Everyone sooner or later faces the need for repair. Today in the construction market there are many tools and materials that will help you update the interior or exterior on your own. One way is to paint interior wooden surfaces - window frames, doors, floors or even walls.

A wooden surface painted with drying oil does not always look attractive.

Many are not serious about solving this issue, so they buy the first available (that is, cheap) paint and start working without preliminary surface preparation, which becomes the main mistake.

If we are talking about a clumsy process with a roller, the result of which is visible on each fence, then the direction is chosen correctly. But at the heart of any well-made finishing operations is attention to detail, which should be taken care of in advance. Otherwise, you can waste not only time, effort and money, but also completely spoil expendable materials and the wooden object itself.

Therefore, it is important to consider the nuances. For example, what to do if the wooden surface has already been covered with a coloring or strengthening solution: varnish, paint, impregnation or drying oil? The last composition causes difficulties more than others, therefore, first of all, you need to figure out: with what and how to paint drying oil previously applied to the surface of a wooden material?

To answer this question, one should get a little closer acquainted with such building archaism as drying oil, and understand why its use today causes such heated debate, both in the professional community and in amateur circles?

Features and disadvantages of drying oil

Drying oil is a film-forming liquid consisting of residues of vegetable oil (linseed, hemp, sunflower, mulberry, etc.), which is processed in a special way (by overheating or oxidation). And the solvents and desiccants in the composition make it related to oil paints, varnishes, primers and putties. In other words, drying oil as a finishing mixture can be used as any lubricant or coloring raw material.

Drying oil is both a coloring and impregnating agent

In the Soviet years, oil paint based on drying oil was almost the only available means of painting surfaces. It was applied literally to everything: floors, walls, ceilings, doors, windows and even furniture. When removing worn-out wallpaper layer by layer, old bathroom tiles or worn linoleum, you can most likely stumble upon a pro-oiled surface. Previously, not a single repair could do without it.

With the advent of new paint and varnish mixtures on the shelves of construction stores, drying oil was used only for puttying purposes, in order to give integrity to the porous structure of the material and protect it from moisture. Due to the viscous composition, drying oil has good filling capacity, which significantly reduces its consumption. Another area of ​​application is painting. metal surfaces and walls and ceilings in office premises (toilet, locker room, industrial kitchen), where there are hoods. In addition, concrete surfaces are primed with it and wood is renewed in outdoor work.

With all its advantages, drying oil has a number of significant drawbacks, which are well known to those who have at least once tried to apply another paint and varnish substance to it without pre-treatment. Among the obvious disadvantages should be noted:

• low adhesion (adhesion) in relation to other means of painting, so even the most expensive paint will “peel off” after a short time;
• a strong smell, which neither in the process nor after it never completely disappears and a stuffy, unpleasant atmosphere is created indoors;
• slow drying, from several hours to a couple of weeks, depending on the type and composition (the fastest is natural, and longer is synthetic);
• fire and explosion hazard, due to the presence of flammable solvents in the composition;
• inconvenience of use, since it is necessary to work with it only in a warm room (over 20 degrees), warming up the mixture in advance;
• fragility.

It is not recommended to paint with cheap drying oil, it has a number of negative qualities

It must be said that all of the above negative points are for the most part characteristic of low-quality, cheap drying oil. A good coating has them only in part.

It would seem that it is simply impossible to repaint the surface soaked with drying oil. But the situation is not as dire as it seems at first glance. The main thing is to choose the right tools and paint.

Choice of paint and tools

When working with oiled material, the choice of the correct paint is of paramount importance. Anyone who tried to put paint on drying oil invariably noticed: a freshly applied coating “bubbles” as it dries, and opened bubbles have a yellow, resinous content and a characteristic smell of drying oil.

