How to remove old protective film from plastic windows. How to remove protective film from plastic windows? Effective removal methods How to remove old film from plastic

The hot summer days have passed... The window of your room shining with a mirror shine has begun to bring troubles 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 prejudice to PVC profile and at the same time, do not scratch 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 region South-East Asia, 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 an aqueous solution with the addition of surfactants (surfactants), then 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 that fits perfectly in size 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. For this you can use any detergent, but the best thing is dishwashing detergent - “Fairy”, “Sorti”, “Dosya”, “Drop”, 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 soap solution got 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 complete removal Window films are 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 clear the window you need to use construction 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 a 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 the inner surface of the PVC profile, determine the resistance of the PVC 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. It should not get on the rubber window seals, 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.

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 on effective cleaning methods and immediately test them in practice.

On the protective films of profiles, manufacturers write that removing the film from metal-plastic windows constructions are necessary immediately after the work on their installation. 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 Designed for glass ceramics, the likelihood of scratches on 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 physical department The film leaves glue on the window frames, 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's worth mentioning that listed methods withdrawals protective coating 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 have delayed this, then removing the film may become 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, thin inner layer The 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. Once the film is on the windows located on shadow side buildings 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 scraper for cleaning glass-ceramic hobs. 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 bathroom cleaner.
• 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 that install metal-plastic windows, you can purchase a special product for cleaning plastic – “Cosmofen”. Based on the degree of activity active drug There are “Cosmofen No. 5”, “Cosmofen No. 10” and “Cosmofen No. 20”. 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's much better to remove 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 there for a long time outside in 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 doesn’t help you, then nothing will. 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 of such well-known brands as “KBE”, “PROPLEX”, “Veka” or the famous “Rehau”, and install them themselves 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 sun rays It 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 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 significantly masks the resulting small cracks. From available means, a regular eraser with school desk, it perfectly rolls off glue residues and helps achieve the desired results.

All of the above tips are time-tested and give positive results if you handle all devices carefully.

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.

Not everyone knows that after installing new plastic windows, you need to remove the protective film in a timely manner. It is usually advised to do this within 10 days. If removal is delayed, the protective coating will stick to the glass. Getting rid of old film is not easy. It is necessary to use only proven removal methods, otherwise the glass may become covered with cracks and scratches. You should start cleaning as quickly as possible so that the film does not dry out even more.

The film dries on the windows and is difficult to remove for several reasons:

1. Exposure to ultraviolet radiation. If the windows are on the sunny side, then the protective coating should be removed as soon as possible. If you miss the deadline, it will stick firmly to the surface.
2. Heating. If the window becomes hot due to sunlight or heating devices, then the film dries to the glass very quickly. To get rid of it without a trace, you will have to try.
3. Poor quality glue. If cheap glue was used to make the film, it will soon dry to the window. This could even happen ahead of the attack the deadline for its removal.

Regardless of the reasons for drying, the film must be disposed of. After all, it spoils the appearance of plastic windows.

Removal methods

It is possible to remove old coating from glass at home. Even if it has managed to stick strongly to the window, you can try to fix it.

But to do this, you should choose proven means and methods that will not harm the glass surface.

Mechanical impact

The easiest way to get rid of dried film is mechanical action. To do this, pry its edge with a knife or blade and try to tear it off with your hands as much as possible. most dried coating.

This method is dangerous because it may leave noticeable scratches on the glass. Therefore, you need to act very carefully and do not use metal scrapers. It is advisable to minimize the contact of sharp objects with the window.

Hairdryer

If the protective coating sticks strongly, you can use a hair dryer. It should be used carefully - there should be no sources of fire or flammable objects in the room.

Algorithm of actions:

• direct a stream of hot air at plastic frame or window sill, trying not to get on the glass;
• When the film heats up, you need to carefully pry off its edge with a knife and peel it off manually.

It is important not to direct air directly onto the glass units. Otherwise, the glass will crack due to temperature changes.

If it is not possible to use an industrial hair dryer, you can use a steam generator or a regular hair dryer. However, they will only be effective if the film has recently adhered.

White Spirit

A powerful product that helps remove even long-dried film is white spirit.

