Before painting any surface, it is necessary to carry out preliminary preparation. It includes removing dirt, cobwebs, insects from the surface, as well as removing paint, sanding (for wood surfaces) and puttying.
The most important step is the removal of the surface coating. The left old paint contributes to the appearance of cracks, flaking of the new coating, and a violation of the aesthetic appearance. Consider the most common paint removal methods that you can use on the farm:
- thermal;
- chemical;
- mechanical.
The use of one of the methods depends on the type of paint applied, as well as on the material of the surface to be cleaned.
thermal method
The most effective method for cleaning wooden surfaces from paint and varnish is the heat treatment method. With the help of a building hair dryer or burner, the old surface is heated to the melting point. The paint softens and peels off, after which it is easily peeled off with a hand trowel. The advantage of this method is that even thick layers of paint can be stripped quickly and efficiently.
The processing method is only suitable for wood, and in some cases for metal. It is ineffective for plastic, the latter begins to melt and deform at high temperatures. This method is of little use for the treatment of painted concrete, stone or plastered surfaces. A significant drawback is the release of volatile toxic substances when the paint is heated.
Chemical way to remove paint
You can also remove old paint with special tools, which include chemical solvents. They are produced for the removal of a specific coating and are based on acids, alkalis and organic polar substances, such as acetone or gasoline. There are also solvents with a universal composition, but their effectiveness is lower.
After applying the solvent to the surface, it must be left for 15-60 minutes. The time depends on the type of old paint and the thickness of the applied layer. The required time of contact with the surface must be indicated on the packaging. During this time, the old paint will begin to soften and can be easily removed with a hand trowel.
The chemical method is suitable for cleaning most surfaces:
- tree;
- metal;
- plastic and linoleum;
- MDF and glass.
The method of removing paint by mechanical action
Mechanical paint stripping methods include cleaning with hand or power tools. The most common tool for removing paint from large surfaces is a grinder or an angle grinder (angle grinder). If a grinder is used, instead of a disk, a special wire brush (brushing) is fixed on it. You can also use a drill with a metal nozzle. This method is suitable for stripping wood and metal from oil paints.
To clean concrete, stone, plastered walls from water-based paints, surface grinders with coarse-grained sandpaper, with a grain size of 250-600 microns, are used.
The manual method of removing paint with a spatula or scrapers is also referred to as mechanical methods. This process is quite long and laborious, but the most affordable. Removing the paint by hand will not give you a completely clean surface, so use it in combination with other methods, or at the stage of completion of preparatory work. The advantage of the manual method is the ability to remove any paintwork.
Sooner or later, every owner of an apartment or his own house comes to the conclusion that the time has come. Whether it's a cosmetic procedure that aims to create a new and fresher interior, or it's a major project involving remodeling and the use of unusual finishing materials, you can run into a number of challenges. Especially if you intend to do all the work yourself. One of the most common problems is the removal of the old decorative coating from the walls. If the old layer sometimes itself begins to crumble and fall off in whole layers, or can move away from the walls in whole stripes, then it will be much more difficult to cope with a layer of old paint. And before a certain type of finish, it must be removed without fail. To make this task easier, you need to know effective ways to remove paint from the wall.
When should the old paint be removed and why?
It's no secret that 15-20 years ago, the favorite finishing materials of all builders were paint and. Especially often you can find painted walls in the bathroom and toilet, in the kitchen or in the hallway. Builders with a creative approach to business often decorated the walls with flowers and boats. Unfortunately, such a print ceases to touch when it becomes necessary to get rid of it. It's one thing when the old paint is already peeled off and can be easily removed with a usually spatula. And it’s quite another when there are several layers, they are applied conscientiously and hold on with enviable strength. Assuming the full severity of future work, many give up and the thought creeps in: “ maybe well him?». 
