How to wash old paint. How to remove old paint: proven ways to quickly remove paint (95 photos). Removing paint from clothes

When making repairs in an apartment or house, sometimes it becomes necessary to remove old paint. The coating, despite its age, keeps firmly and firmly. Exist different ways withdrawals.

How to remove oil paint from walls

They have great durability. Even the swollen paint, which is about to fall off, holds on tight. The choice of stripping method depends on several factors. So, how to remove from the walls oil paint?

When you need to remove oil paint from the walls

The need to remove the old coating arises when you need to level the walls with plaster, putty, paint, wallpaper or tile with ceramic tiles. This is necessary for the new coating to hold firmly. If the work is done on an old paint layer, the result may not last long.

Methods for removing oil paint

Methods for dismantling oil paint:

• Mechanical.
• Chemical.
• Thermal.

The best mechanical way

The mechanical method does not require financial costs, but involves physical labor. Requires an ax to complete.

The method is suitable if, after removing the coating:

• you will level the walls with plaster;
• tiling.

This is due to the fact that the plaster and adhesive mortar have adhesion to a rough surface. Cleaning is chopping off the oil solution from the wall.

Operation instruction:

1. On the surface to be cleaned, notches are made with a sharp axe.
2. After that, the wall must be moistened with water using a spray bottle or a rag.
3. As it dries, the coating is peeled off with an ax. The tool needs to work at an acute angle.
4. After that, the surface is cleaned with sandpaper.

If work takes place in a room without ventilation, then the respiratory organs are protected with a gauze bandage.

The coating is also removed using a grinder or a drill with a special nozzle:

• With a wide abrasive wheel or a round metal brush - for a grinder.
• Brick crown - for a drill.

Thermal option: how to quickly remove a layer of paint

softens under high temperature. If the paint is heated, then it is easily removed with a spatula.

Instruction:

1. For heating, a building hair dryer is used. The desired area is heated.
2. The paint is removed with a spatula.

If you don't have a hair dryer, an iron will do. It is only necessary to heat the surface through the foil.

It is necessary to use this method in ventilated rooms, because when heated, harmful substances. In addition, despite the cleanliness of the method and speed, there are nuances: it cannot be used near electrical wiring and on surfaces that are afraid of heating.

Not to be used as a heater gas-burner, blowtorch or another source of open flame is dangerous.

Chemical Remover: The Best Paint Remover

To remove the oil coating, a special tool has been developed - a wash. The composition includes chemicals and solvents. Under the influence of the wash, the paint softens and is taken in with a staple or spatula.

Chemical washer must be handled with extreme care because it contains harsh chemicals.

Instruction:

1. The wash is applied to the surface with a brush or roller in one direction.
2. After a certain period of time (which is indicated in the instructions for the product), the surface is cleaned with a tool.
3. If necessary, repeat the procedure. This usually needs to be done if the paint is applied in several layers.
4. When the work is finished, the mixture of paint and thinner must be disposed of.

Washing has a big disadvantage: there is a danger of poisoning chemicals. Application of the product is possible only in a well-ventilated area or with a powerful hood.

The solution has a persistent odor, so until it completely disappears, it is not recommended to live in the room where the wash was used.

In addition to the above, the wash has a high price. Therefore, this method will significantly hit the wallet.

Safety regulations

Cleaning the surface paintwork material you must follow the safety rules:

• It is necessary to ventilate the room, especially when using a chemical wash.
• Use personal protective equipment - a gauze bandage to exclude damage to the respiratory organs and mucous membranes. Protect your eyes from dust and paint particles. Use special gloves for hands.
• With the thermal method, carefully select the surface, do not heat flammable surfaces and with electrical wiring.
• When working with a wash, strictly follow the instructions.
• Be careful with tools.
• If the room where the work is being carried out has open wiring, then the room must be de-energized.
• When using a ladder or stepladder, it is better to put rubber tips on the lower ends so that it does not slip.
• Clothing should be comfortable.
• Remove hair so as not to interfere.
• The room should be well lit.
• In the room where heating devices are used, it is forbidden to smoke and use open fire.

