Useful tips on how to remove paint from wooden doors and not ruin the surface. How to remove paint from doors - make new out of old. How to make new doors out of old ones How to remove paint from a wooden door

The refurbishment is nearing completion, the finances allocated to renovate the home have run out, and some of the old surfaces do not harmonize with the new finishes. We have to update by improvised methods and make new from the old. The question arises - how to remove the paint from the door? There are several ways, but each has its own difficulties, and the whole process is quite laborious. But nothing is impossible for a home master equipped with a tool and knowledge of the simplest technologies.

Why remove old paint from a wooden or metal door surface?

High-quality painting is impossible on an unprepared surface, and the old painting was often applied to the doors in several layers, with bumps and smudges. And no matter how high-quality the new enamel is, the end result leaves much to be desired.

It is also important to recall what kind of reaction occurs between the old and new paint. It is not always possible to say with complete certainty what type of solvent or base was applied the last time. And when painting is done with a new composition, it reacts with the old layer. As a result - bald spots, cracking, curdling and other troubles. And then it becomes clear that it would be better to remove the paint from the old door.

With the next tinting of the base with a different color, sloppy strokes or a non-uniform color are often obtained, especially if a lighter paint is applied to a dark surface. If the paint is rare, then any other color is guessed under the new layer.

Multi-layer painting has another drawback - the doors close worse and worse each time, as new layers build up on the ends. It is not necessary to remove the upper and lower end of the door leaf, where the layer of old paint is strong enough, especially since these areas are not visible. In such places, grinding is sufficient if the type of paint matches the new one. All exfoliated areas and places with cracks require careful preparation of the door for renovation.

It is sometimes necessary to remove the paint partially, namely from the ends or only from one side of the doors, upholstered with leatherette on the outside. But still, it is a laborious process, and for an excellent result, you will need to make a lot of effort. The easiest way is to use a wood paint stripper, and a metal door is prepared for repainting a little differently.

Chemicals for effective paint removal from doors

The chemical method of removing paint is quite effective, the easiest way is to buy a special liquid in a building supermarket. However, this base (thinner) must be suitable for your type of wood or metal paint. On oil paint of a wooden door, a chemical directive intended for paint on metal will not work.

Tip: In order not to spend a lot of time looking for the right liquid, it's easier to consult with the store's distributor. As a rule, the more aggressive and effective the "wash", the more harmful, so it is important to follow all precautions.

Attention: Chemical "washes" of paints are harmful to health, regardless of the form in which they are produced:

After one or another composition is offered, be sure to carefully read the instructions for use. Perhaps it will be a highly toxic liquid agent that can only be handled in a respirator and work gloves. Or a store consultant will offer a ready-made liquid paint remover for a metal door. No worse than a gel or dry mixture of components that needs to be diluted.

It does not make sense to advise a specific remedy, it is easier to buy what is in the stores of this region. Paste and gel are applied to uneven, carved and profiled surfaces. A suitable reagent can also be selected from the catalog, it is also worth purchasing mineral kerosene along with them, which removes the applied agent with the remnants of old paint. Sometimes additional flushing of the surface with solvent, white spirit or water is required, depending on the instructions in the instructions.

The chemical reagent may not begin its action immediately, but will show the result in a few hours. Read the instructions carefully so as not to say that the remedy did not work. During the specified period, the "wash" will soften all layers of paint to a solid base. Only after that with a spatula can you carefully remove the door paint with your hands. An ordinary metal brush or any suitable device is also suitable.

Attention: Any reagent is applied to the prepared surface, from which peeled layers are pre-cleaned, which themselves lag behind and are easily torn off with a spatula. "Wash" is applied only to a durable layer of paint, this reduces the consumption of a chemical reagent.

Reminder: When working with reagents, wear protective clothing, goggles and a respirator, rubber gloves and closed shoes.

How is paint removed from a metal surface?

While a wooden door can be repainted multiple times, a metal surface will resist repeated repainting, especially if it is an exterior door that is subject to temperature fluctuations. We have to update the surface - remove the paint from the metal door. It is removed with special or improvised devices. For example, a grinder or a universal tool with nozzles that can clean off paint is used.

