Cleaning doors from old paint. Doors under painting: We make training and paints

If you started repair in the house with your own hands, then definitely pay attention to the state of doors, windows and gender. Wooden doors have many advantages over modern products. They differ in both quality and convenience, and will also be able to serve you for a very long time. If you have a good wooden door, but the paint came up on it and cracked, do not hurry to throw it away, but try to update it. To do this, you need to know how to remove the old paint with doors.

Features

Before painting the canvas, you need to remove all the layers of the old paint and varnish coating completely. Otherwise, it will look not only not aesthetic, but not to close. There are several options for removing outdated paint from a wooden surface. The most common ways:

• Chemical;
• Mechanical;
• Thermal.

Chemical

The chemical method is considered the fastest. There are different washes for paints. In their composition necessarily contain solvents for softening of paints. This makes it possible to remove it with a simple construction spatula (metallic).

Immediately prepare all the materials and tools that will be needed for you to work:

• chemical to remove the coating;
• brushes;
• solvent;
• putty knife;
• protective glasses;
• gloves.

Now proceed to the process, guided by video:

1. First remove the door from the loops, and also remove all the locks as shown in the photo. Work is better to perform in the utility room or in a separate room;
2. With the help of a tassel, apply a wash on the old cloth;
3. Let it brew and start rubbing until the paint starts to peel;
4. Clear paint remove the spatula, and the remains can be removed by sandpaper.

Note that there are special chemical washes for different types of paints. If you take a non-solvent, there will be no effect.

In addition, all chemical compositions are toxic, so it is necessary to work in gloves and goggles in the open air or ventilated rooms.

For the removal of old paint from the wooden canvas, a special chemical paste is also used, which is prepared from caustic soda and tolkna. You can prepare such a composition:

1. Caustic soda is completely dissolved in water;
2. Then add oatmeal and stir until the pasty mixture is turned out, as shown in the photo.

This composition is usually used for doors with a complex form. Also such a paste is better to apply when removing a multilayer coating and in hard-to-reach places. For a better effect, the composition must be applied on the canvas with a thick layer. After the paint starts to be bubble, remove the paste with a scraper together with an old coating, and then wash the surface using water underground. With this chemical composition you need to work carefully, so as not to burn your skin.

Mechanical

To work mechanically need to cook:

• scraper;
• chisel;
• grinding machine or "Bulgarian".

Of course, this method of work is long, and besides, it is possible to be injured. However, sometimes without knives and other acute items it is difficult to clean the product from paint in hard-to-reach places.

The mechanized method is to apply grinding machine. But it can be effective only if the door is covered with only one paint layer. If the coating is multilayer, then it is better to use "Bulgarian" with craft brushes, as shown in the photo.

Thermal

The construction hairdryer is an indispensable tool with thermal processing of doors covered with old paint. Modern hair dryers have a heating control, with which you can soften the paintwork on a wooden surface, and then clean the knife as shown in the photo.

If the door has glass, it is better to remove them. The air temperature that comes from the hair dryer is equal to 600 degrees and glass can simply crack.

If you are going to paint a restored cloth with your own hands, it will not cost you much difficulty. One can only advise trial work first with the "invalid" side of the door. Then on the other hand you will not make possible errors.

Let's summarize

Wooden doors are considered the most durable, and after restoration you can not squeeze five years. Interior doors will last even longer, since indoors are installed and are not subjected to various weather effects.

If you have a desire to update, give freshness in the process of arranging or repairing the house, or completely change the appearance of good-quality items from wood - doors, gender, windowsill, frames, platforms, cabinets, tables or chairs, then in this case there is an urgent need for first A case to remove the old paint from the tree, that is, to prepare the surface for all subsequent works.

And if in the case of the new surface, the situation is quite simple: it needs to be seized, and then climb, then the old wooden surface will require much longer time and effort to bring it into the proper look. The case is also complicated by the fact that the tree is a relatively soft material, and when the paint is removed from it there is a risk of damage to its surface.

Is there any need to remove paint from a wooden surface? This is perhaps the first question you ask yourself, deciding for some restoration work. Indeed, in some cases it really does not make sense to remove the old paint from the surface, and it is quite possible to apply a new layer of paint on top of the old.

In this case, we should look closely to the treated surface: if the layer of old paint is thin, the paint does not lag behind the surface and there are no cracks on it, it will quite be enough minimal processing of emery paper, after which it will be possible to re-stain.

• the previous layer of paint is too thick;
• the surface has already been painted repeatedly;
• there are cracks on the old paint layer;
• the former layer is bubble and lags behind;
• you are going to use another kind of paintwork, different from the previous one.

