How to consider old paint. How to remove the paint from the walls in the bathroom. When to remove the oil paint from the walls is impossible

ABOUT dean from the most "patients" questions arising in cosmetic and capital repairs - how and how to remove or remove the old paint. The task is not easy, because when creating new types of paints, their manufacture, the task of developers is directly opposite - how to make paint stable and stronger. Nevertheless, ways to clean surfaces from old paint exist, and many of them, we will also tell me further.

Let's start with removal, removal from various surfaces of the coating of oil (alkyd) paints. There are three ways that this task is solved: thermal, mechanical and chemical, as well as different combinations thereof. The most common of these methods is thermal, with partial use of mechanical cleaning.

Thermal way to remove old paint (heating)

This process is performed as follows: the old paintwork is heated to the softening temperature and in this state is considered a steel spatula. Heating coating is performed using a soldering lamp, a gas burner or an industrial hair dryer.

The thermal method is simple, effective, but has its drawbacks and restrictions. For example, it will not be possible to remove the paint from the plastic, since most plastics begin to deform for two hundred degrees Celsius. In addition, the use of devices that create a jet of hot fire is not always safe. In the closed rooms, another factor restricting the use of the thermal method is entered into, is the release of toxic substances from the paints when heated.

A large disadvantage of the thermal method of cleaning from old paint is also the fact that with it can be cleaned far from any surface, even if there is a heat-resistant. It is not very effective when cleaning massive metal surfaces.

The technology of using thermal paint cleaning is simple: one hand hold the heating device, directing the flame or hot air to the surface, moving the jet as the paint is softened, and the other hand, in the course of the movement, are softened with a spatula. The skill of work simultaneously with two hands is produced literally for ten - fifteen minutes.

There are also nozzles from metal chains, often homemade, to remove paint with a drill - this method is rude, but often convenient.

In addition to the specified tools, there are more specialized devices - plane grinding machines and credit mills. The latter are effective when cleaning with paint plastered, stone, concrete and other, similar surfaces, however, for metal are unsuitable.

The plane grinding machines for painting oil compositions are ineffective, since the sandpaper quickly comes in disrepair, causing paint, but sometimes, especially if high-quality processing of small areas is needed, they are not replaceable. In addition, most of the water makers are well removed.

The technology of cleaning the old paint with power tools is even easier than in the thermal method: the working part of the tool is pressed against the surface being processed and as the desired degree of cleaning is achieved, it gradually moves.

Another tool that will help in removing the old paint - the perforator. With the help of a wide shovel nozzle, often homemade, you can remove the old paint from concrete bases, knocking it by a perforator. The disadvantage of this method is that together with the paint it is possible to damage the basis itself, so this method is more suitable for the removal of paints from durable concrete. Together with the paint, such a way is well removed by the shtlock and plaster, with →.

Sandblasting method for removal, removal of old paint

Another common method of mechanical cleaning from old paint is sandblasting. The principle of sandblasting is that a jet of air or water is directed to a purified surface under high pressure, into which abrasive particles are added (most often - ordinary sand). Peschinki, hovering at high speed about the surface, it is perfectly cleaned not only from paint, but also from rust, from various kinds of other persistent contaminants.

The disadvantages of the sandblasting method include the relatively high cost of the equipment and the need to have certain skills for servicing devices and the production of the work itself.

Repairs in apartments of the Soviet Sample often involves the removal of old paint, mostly oil. Yes, and remove the water-emulsion, diligently held for years, is very difficult. Plus, the surface is different, because, in Soviet times it was painted absolutely everything - concrete, wood, plaster and even tile ...

Why shoot old paint

Is it worth removing the old paint depends on which finishing is planned for this surface. If the owners wish the wall to paint or stick wallpaper, put the ceramic tile or apply decorative plaster, then the layer of old paint coating must be removed. Otherwise, the finishing finish will simply begin to fall off with time. And if the walls are, for example, shifting with plastic or plasterboard with the use of the root, then remove the old paint is not necessary.

Why delete old paint from the wall, if, for example, planned plastering? After all, you can cover the wall of the primer and plastering? But everything is not so simple: the old paint does not possess adhesion (adhesion with an applied material), which means that no coating applied to the painted surface will not be durable. And if you also consider that bacteria and fungus have accumulated over the surface, and in the room it is planned to live with children or old people, then without removing the old paint it is definitely not to do.

