How to clean foam from plastic. How can you wipe off the remnants of mounting foam from different coatings. Stone, concrete, metal surface

Currently, polyurethane foam is one of the most popular building materials. And this is not surprising. After all, it is mounting foam that is used today both as a sealant, and as glue, and as a sound or heat insulator.

Most of both outdoor and indoor construction works directly related to its use. These are works related to the installation of doors or windows, with the insulation of houses, cladding them with siding, and works involving the laying of pipes.

But, as it turned out, such a multifunctional building material also has one small but very serious drawback: it adheres equally strongly to any material. Therefore, it is not at all easy to remove after hitting unwanted places. Such a nuisance can happen even with a professional in his field. And what can we say about the one who did the repair for the first time?

Ways to wash dried mounting foam

In fairness, it should be noted that a small drop of mounting foam can deliver a lot of unpleasant minutes to a professional. The same one who never worked with it building material, may not imagine how difficult it will be to get rid of even a small speck of mounting foam, because this material clings so tenaciously to any surface.

It cannot be washed off under running water, rather, you can get the opposite effect, because the foam expands and hardens under the influence of water. Little hope can be placed on some of our usual solvents or cleaners. For example, white spirit will not cope with polyurethane foam.

So is it really all that hopeless?

How to wash foam off your hands

How do you wash it off mounting foam that got on the skin of the hands? Of course, it will be much easier to remove a fresh stain using a damp cloth or some kind of cloth.

Some use some kind of skin-friendly solvent. If the foam is still frozen, then, first of all, you should know that this material does not contain any harmful substances, so you should not worry in this direction.

As for the aesthetic side of the issue, experienced builders most often use one proven folk method in this case.

Before you start removing the mounting foam that got on your hands, you should hold your hands in the solution for some time, approximately 5 minutes. table salt. After that, you need to take a regular pumice stone and gently scrape the problem area. So, the desired effect is achieved: hands are clean. Now you should lubricate them with a moisturizing hand cream.

If you still haven’t been able to completely clean your hands, do not worry. It will take quite a bit of time and the foam spots will disappear on their own.

How to clean plastic, linoleum and wood

It often happens that the mounting foam accidentally got not only on the hands, but also on the nearby surfaces made of plastic, linoleum or wood. If the foam stain is still quite fresh, then it can be removed from plastic or glass surfaces using a scraper that would not damage this surface, would not leave scratches on it. After that, using a hard sponge or cloth, the surface is cleaned again.

Some prefer to use a cleaner instead of a cloth. However, it should first be checked on the most inconspicuous area of ​​the same surface. Most often, acetone or agents such as solvent 646, Isofoam r621, Kosmofen, Macroflex wash are used.

But the foam that was not noticed immediately, and it has already hardened, will be more problematic to clean. Will have to be patient.

Some builders recommend that you first cut off the frozen stain with a blade as close to the surface as possible, and then try to soak it with a solvent and rub it with a fairly hard sponge. It is best to use SOUDAL PU Remover, which is designed to remove foam that has already hardened.

To remove mounting foam from more delicate surfaces, such as plastic, wood, linoleum, do not use those solvents that are considered aggressive. Some recommend using dimexide in this case. It's famous medicinal product, it is sold in any pharmacy. Moreover, it is quite inexpensive, almost a penny.

The existing stain is well moistened and left for several minutes, and then it is removed with a cloth, sponge or even a cotton swab.

If mounting foam has got on plastic windows, then the easiest way to get rid of it is to remove it with an oil solution.

Ordinary sunflower oil is applied for half an hour to the contaminated area, and then cleaned with intensive movements using a regular dishwashing sponge.

Remove hardened foam from clothes

The issue is much more difficult to solve if the mounting foam has got on the fabric or on the clothes. Whether it can be washed off or not will largely depend on the structure of the fabric itself.

It is almost impossible to clean knitted fabrics or knitwear. Foam stains can be removed from denim and leather goods using mineral spirits.

How to clean from glass or metal doors

In some cases, you can get rid of the frozen foam only with the help of a simple mechanical rubbing of the surface with a small piece of plastic. This is how it is recommended to clean a metal door or battery painted with enamel from mounting foam.

