Any kind of work on the interior decoration of the premises, which is associated with painting wooden surfaces with oil paints, cannot do without the use of drying oil. Even despite the recent emergence of new, more advanced formulations that perform the same tasks. What is drying oil? Why is it needed and how to use it correctly? - these are the questions, the answers to which will help to get a perfectly painted surface.

Drying oil types

At the moment, it is customary for experts to distinguish three types of drying oil: natural drying oil, drying oil "Oksol" and composite drying oil.

natural drying oil

Natural drying oil, the quality of which is strictly regulated by GOST 7931-76, consists of 97% vegetable oil of natural origin (linseed or sunflower), which has undergone special heat treatment, and 3% of desiccant.

1. Such drying oil reliably protects wood, however, it can only be used indoors.
2. In addition, natural drying oil has a fairly high cost by today's standards.

Drying oil "Oksol"

Drying oil "Oksol", the qualitative composition of which must comply with GOST 190-78, is a substance that has a slight odor and consists of 55% vegetable oil (linseed or sunflower), 49% white spirit and 5% desiccant.

1. "Oksol", on a par with natural drying oil, perfectly copes with its main task, namely, it protects wooden surfaces, forming a dense film that is resistant to water, which does not blacken for a long time.
2. At the same time, Oxol drying oil is much cheaper than natural drying oil and, unlike the latter, can even be used to treat any surface outside the building.
3. The best is the Oksol drying oil, which has linseed oil in its composition, so it costs a little more than the one made on the basis of sunflower oil.

Composite drying oil

Composite drying oil is the cheapest drying oil with a characteristic pungent odor. It does not have a GOST number, so the composition of such a substance is not regulated at the legislative level, and production is carried out exclusively according to technical specifications.

1. Composite drying oils, as a rule, contain various chemical components, in particular, products of the petrochemical industry that are harmful and toxic to the human body (for example, petroleum polymer resins).
2. Therefore, such compositions are strictly prohibited for indoor use.
3. The smell of composite drying oil remains for a long time even with good ventilation in the room. this is the cheapest drying oil with a characteristic pungent odor.

Features of the use of drying oil "Oksol"

Drying oil "Oksol" is a quick-drying substance that has an increased hardness and forms a glossy coating on the surface of the material processed by it. It penetrates well into the pores of the tree, thereby emphasizing its structure.

• Drying oil "Oksol" is for sale in containers of various capacities, completely ready for use.
• It is necessary to apply such a substance on a dry surface, which, if necessary, is sanded in advance and thoroughly cleaned of dust or grease. Only after that do they move on to polishing.
• First, the composition is well mixed, if the drying oil has thickened during storage, it can be diluted with white spirit, nefras, and also, if desired, a solvent for varnishes and paints (oil and enamels).
• The drying oil is applied in a thin layer with a brush or a special roller. At the same time, all work must be carried out in a room that is well ventilated with an air temperature of at least 15 degrees Celsius and a relative humidity of 80%.

• The drying time of drying oil "Oksol" is approximately 24 hours, so the interval between each subsequent layer should be approximately a day.
• The rest of the unused drying oil can be stored for a year in a tightly closed container. For this, a dark, dry place inaccessible to children is suitable.
• To protect your hands during the polishing process, it is recommended to use rubber gloves. It is also important to avoid getting drying oil in the eyes. If drying oil has got on open areas of the body, then they are cleaned with rags or a rag soaked in vegetable oil. Then thoroughly wash everything with warm soapy water.
• With the help of drying oil "Oksol" it is also possible to putty small cracks by mixing it with sawdust until a thick homogeneous mixture is obtained.
• All work to avoid fire hazards must be carried out away from sources of open flame.

Subject to all the recommendations, the work on polishing is quite simple, so almost anyone can do it. To learn more about the process of professional wood processing, you can watch the following video: [

Drying oils provide excellent protection of wood products from insects, mold and fungus, atmospheric precipitation. In the article we will talk about the classification of such compositions and their features, and also describe in detail one of their most popular varieties.

The compositions of interest to us are made from various oils, to which solvents and desiccants are added - compounds that include strontium, lead, iron, lithium, cobalt, and other chemicals. elements. All drying oils are divided into:

• natural;
• alkyd;
• combined;
• synthetic;
• semi-natural.

The natural composition of 97% consists of sunflower or linseed oils, which are subjected to heat treatment. The cost of such drying oils is high. Now they are rarely used. Usually they are used to dilute paints and varnishes. Any wooden surface can be treated with a natural composition, but on condition that they are indoors. Linen compositions are also used for the production of special lubricating pastes, putties, dilution of thick paints and fillers.

