How to clean hardened polyurethane foam. How to clean mounting foam? Foam wash

Question: "How to wash mounting foam at home?"- exactly at least once the builders or their wives asked themselves. But the fact is that building foam has a very sticky consistency that eats into any material, which is why a thing damaged by mounting foam can be thrown away. However, there are still ways by which you can wash mounting foam from your hands and clothes, as well as from doors, windows and floors at home. In our article, we will look at these methods to help you clean mounting foam from any surface as efficiently as possible.

From hands

It is the hardest thing to wash mounting foam from hands at home, since it is impossible to apply most of the products that could help when washing mounting foam on your hands. Many chemicals can adversely affect the skin of the hands, so there are only two ways to wash the mounting foam:

using oil or fat cream;
mechanically.

It is necessary to generously lubricate the area of \u200b\u200bthe hands that is contaminated with mounting foam with cream or oil, and only after twenty minutes it can be carefully removed from the skin. The place where the mounting foam was then will also need to be treated with a greasy cream to soothe irritated skin.

Mechanically, you can only tear off the foam along with skin particles. This is a very painful and long process, but if the cream or oil did not help you wash the mounting foam from your hands at home, then the mechanical method will definitely help.

From clothes

Washing mounting foam from clothes at home, without completely spoiling it, is also far from an easy task. Clothes tend to shed and lose color, so many products cannot be used in this case. Let's find out how you can wash mounting foam from clothes, while maintaining its appearance?

So, to wash the mounting foam, which has not yet had time to dry, will help such means:

refined gasoline
acetone
White Spirit.

Find any of these products in your home and before you start washing the mounting foam, try moistening any wrong side of the fabric with it. If the fabric has not lost its original properties, then you can safely use the selected foam cleaner. And you can do it like this:

To begin with, you should clean the clothes from most of the pollution, using a sharp knife or scissors for this. They should carefully cut off the mounting foam, while trying not to hurt the fabric itself.
After that, you need to find a clean rag, moisten it with the chosen agent and use it to wash the remnants of the mounting foam from the clothes. To make this much easier, simply soak a cloth well with the product, and then apply it to the dirt for a while.
When you manage to wash off the traces of mounting foam, you should wash your clothes in the traditional way, adding a large amount of washing powder.

But what to do if the stain of polyurethane foam on clothes has already dried up or become outdated? Do not rush to despair and throw away contaminated clothes. "Dimexide" will help to wash the old stains of polyurethane foam on clothes at home. You can find it in any pharmacy. To wash the mounting foam with it, you must first remove a larger layer of contamination with a knife, and moisten the remaining stain with plenty of dimexide, leaving it in this position for at least half an hour. After that, the clothes should be washed thoroughly.

From the door

Washing the mounting foam from the doors is also quite difficult, especially if it is dried. Foam marks do not decorate the door at all, so let's find out how to clean them.

If the door, on which the mounting foam has fallen, wooden, then it will be easy to wash it at home. To do this, simply cut off the mounting foam from the door with a sharp knife, after which it will be necessary to wipe the remaining foam with sandpaper. If the door after that began to look different, then you will need to varnish the place where the mounting foam was. In the worst case, a slightly yellowish or pale spot will remain on the door, otherwise it is not difficult to wash the mounting foam from a wooden door.

But if the mounting foam got on metal door, then it will be a little more complicated here. To wash off traces of mounting foam from a metal door, the foam must first be cut off, as is the case with a wooden door. Then you should take a clean sponge, moisten it with sunflower oil and apply it liberally to the cut site so that the remnants of the mounting foam soften a little. After that, with the same sponge, begin to gently rub the mounting foam so as not to damage the metal door. When you manage to wash the mounting foam, treat the cleaned surface with a warm soapy solution, which will help remove the oil film on the metal surface of the door.

With plastic windows and panels

Many admit that it is also quite difficult to clean mounting foam from plastic windows and panels, for the installation of which it is very often used. But the fact is that the builders were not too accurate. Now mounting foam spoils the appearance of your room, but you don’t know how to wash it? Well, we are ready to help by providing you with several ways to learn how to clean polyurethane foam from plastic and any other windows, as well as from window sills and plastic panels.

First of all, as in the case of any other surface, most of the mounting foam must be cut with a knife or blade, being careful not to damage the surface of the window or plastic panel. After that, you can choose any product from the list below to wash off the remnants of the mounting foam with it.

