How to remove protective film With plastic windows

According to the manufacturer's recommendation, the protective tape from the plastic window should be removed, preferably within the first 10 days after installation. Subsequently, it will not be possible to easily remove the film, since the properties of the glue will begin to change under the influence of heat and sunlight.

To solve the problem, you can invite specialists from a cleaning company who will quickly and professionally clean the surface of the window from adhering film. But with certain skills, you can try to remove it yourself, using a special scraper for glass ceramics and a hair dryer. You can peel off the tape using technical alcohol or tape if you can tear it off piece by piece.

The purpose of the protective film on a plastic window is to protect the surface of the block from possible scratches and dirt. After delivery of the product, installation and completion of the slopes, the film must be removed.

It is best to do this right away, but this is not always possible. But it is necessary to remove even strongly stuck tape. There are several ways to try.

Heating the film with a hair dryer

This is one of the most simple methods removing unnecessary film. If you heat its surface with a hairdryer, soften the layer of old and dried glue, then it will be easy to pick up the edge of the tape and lift it at least a little. Then, direct a stream of hot air under the film and pull it little by little, gradually tearing it away from the window block. Thus, without breaks, you can remove an entire strip.

When working with a hair dryer, do not allow hot air to hit the glass - it may burst from the high temperature.

Mechanical cleaning with a scraper

If the film cannot be lifted because it immediately begins to tear and crumble, you should use scrapers to clean glass ceramics or to remove paint, you can also work with a universal one, but in all cases you should take a new blade, then the surface to be cleaned will be more even. It is also necessary to preheat the old tape each time with a construction or regular hairdryer in turbo mode; you can use a steam generator. Remains of glue and film can be easily removed with a scraper held at a minimal angle to the surface.

Using tape

Sometimes after cleaning there are stuck pieces that cannot be removed. In this case, wide tape will come in handy. First, you will need to degrease the profile surface with detergents or alcohol. It is better to use the hard side of the sponge and wash everything thoroughly.

Then you need to wipe the surface dry, stick tape on it and level it with a rag. After an hour it needs to be removed. Pieces of the protective film will remain stuck to its surface.

All attempts to remove stuck pieces with a blade or abrasive cleaning agents can lead to damage to the plastic profile. However small scratches can be removed with white Cosmofen brand glue, which is otherwise called liquid plastic. Sometimes the German cleaning agent FENOSOL S 10, which has a slight dissolving effect, can help. It is applied to a cotton napkin and wiped over the damaged surface. When using these drugs, you must follow the safety precautions and rules for working with these substances specified by the manufacturer.

Special adhesive removers

When the remaining film needs to be removed, and a hairdryer is not available, you should use products to remove adhesive residue. Universal American aerosol product WD-40, which contains white spirit, can help in this matter. The substance does not interact with plastic and removes stickers and dirt from glass.

Other substances have a more targeted application and are used to remove tape residues and adhesive stains from stickers. Among them is HG sticker remover - which completely removes stickers, self-adhesive tapes, oil and bitumen stains. As with all chemicals of this principle of action, you need to work with it very carefully and keep it away from children.

Using HG sticker remover is simple, just bend a small corner of the stuck film and drop a little liquid there. Leave it for a while, and then you can simply remove everything and wipe the area with a cloth.

“Solins”, “LAVEL OFF”, “Antiscotch” and others have the same ability to remove remnants of the adhesive layer.

Remaining glue stains on the profile can be removed using a cotton pad and white spirit. You can use a regular school eraser, but it will take a lot of time. And then you need to completely wash the window with warm soapy water.

Before applying any of these products to the front surface window profile, it is necessary to check its effect in a hidden area between the frames or near the seal. If the color of the frame has changed or yellowed, or the structure of its top layer has changed, then you should not use this product.

How to remove protective film with alcohol

When the film crumbles into small pieces that are almost impossible to tear off from the surface, you can use industrial or medical alcohol to remove them. To do this, you need a small spray bottle; the one that is used to moisten the leaves is also suitable. indoor plants. You need to fill a container with alcohol and spray it over the contaminated frame. After a few minutes, all that remains is to wipe the desired area with a hard sponge or brush. You should not use metal brushes or sponges for these purposes, as they will damage the plastic.

