How to remove old paint from a wooden surface at home? How to remove paint from a wooden surface

Most finishing craftsmen agree that before repainting wooden items and facades, the old decorative layer must be completely removed. But how to remove this “makeup”? And is it possible to do without such a labor-intensive and tedious procedure?

If the paint was applied once and adheres well, it does not need to be removed. It is enough to go over with fine-grained sandpaper to remove noticeable irregularities. But in the case when painting was done many times, all decorative layers will have to be removed, otherwise the new paint will fall off along with the old one.

Removal methods old paint several, and we will look at the main ones.

Mechanical method

The simplest and affordable way paint removal - mechanical. This will require several sheets of sandpaper and quite a lot of patience. First, the surface is treated with large, rough sandpaper, removing the decorative layer. And then gradually bring the surface to smoothness, cleaning with increasingly fine abrasive.

Working with sandpaper, you can wrap it around a small wooden block, which is comfortable to hold in your hand. This will make your work much easier

Manually removing old paint is an extremely time-consuming and tedious process. It can be easily speeded up by using a grinder or drill with appropriate attachments. A flap sanding disc can easily handle a couple of layers of old paint. But in particularly advanced cases, you will need a brush with metal bristles.

The instrumental method of removing paint has two significant disadvantages. The first is the formation of deep scratches that have to be sanded or filled with putty. The second is the dust generated during work. It is very important to work in a respirator and safety glasses so as not to harm your health.

Deserves special mention sandblasting method. For this you need special machine, which delivers a stream of air or water mixed with fine sand. The grains of sand effectively and at the same time quite gently remove the old paint layer.

The disadvantage of this method is obvious - the need to use special equipment and attracting qualified specialists. But if you need to clean large surfaces (for example, facades) of old paint, the sandblasting method will probably be the most profitable, as it will save a lot of precious time.

Thermal method

When removing paints that form a dense thick film on the surface, heating works effectively. For example, you can blow the surface construction hairdryer, and then scrape off the melted paint with a knife or spatula.

If you don’t have a hair dryer at hand, the way out is... an ordinary one. household iron. The wooden surface is covered with a sheet of aluminum foil and ironed until the paint begins to peel off. Of course, you can’t clean a large wall like that, but for doors, window frames or furniture, this method is quite acceptable.

But to influence the paint with a blowtorch or gas burner, as some experts advise, it’s probably not worth it. First of all, for reasons fire safety . But there is another, quite significant reason. At best, an open fire will dry out the wood, which can lead to cracking. At worst, it will simply burn, making further coloring impossible. However, burning wood in itself is decorative processing

, which we wrote about in the article “Burn it with fire.”

When heated, some types of wood release resin, which settles on the surface in the form of a film, significantly complicating further painting.

Chemical method

The described method is quite effective, but it should be noted that caustic soda is a very aggressive chemical reagent. When working with it, you must use protective gloves and a respirator. If paint removal occurs inside the house, it is very important to ventilate the area well immediately after completion. If the composition gets on the skin, it must be washed off with plenty of water.

Also, to remove paint, use gasoline, a mixture of turpentine and grated laundry soap and a number of other homemade recipes. And for those who don’t want to become an “alchemist”, many special flushes have been developed j. There are products for oil coatings, nitro paints, enamels, etc. We emphasize that the vast majority of them are flammable and toxic, and therefore require the strictest adherence to safety measures. Conscientious manufacturers attach to their product detailed instructions, where all are indicated necessary measures protection.

High quality, effective means paint removal can cost as much as the paint itself, and sometimes more

To wrap up the topic, let’s add that when starting to remove paint, it will be useful to stock up on wood bleach. The point is that under the old decorative layer Often unpleasant surprises are discovered - darkening from rot and fungus. Theoretically, you can lighten the surface with a chlorine solution, but it would be wiser not to “chemically” at home, but to purchase a ready-made preparation intended for these purposes. Almost all large companies that produce paints, antiseptics and fire retardants for wood offer such products.

The renewed surface is washed, dried, primed and painted again. New decorative composition must be the same type as the previous one, although there are exceptions to this rule. For example, on oil paint Can be applied both oil and acrylic.

Remove old paint from wooden surface you can do it yourself at home. To do this, you will need to use proven folk remedies or special formulations. Typically, unnecessary coating is removed in three ways: mechanical, thermal and chemical. When choosing a product, you need to take into account that wood is quite soft material. Therefore, it is easy to damage it using rough mechanical force or aggressive chemicals.

When should you remove old paint?

