Any builder knows what to clean polyurethane foam not so easy. It quickly eats into the material, sticks to your hands and often causes damage to clothes. It is impossible to wash off fresh foam with water - upon contact with it, it expands and hardens. It is removed with special cleaners, mechanical methods or using folk remedies. All options have their own nuances, which we will discuss below.

Cleaning hard surfaces

No matter how carefully the work is carried out, occasional splashes and excess foam always end up on nearby surfaces. It is better to remove stains immediately: fresh polyurethane foam is more pliable and does not require the use of caustic solvents.

Procedure:

1. Remove upper layer foam with a wooden spatula or rag. It can also be easily assembled with a plastic bag or cling film– she sticks to them best. If the foam is already dry, use a sharp knife.
2. Treat the remaining adhesive mass with a special cleaner, dimexide ( pharmaceutical product), white spirit, acetone or nail polish remover.
3. Rub the stained area with a hard surface sponge.

In this way, you can easily clean plastic windows, enamel surfaces, and tiles, metal door. If there are no solvents in the house, it remains mechanical method. You can try to scrub the stain with a plastic scraper or a hard sponge using cleaning products.

Cleaning delicate materials

Particular care should be taken when removing polyurethane foam from floors, varnished and laminated objects. Linoleum, laminate and other delicate surfaces may lose color or become deformed from the use of strong solvents. Here it is better to use other methods:

• Mechanical cleaning. Wait until the foam dries a little and stops sticking to your hands (2-4 hours). Grasp its edge and smoothly pull it towards you.
• Using oil. Cut off the foamy top at the root and generously pour sunflower oil over the sticky remains. Now they can be easily wiped off with a stiff brush or sponge.
• Removing dried foam from laminate and linoleum. If 8 hours have passed since the foam sealant hit the floor, all that remains is to cut it off. Remaining dirt should be covered with wet rags. After 20–30 minutes they will get a little wet and will be easier to wipe off.

Many special fresh foam cleaners are suitable for processing plastic, laminate, linoleum, MDF. They impregnate a napkin or cloth and spot remove dirt.

How to remove foam from hands?

Putting your hands with fresh foam under the tap is completely pointless and reckless. From water it expands, becomes larger and harder. But then how to properly clean your hands from mounting sealant?

1. Dry your hands with rags or tissues.
2. To wash away any remaining foam, prepare a saline solution of 3 tbsp. spoons of table salt and 1 liter of warm water.
3. Place your hands in the container with the solution for 5 minutes.
4. Try scrubbing away traces of foam with a piece of pumice.
5. Lubricate your hands with moisturizer.

Some builders prefer to remove foam from their hands with sunflower oil. You can also try removing it with a rag soaked in a vinegar solution (diluted in half with water).

Polyurethane foam is non-toxic and does not pose a health risk. Its presence on the skin is a purely aesthetic problem. If it was not possible to completely wipe off the remaining foam, there is no need to worry. After a few days, the skin of your hands will cleanse itself due to the natural renewal of epithelial cells and the release of sebum.

Removing polyurethane foam from clothing

Cleaning clothes is much more difficult than cleaning hands or hard surfaces. Polyurethane foam can penetrate deeply into fabrics. The thinner the material, the less likely it is that the item cannot be restored. However, it's worth a try anyway.

First, you should let the foam dry, otherwise the stain will spread even more. Then they carefully cut it with a sharp knife “at the root” and begin cleaning.

• Method number 1.

The surest way to remove foam from clothing is to dissolve it. But the product itself is likely to be damaged. Do a test somewhere on the underside: drop a drop of white spirit, acetone, cleaner, gasoline or dimexide. If the fabric has not lost its properties, use a tested detergent for washing clothes.

• Method number 2.

If the goal is not to clean clothes urgently, you can try to destroy the polyurethane foam ultraviolet rays. Just hang it in the sun and leave it for a week or more. When exposed to direct sunlight, the dirt will harden, turn yellow and begin to crumble. You will need to rub the fabric vigorously and shake out the crumbs.

If an attempt to remove foam from clothes is unsuccessful, creativity will help save it. The affected areas need to be cut out and patches installed. After this, you can sew pockets on top, glue emblems, and embroider a design with satin stitch.

Special cleaners

First of all, when working with construction foam, the tool suffers ( mounting gun), as well as adjacent surfaces: window and door openings.

