Decoupage door. Old doors like new! What materials are used for decoupage?

Sometimes, after repair work, it is necessary to replace or update interior doors, 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.

How not to damage the door covering?

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:

• web 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 - application 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 MDF 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.

How to remove old paint from doors and cover with new as quickly as possible

In matters of repair, one of the important stages is the installation of a new door or the renewal of an existing one. If you have the financial opportunity, you can replace the old door, but if there is not enough money, then try to return the life of the old door structure. Read our article on how to do this.

Features of removing paintwork from doors

Painting doors is an alternative way to restore their attractive appearance. If there are several door structures in the house, then during restoration it is desirable to give them a single (or at least similar) shade. But before you start painting the door leaf, it must be carefully prepared. And for this you need to clean the old paint from the surface. You will also need to prepare the old door for a new painting, and only then it will be possible to apply a new layer of paint on it.

Do not be afraid to update old doors, because with the right approach to repair, they can become a decoration of any room. Remember the main rule - the paintwork should be applied evenly to the door leaf. Such an effect can be achieved only if the surface is properly prepared for the procedure, making its structure homogeneous. It is for this purpose that it is proposed to pre-clean off the old paint from the tree.

Compliance with the following rules will help you complete the preparatory procedures correctly:

• First, try to qualitatively clean the door of old paint . No traces of the old coating should remain on the surface of the canvas. If this requirement is not met, then in the future the old paintwork material will begin to swell, and the entire surface of the updated door will be damaged. You will do all the preparatory work yourself, so focus on its quality.
• After removing the old coating, the canvas must be leveled, removing potholes and small cracks. For these purposes, there is a special material - putty. When buying it, pay attention to such characteristics of the material as frost resistance and moisture resistance, as well as information regarding the temperature conditions under which the putty will retain its properties. There are varieties of material that do not tolerate excessive moisture and negative temperatures. This should be taken into account when purchasing.
• A separate issue is the purchase of varnish or paint for the restored door structure. It is better to choose cans with such compositions with one serial number - then you can be sure that the paint will not differ in its shade.

There are several ways to remove old paint from a wooden surface. If the door was painted in one layer, and the paint and varnish composition still retained its attractiveness, then the surface is only lightly sanded and a layer of paint of a new sample is applied on top. However, this should only be done if there are no cracks or damage on the old coating. It is better, of course, to remove the old paint. This process is carried out in the following ways:

• Heat the surface and remove the old paint from the doors, because it will become soft and pliable under thermal influence.
• Another good tool for removing old paint is scraping or sanding the wood. This method is classified as mechanical. It is distinguished by its laboriousness and duration, but it demonstrates a high degree of efficiency.
• You can also remove old paint by using a chemical method. It involves the use of special reagents called washes.

3 best ways to remove old paint from wood

mechanical way

One of the first thoughts that arises when looking at a layer of paint that needs to be removed is: “Yes, it will be the easiest to peel it off!”. And now the hands are already reaching for a grinder or a drill with grinding nozzles. We recommend not to rush and analyze the situation, because mechanical removal is not that inefficient, but it is not suitable for all products.

• Can the product be taken outside? There will be an incredible amount of dust and flying pieces of the coating, and if you start removing paint indoors, then you will have to start a major cleaning later. Plus, you will have to work in a respirator and glasses, which is also not very convenient.
• Is there a thick layer of paint on the product? Previous generations did not stand on ceremony with oil paint: they were tired of color - just cover the old layer with a new one. It turns out that on some Soviet doors, a layer cake of 4-5 layers of oil paint has accumulated, each of which is much thicker than the layer of acrylic paint that we use now. With the mechanical removal of such a layer, you will score more than one skin without achieving the desired result, and this is not only insulting, but also quite expensive.
• Is the product stationary? Removing varnish from the legs of a chair with a grinder is a good idea, but cleaning a window frame or skirting boards that you are not going to beat off the wall in this way is not very good - because of the risk of touching a wall or window with a grinding disc.
• Is the surface of the product flat? If the product has depressions or protrusions, then the mechanical method will not be the best choice for removing paint, as it will still remain in the joints and recesses.

It turns out that you can remove the paint by grinding if its layer is not thick and the surface is even, otherwise the effort spent on removing the coating will not be worth the result that you get.

Sometimes for thin layers it is enough to rub the coating with a metal brush and sand it with sandpaper with a medium abrasive. If the surface area is small, then this is the best way to remove paint without special tools and substances.

