Faded and cracked paint wooden frame, doors, log house and on any other cleaned wooden surface, which is present in the house, carries a certain charm of antiquity and comfort. But time and weather no one canceled, and the coating begins to crumble to the ground in pieces. It's time to go to the construction market for a new composition and update appearance ancient wood. But first, the old paint must be removed without damaging the wood. How to remove old paint from a tree, and tells the material of this article.

Before you pick up a building hair dryer, a brush with a chemical washer and read about how to remove old paint from a wooden surface, you need to know about the type of wood with which you will work. Some types of wood require more care than others. For good result on any tree, technology should be followed - it is correct to use means for removing decorative coatings.

It would not be superfluous to find out about the age of the wood, its operating conditions, climatic indicators, as well as other factors that have or previously had an impact on the painted wood.

Wood can last more than a dozen years only with proper, constant care. In some cases, wood exposed from the old paint layer will require treatment with protective agents, otherwise the new coating will not last very long.

Instrument preparation

Prepare your tools ahead of time. To remove you will need:

• spatula or scraper;
• industrial hair dryer with temperature control;
• drill or drill with interchangeable nozzles;
• grinder or grinder;
• chemical washer;
• a rag to wipe off excess paint;
• respirator, gloves and goggles.

What can be processed?

Which products can be subjected to the paint removal procedure, see below:

• internal and external wooden fittings;
• exterior and interior doors and door frames;
• wooden stair railings;
• window frames and window sills;
• wooden floor boards;
• parquet;
• wooden plinths.

Methods for removing paint and varnish coatings

All efforts to remove the old coating from wooden surfaces come down to four main approaches. How to remove paint from window frames, doors, carved elements than to wash off and erase acrylic paint one of the selected ways, you can find out below:

• Removing old paint from wood surfaces is much easier with this method. The coating, which has already cracked and easily flies off, is scraped off with a spatula or a special metal scraper. Areas that are not so easy to remove manually are finished using power tools. Mechanically, you can easily remove old paint from doors, windows, window sills and other surfaces suitable for processing.
  
• Sandblasting with fine abrasive. A stream of air and fine-grained sand (or soda) crushes and knocks off pieces of the coating from the treated area of ​​\u200b\u200bthe tree. This is not the most used and well-known method. It requires professional and expensive equipment, because such work is performed only by specialists. This is the most expensive, but at the same time fast way removing old paint. With the right grain size of the abrasive and the pressure of the air jet, the tree does not receive any damage.
  
• Thermal way. The paint is heated with an industrial hair dryer and becomes very soft, after which without special work removed with a spatula. If the temperature is too high, the structure of the tree can be damaged. Wood different breeds has its own thermal limits. This effective method removal for almost any, even the oldest paint. Even a person with no experience can remove old paint from a wooden surface with a hairdryer. The molten coating is easily pryed off and removed with a spatula.
  
• Chemical way. A layer of a chemical reagent is applied to the paint, which reacts and dissolves it. Chemical solvents weaken the bond of the paint molecules, and it easily lags behind the wooden surface. Many call this method the most effective. Reagents must be selected for different types of wood individually.
  

How to remove old paint from window frames using this method? With improvised tools, you can quickly remove old paint from a tree and to the very foundation. Remove loose coating with a scraper or spatula. Movements should be strong enough and sharp, but you need to remember that sharp corners spatula can leave marks on the surface of the wood.

Kohler does not require moisturizing or other preparation and is removed immediately. Thus, you can quickly remove old paint from a wooden door and other flat wooden surface. simple tools, which are in almost every pantry or garage.

Further, in those places where the paint holds stronger, an electric tool is used. The door from the old paint, which was applied in more than one layer, is quickly cleaned by grinding. This can also be used to clean wooden windows.

The abrasive paper should not be coarser than number 100, otherwise it will damage the wood.

With smooth movements, the remnants are cleaned from the tree. If the layer is thin enough, then you can not clean the paint with power tools. Sanding machine suitable for flat wooden doors without threaded elements.

Nozzles for a drill in the form of metal brushes should be taken only as a last resort, if there is nothing else at hand and the work needs to be done urgently. Coarse wire will scratch the wood and it is likely that it will need to be primed and sanded before painting, which will entail additional time and cost.

It is better to test any method of removing paint first on a piece of painted wood that is unnecessary or hidden from observation, and then it can be taken for the entire main volume.

Application of sandblasting

Removing paint from a wood surface is easy if you use sandblasting. The jet of air from the compressor mixes with fine solid particles, and then breaks the old paint into dust.