In some cases, it is not necessary to remove a layer of old paint. The new coating can be applied directly to the old one. But sometimes you still have to remove previously applied paint.

It depends on the condition of the old coating. If it peels, cracks and peels, you must definitely get rid of it. Otherwise, the new paint will lie unevenly and bulge.

In addition, it is very important to take into account the color of the old and new paints. If the old coating is bright, and the new one has pastel shade, there is a risk that it will not be possible to paint over the original color. If both colors are quite bright, the shades may mix. Then the result will be unexpected. For example, if you apply a layer of red paint over yellow paint, the finish will be orange.

You should also pay attention to the number of layers of old paint. If there are a lot of them, the new coating will not adhere well and will soon crack. If only one layer was previously applied, you can paint the surface without removing it. This will make the new paint go on even smoother.

It is worth comparing the compositions of old and new paints. If they are very different, then you need to remove the previous coating, since in this case it is unlikely to provide good adhesion.

How to remove paint?

If, after inspecting the old coating, a decision was made to remove it, you must choose the appropriate method.

There are several proven methods for removing old house paint: mechanical, thermal and chemical.

If the surface is large and flat, then the fastest way to remove the previous coating is by mechanical force. For cleansing relief surfaces recommend using high temperatures or chemicals.

Mechanical method

Take off paintwork from the floor, wall or level table, the easiest way is to use electric tools.

This could be a grinder or a drill with abrasive wheels. Moreover, the softer the wood being cleaned, the less abrasiveness should be chosen. To remove a thick layer of paint, you can use a brush.

Do not press too hard on the tool during the cleaning process, otherwise you may damage the product. At the very beginning, touching the surface should be barely perceptible. The pressure can be increased as needed.

Removing paint with an angle grinder

With this method of cleaning, it is very important to protect the mucous membranes and respiratory organs, since during the process a cloud of dust rises from the paintwork being removed. Therefore, it is imperative to wear safety glasses, a respirator, and clothing that covers exposed areas of the body as much as possible.

If you don’t have a suitable power tool at hand, you can use a scraper, spatula or knife. It is undesirable to use sharp objects, as soft wood can easily leave scratches. This method is usually used if the paint has already cracked and started to come off.

The tool should be positioned at an angle to the surface to be cleaned. You need to move slowly and carefully, gradually increasing the pressure.

Removing old paint with a spatula

After removing the base layer, some uncleaned areas may remain on the tree. You can clean them with fine-grained sandpaper. You should not use coarse sandpaper, as there is a risk of damaging the surface.

If after mechanical cleaning If there are still scratches on the wood, it is necessary to smooth them out with putty, and then treat the surface with a primer.

Heat treatment

Another way to remove old coating is to use high temperatures.

When heated, the paint breaks down and begins to crack. After this, it can be quickly removed with a spatula or scraper.

If the area to be cleaned is quite large (walls, floors, doors), the power of a conventional hair dryer will not be enough. In this case, you will need to use a hair dryer. It is able to very quickly heat the coating to the desired temperature.

How to remove paint with a hair dryer

But there are a number of limitations to using such a powerful hair dryer. There shouldn't be any in the room plastic windows and outdoor electrical wires. Otherwise, a fire may occur.

Small areas can be cleaned using foil and an iron. To do this you need:

place a piece of food foil on the old coating;
heat the iron as much as possible;
iron the surface through the foil;
When the paint starts to peel, it will need to be scraped off.

For this procedure, it is worth taking an old iron, as traces of foil may remain on the sole..

To remove old paint from a wooden surface, under no circumstances should you use open flame sources. After all, wood with a paint coating is a flammable material. Even if the surface does not catch fire, the wood will be damaged, since it dries out under the influence of fire.

Chemicals

If previous methods did not help get rid of the old coating, you can use chemicals. These can be either ready-made formulations or improvised means.

In any case, you will have to use personal protective equipment, since the substances used can damage the skin if they come into contact with the skin. In addition, the fumes of some of them are toxic. Therefore, before starting work, you must wear construction glasses, thick gloves and a respirator.

To remove paint, use this proven folk remedy, like soda. Regular food will not cope with this task. Therefore, you will have to take calcined or even caustic.

How to use soda ash:

mix the powder with lime in a ratio of 1:3;
apply the resulting composition to the coating;
wait 15–20 minutes until the paint begins to swell;
then clean it off with a stiff bristle brush or spatula.

You can also use caustic soda. But this substance is quite aggressive, so it should be used carefully.