You need to spray alcohol carefully, do not allow splashes to get into your eyes. There should be no children or pets in the room at this time.

If the renovation in the apartment has not yet been completed, and the windows have already been installed, then in order to avoid future problems with removing the protective film, it is better to remove it immediately. And before the installation of slopes, plastering of walls, wallpapering and painting begins, it is better to seal the surface of the plastic with masking tape.

The listed methods for removing used protective film from PVC windows are the simplest and not too expensive. But if for some reason there is a lot on the windows various contaminants, you should not risk the appearance of these products; it is better to call specialists from a cleaning company.

The hot summer days are gone... Shining mirror shine Has the window of your room begun to bring trouble instead of life-giving coolness? Has your favorite ficus dropped its leaves? Did your favorite canary start to wake up and chirp just before lunch? And all because there was not enough light in the house! A miracle of technology - the thinnest sun protection film, which saved you from the oppressive heat in the summer, began to show its negative properties with the arrival of autumn.

Light transmission through a plastic window decreased by 20-30%. It's time to think about how to remove the film from plastic windows without damaging the PVC profile and without scratching the glass...

Methods for removing light protective film

The negative qualities of sunscreen films begin to manifest themselves in the autumn winter period. And they are connected with the fact that the light transmittance of these films is 90% - 5%. Manufacturers recommend removing the film from the plastic window for the winter. And they do this not to increase sales volumes, but to prevent complaints from consumers who, when buying and gluing reflective film, did not carefully read the instructions.

The vast majority of sun protection (mirror) films are currently glued to a plastic window using the “wet” method - using a soap solution. But the composition of the glue, in most cases, remains a trade secret of the manufacturer.

We can only state that any reputable manufacturer strives to ensure that the glue is of high quality and resistant to UV rays, precipitation, temperature changes and mechanical stress.

It is these properties of the glue that create insurmountable obstacles for some home craftsmen who have successfully coped with the problem of high-quality gluing of film when the time comes to get rid of it.

Of all the methods that have been invented, with the exception of contacting the manufacturer with the question: what solvent should you use for the sun protection film you produced to remove it?

And this information is usually placed on the packaging of films from reputable and trusted companies from the Netherlands, Germany or France.

90%+ of products from companies in the Southeast Asian region either do not indicate the brand of solvent at all, or place this information encrypted, in hieroglyphs that defy the Russian mind, in the list of technical characteristics.

Craftsmen have come up with 3 main ways to remove film:

• soaking;
• warming up;
• use of solvents.

Soaking reflective films

If the film is glued to the glass of a plastic window using aqueous solution with the addition of surfactants (surfactants), it is logical to assume that the glue used by the manufacturer is water-soluble.

The simplest would be old method soaking.

For this you will need:

• cotton or semi-synthetic fabric, which in size completely corresponds to the size of the window glass;
• spray;
• foam paint roller;
• basin for solution with surfactants;
• construction scraper with replaceable blades;
• plastic or rubber spatula.

Step 1

Over the summer, the film has time to dry out, and the structure of the polymer becomes fragile. It needs to be thoroughly soaked in water to remove it. Cut a piece of canvas 10-20 mm larger in length/width than the dimensions of the plastic window glass, so that it bends slightly onto the PVC profile of the window frames. Soak it in a solution with a surfactant. To do this, you can use any detergent, but the best one is dishwashing detergent - “Fairy”, “Sorti”, “Dosya”, “Kaplya”, etc. or window cleaner.

Step 2

Moisten the surface of the film with a solution containing a surfactant from a spray bottle and stick a wet cloth on it. Spray the fabric periodically to keep it moist. Take your time! The longer the film soaks on the plastic window, the easier it will be to remove it from the glass. Minimum exposure – 1 hour.

Step 3

Use your fingernail or a sharp object (toothpick, plastic spatula) to pry the film off top corner window and try to separate it from the glass by 10-20 mm. After this, moisten the separated area with a spray bottle so that the solution gets between the adhesive surface of the film and the glass. Leave for 5-10 minutes.

Step 4

It is better to do it with an assistant. Grab the peeled corner with your fingers and very slowly and smoothly, without any sudden effort, pull it towards you. If the film begins to peel off, you can clean the glass without any problems. You will be successful!