This method will be especially effective if the coating layer is quite thick and you need to remove it quickly enough.

Too coarse abrasive particles will start to break the tree, so often the abrasive is taken smaller. It could be river sand or baking soda. For removing old paint from wood that is not very thick layer, sandblasting is suitable not only because of the speed of work. Removing a thin layer will be beneficial from an economic point of view.

With this method of removal, it is very important to choose correct settings supply of abrasive powder and compressor pressure. Then the coating will fly off instantly, and the tree will remain unharmed.

This method is effective, but it is not economical: processing the entire house can get a tidy sum. A person who has little experience in such work can damage the wood. Therefore, you need to read in advance the reviews about the work of the company that provides this kind of service. Removal of paint in this way occurs gently, without much physical effort.

heat treatment

Old paint is heated with a building hair dryer to such a state until it becomes soft, pliable. Softened paint must be scraped off with a spatula. The operation is repeated until the layer of old paint is completely removed. Temperature, warm-up time will directly depend on the thickness of the layer, as well as the composition of the old coating. This method can be called the fastest of the most effective methods that are available in living conditions. It is not necessary to buy a hair dryer, it can be rented.

Meaning thermal removal not to burn or completely melt the paint. It should lose molecular cohesion, but retain sufficient viscosity for ease of removal.

The painted surface must be heated constantly, evenly, because the color sets quickly and then hardens again. Remove the old paint completely, along with the old primer - while the wood will remain in the same form as it was before the first painting.

Damage to a painted wood surface with a hair dryer is unlikely, and it is almost impossible to provoke a fire. Such cases are extremely rare. This can happen if the wood is impregnated with some kind of combustible compound (for example, gasoline or kerosene is spilled on the floor). Therefore, if you choose how to remove old paint and save the tree, then a hair dryer is perfect for such requests.

Chemical method

If you do not know how and how to clean the window of old paint, then chemical method, according to many builders, the most effective method to get rid of the old coating. The surface is covered with a layer of solvent using a brush, roller or from an aerosol can.

After a while, the coating swells, begins to bubble, wrinkle. This means that she went chemical reaction. Remove the coating according to the instructions on the back of the paint remover. Dissolved paint is easy to clean, it is washed off or removed with a spatula.

Almost all types of coatings lend themselves to chemical solvents. Washers do not cause any harm to wood. A tree cleaned with chemistry can immediately be prepared for painting or varnishing.

Things will go faster if there are cracks on the surface. The washer will quickly fill them, and the reaction will start from both sides at once, which will significantly speed up the whole work. But even for paint without visible defects, chemistry is used successfully.

If the wooden surface is indoors, then good ventilation must be ensured. Be sure to use protective equipment. Chemical paint removers are toxic and can cause irritation, burns, and poisoning.

Some older paints contain lead, which can form toxic volatile compounds at chemical removal paints. It is recommended to use funds personal protection respiratory tract.

Homemade chemical washer

How to remove old paint from window frames? If there are no solvents on hand, then removing paint from wood carried out using a proprietary tool. For this, a chemical paint remover is made from caustic soda. The recipe is below.

You will need:

• water - 4.5 l;
• slaked lime - 0.9 kg;
• soda ash - 1 kg;
• chalk (preferably) - 1 kg.

Soda dissolves in water and is heated to 60 degrees. Lime is gradually poured into the solution, followed by chalk, if any. Ready solution immediately ready to go. According to reviews, it is quite effective, it will wash off the average layer of coating from the tree so that it is completely cleaned. Now you know how to wash off the old coating, how to clean the door and any wooden surface.

Application of different methods (30 photos)

Before painting a wood surface that already has one or more previously applied layers of paint, remove the old coating with the help of improvised means. If you do not know how to remove old paint, use the step-by-step instructions.

First, prepare the wood for painting by sanding and impregnating it with a primer. By choosing the right tools and calculating the forces, you can process up to a meter of the area of ​​the painted surface in 10-20 minutes.

The specificity of wood as a working material is its softness (depending on the species and quality of wood). When preparing a wooden surface for painting or varnishing, determine whether the entire layer of old paint needs to be removed or the product can be treated partially. Consider the following characteristics of the paint being removed:

• thickness- single-layer coating can not be removed. Lacquer (coloring matter) is applied to it easier, holds better, and wood does not lend itself harmful effects once again. At the same time, the creation of very thick layers is fraught with a decrease in strength and density - they are easily destroyed at the slightest mechanical impact.
• invoice(may not match the quality and functional characteristics new cover)
• color- when applying an insufficiently thick and dense layer new paint, the old one will be viewed or the color of the new one will be changed (for example, overlaying blue and red colors will give a purple tint)
• age of applying the old coating- it can flake off on its own. Painting without removing the old layer that is peeling will “make” the treated area bumpy

What is needed to remove old paint from a wooden product?

