Painting lining with water-based paint after antiseptic. What paint is better to paint the lining inside the house

This thin board is considered a truly versatile cladding, as it is perfect for any surface, both inside and outside the building. But at the same time, wood has significant drawbacks - it is subject not only to the influence environment(humidity, ultraviolet), but also damage by insects (woodworms), rodents. Besides, given material relatively easy to ignite.

Before considering the question of how to paint the lining, you should understand why do this at all?

The paintwork acts as a protective layer that protects the board from all negative external influences.
External processing of the material significantly increases its service life and allows you to keep the original shade of the cladding unchanged.
With the help of a properly selected coloring composition, you can change the texture of wood or simply (if necessary) update the appearance of the surface.
External processing of lining greatly facilitates the process of cleaning indoors. Such a board can be washed without worrying that it will subsequently “lead” due to absorbed moisture.

If a decision has been made on the advisability of surface treatment of the lining, then it should be decided what specific goal is pursued:

only to protect wood from damage;
to increase the service life while decorating (changing the appearance) of the surface.

The question of how to paint the lining inside the house does not consist only in choosing one or another coloring composition. In fact, this is a whole complex of activities, in which coloring itself is only the final stage. At the beginning of the article, the main operational disadvantages of wood were already noted. Therefore, before you start surface processing of the material, you need to carry out a few more operations.

If this is neglected, then after some time you may encounter such defects as cracking of the board or paint layer, “peeling” and peeling of the latter, and some others. In fact, it will soon become clear that time, labor, and money spent are all gone, and you need to start over.

Therefore, it would be more correct to start a conversation about how to paint the lining inside the house, precisely from the question of its preliminary processing.

How to paint lining inside the house

Drying

Any wood has a certain moisture content. According to existing regulations, its level in building materials made of wood should not exceed 22%. If the lining has already been installed and has been in operation for some time, then it is natural that it could absorb the moisture in the air. Therefore, such a lining needs to be dried. And it is better if the boards are dismantled.

This will allow not only to process them qualitatively, but also to detect existing defects that are invisible during a superficial examination. For example, a fungus reverse side boards.

Before further work with the lining, it should be sanded (sandpaper).

Flammability reduction

For this, compounds with the common name "flame retardants" are used. By the way, there are so-called "fire-fighting" paints on sale. But from our point of view, they will not give such an effect as special compositions, since flame retardants penetrate more deeply into the wood structure. It is advisable to use such paints to cover lining, which is operated in areas with a high degree of fire hazard. And then, as an addition to special compositions.

Damp protection

These funds (from fungus, mold, bacteria) are called antiseptics. The range of products is large - glazing compositions, surface and a number of others. Some of them contain harmful substances, therefore, to process the lining inside the premises, antiseptics are used specifically for " internal works". By the way, stain (colorless or tinted) and wax are effective protective agents. The latter, moreover, "makes" the board shine.

Padding

It is applied to lining from coniferous breeds of trees. Such boards, when the temperature rises, release resins, which sharply reduce the protective functions of the “finish” coating (paint, varnish). On sale there are special antiseptics - primers.

What is better to paint the lining

Protective

Acrylic varnishes

They preserve the texture of the material and at the same time play a role protective coating. It is advisable to apply the composition in two layers: the first is transparent, the next is tinted. Experts recommend products for interior work on water based.

Synthetic varnishes

Shine incomparably better. Plus to it, "smooth out" small roughnesses. But their use is specific, since most of these compounds contain harmful substances. They are mainly used for outdoor work, so a specialist consultation is necessary. They are clearly not suitable for processing lining in the kitchen, in the nursery and in a number of other rooms.

Decorative

Oil paints

Of all types paintwork materials- one of the cheapest. But their drying time is somewhat longer than that of analogues on a different basis. Plus - a specific smell. Before you paint the lining inside the house with such paint, you need to take care of the appropriate ambient temperature. In a cold room, such compositions dry out for a long time, and if there are also drafts and dust in it, then it will quickly settle on the lining. It makes no sense to explain how such a surface will then look like.

In addition, oil paints “fade” quite quickly, so even a recently painted surface does not look so attractive after a short time. Another significant “minus” is deep penetration into the structure of the tree. In fact, such paints seal all pores, and the material loses one of its main advantages - the ability to "breathe".

