Very good news for site users. Another video is ready on the topic: "How to shoot old paint". Everyone probably faced this. Since before each planned repair work, before proceeding with the installation of walls, windows, doors, etc., we need to prepare the base, namely, clean off the old paint, level the required surface and then proceed to necessary action for restoration or decoration.
Therefore, in order for you to have in your arsenal good way peel the paint off the surface, I suggest watching this video. Since the plot takes place without additional comments behind the scenes, I will try to comment on the text in the article below.
To start work, you need to prepare necessary tools, which we will use, namely this: a building hair dryer and a special scraper. With which we will remove a layer of paint. These tools are shown in the photo.
also in preparatory work includes post-repair provision, which means that the entire coat of paint will fall directly onto your flooring, and some of the paint that we have peeled off the surface after exposure to a building hair dryer will be in a soft state. Therefore, in order to avoid damage, we floor covering, on which the paint will fall, cover it with either a board or a cloth.
Let's go directly to the process itself:
On the video "how to remove paint from the surface", we see how the removal process takes place. You choose the method of hot air action on the object and removal of melted paint from the surface. Since the speed of your work depends on it.
We turn on the first speed of the hair dryer, wait a minute until it warms up and then turn on the second speed, after which the hair dryer starts to heat up the surface where the old paint is located more strongly. After the hair dryer has heated the paint to the state we need, we remove the paint with a special scraper, which is shown in the photo in right hand. We can find out to what state we need to heat up by observing the paint itself, namely, it should be covered with bubbles. After that, we boldly begin to peel off the paint, and direct the hair dryer to another area. Use only cloth gloves. It is also advisable to wear protective goggles.
Different paints are removed in different ways: some are easier, others sometimes even baffle experienced builders. It all depends on the type of paint and the surface on which it is applied. In order not to waste time searching for information and various experiments please study this article carefully. In it we will consider all possible ways how to remove paint, describe their advantages and disadvantages, do not forget about security measures, and also mention the ways in which smart person should not be used at all.
Painting the walls of kitchens and bathrooms was very common in interior design during the Soviet period. Therefore, many of us are still faced with the need to remove paint from walls, floors and ceilings, for example, before leveling them or before laying ceramic tiles. Should it be removed or can the floor and walls be restored over the painted surface?
It all depends on what you plan to do next. If you decide to sew up the wall with drywall, you can leave the paint on the wall. But in most cases, you still have to remove old paint from walls and ceilings, since the painted surface has adhesion (adhesion) to tile adhesives, cement plasters and any building mixtures practically zero. So if you decide to apply plaster on top of the paintwork - the joy of the repair you have made will not last long.

How to choose best way paint removal?
Four factors influence the choice of one or another method:
The paint itself can be of several types: water-based, acrylic and oil. The hardest thing to remove is oil paint. concrete surfaces. Therefore, we will take a detailed look below on how to remove the old oil paint.
Of course, you may not know what kind of paint is on the walls of your home. In this case, you still have to experiment a little with the removal methods on small plot walls. Try the least time-consuming, gentle ways first.
The paint can be applied to metal, wood, drywall or concrete. The most difficult thing is to remove oil paint from bare, unplastered concrete from the ceiling.
Depending on the removal method you choose, you may need the following tools and materials:
It is especially difficult to remove oil paint from walls and ceilings unless they have been previously plastered. In general, there are not so many ways to remove oil paint. To come up with something new, completely harmless, fast and not requiring much effort, unfortunately, science has not yet succeeded. So let's look at all possible options with their pros and cons.
In general, all existing ways paint stripping can be divided into three groups:
The essence of the method: prepare a chemical solution for removing paint according to the instructions, apply it to the surface with a brush (it is better to move in one direction) or with a paint roller, give time to soften the paint and remove the paint with a remover with a spatula, a metal scraper or a brush with a metal bristle. This method is the fastest, but the smell can remain for a long time. Also note: if the paint has been applied in several layers, the use of a wash does not guarantee perfect removal immediately. It may need to be applied in two or three steps.
Removing paint with chemicals- a method that has a lot of disadvantages. First, it is highly toxic and has a sharp specific persistent odor, secondly, it can cause burns if it comes into contact with the skin, thirdly, it requires special disposal (in no case into the sewer), and fourthly, it is not cheap.
If you still decide to use chemistry, be sure to follow the safety rules. Work with reagents only in well-ventilated areas using personal protective equipment (respirator, goggles, gloves), pregnant women and children should not be in the room. It is necessary to completely protect all parts of the body from chemicals. this mixture of acids and solvents is very aggressive and contact with it will lead to disastrous consequences.