Procedure steps:

combine caustic soda and oatmeal in equal proportions;
dilute the mixture with water to a paste;
spread the surface with the prepared mixture;
leave for 10 minutes;
After the specified time has passed, remove the mixture with a spatula along with the old paint.

Finally, the surface should be degreased using a special product. You can simply wipe it with a slightly damp cloth. But it is important to remember that wood begins to rot from excess moisture.

These products can handle almost any paint: both acrylic and oil.

You can also use solvents such as acetone or white spirit. But this will only help if the coating is thin enough. To get rid of paint for sure, you can purchase special means in the shop household chemicals. They can be in the form of aerosols, liquids, foams, etc. Such products act quickly and effectively, destroying the paint composition. After application, just wait 10–20 minutes and remove the peeled coating with a spatula.

To remove old paint, you should choose products that are effective but safe for the human body and the wooden surface. After stripping the coating, you need to treat the wood with primer. Only after this can you apply new paint.

And a little about secrets...

The story of one of our readers, Irina Volodina:

I was especially distressed by my eyes, which were surrounded by large wrinkles, plus dark circles and puffiness. How to completely remove wrinkles and bags under the eyes? How to deal with swelling and redness?But nothing ages or rejuvenates a person more than his eyes.

But how to rejuvenate them? Plastic surgery? I found out - no less than 5 thousand dollars. Hardware procedures - photorejuvenation, gas-liquid peeling, radiolifting, laser facelifting? A little more affordable - the course costs 1.5-2 thousand dollars. And when will you find time for all this? And it's still expensive. Especially now. That's why I chose a different method for myself...

Depending on the chosen cleaning method, you will need:

metal spatula, chisel or special scraper;
hair dryer for construction work;
electric drill with attachment;
grinder with a disc for cleaning and grinding;
paint remover;
personal protective equipment in the form of gloves and goggles.

Depending on the area of the surface being processed, you will definitely need some of the listed tools and materials.

Basic removal methods

Before removing old paint from wood, you need to familiarize yourself with cleaning the surface and select best option for your wood product.

Today the most common are:

chemical method using special reagents;
thermal method using high temperatures;
mechanical using mechanical action on the surface.

Chemical removal method

For this purpose, special solutions are used that contain chemical reagents to destroy the paint layer on the surface.

The reagents are applied to the product to be treated using a regular brush or fine-pile roller. After this, you need to wait the set time for the chemical to do its job and finish painting with a spatula, without applying any force.

This cleaning option is considered the fastest and does not require physical activity However, chemicals have pungent odors and toxic substances are released when handled. Before using them, it is necessary to ventilate the room and use a respirator to protect the respiratory tract. It is also necessary to use protective gloves, as contact of this substance with the skin can cause chemical burns. It is worth noting that they are quite expensive and the waste material requires special disposal.

You can prepare a composition for destroying old paint and varnish yourself. For this, a mixture of lime and potassium carbonate is used, however, this product is much less effective.

Thermal removal method

Everyone has long known about old coatings using a conventional hair dryer, since this option is the cheapest and very effective.

It is enough to simply heat the painted surface to the desired state, after which the paint can be easily removed with a regular scraper, spatula or chisel. If you don’t have a hair dryer and don’t have the necessary finances to buy a new one, you can use regular metal foil. Place the foil against the surface and heat it with an iron, then the old layer.

Before removing old paint from wood using a thermal method, it is worth considering that the treated coating can ignite if it is overheated, so take care of the possibility of extinguishing in advance. It is also not recommended to use a hair dryer in or plastic products, since the temperature can damage them.

Mechanical cleaning method

If it is not possible to use thermal or chemical methods to remove the old coating, then you can use mechanical cleaning. This is effective when working on large areas, because due to the use of various electrical devices the process is significantly accelerated. Most often, a grinder with a special circle is used, on which sandpaper or any other similar material with abrasive.

When using a grinder or electric drill, paint is removed dry, which is accompanied by a large amount of dust. When working, be sure to use protective gloves, goggles and a respirator. Before removing paint from wood mechanically, it is necessary to take into account the type of wood, since the use of abrasive materials can cause damage to the surface being treated. Not making the right choice sandpaper.

If the sandpaper has coarse grain, then when processing with great pressure on the surface, depressions may appear in the wood. If this happens, then change it sandpaper to a smaller one or do not apply much effort when processing. In case of depressions, the surface must be puttied and treated with primer before painting.

Some craftsmen use a thermal method to remove old coating by exposing the treated area of the product to open fire. Using this method is highly discouraged due to the increased risk of possible fire.