We hasten to please you - in some cases old paint really no problem for further finishing work. It all depends on their type:
- For example, if we are talking about a bathroom where there is a need for further installation, you can simplify the task with the help of drywall. Some walls are so curved and have such obvious differences that it is sometimes really faster and even more economical to level them with the help of fixed profiles than with plaster. Plus, you get a surface with excellent adhesive performance;
- For fixing plastic or other wall panels, old paint will also not become an obstacle;
- If you plan to repaint and the surface of the walls allows you to do without their alignment, you can apply a layer of a new coating on top of the old one. Provided that it does not swell, does not peel off, holds firmly and does not have cracks. In some cases, individual areas of peeling paint can be removed, and the resulting unevenness can be filled with finishing plaster. But please note this paragraph applies only to situations where applied acrylic paint on old acrylic, or enamel paint on old oil. In the case of applying acrylic or water-based paint on old enamel, these compositions simply will not “lie down” on a glossy surface. Perhaps when applied, it will seem to you that the paint is still evenly distributed on the surface and everything worked out, but after drying you will find separate islands of a new color that are interconnected by thin cobwebs;
- They will allow you to avoid the need for an old coating before tiling the walls and modern tools. For example, a primer called "concrete-contact" and other interpretations of the name with a similar meaning, promise good adhesion after drying even with a completely smooth surface. Even glass appears on the list, and on the Internet you can find a lot of video evidence.
- If you plan to apply wet plaster and other compounds to the walls, such as, for example, paint must be removed. Plaster just won't "stick" to a smooth surface. The paint has a minimal ability to absorb liquid, so the usual primer simply cannot penetrate its structure and ensure adhesion. And under the weight of heavy wallpaper sheets impregnated with glue, the paint can simply move away along with the freshly glued wallpaper. Even if at first glance, it seems that she is holding tightly.
What to consider when choosing a paint stripping method?
Before embarking on labor-intensive and lengthy work, it is necessary to understand what we are dealing with and try to choose a method that will nevertheless prove to be most effective at the lowest cost of labor and time. To do this, you need to pay attention to five determining factors:
And it’s best to “try it on the tooth” and on a small section of the wall try to remove a piece of paint with each of the methods in turn, starting with the simplest ones.
Mechanical methods of removing paint
Usually the first attempt is to remove the coating mechanically. It should be noted right away that these methods are the most time-consuming, but at the same time one of the most affordable. A variety of tools are used, ranging from the simplest. Before starting work, it is necessary, if possible, to free the room from furniture or cover surfaces with a film, which must remain clean and free of dust and paint particles. Let's consider in more detail.
No. 1. With a spatula
This is the very first tool with which there is a desire to scrape peeling paint. A spatula will definitely be found in almost any home. Advantage method lies in the complete absence of dust and the fact that it is possible to remove paint even in corners and other hard-to-reach places - around. To shortcomings include the relatively slow speed of work, the need to exert considerable effort and the inability to cover a large surface area in one approach. During operation, small particles of paint break off and can get into the eyes, thereby injuring them. Therefore, be sure to think about personal protective equipment. This rule applies to absolutely all methods of removing the old coating. 
No. 2. At aid chisel and hammer
When you have reached a section of the wall where there are no cracks and blisters of paint and the spatula is already powerless, you can try to remove it with a chisel. It does not bend during operation, unlike a spatula, and if necessary, you can tap with a hammer on its handle. Periodically it is necessary to sharpen the tool. It will quickly dull from constant friction on a hard surface. 
Number 3. With an ax or kirochki
This method is incredibly labor intensive. You will have to swing the ax for a long time, so we advise you to choose a tool that is not too heavy. However, it should not be too sharp. The essence of the method is to apply notches to the wall. The blows must be directed tangentially to the wall. The length of the notches can reach several centimeters, and they should be located at a distance of no more than 10 mm from each other. Only on such a surface will the adhesive composition lie quite reliably. But the main flaw The method actually lies a little deeper. Think about how many blows to the wall you will have to inflict and understand that each of them will gradually violate the integrity of the base that you want to get rid of the hated paint. Not all walls can withstand such torture and remain strong and reliable. 