The door leaf must be removed from the hinges before processing, the fittings and decorative trims are removed from it and taken out into the yard for further processing. To remove paint in the simplest ways, use a thermal gun (building hair dryer), a special liquid for removing paint, kerosene, sandpaper, a spatula and a grinder. There should be no illusion that this is very simple - with any tool and effective chemicals, you still have to make some effort.

Without a suitable liquid, it will be difficult to remove old paint from metal doors with one spatula or a hard nozzle. Using only one tool, it is easy to damage the smooth surface of the metal, and even a layer of fresh paint will not hide the defect. After processing the door for painting, it is desirable to grind the metal surface with a special nozzle or emery cloth, although this is less effective manually.

A sander is a great tool for removing old layers of paint, provided you choose the right attachment. If there are no other options, they install a head with medium spraying and work at low speeds, that is, at low power. It is important to monitor the process so as not to damage the doors. If the nozzle and the load on the tool are chosen correctly, then the work will not take much time. Only the nozzle needs to be periodically cleaned from dry paint, from which the head quickly clogs. The cleaner the nozzle, the more effectively it works on the surface.

When processing with a grinder and other tools, there will be a lot of suspension from the paint being removed, even on the street. Abrasive attachments clog quickly and require cleaning, so it's important to consider that this is a fairly "dirty" job, so it's done in the yard.

A thermal gun is also suitable for such work, if it is not at hand, then you can rent it or borrow it from friends before removing the paint from the door prepared for work. This tool melts the paint, which is then carefully removed with a metal brush or spatula. For the same purposes, a building hair dryer and a blowtorch are used, directing a hot jet to the surface to be treated.

Attention: Take all precautions, as the surface of a metal door becomes hot during heat treatment. Try not to touch the door with your hands, so as not to get burned, especially since immediately after warming up, it is most effective to work on paint that bubbles and melts.

Processing of the old painted surface with the help of high temperature is possible only for metal. If you clean a wooden door in this way, it can burn out. Stained glass windows also have to be removed beforehand so that the glass does not melt.

Tip: When removing paint thermally, the smell of burning and the pungent smell of chemicals are inevitable, so all work is done in an open area. It is not recommended to blurt out the paint on the balcony or loggia of an apartment building - take the doors out of the entrance to the courtyard.

It is advisable to warn family members and neighbors so that there is no dissatisfaction, allergic reactions and the likelihood of poisoning with burning through drafts in the window.

When processing with a grinder and other tools, there will be a lot of suspension from the paint being removed, even on the street. Abrasive tips clog quickly and require cleaning, so it's important to consider that this is quite a "dirty" job. Of all the "hot tools" for removing old paint from a wooden door, only a building hair dryer is suitable. But they also need to be careful.

Tip: Whatever method you choose to remove paint from old doors, there will be costs and little pleasant moments everywhere. Do not be disappointed and leave the work in the middle. There is a possibility that you need to change the tool, nozzle or temperature. In any case, it will be a useful experience. About how professionals work to remove door paint - video at the end of the article.

How to properly remove paint from an old wooden door?

Many people think that an old wooden door is not worth the trouble of removing reusable paint. But this is true for cheap interior doors, which are still found in old standard-plan houses. Yes, the frame upholstered with plywood is not of particular value, and it is better to buy a new door leaf for the design of the apartment. But when it comes to a quality solid oak product or a real masterpiece carved by a master, such a door “does not ask” for a landfill. With proper updating and replacement of accessories, it will serve for a long time. Perhaps the paint was already removed from the door in the old fashioned way - with a solution based on caustic soda.

Wood differs from metal, stone and synthetic surfaces by its characteristic texture, which is easily damaged when working with sharp metal objects. Care must be taken not to break the integrity of the fibers by tilting the spatula or scraper along the pattern on the wood. In those places that are milled, it is important to work most carefully so as not to damage the pattern or the convex surfaces of the pattern. In the corners they work with any wedge-shaped tool.

When working with chemicals, be sure to protect yourself:

• work clothes with long sleeves;
• respirator;
• glasses;
• thick rubber gloves.

When opening a jar of reagent and working with its application, it is necessary to be extremely careful so that chemicals do not get on the skin or in the eyes. If the drops nevertheless accidentally get on open areas of the body, they must be urgently washed off, and with signs of irritation, consult a doctor. And do not start working until you read the instructions - how to remove paint from a wooden door with the purchased "wash".