How to remove the paint: the choice of method and tool

In the world of repair, there is no particular and universal way to remove old paint: the choice will depend on many factors:

• Which specifically the surface was painted (wood, concrete or plastered walls);
• Paint type - acrylic, oil, water-free or water-dispersion;
• Planned financial and temporary costs;
• Available tool (and growing hand-growing).

So, what kind of paint is to be deleted? If you do not take into account modern materials, for example, based on acrylic or latex, then most often have to deal with the following types of coatings:

• Paint based on vegetable oils or olifa (oil);
• Water-emulsion;
• Water-dispersion.

Depending on the type of paint and choose a method and tool. If the type of coating cannot be determined, it will have to experiment with different methods, to which it will take a lot of time.

How to remove the old paint oil

Different surfaces that have different properties are subject to coloring, most often this:

• Concrete base (walls or floors);
• Metal;
• Wooden surfaces;
• Plaster;
• Plasterboard.

Oil paint does not have any adhesion to any mixtures and glue, so it is recommended to be removed anyway. The most difficult to purify concrete bases from oil paint. But, in the presence of tools and skillful hands, everything is possible!

We will consider the following methods for removing old paint:

1. Mechanical is not the easiest, but more or less safe.
2. Thermal - it will take a special construction tool for him.
3. Chemical - the most unsafe in terms of chemicals applied.

What may be needed to remove old oil based paint from the base from concrete?

Perhaps it relates to the most budget and affordable for any way to clean the concrete surface from paint, but also to the most time consuming. The paintwork is scraped from the surface either with a spatula or with the help of another tool with an acute end (for example, an ax or chisel). To facilitate the task, small notches are made on the concrete surface, and then everything is wetted with water. When the concrete base is slightly splashing, you can proceed to scraping paint.

It is worth noting that since this method does not use any chemistry, it is the safest for health, however, to wear safety glasses and the respirator will still have to.

Mechanical removal of paint is perfect for small on the walls of the walls and for non-refined premises. But the processing of large surfaces take a lot of time, and it may be worth paying attention to another mechanical method - sandblasting with small abrasive. Suitable for old walls and wooden surfaces. The paintwork is knocked down with a jet of air and fine-grained sand (or soda). The method is not cheap, requires a professional approach and the presence of special equipment, so that our craftsmen applied rarely.

It is also often used by the Bulgarian with a special nozzle, which is also processed with paint surface. However, this method is the most dusty and dirty of all, and the effectiveness is controversial.

Removing oil paint using thermal exposure

For this method, you will need a special tool - a construction hairdryer, which, by the way, is not available in every home. The difference between the construction dryer from the usual is that the flow of blowing air is much stronger and hot. It is under the action of high temperature that the paint begins to "melt" and move away from the base. After softening, the paint can be scraped by the same spatula or scraper.

By the way, it is possible to remove the old paint with the help of a constructional hair dryer from wooden surfaces, for example, with old interior doors of the Soviet sample.

Another thermal method from Russian craftsmen: to cover the wall of the foil and "go through" a hot iron.

The thermal method of removing paint has its own "contraindications": it cannot be used in the case of the presence of elements that can melt (for example, plastic) or wiring. In addition, the sharp smell allocated when the oil paint is heated forces the use of these methods of well-ventilated areas.

Chemical way of removing old paint

The name of this removal method speaks by itself: the old coating is removed from the surface using a special chemical agent or purchased in the store or prepared independently.

Attention! This is the most unsafe for health a way to remove a paint coating, since all chemicals of poisonous and use them should only be used in a well-ventilated room and with personal protective equipment.

It should also be noted that this method is one of the most effective, but expensive, and the removed paint will have to be disposed of by a special way.

To remove old oil paint to the surface in several layers, a special means is applied using a brush or roller, and then removed with a spatula or scraper.