Mode of application:

• pry off the edge of the dried protective coating;
• apply white spirit into the gap between it and the window;
• Gradually remove film from the entire surface.

This product must be used very carefully, as the solvent can damage the surface of the window. Therefore, before use, it is necessary to test its effect on an inconspicuous area of ​​the glass unit.

Alcohol

You can also remove old film from plastic windows using alcohol. To do this you need:

• take denatured alcohol;
• using a spray bottle, spray it onto the old coating;
• leave for 5 minutes;
• pry up the edge of the film and tear it off with your hands.

While working, you should protect your hands with rubber gloves.

Ready-made products

You can also use it to remove old coating. special means. They are able to effectively and quickly clean plastic windows.

1. Cosmofen.

Companies that install plastic windows often sell a special solvent, Cosmofen.

There are three variants of this composition: No. 5, No. 10 and No. 20. They differ in the strength of their impact. The most aggressive is No. 5.

Therefore, it is advisable to use No. 20 or No. 10. Otherwise, you can dissolve not only the film, but also the glass unit itself.

2. Paint remover RP 6.

You can purchase paint remover - RP 6.

Instructions for use:

• apply the product in a thick layer to the surface to be cleaned;
• wait 10 minutes;
• the coating should begin to bubble;
• After the allotted time has passed, the softened film should be removed.

When using this method, it is necessary to protect your hands with thick rubber gloves, and your eyes with special glasses.

3. Schumann.

In shops household chemicals you can find the Schumanite detergent. They need to process the glass and wait a certain time specified in the instructions. Then wash the window clean water and wipe it dry.

This product is very caustic and should be used with extreme caution.

Window cleaning

After removing the film, traces of glue will remain on the glass. You can wash off the residue using this method:

• prepare a concentrated soap solution by dissolving the shavings laundry soap in warm water;
• moisten a rag with the resulting solution;
• wipe the window, not forgetting the edges and corners.

You can also wipe off dirt with newspaper. After cleaning, the glass is wiped dry.

It is advisable to remove film from plastic windows immediately after installation. However, if for some reason the protective coating has dried to the glass, it is necessary to begin solving the problem as quickly as possible using proven means.

If the protective film on metal-plastic windows is not removed in a timely manner, it can stick very strongly to the plastic profile and will be extremely difficult to remove. Therefore, it is necessary to get rid of the protective films that cover the profiles of new metal-plastic windows. But what to do if the film is already “tightly” stuck? Let's look at several ways how remove film from plastic window.

The following recommendations will help you remove protective film not only from the window frame, but also from window sills and ebbs. First of all, you need to pay attention to the fact that when removing the old film, another problem may arise - the need to clean the profile from the adhesive with which the protective coating was glued.

There are two ways to remove film: chemical and mechanical.

Let's look at how to remove film from a plastic window mechanically. This option will require a special scraper used to clean glass ceramics, and good cleaner(eg COSMOFEN 10). First, the film is removed with a scraper, and the remaining adhesive is removed with cleaner or solvent R-12.

There are also several other ways to mechanically remove film and adhesive residues from window profiles, low tides and window sills. The second option is to use an industrial hair dryer and COSMOFEN 10 cleaner.

With this method of removing the film, first heat it with a hairdryer as much as possible and quickly pry up the edge stationery knife. It is necessary to tear the film off the surface gradually, but without stopping, otherwise it will tear and you will have to pry up the edge again. We remove traces of the adhesive base with a solvent or cleaner. If you have a steam generator, it is better to use it instead of a hair dryer. It will be faster this way.

You can also remove the film from a plastic window using chemicals. The first method is the use of technical alcohol and COSMOFEN cleaner. To apply alcohol to the surface of the film, you will need a regular sprayer for indoor plants.

After spraying the denatured alcohol, the film should soak for a couple of minutes. After this time, pry up the edge of the film and slowly pull it out. We repeat the procedure until the protective coating is completely removed. As in previous options, remove any remaining glue using a cleaner.

Is it possible to remove film from a plastic window using detergents? As practice has shown, the Schumanit detergent has proven itself very well in this regard. This remedy is quite strong, so you need to work with it very carefully. But in order to save yourself the extra hassle of removing the protective film, you need to remove it in time (immediately after the windows are in place and all finishing work is completed) and not wait until it sticks firmly to the window.