No. 4. With a drill with various nozzles
This way can be called optimal by the ratio of indicators of speed of work and safety. Plus, due to the fact that this is not the heaviest hand tool, your hands will get much less tired during work. Safety is achieved due to the fact that the work is carried out at low speeds. Before you start, be sure to check the performance of the tools - if the wire is broken, if the cartridge is holding well, if the device sparks. In order not to be distracted by trifles, make sure that the cord is long enough to move freely along the entire length of the room, use an extension cord. Be sure to wear a protective mask, closed clothing and shoes, and a hat. Never leave sleeves unbuttoned or wear gloves. When working with revolving tools, their use is unacceptable - the reliability of fixing the tool in your hand worsens and you simply cannot hold it. In the best case, the instrument itself will suffer if it falls, in the worst case, it will injure the performer.
Now you need to adjust the speed - turn on the drill without a nozzle and select the minimum mode. Now fasten the nozzle, tighten the cartridge well and get to work. It is necessary to touch the wall only with the surface of the nozzle and not move too quickly. Most often, a metal brush is used. But in practice, it is less effective than a nozzle in the form of several connected chains of 3-4 links with a washer at the ends. In addition, sometimes the metal bristles come off and can dig into unprotected areas of the skin; 
No. 5. With the help of a grinder
This method can be called the fastest and at the same time the most dangerous. for high speed tools. In the absence of skills to work with it, you can be seriously injured. No one is immune from the destruction of the disk during operation, the fragments of which fly at incredible speed in different directions. The disadvantages include a high level of noise, and a huge amount of dust. Work is usually carried out using a wide range. 
Summing up we can say that mechanical methods are suitable for removing absolutely any type of paint - both acrylic and oil. It’s just that some of them will need to be moistened periodically, and then also removed with a spatula, a metal brush or a power tool.
Thermal methods
Methods for removing an old layer of paint using elevated temperatures are also refer to extremely dangerous. When carrying out such work, reliable protection and concentration are required and, of course, experience with the following tool. There are three commonly used methods.
No. 6. We use a regular iron
For a coating that is no longer held in the most reliable way, the method of exposure to temperature is suitable with help ordinary iron. Through a sheet of thick foil, you can food, the desired area is well warmed up, and then the softened coating is removed with a spatula.
No. 7. We use a building hair dryer
Similarly, only much faster, you can "melt" the paint with help construction hairdryer, and then remove with the same spatula or other convenient scraper. 
No. 8. Blowtorch method
Sometimes use a blowtorch. Or in other words, a burner that runs on kerosene or gasoline vapors. One liter of fuel is on average enough for continuous operation for 20-50 minutes. The flame must be brought as close as possible to the paint and carefully watched. When the paint begins to melt but not burn, you can scrape it off the wall.
All thermal methods are required accompanied by a sharp and unpleasant smell, which appears during the heating of the paint. Therefore, it is categorically not recommended to work in unventilated areas. Also by no means it is forbidden warm the places where they pass or those where there are wooden mortgages in the wall.
Chemical methods
Methods for removing old coatings using chemicals can be called least labor intensive. All you need to do is to carefully distribute the product on the surface, let it work on the paint for the recommended time, and then remove the softened coating. 
No. 9. Ready-to-use paint stripper
The time interval is always indicated on the packaging, as well as the recommendations for use, which we advise you to follow in strict order.
- All chemicals have pungent odors and are very aggressive. Be sure to work with gloves and a respirator, and for the duration of the solution, it is better to leave the apartment altogether, opening the windows for ventilation;
- Also, after finishing work, you can’t just take and pour the rest of the solution into the sewer. The chemicals are very corrosive and must be be disposed of properly. This is also mentioned on the packaging or in the instructions;
- It can also scare price such tools, but believe me, after you try to remove the paint with a spatula, ax or grinder and none of the above will give the desired result, you will not want to save. Often one liter of solution is enough to remove paint from the walls of a bathroom and toilet of standard sizes;
- Pay attention to the fact that some compounds may be intended for use only on horizontal surfaces.