Holding the corner of the film with your fingers and your other hand, use a hard rubber (plastic) spatula to peel off a narrow strip along the entire upper edge of the window and moisten it again with a spray bottle.

Step 5

All further work will consist of you smoothly and evenly pulling the film towards you, trying to prevent it from tearing, and an assistant will moisten the surface of the glass at this time so that the soap solution gets between the film and the glass.

The main thing is not to rush. Intervals after moisturizing should be 5-10 minutes.

Step 6

If there are pieces of film that have not come off on the window, moisten them generously and remove them using a construction (office) scraper with replaceable blades. After the film is completely removed, the window is washed with a solution of window cleaner. You can add a few drops of ammonia solution to it ( ammonia) to add shine to the glass.

Removal with a hair dryer

All polymer coatings sensitive to temperature increases. When heated, they become more flexible and much easier to bend or separate from each other. Reflective films are made from heat-resistant polymers. So that during active heating in the Sun they do not peel off spontaneously. Therefore, their heating temperature should be quite high - 50-100°C.

An ordinary household hair dryer will not work for this (the overheating protection relay will work).

To clean the window you need to use a hair dryer. The film separation technology does not differ significantly from that when using a soap solution.

Step 1

Heat the entire surface of the window with the film glued evenly, holding the hairdryer at a distance of 100-150 mm from the surface. Do not hold the hair dryer in one area. Glass may burst due to overheating.

Step 2

Point the hairdryer at the corner of the film at the top edge of the window for 2-5 seconds.

Pick up the softened film with a spatula and separate it from the glass.

Step 3

Need help from an assistant. Evenly, holding the hairdryer 50-100 mm from the glass, move it along the film in horizontal plane. An assistant must keep the film taut while separating (pasting) it from the glass.

The main thing is not to overheat the film and glass; the film may begin to deform and stretch out in threads, and the glass may burst due to the high temperature.

Step 4

After removing the film, wash the glass.

Removal using solvents

All polymer films, including reflective ones, are sensitive to nitro solvents. Therefore, to remove them, you should never use liquids containing acetone or similar chemicals. Otherwise you risk dissolving polymer base, turning it into a viscous mass, leaving glue on the glass.

As a solvent for glue, it is necessary to use either the solvent recommended by the manufacturer, or select it experimentally by conducting a series of tests.

For testing, use pieces of film left over after repairs, or peel off a corner of the film on the window glass using one of the methods described above.

Important to remember! Working with solvents requires the mandatory use of respiratory protection - a protective respirator with cartridges for working with chemicals, or a gas mask.

Remove all plants and pets from the room (especially cold-blooded ones - fish, amphibians, reptiles)! Work without children!

Windows must be open when working!

The most suitable solvents for film removal are those based on petroleum distillation products - gasoline, naphtha, solvents:

• nefras C2;
• Z-646;
• toluene;
• ethylgasoline;
• orthoxynol;
• solvent, etc.

Or alcohol-based - isopropyl alcohol, formic alcohol, formaldehyde, etc.

All these solvents are toxic!

After peeling off a corner of the film, use a pipette to apply a few drops of solvent between the film and the glass. If the solvent is effective, a rainbow-colored spot should form between the film and the glass, and the film should separate from the glass without any effort.

Apply the solvent between the film and the glass using a pipette. The exposure between the application of the solvent and the film separation time is 1-3 minutes.

The process can be controlled visually by the formation of a rainbow layer between the film and glass.

Before starting work on inner surface PVC Profile Define PVC resistance window profile to the selected solvent. To do this, soak a piece of cotton wool in a solvent and apply it to the PVC profile. If after this there are cotton wool fibers left on the window profile, you cannot use such a solvent!

Apply solvent especially carefully along the edges of the film. He shouldn't get on rubber seals windows, otherwise they will melt! Immediately wipe off any solvent that gets on the rubber with a dry cloth.

You can only work with gasoline-resistant rubber gloves!

Instead of a conclusion

These are not tricky, time-tested, but very unreliable ways to remove reflective film from the glass of a plastic window. All of them require time and painstaking, leisurely work.