Foam stains can be removed from a glass surface in several ways. Some builders scrape it off with a knife or blade, while others prefer the use of a cleaner. Using a plastic scraper, carefully remove the stain from the foam that got on the car.

As you can see, in order to remove stains from mounting foam from various surfaces, you will have to make a lot of effort, and sometimes additional material costs will be required. At the same time, there are cases when it is not possible to achieve the expected effect. Therefore, it would be more correct to prevent the development of this situation and try to protect yourself as much as possible from the ingress of mounting foam on surfaces for which it was absolutely not intended.

  2. Now you need to process the surface itself.

Surface cleaners

Remember that there is no single option for every surface.

If the surface is made of stone, concrete, metal, then you can wash the mounting foam using acetone, aggressive chemicals.

If the surface is made of glass or plastic, "Dimexide" will help wipe the mounting foam.


Dimexide is a topical drug that you can find at any pharmacy.

An alternative to "Dimexide" will be sunflower oil, which should be applied for half an hour, and then removed with a damp cloth.

Hello dear readers! One of the most unpleasant moments in the repair is the dirt and dirt associated with this process. a large number of construction waste. Fortunately, these problems are quite easy to deal with: take out the remnants of building materials and wash off the dirt.

But often there are quite specific problems. For example, stains from paint, glue, silicone grease or foam. Here you can not do without special knowledge. Therefore, in this article we will analyze how to wipe mounting foam from any surface.

Why is foam so hard to remove?

In order to understand how to effectively scrub the foam, you need to understand its properties. This sealant has amazing holding, heat and sound insulation properties, and at the same time it is easy and convenient to use.

Compressed foam, leaving the can through the gun, increases several times. At the same time, it is saturated with many tiny bubbles that collapse and securely adhere it to the base. There is a process of adhesion - the penetration of one substance into another at the molecular level.

It turns out that as soon as the foam sealant touches any surface, it immediately firmly penetrates into its structure. And even if you did a good job in eliminating the surplus, and no traces are visible, know that some part of the composition still remains.

It is also worth considering that the stronger the object is moistened, the stronger the foam “sits” on it. That is why it is so difficult to remove the product from the hands, and it becomes obvious that trying to wash a fresh mark with water is a bad idea.

The conclusion suggests itself that it is better to play it safe and prevent pollution with polyurethane foam. To do this, before starting, during and after work, it is desirable to take the following measures:

  • remove all valuable items and furniture from the room, or at least cover it with a film;
  • grease with a greasy cream or petroleum jelly those areas that cannot be protected otherwise - for example, a window frame or a door leaf;
  • for work, wear the most closed clothes, be sure to wear a hat and gloves - and the uniform should consist of those things that you don’t mind throwing away later;
  • when buying a cylinder with a substance, immediately buy a cleaner or stock up on a solvent and Dimexide - they will certainly come in handy;
  • after foaming, especially large spaces, avoid drafts - they can “blow out” the sealant that has not yet cured.

Sealant removal methods

Before using any cleaner, first test it on a small, inconspicuous square and wait a while. If there is no change in the material, then the mixture can be applied.

Chemicals

Special cleaners- they are usually produced by the same manufacturers as building foam. It is noticed that the most effective means for removing contaminants from one line. Just be sure to read the label, which clearly states on which surfaces it is allowed to use. And strictly follow the instructions.

Solvents- this group includes "Acetone", White Spirit, "Solvent 646" and similar substances. They are effective for fresh tracks.

Dimexide – pharmacy drug which is worth every penny. It destroys the structure of polyurethane foam and allows you to remove it. It is quite aggressive, so gloves must be worn when working.

Vegetable oil- softens a thin layer of foam, so that it can be wiped off with a rag or spatula.

Vinegar- effective against fresh pollution.

Water- despite the fact that it is not worth moistening the newly applied composition, it will be an excellent assistant to soften the hardened layer.

Mechanical impact

Residue cleanup- occurs with a knife, scrapers, spatulas and similar tools. As a rule, such an impact is not enough, and some methods have to be used to soften and dissolve the polyurethane foam. However, pre-cleaning will help speed up the process significantly.