Attention: Each type of paint needs its own type of special chemical wash - the mismatch of the reagent with the surface layer of paint is the main reason for failure!

With any method of cleaning the door from old layers, it is recommended that all work be carried out in open space. When using an electrical tool, be careful to make sure that the carrying case is in good condition and that the mains voltage is sufficient to operate the tool. You can not turn on the tool at maximum speed, in enhanced mode. It is better to check the efficiency of the nozzle not on the main surface, but on the end sections - from below or above the door. With an inept hand, if the sanding wheel is rotated too fast, it is easy to damage even fairly strong wood.

Not every heat treatment tool is suitable for heating old paint on the surface of doors - it can ignite and burn out. Do not use a gas burner with an open flame, only hot air. A building hair dryer is suitable, where the temperature of the supplied jet should heat up the paint, but not destroy the wood. At the same time, specialists use nozzle nozzles that create a jet that distributes heated air.

Upon completion of the work, it is necessary to remove not only the remnants of the paint, but also the “wash” itself. Before painting with new enamel, the wood must be sanded to a smooth state. If there are cracks, notches and other defects, they must be puttied. Only after the oil paint has been removed from the wood, all defects have been eliminated, the wood has been treated with a primer, you can proceed to painting. The primer must dry completely, and only after that they proceed to update the old door with new paint.

From the power tool when removing paint, the greatest efficiency was shown by:

• vibration grinder (removes a thin layer);
• belt grinder (access to hard-to-cut places);
• angle grinder (rough grinding and access to corners);
• scrapers and scrapers (for a flat surface);
• "Bulgarian" with brushes-brushes.

If you have any questions about removing paint from wooden doors, we recommend the video:

It's time to renovate, and you've come to the conclusion that old doors need updating. You are not going to buy and install new ones. To begin the restoration, you will need to remove the old paint.

This operation is performed in several ways. But in any case, you have to remove the door from the hinges. Preferably work outside. But if there is no possibility, it is laid in the middle of the room, substituting supports. Before cleaning the door from the old coating, you need to free it from the fittings, dismantle the hinges, and clean it of dirt.

Cleaning methods

There are several ways. Let's consider them in order.

thermal method

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

To start cleaning it, you will have to get an industrial hair dryer in advance. The material to be cleaned begins to bubble when heated.

To clean the door, the coating is removed with a sharp spatula. Handle the hair dryer carefully so as not to accidentally damage it!

The technology of the thermal method is simple, but this method is not suitable in all cases. With this method, you can clean the old layer only if the base is wood. Plastic from heating can begin to deform.

Another disadvantage of the thermal method is the release of toxic fumes. Therefore, it is recommended to do this on the street. In extreme cases, you need to open the windows and put on a respirator.

thermal method

mechanical method

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

• spatulas;
• Bulgarian;
• wire brush;
• flat grinder.

Unfortunately, sandpaper quickly deteriorates on a typewriter. Therefore, it is rarely used to remove old coatings over large areas.

First, it is processed by a grinder. Then the paint is cleaned with a metal brush. The rest is scraped off with spatulas. This technology is labor intensive. Without the use of physical force, it will not be possible to clean the old coating.

Important! When the paint layer is peeled off mechanically, it is accompanied by a large amount of dust. The operation must be carried out carefully so that the base does not get damaged.

Chemical method

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

• solvents;
• acids;
• alkalis;
• special blends.

The solvent is applied to the door. Then you need to wait until the coating becomes softer. If the door has been painted with several layers, it may be necessary to apply the solvent compound several times.

The exfoliated layers are cleaned with a spatula. Sometimes they dissolve completely, all that remains is to rinse everything.

Important! Solvents are toxic, so you can only wash off the paint in this way on the street. It dissolves quickly, but the chemical smell will last a very long time.

How to wash off paint from a metal sheet?

A wooden door can be touched up periodically, but metal doors require a different approach. They are exposed to the weather all the time. To update them, you need to clear the old layer. For this, a grinder or a drill equipped with special nozzles is used.

Before processing, the door is removed from the hinges and the fittings are dismantled. Work should preferably be done outdoors. The coating can be removed with a variety of tools and means:

• kerosene;
• sandpaper;
• spatula;
• grinder.