Based on this, such compositions should not be used to completely cover surfaces. If necessary, only for certain sections of the premises.

Acrylate paints

In addition to having a good shine, they are elastic. If the board is partially deformed (for example, due to temperature changes), then the paint will not crack or peel off. Such compositions are considered the most reliable and durable, but their cost is much higher than other paints and varnishes.

As an example, we will cite products such as Pinotex and its Russian (much cheaper) analogue Aquatex.

Speaking about how to paint the lining, it is worth noting that it is better to do this work with a brush, and not with a roller, and with a soft one.

Helpful Hints

If the board is degreased with an alkali solution, then the coloring composition will “adhere” to the base more qualitatively. This will allow you to forget about the next repair for a long time.
To increase the effectiveness of wood protection, paints and varnishes are applied in several layers. You need to be guided by the rule that 3 thin ones are better than 2 thick ones.
Painting work should not be carried out at elevated temperatures. Intensive drying of paint and varnish compositions will negatively affect the quality of the coating.
When processing boards, few people deal with their ends, and they require no less attention. For these parts of the lining, the whole complex of preparatory measures is also carried out.
Experts believe that for interior work on painting surfaces the best option(in terms of ecology) are acrylic scuba diving.

When choosing paint composition no need to "blindly" rely on the recommendations of the Seller. First of all, it is necessary to focus on the specifics of the premises and the conditions for its further operation.

Painting lining outside the house is important point room finishing. After all, this is where the impact of the external environment is greatest. The price of the material is quite high and as a result not correct painting lining will quickly become unusable.

How to paint the lining outside the house, we will analyze in detail today. Also on the video in this article and the photo you can see the individual stages of selection and material parameters.

Lining is a natural material. The best performance in terms of durability outside the building shows the finish of softwood wood, but it is not too durable when compared with metal or siding (see).

The following negative points affect the lining made of wood:

Humidity change, which occurs during the day, as well as when the season changes;
Negative temperatures outside in winter and heating in summer;
Ultra-violet rays, which gradually lead to the destruction of wood fibers;
Miscellaneous microorganisms, which are quite numerous in the atmosphere;
fungal infection, which affects the tree;
common mold, formed due to lack of ventilation and improper installation;
Pests different kind – small insects and rodents.

Of course, over time, the lining made of wood will dry out, which can lead to deformation. Therefore, it would be ideal if the processing and painting of the finish is performed immediately after its installation.

Attention: When buying material, take it only after checking it for moisture. It should not be higher than 12 percent.

Painting lining on the points

How to paint the lining outside the house, we will understand below. But any coating must be applied to a properly prepared surface, otherwise it will not last long. The preparation system is the same for all dyes.

Let's look at the preparation in more detail:

It is best, of course, to paint the lining that was installed outside immediately. But in practice, this is not often seen. Be sure to take into account temporary factors, and in some cases, poor quality of the previous painting.
Paint that peels off in tatters, a surface that is too dry, areas affected by rot - all this can often be found on the outside on walls where the painting was carried out poorly or not at all.

Therefore, before moving on to painting, the lining is processed. The work will not cause difficulties and is done by hand, but it will take a lot of time.

It is necessary to carry out the following steps:

Cleansing. We walk along the surface with a brush, if there are areas destroyed by decay - with a scraper. Remove all dirt and dust. If present old paint, we remove it especially carefully (see). After that, wash the surface with a solution of soda with a high concentration - ten liters hot water about 0.3 kilograms of soda;
Destroyed areas should be replaced with new lining strips;
Separately, it is worth highlighting the moment of fighting mold. To do this, there is a huge selection of special tools that process the walls outside the building;
For high-quality paint adhesion, the surface can be additionally degreased by using detergent, in which alkali is present;
We perform grinding;
We prime with special compounds(see), which do not allow mold, fungus and bacteria to develop, this step can be skipped. But if you want the coating to be durable, then this procedure is still better to do. Then the paint will lay down better, and the coating will turn out to be resistant and of sufficient quality.

Only after all the activities have been carried out, you can paint the surface or cover it with different compositions. Which specific wall treatment option to choose is up to the owner to decide, based on their preferences. Paint for wall paneling for outdoor use is quite different, here the choice is yours.

Antiseptics

One of the most functional and modern methods processing wooden lining outside are considered special impregnations. They do not allow bacteria to multiply, which prevents rot and the appearance of a blue tint on the tree.