You can also try the following methods. To remove paint from a plank floor, moisten the boards thoroughly with water and cover with a thick layer. soda ash. Cover it all with damp burlap and leave for a day without letting the burlap dry. A day later, you can easily clean the paint swollen from dampness with a spatula.
You can also remove old paint with a mixture of potassium carbonate and lime. Mix in water 1.2 kg of quicklime and 400 g of potassium carbonate (or soda ash) until thick. Apply the mixture to the surface and keep it for 12 hours. After that, the old paint will be removed easily.
Another option is to remove oil paint with liquid glass. Lubricate, let dry well. The silicate film should begin to peel off along with the paint. Repeat the procedure several times.
Removing paint building hair dryer- a method known for a long time. Heat the painted surface with a building hair dryer until the paint softens and with a spatula (another scraper) clean off the soft paint from the wall, doors or floor. If there is no hair dryer, take a wide sheet of foil and heat the paint through the foil with an iron.
The method is not applicable in places where there is electrical wiring or there is decorative coating, which can be damaged by high temperature(e.g. plastic).
But this method is ideal for removing paint in places where vibration and shock are unacceptable (for example, glazed doors, window frames etc.) But a very significant drawback of heat treatment is the pungent smell of paint and the release of toxic substances when it is heated. Therefore, it is necessary to reliably protect the respiratory system and use this method only in well-ventilated areas.
Pay attention to physical properties paint, which, during chemical and thermal removal, releases strong toxic substances, the most optimal use is precisely mechanical method removal.
The well-known old grandfather method - laborious, slow, but cheap, non-traumatic and least harmful - notching the walls with an ax. To remove the paint, you will need, in fact, an ax, water and muscles. First, make notches with an ax, then sprinkle the wall well with water, wait a few minutes until it is absorbed, and clean off the paint with an ax. To work faster and more efficiently, you need to choose the right angle of inclination of the ax.
Most often, this method is used if further wall cladding is planned. ceramic tiles, since the adhesion of tiles to a non-smooth surface is the most ideal. Despite the fact that the method is laborious and slow, it is quite acceptable when you need to process small area, and is almost ideal in poorly ventilated areas.
To speed up the mechanical removal of ink from concrete wall, facilitate your work and increase its productivity, we recommend using mechanized methods.
You can use a grinder with a wide range. With such cleaning, the dust will be very, very much: after a minute of work, you will have to wait twenty minutes until the dust settles. But today there is already excellent new equipment with a built-in vacuum cleaner that allows you to remove paint from the wall as cleanly as possible. Watch video:
There are two more ways with nozzles for a puncher.
The first method is to use a chain as a nozzle on a drill. This is a fairly effective and cheap method for removing paint and rust from concrete, wood and metal surfaces.
It is possible to use chains of two configurations. The nozzle of the first configuration, the so-called paint remover, is shown in the photo and in the video below.
The nozzle of the second configuration is a chain of 13 links with a link thickness of 5 mm. The center link rotates 6 links on each side. A 6 mm bolt is used as the basis. Put on the chain and press it well with the nut. The drill turns on by turning to the left.
If the extreme link flies off on one side, it is necessary to remove it from the other side for balance. You can remove the paint until there are at least three links on each side. Unlike a brush, which produces a lot of fine dust, the chain beats off the paint in pieces. You must be protected from mechanical damage.
The second method of removing paint from a concrete wall is to use a brick crown as a nozzle for a puncher.
Acrylic paint can be removed with a good metal brush or even coarse-grained sandpaper. This handmade so don't forget to wear gloves. If the paint is good, it will not come off well. In such a case, you can use the removal methods described above for oil paint. Keep in mind that if you plan to cover the surface again with acrylic, it will fit well on any acrylic paint even without cleaning.
Ways not to remove old paint:
And remember. Whatever method you choose to remove the paint, be sure to use personal protective equipment. This is especially true for the respiratory and eye organs. Indeed, when cleaning surfaces from old paint, you are exposed to several hazardous factors at the same time: dust, toxic chemical substances And small particles paint flying off the wall.
Surely, many people in their lives had to remove old paint from various kinds of surfaces, while this procedure can not always be called the simplest and easiest. First of all, removing the old paint coating requires a lot of work and patience. Fortunately for today this problem almost completely solved, since such an important tool as a building hair dryer appeared. You can buy a tool of this kind today in almost every hardware store.
In turn, the building hair dryer does an excellent job of removing old paint, as well as many other difficult tasks. It is worth highlighting the advantages of using this device separately. It should immediately be said that in addition to the advantages of using technology, the article also describes little secrets, regarding how to properly and effectively work with a hair dryer.