When it is impossible to remove oil paint from the walls

has durability. but is removable. If the paint is laid in several layers, then the procedure must be repeated until the coating is completely removed. Particularly time-consuming process of getting rid of oil paint with concrete surfaces. The coating can be removed from any surface, you only need to stock up on strength and patience.

Special Moments

The chemical and thermal methods differ in speed from the mechanical ones. But, despite the laborious process with an ax, this method is one of the safest. By cleaning the surface in this way, no harmful and toxic substances remain.

In the event that you plan to refresh the paint, then removing it from the surface is not always necessary.

Removing the oil coating is a laborious process. Carefully consider the choice of method and follow the safety rules.

mechanical method

One of the first thoughts that arises when looking at a layer of paint that needs to be removed is: “Yes, it will be the easiest to peel it off!”. And now the hands are already reaching for a grinder or a drill with grinding nozzles. We recommend not to rush and analyze the situation, because mechanical removal is not that inefficient, but it is not suitable for all products.

• Can the product be taken outside? There will be an incredible amount of dust and flying pieces of the coating, and if you start removing paint indoors, then you will have to start a major cleaning later. Plus, you will have to work in a respirator and glasses, which is also not very convenient.
• Is there a thick layer of paint on the product? Previous generations did not stand on ceremony with oil paint: tired of the color - just repaint old layer new. It turns out that on some Soviet doors, a layer cake of 4-5 layers of oil paint has accumulated, each of which is much thicker than the layer of acrylic paint that we use now. With the mechanical removal of such a layer, you will score more than one skin without achieving the desired result, and this is not only insulting, but also quite expensive.
• Is the product stationary? Removing varnish from the legs of a chair with a grinder is a good idea, but cleaning a window frame or skirting boards that you are not going to beat off the wall in this way is not very good - because of the risk of touching a wall or window with a grinding disc.
• Is the surface of the product flat? If the product has cavities or protrusions, then the mechanical method will not the best choice removing paint, as it will still remain in the joints and recesses.

It turns out that you can remove the paint by grinding if its layer is not thick and the surface is even, otherwise the efforts spent on removing the coating will not be worth the result that you get.

Sometimes for thin layers it is enough to rub the coating with a metal brush and sand it with sandpaper with a medium abrasive. If the surface area is small, then it is The best way remove paint without special tools and substances.

Chemical method

Quite quickly and easily, chemical washes, which are sold in construction stores. Only they, of course, do not wash off the paint, but rather soften it, so you still have to work with a spatula. Typically, such a product is applied to the product with a brush or roller, left depending on the type of product and instructions - usually for 20-40 minutes, and then the softened layer is pryed off and scraped off with a spatula. If the first time it was possible to get rid of only part of the paint, then the procedure is repeated, but the smallest residues can be cleaned with sandpaper.

It is important, when buying such a wash, to check with the seller or make sure for yourself that it is suitable for your type of material and paint. You can save yourself the hassle of looking for a specific washer for your type of paint by purchasing an all-purpose cleaner. Also, think in advance about whether you can leave the room for the duration of the wash and then ventilate it well or take the product outside. If yes, then you can take a regular solvent-based paint remover, if not, then it is better to give preference to more modern expensive odorless gel washes. That's just the absence of smell does not mean that they are not toxic: with any wash it is necessary to work with gloves, and the room must be ventilated.

According to the experience of builders, we can say that cheap washes Russian production do not do well with old oil paint if it is applied in several layers. With more expensive foreign counterparts, this problem does not arise.

If you have, then you can not spend money on special washes at all: add a little water to it, dissolve soda, and then mix with ground oatmeal to get a paste. Apply the paste to the product, wait about an hour until bubbles form, remove the paint with a spatula, and then degrease the surface. Gloves and ventilation are also relevant for this method.

Do not use plastic container and tools when working with a wash, as they can deteriorate from exposure to chemistry. Also, do not use washes if close to wooden product located plastic.

thermal method

The latter method is considered preferable for removing paint from wood, since it can be done quickly, easily, inexpensively and without harm to the product itself. It consists in heating the paint to a temperature at which it begins to correct and release gas. This will cause it to bubble, and it will be easy for you to peel off the old layer by prying these bubbles with a spatula. But what is the best way to do it?