In addition, when processing products from various types of wood using this method, the material dries out and its internal structure is damaged, which significantly reduces the strength of the product and its service life.

Some such processing may release resins that are easily flammable or create a film on the product. This film will significantly reduce adhesion, and may even prevent you from applying a new layer to the surface.

When choosing methods for removing old coating, the main thing is to follow the rules of personal safety, use protective equipment and follow safety precautions when working with electrical appliances.

Faded and cracked paint on wooden frame, doors, log house and any other cleaned wooden surface that is present in the house carries a certain charm of antiquity and comfort. But time and weather conditions have not been 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. This article is about how to remove old paint from wood.

Before you pick up a hair dryer, a brush with a chemical remover and read about how to remove old paint from a wooden surface, you need to find out about the type of wood with which you will be working. Some types of wood require more care than others. For a good result on any tree, you must follow the technology - correctly use products for removing decorative coatings.

It would be a good idea to find out about the age of the wood, its operating conditions, climatic conditions, as well as other factors that have or previously had an impact on painted wood.

Wood can last for decades only with proper, constant care. In some cases, wood exposed from the old paint layer will require treatment protective equipment, otherwise the new coating will not last very long.

Preparing tools

Prepare your tools in advance. To remove you will need:

spatula or scraper;
industrial hair dryer with temperature control;
drill or drill with replaceable attachments;
grinder or grinder;
chemical remover;
a rag to wipe off excess paint;
respirator, gloves and safety glasses.

What can be processed?

See below for which products can be subjected to the paint removal procedure:

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 baseboards.

Paint removal methods

All efforts to remove 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 methods, you can find out below:

Removing old paint from wood surfaces is much easier with this method. The coating, which is already cracked and easily flies off, is scraped off with a spatula or a special metal scraper. Areas that are not easily removed by hand are finished using power tools. Mechanically, you can easily remove old paint from doors, windows, window sills and other surfaces suitable for treatment.
Sandblasting with fine abrasive. A stream of air and fine-grained sand (or soda) crushes and knocks down pieces of coating from the treated area of the tree. This is not the most used and known method. It requires professional and expensive equipment, so this work is performed only by specialists. This is the most expensive, but at the same time quick way removing old paint. With the correct abrasive grain size and air pressure, the wood does not suffer any damage.
Thermal method. The paint is heated with an industrial hair dryer and becomes very soft, after which, without special labor removed with a spatula. If it's too much heat, then the structure of the tree can be damaged. Wood of different species has its own limits of thermal impact. This effective method removal for almost any, even the oldest paint. Even a person without experience can remove old paint from a wooden surface with a hairdryer. The melted coating is easily pryed off and removed with a spatula.
Chemical method. A layer of a chemical reagent is applied to the paint, which reacts and dissolves it. Chemical solvents weaken the bond of paint molecules, and it easily lags behind the wooden surface. Many people call this method the most effective. Reagents must be selected individually for different types of wood.

How to remove old paint from window frames using this method? Using available tools, you can remove old paint from wood quickly and down to the very base. Remove loose coating with a scraper or spatula. The movements should be quite strong and sharp, but you must remember that the sharp corners of the spatula can leave marks on the surface of the wood.

The color does not require moistening or other preparation and is removed immediately. This way you can quickly remove old paint from a wooden door or other flat wooden surface. simple tools, which are found in almost every closet or garage.

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

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

Using smooth movements, the residue is cleaned from the tree. If the layer is thin enough, then you don’t have to clean the paint with power tools. Grinder suitable for flat wooden doors without threaded elements.

Drill attachments in the form of metal brushes should be used only as a last resort, if there is nothing else at hand and the work needs to be done urgently. Rough wire will scratch the wood and there is a possibility that it will need to be primed and sanded before painting, which will entail additional time and money costs.

It is better to first test any method of removing paint on an unnecessary or hidden piece of painted wood, and then you can take on the entire main volume.

Application of sandblasting

Removing paint from a wooden surface is easy if you use sandblasting. The air stream from the compressor mixes with small 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.

Abrasive particles that are too coarse will begin to break up the wood, so often the abrasive is taken smaller. It could be river sand or baking soda. For removing old paint from wood, which does not have a very thick layer, sandblasting is suitable not only because of the speed of work. Removing a thin layer will be beneficial with economic point vision.

With this removal method, it is very important to select the correct settings for the 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: treating the entire house can cost a pretty penny. A person who has little experience in such work can damage the wood. Therefore, you need to read the reviews in advance about the work of the company that provides this type of service. Removing paint using this method occurs carefully, without much physical effort.