They are used in numerous ways in the construction site. For example, with its help, you can simply dry a new wallpaper coating or solder non-refractory types of metals.
It is worth dwelling separately on the process of removing the old paint coating using this unit. A building dryer is the ideal tool for this kind of work. In this case, the paint coating after a while begins to be removed from the surface during the passage of hot air. Using this method not only speeds up the entire work process, but also guarantees where top scores eventually.
As for the very procedure for using the device, everything here is not as complicated as it might seem at first glance. Even a novice builder can work with it without any special knowledge and skills. And if you have ever used an ordinary household hair dryer, then when working with a construction analogue, you will not feel a strong difference. It is worth noting that the work between these two devices differs only in the temperature of the outgoing air. Of course, this indicator is much higher for a building hair dryer, and therefore it is worth taking care of additional protection for hands in advance so that you do not get burned when working with the device. Ordinary cotton gloves may be suitable for this purpose.
In the process of removing old paint, in addition to the device itself, it is additionally worth using a spatula or some kind of additional scraper. In order for the old paint to move away from the surface faster, adjust the temperature of the outgoing air in the appropriate direction.
If the paint layer is thick enough, then the temperature of the hot air jet emitted should be appropriate. It is worth warming up the surface directly in front of the scraper or spatula itself, while moving forward. If you work inside a building, then you need to take care of hourly breaks in order to ventilate the room. Otherwise, there is a risk of chemical poisoning arising from an excessive amount of vapors that appear during the heating of the varnish-paint material.
In addition, there are some tricks when removing old paint with a building hair dryer. Thus, if you use a spatula or a scraper together, then you should use only its sides. This is due to the fact that the side of the spatula is more blunt, and therefore it will remove the old layer more efficiently.
In addition, do not warm the surface too much. Otherwise, this can greatly soften the paint, making it difficult to clean off. In this case, it will simply begin to stick to the work surface. It is necessary to evenly clean the entire coating from soft layers, while carrying out successive and progressive movements with a spatula or scraper.
Often the beginning of the repair is complicated by the presence of an old layer of paint on the walls. To continue cosmetic procedures, you should carefully study all the nuances of how to remove old oil paint from the walls. Otherwise, further ennoblement of the premises will be impossible, and all the efforts made will turn into a series of failures.
Before you wonder how to clean the walls of paint, you need to decide whether to get rid of it altogether. In most cases, the walls were covered with dyes on oil based. If the relief of the wall remains even, without chips, falling off pieces and bubbles, and further procedures are not associated, for example, with applying wallpaper or a primer, then you can paint over the old layer.
The modern dye market provides a lot of reliable options. Paints based on water, silicone or mixed with acrylic adhere well to the surface, providing a secure fit. But even with the use of quality materials, the entire overlapping process will go down the drain if the surface was uneven.
In cases where it is necessary to carry out surface leveling work using putty, removal of old paint from the walls is necessary. This fact is confirmed by the poor adhesion of primers to paint surfaces.
Oil paints are the most difficult to lag behind the surface, and therefore the technology of getting rid of them is the most time-consuming. The more layers that have been applied, the easier it will be to clean. Much also depends on the material on which the dye was placed. Removing oil paint from porous plaster will not create any special problems, but you will have to think hard about how to remove paint from concrete.
Cleaning the walls of old paint requires some preparation. First of all, to remove paint from the walls, you will need the following set of tools:
How to remove oil paint from walls? There are three ways you can remove old paint from walls. It can be removed through the use of chemical solutions, increased heat, well, or mechanical impact. It remains to choose the most suitable method for removing paint from the walls, and you can proceed.
How to remove oil paint from walls? First of all, you can try the chemical method, in which a special wash is used. How to remove paint from walls quickly and efficiently? Everything is much easier than it seems. You only need to apply the solution to the hated surface and go about your business.
After a couple of hours, the chemical begins to act, and the paint softens. In the end, you just need to tear off the semi-soft substance. When using chemical washers, you can count on removing not only oil layers, they can also clean off acrylic paint.
But, despite the simplicity of the algorithm, this method has a number of disadvantages:
How to remove old paint without harm to health when using this method? Think safety! Work with chemical materials should be carried out only with full equipment in a respirator, goggles and gloves. Regardless of additional protection, wash off the remnants of chemicals after the procedure.
The room must be well ventilated. Children, allergy sufferers and expectant mothers should stay away from the poisonous source.