However, there are several types of dyes and finishing materials, which I can cope with a difficult drying oil. These include:

• Oil paint;
• alkyd paint;
• acrylate oil paint;
• pentaphthalic enamel (or otherwise called PF-115);
• nitrocellulose varnish (or otherwise called NTs-132);
• oil-based liquid wallpaper;
• self-adhesive paper or film.

Pentaphthalic enamel easily copes with drying oil and lays down perfectly on top of it

Any of these options is perfect for painting not only wood, but also concrete and metal surfaces. You should not try to paint drying oil with quick-drying nitro enamel or water-based paint: our tricky oil-based impregnation will simply “repel” a layer of paint. For the use of water-dispersion and water-based paint the surface must be washed and cleaned well, removing the film from drying oil. In this case, 2-3 layers of water-based paint will cover the surface, but, unlike other compositions, will not saturate it.

A few more new devices are bought to the standard set of tools:

• roller or brush;
• airbrush, or spray gun;
• paint mixing tray;
• a bucket of soapy water;
• clean rags;
• hard-bristled brush or sandpaper;
• metal spatula;
• tape machine or manual cycle;
• disinfectant composition (antiseptic, flame retardant, acetone, xylene, solvent);
• putty on wood or plaster on concrete;
• primer;
• gloves and respirator.

For pasting with self-adhesive film you need:

• stationery knife;
• powder or talc;
• water with washing solution;
• dry rag;
• pin or needle.

Self-adhesive film looks good, easily glued on surfaces pre-treated with drying oil

Everything you need is at hand. Nothing stops you from getting started.

Surface preparation

The importance of pre-treatment of the oiled surface has already been mentioned more than once. Only a short-sighted amateur who does not feel sorry for his wasted efforts and funds for materials can omit the preparatory stages. A thrifty owner would prefer to do everything once, but thoroughly and well.

So, here is the sequence in which you need to carry out the processing work:

1. Clean surfaces from mechanical impurities: traces of old paint or putty, rust, lime, grease stains, soot and dust. Depending on the type of material (wood, concrete, metal), this should be done with a metal spatula or a brush with stiff bristles. Wash with soapy water. Let dry.
2. Sand or, if possible, scrape the top layer (the latter - only for wood), using coarse sandpaper, a hand scraper or, even better, a scraper belt machine. Wash with water. Let dry.
3. Repair all chips and cracks with plaster or putty. Sand with fine-grained sandpaper. Wipe with a damp cloth.
4. Prime. Let dry. Sand it. Wipe with a damp cloth. Wait for complete drying.
5. Apply a disinfectant composition no later than 6 hours after the previous stage. Let dry.

These carefully done stages will greatly facilitate the application of paint and prevent their deformation throughout the entire period of operation.

After surface treatment, the painting process can only bring a good mood

Now that the negative properties of drying oil have been minimized as much as possible, it's time to start the procedure for painting or pasting the surface.

Painting work is carried out in several stages at a temperature of -30 to +40 degrees and a relative humidity of no higher than 80%:

1. To begin with, hard-to-reach places, welds, end edges are painted with a stripe layer with a brush.
2. The coloring solution is applied in one layer by means of vertical movements, directed from left to right or from the wall farthest from the door with a roller, brush or spray gun (at a distance of 20-30 cm). It is also allowed to dip the object into the paint mass. Waiting for complete drying time.
3. Metal surfaces are painted over in 2-3 layers and dry up to 3 hours, cement-sand, asbestos-cement and concrete should be painted in 3 layers, and wood - 1-2.
4. Rinse dry surface hot water(without the addition of soda or detergent) in order to get rid of streaks. Re-wipe before use.
5. (let's say, oil) you can by placing 2-3 cans of salt water or grated garlic on a plate next to the stained area or in the room.

It is very important to wait for the complete drying of each previous coat of paint before applying the next one. The final drying time of the finished coating at a temperature of +20 degrees is at least a day.

Check whether the surface has dried or not, perhaps by the traditional method - by placing a finger on the place of painting. If necessary, you should wait for a longer period.

