How to clean the door of old paint. How to remove old paint from doors. How to remove paint from a metal door

Wooden painted doors that are not of high quality may sometimes need restoration, namely the removal of a layer of paint that can swell, crack or have other damage.

Renovating an old door is a good thing to do with all responsibility in order to create a new masterpiece. So it pays to be patient and get to work.

There are several ways to remove old paint:

Method number 1

You need to take a deep container, pour water into it and pour caustic soda in such an amount that the resulting mixture was similar to liquid sour cream.

It is worth adding oatmeal to this mixture, which will help to make a homogeneous paste or a kind of “scrub”.
This very “scrub” should be applied in a thick layer on door leaf and leave for a certain period of time, approximately 10 to 30 minutes. As soon as you notice that the paint begins to soften, this is a signal that it is worth starting the next process.

Using a flat spatula, without pressing on it, you need to remove old layer paints. It is worth remembering that you need to work in the direction in which the fibers of the tree are located.
Using a triangular spatula or a regular razor, you can remove paint from hard-to-reach places. After that, it is worth wiping the structure well and covering it with white spirit.

The door leaf must be left to dry completely, only after that you can start repainting the door.

Method number 2

If your door has a thin enough layer of paint, no more than 1 cm, and it is swollen, you can purchase a special product in the store that softens the paint. All that is needed is to apply it to the surface of the structure, as indicated on the package, then wait a bit and remove the paint with a scraper.

Method number 3

You can use grandfather's method proven over the years. Worth it with blowtorch warm up the paint, then scrape off the old layer with a spatula. Then everything is polished with sandpaper and covered with white spirit. It should be noted that this is not a very convenient way, which provides a lot of inconvenience.

And in order to avoid such costly, in a temporary sense, processes, you need to purchase high-quality wooden ones that last for many years. The company "DM-Service", which operates on the market door structures for more than 6 years, can offer just such options, which, moreover, will have affordable price and great design.

There are several ways to remove paint from a door surface. This task is not easy: you have to put in enough effort. And yet, armed with a tool and knowledge, even very difficult work can be done.

It will be problematic to restore the door during the repair, or simply refresh the color of the canvas if the surface is not prepared. Most often, the sash is covered with several layers of old paint, has noticeable bumps and smudges. Even using the most expensive paint, the finish may not be what you want.

In addition, the old coating may react with the new, because it is not always possible to understand which chemical composition had a previous dye. Therefore, it is better to remove the old layer, otherwise it will lead to cracking, swelling and the formation of bald spots on the coating.

must be carefully removed old paint and in the event that the old coating had dark color, and now light light shades have been chosen for the product. Overlapping the previous layer will be difficult: the dark color will show through. As a result, the canvas may acquire a completely incomprehensible shade, or several layers of paint will have to be used. At the same time, it should be noted that painting in several layers has another disadvantage - the doors will begin to close worse, as the layers begin to accumulate at the ends. It is not necessary to remove the paint on the upper and lower ends, it is enough just to sand them, but only if the shade of the old paint material matches the new one.

It is sometimes necessary to remove the old coating partially, from the ends or from the side where the door is sheathed with leatherette. Unfortunately, this is a complex process, and it will take a lot of effort to achieve the desired result. Used to remove paint from wood. special means, and the metal door is prepared for a new painting in a different way.

Removing paint with chemicals

The chemical method is quite effective. Special fluid can be purchased at any hardware store. Only the agent must be suitable for the corresponding coating. For example, the composition will not work if they are removed oil paint, and it was intended for coating on metal. It is worth warning that the products are unsafe for health. Solutions are sold in dry, liquid, pasty form.

When choosing a tool, you need to carefully study the instructions for use. The liquid can be highly toxic and will require a respirator and work gloves to handle. It is pointless to recommend a certain remedy, so it is best to purchase the one that is. Paste and gel are most often used on uneven surfaces. In addition, it is necessary to buy mineral kerosene to remove the agent and particles of old paint. Additional solvent treatment may also be required if it is written in the instructions.

After application, the product may not work immediately, but only after a few hours. Therefore, in order not to say that it did not work, you need to study the instructions before applying. For a certain time, the product will soften the old paint coating to the base. Then you can remove the old layer using a spatula or a metal brush.

