How to remove and renew old paint. How to remove old paint from a wooden surface at home

During the repair, each of us faced the problem of removing old paint. This is especially a time-consuming process when it comes to removing paint from wooden surfaces, because. wood has the ability to absorb any liquids, including paint. The process of removing paint from wood is called decamping. What are the methods of decamping?

mechanical way

Of course, you can make an effort and clean the wooden surface by scraping old paint with a spatula or a wire brush. If it is a flat surface, then this process will not cause any special difficulties. And if necessary, remove the paintwork from decorative surfaces: carved furniture, twisted architraves, etc., this will be a very laborious process. A bunch of hard-to-reach places, recesses will not allow you to clean the surface qualitatively. In addition, a sharp spatula can damage the tree or injure yourself.

Heat exposure

Another method that is often used at home to remove paint from wood is to heat the surface with a household hair dryer and remove the swollen paint with a spatula. The method may not be bad for cases where you need to clean a small area of old paint, and if it's the whole walls in the house or the floor. Can you imagine how much effort it will take?

homemade solution

You can use a solution of caustic soda. This method is suitable for all surfaces, but requires special care, because. this solution is a chemical composition. Therefore, it is necessary to protect the face and hands from contact with the skin. After application, the paint begins to bubble and is easily removed with a spatula. Do not forget to wipe the surface cleaned of old paint with a degreasing compound or water.

Chemicals

The simplest and quality way removing a particularly multi-layer paint is to buy a chemical agent for this purpose in the store, choosing it for a specific type of paint applied to a wooden surface. Chemicals are acids and alkalis, the use of which requires special care and the use of protective equipment for the skin (rubber gloves), the respiratory tract (they have a sharp specific smell) and the eyes (goggles). For domestic purposes, solvents containing acetone are usually used.

V Lately effective and universal washes appeared, the safest in their application. An example of such a tool is Docker S5, a tool from Docker Chemical that allows you to remove paintwork without damaging and blackening the surface.

Wood paint remover DOCKER Wood fast action (5-12 min.). Effectively removes paint coatings (water-dispersion paints, oil paints, enamels PF-115, PF-133, PF-266, GF-021, etc.) from wooden surfaces. Deep penetration wash. gel solution. A special additive allows you to save the structure of the tree without damaging the surface of the wood. Without smell.

At repair work often there are difficulties with the restoration of battered species wooden windows and doors, as well as furniture. Of course, it is easier to acquire everything new than to restore the old. But it's hard. Yes, and part with familiar objects sometimes it's a pity.

Updating surfaces by painting them is easy. Much more time and effort will be spent on removing the cracked paint and getting ready to apply a new one. The question immediately arises - how to remove paint from wooden surface most efficient?

Effective cleaning methods

There are several ways to remove paint. Each of them is good in its own way, but also has some drawbacks. You can choose best option, based individual features surfaces.

mechanical way

If the coverage area is small, it is quite suitable. handmade using ordinary sandpaper.

Pre-treatment is done with a coarse-grained sandpaper, then the surface is brought to fine-grained readiness.
A wooden block will facilitate the process, around which a piece of skin is wrapped. This is the simplest and available remedy for removing paint from wood. Disadvantages - too quickly clogged skin, which will often have to be changed and the complexity of the action.

To speed up the cleaning process, a grinder with a wire brush attachment is useful. You can use an electric drill by attaching a similar addition with a hard metal bristle or a nozzle with a sandpaper to it.
Widths, a hand planer, a chisel, a rasp and a file will help to free the surface. All this can be successfully combined, adjusting to the features of the relief.

For industrial purposes or in the case of large volumes, sandblasting is effective.

From the apparatus high pressure a jet of air or water mixed with sand is supplied.
Sand grains, hitting at high speed, remove the old layer. Moreover, the device works equally well both on wood and on metal.
The downside is the high price of the device and the need for skills in working with it.