Transforming a polished surface is not an easy task. But with a skillful approach and competent selection necessary tools and finishing materials in just a few days, you can revive the interior and give it a new, more attractive look, which will please its diligent owner for a long time to come.

Drying oil for wood - natural protection wood

It is no secret that wooden surfaces treated with varnish or paint have a significant minus - they become cold and lifeless. If you intend to preserve the beauty of texture, warmth and energy, we recommend that you pay attention to such a wood processing material as drying oil.

1 Compounds for wood - drying oil is different

Drying oils are a whole range of film-forming impregnations, which are traditionally based on vegetable oils that have undergone special processing. To improve the quality of oils, they undergo oxidation procedures and heating at high temperatures. Solvents are added to the compositions of drying oils to improve their viscosity - thanks to this, the impregnation can also be used for the preparation of special primers and putties, as well as oil-resin varnishes.

Drying oils can act as an independent protective and decorative coating of wood, or as a primer layer before painting or puttying, as a component for the preparation of paint compositions.

The existing compositions can be divided into the following groups:

2 Wood processing with natural drying oil - application features

Most often, linen, hemp and sunflower drying oils are found on the market. Natural linen drying oil has a light transparent color. It is used for priming wooden, plastered and metal surfaces, as well as in the process of preparing putties for wood, putties and plasters. pastes and for breeding light colors. The use of natural compounds is allowed indoors. How long does natural drying oil dry on a tree? At a temperature of at least 20 ° C - about 24 hours.

Hemp drying oil has a pronounced dark color. The scope of the composition is the same as that of flaxseed. That's just this liquid is used to dilute dark thick paints. Compared to the previous representatives of the group, sunflower impregnation dries out more slowly - after a day, undried liquid will still be felt on the surface. Its feature is high elasticity, however, in terms of hardness, strength and water resistance, it loses to hemp and linseed oil.

Natural compounds are great for treating wooden surfaces of various tools. Hunters love to soak their rifle stocks with them - after that the product is very soft and warm in the hand, it is pleasant to touch it with the cheek. However, this group is not suitable for impregnating floor coverings, since the film created by natural compounds does not have high strength.

3 Semi-natural, combined, synthetic - areas of application of drying oils

Semi-natural drying oils are mostly light brown in color. The resulting film on a wooden surface is distinguished by its hardness and good gloss, as well as sufficiently high water resistance. Basically, semi-natural compositions are used in combination with other paints and varnishes or as a primer. Like natural drying oils, semi-natural ones do not have sufficient strength to process floor coverings.

Manufacturers add modifiers to combined compositions that improve their qualities necessary for the production and dilution of thick paints. Also, combined drying oils are used for priming wooden surfaces before plastering or painting.

Do not forget that the liquid dries for at least a day - it is not recommended to apply a layer of paint or plaster until completely dry.

Synthetic compounds are used not so much for impregnation, but as a basis for diluting dark oil paints for painting outside, as well as for priming metal, concrete and plastered surfaces. Synthetic drying oil is also used for the preparation of various putties and pastes.

4 What is olifing - we impregnate the tree

It should be noted that drying oil is in demand among lovers of natural materials that are absolutely safe for human health. However, in terms of other parameters (strength, penetration depth, durability), compositions based on natural oils have long been losing to impregnations based on alkyd resins with fungicides and other modifiers.

Natural impregnation is most often used in the care of wooden products, which periodically, one way or another, need to be cleaned and polished. For example, it can be carpentry tools. Also drying oils from natural oils show themselves well in internal works ah - the treated wooden surfaces look very good, continue to breathe and flavor the air. But for outdoor work it is better to use more modern, resistant to temperature extremes, moisture and pests substances.

How to impregnate a tree with drying oil - a step by step diagram

Step 1: Surface preparation

Wooden surfaces should be degreased, cleaned and thoroughly wiped from dust. The surface must be dry.