Inspect the condition of the treated surfaces, the structure and quality of the wood, make sure that the product is suitable for further use. Based on this, select surface treatment methods, dress appropriately (in work, protective clothing) and take special means. Before removing the paint from the wood, prepare the product accordingly (one of the methods that will be discussed later).

To remove the paint and prepare the surface for various operations, use the following tools and a set of materials:

• chemical impregnation for cleaning surfaces from paints and varnishes
• hair dryer used for building purposes
• grinder with a grinding disc or a drill with an abrasive nozzle
• sandpaper, small spatula
• means of protection against toxic substances

How to remove old paint from wood-based products?

To safely and accurately remove old paint from wood, gentle methods and tools are used that cause minimal damage. wooden base or not damaging it at all. Before you remove the paint from the tree, it is affected by:

• chemically
• mechanically
• temperature

Removing paint from wood products with chemicals

With the help of chemical agents, it is fastest and most convenient to remove cracked paint from a wooden base. In a specialized store, you will find a product based on potassium carbonate and lime. There are instructions on the jar correct application substances on the surface, as well as an explanation of how to remove the old paint. Use a soft bristled roller or brush to apply the product to the painted product. After a few minutes, use a small construction spatula to remove the paint from the surface.

The disadvantage of this method is the need to isolate the product from other household items before removing the old paint from the wood. The applied agent is very toxic and easily soaks everything around (it is best to linger on upholstered furniture and dense wallpaper, fabric upholstery). Removal of old paint must be carried out in protective ammunition.

How to remove paint with heat and abrasives?

Before repainting a product, learn how to remove paint from wood using temperature. This method is simpler than the previous one, but more dangerous, as it can cause a fire in the paintwork. The method is based on the fact that when exposed to temperature, the paint begins to decompose and release gas. It penetrates and accumulates under the coating, causing the paint to bubble and completely separate from the wood base.

To thermally to remove old paint from a wooden surface, take a hair dryer or iron, which are used in construction. The hair dryer works like a normal hair dryer, but has very high temperature conditions air heating. In the second case: the foil is applied to the surface, warmed up with an iron from above, and then removed along with a layer of unnecessary paint.

The easiest way to remove old cracked paint is mechanically using:

• grinders or drills with grinding overhead discs
• sandpaper varying degrees hardness (according to the size of the abrasive elements)

This produces a lot of dust, so stock up on protective breathing masks and a gown to safely remove old paint from a wooden product.

Unsafe ways to clean wood products from old paint

It is not recommended to use an open fire (gas burners) to heat the paint layer. This leads to the ignition of the coating material, and then the wood itself. In addition, some types of wood heat treatment allocate special resins, because of which you will not be able to repaint the product later.

Any kind of pre-treatment of the product can lead to backfire if you do not follow the safety rules and work without protection. If the product can be taken out into the open, then it is advisable to do this before removing the old paint from its wooden surfaces. This will help you avoid the extra hassle of cleaning your home, as well as unpleasant odors received after chemical processing wooden thing.

Do I need to remove the old cracked paint from the product at all?

Treating wood before painting further contributes to the effective application of a new paintwork. Inspection of the wood surface will help you determine how to treat and remove old paint, and if it should be done at all. Removal of the coating is necessary if:

• it cracked, swelling appeared
• several layers have already been applied to the surface, from which its coating has become uneven, bumpy
• the previous version was of a different quality / texture or color. This can negatively affect the final result of painting, or the latter will lie unevenly, lag behind, etc.

It is necessary to prepare for the fact that removing paint from the surface is a laborious process that will require a lot of effort and time. If you do not know how to remove paint from wood or do not want to bother with such work, contact qualified craftsmen.

If you started a renovation or just decided to update the interior, then the question of removing old materials will inevitably arise before updating. If we talk about paint, then it is quite easy to remove it from hard metal or concrete. But porous wood is a less obedient material. We will figure out how to remove paint from a wooden surface, and whether it should be done.

Delete or not?