It is worth noting that before applying the reagent, the surface must be prepared, namely, cleaned of peeled layers. To reduce the consumption of the product, it is applied to a durable layer of the painted surface. For work, you will need overalls, goggles, a respirator and rubberized gloves.

Cleaning a metal door from old paint

Repeatedly painted metal door does not look attractive, especially when exposed to temperature changes. To update the surface, it must be cleaned, for which special or improvised means are used. For example, a grinder or special tools with various nozzles are used.

Before starting the procedure, the door is removed from the hinges, then the fittings and decorating linings are dismantled from it, and they are taken out into the yard for processing. The easiest method to get rid of paint is to use a blow dryer, kerosene, paint remover, a spatula, and a cipher machine.

Without the use of the necessary remover, it is almost impossible to remove paint from the surface with a spatula alone, as it can damage the smooth surface of the metal. After removing the paint, it is recommended to grind the surface with a machine or sandpaper.

The grinder effectively removes the old layer, but for this you need to choose the right nozzle. If there is not a wide variety of nozzles, then a nozzle with medium spraying is used, processing a surface of low power. To make the work more efficient, the tool head sometimes needs to be cleaned of paint that is clogged there.

A building hair dryer can also be used to remove paint. The process consists in the fact that it melts the paint under the action of hot air pressure, after which the layer is removed with a spatula. In addition, when processing, you need to be careful, since the surface of the door is very hot, so you need to be careful not to touch it with body parts. It is best to remove the paint after warming up, when it begins to bubble. In this way, only metal surface. If this method is used for wooden door, then you can burn it. Glass inserts must be removed in advance so that they do not melt. It is also worth noting that the smell of burning will appear during processing, in connection with this, the procedure must be done on the street.

Cleaning a wooden door

Wood differs from metal and stone surfaces in texture, which can be easily damaged by sharp objects. Therefore, the processing must be done carefully so that the fibers retain their integrity, and the spatula must be tilted along the pattern. Using chemical reagents, it is necessary to protect yourself with a respirator, goggles and rubberized gloves. To prevent the product from getting on the skin, you need to open the jar and apply it carefully. If the substance comes into contact with the skin, it is necessary to immediately rinse it, and if irritation persists, consult a doctor.

With any processing method, it is best to work outdoors. When using a grinder, do not turn it on at maximum power. To verify the effectiveness of the nozzle, check it on the upper and lower ends of the door. If the rotation of the nozzle is too fast, even very strong wood can be damaged.

When using a thermal treatment method, any tool will not work to heat the surface, because you can easily burn through the wood. A hair dryer may be used as the temperature of the hot air heats up the paint without damaging the wood.

At the end of the work, you need to clean the surface. Before applying a new coat of paint, the doors are carefully sanded. The formed cracks and chips need to be puttied. Only after the above procedures can you start painting the door.

Items that have age have a special charm. if you have old door made of wood, but peeled off on it dye, very easy to give her 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? Existing product can be restored with my 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 select the most the best option, let's figure it out, but why 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 creative person, capable of creating a work of arts and crafts with his 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. thermal method built 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 get off 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.

Tools

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.

It will take sanding paper with a 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;
  • Remedies;

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 secure 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 paintwork material and choose the right 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, review the door to decide whether to paint new paint, or in case the wood is in good condition, maybe decide that the lacquer coating 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


Painting doors is one of the options for updating them. And the most common.

The design of painted doors can be quite different, the main thing here is to do everything right so that the coating looks new for a long time. Today we will decide whether it is possible to paint the doors water-based paint, as well as how to paint the doors correctly.

The video in this article will show the entire process of doing the work and from the photo you can see its individual stages.

Painting the door is done in three stages, each of which is quite important and will affect the final result. Let's immediately see what we have to do and estimate the amount of work.

Stripping the door Door painting begins in this. The surface will also depend on the correct removal of the previous coating. It must be clean and smooth. you will find out below.
Primer Doors primed for painting correctly will only contribute to the correct distribution of the dye and the quality of the connection. This largely determines the service life of the entire structure. Door painting is done only on a primed surface.
Dye application Coloring panel doors and any other fundamentally different. Liquid is simply applied to primed doors for painting. But how to paint the doors with a roller or other tool, we will consider a little later.

Choosing a material

If the paint on the door has burst or you are completely restoring it (see), you will need to choose the right dye. They are a large number of in retail.

