For repair work indoors, they were used even when there was a shortage of building materials on the market. But even today, in a period of sufficient choice, the demand for such material remains. How to apply oil paint? What staining technologies exist? What is the difference between oil paint and other compositions? More on this later in the article.
Inexpensive do-it-yourself repairs: painting walls with oil paint
Drying oil - the basis of oil paint - is produced synthetically, which reduces the cost of finished products, while its qualities remain the same: the paint fits tightly on the surface, does not allow moisture to pass through, and is resistant to abrasion.
How to paint walls with oil paints
The main problem faced by a person who paints walls with enamel or oil is an unpleasant, persistent odor that literally eats into clothes, skin and hair. In addition, the substances released during evaporation and drying are toxic.
Wait until the first one dries before applying the second layer. If you paint over a seized, but not dried layer, then the surface will be with stains, smudges and bumps.
Coloring technology
Wall painting technologies depend on the following points:
- wall dimensions, height and width;
- the presence of a previous layer of paint;
- wall material (concrete, slab, drywall, wood);
- room temperature;
- desired structure;
- composition viscosity.
If you need to repaint the walls on top of the existing one, then you need to sand the surface, close up the openings and irregularities with putty, then soak it with a primer.
For a structurally rough surface, a roller with a long and dense fleecy synthetic base is required. After one application, the surface will be uneven, with small protrusions and droplets. As a rule, this technology is used instead of putty with a relief base.
For a perfectly smooth surface with a brilliant effect, it is necessary to initially level the surface, free the wall from bumps, old plaster and paint.
After priming, use the spray gun method.
The technology of painting walls with a brush is not used due to the fact that on a flat surface, after a while, the paint flows down even with a thin layer, stains and unevenly painted areas are obtained.
The brush helps in hard-to-reach places:
- corners;
- ceiling-mounted area near the baguettes;
- corner area near the window and doorway;
- skirting area.
Painting the walls begins with painting the corners, then use a roller with a pile of no more than 4 mm, 150-200 mm wide.
Nuances at work
In addition to a roller, brush or spray gun, you will need:
- masking tape for protection and even application of paint in the corners, on window slopes;
- a tray for distributing paint and limiting the amount of material taken per roller;
- sandpaper to eliminate bumps, sagging of hardened old paint;
- floor film;
- drying oil to control the density of the mixture.
When using an airbrush, it is necessary to test this technology in advance on a small area in order to understand the process and evaluate the final layer thickness on the wall. If the oil composition is very thick, it is worth diluting it with drying oil so that the pigment lies evenly.
Painting with oil paint: how is it different from others
The main difference between repair work with an oil composition is a persistent smell. Intoxication of the body when safety rules are neglected can be severe, hospitalization will be required. However, it is worth remembering that the first signs are extremely difficult to recognize, headache, nausea and vomiting are already complications of chemical poisoning.
It is also important to remember that oil paint fades, peels and burns over time. Therefore, when choosing a material for painting walls, you should pay attention to the availability of light, distance from hot household items. With constant thermal contact, it will burst, peel off and fall off the wall.
Today, oil paint for painting walls or ceilings is used extremely rarely. More often, this composition is used for outdoor work or for painting floors. In any case, you should follow the safety rules: ventilate the room and use respirators.

Painting walls with oil paint is a good way to protect and decorate the surface, however, in recent times this material is increasingly called outdated and too harmful, wondering how to paint walls with water-based paint over oil.
We will try to answer these questions and tell you as much as possible about this material, as well as show how it is applied correctly.
Oil paints
Composition and features
From the name of the material, you can guess that it is based on oil. Previously, natural oils were used to prepare paints, today it is too expensive, and combined and synthetic drying oils, as well as alkyd resins, are used as part of the coating.
These drying oils contain suspensions of pigments and fillers, which, most often, are finely ground inorganic powders of various oxides and salts, as well as mineral rocks and additives.
To dilute the paint and give it the necessary consistency, volatile organic solvents are used:
- White Spirit,
- toluene,
- acetone,
- turpentine,
- xylene and others.
In the photo - powders of various pigments.
Important!
When natural or synthetic drying oil comes into contact with air, oxidative polymerization is observed and the substance begins to harden, a film forms on its surface and gradually the material becomes solid.
This effect is taken as the basic principle of oil paint as a decorative and protective coating.
Pigments allow you to achieve the desired shade and color the mixture in different tones. They are organic and inorganic, but organic ones are practically not used for the preparation of oil formulations.