Heating with an open flame, such as a burner, is not only dangerous, but will also have questionable results. Yes, the paint will start bubbling, but fire can lead to drying out of the wood, burnt spots on the product, or poor-quality subsequent painting due to resins released during the treatment with a burner.

It is better to use a hair dryer, but not a household one, but a construction one. Its heating is hundreds of times stronger, and the paint begins to lag behind the wood literally before our eyes: just have time to pry it with a spatula. Of course, it’s scary for an inexperienced person to work with such a hair dryer: if you accidentally point a stream of hot air at yourself, the case will 100% end in a hospital. But subject to all security measures, this method beats all the others! If you have a person willing to lend you a blow dryer for a day.

Strong heat, like chemical treatment, are not allowed if the product has plastic parts that cannot be dismantled. Also, do not heat the wall with a hair dryer in areas where the wiring passes, as this can lead to damage to it.

Or maybe not remove the old layer at all?

Yes, it is often necessary to remove the old layer of paint, especially when the paint has begun to crack and peel off or when the surface has become very uneven and bumpy due to the multi-layering. But you don't have to go through the long and complicated process of stripping paint by choosing a new coat on top of the old one.

The surface will have to be prepared: the oil paint must be sanded, removing the bumps, then washed with an alkaline solution, such as soap, primed with an alkyd or synthetic primer, and then apply a new layer. If after grinding the surface is still not leveled, the product can be puttied before priming.

If you want to get a translucent effect with a translucent wood texture, then the paint will have to be removed, even if painting a new layer on top of it is quite possible.

You will need some skill in removing paint from wood, but once you figure it out once, you can easily repeat the procedure if necessary. How exactly you will remove the coating is up to you, but, you see, now you have plenty to choose from.

Often a person faces the need to remove paint from metal. Any coloring composition becomes unusable over time, rust can appear through it.

Sometimes paint spots appear on the surface of the product by accident. To cope with the task, you need to act carefully, following the advice of professionals.

From this article you will learn how you can remove the old one from metal at home.

Before you get started, you need to properly prepare. This complex includes:

When all preparatory stages completed, work can begin.

How to clean old paint off a metal surface?

There are three main ways to remove paint from metal:

1. Mechanical. The composition is cleaned by the application of physical force.
2. Thermal. The coating is softened with high temperatures, after which they are removed with improvised means (most often with a spatula).
3. Chemical. Use special washes and solvents.

Sometimes a combination of several methods is required.

How can it be removed mechanically?

The tools that are used to remove paint from metal surfaces are:

• drill;
• Bulgarian;
• Grinder;
• putty knife.

The most important point is the choice of the correct attachment for the power tool. The priority is abrasive coatings.

Drill cord options:

1. Radial. They are used to remove paint in hard-to-reach places ah, for example, inside the pipe.
2. Cylindrical. They are narrow, it is convenient to clean off the paint between the elements of heating radiators in the apartment.
3. Disk. They are suitable for cleaning flat surfaces.
4. Cup. They are used for rough work when a thick layer needs to be removed.

Circle options for grinding machines and Bulgarians:

1. petal circle. It is used when, together with the paint, it is necessary to additionally remove a layer of metal.
2. Cleaning circles from nonwoven fabric CD. They are suitable for gentle removal of the coating. The resulting scratches are easy to cover with a subsequent layer of paint.
3. Cibo cleaning wheels. These tips feature a smaller abrasive grain and thin nylon thread, so they work more delicately. It is these circles that are used if you only need to remove upper layer paint, no damage metal surface.

Using a grinder or grinder, you can remove paint from flat surfaces that are not difficult to access.

For working on corners, curves and fine details without manual labor not enough. To do this, seek help sandpaper and a metal spatula.

Mode of application:

Mechanical cleaning is accompanied by the appearance of a large amount of dust and chips. Therefore, it is imperative to protect your eyes with plastic goggles that will fit snugly to your face.

Heat treatment at home

The principle of this method is the removal of the coating by high temperatures. Under their influence, it begins to melt, making it easy to remove with a spatula or spatula.