Before painting a tree, it is worth considering: should I put a new layer on top, or should I remove the old one first? The answer is not easy - first you need to evaluate the state of the previous layer:

1. If it is smooth, thin enough and has no visible damage, then you can process it with sandpaper, and this will be enough for painting with the same type of paint.
2. If the layer is covered with cracks, the old paint is swollen in places or a tree is visible through it - it must be removed, the material cleaned and primed before new painting.
3. If you decide to paint the tree with a different type of dye, then the old layer must also be removed.

In any case, it is better to study the materials, how to remove old paint from a wooden surface, and after that make a decision.

Methods for removing old paint

To properly remove paint from a wooden surface, you must select the right way. Which option to give preference to is influenced by many factors that, if possible, should be taken into account as much as possible.

Factors:

• Type of tree.
• Features of its decoration.
• The type of colorant applied to the surface.
• The thickness of the paint.
• How well does the paint adhere to the surface?
• Renovation budget.

Important! Additional experimental samples may be required to accurately determine the type of colorant and determine the number of layers applied.

But first you need to clarify what tools will be required when performing the work.

Tools and materials

In order for the new layer of paint to lay flat and not have to be repainted, it is necessary to remove the old paint from the wooden surface. To do this, you need to prepare well and collect in advance necessary tools. It should be noted that for different ways paint removal will require various tools.

Tools:

• Spatula made of metal, sanding.
• Building hair dryer.
• Drill with grinding attachment.
• Bulgarian with a grinding disc.
• Solvent.
• Protective glasses.
• Overalls.
• Gloves.

The choice of necessary fixtures will depend on the amount of work and the method of removing the old layer.

Removal options

There are three main methods by which you can remove the old layer of paint from wood. It is better not to rush, and study all the methods before starting work.

Ways:

1. Chemical method. It implies the use of special solvents and reagents, for example, special means for removing paint from wood.
2. thermal method. Cleans the painted surface by exposing it to high temperatures.
3. mechanical method. This is an option in which you have to work with your hands. With it, the old layer of paint is mechanically affected.

Let's consider all the methods in more detail.

Chemical method

How and with what can you dissolve and remove old paint? - There are many options. The bottom line is the use of solvents, concentrates, mixtures and reagents that soften and break down the old paint to a state where it is easy to remove.

Fundamental rules:

1. It is most convenient to apply reagents with a paint brush or a finely fluffy roller.
2. After application, wait some time for the reagents to begin to act. Removal of softened paint occurs with the help of scraping or a spatula.
3. Before using this method, the following safety precautions must be taken into account:
   • work only in a well-ventilated place;
   • protect the respiratory system with a respirator;
   • prevent skin contact.

Important! Of the advantages of this method, one can note its speed, ease and lack of physical activity. Of the minuses, it is worth noting that the price of reagents is often not cheap, and their disposal can be difficult. Also, the downside is that most substances are toxic, have a pungent odor, and if used carelessly, they can cause poisoning.

There are options when the tool can be done independently. For example, from potassium carbonate and lime. But homemade substances do a much worse job than their purchased counterparts.

Example:

You can remove the paint chemically using the most common alkali - caustic soda.

This will require:

• gloves;
• overalls;
• scraping;
• brush for applying the solution;
• a container for diluting the solution;
• actually the lye itself.

Application:

1. You must wear protective clothing and protective equipment, then prepare an alkaline solution in a container and apply it with a brush on the old paint.
2. Then you should wait a bit - as soon as the first bubbles appear on the surface, it can be removed with a spatula.
3. Be careful not to damage the tree metal objects. After the procedure, the surface must be degreased.

Important! If the paint layer is very thick - then the best option will make a paste based on caustic soda. For this, preparation water solution alkali and, after dissolving, oatmeal is added to it, and mixed until the liquid becomes pasty. Such a tool can be applied to ingrained paint or hard-to-reach places. You will have to wait a little longer than in the first case, but after a while the paint will definitely come off, and you just have to rinse the surface.

Thermal option

If you have a building hair dryer, then removing old paint from wood is not difficult. The action method is very simple:

1. We connect the building hair dryer.
2. Warm up the painted surface with hot air.
3. Under the influence of the paint softens and bubbles appear on its surface.
4. Without stopping the supply of hot air, the paint begins to be removed with a spatula.

For those who could not find a building hair dryer, there are more a budget option this way. For him, you need ordinary foil and an iron. The foil is leaning against the old layer of paint, and a heated iron is passed over it, through the fabric.

Important! The advantage of this method is its low cost (given that you will not purchase a building hair dryer), easy job with the device.