How to remove the old paint from the tree

There are three main ways to remove the old paint from the door or other surface of the tree:

1. Mechanical
2. Temperature
3. Chemical
   

Mechanical method for removing the old layer of paint from the surface of the tree

This method is the mechanical effect on the previously painted surface. This is the first way that is trying to apply to clean the surface of the door, floor, windowsill or any object of wood furniture from the old paint. In this case, it simply scraps using the appropriate tools:

• spatula;
• metal brush;
• emery paper;
• chisels;
• scraper.

In addition to simple hand tools that require significant physical effort, you may need power tools more serious: electric drill with a special nozzle for grinding and cleaning, a grinding machine or a bollard with a disk for grinding and cleaning.

The mechanical method of removing the old paint is justified, if the paint layer is already very old, and the paint is easily peeled from the surface. It is also nice to clean the old paint with a mechanical way with smooth surfaces, or a small area of \u200b\u200ba small area, for example, window frames.

However, if we are talking about uneven ornamental surfaces, such as twisted, carved and curved elements on doors, furniture or platbands, simple mechanical removal will be too complex, time consuming and ineffective. Another negative moment of grinding is the impossibility of removing paint entirely, since it usually only makes the paint layer thinner, and in hard-to-reach places, paint, as a rule, remains.

Temperature Removal Temperature Wood Removal Method

An effective means for removing the old paint-layer with their own hands is its heating, followed by removing peeling paint with a spatula.

How to remove the old paint with a construction dryer? To do this, you need to direct the jet of hot air from the hair dryer to the machined paint surface. From the impact on it heat, the paint softened and begins to swell, after which it is removed with a spatula, a scraper or a chisel. If there are recesses on the surface, the paint can be removed by a triangular spatula. For the absence of such, you can use the shaving machine.

But remember that this process requires accuracy and caution, because with an imperative handling of the hairdryer and a spatula, you can hurt or damage the wooden surface. It should also be borne in mind that with the help of a hair dryer it is difficult to remove the oil paint, because it, unlike other types of paints, does not penetrate when it is heated, but melted, turning into a fatty soft substance that is difficult to remove the spatula.

How to remove old paint with a tree with a chemical way

The tool for cleaning the old paint from the door, frame, platbands or furniture can be made by either purchased ready. The home product in this case is a solution of caustic soda. This method requires great caution and the corresponding protection of open areas of the body, that is, it is necessary to wear thick rubber gloves and unnecessary clothing. Next you need to pour into an unnecessary container a solution of caustic soda and apply it to a brush to the painted surface. Continue applying until the old paint starts to be covered with bubbles. After that, you need to consider the paint with a spatula, a scraper or chisel, and act on the treated surface any degreasing agent, or at least wipe it with water.

It is much easier for the removal of old paint from wooden items, to purchase a ready-made chemical agent for a certain kind of paint in combination with a tree surface. It is very important when they are used to pay due attention to the protection of the skin, eyes and respiratory tract: the eyes protect the glasses or mask, hands - gloves, and unable to open the window at work.

If you cannot determine which paint it was used in this case for staining, for example, doors, you can choose a universal chemical for all kinds of paint. The selected solvent is also applied to the surface with a brush, roller or collapse, and after 10-15 minutes, the paint is easily removed by a spatula or even a rag, moistened kerosene or water.

Objects with age have a special charm. If you have an old wooden door, paint has shuffled on it, it's not difficult to give her a new life at all. It would seem why to mess around, if you can easily buy a new one: a rich assortment is offered in the shops of finishing and building goods. But is it worth it to change the solid wooden door to a modern product from thin MDF panels, hollow inside and trimmed with laminated coating, even if "Milan Walnut"? The existing product can be renovated with their own hands. To begin with, you will need to remove the paint from the wooden door.

Remove the old paint

Why repair the door?

Before viewing ways to remove paint with doors and choose the most appropriate option, let's think about it, and why waste time and strength.

1. Old wooden doors have good quality. They are made of array, very often the material for the manufacture served as an oak, even if the sash is painted.
2. Non-standard vintage door canvases. In old apartments, old doors are often standing, high, bivalve, viper. There are no such store, and the manufacturer will cost expensive.
3. The door is beautiful. If you are lucky - and you are the owner of a richly decorated carvings of the doorway, throw it on the garbage will be blasphemy.
4. Art object. If you are a creative person who can create a work of decorative and applied art, then a wooden sash is a great field for creativity.