If the mounting foam is fresh, then the following means will help get rid of it:

acetone;
vinegar;
sunflower oil;
liquid for flushing the mounting gun.

If the mounting foam has dried up, then you need to use one of the following tools:

means for removing mounting foam from hard surfaces;
dimexide.

Select a foam cleaner that is suitable for your situation and treat the stain with it after cutting off most of the dirt. Leave the liquid on the stain for a few minutes, then take a hard sponge and carefully rub the stain with it. When you manage to wash the mounting foam from the window or plastic panel, wipe the contaminated area with a soapy sponge, then with a clean, damp cloth, and then wipe it dry.

With linoleum and laminate

Washing mounting foam from various floor coverings like linoleum and laminate at home is also quite difficult. For this purpose you you will need a special cleaner for surfaces from mounting foam which can be found at a hardware store. The principle of its operation is simple: cut the mounting foam to the very “root”, then moisten the rag with the cleaner and leave it on the dirt for a while. After that, arm yourself with a hard sponge and wipe off the remnants of mounting foam from linoleum or laminate.

By the way, with the same tool you can easily wash the gun from mounting foam, since this cleaner is just designed for such purposes.

When washing mounting foam from any surface, you should be careful, especially when you cut it off. Check the effect of the selected products on an inconspicuous area of the surface so as not to spoil the thing.

It is very easy to wash mounting foam from hands, clothes, windows, doors or from the floor at home, the main thing is to know what means to use.

Polyurethane foam is a chemical substance in the form of an aerosol, designed for sealing cracks, sound and heat insulation. The sealant is in a cylinder under pressure, when released, the substance increases in volume several times. To wash the mounting foam, use home remedies to start. If this method does not help, use chemicals. Test them on an inconspicuous area first.

Removal methods:

Mechanical (scraping with a sharp object) is used provided that it is frozen.
Acetone (or nail polish remover) is used to remove fresh sealant.
Store-bought products are used depending on the time that has passed since the formation of the stain.

Name	Scope of application
For fresh sealants
ULTIMA Professional	It is used for cleaning windows, clothing, building foam guns.
PENOSIL Foam Cleaner	Removal of mounting polyurethane foam from windows, wooden window sills, metal surfaces, clothes, guns.
Isofoam R621	Universal cleaner.
Cosmofen	Produced by the German company Weiss, it has three modifications (5, 10, 20). Use Cosmofen 20 to remove polyurethane. Suitable for all types of surfaces.
Macroflex Premium	A general purpose solvent cleaner.
Solvent 646	Not suitable for plastic and wooden painted and varnished surfaces.
For cured sealants
PENOSIL Premium Cured	Dissolves and cleans hardened foam from all types of surfaces.
Isofoam R621	Universal cleaner.

Before use, apply the above products to inconspicuous areas of the product. All aerosols are toxic, use personal protective equipment.

Dimexide (or its analogues with identical components) is a drug purchased at a pharmacy without a doctor's prescription.
Sunflower oil - softens pollution, subsequent treatment with soapy water is necessary.
Cold exposure.

From a construction pistol

mechanical method - scrape off the remnants with a sharp object (knife, scissors);
the use of chemical cleaners - place a solvent in a special gun. Press the trigger several times until the solvent comes out.

Windows and doors

Footprints on PVC:

fresh sealant can be removed with acetone, vinegar, vegetable oil, a construction gun cleaner;
lubricate old stains of sealant with dimexide and a foam remover;
dried - remove mechanically.

Be careful when using acetone and thinners on plastic surfaces as they may leave yellow marks.

Ways to eliminate traces of mounting foam from wood and MDF:

You can wipe off the hardened substance with sandpaper. Carefully cut off the protruding parts with a sharp object. This method has a drawback - the possibility of damaging the wooden surface. In case of damage, the door area should be re-varnished.
Salt solution (1 tbsp water to 1 cup salt). 5 minutes after applying the solution, clean the surface with a damp sponge or cloth.

You can clean the metal with sunflower oil. Half an hour after dissolving the chemical, clean the contaminated area with a sponge dipped in soapy water.

Powder-coated iron doors are mechanically cleaned using baking soda and a rubber scraper (soda acts as an abrasive).

Glass

It is easier to wipe the mounting foam from a glass door than from a wooden or metal one. You need to wait for the stain to dry, then scrape it off with a sharp object.

Vinegar will help get rid of stains on tiles. Moisten a sponge or napkin with table vinegar, rub vigorously.