Tools that can be used:

1. Building hair dryer. It is he who should be given priority when carrying out work.
2. Blowtorch. It is a source of open flame. Under its influence, the paint burns out. It remains only to clean it with a brush.
3. Iron. They heat the surface of the metal through some material, for example, through foil. In this way, it will be possible to work out only small surfaces. The method is considered the most time-consuming and inefficient.

Paint removal method:

After cleaning is completed, paint may still remain on the metal surface. It is removed with a solvent. It can be applied only after the product has completely cooled down.

Do not thermally remove paint from cast iron, brass and aluminum battery heating. It is forbidden to glow decorative thin-sheet elements, especially those that make up a composition with other materials.

How to quickly clean with chemicals?

What else to wash off the paint? The use of professional washes allows you to quickly get rid of the coloring composition, regardless of its type.

In practice, various solvents are used, among which:

1. Aerosol KUDO. The cost of 520 ml is 230 rubles.
2. Aerosol Veslee Remover. The cost of a composition with a volume of 450 ml is 180 rubles.
3. Wash Syntirol. For 1 kg of funds you will need to pay 470 rubles.

Mode of application:

All washes have a pungent odor, so you need to work with them on outdoors or in rooms with good ventilation.

How to remove from the gate?

To peel paint off metal gate, you need to perform the following algorithm of actions:

• remove all contaminants from the metal surface;
• walk through the gate with a grinder - the nozzle must be selected depending on the number of layers of paint;
• work out hard-to-reach places (joints, welds, loops) with a brush with metal bristles;
• apply a solvent to the surface of the gate - this will get rid of the remnants of the coloring matter and degrease the metal.

After such cleaning, the gate will be completely ready for further processing.

If it was decided to remove the coating with a wash, then a thick composition is chosen: gel or aerosol. The gates are located vertically, so liquid products will drain from them and will not have the desired effect.

You need to clean the paint on a sunny day. Rain can cause work to stop.

Peculiarities of removing different types of paint and varnish products

Any paint can be removed mechanically, thermally or chemically, but sometimes some methods are more preferable.

The most common mistakes

When removing paint from a metal surface the following mistakes should be avoided:

In order to avoid mistakes when performing work, you need to know what kind of metal the product is made of and what type of paint it is coated with.

Removing paint from metal you need to use the following guidelines:

1. Observe safety precautions. Hands, respiratory organs and eyes need protection.
2. Take care of cleanliness. Less dust will form if the surface is sprinkled with water before mechanical cleaning.
3. Do not overheat the paint so that it does not catch fire. It is possible to start applying a metal remover or solvent only after it has cooled down. Such liquids are flammable.
4. In order not to damage the surrounding surfaces, they are covered with matter.

You can enhance the wash effect if you create a steam effect. After applying the composition, the surface is protected with polyethylene. However, cellophane and wash should not come into contact.

Conclusion

To get rid of the paint on the metal, you have to make an effort. It is important to take into account the features of the product, its thickness, as well as the type of coloring composition..

Most often, you have to resort to a combination of several methods. This is the only way to completely clean the coating of old paint.

If it's time to update the interior of your apartment, your house, and also if you want to give new life favorite items, then you need to think about what to do with those things that were originally painted different types paints.

Naturally, applying a fresh layer of paint material to an old one may not bring the desired result and a once-loved trifle, an old grandmother's chest, or even Entrance door look sloppy and completely unsightly.

Does the paint need to be removed?

Before you start the time-consuming and slow process of removing the previous coating, you need to decide whether you need to remove the old paint?

Well, if you are going to the surface where the old paint is, apply ceramic tiles, plaster, stick wallpaper or the old paint is cracked, the surface is uneven, streaked, bumpy, then by all means - this coating must be removed.

And if you are sure that only one or two layers of paint have been applied, the surface is even, not cracked, the color is more or less consistent with the next coating and the texture is oily, then with skillful processing, you can apply a new layer.

To do this, it is necessary to sand the previous layer with sandpaper, thereby removing tubercles and minor irregularities, then treat with an alkaline solution (either bought at a hardware store or soapy home cooking), make a primer (synthetic or alkyd primer), dry and now the surface is ready for painting.