Special cleaners are available to remove both fresh and hardened residues:

• PENOSIL Foam Cleaner;
• REMONTIX PRO ;
• ULTIMA Professional;
• 100% repair;
• OPPA;
• WS profi;
• PENOSIL Cured PU-Foam Remover for dried foam.

The peculiarity of this type of product is the content of caustic substances that can dissolve the foam. But at the same time, they can damage delicate surfaces and are especially dangerous for the skin of the hands and mucous membranes.

Cleaners are used with extreme caution and only with protective gloves.

Some of these products can clean clothes. Before using a particular cleaner, you should read the instructions on the package and conduct a test by spraying the chemical in an inconspicuous place.

People say that dirty hands reveal a bad master. Of course, during repairs, dust and fine dirt will always be present. But splashes of polyurethane foam and severe contamination can be avoided. Firstly, when working with it you need to wear gloves and clothes that you don’t mind getting dirty. Secondly, adjacent surfaces should be covered in advance with old newspapers or oilcloth. And thirdly, the gap must be filled with foam glue in stages and no more than a third. Follow these three rules, and then you won’t have to rack your brains wondering how to remove the polyurethane foam.

A smooth, non-porous surface can be cleaned using a mechanical cleaning method using sharp knives or a plastic card. If the surface has managed to absorb some of the foam, you need to resort to chemical solvents: white spirit or Galosh. For surfaces that do not tolerate solvents well, dimexide can be used. Residual traces are washed with a concentrated warm soapy solution.

Few people use closed protective clothing when working with polyurethane foam, so it often gets on their hands. Nearby objects, furniture, windows, doors made of various materials may also be damaged.

Cleaning PVC windows or doors

Polyvinyl chloride reacts very poorly to treatment with chemical solvents; along with contaminants, the liquid can dissolve the material itself.

Removing foam from PVC surfaces

PVC has a very dense, non-hollow, glossy structure that does not allow stains to be absorbed deep into the material.

Therefore, stuck polyurethane foam, as well as foam, can be easily removed using mechanical methods. Usually a sharp utility knife is suitable for this. a plastic card or any other sharp object.

Note! The sharpened edge used to remove foam must not be damaged or jagged. When they come into contact with the glossy PVC surface, deep grooves and scratches may be left.

By applying moderate force, you can remove stains from the surface almost completely. After using mechanical methods, the window can be wiped with regular detergent and a clean cloth. You can wipe off dried polyurethane foam using needles and nail scissors if it comes to very small stains.

Cleaning wooden doors and windows

To wash off hardened polyurethane foam from wood products and panels, you can use solvents.

They also negatively affect wood, LDPS, MDF, veneer, eco-veneer and all veneered materials, but the reaction does not occur as quickly as it can happen in the case of PVC. Immediately after removal, the cleaned area should be thoroughly washed with soapy water and dried well. Soap neutralizes the effect of the solvent, preventing it from damaging the integrity of both natural wood, and the paintwork, and drying will prevent the window or door from deforming from moisture.

Linoleum

Just like in the case of PVC, linoleum has a sufficiently dense structure so as not to absorb aggressive foam. It is not advisable to remove it with solvents, because they may leave unsightly matte stains. A similar problem occurs with tiles.

Cleaning linoleum

To clean linoleum, you need to use a sharp utility knife, the tip of which can pry the stain right to its very base. Residues can be washed with a concentrated soap solution prepared in warm water, which will also wash away. If the linoleum is dense, then you can use the hard side of a dishwashing sponge or.

Advice : You need to take a new sponge so that its fibers do not contain abrasive materials that can damage the linoleum.

A product called Dimexide (dimethyl sulfoxide) actively dissolves foam, while it is completely neutral to surfaces suffering from chemical solvents.

At the end of cleaning, wipe the surface with a clean, dry cloth to remove excess moisture.

Carpets

The fibers of any home carpet are instantly saturated with polyurethane foam, so a mechanical cleaning method can only do harm.

Dried foam can be removed with plain water.

Using an aggressive solvent is also a bad idea because it can ruin the surface of the carpet (or sofa) and its pattern.

At the same time, old dried foam is unstable to ordinary water. Place a wet rag on the stain and leave it in that position for several hours. The pile absorbs moisture, becomes very slippery, and can even be removed by hand by carefully peeling it away from the carpet.

