It is impossible to remove paint with a building hair dryer. Removing paint with a blow dryer

Different paints are removed in different ways: some are easier, others sometimes baffle even experienced builders. It all depends on the type of paint and the surface on which it is applied. In order not to waste time searching for information and various experiments, study this article carefully. In it, we will look at all possible ways to remove paint, describe their advantages and disadvantages, do not forget about security measures, and also mention ways that a smart person should not use at all.

Remove or leave?

Painting the walls of kitchens and bathrooms was very common in interior design during the Soviet period. Therefore, many of us are still faced with the need to remove paint from walls, floors and ceilings, for example, before leveling them or before laying ceramic tiles. Should it be removed or can the floor and walls be restored over the painted surface?

It all depends on what you plan to do next. If you decide to sew up the wall with drywall, you can leave the paint on the wall. But in most cases, you still have to remove old paint from walls and ceilings, since the painted surface has almost zero adhesion (adhesion) to tile adhesives, cement plasters and any building mixtures. So if you decide to apply plaster on top of the paintwork - the joy of the repair you have made will not last long.

How to choose a paint removal method?

How to choose the best way to remove paint?

Four factors influence the choice of one or another method:

the surface on which the paintwork is applied, and what you plan to do with it next;
type of paint, number of layers and strength of its adhesion to the surface;
tool available;
the budget you have.

The paint itself can be of several types: water-based, acrylic and oil. The most difficult thing is to remove oil paint from concrete surfaces. Therefore, we will take a detailed look below on how to remove old oil paint.

Of course, you may not know what kind of paint is on the walls of your home. In this case, you still have to experiment a little with removal methods on a small section of the wall. Try the least time-consuming, gentle ways first.

The paint can be applied to metal, wood, drywall or concrete. The most difficult thing is to remove oil paint from bare, unplastered concrete from the ceiling.

What do you need?

Depending on the removal method you choose, you may need the following tools and materials:

spatula, iron scraper or wide chisel;
chemical paint remover, brush or roller;
ax for notches;
building hair dryer;
electric drill with a special nozzle;
grinder with a wide nozzle;
water;
respirator, goggles, gloves, other personal protective equipment.

Description of removal methods. How to remove oil paint?

It is especially difficult to remove oil paint from walls and ceilings unless they have been previously plastered. In general, there are not so many ways to remove oil paint. To come up with something new, completely harmless, fast and not requiring much effort, unfortunately, science has not yet succeeded. Therefore, we consider all possible options with their pros and cons.

In general, all existing paint removal methods can be divided into three groups:

chemical;
thermal;
mechanical.

chemical method

The essence of the method: prepare a chemical solution for removing paint according to the instructions, apply it to the surface with a brush (movements are best done in one direction) or a paint roller, give time to soften the paint and remove the paint with a remover with a spatula, a metal scraper or a brush with a metal bristle. This method is the fastest, but the smell can remain for a long time. Also note: if the paint has been applied in several layers, the use of a wash does not guarantee perfect removal immediately. It may need to be applied in two or three steps.

Removing paint with chemicals is a method that has a lot of disadvantages. Firstly, it is highly toxic and has a sharp specific persistent odor, secondly, it can cause burns if it comes into contact with the skin, thirdly, it requires special disposal (in no case into the sewer), and fourthly, it is not cheap.

If you still decide to use chemistry, be sure to follow the safety rules. Work with reagents only in well-ventilated areas using personal protective equipment (respirator, goggles, gloves), pregnant women and children should not be in the room. It is necessary to completely protect all parts of the body from chemicals. this mixture of acids and solvents is very aggressive and contact with it will lead to disastrous consequences.

You can also try the following methods. To remove paint from a plank floor, moisten the boards thoroughly with water and cover with a thick layer of soda ash. Cover it all with damp burlap and leave for a day without letting the burlap dry. A day later, you can easily clean the paint swollen from dampness with a spatula.

You can also remove old paint with a mixture of potassium carbonate and lime. Mix in water 1.2 kg of quicklime and 400 g of potassium carbonate (or soda ash) until thick. Apply the mixture to the surface and keep it for 12 hours. After that, the old paint will be removed easily.