Of the minuses, a high fire hazard can be noted, so when using this option, be sure to provide for the ability to quickly extinguish the fire.

Also, the disadvantage of the method is the impossibility of using it near electrical appliances, sockets, and when removing coloring matter from plastic.

mechanical method

If it is not possible to remove the old paint by previous methods, there is an option to remove the old coating by physical impact. The process is quite long, but it can be greatly accelerated if you do not act manually, but work with electrical appliances that will help in removing the paint.

Of these electronic assistants, you can use a grinder with a special grinding disc, on which sandpaper is put on.

1. In addition to sandpaper, you can use other abrasive materials.
2. Remember about precautions - protect yourself from dust with a respirator, goggles, overalls and gloves.
3. To reduce the amount of dust, treat the surface with water from a spray bottle.
4. When working with this method, it is important to understand what type of wood you are removing paint from. Some soft rocks may simply not withstand rough handling, and their surface will be severely damaged.
5. It should also be noted that when choosing a coarse-grained sandpaper, the surface can be severely scratched or depressions may appear on it. To avoid this, you need to choose a finer sandpaper and work without applying strong pressure.
6. If scratches or depressions cannot be avoided, the surface can be primed or treated with a special wood putty.
7. If possible, mechanical removal paints from wooden surfaces are best done outdoors.

Important! The advantage of the method is the possibility of its application on a large area.

Carrying out repair and restoration work often requires pre-training. Most often you have to deal with paint, which lies on the surface in several layers. The need to eliminate it is beyond doubt, because a smooth and well-cleaned base is the key to an even and durable coating.

Chemical paint remover

Removal of old paint from wooden surfaces can be carried out in several ways: mechanical, thermal or chemical. The latter has gained particular popularity because it does not require time and effort.

Wood paint remover contains active solvents, various kinds thickeners and thixotropic additives that do not allow the agent to drain from ceiling and vertical surfaces. Some fluids include corrosion inhibitors, leavening agents, and surfactants.

Washes soften and destroy different types paint and varnish coatings, they are able to remove from pentaphthalic, oil, alkyd, glyphthalic, petroleum polymer, melamine alkyd, polyurethane and powder-based putties. It is thanks to this versatility that the wash has become widespread.

Features of use

The wash is applied in a uniform layer so that its thickness is not less than the thickness of the washable coating. To reduce time and increase efficiency, the area to be cleaned is covered with plastic wrap.

Note!
Apply the wash with a stiff brush in a thick, even layer.
The tool is led in one direction, while trying not to re-run over the treated area.

After the time specified by the manufacturer, the remnants of the product, together with the paint, are removed with a chisel, spatula or high-pressure water.

After complete cleaning, the tree is treated with a solution of vinegar, prepared in a ratio of 100 ml of vinegar for every 0.5 l of water. Wipe the surface with a flannel cloth and leave to dry completely as far as possible from sun rays. Otherwise, there is a high probability that the wood will crack.

Note!
Washing mixtures have a rather unpleasant, pungent odor, so all work is recommended to be carried out in a well-ventilated area.

Blend selection

Homemade washes

You can make your own wood paint remover.

1. In a convenient container, combine the solution ammonia(10%), a liter of water and 2.5 kg of chalk. The resulting viscous mass is applied to the surface to be cleaned. After 4 hours, paint residues peel off and can be easily removed.
2. If you delete the old paintwork to be from a plank floor, experts recommend using soda ash. The floor area is thoroughly moistened with water, covered with a layer of soda ash, covered with wet burlap. After 24 hours, the swollen paint is removed with a spatula.
3. No less effective is a mixture prepared from quicklime (1.2 kg), potassium carbonate (0.4 kg) and water.. A homogeneous thick mixture is spread over the surface and left for at least 12 hours.

Advice!
If you do not like multicomponent compositions, pay attention to using liquid glass.
The agent is applied to the plane and left until a silicate film is formed, which will peel off along with the old coating.
The procedure is repeated several times until the desired result is obtained.

How to remove paint from a wooden surface? In the process of repairing a house or apartment, there is almost always a need to update and give noble-looking important components of the interior: entrance and interior doors.

Of course, it is much easier to install popular plastic counterparts and subsequently admire the elegant look that the room will immediately “put on”.

But it's much better to live surrounded by natural materials that need only be updated, restored and made modern by ordinary painting.

Is it necessary to remove old paint?