Note!
The work will certainly be complicated by dust and particles of the removed layer.
Therefore, it is desirable to carry out the processing, having previously equipped.
Use a respirator to protect the respiratory tract, special goggles for the eyes.
Put on gloves on your hands.

Heat treatment

Unnecessary is removed, in this case, by heating.

Before removing paint from wood, read the rules for the operation of devices.

The use of a heat gun or building hair dryer. These are professional devices that soften the layer with the help of supplied heated air. Work from the mains. Hairdryer is the most effective and safest. It heats the dried layer up to +100⁰ and above, softening it and making it easier to remove.
Gas soldering device does a good job. But it leaves a persistent smell of burning. In addition, the gas in it runs out too quickly. Having too active and nervous neighbors with a sensitive sense of smell, you are unlikely to be able to avoid problems.
Small fragments can be heated over a conventional gas burner. This is acceptable if you decide to restore something insignificant with your own hands. Once the paint has begun to swell and bubbles have appeared, it can be easily removed with a spatula or knife.

Note!
With this method, the likelihood of burning the tree is high.
Therefore, you will have to adjust to the supplied temperature so as not to get a scorched surface instead of a smooth one.

Often craftsmen use blowtorch . It is available, as many have. But it should be manipulated with extreme caution, observing all safety measures. Moreover, soot is inevitable.

Be careful when heat treating wood as you will be dealing with hot fixtures. If it is not possible to work outdoors, ensure good ventilation indoors.

chemical method

Today, a wide range of liquid, jelly-like and soluble washes is produced. If you choose the right tool, your problem of how to quickly remove paint from a tree will be solved as soon as possible.

Even old, tightly dried paint or varnish will simply dissolve or soften when a solvent, acid or alkali comes into contact with them. Then remove all unnecessary, without damaging the structure of the wood, is not difficult.

Arriving at the store, consult with the sales assistant. The fact is that for a certain type of paint you will have to choose the appropriate wash. This is also warned by detailed instructions placed on the package.

A little about how to remove the coating with a special composition.

Dip a thick-bristled brush into the liquid, then apply it to the surface.
Let the wood stand for about half an hour. During this time, the composition is absorbed into the layer.
Apply the mixture again, making sure that the dried paint softens.

Carefully scrape off the soft crust with a spatula.
A damp cloth will help to remove the residue completely.
Wash the treated surface with warm soapy water, thus degreasing it.
After complete drying, the tree can be primed and painted.

Homemade liquids

It often happens that there is no time to look for the required chemicals in stores. Yes, and there is no desire to spend money. But the liquid for removing paint from wood is quite possible to prepare yourself.

Caustic soda mixture

A caustic soda solution works well on almost all surfaces.
Put on old clothes and rubber gloves. Dilute soda with water in an unnecessary container.
Apply the finished solution with a wide brush, leaving no gaps.
Let the liquid soak in. Repeat the process if necessary.
Bubbles that appear indicate that the paint is ready to be removed.

Clean the wooden plane with a spatula. For small recesses, a chisel, a small spatula, or a piece of emery skin is suitable.
Rinse clean surface with warm water and dry.

With a thick paint layer or a large number of hard-to-reach areas, it is more convenient to use not a liquid, but a thick composition.

Soda can be made into a paste by mixing it with water and adding oatmeal.
After reaching the desired consistency and thorough mixing, you can apply the composition to the dried paint.
Wait an hour or two, then remove the paste along with the crust.

Bleach with bleach or bleach

Before removing oil paint from wood, stock up not only with a remover, but also with bleach. Most likely, it will come in handy as an addition to you.

The fact is that under the peeling old layer, the wood is often subjected to decay or the effects of fungi. As a result, the already cleaned layer may have darkening and spots of various sizes.

For fresh coloring, especially with a translucent layer, this is a minus.

Dilute bleach with water.
Apply the composition with a steel wool or a hard brush.
Wait for the substance to evaporate and the wood to dry out.
After the sharp unpleasant odor disappears, you can start applying the final coating.
Work, if possible, on fresh air or well ventilated. Don't forget gloves and a respirator.