Otherwise, when the multi-layer applied paint material is unknown, deformed from time and conditions environment and you plan to change the invoice and appearance over the applied layer, then the restored thing will lose its freshness and attractiveness quickly enough.

So, let's take a look at how and how to remove layers of old paint? To do this, first of all, you need to see what surface it is applied to: concrete, brick, wood, metal; or on building mixtures - drywall, plaster. Secondly, try to understand what kind of paint is used.

Be sure to try scratching a small area with a spatula to see how many coats have been applied. After the study, you can start choosing a method for cleaning the surface.

In fact, there are not so many cleaning methods, so if you approach each method in detail, then the paint will be cleaned off without unnecessary unnecessary effort, and the surface will be properly prepared for renewal.

The main, frequently used methods used by professional builders:

• Through mechanical action.
• chemical solutions.
• Thermal way.

We will analyze each of the methods in detail, taking into account which surface needs to be cleaned. Thus, the reader will be able to easily determine by what method the old paint is quickly removed, to choose the most convenient and inexpensive method for himself.

Through mechanical influences

This method includes two methods:

• mechanical - with the help of their hands and simple devices (axe, spatula, hammer, chisel, sandpaper, etc.)
• mechanized - with the help of a power tool (electric drill, sandblaster, grinder, puncher, etc.)

The mechanical method is the least expensive, but in the case of a large surface for processing, the multilayer nature of the material to be removed and the age of its application, it is distinguished by a very heavy use of physical force and a long procedure for removing paint.

But if you have a strong physical strength and not be limited by time commitments, then it is quite possible to use this environmentally friendly method. For example, use an axe.

This method is great if the room is small, not ventilated (kitchen, bathroom), before tiling or plastering.

To do this, chips are made on the surface of the wall with an ax, under right angle, then this part is filled with water and, after impregnation, the paint is peeled off by the sharp actions of an ax or a hammer with a chisel. This is a long and difficult process, and if concrete is painted with paint, this method is not effective!

Therefore, it is much easier to use a mechanized method, that is, using a power tool.

The advantages of this method are non-toxicity, as well as trouble-free removal of old paint, regardless of the age of application, texture and number of layers.

Cons - incredible noise, strong dustiness, a huge amount of garbage and a large number of time for processing. One of the most important points is the presence necessary tool:

• drill (including attachments) – perfect tool for scraping from concrete, it will remove the paint in small pieces with rough notches;
• more flat surface With required depth leaves behind a grinder (it is called a grinder), but it is extremely difficult for her to work, because soon, there is zero visibility from the cleaned material;
• more deep cleaning produced by a perforator with a nozzle (type of blade), this method is very noisy, but due to its efficiency it is often used;
• Another productive method is sandblasting, it lies in the fact that, under pressure, air with sand is supplied to the area to be cleaned, thanks to which the falling grains of sand clean the surface not only from paint, but also from any other contaminants, such as rust, if it is metal.

That is, this method can be used, but you need to understand that it is long, physically difficult and requires a certain skill.

Just remember to wear a dust mask and try to use power tools carefully to avoid mechanical damage skin.

Chemical solutions

This method is more perfect. At correct use With this method, there will be no more questions about how the old paint is removed. It is aimed at ensuring that any type of paint softens and can be easily removed with construction spatulas, brushes, scrapers.

In addition, chemical reagents can be prepared by yourself or bought in specialized hardware stores. The range of these products is quite wide (alkaline or organic type), only it is necessary to take into account the texture and age of the paint to be removed.

The advantages of this method are the negligible use of physical force, ease of use, very fast response and for all surfaces and types of paints.

There are, perhaps, too many cons, but if you carefully use the instructions for using the reagent, correctly apply means that protect against certain influences, work in a well-ventilated area, then the result will pleasantly surprise you!

So, if you have purchased a chemical reagent, carefully read the instructions for use, wear gloves, a respirator, goggles, a suit that covers open areas body, allow the room to be constantly ventilated, or work outdoors.

Now evenly, using a brush (a roller is also suitable), apply the solution and leave for the required amount of time. After softening the layer to be removed, remove the surface with spatulas, brushes or scrapers. If the paint is partially left, repeat the manipulation again.