Minerals can be divided into two main groups:
- Achromatic. Used to obtain white, black and gray colors. It can be zinc, titanium or lead white, lithopon, graphite powder, black, carbon black or soot, brass, bronze or aluminum powder;
- Chromatic. Used to obtain various colors of the rainbow and their shades. They are divided into iron oxide, lead and others, most often they use iron metahydroxide and trivalent iron oxide, iron red lead, litharge, red lead, various crowns, as well as mixtures of oxides and salts of chromium, cadmium, cobalt and other metals.
Since we are dealing with a suspension of insoluble particles in oil, the composition must be mixed before use, because particles of pigments and fillers eventually fall to the bottom of the solution.
If the paint is not mixed, then the higher layers will be less saturated, while the bottom will have a very thick and bright paint. This will cause areas with different color intensities to appear on the wall when applied, which does not look good.
The solution is applied with a brush, roller or sprayer. The greatest consumption is observed when working with a brush, but this method allows you to paint over the surface more thoroughly, especially when it is loose, porous, embossed or complex.
- "spray gun",
- airbrush,
- spray.
Surface preparation and priming is required before applying oil paint. This is true for all finishes. It can be applied to old paint, provided that it is also oily and adheres well to the surface.
It is possible to cover metal, wood, brick, stone, concrete and plastered surfaces. The material is best used for outdoor use, and interior finishes based on organic solvents and lead should be limited.
In addition to toxicity, allergenic and carcinogenic activity, oil coatings have another property undesirable for residential premises: they do not let steam through. The walls covered with such paint cease to breathe and maintain the natural humidity in the room, which leads to a deterioration in the microclimate.
Important!
The use of an oily material inside the living space is justified only when vapor tightness is desired: in bathrooms, basements, open balconies, toilets, etc.
We do not recommend using oil paint to open walls in bedrooms, living rooms, glazed loggias and other residential areas. Previously, this was justified by the lack of an alternative, but today there are a lot of compositions more suitable for such purposes.
The point here is not only the smell, there are odorless oil coatings, and after a good drying, the solvent disappears.
However, a tiny amount of solvent remains inside the layer, which continues to enter the atmosphere. It is safe from the point of view of poisoning, but can provoke allergic reactions and the growth of cancer cells in people who are sensitive to these substances.
Important!
Work with the coating should be in protective clothing, a respirator and goggles, especially indoors.
Be sure to ensure a constant supply of fresh air, otherwise it will be dangerous to be indoors.
If you experience symptoms of illness or intoxication during the application of oil paint, immediately leave the work area.
Recently, oil compositions have been most often used for painting ferrous metal products, especially those that are on the street: sports equipment, gas and water pipes, elements of urban infrastructure, etc.
This material is also widely used for coating wooden products:
- shops,
- pavilions,
- windows,
- doors,
- and window sills.
With the use of zinc powder, you can create an excellent means of anti-corrosion protection (Zinga conductive paint), and the use of special additives allows you to create fire-retardant paints for Polysteel metal.
Important!
The use of oil coatings for coating children's rooms, bedrooms and living rooms is considered unacceptable by modern standards, but for outdoor work, coatings for public areas, protection of metal and wooden surfaces, such materials are quite suitable.
Advantages and disadvantages
This is a rather hackneyed topic, but in most publications there is a clear bias in favor of the disadvantages of oil paint. This is most likely due to marketing policy, and we will not go into its wilds.
Of course, any material has drawbacks, but when it comes to oil coatings, for some reason everyone cites entrances painted with terrible gray-green paint, forgetting that these entrances have been painted for a long time, and painted with Soviet paint.
Without a doubt, modern materials from the world's leading manufacturers, and for the most part this applies to domestic ones, have nothing in common, except for the name, with the coating of old entrances.
Modern materials have a basic set of shortcomings, but their importance should not be exaggerated:
- The presence in the composition of the mixture of toxic solvents - volatile organic compounds that actively evaporate at room temperatures and poison the surrounding atmosphere. Here it must be said that after three to four days, almost all the solvent disappears, and the toxicological hazard disappears, but the likelihood of allergic reactions and carcinogenic activity remains;
- Zero vapor permeability. This quality in some cases becomes a serious drawback, because the walls of residential premises painted with such a composition cease to maintain normal gas exchange and acceptable humidity, which adversely affects the microclimate of the room;
- Insufficient elasticity. Often, oil formulations do not cope well with thermal expansion and other changes in the geometry of the base on which they are applied, which leads to cracking of the coating. Products of well-known manufacturers with a good reputation, as a rule, do not have this drawback.