If you are wondering how to wash off oil paint, then modern market offers a wide range of raw materials. Some you can buy and some you can make yourself. For example, thanks to liquid glass the old dye is removed quite quickly - it covers the desired surface, which, when dried, is covered with a thin transparent film. Together with it, they easily peel off the old paint.
If the task arises, how to remove oil paint from the walls, you can resort to a home-made method. Paint remover is easy to make and does not require a large number of components. This will require quicklime in the amount of 1.2 kilograms and half a kilogram of calcium, mixed with ordinary tap water and applied to the desired object. These components will quickly remove layers of unwanted dyes. After twelve hours, the cleaning of the old paint will go off with a bang.
How to remove old paint from walls with a thermal method? This can be done by heating the dye with a hair dryer to an amazing temperature. This method has been tested by more than one generation and will definitely not let you down.
The technology is very simple: heated the paint with a hair dryer - took it off. Removing old oil paint will not be difficult, but it will take some time. When bubbles and bulges form on the surface under the influence of heat, the melted layer of paint is removed with a sharp spatula.
For the sake of exception, you can try using an iron through a layer of paper or newspaper. The iron is only suitable for a small thin layer, as it may not give a suitable temperature. Removing oil paint from walls with heat is great for areas near fragile materials.
However, this method also has its drawbacks. These include:
Don't even think about stripping lead paint off with heat! She has the highest toxicity. Vapors of such material instantly penetrate the body and cause irreparable damage.
On the video: removing old paint with a hairdryer.
How to remove old paint from walls mechanically? First you need to decide on the working tools that you have at home. This method is non-toxic, which makes it possible to clean kitchens, bathroom tiles and various indoor areas. It is divided into manual and mechanical with the use of electrically driven tools.
How to remove paint from walls manually? A method proven over the years will not require you to spend a lot of money. You just need to arm yourself with ordinary water and an ax.
First of all, serifs are applied with an ax along the plane of the paint, then it is wetted with water, which is better not to spare. Water should soak the surface for five minutes, after which the paint can be removed with an ax without any problems. They clean it with sharp movements, tilting the tool almost parallel to the wall surface.
For recesses and narrow places, as well as areas for sockets, baseboards and wires, a spatula or chisel is well suited.
Only such a tool should be wielded on a wooden surface. Since the active removal of paint will dull the tools, it is good to have sandpaper on hand, which can be used to sharpen a dull unit. The advantages include cost-effectiveness, safety (but with an ax it’s still more careful), and cleanliness. However, this is a long-term process that requires a considerable investment of physical strength.
How to remove paint from the walls in the bathroom and at the same time save your health, money and time? An electric drill or grinder will also help you with this. It should be said right away that when working with the latter, an incredible amount of dust is formed. After a minute of operation, the visibility of the room will be zero. This is very inconvenient both when working in the kitchen and in any other room. So best tool for removing paint - this is a drill with nozzles that perfectly beats off layers of paint.
The nozzles can be a special chain or grinding wheel, even better if it is framed with rigid wire.
How to remove paint from the walls in the bathroom with large layers? For large layers paint will do a nozzle with a chain that will rotate and knock out pieces of dried paint. However, if you clear concrete tiles, this nozzle will not work, its field of work is not rough plaster.
Most universal option- grinding wheel. It is convenient for them to tear off any materials and dyes, suitable for all coatings. This method, like the one described above, will also help peel the paint off the walls in the bathroom.
How to quickly remove old paint from concrete? Concrete should be given special attention, since such a surface holds the paint best. Plus, the painter who painted such a wall, most likely, did it in good faith, hoping to put a layer of paint on for centuries.
You should not resort to chemical methods cleaning and washing off the paint with solvents. In residential multi-storey buildings, toxic fumes will descend to the lower tiers, poisoning not only you, but also your neighbors.
Most The best way- removing paint from a concrete wall with an ordinary drill.
You can also use soda. Hands are protected with rubber gloves, and a small piece is covered for testing. After three to four hours, remove the old paint with a spatula. The paint is characterized by a long softening, but even small changes in its structure are a good sign.
The procedure can be repeated until cleansing is noticeable. Even if after such manipulation it is not possible to completely expel the coloring matter, this will be a good preparation for mechanical cleaning, with which everything is cleared pretty quickly.
How to remove paint from kitchen walls? IN kitchen areas increased dryness and temperature. Due to this, the paint rarely bubbles, which slightly complicates the process of washing it off. How to wash off the paint from the walls in this case? For this ritual, you can stock up on express gels. These are special washes that corrode the paint layer in a matter of minutes.
They should also be handled in protective clothing. Such a gel is applied for ten minutes, and then smoothly leaves with a spatula. A paint stripper like this is fast and effective.