Owners of plastic windows are often faced with the question of how to wash the protective film. Of course, it is much easier to remove it immediately after installing the window, but often the owners do not peel it off immediately or completely forget about it.

However, the time comes when the protective material will have to be removed. Then the question arises: how to remove dried film from plastic windows?

Naturally, it is important not to damage the window during this process, and you also want to complete everything as quickly as possible and without extra effort. What can be done in this case? Effective methods exist, which means you can safely use them.

But in order to successfully remove the protective film, you must first understand the essence of the problem in more detail. Then it will be much easier to solve it.

Causes of hard film adhesion

Why do we need film on metal-plastic profiles? Companies, by gluing it, ensure the integrity of the product during transportation and installation. On the one hand, it is good that such protection is glued to plastic windows. However, how ordinary people then get rid of it? When the product is already in place and protective layer is no longer needed.

Very often, windows are changed during complete renovation apartments or houses. This means that after installation PVC window profiles, a thin film coating remains for some time until the repair is completed completely, and dries.

After a few weeks, the film adheres more strongly to the plastic and practically merges with it. Dealing with dried out protective material is no longer easy.

Why security tape sticks more over time:

1. Unscrupulous window manufacturers usually skimp on some nuances. Their range includes glue, which is used for gluing protective material. There is such an unusual pattern: the lower the quality of the glue used, the stronger it attaches the film to the window. In this case, there are only two options: either remove the film layer immediately after installation metal-plastic product, or choose the manufacturer more carefully.
2. The time of year, oddly enough, also greatly affects the adhesiveness of the protective tape. In winter and autumn, for example, the frame is cold, the glue seems to curl up and the adhesion of the film to the film is minimized. If it’s a warm season outside, the stickiness increases and it becomes difficult to clean the profile.
3. If you have a sunny side, then we can say with confidence that already a week after installing a PVC window, the film will stick strongly if it is not removed immediately. The fact is that under the influence of constant heating from the sun's rays, the protective tape seems to dissolve and combine with glue mixture and adheres strongly to plastic. And then it dries out. Therefore, draw your own conclusions, and it is better to immediately rip the tapes off the frames.

These are the main reasons why the protective film layer can be difficult to remove even a month after installation. The whole essence is hidden in the adhesive composition. This is what we need to fight against.

How to remove protective film from plastic windows correctly? There are several ways. Choose individually the one that is most suitable for you.

Mechanical disposal methods

There are only two such methods. These are the most effective and proven methods.

Let's take a closer look at them:

1. Using a scraper. If you have a question, how to remove duct tape, then a scraper will help. IN winter time Of course, it is better not to use this method, since the glue remains dense, and it will be difficult to scrape off the protective layer without damaging the plastic. But in the summer, this is the best option; the protective coating should be removed well and quickly. The scraper is able to effectively cope with melted adhesive composition on frames and double-glazed windows. Depending on the length of time the tape remains on the windows, it can be removed in different ways, in small parts or large pieces.
2. Stationery tape. How to peel off PVC film? Very simply, using tape. The bottom line is that, as already mentioned, the adhesive protective paper is very thin, so it can be difficult to remove with continuous tape. Here ordinary wide tape will come to the rescue. It is denser and therefore stronger than window tape, that's the whole point. All you need to do is simply stick the tape tightly over the film, and then peel it off along with it. Thin ribbons can be easily removed and remain on the strip of tape.

All other methods are based on chemical exposure. But there is also a heating method, which is also considered good and simple. However, it also has its own nuances.

Removal by heating

How to remove film from plastic windows? If you have a hair dryer at home, you can use it to quick removal old protective film from a metal-plastic window. You can also try using a household steam generator. The main idea is to melt the adhesive layer between the film and the surface of the window, due to which the tape will come off more freely.

The following points need to be taken into account:

• You shouldn’t heat it too much, as the ribbon may melt, which will only make the task more difficult;
• after warming up, you must first let the window cool down;
• do not rush, otherwise the tape will be removed unevenly;
• You can’t hold the hairdryer too close;
• hot air should not be directed towards plastic profile, and on the glass.

If you follow all the recommendations and carry out the procedure correctly, then tearing off the sticky protective paper will not be difficult. It will be enough to simply pry the edge of the tape with a knife or scraper, and then remove the coating in a continuous piece without interruption.