Laminate

This material also does not absorb liquid foam. It is not worth using mechanical cleaning methods and chemical solvents, because there is a high risk of knocking off the glossy coating of laminite or severely scratching it.

In this case, it is advisable to use dimexide, which does not affect the material in any way, but dissolves foam well. Wipe off the residue construction foam You can use soapy water, after which it is advisable to use an aerosol polish.

Parquet and parquet boards

From a smooth surface, liquid foam can be removed with a regular dry rag or paper towel; if it has cooled slightly, use a wet one using detergents. The dried stain is removed with a solution of dimexide and wiped with a regular rag.

Further care for parquet is the same as for.

Foam on clothes

To clean it from fabrics (silk, jeans), it is better to use solvents such as white spirit, Galosh gasoline or any stain remover that can remove dried stains.

The top layer of the hardened stain is removed from the surface by hand, and the stain is saturated with liquid. After 10-15 minutes it can be wiped off with a cloth. Clothes need to be washed, first for linen.

We use the freezer

If the solvent does not help, then the item should be placed in plastic bag and put it in the freezer for several hours. In frost, the foam will harden very firmly, and it will be easier to remove it mechanically. You can do it in the same way.

Stone, concrete, metal surface

These surfaces are absolutely indifferent to the products that will be used for cleaning. You can safely use both mechanical methods and any solvents.

Untreated surfaces such as iron ( cast iron batteries) and wood, you can even sandblast and treat it with soda as an abrasive. The only exception is surfaces that have paintwork, after treatment with solvent, they will need to be renewed in areas that have become discolored.

Glass surface

Car and window glass can be easily cleaned with a sharp, serrated knife. If you are afraid of damaging the smooth surface, you can immediately use solvents, including acetone. To remove stains that may remain after treatment, you can use alcohol or.

Let's wash our hands

We can only rely on solvents. Using a cotton pad or clean cloth, the liquid should be applied to the foam, trying to avoid exposed skin. Foam as a result chemical reaction will begin to dissolve and you can simply wash it off the skin. Solvents from the skin of the hands also, and.

Advice ! To prevent foam from getting on the skin of your hands, you need to use closed protective clothing and gloves.

After treating your hands with a solvent, you should wash them thoroughly using toilet soap.

Remove from delicate surfaces

If you are in doubt about whether to use an aggressive chemical solvent on a particular surface or material, then it would be best to resort to a dimexide solution. It is guaranteed to leave intact any material it comes in contact with, while the foam dissolves quite actively under its influence.

Aerosols and pastes

As professional assistants To clean various surfaces from polyurethane foam, you can use special aerosols and pastes that have a composition that actively interacts with the foam. For each type of surface you can find a product with an individual composition.

Below is a video that describes how you can wipe off dried polyurethane foam from any surface.

Larisa, June 20, 2018.

Answering the question - how to clean dried polyurethane foam, it is necessary to find out its chemical composition, determine which solutions can remove such contaminants without leaving a trace. There are many special liquids that will help effectively remove hardened foam from wooden, metal, and plastic surfaces. But what to do when the product gets on your hands, body or face? This building material consists of polyurethane foam, has a high degree of adhesion and strong adhesive properties. That's why it's so difficult to clean off various surfaces. But this needs to be done! How can you wash polyurethane foam from wooden products?

When the foam gets in the wrong place...

In such cases, acetone comes in handy; it dissolves liquid foam right before your eyes. But he will serve as an assistant until the composition dries out. And then only mechanical or chemical means will be required.

1. Used metal brush, scraper or knife. Hard pieces of building material are first carefully cut off and then rubbed down with sandpaper.
2. Special cleaners for hardened foam: “Platina Cleaner”, “Russian Professional”, “Purex”, “PENO-OFF”, “HOBBY”.

Methods of using such products.

The can is shaken and sprayed onto the contaminated areas; after ten minutes, the remaining foam is removed mechanically, and the surface is wiped with a cotton rag.

Attention: you need to monitor the area where the cleaning solution hits, otherwise you can remove paint, varnish, and other protective materials along with the foam. Spraying the can near a fire is strictly prohibited!

You can completely abandon chemicals and try to wash dried foam with folk remedies.

The drug "Dimexide" removes traces of construction foam

Dimethyl sulfoxide can be purchased at any pharmacy at a nominal price without a doctor's permission. You need to work with it carefully, the product is absorbed into the skin and affects a person’s well-being.