Other Methods

As mentioned above, the type of flushing fluid directly depends on the composition of the paint. Like is removed by like.

Therefore, on what basis the paint was made, that component will most effectively wash it off.

Pigment on water based remove with warm water, a stiff brush and a cloth.
Oil paint made from natural ingredients (linseed, fir oil) lends itself well to turpentine. But with a very thick and old (more than two years) layer, you will have to work thoroughly.
To avoid problems, before removing paint from wooden windows, try to determine its composition. As a rule, doors with windows are painted with enamel products. In this case, you can use acetone or a special solvent.

Precautionary measures

All of the above methods, to one degree or another, pose a danger to you and others.

Compliance with safety regulations is very important, otherwise problems and troubles are inevitable.

Provide good lighting otherwise there is a high risk of injury.
To work with large objects, adjust a sturdy table or enough free space.
Planks, bars, frame parts are conveniently clamped in a vice, especially during mechanical cleaning.
Wear safety goggles, the pieces of dry paint are very sharp. They can injure the eye by flying into it.
You will need a respirator anyway. It will prevent the inhalation of dust, burning and soot, as well as harmful chemical compounds.

When working with caustic aggressive compounds, be sure to wear thick household gloves.
Allocate old clothes and shoes for work, which, in case of damage, are not a pity to throw away.
If acid or alkali gets on the skin or mucous membranes, rinse the affected area with warm water as soon as possible. If this does not help, contact your doctor immediately.
Follow the measures fire safety. If you work with heating devices, prepare fire extinguishing agents.
Cleaning items is strongly recommended not to be done indoors, but outdoors. Choose a fine day, without frost or precipitation. (See also the article.)

Conclusion

There is an erroneous opinion that the removal of paintwork is a simple matter, and does not require special attention. However, this is not at all the case. Only strict observance of the rules, strictly sustained technology will give a positive result.

How to properly prepare a wooden surface, the video in this article will show you. It describes all the stages of work.

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 a noble look to 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 on top of it, or still make a preliminary cleaning of 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.
The texture, which may not coincide with the qualitative characteristics of 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-painting treatment will be sufficient. A thick layer of paint or a large number of layers accumulated over many years should be removed. on concrete and metal products, characterized by a hard surface, it is much easier to get rid of the old coating than on wood - a soft material that is 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 can be further used.

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 turning to professional masters is better than independent actions. 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 the work surface is carried out with the help of 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 chemical method 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 electrical wiring, since at high temperatures the latter can easily ignite. 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. Fairly effective mechanical way, which is a scraping of 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 a wooden surface of 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

When working with an electric drill or grinder, the paint is removed dry, so the work process takes place in a large cloud of dust. Therefore, be sure to use a respirator, goggles and gloves. Before removing old paint from wood mechanically, you should pay attention to the type of wood, since improperly selected abrasives can significantly damage its surface. Coarse-grained paper can leave significant scratches on the surface, especially if the work is carried out with some effort. Therefore, it is better to change to a fine-grained analogue and not make great efforts when in contact with a wooden surface. Scratches resulting from mechanical impact should be puttied and treated with primer.

Which way to choose?

How to decide how to remove old paint from a wooden surface? If the area to be treated is large and even, apply mechanical method using various power tools. If you cannot connect to the network, you can use chemicals, after the action of which it is necessary to remove the old layer using ordinary scrapers.

Cleaning with caustic soda

How to remove old paint from wood flooring? If you are unwilling or unable to use the above methods, you can try using a solution of caustic soda. This method is optimal for any surface, but requires great care.

Components for the workflow:

old clothes;
latex gloves;
brush;
putty knife;
cut plastic bottle;
mortar;
caustic soda.

The “softener” of the paint is prepared from a part diluted in three parts lime mortar. The resulting composition is applied with a brush on the work surface for 10-20 minutes, after which the layer old layer paint will start to bubble. To speed up the process, it is recommended to scrape the surface with softened paint with a stiff brush or knife. Then you need to carefully remove the paint with a spatula, wipe the surface with a degreasing solution or rinse thoroughly with water.