Another option is to remove oil paint with liquid glass. Lubricate, let dry well. The silicate film should begin to peel off along with the paint. Repeat the procedure several times.

thermal method

Removing paint with a building dryer is a method that has been known for a long time. Heat the painted surface with a building hair dryer until the paint softens and with a spatula (another scraper) clean off the soft paint from the wall, doors or floor. If there is no hair dryer, take a wide sheet of foil and heat the paint through the foil with an iron.

The method is not applicable in places where electrical wiring passes or there is a decorative coating that can be damaged by high temperatures (for example, plastic).

But this method is ideal for removing paint in places where vibration and shock are unacceptable (for example, glazed doors, window frames, etc.). But a very significant drawback of heat treatment is the pungent smell of paint and the release of toxic substances when it is heated. Therefore, it is necessary to reliably protect the respiratory system and use this method only in well-ventilated areas.

mechanical method

Taking into account the physical properties of the paint, which releases strong toxic substances during chemical and thermal removal, the most optimal is the use of a mechanical removal method.

The well-known old grandfather method - laborious, slow, but cheap, non-traumatic and least harmful - notching the walls with an ax. To remove the paint, you will need, in fact, an ax, water and muscles. First, make notches with an ax, then sprinkle the wall well with water, wait a few minutes until it is absorbed, and clean off the paint with an ax. To work faster and more efficiently, you need to choose the right angle of inclination of the ax.

Most often, this method is used if further wall cladding with ceramic tiles is planned, since the adhesion of tiles to a non-smooth surface is the most ideal. Although laborious and slow, the method is quite acceptable when you need to process a small area, and is almost ideal in poorly ventilated areas.

Mechanized mechanical methods

To speed up the mechanical removal of paint from a concrete wall, make your work easier and increase its productivity, we recommend using mechanized methods.

You can use a grinder with a wide range. With such cleaning, the dust will be very, very much: after a minute of work, you will have to wait twenty minutes until the dust settles. But today there is already excellent new equipment with a built-in vacuum cleaner that allows you to remove paint from the wall as cleanly as possible. Watch video:

There are two more ways with nozzles for a puncher.

The first method is to use a chain as a nozzle on a drill. This is a fairly effective and cheap method for removing paint and rust from concrete, wood and metal surfaces.

It is possible to use chains of two configurations. The nozzle of the first configuration, the so-called paint remover, is shown in the photo and in the video below.

The nozzle of the second configuration is a chain of 13 links with a link thickness of 5 mm. The center link rotates 6 links on each side. A 6 mm bolt is used as the basis. Put on the chain and press it well with the nut. The drill turns on by turning to the left.

If the extreme link flies off on one side, it is necessary to remove it from the other side for balance. You can remove the paint until there are at least three links on each side. Unlike a brush, which produces a lot of fine dust, the chain beats off the paint in pieces. You must be protected from mechanical damage.

The second method of removing paint from a concrete wall is to use a brick crown as a nozzle for a puncher.

How to remove acrylic paint?

Acrylic paint can be removed with a good metal brush or even coarse-grained sandpaper. This is handmade, so don't forget the gloves. If the paint is good, it will not come off well. In such a case, you can use the removal methods described above for oil paint. Keep in mind that if you plan to cover the surface again with acrylic, it will fit well on any acrylic paint even without cleaning.

The Worst Ways to Remove Paint

Ways not to remove old paint:

Thermal method using open fire. It is highly flammable;
Chemical washing in unventilated areas.

And remember. Whatever method you choose to remove the paint, be sure to use personal protective equipment. This is especially true for the respiratory and eye organs. After all, when cleaning surfaces of old paint, you are exposed to several hazards at the same time: dust, toxic chemicals, and small particles of paint flying off the wall.

A technical or building hair dryer is far from the last place in the home master's tool kit. With the help of a hair dryer, you can easily remove old paint, dry surfaces, defrost water in the pipeline, and give plastic parts the desired shape. A hair dryer is indispensable when laying roofing material - with a hair dryer you can cut the roofing material, heat it up, or melt it. A hair dryer is used when installing heat-shrink insulation, welding linoleum, when soldering with tin or silver.

With a strong desire, you can make a technical hair dryer with your own hands, but the problem may arise already at the first stage - what to make a reliable and safe case from. With a sufficient selection of hair dryers on sale, it is better to buy a ready-made hair dryer.