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

It will not be possible to clean with one spatula, you will need a hard nozzle or a good solvent. With only one tool, you can scratch a smooth metal surface. This defect subsequently cannot be hidden even under a thick layer of paint.

Steel is machined. Of course, you can do this with sandpaper, but the speed of such work leaves much to be desired.

The grinder can easily cope with old layers, but only if the nozzles are correctly selected. Usually work is carried out with a medium spray head. The speed of rotation of the head should be minimal. Work must be done carefully so as not to accidentally damage the door.

The right nozzle helps you get the job done quickly. The head needs to be constantly cleaned - it quickly becomes clogged with debris particles. The efficiency of the work depends on the cleanliness of the nozzle.

After any method of removal, be sure to sand the surface to achieve smoothness. If cracks are found on the canvas, they are covered with putty. Before starting to apply paint, the surface is primed. When the primer dries well, you can start painting.

How to clean the door from water emulsion?

How can you wash water emulsion? Today, there are many products on the market that help wash off various coatings from the surface. To cope with this material, you can use the most popular means.

Wash "Estate"

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

• tree;
• concrete;
• metal.

The wash does not contain harmful aggressive substances, therefore it is completely harmless to wood. Since the structure is gel-like, it is easy to process the surface with it. When it dries, the coating begins to delaminate.

Working Method:

1. apply the composition with a brush on the surface of the canvas;
2. wait 20 minutes;
3. clean the loose layer with a spatula;
4. rinse the door with warm water.

"Set Boya Sokucu"

A special wash designed to work with a water-based emulsion.

Application technology:

• lubricate the surface with a wash;
• wait 10 minutes;
• clean the raised coating with a spatula;
• if it was not possible to immediately wash everything off, the procedure is repeated.

After removing the emulsion with a washing solution, the surface is wiped with a nitrocellulose solvent and then washed with clean water.

How to wash off oil paint?

To remove such a coating from a metal sheet, the following technological sequence must be observed:

• 1.5 kg of quicklime is diluted in water until a creamy mass is obtained.
• the door is covered with it and left for 12 hours.
• the old layer is washed off.

To wash off the oil coating from the wooden canvas, you need to moisten the surface with water and pour soda ash. Cover the door with damp burlap. It should not dry out, so it needs to be watered every hour. The layer will peel off easily the next day.

Important! Chemical removal requires mandatory compliance with safety regulations. Rubber gloves should be worn on the hands, eyes should be covered with special glasses. A special bandage will protect the lungs from toxic fumes. Chemical solution that gets on the body should be washed off immediately with water.

As mentioned above, you can clean the surface of the coating in different ways. It all depends on conditions and opportunities. It is difficult to advise anything specific, because each owner has his own approach to this issue.

A comparison of the removal efficiency with a hair dryer and a special cleanser is shown in the video below.

If you started a do-it-yourself repair in the house, then be sure to pay attention to the condition of the doors, windows and floor. 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 solid wooden door, but the paint on it has peeled off and cracked from time to time, do not rush to throw it away, but try to update it. To do this, you need to know how to remove the old paint from the doors.

Peculiarities

Before the canvas is repainted, all layers of the old paintwork must be completely removed. Otherwise, it will look not only not aesthetically pleasing, but also not close. There are several options for removing old paint from a wooden surface. The most common ways:

• Chemical;
• Mechanical;
• Thermal.

Chemical

The chemical method is considered the fastest. Here they use different washes for paints. They must contain solvents to soften paints. This makes it possible to remove it with a simple construction spatula (metal).

Immediately prepare all the materials and tools that you will need for work:

• chemical stripping agent;
• brushes;
• solvent;
• putty knife;
• protective glasses;
• gloves.

Now let's start the process, guided by the video:

1. First, remove the door from the hinges, and also remove all the locks, as shown in the photo. Work is best done in a utility room or in a separate room;
2. Using a brush, apply a wash on the old canvas;
3. Let it brew and start rubbing until the paint starts to peel off;
4. Peeling paint can be removed with a spatula, and residues can be removed with sandpaper.

Please note that there are special chemical washes for different types of paints. If you take the wrong solvent, there will be no effect.

In addition, all chemical compounds are toxic, so you need to work with gloves and goggles in the open air or in ventilated areas.

