In order to avoid such unpleasant situations in the future, it is recommended to follow some tips:

• any construction work involving the use of polyurethane foam is best carried out wearing protective gloves, as well as clothing that will cover all visible areas of the body;

• It’s better to wear the clothes themselves that you don’t mind - at any moment the foam can splash out, or you can inadvertently lean against its fresh layer, so foaming the cracks in everyday trousers is strongly not recommended
• It is better to purchase special products that will immediately help remove sealant that gets on the skin in advance.

This is due to the high adhesion of the sealant - the ability to adhere to various materials. Don't rush to take drastic measures. There are products that will help you wash your hands or hair with minimal loss.

What you need to know about polyurethane foam

• Essentially, it is foam rubber in the form of an aerosol, with the addition of surfactants for adhesion to surfaces, and other substances that give the polyurethane foam (hereinafter MP) the desired properties.
• MP does not stick to Teflon, polypropylene, silicone, oil, polyethylene. This is important to know in order to properly protect the skin of your hands, face and other places while working.
• The rate of polymerization or hardening of MP depends on air humidity. This means that in the presence of water the foam will harden faster.. Do not try to wash off the foam with water, you will only speed up its hardening.
• The foam finally hardens in 4-6 hours, depending on humidity and temperature. The time when a film forms on the surface and the MP can be touched without the risk of getting dirty is 10-20 minutes. Therefore, the faster you take action to remove contaminants, the greater the chance of success.

Of course, it is better not to get into a situation where you need to remove evidence of your own carelessness from your skin and hair, but if this happens, it is useful to know how to do this.

2. Treat remaining stains with a cloth moistened with foam cleaner. This product is sold in aerosol containers and produced by foam manufacturers and is used to clean the mounting gun after use. It removes liquid foam well, but is useless against hardened foam. Acetone is also suitable; it is part of the cleaner and works the same way. You can also use acetone-based nail polish remover;

If the foam has dried, it becomes much more difficult to remove.

Withered

• If the foam has already dried, you cannot do without mechanical cleaning, even after pre-treating it with some kind of compound. Take a pumice stone, a heel grater or a fine sandpaper and carefully wipe off the dirt, being careful not to damage the skin;
• In some cases, vegetable oil can also help. Apply warm oil liberally to the stain and wait 20-30 minutes. During this time, the MP will soften and it will be easy to scrape it off simply with your nails;

Comb out the remains with a fine brush and wash your hair;
• For your nails, make a bath with warm oil. If this does not help, you will have to remove the residue with a manicure file.

The result of the experiment can be seen here

If your efforts are unsuccessful, the remaining foam will fall off on its own within a few days.. The fact is that the skin is constantly renewed and dead cells from its surface are exfoliated. This will happen along with the remaining contaminants in 3-7 days.

To speed up this process, take a hot bath. Foam will be removed more easily from steamed skin.

Polyurethane foam breaks down in the sun. In sunny weather the process will accelerate even more.

It’s better not to allow a situation where you need these tips. Protect your hands with gloves, your body with thick clothing, and hide your hair under a hat. And, just in case, keep a special solvent on hand.

When working with a mounting gun, despite all the precautions, foam tends to get on your hands every now and then. Even using gloves does not always prevent stains. How to wash foam from hands, and is it possible to avoid skin damage? After all, this substance clings to it with the same success as to the porous surface of the wall.

Cleaning your hands of fresh foam

As long as the composition has not polymerized, it can be easily removed using various solvents. The most popular is acetone, which is found in different containers. In your home it may be:

• in cylinders with a cleaning agent for the mounting gun;
• in glass vials for household use;
• in nail polish removers.

It dries out the skin, but does not cause serious irritation if the foam is worked quickly. Compositions such as White Spirit and other solvents can cause itching and burning on the skin, and are worse at removing polyurethane foam. But in the absence of acetone they will also work.

Products such as gasoline and vegetable oil are also used to clean the skin. With them, you will have to scrub your hands for a long time and with effort, but they do not allow the polymer to get stronger and form a crust. This is precisely what is important to avoid when foam gets on your skin.

After treating with any composition, hands should be washed with running water and soap. This is important to do in order to cleanse the skin of dissolved polymer. Failure to wash your hands promptly will result in your efforts being wasted and thin film will still remain on the skin for several days.

What not to do

Do not attempt to wash off the foam with water, even using laundry soap, powder and strong degreasers, of which there are many in any home. Water provokes rapid hardening of the substance, and household chemicals have no effect on it at all. The result of such attempts will be to spread a thin layer of foam over a large area of ​​​​the skin, and such a crust will then be more difficult to remove.

You won’t be able to remove fresh foam with a dry cloth or sponge; the result will be the same. However, you should not resort to aggressive means:

• alkalis;
• acid;
• solvent for acrylic paint.

These substances cause chemical burns, but have no effect on polyurethane foam. But skin damage can be very serious. Trying to cut off an already hardened layer with a knife or blade is also dangerous.

Used to clean various surfaces pharmaceutical product"Dimexide", which is a strong antiseptic. Often, inexperienced professionals make the false conclusion that the medical product is safer for the skin than any solvents. But it can provoke a severe allergic reaction when used in this way, and it is better not to use it.

What if the foam has already hardened on the skin?

If you have not found a suitable solvent, let the foam swell and harden properly. Such a lump comes off quite easily from the skin with careful, slow and smooth movements. Residual marks can be removed with a nail file or pumice stone, or allowed to disappear on their own within 2-3 days.

If, through carelessness, the substance was smeared and hardened into a thin crust, it will be difficult to wipe it off. You can use pumice, sandpaper, or a stiff brush. You need to act gently, without damaging the skin and systematically rolling off the remaining film with the tool. For a better effect, you can first hold your hand in warm vegetable oil.

After work, be sure to lubricate your hands with a rich cream, because after removing the remaining foam, there will definitely be microdamages on the skin. However, redness and irritation will subside within 24 hours.

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

Most of both external and internal construction work is directly related to its use. These are works related to the installation of doors or windows, insulating houses, covering them with siding, and work involving pipe routing.

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

Ways to clean dried foam

In fairness, it should be noted that a small drop of polyurethane foam can cause a lot of unpleasant minutes for a professional. The same one who has never worked with it building material, you may not realize how difficult it will be to get rid of even a small speck of polyurethane foam, because this material adheres 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. There is little hope to be placed on some of the solvents or cleaners we are used to. For example, white spirit will not cope with polyurethane foam.

So is everything really so hopeless?