There is another option than to remove oil paint. You can put an iron cord brush on a drill and walk it over a layer of unwanted paint. Since these nozzles are removable, they can be applied by hand, for very narrow or thin places. It will be dusty, but quickly and efficiently.
After any stripping of paint, the walls look gloomy and unpresentable. But, looking at the fruits of your efforts, you will be able to appreciate your own work and proceed to further repair work with a clear conscience.
Removing old paintwork The process is long and tedious, but necessary. Thick layers of paint on frames and jambs eventually cause windows and doors to stop closing properly. If you paint walls, floors, ceilings directly on top of old paint, you can never be sure that the decorative coating will last long enough. Old paint tends to peel off, which means it negates all repairs. Therefore, you need to remove the old paint!
There are two main ways to do this:
Regardless of which paint removal method you choose, remember to follow safety precautions. Work with toxic materials and paints in gloves and a respirator.
To remove fresh paint, a solvent is most often used that matches the type of paint - acetone, white spirit, solvent, etc. But in order to cope with outdated and completely dried paint, they are not enough, in this case complex solvents are useful - paint removers and destroyers .
washes- these are special chemical compositions designed to remove old coatings, hardened fillers, sealants and other materials. The wash is absorbed into the paint and destroys it - the paint swells and softens, after which it can be quite simply removed with a spatula, stiff brush, chisel or wooden scraper.
Choose an old paint remover according to the type of paint you want to remove and the base material on which this paint has been applied. Instructions for use are indicated on the packaging - read them carefully! Washes contain aggressive chemicals in their composition - acids and organic solvents that interact with the paint, but do not destroy wood, metal or other materials. Washes are toxic, so try not to lean over the surface to be treated, the room must be regularly ventilated during work. Most exterminators are not washed off with water. When opening a jar, remember the main rule of a chemist - keep it with the neck away from you so as not to accidentally inhale the accumulated vapors.
You can apply the remover or destroyer with a regular brush with natural bristles. It is desirable that the brush does not have plastic parts. When working with exterminating compounds, plastic spatulas and other tools should not be used at all. Many washes have a thick gel-like consistency, which allows them to be applied in a fairly thick layer, even on vertical surfaces. After the wash is applied, wait for the time required for the reaction, but do not allow it to dry completely, otherwise the whole work will have to start over. If it is not possible to remove the coating completely at one time, then the procedure should be repeated. Minor residues of paint can be cleaned with sandpaper.
Remember that you need to work with the wash very carefully. If the composition gets on other items, it can ruin them. Plastic or painted surfaces must be protected from accidental contact with washer and paint residues. Don't forget to cover the floor too.
If you have leftover wash, then it can be useful for cleaning and preserving brushes.
The second way to get rid of old paint is to treat the surfaces with hot air using building hair dryer (thermal gun). A building hair dryer is designed in the same way as a regular hair dryer. Inside its case is a filament coil and a fan. A building hair dryer is inexpensive, and in addition to fighting old paint, it can be used for drying, and for local heating, and even for welding plastic (a set of special nozzles is often included in the kit). Temperature and air flow rate are adjustable. So buying a building hair dryer in many cases can be a much more profitable purchase than using washes. Especially if you are renovating. an old house or an apartment.
Direct a jet of hot air at the paint. When it begins to swell, peel off and soften to the consistency of plasticine, remove it with a spatula or chisel. You will have to work directly in a stream of hot air, otherwise the paint cools quickly and loses its plastic properties.
Hot air treatment is good For wooden surfaces . The main thing is not to overdo it, so as not to bring the tree to charring. To Work with plastic surfaces be extremely careful, as the plastic can be overheated and irreparably damaged. The tool should also not have plastic parts (use metal spatulas with a wooden handle). A hair dryer is also not suitable for removing paint from metal, since metal has a high thermal conductivity and removes heat from the paint, preventing it from heating up to the required temperature.
Special care should be taken when working with a building dryer near wires, furniture, glass, wallpaper and other flammable materials. You can protect surrounding objects from heating with a sheet of plywood or thick cardboard. It is recommended to remove the glass from the windows, as they are very sensitive to temperature changes and can easily crack. Consider also that hot air lifts up, do not lean over the work area, keep your head at or below the level of the hair dryer. If the hair dryer nozzle becomes very hot, use stands and do not leave the hair dryer on unattended.
When heated, toxic fumes evaporate from the paint, so ventilate the room from time to time. If you are removing paint from furniture or, for example, from doors that can be removed from their hinges, then it is best to do this outside.
After the old paint is cleaned, the surface can be puttied, dried, processed