Impregnations also have the following characteristics:

We apply an antiseptic

The impact on wood is not superficial, but volumetric. Impregnations get inside the lining by a couple of millimeters;
Many compounds protect the surface from ultraviolet rays, which has a positive effect on the appearance of the lining;
Protection is achieved from excessive loss or penetration of moisture, the finish on the outside will not dry out and become damp even with a significant amount of precipitation.

Depending on the type of impregnation, you can solve several problems at once.

For example:

Paint translucent or transparent formulations stands in the case when the plans include the preservation of the original pattern and structure of the tree. You can show the desired color or change it altogether. Thus, it is possible to preserve the natural beauty of the material and achieve an artistic effect;
An opaque coating helps to completely hide the existing imperfections, while maintaining the relief. This good way paint in such a way as to hide the destroyed areas that have been replaced with clapboard with a different texture, mask all imperfections, knots, and so on;
Impregnations that have tinting and antiseptic properties are extremely effective, but they also cost a lot. In addition, painting with such compounds will require more composition due to absorption.

Oil based paints

This dye is most often used to coat wood. But this is probably not the best option.

Let's see what makes it attractive:

Applying oil paint

Absorbed into the base, which guarantees protection against moisture ingress;
Resistant to temperature and humidity changes.

But even in this case, there are drawbacks, which often do not belong to the essential, rather, to the category of natural:

The composition dries for a long time - from eight hours to several days. Therefore, contamination and adhering midges are possible. Plus, there is a risk of precipitation and surface changes due to moisture;
The surface of the paint becomes matte over time, the color begins to change. This is especially noticeable in the extreme segments - light and dark color shades.

But if we consider oil paints in general, they are quite functional. They are cheap, do not require special application, retain their characteristics for a long time, and almost everyone can paint with standard options.

Acrylate based paints

It's over modern version but it costs a lot. Despite this, it provides useful features. For example, due to vapor permeability, varnishes and paints are best used on fresh lining.

Acrylic paints have the following features:

They retain their color for a long time;
Resistant to the effects of atmospheric phenomena;
Vapor permeable;
The coating is elastic, so there is a possibility of cracking from frost or heat.

Such compositions comply with environmental requirements, so they can be used to work outside the building, as well as to paint the room inside.

Alkyd varnishes

Although alkyd-based varnishes have good user characteristics, they are not used very often. This is due to the need to have experience in carrying out work, so that the surface in the end turns out to be neat and beautiful.

If you have the knowledge, then such compositions provide:

flat surface;
Good level of protection against moisture;
Strength;
Color stability over time.

If the coating was made with high quality, then it can last about ten years. After that, the varnish will collapse, and the process of removing it for another painting will take a lot of effort.

More about painting

to the most common and simple options painting include stain treatment. With its help, it is possible to achieve protection from adverse factors, as well as to create bizarre artistic effects.

Among other things, today a wide range of colors is sold, so this option can be safely compared with the use of translucent color impregnations. This method is usually referred to as the cheapest and simplest, but there is also a significant drawback here - the coating will not last too long. The appearance of the walls from the outside will have to be updated once every few years.
How could you understand high-quality painting finishing is available and without problems is carried out with due care and diligence. Modern compounds help to provide different protection characteristics, and there is a huge selection of color shades on the market.

In any case, for painting lining, the main factor in durability is the preparation of the plane. It depends on the appearance and durability. Therefore, do not neglect this question and the instruction will help you not to miss anything.

Everyone who used wooden material, for example, lining, in the lining of their house or bath, had to decide on the advisability of painting it in different colors or coatings with a certain composition.

If the decision was made that the distillation coating should be, then the next difficulty is the definition of a specific means for painting. Therefore, you should familiarize yourself with the proposed materials and the subtleties of their application in more detail.

Why is it painted?

First of all, what comes to mind for those who have a question about the need to paint the wall paneling indoors - is it worth doing this at all? All available pros and cons of such an event will help clarify the situation.

Coated wood:

Without cover:

If the cladding material was used not too expensive, then you can periodically replace it, because wood processing products are not cheap.
Those who like the color of old wood may not resort to using wood finishes.

Means for processing

As for the funds themselves, which are used to process the lining inside the premises, they have division into types depending on the functions performed and the available properties:

Protective action

Compositions necessary to preserve the integrity of the wood structure, which is violated by insects, fungi, decay processes, and also prevent drying. Usually it is a primer or impregnation.