Semi-natural and combined drying oils have a more affordable cost. They differ from natural compounds in that volatile group solvents (for example, white spirit) are necessarily added to them. The most famous semi-natural composition is Oksol. We will consider it in the next section. Alkyd drying oils are made from solvent-diluted and oil-modified resins. And synthetic compositions, which are often called composite, are made from rubber processing products, materials from the oil and coal industries. They do not contain natural oils. Such drying oils are not used indoors due to their increased toxicity. The only plus of synthetic solutions is the low price.

Oksol - a composition with special characteristics

Drying oil Oksol belongs to the group of semi-natural compositions used for wood protection, production and dilution of paints (oil-based, thickened). Let's see what this composition is made of. It contains 55% natural oil, 40% solvent (in most cases - white spirit, less often - nefras or turpentine), 5% desiccant. The composition is produced according to GOST 190-78. More on its terms below.

Oksol is divided into two brands. The first - B, is made from hemp and linseed oil. This drying oil can be used for wood processing both indoors and outdoors. The second - PV, is made from soybean, camelina, sunflower, grape or corn oil. The composition is used exclusively for interior painting work. Nuance. Oils of both brands are not intended for application to floor surfaces.

Gosstandart 190–78 describes all the technical characteristics of Oksoli. Let's highlight the most important of them:

• acid indicator - up to 6 mg KOH / g (grade B); up to 8 (PV);
• drying period - 20-24 hours
• viscosity (conditional) - 19–25 s (PV), 18–22 (V).

Oxol is characterized by complete transparency, easy flammability and a pungent odor. The latter, after using drying oil, does not erode from the room for quite a long time. At factories, Oksol is packaged in metal containers (cans of different capacities) or plastic. Important! When opening metal containers, you should use a tool that does not allow a spark to appear (do not forget about the flammability of the composition). It is not allowed to use Oksoli near working heating equipment and sources of open fire. In case of ignition of the composition, it can be extinguished by any means (asbestos cloth, steam and chemical foam, gas, fine water).

Experts advise home craftsmen to use Oksol based on linseed oil. It dries completely in 20 hours and has a less unpleasant odor than drying oils from other technical oils.

True, the cost of linen compositions is slightly higher. At the same time, Oksol of any brand guarantees the receipt of a durable waterproof film on the treated surfaces that does not blacken for a long time.

The use of semi-natural drying oil - how to apply the composition?

Since Oksol has a pungent odor and belongs to the group of toxic oil compounds, we adhere to some mandatory rules when working with it. Firstly, we carry out the planned painting activities in a respirator, rubber gloves protecting hands and tight overalls. In this case, the risk of poisoning with drying oil vapors and getting drops of it on the skin is significantly reduced. If, nevertheless, Oxol has landed on human skin, you must immediately wipe it off with a clean rag. After that, thoroughly wash the damaged area with soapy water.

Secondly, work with drying oil indoors is allowed only on the condition that they have effectively functioning ventilation. Directly, the scheme for processing wooden structures by Oksol looks like this:

1. 1. We clean the product from the old coating (lacquer, paint, and so on). We remove greasy stains, dust, and other contaminants from the surface.
2. 2. Dry the cleaned structure. If there are significant roughnesses on its surface, we additionally grind the wood.
3. 3. Open a jar of Oksol. We mix the composition well. If a container is used from which the composition was taken earlier, add a little white spirit to the jar. Then we can easily stir the thickened mass.
4. 4. Using a brush or roller, apply drying oil to the product. We make the layer not very thick.
5. 5. We are waiting for 24 hours. Then we re-paint the product with Oksol. If it is necessary to apply the third layer, we again wait a day. And only after that we once again process the surface with the described composition.

GOST 190-78
This standard applies to drying oil "Oksol", obtained by oxidation of vegetable oils, followed by the introduction of a desiccant and dilution with white spirit.

Wood is very often used in construction and everyday life, but Oksol drying oil will help protect it from the destructive effects of insects and time. Let's get acquainted with the features of this composition, its characteristics and, of course, dwell on the practical part.

Purpose and principle of operation of drying oil

The principle of operation is that most oils, upon contact with oxygen, heat and light, thicken very intensively, and a thin layer completely hardens. This is due to fatty acid glycerides, because their amount and the degree of iodine number (an indicator of the number of double bonds in the carbon chain) are directly proportional to the rate of setting of the agent. Linen and hemp compositions of drying oil Oksol (GOST 190–78) are most effective, since the oils of these plants have 80% and 70% of glycerides of linoleic and linolenic acids, respectively, and the iodine number exceeds 150.