A tool for removing paint can be purchased in a construction store, but you can also use other, "home" methods:

1. Solution from water, lime and potassium carbonate. Mix 2 parts of the lime and 1/3 of a part of the calcined soda, dissolve them in a small amount of water so that there is a pasty consistency. Then, a similar solution is applied with a thick layer on the surface at least 12 hours, after which the softening paint is removed quite easily.
2. Handling wooden floor soda. This method is suitable only for the old wooden floor: wet the surface, pour a layer of soda calcined soda, cover the burlap and recycently mixed with water. Leave in this form for a day, during this time periodically wasting burlap. Then the swelling paint is removed by either a scraper or a spatula.
3. Surface treatment with liquid glass. The method is also not cheap: liquid glass is simply applied to the wall, and after drying it forms a film that is removed with the paint. But it is necessary to acquire such a tool in the store and removes it only one layer.

Whatever way you choose, do not forget about personal protective equipment: rubber gloves, protective suit, respirator (or gas mask), glasses.

Removal of waterfront paint

The water-emulsion is one of the few kinds of paint, which are perfectly washed off with water, of course, not without effort.

In order for the paint well "retired" from the wall, the surface is first wetted with water and left for 10 minutes. When the coating absorbs all moisture, the old water produce is easily removed with a metal spatula.

At first glance, it is difficult to determine that the wall is painted with water-emulsion paint, but it is worth spending a wet sponge on it, like traces of paint will say for themselves.

How to remove water-dispersion paint

The water-dispersive composition is more resistant to moisture, and, therefore, it is harder to rub off with ordinary water. But in this difficult case, there are three ways to remove water emulsion from the walls:

• With water and sponge;
• Mechanically;
• With the help of salary with newspapers.

With water and draft

This method cannot be attributed to effective, it all depends on the quality of the paint itself, and most of the manufacturers of paints and varnishes declares stability to wet cleaning. But, nevertheless, it is worth trying to twist the water-dispersion paint on the wall.

To do this, warm water is applied to the surface, after 10 minutes, the procedure is repeated. After the water is completely absorbed, you need to open all windows and doors to organize a good draft. By the way, you can use the fan by sending a forced jet of the air to the surface. The swollen paint can be removed either by means of a roller or with a brush.

Mechanical method and with the help of newspapers

One of the old but very effective ways to remove water-dispersion paint is the wamp of the wall with newspapers. After drying the glue, the newspaper is removed, often together with a layer of paint. And the poor places are easily processed with a spatula or sandpaper with a large grain.

The mechanical method is much more dusty and sometimes it turns out to be ineffective - this is the use of a grinder with a wide circle. However, this method is the most dirty and dusty and after literally minute work will have to wait another half an hour when the dust is falling. You can also clean the surface from old water-emulsion systems using a perforator with special abrasive nozzles.

How to remove acrylic paint?

Acrylic paint is a modern paint material based on acrylic, which is easily applied to the walls, dries quickly and practically does not smell. The paint is considered one of the modern and is removed easier than the oil or resistant water-dispersion paint. You can use coarse sandpaper or metal brush to remove acrylic paint. If the paint is good and persistent, then you can resort to the described methods for oil paint. However, if the painted surface will again be covered with acrylic paint, then it is not necessary to clean it: good adhesion acrylic paint with a similar one is one of the advantage of this decorative agent.

No matter what kind of removal of old paint you choose, remember the means of individual protection and do not work in poorly ventilated areas. Always follow the instructions specified on the packaging of the applied tool or tool.

Walls in many houses are covered with a thick layer of paint. In order for the new finish tightly on the basis, most often you have to remove the coating that has learned your time. So how to remove the old paint from the walls is not always simple and safe, it is worth studying all possible methods that will help facilitate this process and choose the optimal one.

Do I need to remove old paint

It requires the cleaning of the walls and the ceiling from the old paint depends on the state of the existing coating and further plans for its finishing.

When paint is removed:

• Under the stucco;
• Under the wallpaper;
• Under ceramic tile;
• If the coating does not hold and fall off pieces;
• If a large number of layers of paint and varnish coating are applied.

Walls can not be cleaned in cases if the coating is perfectly held, and the walls will be painted with the same type of paint. Also restored the base is not necessary if the walls are planned to be plasterboard.

To apply a new coating from the wall in most cases it is necessary to remove the old

What to take into account before starting work

Before cleaning the walls with some definite method, it is important to take into account the complexity of the work. The surface can be covered with different types of paints and have different degrees of absorption.