Do not remove the sealant immediately, but do not let it dry completely. It is necessary to catch the moment when the substance will have a "rubberized consistency" resembling plasticine. Take the stain by the edge, pull it slightly - this method avoids streaks and does not require financial costs.

Rules for removal from laminate and floor coverings

Dimexide is used to remove stains from linoleum, laminate, wood, parquet. Do not use acetone for floor coverings, this can lead to streaks.

To eliminate contamination from a carpet or carpet, a damp cloth is placed on the contaminated area, and the foam is completely soaked. After softening, the stain is removed with a sponge dipped in soapy water.

Use store supplies. If they did not help, use less gentle methods: sanding, grinding with a disc.

How to clean foam from clothes

Since the sealant particles reliably bind to the fibers of clothing and fill all the cavities, it is difficult to wipe off the dried mounting foam. Means are intended for these purposes: white spirit, stain removers, distilled gasoline, sealant solvents.

Sequencing:

cut off the protruding parts of the substance;
apply one of the listed products to the contaminated area of \u200b\u200bthe clothing;
wait 15-20 minutes;
remove residues with a sponge or damp cloth;
if necessary, repeat the procedure;
wash the item in the washing machine using multiple rinses.

Preliminary study the information on the product tag, whether the use of chemicals is allowed for this type of fabric.

Foam stains are completely removed if contaminated clothing is placed in the freezer for an hour. Then mechanically clean the remnants of the sealant, if this does not help, use a solvent. Wash the item after cleaning.

Things made of dense fabric (jeans, jackets, overalls) are cleaned with Dimexide. You need to work with gloves, the solution is concentrated and for medical purposes it is diluted with water. Apply the preparation with a cotton swab on the stain for 5-10 minutes and wipe off the dirt with a brush.

Clean clothes made of colored fabrics with acetone - you can damage the thing.
Use solvents with caution on delicate fabrics (cotton, silk).
Do not use solvents on lacquered and painted surfaces, the sealant layer will peel off along with the paint.
Do not use acids and alkalis to remove foam from the face. Polyurethane does not react to them, and a burn will remain on the skin.
Do not wash off fresh contamination with water.

If you plan to do repairs, purchase foam solvents in advance. Before starting work, remove valuables from the room, cover furniture, bath, floors, batteries with oilcloth. Lubricate items that cannot be removed with sunflower oil or fat cream. Carry out repairs in overalls, use gloves and hats.

Mounting foam is so often used during repairs that it is now difficult to imagine the installation of new door blocks without using it. Unfortunately, sometimes it happens that during the blowing of the joints and cracks of the doorway, the foam will get on the door. In this case, immediately take measures for cleaning, since the mounting foam is difficult to remove - it firmly adheres to any surface.

Types of mounting foam

Polyurethane foam is a substance with a high level of adhesion. Foam molecules are able to penetrate the material and tightly bind themselves to it. Remember that when squeezing out of the balloon, the volume of the foam increases.

Before installing the door frame and blowing out the gaps, make sure you protect the surfaces nearby. Agree, it is better to play it safe and cover as many places as possible with a potential hit of mounting foam with a protective film, than then try to remove it without consequences.

However, even such precautions do not guarantee that you will not have to wash the door from drops on the surface. Similar troubles occur with professionals, and with those who first started repairing a house or apartment.

Careful handling of mounting foam when installing the door

Means for removing fresh mounting foam from doors

If during operation you notice foam getting on the surface, try to remove it as soon as possible. Immediately scrape the foam off the door, but don't try to do it with your bare hands - use a plastic scraper or other material that won't damage the door. Try to clean the surface so as not to smear the residue.

Acetone is the most affordable substance to remove the "montage". But its composition is aggressive, so acetone is used only on those surfaces where it is difficult to harm. With a frozen foam, acetone is unlikely to help - such a strong bond is formed between the molecules that the solvent is not able to break it.

Incorrect filling of gaps in the door frame

It is forbidden to use water to wash off traces of foam. When in contact with water, the foam hardens even faster.

Peeled coating after improper cleaning

Prepare in advance - get a substance that can wash the foam

Every hardware store sells proven products to remove the effects of foam on the surface. Let's list them:

Thinner 646, acetone. This option is suitable for surfaces that can withstand contact with an "aggressive" solvent.
Thinner 647. It is not so aggressive, the composition is without acetone, so the risk of damaging the door coating is reduced.
White Spirit.
Kosmofen 5, 10 or 20. The numbers indicate the strength of the substance. "5" is the strongest.
Liquids for cleaning mounting guns from different manufacturers. In this case, pay attention to the composition and choose what exactly will help remove the foam with minimal consequences.