Working with a technical hair dryer

When working with a technical hair dryer, be careful. The hair dryer heats the air from 300 to 600 degrees. Protective gloves will save your hands. When softening the paint with hot air, toxic substances are released. Put on a respirator with a charcoal filter.

Use the technical hair dryer correctly, then it will serve you for a long time.

Do not overheat the hair dryer during operation, take a break every 10-15 minutes.
The closer you hold the hair dryer to the surface being treated, the more it overheats.
Do not turn on the hair dryer immediately to the maximum operating mode.
Before turning off the hair dryer, switch it to the minimum heat to cool it down.
The nozzles of the hair dryer get very hot, so do not place the hair dryer on surfaces that you do not want to ruin.
Do not change the nozzle until it has cooled down - you can get a severe burn.
When removing paint from the window frame, unfasten the glazing beads and remove the glass. Glass can easily crack when hit by a jet of air.
Be careful when cleaning old paint from the floor. Hot paint particles can fall between the floorboards and cause a fire.

Do-it-yourself hair dryer repair

All electrical tools tend to break. With minor problems, the hair dryer can be repaired with your own hands. The main working parts of the hair dryer are a heating coil, a fan, an electric motor.

Try to find the cause of the problem. Perhaps the power cord broke, or the wires burned, the spiral burned out.
Arm yourself with a screwdriver, a soldering iron, find the hair dryer diagram, which is in the instructions for working with a hair dryer.
Prepare the surface on which you will disassemble the tool.
Remember the sequence in which you disassemble the hair dryer. It is very good to use the camera to photograph all the stages of disassembly. This will help you not to puzzle over where to attach the extra parts left after the assembly.
Start by checking the plug, cord, contacts. Replacing the cord, buttons or soldering wires is easy with certain skills.
If the engine breaks down, or the fan - it is better to take the hair dryer to the workshop.

Nozzles for technical hair dryer

For convenience of work there are special nozzles for the technical hair dryer. Nozzles are made of steel and withstand high temperatures.

Also included in the sale kit are devices that will help remove paint from hard-to-reach places.

There are nozzles for welding, soldering and heat-shrinking pipes. For soldering thin pipes, a reflective nozzle is suitable.

To heat up and bend a plastic pipe, use reflex nozzles.

A wide flat nozzle works well for removing old paint from the surface. Protective and reducing nozzles are used to remove paint from the window - they help direct the air stream to the right place and protect the glass from overheating.

How to remove old paint

To remove old varnishes and paints, there are many chemicals. The composition is applied to the surface to be treated, after the paint softens, it is removed with a spatula. The disadvantages of this method include the pungent smell of the chemical composition, the inability to qualitatively remove paint from large areas. Old paint is difficult to attack even advertised chemical paint removers.

Mechanically, you can clean the surface with a grinder or grinder with special nozzles.

Removing old paint with a building hair dryer is more practical and convenient than other surface cleaning methods.

For work you will need

technical hair dryer
extension
hair dryer attachments
spatula and special tools for scraping paint
brush
protective equipment - gloves, respirator

Do not hold the hair dryer too close to the surface. From a distance of 5-10 cm, warm up small areas. When the paint begins to bubble, it must be removed with a spatula. A spatula, unlike a spatula, is more rigid, it is more convenient for it to remove peeled paint. You can take a narrow spatula.

Do not heat a large surface at once. For convenience, take an extension cord. Paint is removed more easily from wooden surfaces than from metal or plastered and painted surfaces. Ventilate the room more often.
Hold the hair dryer by the handle, do not cover the air inlets with your hand - it can quickly overheat. When removing paint from a window, it is better to remove the frame - it is more convenient to work this way, and it is easier to get to hard-to-reach places on the window block.

Hold the hair dryer in your right hand, directing the air flow to the right place. When the paint begins to swell and bubble, immediately remove the softened paint with your left hand with a spatula.

Use a brush to remove small frozen pieces of paint.

__________________________________________________

Surely, many people in their lives had to remove old paint from various kinds of surfaces, while this procedure can not always be called the simplest and easiest. First of all, removing the old paint coating requires a lot of work and patience. Fortunately, today this problem has been almost completely solved, since such an important tool as a building hair dryer has appeared. You can buy a tool of this kind today in almost every hardware store.