Paint can be acrylic, water olive and oil. The most difficult to remove the last one.

Types of foundations:

• Concrete;
• Wood;
• Brick;
• Plaster;
• Plasterboard.

It is easier to remove the old paint from the walls covered with a layer of plaster. The most difficult with a concrete base, for example, from the wall in the bathroom. Mechanical removal from drywall can cause damage.

Note! The more layers of finishing applied on the basis, the easier it is to remove it, and vice versa.

To choose the optimal cleaning option, you can try to scrape the coating from a small plot with a spatula and evaluate how it is separated from the base. If the paint is easy to succumb - then manual methods of cleaning will be suitable. If it is kept tightly - without chemistry or special tools can not do.

Some cleaning methods do not require financial investments, for others you need tools or reagents - this factor is also worth considering.

Preparation for the removal of old coating

Cleaning walls from the old finish will surely entail the formation of construction waste and dust, so it is necessary to think about the personal safety and protection of furniture in the room.

The floor and furnishings are needed to cover with polyethylene or paper to make it easier to clean after repair and do not spoil the upholstery of the furniture.

Together with the paint from the wall you can remove fragments of plaster, brick and concrete, so it is important to protect the skin from mechanical damage, a dense clothing will be suitable, which will close the whole body and thick gloves.

Special attention requires respiratory authorities. When using mechanical methods, dust particles will fall into lungs. With chemical - harmful evaporation. For these reasons, it is necessary to use a respirator and eye goggles.

Important! Any methods can be dangerous to health if not providing protection measures.

Wall cleaning methods from old paint

Options are not so much: mechanical, chemical and thermal. For the first, a large set of tools will be required: spatulas, scrapers, brushes, power tools with various nozzles. For the second, special reagents are needed. For the third - powerful construction hairdryer. What is the essence of these methods and how to clean with their help, read on.

Chemical

The essence of this method is to soften the old coating of chemicals and hang it with a spatula, a metal brush or scraper. There are two types of washes: alkaline and organic. They can be bought in a construction store or prepare on their own.

Benefits of the method:

• Rapid effects;
• Minimum of physical effort;
• High paint efficiency applied not more than two years ago;
• Effective in difficult situations, for example, such as paint removal from the concrete wall.

Disadvantages of deletion by chemicals:

• Most often solvents for washing toxic for mucous membranes and respiratory organs;
• Removed paint can not be disposed of with household waste, the more wash into the sewer;
• The unpleasant odor after working with reagents does not destroy for a long time;
• Low efficiency when working with a very old and multilayer coating, sometimes the procedure has to repeat several times;
• High price.

If this method was selected, it is important to clean through all the rules.

How to wash off the paint from the walls by chemical means: make a solution according to the instructions on the package, apply it to a surface with a wide brush or roller, to withstand about 10 minutes (time may vary, orient to the appearance of the coating, if it swallowed, then you can delete). Remove the trim with a spatula or brush with a metal pile. If necessary, repeat the procedure.

In addition to industrial funds, you can use their own preparation compositions. For example, make a thick mixture of water, 1200 g of negated lime and 400 g of calcined soda. The finished composition must be applied to the surface and leave for the impact of 12 hours. After that make the paint with a spatula.

Liquid glass can be used (it is aqueous alkaline solution of sodium silicates). The composition is applied to the wall and are waiting for its complete drying, while the mixture will be flawed from the wall independently together with paint and varnish coating. Perhaps the one-time procedure will not be enough.

Mechanical

The essence of this method of removing the old finish is to consider it to the base or give the coating a rough surface suitable for clutch with a future decorative coating. You can manually clean the paint: an ax, hammer and chisel, scraper, as well as using a special tool: perforator, grinder, electric drill.

Benefits of the method:

• Features high efficiency for coatings of any thickness and age;
• There is no smell;
• Not toxic;
• Does not require financial costs.

Disadvantages of mechanical cleaning:

• There remains a lot of construction garbage and dust;
• Noisy;
• Long time;
• Requires great physical efforts.

The hammer and the chisel will help in removing not only tiles, but also paints, but not in all cases

You can clear the scraper by the scraper only a multi-layer finish on an excavated wall. The paint should be easily peeling, usually this happens with a coating caused by many times for several years.