According to the state of the old layer of paint, you should decide: apply fresh paint over it or still make preliminary cleaning from the old decor. Main criteria for acceptance right decision will become:

• The age of the previous painting, which, under the influence of time, can begin to peel off on its own. If a new layer is applied to the peeling surface from above, then the painted area will have a bumpy and sloppy appearance.
• Thickness. A single layer of the previous coating can not be removed. The coloring matter is superimposed on it much better and lasts longer. In addition, wood is not threatened by another impact. When multi-layered, the paint layer is characterized by low strength and density and is destroyed with a slight mechanical impact.
• Color. When applying a thin and loose layer of paint, color will show through old surface, or there will be a mixing of new and old paints. For example, red over blue will result in a purple tint.
• Invoice that may not match quality characteristics the previous layer. So how do you remove old paint from a wood surface?

Preparatory stage

In the absence of cracks, blisters and damage on the working surface, pre-paint treatment will be sufficient. Remove a thick layer of paint or accumulated over many years. a large number of layers. on concrete and metal products, characterized by a solid surface, it is much easier to get rid of the old coating than on wood - soft material easily damaged. How to remove old paint from a wooden surface at home?

Before removing the previous coating, first of all, you should examine the condition, structure and quality of the product planned for painting and make sure that it is possible to continue using it.

Getting rid of old paint: effective methods

Let's figure out how to remove old paint from a wooden surface at home.

Removing the old layer is a rather laborious process that requires a lot of time and effort. Therefore, sometimes referring to professional craftsmen better than independent action. There are several gentle ways to carefully and safe removal an old coat of paint that causes minimal damage to the wood base:

• chemical, involving the use of various reagents;
• thermal, using high temperatures;
• mechanical, in which the impact on work surface performed using auxiliary tools.

When choosing methods for removing old coatings, personal safety should be observed and protective equipment must be used.

chemical method

How and how to remove old paint from a wooden surface in the fastest, most dust-free and no application required special efforts in a chemical way?

Getting rid of the previously applied layer is carried out by processing the product with special chemical solutions impregnating the paint and foaming it from the inside. The application of such effective substances is required to be carried out using an airbrush, a roller with a fine pile or a brush. Next, you should wait 20-25 minutes to allow the substance to fully show its destructive abilities. As a result, the old layer will be removed without much difficulty.

To help, you can take mechanical tools (for example, a spatula).

It is problematic to use chemicals when removing old paint on the ceiling, but manufacturers have found a way out and produce such products in the form of jelly. Even if they are applied with a brush, they do not flow down.

By financial standards, the chemical method is very expensive: a unit of the drug High Quality in monetary terms, it is equal to the price of the paint itself. In addition, the used material needs special disposal. The disadvantage is the pungent smell of drugs, as well as their release of toxic fumes. Therefore, in order to avoid burns and poisoning, work should be carried out in a respirator, protective gloves and goggles. Before starting the process, the room must be well ventilated. And what is the easiest way to remove old paint from a wooden surface?

Using hot air

The invention of the building hair dryer led to the emergence of thermal removal of the old paint layer. Are you wondering how to remove old paint from a wooden surface with a hair dryer? The device is able to heat the surface up to 600 ° C. Under the influence of high temperatures, the paint foams and is easily removed with a chisel, scraper or spatula.

The building hair dryer is not recommended for use in rooms with plastic windows and open wiring, because at high temperature the latter can ignite easily. In the absence of a building hair dryer, you can use food foil: attach it to the surface, warm it up with an iron (an old one that is not a pity). The “ironing” method warms up the surface, so you can safely get rid of the old layer of paint.

It is not recommended to act on the working area of ​​the product with open fire to remove old paint ( gas burners) due to the risk of possible fire. In addition, this can cause drying and violation of the wood structure, which negatively affects the strength of the product and its service life. Certain types of wood during heat treatment are capable of releasing flammable resins, which also form a specific film on the product. The latter significantly reduces adhesion (adhesion of surfaces), and may even prevent the application of a new layer of coloring matter to the product.

Efficient mechanical method

Let's learn more ways to remove old paint from a wooden surface at home. The mechanical method is quite effective, which is scraping off old paint with the help of improvised tools: a knife, spatula or grinder. On a small and uneven surface, it can be scraped off with sharp tools.

How to remove old paint from wood large areas? In this case, it is effective to use a power tool that significantly speeds up the workflow: grinders or drills with special wheels on which sandpaper or any other material with an abrasive is put on.

An emery-petal disk can easily cope with one layer of old paint, if there are several layers, the use of brush brushes is effective as nozzles.

Features of working with wood