Chemical method

Quite quickly and easily, chemical washes, which are sold in hardware stores, will help to remove the old layer of paint. Only they, of course, do not wash off the paint, but rather soften it, so you still have to work with a spatula. Typically, such a product is applied to the product with a brush or roller, left, depending on the type of product and instructions - usually for 20-40 minutes, and then the softened layer is pryed off and scraped off with a spatula. If the first time it was possible to get rid of only part of the paint, then the procedure is repeated, but the smallest residues can be cleaned with sandpaper.

It is important, when buying such a wash, to check with the seller or make sure for yourself that it is suitable for your type of material and paint. You can save yourself the hassle of looking for a specific washer for your type of paint by purchasing an all-purpose cleaner. Also, think in advance about whether you can leave the room for the duration of the wash and then ventilate it well or take the product outside. If yes, then you can take a regular solvent-based paint remover, if not, then it is better to give preference to more modern expensive odorless gel washes. That's just the absence of smell does not mean that they are not toxic: with any wash it is necessary to work with gloves, and the room must be ventilated.

From the experience of builders, we can say that cheap Russian-made washes do not do well with old oil paint if it is applied in several layers. With more expensive foreign counterparts, this problem does not arise.

If you have caustic soda, then you can not spend money on special washes at all: add a little water to it, dissolve the soda, and then mix it with ground oatmeal to make a paste. Apply the paste to the product, wait about an hour until bubbles form, remove the paint with a spatula, and then degrease the surface. Gloves and ventilation are also relevant for this method.

Do not use plastic containers and tools when working with a wash, as they may deteriorate from exposure to chemicals. Also, do not use washes if plastic is located close to the wooden product.

thermal method

The latter method is considered preferable for removing paint from wood, since it can be done quickly, easily, inexpensively and without harm to the product itself. It consists in heating the paint to a temperature at which it begins to correct and release gas. This will cause it to bubble, and it will be easy for you to peel off the old layer by prying these bubbles with a spatula. But what is the best way to do it?

Heating with an open flame, such as a burner, is not only dangerous, but will also have questionable results. Yes, the paint will start bubbling, but fire can lead to drying out of the wood, burnt spots on the product, or poor-quality subsequent painting due to resins released during the treatment with a burner.

It is better to use a hair dryer, but not a household one, but a construction one. Its heating is hundreds of times stronger, and the paint begins to lag behind the wood literally before our eyes: just have time to pry it with a spatula. Of course, it’s scary for an inexperienced person to work with such a hair dryer: if you accidentally point a stream of hot air at yourself, the case will 100% end in a hospital. But subject to all security measures, this method beats all the others! If you have a person willing to lend you a blow dryer for a day.

Strong heating, as well as chemical processing, is not allowed if the product has plastic parts that cannot be dismantled. Also, do not heat the wall with a hair dryer in areas where the wiring passes, as this can lead to damage to it.

Or maybe not remove the old layer at all?

Yes, it is often necessary to remove the old layer of paint, especially when the paint has begun to crack and peel off or when the surface has become very uneven and bumpy due to the multi-layering. But you don't have to go through the long and complicated process of stripping paint by choosing a new coat on top of the old one.

The surface will have to be prepared: the oil paint must be sanded, removing the bumps, then washed with an alkaline solution, such as soap, primed with an alkyd or synthetic primer, and then apply a new layer. If after grinding the surface is still not leveled, the product can be puttied before priming.

If you want to get a translucent effect with a translucent wood texture, then the paint will have to be removed, even if painting a new layer on top of it is quite possible.

You will need some skill in removing paint from wood, but once you figure it out once, you can easily repeat the procedure if necessary. How exactly you will remove the coating is up to you, but, you see, now you have plenty to choose from.

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:

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 facilitating the removal of old paint.

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:

From a wooden surface, first, with a spatula, remove the layers that peel off themselves, then, with a brush, apply a wash to the 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, acrylic paints. 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

Before removing the paintwork with a remover:

1. The surface is wiped from dust.
2. Evenly cover the painted wood with a brush, without going over the same place twice.
3. The surface covered with a wash is left for the time indicated on the label, covered with a film for best effect.
4. Soon the reagent becomes brown or brown, the paint rears up, it is removed with a spatula, disposed of.
5. If the result is unsatisfactory, the procedure is repeated.
6. The cleaned surface is washed with an aqueous solution of vinegar, the door is wiped dry, and left for final drying in a draft.
7. After drying, the products proceed to puttying, sealing small cracks and chips.
8. Smooth the surfaces with fine sandpaper. With a grinder, this procedure is facilitated. Level and grind the surface, making movements in one direction to avoid roughness.
9. Dry rags remove dust, remnants of putty.
10. The door is ready for painting.