In turn, the building hair dryer does an excellent job of removing old paint, as well as many other difficult tasks. It is worth highlighting the advantages of using this device separately. It’s worth saying right away that in addition to the dignity of using the technique, the article also describes small secrets regarding how to properly and effectively work with a hair dryer.

They are used in numerous ways in the construction site. For example, with its help, you can simply dry a new wallpaper coating or solder non-refractory types of metals.

It is worth dwelling separately on the process of removing the old paint coating using this unit. A building dryer is the ideal tool for this kind of work. In this case, the paint coating after a while begins to be removed from the surface during the passage of hot air. Using this method not only speeds up the entire process, but also guarantees much better results in the end.

As for the very procedure for using the device, everything here is not as complicated as it might seem at first glance. Even a novice builder can work with it without any special knowledge and skills. And if you have ever used an ordinary household hair dryer, then when working with a construction analogue, you will not feel a strong difference. It is worth noting that the work between these two devices differs only in the temperature of the outgoing air. Of course, this indicator is much higher for a building hair dryer, and therefore it is worth taking care of additional protection for hands in advance so that you do not get burned when working with the device. Ordinary cotton gloves may be suitable for this purpose.

In the process of removing old paint, in addition to the device itself, it is additionally worth using a spatula or some kind of additional scraper. In order for the old paint to move away from the surface faster, adjust the temperature of the outgoing air in the appropriate direction.

If the paint layer is thick enough, then the temperature of the hot air jet emitted should be appropriate. It is worth warming up the surface directly in front of the scraper or spatula itself, while moving forward. If you work inside a building, then you need to take care of hourly breaks in order to ventilate the room. Otherwise, there is a risk of chemical poisoning arising from an excessive amount of vapors that appear during the heating of the varnish-paint material.

In addition, there are some tricks when removing old paint with a building hair dryer. Thus, if you use a spatula or a scraper together, then you should use only its sides. This is due to the fact that the side of the spatula is more blunt, and therefore it will remove the old layer more efficiently.
In addition, do not warm the surface too much. Otherwise, this can greatly soften the paint, making it difficult to clean off. In this case, it will simply begin to stick to the work surface. It is necessary to evenly clean the entire coating from soft layers, while carrying out successive and progressive movements with a spatula or scraper.

Very good news for site users. Another video is ready on the topic: "How to remove old paint." Everyone must have experienced this. Since before each conceived repair work, before proceeding with the installation of walls, windows, doors, etc., we need to prepare the base, namely, clean off the old paint, level the required surface and then proceed with the necessary restoration or finishing steps.

How to remove old paint

Therefore, in order for you to have a good way to peel paint off the surface in your arsenal, I suggest watching this video. Since the plot takes place without additional comments behind the scenes, I will try to comment on the text in the article below.

To start work, you need to prepare the necessary tools that we will use, namely this: a building hair dryer and a special scraper. With which we will remove a layer of paint. These tools are shown in the photo.

Also included in the preparatory work is to ensure after the repair procedure, namely: the entire layer of paint will fall straight onto your flooring, and some of the paint that we have peeled off the surface, after exposure to a building hair dryer, will be in a soft state. Therefore, in order to avoid damage, we will cover the entire area of the floor covering, on which the paint will fall, either with a board or with a cloth.

Let's go directly to the process itself:

On the video "how to remove paint from the surface", we see how the removal process takes place. You choose the method of hot air action on the object and removal of melted paint from the surface. Since the speed of your work depends on it.
We turn on the first speed of the hair dryer, wait a minute until it warms up and then turn on the second speed, after which the hair dryer starts to heat up the surface where the old paint is located more strongly. After the hair dryer has heated the paint to the state we need, we remove the paint with a special scraper, which is shown in the photo in the right hand. We can find out to what state we need to heat up by observing the paint itself, namely, it should be covered with bubbles. After that, we boldly begin to peel off the paint, and direct the hair dryer to another area. Use only cloth gloves. It is also advisable to wear protective goggles.