The procedure is as follows:

• wear rubber gloves;
• concentrated solution in pure form applied to contaminated areas for 40 minutes;
• the foam is removed, the stains are cleaned with a brush (if the product was used on clothes, then after cleaning you need to wash them thoroughly).

Vegetable oil

Apply for 30 minutes to the remains of dried foam and can be easily removed with a regular rag. Such a product will be just right if building materials come into contact with your face, hands, or body.

Laminate and linoleum can be easily cleaned using all traditional and chemical methods.

Direct sunlight

This is not a joke; in fact, in the sun, polyurethane foam has the ability to change its structure and gradually collapse. This method will perfectly clean your old favorite jeans or carpet surfaces, which can be hung outside and “knead” the contaminated areas from time to time.

To remove foam from clothes, you can try using a special cleaner, then soak the item in the powder for several days, and rinse thoroughly. The stains may not disappear without a trace, but you can certainly discolor and remove dirt from fabric materials.

Attention: Do not wash off the mounting foam with water. So, it penetrates even deeper into the material and dries more firmly.

How to put your “working tools” in order after finishing work

Cleaning a gun from polyurethane foam is not easy, and sometimes impossible. It should not be disconnected from the cylinder while construction work is in progress. Every day you need to rinse the tube with a special solution, white alcohol or acetone.

If the gun can no longer be cleaned, then you need to disassemble it. It is necessary to unscrew the crown of the seat and pour solvent inside. Then assemble the mechanism. You can also poke a hole with a thin wire and shake out the frozen foam from the gun.

This way, the functionality of the device will be properly maintained throughout the installation work.

Removing foam from plastic and glass

How to clean hardened polyurethane foam from plastic windows? To do this, you can use a regular oil solution. Apply sunflower oil generously to the contaminated area, let it sit for 30-40 minutes and then intensively wash it with a rough pad of a dishwashing sponge. When the stain has almost disappeared, you can wash the window with a solution of 75% laundry soap or washing powder.

If the window frame is wooden, then the remaining foam can be wiped off with sandpaper and the surface can be painted over.

Remove dried foam from hair

If strands of hair are contaminated with foam, then it must be removed using a drastic method. Cut off the hair skein. Or try using the folk remedy “Dimexide”. It is important to be careful because the medicine is potent and quickly absorbed. The use of chemicals is strictly prohibited!

But to clean stains from polyurethane foam from furniture upholstery or other dense fabric coverings is possible in a simple way. You just need to scrape off the foam with a thin blade or sharp knife. Wash with powder and special stain remover. When delicate fabrics become dirty, it is better to contact a dry cleaner to avoid leaving a scorched stain on velvet, silk and acetate.

Attention: foam is “afraid of the cold”, the soiled item can be put in a bag and put into freezer. This does not apply to bulky fabrics, various types of clothing. After freezing, the foam is easy to remove with your hands; it becomes pliable and fragile. Then the item is thoroughly washed.

This is how to clean fabric from polyurethane foam!

So simple and safe ways remove stains will help preserve fabric products, wood, glass, metal and plastic materials safe and sound. And when using chemicals You should be careful and strictly follow the rules for using flammable solutions. The following video on how to clean polyurethane foam will tell users about the nuances and options for eliminating traces of this building material on various surfaces.

Video: How to remove polyurethane foam from your hands

Sometimes repairs end in trouble in the form of dried polyurethane foam not where it is needed. It gets onto repaired surfaces, clothing, furniture and even exposed skin, causing a lot of problems.

If it has dried out, then removal is not an easy task. Foam varies according to chemical composition, but the main components are polyurethane foam and adhesives with high adhesion. For this purpose, a number of special cleaning liquids and mechanical methods are used.

Cured polyurethane foam

Getting rid of marks, dried or not, requires a set of tools. Fresh drops are removed using the following:

• Liquid for washing guns. There are many formulations on the market. The product is only suitable for removing uncured compounds.
• Nail polish remover. It is acetone based.
• Edible vinegar.
• Rags.

To remove already dried foam you will need:

• A special product is “foam cleaner”.
• Brush. Needed for applying solvent liquids.
• Soft rags - rags.
• Medicinal drug "Dimexide".
• Spatula, knife, scraper, dish sponge or unnecessary toothbrush.

Removing fresh foam

While the stain has not dried, it can be easily removed with a cloth or spatula (scraper), and the remaining residue can be cleaned using gun washing liquid. Before use, check the liquid for effectiveness and harmlessness to the surface being cleaned.