Step 2: Application and impregnation

For application, you can use both a brush with long bristles, and a roller, paint sprayer or a cloth made of natural fabric. The main thing is that as much liquid as possible gets on the surface to be treated. Let it soak in and then apply another layer. The procedure can be repeated until the surface is absorbent.

Impregnation of wood with drying oil in one fell swoop is possible using a plastic bag. Take an ordinary bag (the main thing is to make it whole) and pour a little liquid into it. Then place the product there, wrap the bag and seal the edges with tape. For full impregnation, several hours are needed.

Is it possible to apply drying oil on varnish, how to choose the appropriate materials for surface treatment? Used to create a protective coating different types varnishes and varnishes. Their application takes into account the properties and characteristics of materials, the possibility of their combination.

Varnishes and drying oil belong to the group of film-forming substances used in the form of solutions. The final appearance of the treated surface depends on their type and composition. Lacquering allows you to protect or emphasize the structure of the painted surface.

After drying, the coatings form a transparent, durable film; varnishes are often used to apply the base layer.

The range of varnish compositions is represented by a variety of types, methods of application and properties. Among them are distinguished:

• bituminous varnishes, which are made from bitumen of special grades, form a black film when dried, are resistant to reagents;
• oil formulations are solutions of vegetable oils with synthetic or natural resins; when dried, they give a transparent yellow film;
• alcohol have a high drying rate, are produced by dissolving natural resins in alcohol;
• alkyd solutions - materials based on synthetic resins, are water resistant;
• alkyd-carbamide varnishes are used with hardeners; when dried, they form a hard coating;
• cellulose nitrate materials are used to apply a protective coating to wood products;
• polyester;
• polyurethane coating materials;
• epoxy and oil-polymer varnishes.

Drying oil for wood is different in composition, which determines the peculiarities of its use for impregnation and primer. Natural drying oil is made from plant components of flax, hemp, sunflower with the use of special additives.

The use as a primer helps to emphasize the beauty of the texture, the wood shows its pattern. Solvents are added to its composition, which increase the viscosity, and to improve the quality of the oil, they are oxidized and heated at high temperatures. They contain only 5% of a special desiccant additive that accelerates drying. Oksol consists of an oil component, a solvent and a desiccant. Thanks to this connection, it dries faster, and its cost is low.

Composite synthetic material is produced from by-products of the oil refining industry. This type of product is not universal due to poor quality. It is not recommended for indoor use.

The highest quality compositions based on alkyd resins have. They are used for outdoor interior decoration.

Coating Compatibility

As a finishing mixture, drying oil can be used as a component for the manufacture of putty, for painting metal surfaces. Disadvantages of this mixture:

• low adhesion to other surface coating agents;
• strong persistent odor;
• special working conditions (presence of high temperature in the room);
• fragility;
• long drying time.

In the case of repair work, it should be borne in mind that if varnish is applied to a fresh layer of varnished surface, bubbles will form as it dries.

If you treat the tree with drying oil, you can create not only a protective layer, but also a primer under the main coating with a tinted or transparent varnish.

The tool is used as a primer and impregnation of the material before painting.

Drying oil is an alternative means in relation to others used for wood impregnation. It is worth remembering that not all types can be used for work in residential premises. Guaranteed impact protection external factors achieved when combined with other means.

Some types of paints and NC-132 brand nitrocellulose varnish do not conflict with drying oil. When you try to apply a coating of other materials to the drying oil, repulsion will occur.

• using tools to clean the surface of contamination;
• wash with soapy water;
• sanding with sandpaper;
• repair cracks and sand the surface;
• apply primer.

A layer of varnish can be applied to drying oil only after final drying. In order for the coating to be stable, it is necessary to use glyptal, pentafle, oil varnishes. Apply with a brush, spray or roller. The choice of materials depends on the type of work performed. To cover the surface with a protective layer, you need to choose the right composition for application.