Everyone who has ever encountered a problem knows how laborious it is to prepare the surface for subsequent finishing. It is especially difficult to remove the coating if the paint was applied in a thin layer, a quality material was used. As a rule, this stage takes place in the most protracted mode, since the dismantling of the old one does not make fundamental changes in the room and is difficult to perceive as a repair.

One of the most common questions asked when performing cosmetic repairs is what and how best to remove the paint. There are many techniques to choose from based on what paint was used, what surface it was applied to, and what kind of finish will be applied to the treated surface.

If the next step after processing is to cover the surface again with paint, then you should decide. Should it be removed in whole or in part.

Previously, the main paint for repairs was oil. If with such a paint composition the wall surface remains even, has no chips or cracks with bubbles, the next coat of paint can be applied over the old one. If there is damage to the surface in the form of a peeled off old layer, then partially, where the paint began to fly around, it must be removed.

Although all modern paints, regardless of what basis they are produced on, whether it is water-based or acrylic or silicone, have a high adhesion. But for any composition, an important condition is the presence of a flat surface. Therefore, if the wall is not even and is to be puttied, the old paint must be removed completely.

This is due to the fact that the putty has a low adhesion to paints and varnishes and can come off with subsequent layers. Oil-based paints are the hardest to peel off. The fewer layers were applied, the more difficult it is to get rid of it. A thick layer clears faster.

Instruments

To carry out paint removal work, you may need the following tools and tools:

protective equipment for the skin of hands, face, eyes. It can be rubber gloves, construction glasses, a face mask;
knife, pointed spatula or chisel;
building hair dryer or blowtorch;
liquid with a special chemical composition for removing paint;
brush;
perforator or drill;

Paint removal methods

When choosing the most optimal way to remove paint, you should first consider from which surface it will be removed. For example, the thermal method is ineffective if the paint has been applied to putty or concrete.

There are three methods for removing paintwork. These are mechanical, thermal and chemical methods. It is possible to use each of them independently, without resorting to the services of specialists. In the photo you can see how to remove the old paint, depending on the method chosen.

mechanical method

The advantage of this method is the absence of toxicity during processing. It is good to use in closed spaces that are difficult to ventilate. For example, in the bathroom, kitchen. It can be used if there are children, pregnant women, pensioners in the apartment during the repair.

When choosing this method, you must first decide on the tools available at home. If special power tools are not available, then work can be done using conventional tools.

One of the most common and proven over the years manual processing methods is the method using an ax and water. This method is suitable for removing old paint with your own hands from walls, door jambs, doors.

With an ax, serifs are made in the course of applying the paint. Further, the wall is abundantly wetted with water. Within 10 minutes, water soaks into the space formed after the serifs, forming a small porosity for air to penetrate under the paint, to facilitate its removal.

At the end, with quick movements from top to bottom, it is cleaned off with an ax. The chisel is suitable in narrow areas or those requiring the greatest care, for example, in the area of \u200b\u200bwiring, sockets.

Work can be done with a hammer and chisel. The scheme consists of hammer blows on a chisel, which is attached to the wall.

The mechanical method is the most economical and spends the greatest amount of physical effort and time.

To remove paint from the surface of the walls, for example, in the bathroom, you can use a drill or grinder. For these works it is better to have special nozzles. If they are not, then it is worth preparing for the fact that the whole room will be instantly covered in dust in the air. The most convenient nozzle is considered a grinding wheel.

Paint is best removed from concrete with a drill. For her, special nozzles are supplied for such work. The best paint remover is considered to be in the form of several interconnected chains.

chemical method

The chemical method will help to quickly remove the paint. A special solvent is used to carry out the work. It must be applied to the surface and allowed to soak for 15-20 minutes. After this time, repeat the procedure several times.

As a result, the paint will soften and can be easily removed with a few strokes of the spatula. The chemical method is more suitable for a surface that was painted no more than two years ago.

It should be remembered that the area of penetration of evaporation from the solvent is very large. Such a method may not be harmless not only for the workers themselves, but also for the residents of neighboring apartments.

thermal method

This method is ideal for removing paint from floors. To carry out the work, a building hair dryer will be needed. This method is most effective for removing old paint from wood.

The technology is very simple. It is necessary to direct a hot stream of air to the surface area to be treated and wait until the paint begins to swell. Finally, clean the resulting mass with a conventional spatula.