From the above items it is clear that there are plenty of reasons for restoration and repair, and after all, you may have your own.

Materials

Theoretically, there are three ways to get rid of old paint:

• Thermal. The thermal method is based on heating the old paint to softening.
• Mechanical. The coating is removed using various scrapers, sandpaper. You can work in manual or using the power tool.
• Chemical. The paint is treated with chemicals, softened and removed.

In theory, everything is simple, but in practice, most often it is necessary to apply all three methods, because the chemistry dissolves not all types of paint coatings, heating fails to remove the layer in the recesses, and the mechanical method, even with the help of the power tool, is an extremely time consuming and dusty process. Therefore, you should not rely on some one option. Better stocking as much as much as possible devices and means.

To implement a plan to update the doors, you will need to stock up with some devices and patience, because it is likely to quickly remove the old paint with a wooden door, even looking at the video detailed instructions, it will not work.

Instruments

Construction hairdryer - an indispensable thing for removing old paint. It looks and functions almost like the usual hair drying. But the air temperature produces from 100 to 600 ° C. Therefore, contact him neatly not to get burns, and in no case use instead of the hairdresser's hair dryer. And on the contrary: if there is no construction dryer, then try to use the usual, for laying hair, it is not worth it. Results will not achieve.

In addition to the hair dryer, other thermal processing methods can be used: a soldering lamp or gas burner. These tools require special caution in circulation. You can easily overlay the plot, and damage not only the paint, but also the tree itself. In addition, these devices have an open fire, therefore, comply with the safety regulations. Even for heating the coating, an infrared lamp is used.

The cycle is a scraper having a metal blade and a handle. If you failed to get a special scraper, a spatula is suitable, or any other similar tool.

We need sandpaper with different grain. In addition to paper, special abrasive sponges are very comfortable, especially if there are reliefs on the surface, for example, thread. Very well, if your disposal has a grinding machine - use it significantly speeds up the process.

It's time to repair, and you concluded that old doors require updates. You are not going to buy and install new. To start the restoration, you will need to remove the old paint.

Such an operation is performed in several ways. But in any case, you have to remove the door with the loops. It is advisable to work on the street. But if there is no possibility, it is placed in the middle of the room, substituting the supports. Before cleaning the door from the old coating, you need to free it from the accessories, dismantle the loops, clean it from dirt.

Cleaning methods

There are several ways. Consider them in order.

Thermal method

It is usually used in the case of a small amount of cracks when the paint is firmly held.

To start cleaning it, you will have to get a pre-acquisition by an industrial hairdryer. Cleaned material when heated begins to bubble.

To clean the door, the coating is removed with a sharp spatula. You need to handle the hairdryer carefully to accidentally damage it!

Thermal method technology is simple, but this method is not suitable. This method can be cleaned old layer only if the base is wood. Plastic from heating can begin to deform.

Another disadvantage of the thermal method is the allocation of poisonous vapor. Therefore, it is recommended to do this on the street. In extreme cases, you need to open the windows and put on the respirator.

Thermal method

Mechanical method

Many know about this method of cleaning. You will need:

• spatulas;
• bulgarian;
• wire brush;
• flatSheliform machine.

Unfortunately, sandpaper will quickly determine the typewriter. Therefore, it is rarely used to remove the old coating on extensive areas.

First processed by a grinder. Then the paint is cleaned with a metal brush. The residues are watched by spatulas. Such a technology is characterized by consideration. Without the use of physical strength, it will not be possible to clean the old coating.

Important! When the paint layer is considered mechanically, it is accompanied by a large amount of dust. The operation must be taken carefully so that the basis does not receive damage.

Mechanical method

Chemical method

To remove the paint, you can use chemical solutions, they will make the layers softer, and they will easily wash. For this use:

• solvents;
• acids;
• alkali;
• special mixtures.

The solvent is applied to the door. Then you need to wait until the coating becomes softer. If the door is painted by several layers, it may be necessary to use the solvent composition several times.

The peeling layers are written by a spatula. Sometimes they dissolve completely, it will remain only rinse.

Important! Solvents are toxic, so you can only flush the paint in such a way on the street. It dissolves quickly, but the chemical smell will hold on for a very long time.

Removal of paint

How to wash off the paint from the metal canvas?

The wooden door can be periodically tying, but metal require another approach. They are all the time exposed to atmospheric influences. To update them, you need to clean the old layer. For this, the Bulgarian or drill is used, equipped with special nozzles.