How to remove old paint from a wooden surface? Means that have proven themselves in this matter are caustic soda and oatmeal, from which you can easily prepare an effective paste. It is only required to dilute these components with water, and then apply to the work surface.

After a while, it must be removed along with the paint and rinsed with water. In case of contact with the skin, this drug must be removed immediately.

Acetone to the rescue

Do you know how to remove old paint from a wooden surface with acetone? This tool, perhaps, like gasoline, is the most popular among people who are faced with the problem of removing an old layer of paint.

Acetone, which is a solvent, destroys molecular structure substance, and it gradually begins to disappear from the surface. You can remove paint in this way on a small surface. Handling should be carried out very carefully due to the toxicity and flammability of these liquids. Before starting work, the room should be well ventilated.

Also, for cleaning wooden surfaces, some craftsmen use a solution of laundry soap and turpentine.

New old things

It is quite natural that the renewal of surfaces is a laborious and sometimes quite protracted process. Maybe sometimes it's even easier to buy new wardrobe, put new door and lay flooring. But still, being among your favorite things that have been around you for years is much more familiar and comfortable. Maybe you should try to breathe new life into them?

We started the renovation and do not know how and how to remove the old paint from the wood before covering the old wooden surface with new paint. Update wooden furniture, frames or doors for various reasons. It can be really a pity to throw a quality one in the trash wooden material, such a decision may be made for economic reasons, when there is no money to buy new furniture. And wooden furniture is now expensive. Sometimes it will be cheaper to repaint the old one than to buy a new one.

Or maybe you just want to update the interior and change color scheme design in the house. Also, paint can simply fade in the sun, losing its original color and shine, so it will have to be updated. Or maybe, for example, wooden furniture was heavily stained with paint during finishing works and must be removed from the surface. Of course, such a paint-stained surface should be cleaned.

Before repainting an old wooden surface with new paint, it is necessary to carefully remove the old paint, prime the wood, and only then paint it again. If this is not done, but simply painted over the old paint, there will be no sense in it - firstly, it will be ugly, and secondly, the paint will wrinkle and peel off.

How to remove old paint from wood

There are three main types or methods of removing old paint from wooden surfaces: mechanical, thermal and chemical. In the course of the work, these types can be combined, for example, carried out in turn, if the first one turned out to be not very effective.

Ways to remove old paint

Chemical (caustic soda solution, special washes).
Thermal (building hair dryer).
Mechanical (metal brush, scraper, spatula).

Mechanical methods removal of old paint are different.

Manually. Arm yourself with a spatula, a scraper and boundless patience and nerves and try to remove the old paint by hand, only carefully so as not to damage the wood. This method is quite lengthy, time-consuming and exhausting.
Metal brush you can also try to clean off the old coating, and then just wipe the surface with sandpaper.
Using power tools can be processed quite large areas surfaces. For example, using a grinder (angle grinder) or a drill with special recommended nozzles that can easily cope with this task. It's quite difficult. Be sure to use safety goggles or special eye shields, a respirator for respiratory protection when working.

Thermal methods for removing old paint from wood relatively popular and effective. Nowadays, for this, manufacturers of professional manual construction tool a building hair dryer was invented, efficient and easy to use.

Building hair dryer. Very easily and quickly you can remove the old paint with a building hair dryer. You simply heat the surface with it, a jet of hot air melts the coating, it bubbles and peels off the surface, after which it can be easily removed with an ordinary construction spatula. Only with a spatula you need to carefully remove the paint so as not to damage the tree. If the paint needs to be removed from the recesses or any depressions, you can try to pull it out with a small trowel or some other suitable tool. A building dryer is very effective, but you should take into account the temperature to which it can heat a plane or surface and be ready for this. Work with such a tool should be careful, according to the rules of operation, so as not to damage the surface. Be sure to use safety goggles or special eye shields, a respirator for respiratory protection when working.