Painting a wooden door

Suitable for painting a street wooden door is oil paint, because it protects the tree from the action of rain, snow, frost. Prevents the appearance of the wood beetle. Paint doors:

1. With a brush. The paint in the jar is stirred, poured a little into a small wide container and, dipping lightly into the paint, paint the product, moving the brush in one direction. It is convenient to paint over small details and curls with a brush.
2. roller. If the surface is flat and large, a roller is used to apply an even layer. To do this, the paint is poured into a special trough and the roller is slightly dipped into the paint, the object is painted, moving the hand in one direction.
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.

Attention!

When streaks appear, they are immediately removed with a rag so that they do not freeze with ugly drops. Painting from a spray gun after 15-20 minutes is carried out again with incomplete painting of the tree.

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.

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.

mechanical way

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.

Removing paint

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.

cleaning

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.

Washing agents

"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.

Bleaching powder

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.

Items that have age have a special charm. If you have an old wooden door, but it has peeled off dye, very easy to give her a new life. It seems to be worth digging for, if you can easily buy a new one: a wide range is offered at the points of sale of building and finishing products. But is it necessary to replace a solid wood door with a modern product made of thin medium-density fibreboard, hollow in the middle and finished with a laminate finish, even if it looks like a Milan walnut? An existing product can be restored with your own hands. First you need to remove the paint from the wood doors.

We remove paint that is already outdated

Why repair a door?

Before considering how to remove paint from doors and choose the best option, let's figure out why to spend time and effort.

1. old woody doors are of high quality. They are made of solid wood, quite often oak served as the material for production, even if the sash is covered with paint.
2. Original old door panels. Old-plan apartments often have old doors, high, double-sided, paneled. You can’t buy these in the store, and custom-made will be expensive.
3. The door is beautiful. If you are lucky - and you are the owner of a door leaf richly decorated with carvings, throwing it in the trash will be blasphemy.
4. Art object. If you are a creative person who is able to create a creation of arts and crafts with your own hands, then a wooden sash is a wonderful field for art.

From the points described above, it can be seen that there are many reasons for reconstruction and repair, but you may have your own.

materials

In theory, there are three ways to get rid of outdated paint:

• Thermal. The thermal method is based on heating outdated paint until softened.
• Mechanical. The coating is removed using various scrapers, sandpaper. You can do the work manually or with an electric tool.
• Chemical. Dye finished off with chemicals, softened and removed.

In theory, everything is simple, but as practice has shown, it is very often necessary to use all three methods, due to the fact that chemistry does not dissolve all types of paint and varnish coatings, heating cannot remove the layer in the cavities, and the mechanical method, even with the help of an electric tool, is very difficult and dusty process. Thanks to this, you do not need to rely on any one option. It is better to stock up on the maximum considerable number of devices and funds.

To complete the door renovation plan, you will need to stock up on some devices and patience, due to the fact that, the fastest thing is to quickly remove the paint that is already outdated from wood doors, even after looking at the video for detailed instructions, it will not work.

Instruments

Hairdryer construction - a very necessary thing to shoot outdated paint. It looks and functions almost like a traditional hair dryer. That's just the air temperature gives out from 100 to 600 ° C. Because of this, handle it carefully so as not to get burned, and in no case use it instead of a hair dryer. And vice versa: if there is no building hair dryer, then you should not try to use an ordinary hair dryer. You won't get results.

In addition to the hair dryer, you can use other thermal processing options: a soldering lamp or an atmospheric burner. These instruments require special care in handling. You can easily overheat the area, and damage not only the paint, but the tree itself. In addition, these devices have open flames, so follow the safety rules. An infrared lamp is also used to heat the coating.

A cycle is a scraper with a metal blade and a handle. If it was not possible to acquire a specialized scraper, a spatula, or any other identical tool, will do.

You will need sanding paper with a wide variety of grains. Apart from paper, specialized abrasive sponges are the most practical, especially if there are reliefs on the surface, for example, carvings. It's great if you have a grinding machine at your disposal - using it significantly makes the process faster.

It can be manual or in the form of a nozzle on a drill. Both options may be needed. Drill bits come in the form of a disc or a cup.

• brushes and brushes;
• paint remover;
• means of protection;

An apron or clothes that you don’t mind damaging, gloves - ordinary, fabric and rubber, a respirator, glasses. Do not neglect the use of protective equipment: you want to remove paint from iron or wood doors, and not the skin from their own hands.