If the surface does not deteriorate, continue. Wet the rag, wring it out, and then rub off the stain without much effort.

Acetone, nail polish remover and other solvents, such as 646, cope with this task. The removal procedure is the same. They also use heated oil. Wet a napkin or cloth and act carefully, first wet the stain, and then begin to wipe off the foam.

Removal with a napkin

After using solvents and other special liquids, wash the surface with soap and water. This stops further aggressive effects of chemical residues on the surfaces being cleaned.

Foam can be easily removed from tiles without any residue using ordinary table vinegar. It is recommended to do this this way: moisten a rag or napkin with vinegar, place it on the stain and leave for a while (five minutes). Then remove the residue with a rag.

Removing dried foam

This foam is dissolved using special means. It is better to buy them in specialized stores. Be sure to ask about the method of application. Instructions are always present on the packaging.

They are sold in cans. The method of application is simple - shake the can and then spray the liquid onto the stain. After 10 minutes, remove the softened residues with a scraper, then wipe the surface to be cleaned with a napkin. Sometimes these products are available in the form of a paste or gel. It is better to apply them with a brush.

In cases where mechanical removal is possible (the surface is not damaged), cut off the hardened foam with a knife and then scrape it off with an accessible tool.

The drug is well absorbed by the skin pores and can affect your well-being. Therefore, they work with it in protective gloves, as with any other chemical.

Polyurethane foam cleaner

This is how you should use it. The liquid is applied to the stains, left for 40 minutes, after which the dirt is removed. If the product was used to clean clothes, it is better to remove any remaining dirt with a toothbrush. Be sure to wash your clothes after this.

A common way of fighting among the common people is as follows:

• First, use a knife to cut off as thick a layer of foam as possible.
• Then break off pieces from the remaining stain so as not to scratch the coating. Do this with a blade or paper knife.
• When the bulk of the foam has been removed, scrub the surface with the hard side of a dishwashing sponge. This must be done carefully, otherwise the surface will be scratched.

Still using it physical and chemical properties the foam itself. It decomposes when exposed to sunlight. If you leave a contaminated item in the sun, it is much easier to remove the dirt. The method is especially relevant for cleaning clothes.

To clean the gun, squeeze out the remaining foam from it, and then apply the cleaner to the surface. After this, insert the can into the gun and pull the trigger until cleaner comes out of the spout. Leave the gun alone for a couple of minutes and pull the trigger again.

How to remove dried foam from clothes

It is unlikely that it will be possible to completely and painlessly remove such contamination from clothes with deep pile, but you can try. To do this, you need to purchase a special cleaner. After using it, the item should be left soaked with washing powder. After a few days, wash it.

Removing polyurethane foam from the door

Foam doesn't hold up negative temperatures. Dirty thing put in the freezer for several hours. When the foam freezes, it will become brittle and must be removed by lightly rubbing. But this remedy is not always effective. You will have to work hard, for which you will need scrapers, various cleaners, solvents and acetone.

After this, mechanical cleaning is again needed, but this time by hand. Stretch the clothes thoroughly, then cover the stains with liquid again and leave again for 30 minutes. After performing this operation several times, they achieve good results. The next wash will complete what was started.

Polyurethane foam contains acetone. Therefore, they remove it with its help. Moisten the clothing fabric well and knead it with your hands. Do this several times until the stain comes off. After this, wash the item.

If you have the opportunity and the means, it is better to leave your clothes to dry cleaning. Specialists will cope with this task faster and better.

WITH furniture upholstery, if the fabric is thick, scrape off the stain with a razor blade, and then wash with washing powder and stain remover.

The video shows the process of removing foam from clothes using dimexide:

How to remove foam from hands

To remove dirt from the skin of your hands, do not use strong solvents. Special means Use only with extreme caution. After some time, the polyurethane foam will peel off on its own under the influence of sebaceous secretions. Some use vegetable oil. It will soften the stain, making it easier to remove.

Removing foam from upholstery

Apply the oil for half an hour and then remove the dirt with a soft cloth.

It is more difficult to remove foam from hair. More precisely, it is impossible. The hair will have to be cut or washed with dimescid, which is not recommended from the point of view of collateral damage to the scalp and the effect of this drug on the human body.