Remember, if you have a chance to immediately clean the surface with minimal damage, go for it! Otherwise, you will wait until it is no longer possible to wash the foam, and mechanical peeling will cause noticeable damage.

Dealing with dried foam

Let's say the substance got on a new door and had time to dry. In this case, it is necessary to proceed with mechanical removal. Do this with a sharp knife or blade. Cut off the dried "montage" as much as you can, and then try to clean it with a metal brush or sponge. But this method, for obvious reasons, is used when the door has not yet been treated with paints and varnishes and scratches on the surface will disappear after applying several layers of varnish or paint.

One way to remove the dried substance on a metal door is with a small, even piece of plastic. It is not able to harm the doors, as it is softer than metal, but it easily cleans the foam.

The real problem is when dried foam has to be removed from varnished plastic or wood. Any aggressive solvent softens the remaining foam, at the same time erasing the top layer.

One of the "folk" ways to deal with such consequences is Dimexide. It is sold in pharmacies. This composition perfectly penetrates into many surfaces and substances. Be careful! When working with the drug, use thick rubber gloves. And before applying to the door, be sure to check the effect on the coating layer in an inconspicuous place on the door.

This is what a vial of dimethylfuxolide concentrate looks like

Further process:

Carefully cut off the foam as far as possible;
Soften the foam stains remaining after mechanical cleaning with the preparation;
Trying not to come into contact with undamaged areas, wash the surface for several minutes;
Using a dull knife, scraper, or the hard side of a sponge, wipe the surface.

Cleaning surfaces:

Remember, accuracy and readiness to quickly clean the foam that has fallen on the door will help get rid of unnecessary problems and long-term elimination of consequences. In order not to frantically search, when working with it, it is better to prepare the necessary funds in advance.

In contact with

When installing a door, window or other construction work, you cannot do without the use of mounting foam. This tool, popular in repair work, 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 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 are various ways to remove fresh stains:

For a metal door, the process of removing foam is somewhat simpler than with a wooden one. If a variety of solvents were used to clean the wooden door, then immediately after rubbing, this area should be washed 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, the clothes should be washed with plenty of detergent.

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 the hands should be washed well under running water, using liquid soap, and rubbed with baby cream.

There are other methods for removing sealant from hands.

The use of table salt. Warm water is poured into a small basin, a teaspoon of salt is added, hands are lowered and they are kept a little in 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 with a small amount of washing powder, lather it and wash off the entire solution from 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.

Almost no type of construction work can do without polyurethane foam. With its help, cracks are closed, window and door openings are filled, certain types of products are glued together, and a lot of other useful actions are performed. In the process of work, it is very rarely possible to do without getting the sticky contents of the cylinder on various types of surfaces in the immediate vicinity, as well as on clothing. The main question of this article is how to clean mounting foam that is in a liquid or already hardened state.

Polyurethane foam refers to substances whose removal causes certain difficulties. Until recently, acetone was considered the only cleaning agent. Now many alternative cleaning methods are used, which we will analyze in this material. Foam acts differently on different materials, so you need to use different products selectively.

We list the means by which you can deal with traces of mounting foam:

Tip: If you decide to use some kind of foam cleanser, treat a small area with it first. If there are no consequences for the surface, you can use this product for a complete cleaning.

Cleaning foam from various surfaces

Freeing the gun from the remaining foam

After finishing work, if a gun was used, particles of polyurethane foam remained in it. How to clean the gun from mounting foam? This can be done in two ways:

mechanical cleaning. With the help of a knife, a flat screwdriver or an awl, the remnants of the frozen composition are removed;
Chemical cleaning. To do this, a cylinder with a foam solvent is inserted into the gun. For example, PENOSIL or OPPA. After that, you should pull the trigger until a clear liquid comes out of the gun.

After such cleaning, the device will restore its performance.

Note: For liquid and already hardened foam, there are different types of solvents. Each of them copes better with a certain composition of the substance.

Cleaning PVC windows or doors

How to wipe mounting foam from a plastic window or the same door? PVC reacts negatively to strong solvents, especially those containing acetone. As a result of interaction with the PVC surface, stains may appear on the surface of the material, which will be impossible to remove.