Chemical removal method

You can also remove film from plastic windows using chemicals. These removal methods are based protective coating with profiles, lie chemicals. They are able to dissolve sticky material, which will then come off easily, and then you can simply wash it.

So, you can use the following cleaning products:

• Schumann;
• Anti-scotch;
• Mellerud;
• LABEL OFF;
• composition RP-6;
• WD-40 composition.

All these products will come to the rescue in peeling off old stickers, tape and washing off adhesive stains from PVC windows, and will also help remove old paint. They are perfectly capable of scrubbing off protective tapes on profiles without damaging the plastic surface at all.

If after removing the film there are still traces of glue, they should be completely wiped off so that dust does not stick. You can use white spirit or acetone to remove them. And also try to remove stains with a stationery eraser.

Removing the sun protection layer

Another fairly common question that concerns not only plastic, but also wooden products, this is how to remove solar control film from a window? Is it even possible to tear it off? Yes, of course this is real. However, any kind of strong solvents are inappropriate to remove the film. How to clean the glass in this case? It will be enough an ordinary knife and soap solution, or you can use Schumanite.

It’s worth saying right away that removing sun protection will not be so easy. But if you put in some time and effort, everything will work out.

How to remove film from glass? It is advisable to slightly warm the surface of the glass with a hairdryer before starting work. Next, thoroughly wipe the window with soapy water and begin removing the coating. The glue will gradually dissolve, and when tearing off the protective canvas, you will have to carefully pry it off with a scraper.

Finally, the glass unit and frames are washed away from the solar control film store product for washing glass. If scratches are found on the plastic after the work has been done, then Cosmofen will come to the rescue. However, before using it, you should carefully study the instructions.

Here are some simple ways to clean the film on your windows. The main thing is to do everything slowly and carefully. Then the result will be excellent, and there will definitely be no traces or defects left.

According to the rules, after installing plastic windows, the protective film must be removed within 10 days. This is due to the fact that the film in direct contact with the frame is very thin and delicate, and under the influence of sunlight and high temperatures it is destroyed. As a result, we see the composition “tightly” stuck, and the longer it is not removed, the more it will dry out. Therefore, it is better to remove the protection in time.

How to remove film from plastic windows? What is needed to clean the surface and prevent the adhesive base from sticking even stronger? And what should you do if you couldn’t remove the protective film from the window in time? There are a number of ways to solve this problem.

How to remove solar control film from a window

If you decide to do everything that needs to be done in a timely manner, the film will be removed much easier. How to remove film from plastic windows without damaging the material? Use one of the following methods to solve the problem at home, without the help of specialists.

"Cosmofen"

This is a special solvent that can be purchased from a company that installs plastic windows. There are 3 types of “Cosmofen”, differing in the degree of impact: No. 5, No. 10 and No. 20.

The strongest is No. 5, and if used carelessly, you can “dissolve” not only the adhesive base, but also the plastic itself. Therefore, it is better to use the least aggressive composition.

During operation, follow the instructions for use, and removing the protective film will not be difficult.

Knife, blade or scraper

When using sharp objects, be careful not to damage the surface. The edge of the protection is pryed off with a knife or blade, and the remaining part is removed by hand. Remember, the less you use cutting accessories, the less damage there will be to the plastic.

After you remove the film from a plastic window, noticeable traces of glue may remain on the surface. You can wash them using a hard bristled sponge and any foaming product.

Construction hair dryer

How to remove sun protection film from a window using a hair dryer? Follow the basic rule: when removing the protection, direct the air stream only to the frame, without touching the double-glazed windows. Otherwise, the glass may not withstand temperature changes and cracks will appear on it.

The mechanism of action is simple - under the influence of heat, the adhesive base softens, and its removal will not take much effort. You can use a steam generator or a regular hairdryer in the same way. The latter is effective only in cases where the film has not had time to dry much.

Solvent or white spirit

Before using one of these products, test its effect on an inconspicuous area of ​​the surface. If the chemical does not harm the plastic, you can start working.

How to remove the protective film from plastic windows and clean the surface using solvent or white spirit? First, pry up the edge of the protection, and then apply the substance into the gap between it and the plastic. In this way, gradually clean the entire surface.