Detergent "Shumanit"

Among unusual ways To remove the protective coating on the profiles of new metal-plastic windows, use a rubber band and white spirit. Some craftsmen can remove the film even with a simple eraser, and glue residues, according to some, can be easily removed with white spirit. But in order not to check all the methods without practice, seek help from specialists. After all, they know exactly how to quickly and correctly remove the tightly stuck protective film from your new windows.

Where can I find a film removal specialist?

Company for the production and installation of metal-plastic windows and doors " Open Windows» offers its clients a full range of services, starting from the design stage metal-plastic structures, and until final installation. If necessary, our specialists can remove the protective film from your windows immediately after installation is complete.

How to remove film from plastic windows - a problem that arises when moving to new apartment, and during the renovation of an already inhabited living space. Often the owners come to their senses after completing the transformation - in this case the window has to be cleaned of pieces stuck to window frame. Having managed to remove them, the apartment owners are forced to struggle with sticky glue.

Some people resort to various detergents, one way or another, but in any case it is very difficult to cope with the problem.

It is worth noting, first of all, that the most reliable approach to ensuring a clean window is to remove the film immediately after installation plastic construction. If you lose time, you will have to deal with a thoroughly dried coating, which is quite difficult to remove.

Readers are given the opportunity to familiarize themselves with several methods for removing film. However, to get a truly clean window, you need to be prepared to remove the adhesive.

So, to clean the window from film and glue, you need to use one of two main ways to solve this problem. As alternative option– for greater efficiency, they often resort to a combination of these technologies.

The main methods allowing are presented the following options:

• mechanical;
• chemical

The mechanical option, in turn, implies several of the most effective varieties.

Clean windows from old film can be done using a special scraper, which is traditionally used when processing hobs or their glass-ceramic analogues.

You can remove glue residues and get rid of minor scratches by using cleaners such as FENOSOL and COSMOFEN 10. If these products are not available, it is recommended to use some acrylic solvent. As practice shows, it is convenient to finally clean windows from old solar control film using P-12.

The next method, which allows you to remove the protective coating and all its traces, is based on the use of industrial. In the absence of one, a powerful one is acceptable home hair dryer. The effectiveness of the technology is based on heating, which greatly facilitates film removal.

Heat film coating, it needs to be pryed off with a sharp stationery knife. The technique allows you to easily and quickly remove the film. To deal with glue residue, you need to use the first method.

Many users successfully achieve their desired goal using a steam generator. An unusual, but, according to reviews, quite effective method of erasing the film with a stationery eraser. To combat residual marks, you can choose white spirit or one of the mentioned cleaners.

In the pursuit of purity, diligence often turns sideways - new and not always solvable problems. Particular care must be taken when manipulating the scraper.

The fact is that even the safest scraper can leave quite noticeable scratches on the surface of the PVC profile. To avoid such an unpleasant side effect, it is best to remove the peeled film with your fingers.

Methods are no less in demand chemical cleaning. As a container used to solve the problem, you can use a regular water spray. Denatured alcohol is poured into it.

Then the product is applied to the surface, and after a few minutes you can begin to remove the protective coating. To simplify the work, you can pry it off with a stationery knife.

When solving the problem of how to remove film from plastic windows, you should pay attention to the “Shumanit” detergent (manufactured by the Buggy company, Israel).

The glass unit can be easily cleaned with a paint remover: RP 6. It is applied liberally to the surface to be treated. After ten minutes, the protective tape begins to swell literally before our eyes.

Before you begin the actual cleansing, be sure to wear gloves and goggles. When washing off glue and alkali residues, use soapy water.

Do not fight with the protective tape by using solvent. As a result of the efforts, the film will remain in its place, and side effect the profile will become hopelessly damaged.

Having completed the main part of the task - choosing how to remove the old sun protection film and using the most attractive method for yourself, you need to finish the job by washing the windows, which will require some time and attention.

It is best to resort to one of the following two proven methods - to wash with:

• paper, spray, rags;
• sponges, screeds.

First way

You can resort to it only if the surface is not very dirty.

The “working tools” in this situation will be:

• paper napkins;
• water container;
• product with a spray nozzle;
• cotton fabric.
