glass on an OGS screen on your own. Unfortunately, now such screens are installed in most Samsung smartphones, LG, Sony, Xiaomi, Meizu and, in general, almost all devices, more expensive than UAH 3000. Apple has been using OGS displays since the iPhone 4S. Therefore, independent attempts to change the sensor (without a matrix) on these devices are justified only if there is a lot of time, a desire to learn and if the phone is not a pity.

The video shows how a person with experience changes the sensor on the OGS display using a minimum of tools:

For the desperate: how to replace the glass on the OGS screen yourself

If the budget is limited and you don't want to overpay for the damaged matrix - this section worth reading for general information only. It is better to immediately purchase the complete OGS screen module, and not risk it. The editors are not responsible for broken screens, torn cables and other consequences of unsuccessful experiments.

Owners of some flagship smartphones(HTC One M series, Samsung Galaxy released after 2015, and more) self-intervention is contraindicated. Disassemble them without experience, without damaging the body parts, impossible.

Disassembly requires the following tools and equipment:

Curly screwdriver set(cross and star), for disassembling a smartphone.
Plastic card or guitar pick, spatula.
Hair dryer, capable of heating the screen to a temperature of 70-90 degrees (normal for hair is suitable).
Thin nylon thread or string to split the module.
Gloves(workers and medical).
Rubber suction cup with ring.
Metal flat surface with holes(perforated sheet).
6-8 bolts with nuts(the diameter depends on the diameter of the holes in the sheet, the length is 2-3 cm).
Photopolymer glue hardened by UV radiation.
Transparent glue that cures in the atmosphere(for example, B-7000).
Ultraviolet lamp(You can use a regular carrier with an E27 ultraviolet lamp, or you can take a UV manicure camera for nail extension).
Glass cleaner, alcohol, wipes.