The range of different compositions for covering wooden doors is quite wide. In order to make a worthy choice, you first need to determine what exactly you want to see as a result: to emphasize and preserve the natural beauty of wood, or to create a coating that will completely hide the original structure.

Depending on this, a person can buy:

  • Polyurethane, alkyd, acrylic, oil or perchlorovinyl based paint, as well as opaque enamel.
  • Tinted and transparent varnish, stain, oil impregnation. They will give the natural color a different shade or more brightness.
  • If you need odorless door paint, then it is worth paying attention to acrylic. He won't be here. But again, look at the photo of the flowers and choose the right shade. It is also worth knowing that when applying the coating, it will be slightly different.

Experts in this matter advise choosing:

  • Acrylic dyes with water base, because they spread well and cover the surface, besides, they have a comfortable enough consistency to work with a brush.
  • Paint and varnish alkyd materials- their main advantages are high water-repellent performance, good drying speed and resistance to temperature changes.
  • You can choose to cover and varnish. To paint the doors, the color of the lacquer You should choose the right shade for it, it must match the overall interior.

In order for the painted ones to be attractive and of high quality, experts recommend choosing materials belonging to the second group.

All due to the fact that they have the best indicators of resistance to various negative factors, which are enough in the bath. In addition, similar materials can be used to paint interior and exterior doors.

Attention; Coloring compositions made on the basis of alkyd resin must be applied to a surface that will be completely dry. Otherwise, if the paint is applied to damp wood, it will begin to flake and peel off due to bubbles appearing on it.

So:

  • Painting wooden surfaces is not carried out at once, you need to perform several layers. It often happens that there is a need to use two different formulations.
    First, an impregnation with a tinting effect is used, and only then a decorative layer is applied. It is extremely important to choose such compositions that would work in a duet. For example, before applying varnish, you can not use drying oil. Only stain is suitable for varnish.
  • If your plans are only to refresh the color of the doors using oil impregnation or stain, you will still need to apply at least two layers. How many of them will be needed in the end will depend entirely on the surface of the door. You can apply up to ten layers until the result that the person wants is achieved.

Step by step instructions for painting wooden doors

Tools needed for the job

After the paint is selected, you need to take care of the tools:

  • Gloves.
  • Rags.
  • Paint brushes.
  • roller.
  • Small spatula.
  • Emery skin.
  • Paint bath.
  • Masking tape.

Since the doors consist not only of canvas, but there are also other components, the first step that needs to be done in order to successfully paint wooden doors is to properly prepare them. You can, of course, paint only the canvas, but in this case the difference between the box and it will be noticeable to the naked eye.

So, painting the doors must begin with the following steps:

  • We remove the door from the hinges and lay it on the goats, stools or a table. If you decide to use alkyd products that have a pungent odor, then all work is best done outdoors.
  • If you cannot remove the canvas, then it must be blocked with wedges. They are arranged in such a way that the panel brush can reach all surfaces. The interlock must also prevent the doors from closing, which will inevitably damage the applied paint layer.

Attention: Experts still advise to remove the canvas, but if this is not possible, then resort to the second option described above.

Then we start to remove the accessories. If the handles and hinges are non-removable, then we seal them with tape or wrap them in paper, but foil is most suitable. We advise you to fix and seal the lock with tape.

Preparing the door for painting

This is very milestone work, which includes several stages. Treat it carefully and with special care. In this case, the painting of the doors will turn out one hundred percent.

Preparation takes place according to the following scheme:

  • At the very beginning, we remove all layers of paint, putty or primer that are available. As a result, the wood should be completely clean.
    For these purposes, you can use grinder or do makeshift fixture from a bar, wrapping it with sandpaper. If there is a building hair dryer, then it is best to use it, the process will be much easier.
    Layers of paint will bubble when heated and then removed with a spatula. You can also buy a special wash designed for wood. But such a tool is not cheap. How to remove paint from a door different options, you can read on the pages of our site.
  • Then we carry out the first grinding, which helps to eliminate small defects: scratches, remnants of the old coating or dents. To do this, use sandpaper or a machine that is connected to a vacuum cleaner.
  • The next stage of work will be puttying. Existing significant defects must be treated with a special wood putty of the desired color, if the coating is eventually transparent.
    If the doors are painted with an opaque compound, then the color will have absolutely no meaning. Do not forget about the gaps that exist between the lintel, jamb and canvas elements.
  • After the time specified in the instructions has passed, we grind the entire surface again. First, we use an abrasive skin that has a medium grain or nozzle on a typewriter, and then we apply a fine grain.
  • If there are deep flaws on the door, repair them with auto-filler, which does not include fiberglass. A similar option can be used if the painting will be carried out with opaque paint.