You can also name a number of advantages of this coverage:
- Versatility. The material can be used on various substrates: metal, wood, stone, concrete, plaster. It is also used for outdoor and indoor work;
- Durability and wear resistance. The coating is sufficiently durable, resistant to abrasion, impact and other mechanical influences;
- Moisture resistance. The paint is not afraid and does not let in moisture, which has become one of the main arguments for using it to cover metal parts, facades and other open structures and their parts;
- Simple care. The coating is easy to clean, is not afraid of household chemicals, is not erased or washed off with rags and other cleaning products;
- Good adhesion. Oil paint adheres well to the surface, and if applied correctly can last a long time;
- Affordable price and good coverage. You can get acquainted with the norms of costs and expenses using the table GESN 15-04-025-8 “Improved painting with oil compositions for wall plastering”.
Important!
You should soberly and without emotions evaluate the merits and demerits of any material, and you will find that in your field it is quite in demand and applicable.
Application
For those who are not afraid to work with their hands, our traditional instruction:
- Coating surface. If oil paint is applied, then it can be left, provided that it adheres well to the surface. You can remove the coating with a solvent, blowtorch or hair dryer, as well as with a metal brush and chisel;
- If the plaster is old and has flaws, it should be impregnated with a layer of drying oil and then puttied. After that, the surface should be sanded with sandpaper;
- We sweep dust from the wall and apply a layer of primer. To do this, you can purchase a ready-made composition or dilute the paint with drying oil to a liquid consistency and shade with a brush over the surface;
- After the primer dries, apply the main coating with a brush or roller in a thin layer, after which the procedure is repeated. It is impossible to apply the material in one thick layer, as waves and streaks will occur.
Advice!
Most often it is enough to apply two coats of coating, if this is not enough, then a third can be applied.
Doing more than three layers does not make practical sense.
Output
Oil paints continue to be actively produced and used, despite serious competition and a number of shortcomings. In their field, these materials have shown themselves well and are quite worthy of further use. With the help of the instructions and video in this article, you can do the painting work yourself.
In modern repair, the use of interior paint for walls and ceilings is common. The compositions that were used before have long been replaced by new ones, now covering the walls with paint is a durable and reliable way of finishing. But in order for the wall painting to live up to expectations, it is important to choose the right interior paint. It is not enough to choose the color of the coating in order for the paint to hold and last for many years, it is necessary to choose the appropriate type of interior paint depending on the material of the coating.
Classification of interior paint
Paint for walls and ceilings is divided into 3 main types. The rest of the options that you will meet in the hardware store are derived from these paints.
- Oil paint for walls and ceilings. The basis of oil paint is drying oil. The disadvantage of oil paint is a long drying time. In addition, the paint smells strongly, for the time of staining and until it dries completely, it is necessary to free the room from people and animals. The advantage of oil paint is its low cost.
- Alkyd paint for walls and ceilings. Alkyd paint contains synthetic resins. Forming a film on the substrate, this paint is resistant to moisture and UV rays.
- Water-dispersion paint for walls and ceilings. Water-based paint contains water instead of a solvent. Non-toxic, breathable paint, but not resistant to moisture. To eliminate this problem, acrylic is added to the composition of the water emulsion.
How to choose interior paint
The choice of interior paint depends on the substrate to be painted.
- For painting wooden surfaces, use oil or alkyd paint. The water contained in water-based paint will harm the tree. Don't forget to pre-treat the wood, but finish painting with a protective varnish.
- If the walls of the apartment are prepared for painting by leveling with concrete or plaster, water-based paint is suitable. But it is better to cover the same base when painting walls in a bathroom or kitchen with alkyd paint, it interacts better with water.
- For the ceiling, the type of paint is unimportant, but for the convenience of painting the ceiling, purchase a thixotropic paint (it can be of all kinds). Its peculiarity lies in its density. When stirring, the paint becomes liquid, but as soon as you stop stirring, the solution thickens to a state of sour cream. This is convenient for working with a horizontal ceiling surface. But for walls, it should not be chosen: ordinary paint spreads itself under the influence of gravity, unlike thixotropic, which will have to be carefully distributed.
- Working with a metal surface is similar to working with wood. Metal also does not like water, so oil or alkyd paint is suitable in this case.