Features to consider when choosing decorative coating:

Color.

This feature of paint or varnish is selected depending on the interior of the room. Interior design can be selected from a photo on the Internet.

Using the pigmentation of the product, you can make the zoning of the room or visually expand the space by using light colors in the painting.

And you can choose a composition without pigment, which emphasize the wood texture.

Compound.

For many, the components are very important composition chemicals , namely the absence of those that are harmful to the body.

All paints or varnishes that have the prefix "bio" do not pose a danger to humans. They are used for indoor coverage.

Manufacturer.

It is worth paying attention to such a criterion in order not to overpay "for the brand". There are many options for paints and varnishes produced in the Russian Federation, which are not inferior in quality to European ones.

How to process the lining?

Another nuance that cannot be circumvented, determined in the means for painting the lining inside the room - this is the place to paint. In order not to be mistaken in the parameters of the selected processing agent, you should know the features of the choice for rooms of different types.

Bath or steam room

Due to the fact that the temperature regime in this room is always elevated, painting its walls should be abandoned.

It is only necessary to treat the walls with a composition that will provide protection to the lining. Such means include wax varnishes. It is also worth knowing that the application in the sauna itself of the substance should be carried out in a single layer, in the dressing room it can be processed in two or three layers.

Balcony

Given that the open space of a balcony or veranda is exposed to various environmental factors, it should be initially applied to the lining primer, then paint or varnish.

Inside the house

The first requirement for the chosen means for processing in such a place is the degree of environmental friendliness, you should choose the most environmentally friendly means.

The processing process itself depends on the chosen means, but it is desirable to carry out in several layers, especially if it is paint or pigmented varnish.

Interior Design Examples with painted lining:

Coloring steps:

The application of any paintwork is carried out under conditions temperature regime within 5-30 degrees above zero.

This parameter can be changed by the manufacturer, which will be indicated on the packaging. If the temperature is lower than the specified one, then this promises freezing of the composition, and if it is too high, then the applied coating may dry out in uneven fragments.

Movement during painting should be from top to bottom.
It is desirable to dilute the paint before application to a more liquid consistency, like milk.

This will allow you to apply thin layers paint, will significantly save time, effort and paint consumption, as well as speed up drying.

The part of the lining that does not need to be painted is recommended to be pasted over with masking tape.

Those places that are located near the adhesive tape are best painted over using fine brush, while using minimal amount facilities. So you can be sure that the composition will not fall under the adhesive tape and the surface to be painted will be even at the edges.

Painting lining with wax and oil - watch the video:

More recently it seemed that natural wood, as finishing material, has sunk into oblivion. But quickly satiated plastic panels and a variety of tiles, many have come to the conclusion that best solution is eco-friendly wood. This is especially true for private country houses, where you want to be in unity with nature, not only outside the home, but also indoors. However natural material needs additional processing. Therefore, more and more often the question arises of how to paint the lining inside the house in the country.

Indeed, why additionally process products that have excellent decorative look. But there are several reasons that say that this procedure is simply necessary.

The staining process is divided into two important components: protective and decorative. In the first case, it is necessary to process the material to strengthen its properties, in the second - to give a better decorative look.

Painting lining is a procedure that has not only a decorative, but a protective function.

Let us consider in more detail the purpose of each of the compositions:

The application of flame retardants reduces the flammability of the elements. It is important to understand that it is impossible to completely eliminate the spread of flame.
Additional treatment with antiseptics is carried out to protect against the appearance of mold and fungi, which leads to damage to the material.
Waxing and varnishing are dual-use options. On the one hand, they protect the surface from various damages, and on the other hand, they emphasize the decorative appearance of the product.
Paint work involves concealment natural color tree. This does not mean that the material will lose its appeal. On the contrary, it is possible to diversify the interior, while maintaining the texture of wood.

On a note! Raw elements have a shorter service life, which is sometimes 5-6 years, and even less in the country.

Lining processing various formulations allow you to extend the life of the material

Types of materials for painting

How to paint the lining? It is quite difficult to answer this question. The fact is that there are many compositions that differ in their characteristics. Their correct use can transform the room or, conversely, spoil the whole appearance.