Heat treatment

The old paint is heated with a hair dryer until it becomes soft and pliable. The softened paint must be cleaned off with a spatula. The operation is repeated until the old paint layer is completely removed. The temperature and heating 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. There is no need to buy a hairdryer; you can rent one.

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 quickly sets and then hardens again. Remove the old paint completely, along with the old primer - the wood will remain in the same form as it was before the first painting.

A hairdryer is unlikely to damage a painted wooden surface, and it is almost impossible to cause a fire. Such cases are extremely rare. This can happen if the wood is saturated with some kind of flammable compound (for example, gasoline or kerosene was spilled on the floor). Therefore, if you choose how to remove old paint and preserve wood, then a hair dryer is perfect for such requests.

Chemical method

If you don’t know what and how to clean a window from old paint, then the chemical method, according to many builders, is 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 aerosol can.

After some time, the coating swells, begins to bubble, and wrinkle. This means I 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 coating are amenable to chemical solvents. Removers do not cause any harm to wood. Chemically cleaned wood can be immediately 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 begin on both sides at once, which will significantly speed up all the work. But even for paint without visible defects, chemicals are used successfully.

If the wooden surface is located 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 old paints contain lead, which can form toxic volatile compounds when used. chemical removal paints. It is recommended to use personal respiratory protection equipment.

Homemade chemical remover

How to remove old paint from window frames? If there are no solvents at hand, then removing paint from wood carried out using a self-made product. To do 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 is dissolved in water and heated to 60 degrees. Lime is gradually poured into the solution, followed by chalk, if available. The finished solution is immediately ready for use. According to reviews, it is quite effective; it will wash away a medium-thick layer of coating from wood so that it is completely clean. Now you know how to wash off the old coating, how to clean the door and any wooden surface.

How to properly remove old paint (2 videos)

Application of different methods (30 photos)

One of the most effective ways to remove old paint from wood is to use a chemical stripper. The cleaning agent reacts with the paint material, causing the coating to soften and foam. The main advantage of chemical removers over other methods (mechanical, thermal) is that their action is more gentle on wood.

Types of washes

All types of washes are divided into two large groups: universal and specialized. Universal compositions are designed to remove any paints and varnishes from wooden surfaces. They are capable of dissolving paints and varnishes(LKM) both water-based and containing organic solvents.

The purpose of specialized removers is to soften only certain types of paints. For example, there are separate remover compositions for removing textured, oil-based and other types of paintwork materials. Specialized removers are considered more effective, since their development takes into account the characteristics of specific types of dyes. At the same time, specialized formulations are more expensive.

Removers are produced in the form of liquids, jelly and dry substances for further dissolution. When choosing a cleaning composition, it is necessary to proceed from the circumstances: for example, a jelly-like paste adheres well to wood, and therefore will not drain from vertical surfaces.

But liquid wash compositions - the best choice, if you want to clean a surface that has small parts or fine threads. If we are talking about expensive furniture (especially those covered with veneer), you need to choose a liquid that can be removed with white spirit, since if this is not done in time, the wood fibers of the product will swell.

Before purchasing a remover, it is recommended to carefully read the instructions (usually they are written directly on the packaging) or consult with a sales consultant. It should also be taken into account that not every preparation is suitable for working with wood. Therefore, it is important that the cleaning composition is intended specifically (or including) for wooden products.

Instructions for using the remover

The work consists of two stages: preparation and application of the wash.

Preparatory activities

Before you begin removing paint, you need to prepare the surface. To do this you will need to do the following:

We remove dust and dirt from the surface.
Closing plastic film floor and all non-wooden parts on the product.
We carefully wipe the wood - it should become dry.

Applying the remover composition

The work is performed in the following order:

Wet the brush in the preparation and treat the surface with it.
We wait for 30-45 minutes so that the composition saturates the wood well.
We try to remove paint from any area using a scraper. If it works, we continue to clean the surface mechanically.
If the coating does not work, stop trying and apply another layer of remover.
Usually two soakings are enough. Separate the paintwork using suitable tool: scraper - for flat surfaces, scraper - for shaped profiles, wire wool - for carved parts. In the case of carved oak, we use a nylon sponge with an abrasive material, since metal leaves stains on this type of wood.
We separate the paint along the grain, but not across it. To neutralize the remover, we wet the wood with white spirit.
We complete the removal of the coating by wiping the surface with a damp cloth.
We wash the wood with warm soap solution. This way we degrease the material.
Let the product dry, after which you can apply primer and paint.