In addition to toxicity, this method is quite expensive. To reduce the cost of the process, you can use your own prepared mixtures.

For example, if the surface (floor) allows, you can moisten it with plain water and generously fall asleep soda ash, cover with wet rags on top, maintain the humidity of the treated surface for a day and then, the swollen paint will be easily peeled off under the action of a spatula.

Very often, inventive people use the composition of three parts of quicklime and one part of soda ash diluted in water to a density. This mixture is enough to apply for twelve hours and then in the same way, with a spatula, remove the softened paint.

Some others are trying to use the solution liquid glass. It is bought in ready-made, is applied to the surface to be treated, allowed to dry completely, and, due to the properties of this substance, the hardened liquid glass eventually separates along with the surface to which it was applied.

Thermal way

It is very often used for those surfaces and elements where there is glass or other fragile material - glazed windows and doors. To perform, you must have a building hair dryer. And then everything is nowhere simpler - with one hand the surface to be treated is heated to a certain temperature, and with the other, the heated paint is almost immediately cleaned off.

This is very important, because if you let the paint cool again, with each subsequent heating, it will become more and more difficult to remove it!

If there is no hair dryer, you can use a simplified method - using foil and an iron: the foil is placed on the surface, heated with an iron, and also, without allowing it to cool, is removed from the treated area.

Everything is very simple, but, as always, there are disadvantages:

• the processing area is very limited - it is quite small;
• if the surface is near lying sockets, wires and other melting elements;
• when overheated, resins may stand out, which will prevent a new layer of paint from being applied;
• oil-based paint emits toxic fumes when heated, and paint containing lead should not be heated at all.

So, if this method suits you, then be sure to perform it in a respirator, try to avoid burns and ventilate the room well.

How to remove paint from wood?

Given all these methods, will the question of removing old paint from a wooden surface necessarily arise?

Painted wood products can include plank floors, skirting boards, parquet, frames, and more, as well as small parts for furniture and items such as chests, caskets, etc.

Having carefully studied the methods given above, you can choose any, given that the surface of the tree is quite soft and rough objects - a drill, a puncher, violate the integrity of the surface of the product.

In the case when the paint has already peeled off and is moving away from the wooden surface, you can safely use the method, which includes the use of a spatula and sandpaper - mechanical.

The meaning of this work is scraping off the paintwork. If the surface allows, you can use a grinder using attachments with non-rough abrasive surfaces.

If the paint lies tightly on the surface, you can use the chemical method, only it is necessary to select a reagent for a particular breed of wood being processed. Before applying the substance, clean the surface of dirt and dust with a damp rag, then, in accordance with the instructions, use the product, carefully clean off the residue with a spatula.

The thermal method should be used with great care, because when heated, the structure of the wood is disturbed and the surface, being exposed to too high a temperature, is burned through!

But this method is quite effective for wooden surfaces, the paint quickly warms up, swells, bursts, after which it is quite easy to remove it.

How to remove paint from metal?

In addition, a hot topic, the removal of old paint from metal elements, surfaces, details, about the nuances when using different methods and their effectiveness. Naturally, use the previously presented cleaning methods, but in this case, it is necessary to take into account the thickness of the metal and its grade.

Any mechanical method using a power tool is considered very effective. It must be borne in mind that if the paint is peeled off a thin metal surface, then a neat, painstaking manual cleaning method is suitable, but sandblasting is considered to be the most effective. Sand knocks paint particles even from the most inaccessible places, without much damage.

For chemical method it is necessary to select a reagent for a certain metal surface and, further, in accordance with the instructions, clean the layers of paint.

Aerosols are very easy to use - they are presented in a large assortment in hardware stores.

The thermal method must be used very carefully, since it cannot be used on cast iron, brass, aluminum products, as well as decorative forged elements. So before using this method, consult with a specialist.

Now, with this knowledge, choose the cleaning method that suits you best, but in any case do not forget about the use of personal protective equipment. And believe me, using all these tips, you will get a positive result of your hard work!