Protective compounds

These solutions act as protectors, but can give a certain decorative effect.

flame retardants

It is necessary to cover such compositions with products that are in places where a fire can occur. Of course it's better to soak everything wooden materials used in finishing work.

On a note! It is very difficult to apply fire retardants with your own hands, the effect is not so significant. Therefore, preference should be given to elements that are processed in production.

Antiseptics

Substances that eliminate the threat of the appearance various kinds bacteria that promote decay and decay. This solution is great when you want to leave the material unchanged. The composition will protect the product for a long time, so that it will not need additional staining.

Antiseptic protects lining from various bacteria

Lucky

In fact, varnishes are already closer to colorful compositions, but they carry a good protective function. Painting lining inside the house can be done with different materials:

Acrylic lacquer. Great for everyone interior spaces. It is transparent and translucent. If necessary, the substances can be tinted.
Synthetic materials. This option requires caution. At the dachas, they cover the premises that are located at the entrance to the house.

Lacquer compositions are quite easy to work with, you just need to take into account that in order to achieve a better result, you need to apply them in several layers.

Varnish allows you to protect the lining from rotting, damage and destruction

On a note! An excellent solution can be wax, which protects the elements and gives them a rich shade. But applying it is quite difficult, because you have to literally rub it into the surface.

Decorative options

Lining paint is The best way to transform a surface that has already served for a considerable period of time. That is, if over time the product began to darken, cracks appeared in places. In this case, it is best to apply paint. As a result, you can completely update the interior of the cottage in the country and bring to life ideas that will help this.

Painting lining - one of the the best options protection, which also performs a decorative function

How to cover the lining? It should be borne in mind that for work can be used different types material.

Oil paint

It is considered one of the most popular substances. This option has been used for many decades. This is because the solution has excellent characteristics. They lie in the fact that the composition penetrates deep enough into the upper layers of wood, ensuring its long-term preservation. The coating retains its properties for 7-10 years.

Some disadvantages cannot be ruled out:

The material has a rich chemical smell that disappears for a very long time.
The first point leads to the fact that it limits the staining time. That is, it is not possible to work in the winter, because thorough ventilation is required, which can defrost the entire country house.
The protective property of the paint is fraught with another drawback - the material firmly clogs the pores of the tree, it stops breathing. This means that the microclimate, which is especially valuable when using lining, will be spoiled.

Therefore, for internal work, this composition is used extremely rarely.

It should immediately be noted that this type is very similar to acrylic compositions, but has a lower price and the necessary characteristics.

Such a coloring option has the following properties:

Absent bad smell which needs long ventilation.
The coating is much more elastic, which increases the service life. It more successfully resists the aggressive external environment. This is very important because many country houses remain unheated for the winter.
The surface remains breathable, which allows you to maintain the exact atmosphere that is inherent in wooden structures.
Work is done much faster and easier.

Acrylic paint allows you to create a flexible, breathable coating

Of course, such material costs a little more than oil paint, but the result exceeds all expectations.

On a note! To paint the walls from the inside of the house, other options are also used, which contain a note on the label - “for woodworking”. One of these varieties is stain. This is an excellent composition that allows you to saturate the tree with depth, but retain its color and texture.

How staining is done

How to paint the lining so that the effect is long and impressive? For such an event, you will need a set of tools:

Set of brushes and roller. If possible, then the spray gun.
Tray. To make it easier to pick up paint.
Protective and decorative compositions.
Sandpaper, hard brush.
It is better to provide a stable stepladder and goggles to protect your eyes.

The use of an airbrush allows you to quickly complete the work on painting the lining

Coloring consists of several stages. Much more difficult when the work is done on the old coating. Then it becomes necessary to remove the old decorative layer and clean the surface well.

Stage one - preparation

Purchased products are checked for possible damage and deformation. It often happens that materials are bought that belong to a lower class. They demand long preparation- being processed sandpaper, cracks are covered with putty on wood. If they meet on the surface dark spots, then bleaching is performed.

On a note! You need to be careful about the presence of knots. Sometimes it seems that these inclusions give a certain charm to the material, but they can cause defects.

If the material has defects in the form of cracks, then they are eliminated with putty

Stage two - primer

Need to cover front side lining with priming compounds. This will reduce the consumption of other solutions, increase adhesion, and will also prevent the elements from being deformed. Wherein Special attention given to knots, they are literally impregnated to exclude the possibility of falling out if drying occurs.