Summarize. Work with polyurethane foam wearing protective gloves and a hat to prevent it from getting on your hair. The space around the foam treatment area is covered with mounting tape, film or paper, for example, newspapers. Only by following these recommendations can you save yourself from the above problems.

In contact with

Polyurethane foam is a long-known and very popular material that is used for all kinds of work. But when using foam, various unforeseen situations often occur when it ends up where it shouldn’t. The peculiarity of this material is that it cannot be easily wiped off. How to remove polyurethane foam from laminate flooring, is it possible to save the floor covering?

When carrying out major renovations in an apartment, sometimes it is impossible to do without some special tools. One of them is ordinary polyurethane foam. It is so multifunctional and easy to use that one can only wonder how they coped with repairs without it before.

Everyone is familiar with polyurethane foam, even those who have never used it in practice. It can protrude from the cracks of houses and is used during installation plastic windows, often visible from under internal lining garages. In appearance, the frozen yellowish material is very reminiscent of foam plastic. It is quite durable, has a large number of pores, and does not sink in water.

From the point of view of chemistry and construction, polyurethane foam is a polyurethane foam sealant packaged in a container, reminiscent of the packaging of a regular air freshener or a can of spray paint. Inside the cylinder there is directly a liquid prepolymer and a gas that displaces it from the container. When the foam comes out of the can, it polymerizes fairly quickly into rigid polyurethane foam.

Polyurethane foam is a polyurethane foam sealant

The material is widely popular due to its properties:

• perfectly insulates treated surfaces;
• easy to use - just purchase a cylinder and a special gun for the job;
• hardens quickly;
• saves work time;
• not afraid of moisture;
• does not conduct electricity;
• has excellent adhesion to any surface;
• penetrates well even into small cracks and gaps;
• can be used in professional construction and for minor installation work.

On a note! Previously, tow and cement were used instead of foam, which in comparison are quite difficult to work with. The cement required preparation and took a long time to dry, which resulted in long installation times.

Polyurethane foam is ideal for sealing all kinds of joints and seams, moreover, between almost any materials. It is also used for assembling the most different designs made of plastic, wood, metal. Foam does not work only with the following types of coatings - Teflon, polyethylene, silicone. In general, the options for using polyurethane foam can be very different; it is enough to know how to use it - the final result will depend on following the technology for working with it.

Aspects of using polyurethane foam:

• work is carried out only at air temperatures from +5 to +30 degrees;
• working with the material requires gloves;
• the optimal width of the cracks for sealing should be in the range from 1 to 8 cm;
• Before work, the gaps are treated with water - the humidity of the treated surface should be 60-80%. This will affect the quality and speed of polymerization;
• Before starting work, shake the container well;
• The time for complete hardening of the foam is about 8 hours.

On a note! Foam does not like exposure to ultraviolet radiation, so it is better to hide it from sunlight with a layer of putty, plaster or casing.

Due to all the properties described above, foam is quite poorly removed from various surfaces. Therefore, you need to be careful when working with it.

Features of laminate cleaning

Laminate is one of the popular materials for flooring. It consists of several layers, the topmost one - protective - is represented by melamine resin. The material does not like moisture, but in general it is not fussy about care and is easy to clean. But if the laminate is not properly cared for, the coating becomes dull, becomes stained, begins to bulge, etc. Therefore, you need to care for the material correctly.

Laminate cannot be:

• treat with aggressive chemicals– they can irreversibly damage the coating and leave stains on it. Such substances include alkalis, acids, chlorine-containing agents and ammonia;

Attention! Before using any laminate floor cleaner, you should first test it on small area surfaces and only then process the entire coating.

• clean using abrasives and mechanical cleaning. These methods can damage protective layer coating and quickly render it unusable;
• wash without first removing sand and small stones(these items can act as natural abrasives and ruin the laminate);
• treat with products intended for parquet, which contain silicone;
• over-wet– water is destructive for this type of coating (with the exception of moisture-resistant laminate).

How to secure laminate flooring

Laminate and polyurethane foam are incompatible, however, these materials may accidentally “meet” during apartment renovation. Foam can easily get on the floor covering, and it can’t be easily removed. That is why the laminate should be made as safe as possible before starting work:

• the laminate can be covered with cardboard or polyethylene;
• You need to work carefully and carefully, trying to avoid getting polyurethane foam on the floor.