Consumables

Rags to remove dust, polymer ethylene to protect furniture and other items, adhesive tape - it’s hard to say right away what it can be useful for, but the fact that it can be useful for something is a fact.

On sale there are different washes for outdated paint. Try to determine the type of paintwork material and choose the appropriate chemistry.

Let's start working

The work ahead is quite polluted, and in the process, no matter how the coating is removed, rather bad smells arise. If you plan to do work indoors, cover the room environment with a film for protection and you need to check if there is a chance to ventilate the room.

Start the cleanup process outdated paint with the use of a building hair dryer. Many models have temperature adjustment - it must be selected experimentally. A hair dryer is often equipped with additional nozzles. Among them there is a scraper nozzle, it allows not only to direct a jet of hot air, but also to scrape off softened paint at the same time.

Where the coating cannot be removed with a hair dryer, use other options.

When the coating is mostly removed, the surface of the door leaf is additionally finished with sandpaper to remove the remaining areas of the coating and scuffing from the scraper.

Remove dust and inspect the surface. Perhaps, in certain places you need to putty flaws. Before filling in chips and dents, look through the door to decide whether to paint with new paint, or in case the wood is in good condition, maybe decide that varnishing will add more charm to the product.

Now you know how to remove paint that is already out of date with doors. The coating that is already outdated has been removed, and we proceed to the planned lining.

Restoration of doors and furniture

An easy way to update the surface of an interior door is to paint it. For such a procedure, it is not necessary to have special skills, or seek help from painters - everything can be done alone.

Methods for removing paint from wooden doors

Before painting a wooden door, you need to completely get rid of the old layer of paint. There are three ways to clean the surface.

Chemical method

Special chemical solutions are used - "old paint remover". The reagents included in the composition quickly soften the paint layer.

To do this, the mixture is applied to the surface of the door with a roller with a fine pile or a brush. As soon as a sufficient amount of solution has been applied, it is necessary to wait for a certain period (from 5 to 30 minutes). During this time, chemicals will be able to corrode all the paint. Then it will be easy to remove its remnants with a spatula.

Important! Before applying a new layer of paint, it is necessary to degrease the surface from the remnants of the wash.

This method of removing the old layer is very fast and does not require the use of force. But pay attention - during a chemical reaction, harmful substances will be released into the air. First you need to take care of the effective ventilation of the room. And also about a respirator - to protect the respiratory system. Hands must be protected with gloves.

mechanical way

Mechanical cleaning is the easiest option for cleaning. But at the same time, it is also the longest. It is most effective to use a grinder, with a circle-nozzle for sandpaper. You can also use an electric drill.

The procedure will be accompanied by the formation of a large amount of dust and dirt. So it is necessary to protect the airways with a respirator. You will also need goggles and gloves.

Before you start cleaning, you need to consider the grit of sandpaper and the type of wood. Too coarse paper grain can leave scratches or even depressions on the wood. Otherwise, before painting, you will have to additionally putty and prime all mechanical damage.

thermal method

The old layer can be easily removed if the surface is preheated. This option is called thermal. It is most convenient to heat the door with a building hair dryer, but if it is not available, you can use an ordinary iron and foil. The foil is applied to the surface, then warmed up from the iron. Next, you need to remove it and immediately start cleaning.

It should be borne in mind that old paint can ignite if overheated. It is important to acquire extinguishing agents, even if they are not useful. In addition, it is advisable to carry out the procedure away from the accumulation of wires or plastic objects, otherwise the high temperature will easily damage or destroy them.

Types of paints for wooden interior doors

For doors, it is worth choosing a water-based option - this variety is quick-drying, resistant to changes in humidity and temperature, and some subspecies are almost odorless. Stop at the following types:

• Water emulsion. Colored or white enamel, inexpensive, environmentally friendly. It is applied to the surface, under the future layer of varnish, since the composition does not have strength and with great activity - opening-closing - it will peel off. If humidity is increased in an apartment or house, then this defect cannot be avoided.
• Moisture resistant. Silicone or acrylic paint contains polymers that form a film on the surface that prevents the penetration of moisture. This is important for wooden structures and rooms where the humidity is constant - kitchen, bath, bathrooms.
• Lesser. This is a paint for wood doors or completely transparent. It gives the canvases a finished decorative look, emphasizing the natural beauty of the material. Unlike varnish, the composition is not transparent, which is why it has received the characteristic of glaze. The components allow you to smoothly make the transition to shades, linger on the natural pattern. Flawless on all surfaces - deaf, smooth or textured.
• Lucky. Inside the apartment, only water-based compositions are used - nitrolac will not work.