It should be noted that in its natural form, any vegetable oil freezes for quite a long time, and in order to accelerate this property, it is subjected to heat treatment. When heated, the hardening-retarding substances decompose, and salts provoke rapid oxidation. In addition, special compounds are introduced that contribute to its rapid drying (driers). As a result, the film deposited on the surface becomes solid within 6 to 36 hours.

Types of drying oils and their features

There are several varieties. Natural 97% consist of plant oils (sunflower or flax), the rest is occupied by a desiccant. Their main purpose is to dilute paints and treat wooden surfaces in rooms. Such drying oils are divided into oxidized and polymerized. The latter have a darker color, and products treated with it age faster.

Characteristics of drying oil Oksol (GOST 190–78) practically do not differ from natural. It is applied to internal and external works. But the composition also includes a solvent, which gives a pungent odor. Also, this type is cheaper than the previous one. Drying oil Oksol is produced in two grades - "V" and "PV". The first are created on the basis of flax or hemp oils. To create the second, petroleum polymer resins and other technical oils are used. Therefore, when working with drying oil, especially the PV brand, you should be extremely careful, wear respirators and protective gloves.

Often Oksol is marked "combined", "composite" or "semi-natural", which once again proves its origin. But sometimes it makes a fundamental difference for those who care about composition. Combined Oksol received rapeseed oil as a natural component, while sunflower oil was mainly used for production. But the situation was complicated by the fact that the new component belongs to the class of non-drying ones. Then it was pre-oxidized, and as a result, the combined Oxol received the same characteristics as the original version of the composition.

In the broad sense of the word, combined drying oil is obtained by mixing oils of several plants or those that have undergone different processing, the addition of synthetic substances and a solvent is also allowed.. The use of this option is more common in the preparation of paints. Drying oil of several brands is produced. In the designation, the first is the letter "K", followed by a number. If an even number is indicated in the marking, then the mixture is used for interior work, and an odd number is used for painting outdoor objects.

The last type is synthetic compounds. The basis for paints is alkyd drying oil, its cost is much lower than oil, which is a definite plus. Another type is compositional compositions. Their quality is not high enough, and due to increased toxicity, use is limited only to outdoor work. When choosing synthetic drying oils, one should be extremely careful, since if at least a small deposit of natural oils is present in them, then the layer after painting may not dry out for a very long time. The presence of such inclusions can be determined visually. This mixture has a reddish tint and a black precipitate.

Specifications - we study GOST

Drying oil Oksol (GOST 190–78) is characterized by the following properties. Due to the solvent, it has a pungent odor that does not disappear immediately. The time of complete drying is no more than a day. In addition, drying oil Oksol is highly flammable and toxic, therefore, when working with it, all safety rules should be followed.

According to GOST 190–78, marking is carried out depending on the composition, for example, drying oil “B”, which has excellent properties, is made only from hemp and linseed oil. It can be used both for dilution and for the manufacture of oil paints. It is also acceptable to carry out external and internal painting work. Drying oil "PV", created on the basis of other technical vegetable oils (sunflower, grape, soybean, corn, etc.), has a similar purpose, but its use is limited only to indoor work.

Both types of Oksoli cannot be used for painting floors.

The technical characteristics of drying oil Oksol are indicated in GOST 190–78, but nevertheless we will dwell on them in more detail. The acid number for type "B" is no more than 6 mg KOH/g, and for "PV" - 8 mg KOH/g. The exception is drying oil based on sunflower oil, in which case this figure can reach 10. It is unacceptable for the sediment to exceed 1%, transparency must be complete. The mass fraction of non-volatile substances ranges from 54.5 to 55.5%, regardless of the brand. The flash point in a closed crucible is above 32 °C.

Drying oil Oksol is stored mainly in metal containers, but it is strictly forbidden to open it with tools that give a spark. When transporting, it is necessary to use the transport marking, namely the “Keep away from heat” sign. In more detail, all the characteristics of the composition, as well as safety requirements, test methods and acceptance rules are described in GOST 190–78.

The wisdom of coloring products with Oksol

Now consider the features of the use of drying oil Oksol. In general, there is no great difficulty in this, but we want to highlight some of the nuances, so we will analyze the order of work.

How to paint products with drying oil Oksol - a step by step diagram

Step 1: Preparatory Stage

Due to the pungent odor and toxic emissions, special attention should be paid to safety. All work is carried out in overalls, respiratory organs also need special protection, so you should prepare a respirator in advance, and rubber gloves are put on your hands. If the composition has got on the skin, then it is necessary to immediately wipe it off with a rag moistened with vegetable oil, and wash the damaged area well with warm water and soap. Avoid getting drying oil in the organs of vision. In addition, open flames are prohibited in the premises where work is carried out. And all lighting sources and electrical equipment must be reliably protected from explosions. And make sure you have good ventilation.