Paint remover RP6

You will need to apply the product to the surface in a thick layer and wait 7-10 minutes. During this time, you will notice that the remaining protection begins to “bubble”.

After this, put on gloves and glasses and remove the film from the plastic. Remains of the product and adhesive base can be washed with a concentrated soap solution.

Stiff brush and soap solution

This method is effective in cases where the window is located on the shady side. The adhesive base does not have time to heat up very much, and its adhesion to the plastic is not so strong.

Prepare a solution from warm water and soap and clean off any remaining protection using a stiff brush (not a metal one!).

Denatured alcohol

How to remove film from plastic windows with denatured alcohol? Pour the substance into a spray bottle and “irrigate” the surface evenly. After 3-5 minutes, pry the edge of the film with a knife and carefully remove it with your hands.

When working with chemicals, be sure to protect your hands with rubber gloves.

Detergent "Shumanit"

This chemical can be purchased at a hardware store. Clean plastic strictly following the instructions for use, as this substance is very strong.

After treatment, wash the area to be cleaned. clean water and wipe dry with a piece of soft cloth.

If, after removing the main part of the protection, small “islands” remain on the surface, take a regular eraser and clean the surface.

Why does the film dry out?

How to delete old film from plastic windows, if it has dried “tightly”? First you need to figure out why this happens.

How to remove old film from plastic windows if it has dried out

How to remove old solar control film from windows if it is stuck? You can use the following options:

• Contact specialists who have at their disposal special means, allowing you to solve the problem quickly.
• Use a special scraper designed for cleaning plastic and glass surfaces.
• Use a strong concentration of solvent, after testing it on an inconspicuous area of ​​the plastic.
• Use dish soap and a sharp knife. Moisten the surface with a soapy substance, and when it “soaks” a little, remove the protection with a knife.
• In some cases, chemicals used for cleaning can help remove the old protective film. kitchen stoves. The principle of action is the same as in the case of dish gel.

How to remove old film quickly and without much difficulty? Please note one nuance: in sunny weather, when the windows warm up well, it will be easier to remove it. If you do not want to wait for suitable weather, warm up the window with a hairdryer before starting work.

Glad to see everyone on my blog!

After installing plastic windows, not everyone immediately removes the film from them. But in vain!

More than once I had to observe in a recently built house nearby how the residents rubbed it with wet rags and tried to scrape it off with a scraper, since they did not immediately realize that they should have removed it immediately after purchase.

What can I say, because many people buy apartments after the film has had time to dry tightly.

Therefore, be vigilant, read useful tips about effective ways cleaning and test them immediately in practice.

On the protective films of profiles, manufacturers write that removing the film from metal-plastic window designs necessary immediately after installation work. But, for a number of reasons, this requirement is often neglected.

The protective coating protects the structure from contamination that inevitably arises during repairs or construction.

For example, the film can be useful when decorating slopes, external insulation of housing, and carrying out decorative work.

In such cases, the film's adhesive remains on the frames longer and hardens over time. This complicates the process of removing the film, and the glue itself sticks to the windows in the form of unaesthetic black spots.

How then to remove the film from plastic windows?

Helpful advice!

This problem can be solved in two stages, sequentially using mechanical and chemical methods.

The first will allow you to remove the film itself, while the second will deal directly with the glue.

Accordingly, to achieve the best effect, it is advisable to go through both stages. This approach will allow you to effectively get rid of the problem and avoid scratches on the windows.

So, the protective coating can be safely removed with three tools:

• scraper for cleaning glass-ceramic cookers;
• an industrial hair dryer (it is also acceptable to use a high-power household hair dryer);
• school eraser.

In the first case, you should carefully separate the film with the sharp edge of a scraper. Due to the fact that this device is designed for glass ceramics, the likelihood of scratches on the windows is quite low. But you should still be careful when working.

The second option is considered safer and more reliable. It is necessary to heat the sealed surface with hot air.

It is important not to overdo it so that the film does not melt and stick tightly to the structure. More warm covering removed in one confident movement. If necessary, the edge can be pryed off with any sharp object.