Grinding- this method is used when it is necessary to remove the stain from some materials. For example, it is easier to quickly rub a concrete floor with sandpaper than to torture it with chemicals for a long time and to no avail. Also, a similar technique is used if chemistry has not helped.

How to wipe the foam from various surfaces

For some materials, it will be preferable to remove the foam sealant immediately, not yet hardened, while others are better cleaned from already dried.

So, it is necessary to immediately clean the polyurethane foam from the skin and rough bases. It is better to remove the dried substance from plastic, glass and metal.

Leather

The person who performs the foaming may inadvertently get their hands dirty. And with not very skillful handling, some part can even get on the face.

The good news is that the foam is absolutely non-toxic and does not cause any harm to health. Therefore, if it does not bother you, then wait a few days until it “peels off” itself.

If you react quickly, then it is easy to wash the product with any solvent or acetone. You can try to remove the contamination with a 3% vinegar solution, alcohol or gasoline.

When the composition has already dried up, it becomes difficult to wash it. It will take a lot of effort and time. First, steam your hands hot water(at least 30 minutes), and then apply a rich cream on them with a rich layer.

To enhance the effect, table salt can be added to the solution, and instead of a cream, it is permissible to use vegetable oil.

Pumice stone is required to carefully clean off the pieces from the steamed skin. It is permissible to pry off some particles with a fingernail. At the end of the procedure, lubricate your hands again with cream to soothe irritated skin.

clothing

It will not work to remove the montage from clothes without a trace. In any case, either a darkening will remain, or in this place the fabric will brighten and fade. Therefore, if you intend to clean an accidentally soiled weekend outfit, then be prepared that now it will be appropriate to wear it only in the country.

Getting rid of the stain consists of several stages.

  1. With a knife or scissors, try to get rid of most of the foam cap.
  2. Apply purified gasoline, acetone or white spirit to the affected area. Leave it like this for 15-20 minutes.
  3. Try to wipe off the remains with a brush or the hard side of a sponge.
  4. If it doesn’t help, then make a compress with Dimexide. The drug should be poured onto a rag and applied to the dirty fragment. Leave for half an hour.
  5. Finally, wash the garment with stain remover and laundry detergent.

Just keep in mind that such processing destroys the fabric structure, so a hole may soon appear in this place. And synthetic fabrics can even “melt” even during the procedure.

If the affected area is small, then you can try to freeze the item in the freezer for an hour. After this time, pieces of sealant must be carefully scraped off. All that's left is to wash the clothes.

Plastic and glass

The cleaning problem often occurs during installation plastic windows. The window opening is treated with polyurethane foam around the entire perimeter, so drops of the substance also fall on the structure itself.

In order to erase stains from plastic windows, you need to wait for solidification and then simply scrape off the composition with a piece of wood or a plastic spatula. Also, to dissolve the mass, a reception with Dimexide is suitable.

You can use vegetable oil: apply it for 30-40 minutes and then remove the residue with a spatula or sponge.

Do not treat with solvent as it may leave marks on the PVC construction.

In the same way, the montage is removed from the glass.

Metal

Sealant is also used when installing input and interior doors. The first ones are usually made of metal, so when eliminating the foam, you will have to take into account some features of the material: it will not tolerate aggressive components and strong mechanical stress, so you should act as delicately as possible.

First of all, cut off metal door protruding hat. Then, with a sponge soaked in oil, you need to smear the problem area. After 30 minutes, lightly wipe the soiled area with the same sponge, removing the dirt. Finally, the door must be washed with soap to get rid of the greasy imprint.

Wood: raw, lacquered and painted

Doors and window frames can be made from wood. It is not excluded that drops of the product will get on wooden furniture located in the room. In this case, special attention should be paid to the top layer of the object, since it can be varnished or painted.

On unpainted and untreated wooden objects, it is allowed to use Dimexide.

Lacquered coatings require very careful handling, they are easy to damage and hopelessly spoil. Any solvents and "Dimexide" are categorically not suitable.

Watch the video about the use of a pharmacy drug.

Your dexterity and attentiveness will help here. You should catch the moment when the foam is no longer dirty, but has not yet turned into a solid mass. Having picked up the edge, it will be possible to simply remove the pollution by slightly pulling it up.