To remove old paint from a wooden canvas, a special chemical paste is also used, which is prepared from caustic soda and oatmeal. You can prepare such a composition yourself:

1. Caustic soda is completely soluble in water;
2. Then add oatmeal and stir until you get a paste-like mixture, as shown in the photo.

This composition is usually used for doors with a complex shape. Also, such a paste is best used when removing a multi-layer coating and in hard-to-reach places. For the best effect, the composition must be applied to the canvas in a thick layer. After the paint begins to bubble, remove the paste with a scraper along with the old coating, and then rinse the surface with water pressure. This chemical composition must be handled carefully so as not to burn the skin with it.

Mechanical

To work mechanically, you need to prepare:

• scraper;
• chisel;
• grinder or grinder.

Of course, this way of working is long, and besides, you can get injured. However, sometimes without knives and other sharp objects it is difficult to clean the product from paint in hard-to-reach places.

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

Thermal

A building dryer is an indispensable tool for heat treatment of doors covered with old paint. Modern hair dryers have a heat regulator, with which you can soften the paintwork on a wooden surface, and then clean it with a knife, as shown in the photo.

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

If you are going to paint the restored canvas again with your own hands, it will not cost you much work. We can only advise you to carry out trial work first from the “wrong side” of the door. Then on the other hand you will not make possible mistakes.

Summing up

Wooden doors are considered the most durable, and after restoration, you can not tint them for five years. Interroom doors will last even longer, as they are installed indoors and are not exposed to various weather influences.

Sometimes, after repair work, interior doors need to be replaced or updated, but some people do not have the opportunity to purchase new ones or do not want to throw away the old ones. Designs can be made from a solid array, be carved, be of value. Then the question arises of how to remove the old paint from the door for further updating and fit it into the interior of the room.

Cleaning the door panels from the old coating will require effort, especially if several layers of paints and varnishes have been applied. Having completed this time-consuming task, the result of applying a new coating will surely please the owners - it will give the structure an updated look.

If you neglect this stage of updating, the result can be unpleasantly surprising. The new coating will lie unevenly, repeat all smudges, cracks. All paints and varnishes are composed of chemicals, so it is not known what reaction to expect when two dyes interact in different products. Layers may bulge and color may not be as expected.

Having decided on the independent removal of the old painted layer, you need to determine the most appropriate method of carrying out the work. The choice of method directly depends on the material of the door leaf. Wood, plywood, pressed sawdust or metal require a different approach. The methods applicable when removing the painted layer from metal are not at all suitable for wood.

When starting to work on removing the paintwork, take into account the following parameters:

• canvas material;
• number of dry layers;
• type of previously used paints and varnishes.

Considering all these points, it will be possible with less effort to determine the most suitable reagent or tool for removing the ink base. In addition to the work of removing old paint from wooden doors, they clean the surface and close up cracks. Before carrying out any manipulations, it is desirable to remove the structure from the hinges.

Only after carrying out the preparatory work, you can start applying a new paint.

Methods for removing paint from a door depending on the material

To decide how to remove old paint from a door at home, you need to determine the most appropriate cleaning method.

There are three types:

• chemical - the use of chemicals;
• mechanical (instrumental);
• thermal - exposure to high temperature.

Sometimes, in order to perform better work, it is necessary to combine two methods.

chemical method

The chemical method of removal is the most convenient and takes little time. This is a method without the use of special equipment, electricity. Suitable for removing heat-resistant coatings that are not amenable to heat.

To select the correct type of chemical reagent, you need to know what material was previously used. A consultant from a building supermarket will help you choose a special “wash”. Before using it, you must study the instructions, as well as protect yourself with personal protective equipment. When working with toxic solvents, you will need a respirator - be sure to use gloves, goggles.

What solvents are used?

For convenience, "washes" are available in different forms. This allows them to be used on any surface:

• liquid reagents;
• pastes;
• jelly;
• dry mixes for preparation of solutions.

To dissolve paint and varnish coatings, the following types of solvents are used:

• based on white spirit for dissolving oil, nitrocellulose, pentaphthalic paints and varnishes from a plank surface;
• products based on caustic soda or caustic alkali (dissolve acrylic and water-based paints).

Before treatment with a reagent, the surface should be cleaned of contaminants. The substance is applied for about 30 minutes, then the softened layer is removed with an iron spatula. If necessary, the procedure is repeated until the complete removal of the colored layer.

mechanical method

Before deciding how best to mechanically clean a wooden door of old paint, you need to acquire the necessary equipment. Machining and fiberboard will require more effort than using a "wash".