The ax is a more efficient Dedovsky tool to remove finishing. It is important to understand that as a result, the foundation will acquire deep irregularities. This surface is ideal for adhesion with tiled glue or plaster.

For other types of finishes, you will need alignment. If the paint is poorly separated, you can make a few notches with an ax, then moisten the wall with water and consider the coating when the base is soaked in moisture.

The hammer and the chisel are tools that allow you to remove any paint from the plastered surface. This method is not suitable for too dense bases: concrete, brick, wood. The process is very long. The wall as a result will acquire numerous excavations.

Significantly accelerating the process of mechanical cleaning will help special tools. But it is important to consider that the risk of getting bodily injuries during the work and significantly increases the amount of dust, therefore close attention should be paid to individual protection. Especially in the premises of small square, as it is much more dangerous to remove the paint from the walls in the bathroom or the toilet than in a spacious room.

Tools and nozzles for removing old paint from the walls:

• Bulgarian with a rigid wire brush or grinding circle. Creates a lot of dust, but it brings the finish with a uniform layer and the desired depth. With this tool, you can fully cover the coating, and give it a roughness to improve adhesion. When working it is possible to fire as a result of friction or spark. To reduce the amount of dust, you can apply the construction vacuum cleaner.
• Drill with a nozzle from chains. It only believes paint, leaving the layer of plaster in the preservation. The coating leaves small pieces. The formation of dust is at times less than when working with a grinder. In the process of the chain wears, when it remains three levels, they change them. The nozzle on the drill is a crucifier, has the same effect as Bulgarian. You can use and brick crown. It is suitable for removing the coating with dense concrete surfaces.
• Perforator with a nozzle in the form of a blade. This tool is capable of cleaning the wall not only from paint, but also from plaster. The speed of work is about 1 square meters per hour. The method is very noisy, but effective.

Important! The power tool creates a lot of noise - you can only work at certain hours and days of the week!

Sometimes removing the paint from the wall is mechanically impossible due to the brittleness of the surface or too thin coating layer, and the chemistry is unsafe. In such cases, it is necessary to look for alternative ways. For example, thermal, but it is far from being perfect.

Thermal

The essence of the method is to soften the finish by heating and consider it with a spatula or scraper. This method is suitable for wooden and plasterboard bases. On concrete and brick less efficient, since they are difficult to warm up to the desired temperature. For heating, a construction hairdryer is used (household does not fit) or iron and foil.

For a thermal method, a special construction hairdryer is used or ... foil and iron

Benefits:

• Cleaning does not create noise;
• There is no dust, only the garbage only large plates of old paint;
• Physical strength is not required;
• Suitable for surfaces that cannot be subjected to strong mechanical effects (window frames, door canvas).

Disadvantages of the method:

• When heated, toxic substances and caustic smell are released;
• Long;
• Requires a special tool;
• It is possible to ignite the paintwork;
• You can not use near electrical cables and plastic finishes.

Instructions, how to remove the old paint from the walls with a construction hairdryer: Send a jet of hot air to the painted area and keep before the bubbles appear, then remove the hair dryer and immediately remove the finish with the spatula. This work does not tolerate delay. Softened and newly dried paint can clutter even more with the base.

If there is no construction dryer, you can try to use the iron and foil sheet as a gasket. Foil must be applied to the wall, then for a few seconds to press it with a preheated iron and quickly clean the soft paint with a scraper or spatula.

There is not so many options how to remove old paint, they all have pros and cons. Preferred is still better as safe ways, especially if you do not have any attitude towards construction. Start testing the coating for strength from the simplest methods. For example, try to trim the finish with a spatula or an ax, if they did not give effect, try other ways.

Removing dried paint always directly depends on the composition of the coloring material, as well as from the type of the painted surface. Let's consider the simplest and most effective ways to clean the finished surfaces, their pros and cons, as well as safety equipment.

How to determine the cleaning method?

In Soviet times in bathrooms, kitchens and other rooms were a very popular phenomenon. Because of this, many of us and today are faced with the need to remove the old dried material. However, some real estate owners prefer not to get rid of the previous finish. Here everything directly depends on your future preferences. If you want to separate the walls with plasterboard, then the paint can be left untouched. Nevertheless, in most cases, to remove paint from the walls after all will have to, because colored walls do not have adhesion to plasters and various tiled adhesives.