However, in any case, no matter how much you cover the coating before starting repairs, it is quite easy to get it dirty. And cleaning laminate flooring after finishing renovation work is not the easiest task.

The first step is to remove large-sized debris; however, you cannot drag pieces of cement or bricks over the surface. You need to carry them, holding them suspended above the laminate, otherwise you can easily scratch the surface. Then, use a broom or brush to carefully sweep away smaller debris and throw it away. Construction dust The easiest way to collect it is with a vacuum cleaner.

Only after completing the previous list of works can you begin to remove stains from all kinds of construction compounds– glue, cement, paint, as well as polyurethane foam.

How to wipe off polyurethane foam

You can wash the laminate from polyurethane foam using specialized means or using improvised means. Special preparations can be purchased at a hardware store. Before purchasing, it is important to carefully study the instructions for use and look at the composition of the drug. For laminate, products containing acetone or ethyl alcohol can be used.

Let's take a closer look at some well-known means. Among them there are special formulations, and those prepared on the basis of improvised means or medications.

Important! For laminate flooring, you should not use the first cleaning agent you come across. The fact is that some of them may contain substances with which this type of coating is not friendly.

Table. Available and safe means to remove fresh foam.

Name	a brief description of
	In this category there is various compositions. Some are designed to remove fresh foam that has not yet dried (Penosil Foam Cleaner, Oppa and others), others are used to remove hardened composition (Penosil Premium Cured, etc.). Foam that has not hardened is first removed with a spatula or a wooden sliver, and its remains are collected with a sponge soaked in cleaner.
	Not the best option, but still capable of sometimes coping with polyurethane foam. The bulk of the foam is cut off with a knife, and a damp cloth is placed on its remains and left in this place for some time. The foam will soften and come off easily. However, it is important to remember that laminate does not like water and you should be careful not to spoil the coating. It's better to add a little salt to the water.
	This is Cosmofen or WS Cleaner pro. These drugs are quite potent, so it’s better to try them on an inconspicuous area of ​​the floor before scrubbing off the foam with them.
	A pharmaceutical drug that is used to treat various diseases, including inflammatory ones. Surprisingly, it is Dimexide that is considered one of best cleaners polyurethane foam. It will cope even with already dried composition. The main part of the foam is removed using a stationery knife, and then Dimexide can easily deal with its remains. It is sold in pharmacies without a prescription, and you only need to work with it with gloves, as it can burn your skin if undiluted.

Dimexide is one of the best options

Unfortunately, after removing the foam, stains may remain on the laminate. And it will most likely not be possible to deal with them without sanding. The slats may need to be replaced.

The best way to remove foam from laminate flooring is with a special cleaner; it penetrates perfectly even into the textured grooves of the coating and softens the foam very carefully.

On a note! Fresh polyurethane foam can sometimes be removed by ordinary salt, or rather, its solution. But the composition cannot be kept on the surface of the laminate for a long time - salt and this type of coating can come into contact for no more than 5 minutes.

Also, sometimes a dishwashing sponge, which has a rather dense surface on the back, helps out. It is with this surface that the stain from the polyurethane foam is treated. But it is important to rub carefully so as not to spoil the coating. The slower the procedure is carried out, the less likely it is to render the laminate unusable.

Important! The fresher the foam stain, the easier it is to remove. Therefore, there is no need to delay cleaning the surface.

Features of cleaning surfaces covered with old stains of polyurethane foam

It happens that a stain of polyurethane foam on the laminate was noticed late. The composition had time to polymerize and solidify securely. However, not all is lost, and it is still possible to remove the foam.

On a note! It is not always possible to wash hardened foam the first time. Sometimes it takes several procedures to say goodbye to the stain forever. Especially on such a delicate surface as laminate.

Vegetable oil will help remove foam from laminate flooring. A piece of material is cut off at the root, and the remaining thin film of foam is treated with oil in this way - a sponge is moistened in it and then applied to the foam. The oil will be absorbed into it and soften the material within 15-20 minutes. Next, the sponge is turned over and placed on the stain with the abrasive side - the foam is simply rubbed off.

However, after this procedure you will have to deal with greasy spots. They can be removed with ordinary soapy water.

The aforementioned Dimexide is an excellent fighter against old foam. In the same way, excess foam is cut off with a knife, and a pharmaceutical preparation is applied to the remains. There it remains for a while, and then the surface is rubbed again with a sponge. You can wash off the remains of Dimexide with water or soap solution.