On already hardened sealant for varnished and painted objects, you can try a saline solution: for 1 glass of water, 1 tbsp. l. salt. Treat the affected area with the mixture and wait 5 minutes, and then remove the pieces of foam with a damp sponge.

In some cases, the only way out of the situation is grinding with sandpaper. In this case, after work, you will have to re-coat the item with varnish or paint.

Floor coverings

Most often, the floor suffers from excess foam. It is on him that the main attack falls in case of inaccurate handling. Before you rush to wipe off imperfections, you need to choose a method that is right for your coating.

  • Linoleum, laminate and parquet - first remove the excess with a sharp object and apply a compress with Dimexide to the dried polyurethane foam for 15 minutes. After this time, the treated area should be washed with soap. It is acceptable to use a cleaner (but not acetone - it leaves matte marks).

For parquet, the use of solvents on a “fresh” stain is allowed.

  • Carpet - after the composition has hardened, it is necessary to put a damp rag on the damaged area for 3-4 hours. After softening, clean the pieces with a brush.

Conclusion

There are no unsolvable problems. Of course, there is little pleasure in removing the mounting foam, because it will take a lot of effort. And the result is not guaranteed. But if such a situation has arisen, then it is worth trying to cope with it with minimal consequences.

It is best not to lead to trouble and carry out simple preventive measures that will save both property and nerves.

Have you ever had curiosities with polyurethane foam? How do you get rid of pollution?

When installing a door, window or other construction work, you cannot do without the use of mounting foam. It's popular in repair work the tool very effectively and reliably fastens various building elements, but it can be quite difficult to remove the foam remaining after construction, especially when it comes to goes already about hardened material. Even if all measures were taken in advance to protect against sealant, its particles can remain anywhere - on the floor, walls, doors, windows, clothes and hands. The question arises - how and how to wash mounting foam at home?

How to remove fresh stains of sealant from the surface of the door, window, floor

Fresh polyurethane foam can be removed best. It is easier to remove excess residue “in hot pursuit” than to wipe off already dried material. There is various ways removal of fresh stains:

For a metal door, the process of removing foam is somewhat simpler than with a wooden one. If for cleaning wooden door various solvents were used, then immediately after wiping, wash this area with soapy water so that the aggressive substances of the solvent do not damage the paintwork.

Also, with the help of solvents, you can clean mounting foam from clothes. If everything is done quickly, the fabric will not be damaged. After cleaning, clothes should be washed with plenty of washing powder.

How to wash mounting foam from hands

In order to avoid such questions as cleaning the mounting foam from the hands, it is better that during the construction work associated with the use of this tool, the hands were in thick leather gloves. If, nevertheless, it was not possible to avoid getting the sealant on your hands, then you can remove it using the following means:

  • Medical alcohol
  • Petrol
  • 3% vinegar solution
  • Acetone.

It is necessary to moisten a regular cotton swab with one of these products and gently wipe the skin of the hands. Then hands should be washed well running water using liquid soap and rub with baby cream.

There are other methods for removing sealant from hands.

  • The use of table salt. Pour into a small bowl warm water, add a teaspoon of salt, lower your hands and hold them a little in the saline solution.
  • Soapy water is suitable for fresh stains on the hands. Hands are dipped into a warm soapy solution; for a faster effect, the remaining foam can be wiped off with a sponge or washcloth.
  • Heated vegetable oil. The oil needs to be slightly warmed up and rub it with areas with sealant residues. Then cover the areas stained with foam a small amount washing powder, lather it up and rinse all the solution off your hands with plenty of water.

How to remove dried mounting foam from various surfaces

It is rather problematic to completely remove already hardened and dried foam from the surface the first time. The procedure for removing old stains will have to be repeated several times. From a metal, glass or stone surface, cleaning from lumps and stains is easier than from other materials. In these cases, there are also methods that will help solve the problem partially or completely.


Whatever means you have to use to remove the remnants of the sealant - this is a tedious task and not always effective, as we would like. Experienced builders use a protective film during the repair process and work in gloves and special clothing designed for construction work.