Remove the old dried material can be different. The choice of the method affects several important factors. The first is the type of surface and the finishing work planned by you. The second is the main components of the paint applied earlier. The last factor is the tools that you have to work with.

Paints are several types. The most popular includes acrylic, water-emulsion and oil compositions. In practice, the most time and effort leaves for cleaning from the old paint on the ceiling coatings made of concrete. In such cases, you will need a maximum of time and patience so that you still find the appropriate cleaning method. In addition to concrete, the paint is applied to the tree, metal and plasterboard.

What tools need to be prepared for work?

Old dry material is removed from the surfaces using certain tools. Their list may differ slightly depending on the method you use. Nevertheless, before cleaning the walls from dried paint, prepare in advance:

• wide chisel, spatula or iron scraper;
• chemical cleaning agent;
• ax for notches;
• construction hairdryer.

If pieces of paint remained on the wall, which were very grabbed with the surface, then remove them with the help of an electric drill equipped with a special nozzle. Often, residents use a bulgarian with a wide nozzle, if you need to clean the wall from large pieces of material.

In any case, you need water to work, which will help soften the old coloring composition. From personal protection tools, use glasses, gloves, respirator and a suit of dense tissue.

Methods for removing oil compositions

As a rule, the greatest difficulties begin when you have to remove the old oil paint from the walls and the ceiling. Suitable for this cleaning methods exist only three: chemical, mechanical and thermal.

One of the most effective methods for cleaning the surface from oil compositions is considered chemical. The essence of this method is to prepare a specialist strictly according to its instructions. After that, the composition is applied to the walls. Next, the surface is left for a while so that it is mocked. After 30 minutes, the paint will become softer, and it will be easier to remove it from the surface. Despite the fact that this is the only way to quickly get rid of the old finish, it has one big minus - the cleaning agent has a very unpleasant smell, something resembling ammonia. It is very difficult to get rid of sinuals, and for this you have to leave in the room draft for several weeks. In addition, this method does not guarantee complete cleaning of the walls from the first time. Because of this, masters have to apply chemicals in several stages and after everyone to scrape the falling paint.

If you chose this method, then do not forget to use individual protective equipment. It is necessary to work with chemicals only in a constantly ventilated room in the respirator, glasses and gloves.

In addition to the use of chemicals for cleaning, the following methods will also be suitable. To remove the old oil paint from the walls, prepare a mixture of lime and potassium carbonate. To do this, in five liters of water, add 1 kg of negated lime and 300 g of potassium carbonate. After thorough mixing, apply a mixture with a uniform layer on the wall and leave the coating for 12 hours. After that, remove the falling pieces of the material. If there is a need to re-apply the mixture layer and wait another 6 hours.

To get rid of oil paint on the floor of the boards, weanly moisten them with water and pour the coating with soda. After that, the floor is covered with dense burlap and leaves for a day. In the raw materials, the paint will quickly swell and will easily go away from the board.

Often, specialists are used to remove old oil paint. For this, the surface is uniformly lubricated and left for a couple of hours. In the future, the dried glass will be easily flapped from the surface with the paint.

What is the essence of the thermal cleaning method?

Remove the frozen oil paint from the walls can also be used by the construction dryer. For this, the old finish is heated by the device and immediately believes from the surface. In case there is no hair dryer at hand, you can take a piece of foil, apply it to the wall, heat the iron and remove the paint.

It is important to remember that this method cannot be applied in those parts of the wall where electrical wiring is inside it. Sometimes ignorance of this leads to the cliff of the wires in the wall, is not so easy. Experts also do not advise using a construction hairdryer or iron in places where on the opposite surface of the wall is a decoration from decorative plastic panels.

However, this method is perfect in a situation where the wall must be cleaned without shocking and vibration. The thermal method will help remove the paint with glazed doors, window frames. The extradition of the heating paint of caustic toxic substances is considered a large disadvantage of this method, due to which an indous smell appears in the apartment. So that it does not happen to trouble, be sure to wear a respirator.