Example of a wash composition

As an example, let’s look at the capabilities of a popular paint remover from wood – “Docker Wood” – that is popular among consumers. The composition is fast-acting: the effect occurs within 5-15 minutes. Maybe high-quality removal many types of coatings, including water-dispersion and oil-based. For example, Docker Wood works well with pentaphthalic enamels with markings such as 115,133 and 126. The product contains special components that protect the wood from damage during paint removal.

Advantages of Docker Wood:

versatility in relation to paint and varnish coatings;
economical consumption (approximately 200 grams per square meter);
gentle effect on wood;
deep penetration that has great importance when removing a multi-layer coating;
performance;
no toxicity;
fire safety;
the drug retains its quality even after repeated defrosting;
complete absence of odor;
The wash works even at sub-zero temperatures (down to -7 degrees Celsius).

Note! Before use, as well as in case of defrosting, the drug must be stirred well.

Methods of application

Before applying the composition, prepare the surface. We remove dirt and dust using water and cleaning products. The washing material can be applied manually (brush, roller) or by immersion.

If selected manual method, apply the wash using a brush or other tool in a layer of 1-2 millimeters. After some time (5-15 minutes), remove the peeling paint with a stream of water or a spatula. We apply another (control) layer of remover and, after waiting a while, clean the surface again. If the paint does not lend itself, you can apply more than two layers of the stripping composition, but it should be remembered that the maximum contact time of the wood with the preparation is 2 hours.

Note! Wood should not be left to dry unless the stripper has been removed.

The coating can also be removed by immersion. To do this, pour Docker Wood into a suitable sized container and immerse it there. wooden part. After 5-15 minutes, remove the paint layer in the same way as described above. In case of dipping total time The presence of wood in the wash should not exceed half an hour.

Safety precautions

When working with Docker Wood, extra precautions should be taken:

Do not forget to use protective equipment against acid damage (safety glasses, apron, respirator, gloves).
If the drug gets on the skin or eyes, immediately rinse the affected surface with plenty of water and, if necessary, consult a doctor.

Storage Features

Docker Wood can be stored in its entire packaging at temperatures ranging from 0 to 30 degrees Celsius. The drug retains its quality for a year from the date of manufacture. If the package is opened, the remover must be used within 24 hours.

Alternative methods

If there is no proprietary wash composition, other preparations can be used. Below are some instructions for using different .

You can use either regular caustic soda or a solution that, in addition to soda, includes oatmeal and water. When using this chemical, do not forget about safety precautions (safety glasses, gloves).

Instructions for using caustic soda:

We dilute baking soda in a container with water.
Apply the solution wide brush. The remover must be distributed sequentially, without gaps on the surface.
We wait until the soda saturates the wood. After a while, the soda will begin to corrode the paint, and the coating will become covered with bubbles.
Remove the paint layer with a metal spatula. If there are pits in the surface, you can use a chisel, small spatula or a piece of sandpaper.
We wash the wood first with a soap solution and then with a stream of warm water.
Dry the material well before priming or painting it.

If the paint layer is thick or there are hard to reach places, it is more effective to use a thick composition. You can achieve thickness by mixing baking soda with oatmeal in water. The waiting time after applying the solution to wood is approximately 1-2 hours.

Bleach can be used both as a stand-alone paint remover and as an addition to remover. In the latter case, bleach acts as a bleach. The fact is that after removing the paint, rotting or fungal damage will be revealed. In such cases, stains are inevitable, which bleach will help to whiten.

The paint is removed as follows:

We dilute bleach in a container with water.
Apply the chemical to the surface using a hard brush or steel wool.
As the bleach evaporates, the wood will gradually dry out.

Note! You can work with bleach only in conditions of good air circulation and using personal protective equipment.

Other cleaning methods

When choosing a paint removal method, you should take into account the principle of “remove like with like”:

Paints on water based can be deleted warm water, a stiff brush and rags.
Oil-based coatings (paints based on fir or linseed oil) can be softened with turpentine. However, if the layer is thick, this will not be so easy. Oil-based paints are the most difficult to remove.
Enamel paints begin to peel off after treating the surface with acetone or another solvent.

Precautionary measures

As mentioned above, when working with chemicals it is necessary to follow safety regulations. These rules include not only the use of a respirator, safety glasses and gloves, but also other recommendations, including:

Good lighting in the work area helps prevent injury.
To process large items, you need to use a durable table or other flat surface.
