The main function of the protective glass of a 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 coating to a new one, you must first remove the broken one. safety glass from the phone. And here difficulties arise, which will be discussed in the material.

Precautions

There is one important point to consider before removing the old protective glass from your phone. Thanks to the perfectly smooth surface of the touchscreen, 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, just pry it with your fingernail. If you take the first available 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 force is applied, 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 body 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 the 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 suction cup, 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.

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: there are scratches 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.

Replacing the windshield with your own hands will be quite within the power of the average car enthusiast with careful performance of all operations. But many motorists believe that it is possible to replace the windshield only at a specialized service station equipped with professional equipment.

There are many myths and fears regarding the procedure for removing and installing a windshield. Therefore, car owners rarely dare to do their own replacement or reinstallation. However, with the sequential performance of all operations, it will be possible to carry out the replacement efficiently, quickly and with your own hands.

Why is windshield replacement required?

There are two main reasons that lead to the need to replace the windshield.

1. Penetration of moisture from under the seal.
   Leakage between the glass and the body is due to the presence of a non-glued area. In the absence of a warranty, you will have to carry out repairs yourself. Sometimes it is possible to eliminate the leak when a hole is found by filling the gap with a sealant. If you don't get rid of the leak, you will have to completely re-glue the glass.
2. Damage to the windshield.
   Many motorists have faced such troubles as cracks and chips. They gradually grow, forming a whole "web" on the windshield. In this case, it will not be possible to pass the state technical inspection, and the operation of the vehicle will be unsafe. In the presence of minor damage, it is possible to repair chips and cracks, otherwise the glass must be replaced.

Below we will tell you what tools and materials you need to replace, how to remove the old windshield and replace it with a new one. And at the end of this article, see the detailed video instruction to replace the windshield with your own hands according to all the rules.

Windshield replacement materials and tools

Before you start replacing the windshield, you need to stock up on the following materials and tools:

• metal string with 2 handles;
• awl or pointed wire;
• suction cups for holding glass;
• screwdrivers;
• spanners;
• chisel;
• masking tape;
• adhesive sealant for glass;
• a gun for applying sealant;
• solvent, primer;
• tampons and gloves.

To replace the glass, you will need a closed and dry room (garage or car box). The car must spend at least one day in it.

To do the job efficiently and safely, you need one or two assistants. Before starting work, the car should be washed (how to wash the car properly), especially in the area of ​​the windshield.

How to remove an old windshield

A clean machine must first be set up in a garage or cubicle on a level surface. The procedure for removing the windshield is as follows:

1. Using a flat screwdriver, you need to remove the rubber seal located on the outside of the car.
2. Wipers, plastic protection, moldings are subject to dismantling.
3. In the cabin, cover the dashboard and front seats with foil to protect them from dust and dirt.
4. The seal is removed from the passenger compartment, and the cards of the front pillars are pushed in the area of ​​the latches and dismantled.
5. Now you need to unscrew the screws and remove the sun visors.
6. Existing sensors and wires that go to the windshield must be disconnected and dismantled.
7. An awl or sharpened wire is used to puncture the sealed seam (old glue).
8. A faceted string is inserted into the puncture, after which handles are attached to its edges. It is more convenient to start cutting the old windshield from the upper left corner.
9. It is more convenient to carry out the work of cutting the adhesive sealant together. One fits comfortably inside the cabin, and the other - on the outside of the car. The principle of operation is simple, first one person pulls the string towards himself, and the other keeps his section taut. Then the string moves in the opposite direction. In this case, the string is shifted along the windshield.
10. A piece of sheet metal should be placed in places of the body where the string can touch the panel or skin.
11. When a cut is made around the entire perimeter, the windshield is removed from the car using suction cups.
12. Now it is necessary to clean the body and glass from the old glue (if it will be installed again). This requires a chisel and a solvent.

Everything is clearly shown in the video at the end of the article.

Windshield installation

The installation of a new windshield is carried out in the following sequence:

1. Before applying glue to the surface of the body and glass, it is necessary to treat the contour with a primer. It will improve the adhesion of the surface to the adhesive.
2. Before applying the glue, it is advisable to warm the tube or balloon with a hairdryer or warm water, then it will be more convenient to apply the sealant to the base.
3. A clean rubber seal is mounted on the glass.
4. The dosing tube is cut to a height of approx. 20 mm (width 5 mm).
5. The adhesive can be applied both to the contour of the windshield and to the surface of the body. Most professionals seal glass with sealant. But in the absence of suction cups, it is better to glue the perimeter of the body. It is very important that the sealant bead is continuous. The only joint is made at the bottom in the center.
6. After applying the glue, the windshield must be carefully positioned in the opening. After putting the glass in place, slightly press on it - then it will firmly adhere to the body, and the sealant will fill all the voids.
7. To prevent the glass from accidentally moving, it should be fixed with several strips of adhesive tape.
8. After replacing the windshield, you can install the plastic protectors, side moldings and wipers.
9. Do not slam doors, trunk and hood to avoid vibrations and displacement of glass.
10. In this position, the car must be left alone for a day. It should be remembered that the higher the air temperature in the garage or box, the faster the adhesive will polymerize. At room temperatures below 0 degrees, the sealant will not harden.