Dry layers can be removed manually: sandpaper, spatula, metal brush. This kind of work takes a lot of time and effort. It is easier to do this with the help of electric tools that can be rented at a hardware store, from friends.

With the help of a knife with a spatula, paint is well removed in hard-to-reach places. Then, the canvas is processed with coarse sandpaper.

Precautionary measures

It is better to remove paint from the door leaf mechanically on the street. When processing with tools, dust is generated, so it is recommended to clean the surface a little, moisten with plain water. In order not to breathe dust, you need to stock up on a respirator or mask.

For mechanical cleaning, you can use a piece of glass. Be very careful not to cut yourself or damage the wood surface (it is recommended to wear thick protective gloves). Remove unnecessary layers along the wood fibers.

thermal method

The thermal method of removing the old dye is based on heating the layers until they soften. Since high temperatures are used during operation, this method is not suitable for flammable materials such as plywood. When working with a wooden door, you need to choose the appropriate temperature regime.

Expensive fittings, jewelry, glass are removed before all work is done so that they do not melt or otherwise be damaged. The surface is cleaned of dirt, dust, debris. Remove the paint at the moment when it softens and bubbles

Important! When using the heating method, care must be taken not to burn yourself on a hot surface, especially if a metal door is being processed.

Thermal heating is best carried out outdoors to avoid the appearance of a pungent chemical odor and toxic volatile substances.

Tools for the job

The following tools are used to heat the painted surface:

• thermal gun (melts paint - easier to remove with a knife, brush);
• hair dryer (construction) - used for wood, can be used indoors, the temperature is regulated;
• gas burner;
• blowtorch;
• iron with foil.

The mechanical cleaning method, in addition to sandpaper, a spatula, a knife, a metal brush, involves the use of such power tools:

• grinder equipped with a grinding nozzle;
• Sander;
• drill with a brush for metal.

For chemical cleaning, you will need a spatula.

Having figured out how to effectively clean a wooden door from paint, you can begin the processing process. These methods will help save on the purchase of a new design and ennoble the old one.

During the period of repair work, it often turns out that the old door does not fit the new environment either in style or in color. But it does not always require replacement. If the canvas is made soundly, of high quality, you don’t need to get rid of an expensive item and spend money on acquiring a new one, but only carry out procedures for cleaning it and preparing it for new staining. This takes into account the material from which the doors are made, the depth of penetration of the old paint layer into the canvas, the number of layers.

Bringing the old door back to life

The easiest option, but costly, would be to replace the old, shabby wooden door leaf with a new one made of MDF, hollow inside. A zealous owner will not throw away the old door, but will begin to restore it if:

• it is made of oak or other dense material that will last for several decades;
• has dimensions that differ from those accepted by the standard, especially in stalins with high ceilings. The manufacture of such a canvas to order will cost the owner a pretty penny;
• has an unusual decoration with carvings;
• the owners are creative people who can make an art object out of an ordinary wooden door.

Cleaning the door of paint

The procedure for bringing an old wooden product into proper form is conditionally divided into several stages:

• removal of the old layer;
• door repair, preparation of its canvas for a new painting;
• fresh paint.

In order for the product to receive a new life, to serve the owners for the prescribed period, there were no swelling and delamination, it is necessary to remove the old paint from the doors. Among the various methods, there are several main ones:

• thermal;
• mechanical;
• chemical.

Heat treatment

Heat treatment is carried out by directing hot air to the door. Such purification occurs when using gas burners, building hair dryers. The advantage of this method of freeing a wooden door from old paint is the absence of dust, but the disadvantage is that the surface being cleaned is more likely to ignite. Such procedures are carried out in the open air, with the use of personal protective equipment (respirators, masks), they have a tank of water on hand to destroy the possible occurrence of a fire in the bud. It is used in cases where there are several layers of coating on a wooden surface. Under the influence of hot air, the previously applied coating swells, it is scraped off with a spatula.

mechanical cleaning

You can clean the door of paint with scrapers, spatulas, brushes for metal. The door is removed from the hinges, laid in a horizontal position, with the help of improvised materials, a grinder removes the paint. The method is not effective due to dust, as well as possible damage to the wooden surface.