Removing film with an eraser, at first glance, seems to be a rather exotic method. In practice, this method will require quite a lot of effort from you, but the PVC profile will probably remain intact.

But to remove film from plastic windows, use one mechanical method not enough.

After physically peeling off the film window frames What remains is the glue, which is firmly adhered to the structure. If the composition has not had time to dry well, you can get by with an ordinary household rag and soapy water.

Use a well-moistened cloth to rub the contaminated areas vigorously. However, in some cases you will need more powerful tools. Thus, the chemicals COSMOFEN 10 or FENOSOL performed well. They are good because in addition to stubborn dirt they can also remove minor scratches.

You can also use Nanoflex P-12, an equipment cleaning product. It is worth mentioning that the listed methods for removing the protective coating are suitable for all elements of window structures. The adhesive composition in them, as a rule, is the same, which allows the use of the same products for working with frames, double-glazed windows, window sills, and fittings.

In conclusion, we note that before removing the film from plastic windows, you should definitely complete all construction works in the area of ​​the opening. This way you can maintain an attractive appearance structures for a long time.

Naturally, with the exception of those works after which it will not be possible to physically remove the film.

Do we remove the film if we didn’t do it right away?

The frames of metal-plastic windows are protected with a special film in order to protect them from dirt, scratches and other damage during transportation and installation.

Removing film from metal-plastic windows is extremely simple if done in a timely manner, i.e. immediately after the windows have been installed.

If for some reason you delay this, then removing the film can become a big problem. According to the instructions, the film must be removed within 10 days after installing metal-plastic windows.

If you increase given period until a month or two, then most likely nothing bad will happen. Then, when the film remains on the frames for 3 months or more, it will take a lot of effort to remove it.

Why does this discrepancy arise? It turns out that the protective film consists of two layers and is glued to the frames using a special glue. Under the influence of heat and solar radiation the thin inner layer of film decomposes and firmly adheres to the plastic.

Separating the surface layer of the film is not as difficult as the inner one.

Reasons that increase the adhesion of the film to the frame:

1. Action ultraviolet rays. Since the film on the windows located on the shady side of the building can be removed after a few months, then sunny side it will begin to soak into the frame in just a few days.
2. Glue quality. The lower the quality of the glue that holds the film, the more difficult it will be to tear it off. When installing inexpensive metal-plastic windows, the likelihood of encountering poor adhesive is higher.
3. Action of heat. If the windows are installed in winter, the film will begin to dry to the frame later. This will happen extremely quickly in the summer.

Finally, we will consider how to remove film from metal-plastic windows if it was not removed in a timely manner.

• Use a hair dryer. This the best remedy to remove film. The main thing is to direct it at the frame, but not at the glass unit, otherwise it has the possibility of bursting from the temperature difference. The film is heated by hot air, dissolves and is easily removed. The only problem is to find a hair dryer. Some try to use ordinary, in turbo mode. This can only be crowned with triumph when the film is not quite firmly adhered.
• Contact a cleaning company. The majority of such companies provide a similar service, and they have the devices required for this: a hair dryer, special scrapers and cleaners. And skill in solving similar difficulties.
• Using a professional cleaning scraper glass-ceramic plates. Such a scraper will not damage the plastic.
• Slowly, piece by piece, picking up the edge of the film with a thin knife, blade or scraper, and then tearing it off with your hands. Cutting devices should be used as little as possible, trying to separate the film with your fingers.
• Remaining glue can be washed off rough side sponges and detergent for bathrooms.
• A weak solvent. When using solvent, you must be extremely careful and first test on an inconspicuous area. The solvent has the ability to change the color of plastic frames.
• An eraser. An ordinary school eraser for erasing a pencil can help remove any remaining film.
• Rough though not wire brush and soap solution. The method is suitable for film on the shadow side.
• White spirit. Although it should not be applied on top, on pieces of film, but between the film and the plastic. To achieve the desired result, you need to pry up the edge of the film, pour white spirit into this place, wait a little and separate the film.
• "Cosmofenom". In companies installing metal-plastic windows, you can purchase a special product for cleaning plastics - “Cosmofen”. Based on the degree of activity of the active drug, “Cosmofen No. 5”, “Cosmofen No. 10” and “Cosmofen No. 20” are distinguished. No. 5 is the most powerful solvent; it dissolves plastic, so it must be used with great caution. In general, let's say 2 others. These are potent and unsafe for human well-being.