Chemical methods for removing old paint relatively expensive in price, special washes, liquids and solvents can even cost more than the paint itself.

Washing off old paint. V construction stores in departments coatings you can buy a chemical agent for removing paint from wood, this is a kind of liquid. Before buying, you need to study it, as they are different type. You should choose based on the type of paint that the furniture was painted with and in our case it should be suitable for removing coatings from wooden surfaces. Yes, universal products for all types of paint are also sold, there are some. By the way, there are such washes in a thick state, in the form of jelly or paste, which are convenient to use, for example, on ceilings.

The method of applying such a wash is as follows: the liquid is applied in an even layer on a wooden surface using a roller, brush or spray gun. Then you should wait 10-15 minutes. After this time, the paint should swell, after which it is removed with the same spatula. This chemical has a strong odor, so open all windows before use to keep the area well ventilated and wear protective gloves to avoid burning your hands. Also, do not forget to protect the respiratory organs and eyes from a pungent odor.

Repair work is often very dusty and dirty, so you should prepare the room for them in advance, take out the furniture, close protective film everything that is not possible to take out of the room.

Attention! Important! During repair work, follow safety precautions, protect your skin, respiratory tract and eyes with special protective equipment, this is very important! Take care of your health!

Faded or cracked paint on wooden frame although it gives the house a vintage look, it is in no way its decoration. Of course, unless it's a design idea. To learn how to properly remove old paint from wood, read this article.

Peculiarities

Removing old paint from window frames, doors, old furniture and others wood flooring requires certain knowledge and skills. How to determine that such a procedure is really needed?

It all depends on the number of layers on the wood. If the previous paint was applied in one layer, you can start painting without removing the coating. It will be enough to go over the paint with sandpaper until the shine disappears, and the old coating acts as a primer. It is important that the product is free of paint streaks and flaws in the texture, then the fresh paint will lay down in an even, beautiful layer.
The color of the previous coating plays a huge role. If you want to apply light paint over a dark layer, remember that the shade will most likely not turn out the way you want. In this case, the best option is to apply two or more layers of paint.

Please note that if the product was painted more than 5 years ago, then, most likely, cracks and swellings have already formed on it. Moreover, modern materials differ from previous analogues not only in quality and color fastness, but also in texture. In such a situation, the coating will have to be completely removed.

Types of coatings

There are several types paintwork materials for a tree. Before removing old paint from wood, it is worth determining what type of coating it belongs to. This will allow you to choose best way its removal.

The most popular means for painting wooden surfaces was and remains water-based paint. It is characterized by matte colors, moisture-repellent properties, a wide color palette and an affordable price. Water based paint is waterproof and non-waterproof. The first is quite difficult to remove from any surface.

To determine which water emulsion the product is covered with, moisten it with water and leave it for a while. If cracks and peeling are observed, then the tree is covered with non-waterproof paint.

No less popular are water-dispersion (or latex) paints. They are most common in the construction industry, and all thanks to the many advantages. latex paints absolutely harmless, have a rich palette of colors, fireproof. They are characterized by high durability of the coating, they are effective protection against fire.

For coloring decorative elements Acrylic paints are often used from wood. There is even a special stained acrylic that can be applied to glass, wood, plastic and even fabric. Part acrylic paints includes water, a coloring pigment, acrylic acid and a film former that contributes to the rapid solidification of the layer.

acrylic coating able to withstand severe frosts, and the brightness of the color is maintained even after many years.

Previously, oil paints were in the lead in paint and varnish products, but today they are slowly becoming obsolete. Their lack of demand is due to toxicity, bad smell, the complexity of application. If the tree is covered oil paint, no other will hold on top.

Often, whitewash is used as a coating for wood, which at all times was considered an excellent antiseptic. Whitewash protects walls well, disinfects the air. Today it is used mainly for processing hidden wooden parts: floor beams, floor joists, rafters.

Process technology

There are three ways to remove old paint from wood:

mechanical;
chemical;
thermal.