Chemical cleaning

It is characterized by obtaining a positive result, is in the greatest demand due to the speed of action of washing reagents, which, when applied to the old paint layer, soften it, thereby making it easier.

Attention!

Work is carried out in the open air or with a constant supply of fresh air due to the specific smell of flushing agents.

General scheme for surface cleaning and preparation for painting

In life, all 3 cleaning methods are used, since one is often ineffective. To remove the paint from the doors, it is removed from the hinges, laid on a horizontal surface, the handles and locks are unscrewed. To bring the door into proper shape, before painting, remove the old coating in any of the ways, grind the surface, removing small defects, chips, repair scratches, more serious defects with putty.

In order to qualitatively remove old paint from the doors, materials, tools and protective equipment are prepared:

• solvent;
• brushes;
• spatulas;
• gloves and goggles;
• Sander;
• wood putty;
• skin of different grain sizes.

Protect hands with rubber gloves, and eyes with glasses, apply the drug with a brush, covering the entire surface of the door.

Types of washes

Paint washes are available in the form of:

• powders;
• pastes;
• gels;
• liquids.

From a wooden surface, first, with a spatula, remove layers that peel off by themselves, then, with a brush, apply a wash to dense layers of the coating. The speed of action of the agent is several minutes to a day. When choosing washes, one should take into account on what basis the coloring composition was made, otherwise, if the solvent is chosen incorrectly, the idea to remove old paint from a wooden door is doomed to failure and leads to expenses for buying a new washer. Distinguish:

• various liquid solvents based on white spirit are used to remove PF, NC, oil paints;
• masters make a special washing paste, consisting of caustic soda and oatmeal. Removes water-based,. Such a paste is 100% effective in places with complex geometry with the presence of wooden curls, monograms. It is applied in a thick layer on a tree, waiting for the paint to swell, removed with scrapers, washed with water under pressure, removing an aggressive wash;
• modern washes, which are gels that can soften the old coating in 15-20 minutes. With their help remove any kind of paint.

Attention!

The task of the wash is to penetrate the paint, soften it, swell, without harming the wooden surface.

Stages of work

3. Spray gun. The paint is well mixed, if it is too thick, it is diluted with a slightly suitable solvent. Pour into the spray gun compartment, set the desired pressure and size of drops when spraying by test painting an unnecessary piece of wood. They put on protective equipment (goggles, a respirator, gloves) and paint, moving their hand with a gun from the bottom up.

Iron door cleaning

Entrance doors are usually made of metal. They are constantly exposed to the weather. Therefore, they cannot simply be tinted like wood. The paint layer is completely removed from them. For cleaning you will need:

• acetone or white spirit;
• skin of different grain sizes;
• Sander;
• putty knife.

Before work, the metal sheet is removed from the hinges and laid in a horizontal position. The colored layers are removed with a grinder, using different nozzles, depending on the thickness of the previous layer. Then the small remnants of the layer are covered with a solvent and left to swell. The swollen paint is removed with a spatula. As well as from a wooden surface, a colorful coating is removed from a metal door by thermal and chemical means. When using chemical washes, the preparation is immediately removed from the surface after the paint is removed by cleaning the door with solvent and water. The cleaned surface is leveled, freed from cracks and flaws, using automotive putty, in places of damage, then sanded by hand or with a grinder.

Painting a metal door

Entrance doors have a large surface, so they are preferred to be painted with a spray gun or with a roller. Painting starts from the top, moving down and trying not to go on the painted layers. After 15-20 minutes, light and unpainted places are re-stained. If streaks appear during painting and dry up, they are protected with sandpaper after the surface has completely dried and the entire surface is re-painted. The loops are also painted over in the desired color. Since the paint has a strong chemical smell that does not disappear for a long time, metal products are painted on the street or in a utility room with open doors and windows.

Attention!

Do not paint in rainy weather and frost. At high humidity there is no strong adhesion of the paint to the product, and in the cold the paint thickens and does not adhere well to the surface.

To avoid unpleasant surprises, experts advise that even with the complete removal of the old coating, use a new paint of the same brand. In this case, the owners will avoid possible problems in the form of small blisters of paint in different places. Then the updated product will not stand out as an unsightly stain against the backdrop of a fresh repair.