If, in the process of furnishing or renovating your home, you have a desire to update, freshen up or completely change appearance solid pieces of furniture made of wood - doors, floors, window sills, frames, platbands, cabinets, tables or chairs, then in this case there is pressing need first of all, remove the old paint from the tree, that is, prepare the surface for all subsequent work.

And if in the case of a new surface, the situation is quite simple: it needs to be sanded and then primed, then the old wooden surface will require much more time and effort to bring it into proper shape. The matter is also complicated by the fact that a tree is relatively soft material, and when removing paint from it, there is a risk of damaging its surface.

Is it necessary to remove paint from wood surfaces? This is perhaps the first question you ask yourself when you decide to do some kind of restoration work. After all, 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 one.

In this case, you should take a closer look at the surface to be treated: if the layer of old paint is thin, the paint does not lag behind the surface and there are no cracks on it, then minimal sanding will be enough, after which it will be possible to start re-painting.

  • the previous paint layer is too thick;
  • the surface has already been painted several times;
  • there are cracks on the layer of old paint;
  • the former layer bubbles and lags behind the surface;
  • you are going to use a different type of paintwork than the previous one.

How to remove old paint from wood

There are three main ways to remove old paint from a door or other wood surface:

  1. Mechanical
  2. Temperature
  3. Chemical

Mechanical way to remove the old layer of paint from the surface of the tree

This method consists in mechanical action on a previously painted surface. This is the first method that is tried to be used to clean the surface of a door, floor, window sill or any piece of wood furniture from old paint. In this case, it is simply scraped off with the appropriate tools:

  • spatula;
  • metal brush;
  • sandpaper;
  • chisels;
  • scraper.

Beyond simple hand tools requiring significant physical effort, you may need more serious power tools: an electric drill with a special nozzle for grinding and cleaning, Grinder or a grinder with a disc for grinding and cleaning.

The mechanical method of removing old paint is justified if the paint layer is already very old, and the paint peels off the surface easily, in layers. It's also a good idea to clean up old paint. mechanically With flat surfaces, or surfaces small area such as window frames.

However, when it comes to uneven decorative surfaces, for example, twisted, carved and curved elements on the door, furniture or architraves, simple mechanical removal will be too complicated, time consuming and ineffective. Another negative aspect of sanding is the inability to remove the entire paint, since it usually only makes the paint layer thinner, and in hard-to-reach places paint usually remains.

Temperature method for removing old paint from wood

An effective way to remove the old paint layer with your own hands is to heat it, followed by removing the peeling paint with a spatula.

How to remove old paint with a building hair dryer? To do this, you need to direct a stream of hot air from a hair dryer onto the treated paintwork surface. From exposure to heat, the paint softens and begins to swell, after which it is removed with a spatula, scraper or chisel. If there are depressions on the surface, the paint can be removed from them with a triangular spatula. In the absence of such, you can use a razor.

But remember that this process requires accuracy and caution, because if you handle the hair dryer and spatula ineptly, you can get hurt or damaged. wooden surface. You also need to keep in mind that it is difficult to remove oil paint with a hair dryer, because, unlike other types of paints, it does not exfoliate when heated, but melts, turning into a greasy soft substance that is difficult to remove with a spatula.

How to chemically remove old paint from wood

A tool for cleaning old paint from a door, frame, trim or furniture can be made by yourself or purchased ready-made. home remedy in this case, it is a solution of caustic soda. This method requires great care and appropriate protection of exposed areas of the body, that is, be sure to wear thick rubber gloves and unnecessary clothing. Next, you need to pour a solution of caustic soda into an unnecessary container and apply it with a brush to the painted surface. Continue application until the old paint begins to blister. After that, you need to clean off the paint with a spatula, scraper or chisel, and apply any degreasing agent to the treated surface, or at least wipe it with water.

It is much easier to remove old paint from wooden objects, purchase ready-made chemical agent, designed for a certain type of paint in combination with a wood surface. It is very important when using them to pay due attention to the protection of the skin, eyes and respiratory tract: protect your eyes with goggles or a mask, hands with gloves, and be sure to open the window while working.

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