The next day, the tape is removed and the windshield and adjacent areas of the body are washed. At this point, you can check the tightness of the resulting seam. If a leak is found, then it is necessary to additionally glue both the inner perimeter and the outer side of the seam. When 100% tightness has been achieved, the vehicle can be completely assembled.

With an accurate and consistent performance of all operations to replace the windshield, the result will delight the car enthusiast. A high-quality do-it-yourself installation often eliminates ridiculous mistakes that even masters in a car service make in a hurry. The main thing is that they are not afraid to master new stages of car repair.

Video instruction: how to replace the windshield with your own hands

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.

The order of work

1. 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.
2. After the upholstery has been removed, set the power window lever in place and lock it in the "glass down" position.
3. Using a socket screwdriver, unscrew the fastening bolts on the "frame", remove the seal and clean the place from glass fragments.
4. Then move the power window to the "slightly up" mode so that the screws holding the pressure plate are in plain view.
5. The screws should be loosened, and one of them should be unscrewed completely, pulling the loosely fixed cable to the side.
6. Take a new glass and, tilting its upper side towards the interior of the passenger compartment, insert it into place. Then fix the glass with the clamping bolts.
7. 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 have to approach this matter with all responsibility.

Windshield replacement

Required:

• 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.

The order of work

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:

1. Do not apply a primer on the remnants of the old adhesive, only on metal parts of the body.
2. The primer mixture is applied in one layer, along the line of extrusion of the sealing compound.
3. 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.
4. After priming, areas with the remaining old adhesive are degreased.

Step 5. Apply sealant along the gluing line

Pay attention to a few nuances:

1. 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.
2. The sealant is applied using an air gun or compressor.
3. It is recommended to heat the mixture to about 40 degrees before applying.
4. 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:

1. Select glass, taking into account the make and model of a particular car.
2. Follow all instructions on the adhesive packaging carefully.
3. Since the mixture is very dense, it is advisable to use a high-quality reliable pistol that will not break during work.
4. Before gluing the glass, you need to attach it to the installation site and check how well it fits by marking the contact points.
5. The first few days after installation, do not slam the doors (this creates pressure on the glass) or make other harsh manipulations with the machine. It is best to leave it alone until the glue has completely hardened.
6. 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.
7. 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.
8. 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.
9. Glue and glass for installation should be purchased only from reliable manufacturers.
10. The surface for applying the sealant must be absolutely dry.
11. 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 present nasty surprises and seriously injure.

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.

Articles and Life Hacks

Broken glass is one of the most common problems for mobile device owners. Our article will help you figure out how to replace the glass on your phone, and also tell you what we need for this.

Replacing glass: when to do it

Glass is the most fragile part of our device, and therefore it breaks first when dropped.

But if earlier it was inexpensive to replace it, today it can become a real problem. With widespread distribution touch phones everything has changed, and the procedure has become much more complicated.

In addition, it is not cheap (do not forget about the cost of the work).

Modern mobile devices can have a touch panel connected to glass. In this case, a separate glass replacement is not possible, and this increases the cost of replacement.

Nevertheless, it is still not as expensive to do as changing the glass on expensive flagships. The most advanced mobile devices (like the Xperia Z from Sony or the Galaxy S4 from Samsung) have a rather complicated screen design.

It consists of a liquid crystal display that transmits images, a sensor (also known as a touch-screen) that reacts to finger touches, and glass.

The latter performs not only decorative, but also protective functions. Note that the screen module of such smartphones is an integral element, all the components of which are glued to each other.

The manufacturer's manual requires a complete replacement.
Of course, in the absence of sufficient skills, it is better to contact a service center.

If we decide to do it ourselves, it is recommended to look on YouTube for a video instruction on replacing glass on our device model. Here are some tips.

Replacement procedure

• The replacement begins something like this: we heat the display module with a special hair dryer, after which the glue becomes softer, and we get rid of it using a plastic tool.
• Residues are removed with solvent and napkins. The new glass is attached to 2-sided tape or UV glue.
• At first glance, everything seems simple enough, but in practice, difficulties often arise.
• Firstly, it is very difficult to achieve uniform heating of the display module surface.
• There is always a risk that we will overheat both the display and the touch-screen. We can do irreparable harm mobile device.
• It is easiest to remove the glass yourself if there are large cracks on the glass surface.
• If the cracks are small, the procedure is rather risky, as the glass can crumble, and small fragments will damage the sensor. In other words, we still have to completely change the module.
• In conclusion, we note that for gluing new glass, you need to have certain skills, and therefore it is best to use 2-sided tape instead of glue.