Often the film is not removed because the repairs are being delayed and you want to protect the window frames from paint, whitewash and other contaminants. This is a wrong approach, which will give rise to many more dilemmas. It is much better to remove the protective film, and if protection is needed, stick it on the frames masking tape. It won't be difficult to remove it at all.

Removing protective film from PVC windows

Very often we hear questions of this kind:

“A year ago, plastic windows were installed at the company ****. All this time, the apartment was undergoing renovations, and my husband and I lived with relatives.

Now, after completing the repair, we discovered that the protective film that is glued to the plastic does not come off. That is, the film that was inside the apartment came off normally, but on the street side it holds tightly.

How can I try to remove the film from the window? maybe there is some remedy?

I have to disappoint you, I don’t know any means that can help you with 100% probability. After installing the window, the protective film must be immediately removed, otherwise in the sun under the influence of ultraviolet radiation it is destroyed and fused into the plastic.

Note!

The protective film must be removed immediately, otherwise the sun will destroy it and melt into the plastic.

Manufacturers of plastic windows even write warnings about this on the film, but usually in an overseas language. In our practice, there was a case when we installed windows for the entire house for customers, and the profile from which the windows were welded lay for a long time on the street under the sun.

We were unable to remove the film from these windows, and the problem arose, of course, after all the windows were installed. As a result, we had to completely replace all the windows with new ones.

But sometimes, special cleaning products can help remove the film. We sell Cosmofen plastic cleaner. A very serious thing I must say. Distributed specifically for window companies.

There are 3 brands of Cosmofen: Cosmofen No. 5, Cosmofen No. 10 and Cosmofen No. 20, they differ in the degree of dissolution of PVC plastic.

So Cosmofen No. 20 does not dissolve plastic at all, Cosmofen No. 10 is a weak solvent for PVC and Cosmofen No. 5 is the strongest solvent.

I think that if Cosmofen does not help you, then nothing will help you. The only way out is either to change the windows, or to spit and forget, thank God the film is on the street and is not visible from the apartment.

How to remove film from windows after installing them

When installing plastic windows, always remember that you must remove the protective film that covers the profile for safety purposes immediately after the windows are in place and that’s it. Finishing work finished.

However, real situations indicate that consumers often order PVC windows from one company such famous brands such as “KVE”, “PROPLEX”, “Veka” or the famous “Rehau”, and their installation is carried out independently or with the help of other contractor companies.

In such situations, everyone completely forgets to remove the notorious protective film on the profile, which, under the influence of sunlight, sticks to the window so much that it is almost impossible to remove.

If something happens, claims can be made against her regarding the quality of the work performed, and her employees will have to worry about removing the film from outside profile.

The film on windows prevents scratches, both during their installation and during installation. Experts in this field recommend getting rid of such harmful film within 10 days after windows are exposed to the sun.

If time is lost and the protective layer has not been removed, do not be arbitrary, but listen to useful tips, proven by time and practice. Many people make the gravest mistake of trying to remove the film with a solvent. This way, the film will remain on the windows, and the profile may be hopelessly damaged.

Proceed with extreme caution, as strong heat may damage the entire profile.

No less effective means when removing the film from the window, you will also use a special scraper used during cleaning hobs and ceramic tiles.

You can safely work with a scraper, because it does not damage the plastic surface.

Try to very carefully pick up the edges of the stuck film with a scraper and remove it from the window piece by piece. If possible, work only with your fingers, since even a safe scraper can leave scratches on the PVC profile.

When finished, thoroughly wipe off any remaining glue with warm soapy water. If the glue cannot be cleaned with soapy water, then use the special cleaner “Cosmofen 10”.

The important thing is that it not only removes the remaining adhesive from the film, but also largely masks the small cracks that have formed. An ordinary eraser from the school desk helps a lot; it rolls off the remaining glue perfectly and helps achieve the desired results.

All of the above tips are time-tested and give positive results when handling all equipment with care.

But if you enter into an agreement for the production, supply and installation of plastic windows with one organization (which is the best option), then make sure that they worry about removing the film from the window.