Photo instruction on how to remove old paint

Paint removal is often required when performing repair work. The coating creates irregularities, and does not allow a new layer to hold on for a long time. There are several proven methods for removing old paint from walls. The choice depends on its composition, as well as the material of the painted surface. Before starting work, determine these aspects and select the best procedure from the information provided.

In years past, wall painting has been a popular choice for kitchens and bathrooms. In modern times, beautiful tile patterns have entered the design, which cannot be laid without cleaning the surface of old paint.

But there are situations when this is not necessary, for example, if the wall is later sheathed with drywall. In other cases, the coating is removed, since it does not contribute to the adhesion (adhesion) of the material with adhesives, plasters and other building compounds.

Choosing a paint removal method

When choosing a paint stripper for walls, consider the following criteria.

1. Type of dye- oil, acrylic or water-based. If the type is unknown to you, then you will need to select a removal method, experimenting on a small area. You need to start with the least laborious methods. It is also important to know the number of layers and the strength of their adhesion to the wall.
2. Painted surface material- concrete, wood, metal or drywall. For example, oil paint is the hardest to peel off of unplastered concrete.
3. Further front of work- painting, tiling, etc.
4. Event budget- for the purchase special means and fixtures.
5. Possibility of ventilation.

What you need

Also, the choice is influenced by the availability of the necessary tool. The following fixtures can be used:

• brush;
• personal protective equipment (respirator, goggles, rubber gloves, etc.);
• ax for notches;
• building hair dryer;
• chisel;
• putty knife;
• roller;
• iron scraper;
• electric drill;
• Bulgarian;
• chemical agent for removing paint from walls;
• water.

Important! Before the procedure, cover the furniture and the floor with a film so that they are not covered with construction debris.

Three main options for removing oil paint

The most problematic thing is to remove oil dye from non-plastered surfaces. But it is possible to do so. Today, there are three main methods that are characterized by laboriousness and duration of the process.

The use of chemicals

Removing paint from walls using chemical mixtures is carried out according to the instructions attached to the product. Prepare the solution, and spread it over the surface with a brush or roller.

Advice! Movements must be performed in only one direction.

Wait for the dye to soften. Remove it along with the wash using one of the tools of your choice:

• putty knife;
• scraper;
• brush with metal bristles.

The advantage of the paint remover option: cleaning speed.

Flaws:

• a specific smell that does not disappear for a long time;
• in addition to durability, it differs high content toxins;
• Causes chemical burns on contact with skin.
• rather big cost;
• needs special disposal.

Important! If the surface has been painted several times, then the product will not remove the coating the first time. It will not be possible to quickly remove the paint from the walls, since the application chemical composition will also need to be done repeatedly.

Follow safety rules during work - ventilate the room, use personal protective equipment. Allergy sufferers, children, pets and pregnant women are not allowed to attend. Make sure that the composition does not get on the skin. Put on overalls.

It is possible to clean the walls of old paint by other methods. If you need to work with a wooden floor, moisten the surface with water, then cover it with soda ash. Make the layer thick so that it covers the entire area. Wet the burlap and cover the floor. Wait a day, constantly maintaining the wet state of the material. At the end of the period, remove the layer using a spatula. This is easy to do, as it will swell from dampness.

The next method is a mixture of potassium carbonate with lime. The first component can be replaced with soda ash. It will take 400 g. Stir this amount into 1.2 kg of quicklime, and apply to the surface. Wait 12 hours before cleaning the wall of paint.

Another way is to use liquid glass. Lubricate the coating, let it dry and remove the silicate film along with the peeling paint. The procedure may need to be repeated several times.

cleaning chemical method also suitable for the following types of dyes:

• glyptal;
• pentaphthalic;
• polymeric;
• nitro.

For a small area, you can use solvents.

Heat treatment

In this situation, a building hair dryer will help. Heat the surface until the dye softens. Next, you need to remove the paint from the wall using a spatula or any other scraper. If a special hair dryer is not available, do not use a regular one. It is better to heat the coating with an iron, after covering it with a large sheet of foil. At the end of the work, wash the wall, clean up minor defects and wipe with a swab dipped in solvent.

This method is suitable for those places where there should be no vibration and shock (where there are window frames, glazed doors, etc.). This method is not used where wiring is located, or there are decorative elements damaged by high temperatures (for example, plastic).