The mechanical method of removing paint from wood products can be carried out manually or using special tools. Everything necessary materials and tools for performing work, for example, such as sandpaper or a spatula, you can easily find in the nearest hardware store.

It should be noted that oily materials quickly adhere to the abrasive coating, so the mechanical method of removing such a coating would be too expensive.

When choosing sanding paper, pay attention to its grit. Coarse-grained nozzles contribute to the formation of depressions and scratches in the wood. Such paper is best used if the coating consists of several layers of paint. Change the nozzle as soon as the tree starts to show. Remember that such work should be carried out on a dry surface, always observing safety precautions.

The chemical method of processing involves the use of special acids and solvents, which should be selected taking into account the type of old paint. Manufacturing companies claim that these products ensure the dissolution of any paint, regardless of its age. However, as practice shows, such liquids are able to actively fight only with a fresh coating (up to 2 years ago).

Chemical reagents are optimal for removing acrylic and water-based paints and varnishes.

Using chemicals, the surface of the product is covered with a thin layer of liquid. It is necessary to wait a certain amount of time indicated on the package - this will allow the old paint to soften and it can be quickly peeled off the wood with a conventional spatula.

Working with chemical compounds it is necessary to take care of the ventilation of the room or deal with the removal of the coating on the street. Need to work in overalls, respirator, goggles and rubber gloves.

The thermal processing method is suitable for removing paints based on oils or drying oils. Judging by the name, it becomes clear that the treatment involves heating the coating until the layers of paint soften. Heating is usually carried out using a building hair dryer or iron.

thermal effect perfect option if the paint has been applied for years. With prolonged heating, even a too hardened coating will soften.

It is worth noting that when heated, toxic substances will begin to be released, so put on a respirator during work and open the windows.

Training

If the ceiling and walls are painted with a non-water-resistant emulsion, the room must be prepared before work is carried out:

floor, furniture, decor items and even stretch ceiling cover with foil or newspapers;
prepare protective clothing, goggles, gloves, a respirator;
prepare a container with warm water, if required by the processing method;
prepare in advance all the tools that you may need.

When removing an old layer of paint from plastic, it should be preheated to 60-70 degrees. It is better to postpone such operations for summer time in order to exclude plastic deformation due to temperature differences.

A building hair dryer is often used to heat the surface during heat treatment. Under the influence of hot air, blisters form on the coating, which will facilitate the removal of the coating.

When painting wood window frames drops of paint often fall on the glass, removing them, in fact, is not so simple. Removing paint from a glass surface requires special skill. Usually small dirt can be simply scraped off, but this requires accuracy. You can slightly heat the glass with a building hair dryer, this will help soften the already hardened paint.

Some experts use foil: a layer of foil is applied to the glass, and a heated iron is gently passed from above. This method will allow you to remove even large smudges.

Often, during paint work, drops of paint fall on metal surfaces. Removing paint from metal also requires preliminary preparation. First, the surface must be cleaned of dust and dirt, otherwise the process may slow down significantly. In addition, before carrying out this operation, it is desirable to dismantle the elements that may be damaged during cleaning.

What can be processed?

Usually wood is treated with various chemical compounds that exfoliate upper layer coatings. If the wood is covered with shellac, then it will be more efficient to use ordinary denatured alcohol.

It is good to process a single coating with liquid formulations. But powder products are suitable for processing a large area.

Tip: to clean the paint from the surface, use a spatula, after rounding its edges with a grinder - there is a risk of damaging the tree with sharp edges during the procedure.

Coating machining is one of the effective ways paint removal. It can include stripping with sandpaper manually or with the help of grinder(diamond cup).

How to delete?

In addition to the above means, special chemical washes are often used, which include dimethyl chloride, formic acid and other organic substances. Such reagents are distinguished by a rapid decomposition process, therefore they are considered practically harmless.

Important! A chemical remover copes quite well with a water-based emulsion: if the product is covered with one or two layers, it will be easy to wash it off with a store-bought reagent.