Mechanical removal of old finish

Remove the oil paint from the prepared walls can be both mechanically. He finds its use quite often, because not many want to breathe toxic evaporation.

The oldest way of mechanical cleaning of the walls is the apparel of the surface with a small ax. The process is quite laborious and long, but, at the same time, also the safest. In addition to the toporist, water will need water.

To begin with, it is necessary to make notches on the surface, and then spray the surface with water from the spray. 10 minutes later you can start cleaning the wall. Very much depends on the correctly selected tilt tool. Therefore, in order to cope faster, you will have to experiment a little with the toporist.

Very often, the mechanical method is used if in the future the housing owner has planned to carry out the wall cladding with ceramic tiles, because only this finishing material has a good clutch with an uneven damaged surface.

Mechanized methods of mechanical removal of paint

There are several tools that will quickly remove pieces of old finish. Many experts advise newcomers to use a grinder with a wide range. Do not forget that as a result there will be a lot of dust, therefore, worked on just a minute, you will have to rest for 15 minutes. In order not to spend time, you can purchase a modern grinder equipped with a built-in vacuum cleaner.

Often, the removal of old dried paint from the walls is carried out with a drill. To do this, the chain is used as nozzle. This method is considered very cheap and efficient and used to work with wooden, concrete and metal surfaces.

For operation, two configuration chains are used. In the first case, experts use the so-called "pea". It consists of 13 identical units, the thickness of each of which is 5 mm. The center of the nozzle is 1 link, which is attached 6 links on each of the parties. If during operation one link disappears, then you need to remove one link on the other hand. It is possible to work until at least 3 links on each of the parties.

The removal of dried paint from the walls is also performed using a brick crown. This nozzle quickly destroys the old finish and helps when working in the most running cases.

How to get rid of acrylic paint?

To remove acrylic paint from the walls and the ceiling, use the rigid metal brush or sandpaper. To do this, you will have to spend a lot of time and effort, plus to this, no one can guarantee the complete removal of the old coloring composition.

Despite this, the best cleaning method has not yet come up with. In this regard, many real estate owners perform a new finish using the same acrylic paint. In the process of work, the new composition perfectly falls on the old one.

Significant methods that are categorically not suitable for the removal of acrylic paints. The thermal method is highly dangerous, since any heating of the material can lead to unpredictable consequences. A chemical method of cleaning is also not suitable for this purpose, because the components of acrylic paint will quickly come into effects with toxic substances of chemical cleaners.

When the repair, many wonder - how to remove the old paint from the walls, while without damaging the walls themselves, for example, in the bathroom? And also how can it be done easily and quickly, how to remove the water-emulsion, and how to remove oil paint from the walls? It is logical that it makes no sense to glue new wallpapers right on the painted surface: not only that it is a priori uneven, so also bright dark colors of paints can shine through thin paper of light tones. And, of course, you will have to tinker with the old paint if it is planned to repaint the room.

In total, in modern to create interior solutions, there are four main types of paints: oil, water-emulsion, acrylic and enamel. Additionally, the textured patterns are distinguished, spreading with a variety of effects or in their composition of inclusion from other materials, which create irregularities. Such paint, by the way, remove from the walls will be most problematic. Also allocate types of paints by applying - for example, aerosol samples.

So, the types of paints used in the interior decoration, including the bathroom, are fine from samples that are quite difficult to remove, to easily removed:

1. textured samples of any type and composition;
2. oil;
3. water-emulsion;
4. acrylic.

How to remove the old oil paint from the wall?

Oil paint, especially used for external paintwork, is very difficult to belong to the surface. In the past, when repaired, for example, the bathroom even preferred simply overlap the old layer of new. It is logical that this approach is not in all cases will be appropriate, and sometimes it is necessary to completely remove the old layer.

Before removing the oil paint, it is worth placing several pelvis with warm salted water. So you can avoid the spread of an unpleasant smell of paint of this type. The same advice works if a new layer is applied.

On a small scale, the oil paint is easy to remove, using the following substances: "White spirit", Pinen and other solvents, will be less effective to be turpentine and ammonia alcohol. All the above compounds are volatile and extremely odorous, and therefore will have to thoroughly close the neighboring rooms, as well as work in the respirator. The solvent will need a lot, and the result will be meager, therefore this method can be left exclusively for those cases where the painted surface is very small, literally point, and not on all walls of the bathroom.