Hi friends. In the life, probably, every master had moments of panic associated with polyurethane foam. In working with her, special care is needed, but often even experienced guys have situations when she gets to where she should not be. This is especially true for door and window installers. Foam can get on the door frame, on a brand new window sill, it happens that on the laminate and even furniture. And to wash this creature - oh, how hard. There were times when the craftsmen had to buy back damaged items, just because they did not know what we are about to tell you. Secret life hacks, guys - how to wash mounting foam.

If you thought ahead with your head, you could stock up on special cleaners for polyurethane foam. They are not uncommon and are sold in any normal building store in cylinders with the same valve as professional foam cylinders. In general, they are needed to be put in a gun. But we conjure you - do not flush the gun with a cleaner, this will only shorten its service life! It should be rinsed only in one case - if you twisted the foam bottle, but you won’t wind up a new one, i.e. put away the pistol. In other cases, use cleaners only separately from the mounting gun.

If you don’t have such a tool, then regular acetone will do, it also easily copes with fresh foam. But here you need to act carefully, because. acetone and products based on it can leave marks on glossy and varnished surfaces. To be honest, fresh foam can be dealt with easily, which cannot be said with dried foam.

If the foam gets on your skin, do not try to wipe it on your work clothes or with a rag, as you will simply smear it, and you will have such a sticky spot on your skin that, by the way, will last for several days. To instantly remove foam from your hands or face without leaving a trace, use a regular transparent plastic bag, you know, like for breakfast. They removed the foam, wiped it with the same bag and that's it, cleanliness. After work, in addition, simply wash this place with soap and dry it dry. No trace will be left.

Foam and cleaner

dried foam

How to clean the mounting foam when it has dried? The bulk of the hardened mass can be removed mechanically without any problems, but in any case a thin yellow layer will remain on the surface, which does not give a damn about your attempts to wipe it off. Under stress, you may come up with a crazy idea, like rubbing it with abrasives or scraping it with a knife. So you will definitely ruin the thing irrevocably. Pull yourself together and go to the nearest pharmacy. There, buy Afobazole, ascorbic acid and Dimexide concentrate. Afobazol will help you relieve stress, ascorbic acid is useful, and you will process foam with Dimexide. There is one bubble within 60 rubles. It is such a local antiseptic and analgesic.

Bottle of Dimexide

The point is… Soak a cloth (not a sponge - it will eat it away) in the medicine and apply it on the foam. The surface must be wet, do not spare Dimexide. Wet the foam properly, leave it for 10-15 minutes, during which time a certain mystical reaction with Dimexide will occur, and you can easily remove it with the entire black side of an ordinary dish sponge without much effort. This method has been around for a long time. Fuck knows how humanity came to this, and who first came up with the bright idea to use a penny pharmacy drug against polyurethane. But the method is 100% working. You can easily see this by watching these videos:

Again, be careful, sometimes Dimexide can affect the surface itself. The paint may change color or peel off, this cannot be predicted. But this doesn't happen often.

If there are also special cleaners for hardened foam, which, in theory, should be sold in stores, but none of our guys personally saw such. True, there is also Cosmofen 5 solvent. This is generally a monster among solvents, but it can not always be used in practice - it even dissolves window plastic. A real beast. There is also Cosmofen 10, it is softer, but it doesn’t “take” foam so effectively either.

There is a more gentle way. Sunflower oil. It works, of course, not so effectively, but it takes place when any risk should be excluded.

How to change the cylinder without clogging the gun

Pistol with balloon

Often inexperienced guys, when they change foam cylinders on a gun, dirty everything around: the gun itself, the cylinder, hands, clothes ... After all, the cylinders are under pressure. But there is simplest way how to avoid this, make everything clean, and pass for a neat master. So you've run out of balloons. You bleed the residue somewhere in the trash so that the residual pressure in the cylinder is minimal. Then turn the gun upside down and unscrew the empty cylinder while continuing to pull the trigger. Thus, you and your gun will not be doused with foam, all the gas will go through the nozzle. Now also wind the balloon, holding the gun upside down from above. At some point, you will hear “pfft”, that's it, at that moment the valve worked, and the foam went into the gun. Everything is clean around.