AT component dependencies basics ready-made compositions are:
- Acid - based on hydrochloric or phosphoric acid;
- Alkaline - based on salts of various origins;
- Organic - which do not contain any salts or acids.
For removing old paint from stone surfaces most suitable are considered acid-free. 
By release form solutions can be in the form:
It is not difficult to choose a composition for a certain type of paint. In order not to make a mistake in choosing a wash, it is better to buy universal solutions that are suitable for removing any type of paint. For example:
No. 10. How to make a wash with your own hands?
You can still try to save prepare a wash for paint on one's own:
Usually, the above methods do a good job of either removing a newly applied or dilapidated coating. For strong layers of paint, it is better to use ready-made, special washes.
Wash application technology
When the choice of a suitable remedy is made, it's time to deal with the right technology his application:
That's all, your walls are ready for further transformation. If one of the above methods did not give the full effect, try combining it with other methods. By and large, they are all suitable for removing any kind of paint.
Sooner or later, every owner of an apartment or his own house comes to the conclusion that it is time to make repairs. Whether it's a cosmetic procedure that aims to create a new and fresher interior, or it's a major project involving remodeling and the use of unusual finishing materials, you can run into a number of challenges. Especially if you intend to do all the work yourself. One of the most common problems is the removal of the old decorative coating from the walls. If the old layer of plaster sometimes begins to crumble and fall off in whole layers, and the old wallpaper can move away from the walls in whole strips, then it will be much more difficult to cope with a layer of old paint. And before a certain type of finish, it must be removed without fail. To make this task easier, you need to know effective ways to remove paint from the wall.
When should the old paint be removed and why?
It's no secret that 15-20 years ago the favorite finishing materials of all builders were paint and paper wallpaper. Especially often you can find painted walls in the bathroom and toilet, in the kitchen or in the hallway. Builders with a creative approach to business often decorated the walls with flowers and boats. Unfortunately, such a print ceases to touch when it becomes necessary to get rid of it. It's one thing when the old paint is already peeled off and can be easily removed with a usually spatula.

Cleaning walls from old oil paint is a rather complicated and time-consuming process.
In some areas, the coating swells and falls off, but in some places it holds very tightly and is not always amenable to the action of an iron brush or scraper.
How to remove old oil paint from walls at home? The best ways to do this are discussed in the article.
The amount of time and effort spent on removing the composition from the surface directly depends on the chosen method of dismantling. A large number of superimposed layers greatly facilitates cleaning.
The time spent on removing the paint also depends on the material on which the composition was applied. With porous, loose plaster, the paint is removed more easily, but you have to suffer.
Exists . You can clean the surface with:
Mechanical impact
The process of cleaning walls from oil paint by mechanical means is the longest and most laborious, but does not require any financial costs.
This method is ideal for subsequent tiling of walls or leveling them with plaster, since adhesive and plaster mortars adhere perfectly to a rough surface.
The essence of the mechanical method of cleaning walls is to scrape and chip off the paint from the surface of the walls.
How to remove with an ax?
To clean the walls with this method, the main tool is an ordinary ax.
The purification process takes place in several stages:
So that the water does not have time to dry, it is better to wet and clean the surface in small areas.
How to clean with a spatula or chisel?
This method is suitable for removing paint in hard-to-reach places and corners, as well as when the oil composition is lagging behind the walls. To facilitate the work, you can use a hammer, which should be hit on the handle of a chisel or spatula. The surface to be treated must also be moistened with water.
When working in this way, the tool should be sharpened periodically, as it quickly becomes dull during such work.
The mechanical method of removing oil paint from a surface requires physical endurance and extreme caution when working with construction tools. However, this method does not require any financial investment and is safe for health.
thermal method
The oil composition applied to the walls softens significantly under the influence of high temperatures. With thorough heating of the surface, the paint can be removed with a conventional spatula.
For thermal cleaning, a building hair dryer is used.. At the same time, a small area of the surface is subjected to high temperatures and the paint is removed until it has hardened again.