Therefore, today apply other ways:

1. mechanical;
2. thermal;
3. chemical - with professional reagents.

The simplest way to destroy the old oil paint on the walls in the bathroom is the following: the construction dryer heats a small area, and then it is cleaned by a spatula manually. In this case, the paint will have to be deleted, applying significant physical efforts. In some cases, it may also need a small hatch for chip layer. Work will have to work in gloves, overalls and, best of all, in special glasses. You should take care of the removal of wiring on the walls and rest of the neighbors. The condition of the walls of the bathroom after such a dismantling paint from the wall leaves much to be desired and requires alignment.

other methods

A more civilized way is the use of a small building grinder. Aligning walls after such intervention in the interior will be minimal. In addition, in the bathroom, you can immediately start the installation of tiles or PVC panels. The method is noisy, also requiring special equipment and a certain skill.

In addition, an electric drill is often used as a crushing oil surface of the tool. Noise can not be avoided, errors, too - if before this business did not have a drill. Professionals advise to use special nozzles to dismantle. Well established a nozzle "Chains". With minimal damage to the walls, the sample will allow you to quickly get rid of unnecessary old paint using the three chains segments of 4-5 units. You can also arm a special crown used to work on a brick surface.

In general, the modern arsenal of methods of getting rid of walls from obsistent paint includes including low-prolonged methods - with the help of sweater. For example, a household iron heats the paint area through foil, and then also use the spatula.

Chemistry will help us

In order to remove with the walls of the bathroom with a bothery paint with a mechanical way, it is not necessary to know its composition. Drill and Bulgarian will be perfectly removed including the water-making paint. It is even easier to deal with acrylic samples - special solvents for this type of paints will help to quickly and painlessly get rid of the colorful layer. In order to take advantage of the chemical method, it is necessary to clearly distinguish the type of paint: the water-emulsion, acrylic or oil, is likely to be removed from each type of reagent.

The scheme of the chemical method is as follows: The special reagent is applied to the paint, leave the room and after some time there is no lack of raising an unnecessary layer in the same spatula. The difference from the thermal method, in which a construction hairdryer or even iron is used for the walls, at first glance, minimally. However, in fact, the chemical method will allow to spend less effort, but they will have to spend on the reagents. In addition, they will also have to search for shopping, as well as to further buy personal protective equipment, including special glasses and respirator. Using ready-made reagents, remove the layer from the walls will not be difficult.

Advantages and disadvantages of each method

Pros and disadvantages There are absolutely every way of dismantling the old paint and varnish coating. Absolutely in each case, tenants will have to leave the room for a while. With mechanical removal of paint from walls in the air, unsafe to health can be formed, besides having a rather sharp smell. In addition, you will have to warn the neighbors about the upcoming noise. A relatively silent way remains to remove the paint with a thermometer with a spatula, but no one is indifferent from unsafe dust and exhaustive labor. The chemical method, at first glance, it seems simple - just put the reagent and wait for the brush and wait, and then easily remove the residues of the paint. However, the contact of the skin even a small amount of a special reagent may cause a burn and an allergic reaction, and careless inhalation can lead to more deposits. This category of funds is so toxic that is not subject to disposal in the sewage system of a residential building, which also creates additional difficulties and concerns.

There is always an alternative to the removal of paint - this decision to leave it. The unsightly old layer is easily covered with PVC panels, wooden clapboard, wood massif and other types of coatings. In some cases, it is worth choosing a primer that will fall on top of the old colorful layer and serves as a clutch for a new paint coating absolutely any color and composition, and the old will not shine.

It is also worth taking care to facilitate your own work. With a mechanical method, it is highly recommended to use a building vacuum cleaner, sucking harmful dust. In all other cases, thick special gloves resistant to reagents, special protective suit, glasses and respirator will be helped. When using a chemical method, it is categorically not recommended for the use of a cottage-marlevic bandage instead of a special respirator. Secondly, it should be remembered that the universal magical way - the composition and simply rub the surface from the old paint - they still do not yet exist, and whatever means of removing the paint-layer you have chosen, you will have to work your hands to transform the interior of the bathroom or other room.