The primer improves adhesion when painting lining

Stage three - impregnation

Now apply protective impregnations. These are flame retardants and antiseptics. Impregnation is carried out over the entire surface. We must not allow unpainted places to remain. It is important to consider that such products should not have extraneous (pungent) odors and change the color of the tree.

On a note! Many mistakenly believe that it is possible to exclude the process of applying an antiseptic if you purchase a primer that already includes this substance. First, the content of such components in the primer is negligible. Secondly, careful processing is necessary for giving.

When applying protective impregnation, it is necessary to ensure that there are no untreated areas

Stage four - coloring

How to paint lining inside the house? This procedure begins only after the material dries well from previous manipulations. The process is:

The paint is prepared in advance. The solution must be well placed, because at the bottom there may be a sediment, which includes the main components.
A small part of the composition is poured into the tray if a roller is used. For a brush, it is better to provide a container that is easy to carry with you. The use of an airbrush makes the work better, and the paint is poured into a special container.
It should be borne in mind that the movements are performed along the fibers of the material. You can not linger in one place, the coverage should be uniform.
Several layers are applied, this will provide an excellent decorative effect.

To get good decorative effect, the paint should be applied in several layers

On a note! Each subsequent layer is applied only when the previous one dries. It is better to resist the temptation to apply one, but a very thick layer. This will lead to the fact that the coating will begin to peel off, while the view will be completely unpresentable.

Still, how to cover the lining? This question is quite complex, the answer to it depends on many factors that are calculated purely individually. But it must be borne in mind that if the composition is used over large areas, then it must necessarily provide "breathing" of the material.

Despite the inexorable development of technology and the spread of synthetic substitutes in construction, natural materials For decorative design houses continue to be in stable demand. In our article we will tell you how to paint the lining inside the house?

Clapboard - thin wood panel, which has many positive properties: thermal and sound insulation, ease of installation, pleasant appearance. But, like any tree, it is affected by moisture, the sun, insects or fungi. To combat these negative effects, painting is used.

How can I paint the lining inside the house

The choice of one or another paint depends entirely on your preferences and requirements. Someone needs a hypoallergenic coating, for others, the speed of its drying is important. There are many paints and varnishes that can be used to paint the lining inside the house in white, beige, yellow or any other color:

Acrylate paint is harmless and dries very quickly. Its main disadvantage is the high price;
oil paint - dries for a long time and has a persistent odor, therefore it is suitable for painting only in the warm season;
decorative glaze - in addition to changing color, it perfectly emphasizes the wood structure;
alkyd varnishes;
stains are well suited for processing wood without flaws. After all, they do not paint over it, but only change the shade;
opaque enamels - are applied in three layers and completely paint over the original structure of the tree.

After reviewing the photo of painting the lining that is presented on our website, you can more clearly imagine the whole variety of existing paints for processing floors and walls inside the house.

Stages of painting lining

Before you start painting the lining inside the house in the country, it must be thoroughly cleaned and treated with fine sandpaper to eliminate possible roughness. If the board cannot be cleaned with a simple brush, special cleaners should be used. Result this stage- clean, white and smooth lining.
The primer is selected depending on the type of wood being processed. Apply by roller or sprayer. For indoor use, the primer must be water-based and free of a persistent and unpleasant odor.
Wood surface impregnation by special means necessary for additional protection lining from moisture, fungi and insects. High-quality impregnation should not emit pungent odors. After completing this stage of work, you need to let the lining dry for at least two days.
Painting stage. Best result achieved with a spray gun, but a roller or brush is fine too. The paint should be applied in a thin layer, so you should not repeatedly drive the brush over the same place. Usually the paint is applied in several layers. It all depends on the desired color and uniformity of the final coating.

In the video at the end of the article, you can take a closer look at the entire process of directly painting the lining inside the house.

Little paint tricks

Thanks to the feedback from our readers, here are some tricks that will come in handy when painting the lining inside the house:

paint on hands can be easily washed off vegetable oil. Apply it on your hand, hold for 5 minutes and wash off with soap;
To clean glass from paint, use a paste that consists of chalk and concentrated soda. Apply the paste to the paint, let it stand for a while and boldly remove it;
old oil paint can be easily removed with foil and an iron. Iron the painted section of the wall with a hot iron through the foil. Then the paint can be easily removed with a spatula.