Before starting processing, the door is removed from the loops and dismantle the fittings. It is advisable to perform work on the street. The coating can be removed by the most different tools and means:

• kerosene;
• emery paper;
• spatula;
• grinding machine.

Just do not think that such work will not require any effort. Even when very strong reagents are used to remove the paint, you have to make some effort.

It will not be able to clear one spatula, it will take a rigid nozzle or a good solvent. Working only with one tool, you can apply scratches on a smooth metal surface. This defect is subsequently impossible to hide even under the thick layer of paint.

Steel is treated with grinding machine. Of course, you can do it and sandpaper, but the speed of such work leaves much to be desired.

With old layers, the grinding machine easily copes, but only if the nozzles are correctly selected. Usually work is conducted by the middle spray head. The speed of rotation of the head must be minimal. Work should be done carefully to accidentally damage the door.

Properly selected nozzle helps to perform work quickly. The head must be constantly cleaning - it is quickly clogged with garbage particles. The effectability of work depends on the cleanliness of the nozzle.

After any way of removal, it is necessary to take the surface to achieve smoothness. If cracks are detected on the canvas, closed with putty. Before starting to apply paint, the surface is ground. When the ground dries well, you can start to engage in paintwork.

Cleaning

How to clean the door from water-emulsion?

How can I wash the water-emulsion? Today there are a lot of funds on the market, which help to wash off the surface of different coatings. To cope with this material, you can take advantage of the most popular means.

Washing "Manor"

Released by Russian manufacturers. Suitable for working with different surfaces:

• tree;
• concrete;
• metal.

Washing does not contain in harmful aggressive substances, so completely harmless to wood. Since the structure is gel, it is easy to handle the surface. When it dries, the coating begins to settle.

Work technique:

1. tassel to the surface of the canvas to apply;
2. wait 20 minutes;
3. spatula Clean the lagging layer;
4. rinse the door with warm water.

Tools for washes

"SET BOYA SOKUCU"

Special bow designed to work with water-emulsion.

Application technology:

• surface lubricate;
• wait 10 minutes;
• raising coating to clean the spatula;
• if immediately failed to wash everything, the procedure is repeated.

After removing the water-produce with a coaming solution, the surface is wiping with a nitrocellulose solvent and then washed with clean water.

How to wash off the oil paint?

To remove such a coating from the metal cloth, you need to follow the following technological sequence:

• 1.5 kg of oversized lime is divorced in water until the creamy mass is obtained.
• it covers the door and leaves for 12 hours.
• washed off the old layer.

Bleaching powder

To wash off the oil coating from a wooden floor, you need to moisten the surface with water and pour out the soda calcined. The door to cover a wet burlap. She should not dry, so it must be watered every hour. The next day the layer is easy to fly.

Important! Removal by chemical means requires mandatory safety of safety. Rubber gloves should be put on the hands, the eyes are closed with special glasses. Easy toxic evaporation will protect a special bandage. The chemical solution that fell on the body should be immediately washed with water.

As already mentioned above, clean the surface from the coating can be different paths. It all depends on the conditions and capabilities. To advise something particularly difficult, because each owner has its own approach to this issue.

Comparison of the removal efficiency using a hair dryer and a special tool for cleaning is shown in the video presented.

Wooden doors bring a special charm to the interior, but only if they look decent, and the paint is applied neatly.

Cracks on paintwork, faded shade and losing paint on the doors, are able to spoil all the impression of the room.

There is a need to remove the old paint. For this, proven chemical, thermal and mechanical methods are taken into service.

For details on how to remove the old with a wooden door, we will tell in the article.

Choosing a way to remove old paint, a question may arise, whether it is necessary to delete it at all? The answer to this question and the choice of the coating removal method depends on the following factors:

• type of door surface;
• coating condition;
• type of paint used;
• coating strength with wood;
• thickness and number of layers.

The most harder will remove the laying of a paintwork, which has a good grip with the material, and the door itself with a complex surface relief and a mass of decorative elements.

If the door is designed for subsequent painting, then depending on the state of the coating, you can do sweep by sandpaper. This is possible when the paint was applied neatly into one layer and does not contain detachals and chips. The old coating is simply processed by sandpaper, and you can apply a new layer.

Old paint layers, which, under the action of atmospheric influences and time, have significant defects (chips, cracks, bloating), have to be removed. It is also necessary to remove a too thick layer of paintwork, which has frozen drips and other results of non-accurant door processing in the past.

It happens that the new door paint is incompatible with the old one. This is also a reason to completely remove the paint with wooden doors.