A careful study of the compatibility of funds will help you choose the best painting option. In the case of using several types of materials, it is better to choose them from one manufacturer. This will avoid conflict when working with them.

For the floor, parquet varnish is well suited, which has the necessary fluidity on wood, and when dried, forms a transparent film. You can dilute it with white spirit for even distribution over the surface. Drying oil consists of components of vegetable and synthetic fats. Applying it to a varnished surface will not give results.

When building and decorating houses, wood is often used, because it is one of the most environmentally friendly materials. However, in order for the wooden elements of your home to last as long as possible, so that they are not destroyed by fungus and insects, they must be protected. This task is easily handled by a tool such as drying oil.

Application of impregnation

The use of drying oil allows you to increase the service life of wooden structural elements for decades. This is especially true for rafters, because they are constantly exposed to moisture. Drying oils are synthetic and natural, purely homogeneous, polydiene, synthetically modified, slate, coumarone-indene, etc. The use of this agent will not harm either people or animals. After all, it is based on vegetable oil (up to 97%). Impregnation of facade wooden elements with drying oil allows you to protect them from temperature extremes and air humidity and, of course, from atmospheric influences. When processing a wooden surface with this composition, a solid, but at the same time elastic, is formed on it, which protects the tree from external influences, including from damage by a fungus. Natural drying oil is made from sunflower, soybean oil. The best product is based on linseed oil.

Currently, there are many impregnations that have a chemical basis, with excellent, by the way, characteristics. But at the same time, drying oil has not lost its relevance. The use of natural impregnation, in addition to environmental friendliness, has another important advantage - this is the cheapness of such material. Basically, drying oil is intended for interior decoration, its use in outdoor work gives only a temporary effect, requiring further coating with oil or varnish. In the manufacture of putties, drying oil is also used. The use of such products protects wooden surfaces from decay. The use of drying oil as a pre-treatment also reduces the varnish when performing paintwork. Usually the product is applied in two or three layers, and after that the surface is painted. It is also recommended to heat the impregnation to a temperature of 80-90 degrees Celsius, and then apply it hot to the tree. Thus, a better and deeper penetration of the composition into the pores of the tree is achieved.

Drying oil: impregnation characteristics

Now drying oil of three types is common: natural, "Oksol" and composite. Natural impregnation consists of 97 percent natural oil, the remaining three percent is a desiccant (a substance that promotes rapid drying). Drying oil "Oksol" in its composition has only 55 percent oil (linseed or sunflower), forty percent white spirit and 5 percent desiccant. Such impregnation is cheaper than natural. Composite compositions are characterized by a pungent odor; they include petroleum polymer resins that serve as substitutes for natural resins, as well as other petrochemical products. This type of drying oil is the cheapest. Composite impregnations are not recommended for use in residential premises, even on balconies, because even after these compounds have dried, there is still a sharp characteristic smell.

Now many people want to protect themselves from unnecessary chemistry. This also applies to wood products. Drying oil in this regard is a unique material! The origin of the name "natural drying oil" speaks for itself. Up to 95% of the composition may contain natural components of flax seeds, hemp, rapeseed, which is a very high indicator in the production of paints and varnishes.

The remaining 5% are synthetic compounds, but their specific gravity is so small that negative impact practically does not occur on the human body. The lower the percentage of synthetic chemistry in drying oil, the longer the wooden thing will last you.

When choosing, pay attention to the composition and choose a product with the maximum percentage of natural ingredients, this is the key to enhancing the properties of drying oil in wood protection.

Main purpose

Given the characteristics of the material, it should be noted why drying oil is needed:

• basis for painting external structures;
• impregnation of internal structures (wall and ceiling cladding, flooring).

After processing, it is necessary to give time to the coating so that it saturates the inner layers of the wood fabric. Drying time may vary, but you need to wait until complete drying. Further wood flooring at the request of the user, it is left in this form, or any oil paint is used.