In the absence of a special tool, you can use a regular iron. The surface should be heated through a sheet of foil.
The thermal method is not recommended for use in areas with electrical wiring, on surfaces made of plastic and PVC. Walls should be treated in rooms with good ventilation, with the use of protective equipment for the respiratory system. Under the action of high temperatures, the paint releases harmful substances.
It is strictly forbidden to use a blowtorch, gas burner and other sources of open fire to soften the oil composition, as this is unsafe and can lead to a fire. Especially if the surface is made of wood.
Electromechanical
The principle of this method of removing paint is similar to mechanical. Instead of an ax or a chisel, a power tool is used, which greatly facilitates the work..
The oil composition is removed using a drill, puncher or grinder with special nozzles: an abrasive wheel, a metal brush, a brick crown.
The order of work when using the electromechanical method:
The advantages of this method are the rapid cleaning of large surfaces, the minimum expenditure of physical strength.
The disadvantages of the electromechanical method include:
- loud noise when working with the tool;
- a large amount of small debris and dust;
- the impossibility of removing paint in hard-to-reach places;
- the need for a sufficient supply of nozzles, as they wear out quickly.
How to wash off with chemicals?
Washing off the old finishing material with chemical solutions is much easier and easier than scraping with building tools.
There are many special tools for . They include solvents, acids and other preparations that soften the coating. After applying the mixture to the wall, the paint is easily removed with a scraper or spatula.
The removal process involves strict adherence to technology:
Sometimes you have to resort to re-washing. Painted walls in several layers may not be cleaned the first time.
After completion of work, the removed paint with a chemical composition should be disposed of. Do not allow the mixture to enter domestic sewers or the ground.
The big disadvantage of using the chemical method is:
- danger of getting poisoned by volatile substances,
- get a burn of the mucous membrane, skin.
It is necessary to carry out work using special washes for oil paint in goggles and gloves. Apply chemicals only in rooms with good ventilation. The smell from the drugs may not disappear for a long time, so you should not stay in the repaired room for a long time.
Another significant disadvantage of the chemical method of removing the oil composition is the high price of the drug, which is applied to the surface. Especially if you need to process large areas.
Features of removing old paint
In order for the process of removing the old composition to be easy, it is necessary to choose the right cleaning methods. With a competent approach to work, the paint will quickly fall behind the walls, and the surface will not be damaged. Always consider the type of surface on which the paint is applied.
It is much easier to remove paint from walls if it is applied in several layers. If the composition is applied in one layer on a concrete surface, then there is a long painstaking work ahead. In this case, the chemical method of removing paint is best suited.
The choice of cleaning method depends on the presence of a layer of plaster under the composition.. If not the wall itself is painted, but the bonding layer, then the removal process will be much faster. If there is plaster on the wall, then the mechanical method of removing paint from the surface is best. Before starting a new wall decoration, they should be leveled.
Common mistakes in the cleansing process
With the wrong approach to removing oil paint from walls, you can harm your own health, as well as spoil the surface being cleaned.
In no case should open sources of fire be used in the thermal method paint stripping.
When using a chemical wash, the room must be well ventilated or ventilated. Incorrectly selected paint scraping tools can damage the surface to be treated.
Do not neglect the means of protection in the process of performing work:
- glasses,
- gloves
- respirators.
Subject to all safety rules, the likelihood of harming your health is excluded.
When using the thermal method, the wall heating from the bottom up will be the most effective. A well-heated strip can be easily removed with a spatula. The composition will melt under the influence of high temperatures, so you should use a napkin to clean the spatula.
Do not use chemical washes and clean the paint with solvents in residential multi-storey buildings. Toxic fumes from drugs can adversely affect residents of neighboring apartments.

Conclusion
Chemical and thermal methods for dismantling the old oil composition from the walls are less laborious, do not damage the surface to be cleaned, which subsequently saves on putties and other mixtures.
However, such methods are the most dangerous for human health. That's why before starting work, you should carefully consider which method will be most appropriate.