Preparatory work

Pre-training doors requires purification from dust and dirt. Also it is necessary to consider the swollen layers.defined from the foundation. If one of the parties in the future will be hidden, for example, by the upholstery of the dermatitin, the paint can be carefully not removed - just consider the detachment.

Deciding with the character and scope of work, you should choose tools for removing the paintwork.

Be sure to:

• rag;
• putty knife;
• individual protective equipment (respirator, special glasses, gloves).

For a chemical method, we will need reagents, a bucket with water, a tassel for applying a special composition. Mechanical and thermal method will require the presence of a special tool (grinding device, drill with nozzles, industrial hair dryers).

How to remove at home?

To remove old paint with wooden doors one of three ways is used:

1. Mechanical impact.
2. The use of chemical reagents.
3. Exposure to high temperatures.

Each option has its own strengths and weaknesses. Depending on the specific situation, a suitable method is selected, the appropriate tool and drugs.

Thermal methods

The thermal method of cleaning the wooden door from paint involves the use of industrial hair dryer and spatula.

Order of work:

1. Turn on the hair dryer in the power grid.
2. Direct the stream of hot air to the door section.
3. When heating, the paint will begin to swell and fall behind, and it will be easier to consider the spatula.
4. The processing process is repeated in the following zone.

After the entire door is processed, you need to modify the missed fragments. The surface is impeded by sandpaper.

If there is no industrial hair dryer, you can use the iron, pre-laying between the sole device and the foil door.

The advantages of the method:

• environmental friendliness;
• not needed extensive experience.

Disadvantages:

• it is necessary to apply a special tool;
• it is not always possible to use on complex surfaces;
• there is a possibility of damage to the tree with incorrect setting of temperature regime;
• release may be required.

How to clean the surface with a mechanical way?

A mechanical method involves removing the paint layer using tools: from a conventional spatula to a drill with nozzles and other special equipment. The use of an electrical tool speeds up the process, but may not cope with complex places.

Method disadvantages:

• dust formation;
• high probability of physical surface damage;
• need a tool;
• the need to apply protection tools.

Advantages:

• environmental friendliness;
• the presence of a good tool speeds up the process.

As a suitable tool for removing paint coating, you can use:

Removing a multilayer coating with the use of only emery paper or a spatula is time consuming and inefficient.

The best solution solution is the choice of a chemical method or the use of power tools.

How to rain chemicals?

Washing in a chemical method is carried out using solvents. The technology is based on the destruction of chemicals of the structure of the dye itself:

1. The solution is applied to the surface with a brush.
2. Withstand the desired time, which depends on the composition and type of paint.
3. Acting a spatula or scraper, coverage swollen under the influence of reagents.
4. Choose paint residues.

If the inspection instructions state that the surface needs additional wi-alcohol ratio or other solvent, it must be done.

The advantages of the method:

• the speed of the chemical composition;
• simplicity;
• no appropriate application is required;
• no special skills are required.

Disadvantages:

• toxicity of chemicals;
• an allergic reaction is possible;
• mandatory availability of personal protective equipment;
• the need to organize good ventilation in the process of applying funds;
• caustic odor
• solvents require special disposal.

Despite its high efficiency, the use of chemicals often requires surface finalization by mechanical manner.

Before using the solvent, it is important to clarify whether it is suitable for a specific type of paint, and whether the state of wood allows this method of cleaning.

Selection of reagent must take into account the tree breed and material condition. Digging wood may not withstand intensive chemical impact.

How not to damage the door leaf?

The wooden surface has a characteristic texture, is distinguished by susceptibility to hard mechanical exposure.

When working with natural material, such moments should be taken into account:

In addition to refreshing paint, attention should be paid to the condition of the fittings. If necessary, replace or renovate elements from metal.

Cleaning Tips:

1. Works must be carried out using personal protective equipment.
2. Removable parts of wooden fittings, such as door handles, convenient to process separately.
3. If the door is removed, then it is desirable to remove it before cleaning and putting horizontally - it will be more convenient to carry out work.
4. For heat treatment it is impossible to use open fire - only hot air.
5. After cleaning, the defects of the wooden surface, to the coating of the new paint, should be eliminated - grinding, putty.
6. Before the new painting, the tree should be projected.
7. The use of stacks for paint and sanding can be recommended only with a thin layer of wood coating.
8. Grinding work on the tree with electric tool is recommended on the street. This will reduce the likelihood of touching the working part of the equipment a foreign object.
9. When used for cleaning chemicals, you should not use the plastic packaging - the solvent can "Dange".

A hurry when removing paint is inappropriate, as it can lead to damage to wood and injury.