The interaction of drying oil and oil paint will only strengthen the protective layer of wood. And also, the more drying oil is used, the less paint consumption, isn't it a plus?

You should not sit on the fence floors if you have just painted it, in the hope that the impregnation is entirely natural products, and it will be absorbed in 5 seconds. Wood processing indoors is as important as outdoors. Temperature fluctuations, air humidity - all this is not in the best way affects the tree.

You can process with drying oil the lining and floors. However, do not forget that the composition must be absorbed until completely dry, therefore it is strictly forbidden to enter the treated premises.

Remember that the main difference between internal processing and external processing is the lack of fresh air. If the sun and wind act as a natural “dryer” for outdoor areas, then maximum fresh air supply will be required for indoor processing. This is necessary so that in the shortest possible time the surface in the room dries well, and the unpleasant odors that even natural products have are weathered.

In addition to wood, drying oil and oxol are great for painting and preparing metals (at the priming stage). And drying oil can be added to plaster - a sort of universal helper builder.

The choice of drying oil

How to choose drying oil correctly? You can not be guided only by the rule that the higher the level of naturalness, the better. There are the following types of drying oil:

• Natural - the higher the percentage of natural substances in the composition, the higher the cost of the material and its quality. If a product with a 45% vegetable oil composition can be used for exterior painting, then drying oil with an oil content of 70% or more can be used for interior work. In any case, the impregnated surface will be protected.

• Combined- as close as possible to the source material. In its composition, as a rule, a natural base and white spirit (solvent) are mixed, which occupies 1/3 of the drying oil structure. Such a complex is used for external use - the effect of the solvent on the body is practically not noticeable, and drying is faster.

• Drying oil "Oksol" - the middle class of the product. The impregnation is made from 55% natural oils and is used both indoors and outdoors. Oksol is an excellent assistant in polishing small parts.

• Composite - the cheapest option for impregnation. Almost 100% consists of synthetic substances, has a sharp pronounced smell. It is strictly forbidden to use drying oil for the floor and other wooden surfaces in residential premises, no matter how ventilated they may be.

Having oil in its composition, drying oil will be an excellent base for paint. And this is not about applying a layer of paint on a dried layer of drying oil. Oil-based paint - combines the properties of both substances and does not require varnish.

MA-25 - this is the name of the paint for the treatment of external surfaces, which is made from combined drying oil.

Application method

In order to properly treat a wooden surface, you do not need to complete painters' courses, but you still need to follow the basic principles of working with painting:

1. Before using drying oil or oxol, the wooden surface is cleaned of dust, grease and dried thoroughly. Application to wet material is extremely inefficient.
2. Too thick a solution, if desired, can be diluted with a solvent or nefras. Paints are used only after thorough mixing. No matter how fresh the jar is, stirring gives the drying oil structure oxygenation and reabsorption of the released oils.
3. To cover the tree with drying oil, either a roller or brushes are used. Small details are painted with small brushes.
4. Drying oil for wood and oxol with a maximum natural composition dry for about 24 hours. Since you need to use several layers for greater effect, it is important to understand that it will take several days to carefully work out the detail. Synthetic drying oil dries out in much less time.

When working with drying oil, it is important to protect the surface of the hands from material ingress. If you still get dirty, carefully remove the top layer from the skin, while moistening it vegetable oil. If the solution remains on the skin, you can remove the residue with a solvent, then wash your hands thoroughly with warm soapy water.

Conventional impregnation in its composition contains mainly chemical components. Drying oil also consists of natural ingredients. Why waste energy, money and time on synthetics when you can protect your own health and wooden surfaces with natural materials?

When choosing a product, pay attention to the manufacturer. Today on the market you can find by-products that are produced under the name "linseed oil", but their composition is not much like it. Therefore, trust the work only with high-quality materials and well-known manufacturers, and your wooden crafts will serve for many years.