Foam is removed from PVC windows in an elementary way. When frozen, it is easily scraped off with a plastic scraper or a piece of wood. There are usually no traces left. You can also use vegetable oil, which is applied to the marks and aged for 30 minutes. After that, the dirt is easily washed off with a damp sponge or the same scraper.

Cleaning wooden doors and windows

As a rule, wooden doors and windows are varnished or painted for better protection and aesthetics. How to clean mounting foam from painted or varnished doors? The use of traditional cleaners is not always recommended in order not to damage the smooth surface.

Dissolve a tablespoon of table salt in a glass of plain water, and then treat the contaminated area with the solution. After 5 minutes, wipe the surface with a damp kitchen sponge.

Cleaning of metal surfaces

Don't know how to wipe mounting foam from a metal door? The bulk is cut off, and then the contaminated metal is wetted with sunflower oil. It is aged for 30 minutes, after which the remnants of contaminants are removed with any cloth or sponge. The place of exposure to the oil is washed with soapy water to remove traces of fat.

Removing dirt from glasses

The composition is removed from the glass only when it completely hardens. Using a sharp knife or blade, the composition is scraped off the glass without consequences. There are no marks left on the glass. If there are any opaque areas left, you can use the usual nail polish remover or other solvent.

Floor cleaning

Linoleum

Foam is not absorbed into the surface, so it can be removed very easily. To do this, you need to wait until the composition hardens, and then cut off the bulk of it. Some traces are bound to remain. They can be removed with a special cleaner that does not contain acetone, or with Dimexide. Please note that after using acetone, dull spots may remain on the surface of linoleum.

Carpets

What can be used to clean mounting foam from soft floor coverings in order to do without cutting off the pile? The best option would be to use plain water. The foam binds well to the pile, so it is pointless to remove it immediately with a solvent. Place a cloth dampened with water on the remaining foam. After a few hours, the composition will soften, and it can be easily removed with a brush or spatula.

Laminate

Contaminated areas must be treated with a special cleaner or Dimexide. After the destruction of the foam composition, it will be easy to remove it with a piece of cloth or.

Parquet and parquet board

If the foam is fresh, it is recommended to use one of the cleansers, if available. And how to wash the dried mounting foam? First you need to cut off the main frozen mass. After that, use a solution of dimexide, gently applying it to the contaminated surface with a brush or rag. After 15 minutes, the foam will break down and can be easily removed with a hard sponge used for washing dishes.

Wood

Apply special cleaning compounds or Demixid. These substances are able to penetrate deep into the pores of wood, destroying the particles of foam located there. After an hour, using a brush, the surface is cleaned of foreign elements. In the same way, you can solve the question of how to remove mounting foam from a door or window, which are wooden products.

Important: Be very careful when using strong compounds on varnished surfaces, as they can cause the removal of the varnish layer and the appearance of stains.

If traces of contamination are still visible after the use of solvents, the radical solution remains, such as sanding the surface with sandpaper or a grinding disc.

Cleaning clothes

The question of how to clean mounting foam from clothes is relevant for many people, because clothes are most often contaminated.

It is almost impossible to completely remove the foam from the fabric, since it binds very strongly to the fibers. However, it is quite possible to try to significantly reduce its effect on the fabric. It should be said right away that it is better not to use substances containing acetone, since acetone can change the color of clothes, and even ruin them.

How to wipe the mounting foam that got on the clothes? The following options are suitable for this:

White Spirit;
stain remover;
solvent gasoline. It is pure gasoline without impurities. This is the one to use;
foam solvent.

Now consider, not how to wash mounting foam from clothes, but how:

A cap of foam (fresh or already frozen) is removed from the surface of the fabric.
One of the above compositions is applied to the soiled area.
There is a pause of 15 minutes.
The remains of the substance are removed with a cloth, sponge or soft brush.
If traces of foam remain on the fabric, the procedure can be repeated.
The clothes are washed using powder and stain remover.

We use the freezer

This method can help if there are separate splashes of the foam composition on the clothes, as well as if the foam gets on delicate fabrics.

Do not know how to remove mounting foam from clothes without the use of solvents? We tell:

The contaminated item should be put in a plastic bag, and the bag should be placed in the freezer.
After 1 hour, the clothes should be removed from the freezer, and pieces of frozen foam should be removed from the fabric with your hands.
If stains remain, they can be treated with a stain remover.
Clothes need to be washed.

It is easier to prevent the occurrence of troubles with foam than to eliminate the consequences of such errors later. However, using one of the above methods, it is possible to completely or partially eliminate pollution.