Difficulties arise when there is already a coating on the walls and ceiling, and it is impossible to determine its composition. In this case, it remains only to completely get rid of the old paint, and only after that apply a layer of new one.
How to apply interior paint
Painting the walls and ceiling is just the final step. Before you get the brush, you will have to do the main part of the work, prepare the base for painting. There are several key steps:
- Removal of the old coating, if the repair is not the first time.
- Wall alignment. For large level differences, use cement mortar.
- Applying a primer. The primer performs several functions. It enhances the adhesion of materials, and also reduces the amount of paint wasted. Without a primer, the first layer of paint will soak into the wall without leaving a trace. Match the primer to the paint - acrylic primer to acrylic paint, for example.
- Fix foundation flaws. Use putty to repair cracks in walls and ceilings.
- If necessary, treat the walls with an antifungal and antiseptic solution.
- Paint the finished walls and ceiling using the appropriate painting technique. Wait for each layer to dry before applying a new one.
Painting walls and ceilings with your own hands is not a difficult job, but it is creative and requires patience. Do not rush, wait for each layer to dry, then the coating will please the eye for a long time and look like freshly painted.
There are many types of paints for, among them oil is very popular. It has excellent qualities, thanks to which the coating will be protected from the negative influence of external factors.
There was a time when oil paint for walls was forgotten a bit, after other, improved options began to appear on the market: enamel, acrylic, water-dispersion, latex and acrylic. They even began to say that oil paint is toxic and should not be used.
Let's try to figure out if this is really the case.
Components
The basis of its production is oil. Previously, the paint was made from natural ingredients, but now everyone is trying to reduce the cost, while receiving the same income from sales. Now, for the production of oil paint for walls and ceilings, they use synthetic or combined, as well as alkyd resin. Drying oil, in turn, is filled with a suspension and pigments from a ground fine powder of inorganic nature from oxides, mineral additives, and salts.
Thinners
As thinners for oil paint use:
Note
In the process of the reaction of drying oil with oxygen, the substance solidifies due to oxidative polymerization. A film forms on the paint, and the composition acquires density. It is this reaction that is the fundamental principle of creating a protective layer on the decorated surface.
Adding various pigments to drying oil allows you to get the desired colors of oil paint at the output. These additives may be of inorganic or organic origin. But for the production of oil products, organic substances are almost never used.
Kinds
The mineral components themselves in the composition of the paint are divided into 2 groups:
- Chromatic - used to obtain iridescent shades and the like. The composition has colorful shades that are pleasing to the eye. For this purpose, use: cobalt and chromium salts, litharge, red lead, cadmium salts. Pigments used: chromium and cobalt salts, iron, litharge, cadmium salts, metahydroxide.
- Achromatic - used to obtain shades of gray, white and black. Titanium, lead, zinc, lithopon, black, aluminum or bronze powder, carbon, soot are suitable for this purpose.
Considering that oil paint for outdoor use is a suspension of insoluble components, in order to obtain a homogeneous mass, it must be thoroughly mixed before applying the composition to the walls. And it is necessary to carry out this procedure from time to time in the process of work, since the particles tend to settle at the bottom of the can. Otherwise, in the top layer, from which you will take the paint, there will be few pigments, and the bottom layer will turn out to be concentrated. As a result, the painted surface will acquire an uneven shade.
Features of painting walls with oil paint
Before you get started, prepare the tools:
- Regular paint brush;
- Roller with a container for paint;
- Spray gun or spray gun.
Paint consumption
Previously, it was often used because there was no alternative. Now, there are many other, more environmentally friendly and safe formulations without solvents and unpleasant odors. When working with oil paint, do not forget about respiratory, eye and skin protection.
Also, leave windows and doors open to allow fresh air in.
Achromatic oil paints
Very often used for the purpose of coloring ferrous metal products. These are gas and water pipes, sports equipment, individual elements of the city's infrastructure. In addition, the material is suitable for finishing wood products: windows, window sills, doors, gazebos, benches.
Advantages and disadvantages of oil paint for walls
Oil paint for outdoor use is a rather controversial material that has its fans and haters. The same can be said about almost any material, each has its pros and cons. For some surfaces, one material is suitable, for others, a completely different one.
It is worth starting with the disadvantages of oil paint:

Results
If you do not take into account the disadvantages of oil-based paint, then it can be an excellent choice for those who are ready to turn them into virtues. In addition, the affordability of the price of the material allows you not to lose your position in the market of paints and varnishes.