Main disadvantage thermal method cleaning walls from paint - the evaporation of toxic substances when it is heated, as well as the accompanying specific smell. Safety measures include working exclusively in ventilated areas. In addition, you need to use personal protective equipment for the respiratory organs.

Types of mechanical methods for dismantling paint

This option will suit anyone who is worried about toxic emissions from other types of wall treatment when removing old paint. To do this, use a notch with an ax. The process has the following characteristics:

• no harm;
• cheapness;
• not traumatic;
• duration of work;
• laboriousness.

The sequence of actions is as follows:

• make notches using a tool;
• spray the painted surface with water;
• wait for it to be absorbed;
• scrape the old paint off the wall with an axe.

Important! If you choose the right angle of the blade, this will increase the efficiency of the work, as well as the speed of its execution.

This option is suitable for poorly ventilated rooms. It is used in small areas, as a lot of physical strength is used to work. It is often used where tiles will be laid in the future, since the resulting unevenness contributes to better adhesion of materials.

Interesting! The surface is sprayed with water to reduce the amount of dust generated in the process.

To tear off the paint from the walls, if it has already begun to peel off from old age, you can use a spatula or a chisel. This is also a laborious method, but distinguished by cleanliness. It is suitable for wooden surfaces, as well as places for sockets, baseboards, pipes, etc. In the process, you must have emery, which will be required to sharpen the tool.

Electromechanical method

This method is suitable for removing old paint from concrete walls, as it differs high performance which makes the job easier. To do this, use a grinder with a wide grinding wheel with an abrasiveness of at least 40, but be prepared for the fact that a lot of dust will be generated in the process. After a minute of processing, it is necessary to wait 20 minutes until the dust settles. Now on sale you can find models equipped with a vacuum cleaner, which facilitates the procedure and makes it cleaner.

Also, a nozzle is used for work, created like a brush from cutting steel wire.

You can also take a puncher with special nozzles. There are two options for removing paint from the walls in the bathroom and other rooms. In the first case, chains are taken as nozzles. This method is suitable for any surface - wood, metal or concrete.. It is characterized by efficiency and low cost. Rust is removed in the same way.

For the implementation of the procedure, chains of two types are taken:

• paint stripper;
• 13 link configuration.

Features of this paint stripping tool:

• the thickness of the link must be at least 5 mm;
• center link rotates 6 links on each side;
• the basis is a 6 mm bolt;
• the drill should rotate to the left;
• after putting on the chain, tighten the nut firmly to keep the fixation throughout the work.

If the extreme link flies off on one side, then it will also need to be removed from the opposite side so that there is a balance. Work continues until at least three links remain with each of them.

Important! When cleaning, the paint from the walls will fly off in pieces, so you need to protect the body from mechanical stress.

In the second method of working with a perforator, brick crowns are used as nozzles.

The electromechanical method is rarely used on painted wood, as it is easy to damage the surface with a tool. To work, you need to have special skills.

Water based dye removal

In this situation, you can quickly remove the paint from the wall, since most of them are not waterproof. To do this, moisten the roller with warm water, and treat the surface. You can also use soap solution. Leave it damp for 10-15 minutes, then clean the area with a spatula. You may need to repeat the procedure, and even use a metal brush. If this does not help, then use the methods indicated for removing the oil dye.

Advice! Process small areas to keep an eye on their moisture content.

Acrylic paint removal

Suitable for removing acrylic paint metal brush and coarse skin. Wear rubber gloves to protect your hands during the process. If the purchased paint is of high quality, then it will be more difficult to remove it. If the easy method doesn't work, use the instructions for removing the oil colorant.

Advice! If the surface covered acrylic paint, in the future it is planned to paint with the same material, then the previous layer can not be removed if it has retained its smoothness.

What not to do

• the thermal method using open fire is too flammable;
• chemical wash - not used in unventilated areas.

Regardless of the choice of method for cleaning the walls from paint, do not forget to use personal protective equipment. In any process, you will be exposed to the following negative factors:

• dust;
• toxic substances;
• small particles of flying coating.

The most important thing to protect is the respiratory and visual organs.
