Why is wood impregnated with linseed oil? Linseed oil for wood. How to Protect Wood Surfaces Preparing Wood Finishing Oil

The tree has a combination of good consumer properties, with the exception of the ability to absorb moisture and rot, so it needs to be processed.

One good preservative is linseed wood oil, which can form a protective layer on the surface to prevent water particles and biological organisms from penetrating. Processing is inexpensive, takes a short period of time, gives a good result.

Properties

Oil extracted from flax seeds is used as a culinary product and a multifunctional technical tool. A large number of useful qualities due to its structure, chemical composition.

The basis of the unrefined plant extract is triglycerides, which include from 60% to 90% polyunsaturated (linoleic and linolenic) acids. The biological significance of such acids is multifaceted, so flax seed oil is widely used as a food supplement.

For production purposes, in particular for coating wood with linseed oil, technical grades with a less thorough degree of purification are used. When dried, the acid residues polymerize, forming a strong film, similar to drying oil coating.

Processing Features

The formation of a natural oil polymer can take a long time, so the treated wood must in any case dry for a long time. Raw oil is well absorbed by the wood base, penetrating deep into the inner layers.

The drying of the portion absorbed into the microcells lasts even longer, so you should not rush to apply the next layer. After waiting a few days (usually 3 days is enough), you can re-impregnate the tree. In general, the procedure should be repeated 5 to 7 times.

The process can be accelerated by special catalysts - driers, which initiate and accelerate the crosslinking of molecules. Small amounts of metal oxides are used as activating additives. The product obtained in this way, in fact, is drying oil; under normal conditions, it covers the wood base well and dries in a maximum of a day, which is much faster than when treated with raw linseed oil.

Furniture, woodwork, crafts and household kitchen utensils receive a reliable protective barrier against external influences.

Impregnation of wood with technical linseed oil achieves several goals:

• neutralize the effect of moisture;
• exclude the ingress of microorganisms;
• improve appearance;
• mask small surface defects;
• enhance the decorative effect of the natural texture;
• maintain air permeability;
• extend the life of the product.

An additional positive quality of linseed oil is its complete harmlessness to humans both during processing and during subsequent use in everyday life.

Linseed oil has no chemical odor, does not emit fumes into the environment; the technology is easily implemented in production and home conditions. You can process wooden surfaces without special special devices with your own hands in ordinary rooms.

Wood preparation

The main condition for proper processing is the coating of dry wood, the moisture content of which should not exceed 14%. If the wood is old, dust, residues of dirt, paints and varnishes must be cleaned from it. Moreover, it is not recommended to wash it with a damp cloth. Otherwise, you will have to dry again additionally or wait for natural drying. The cleaned surface of the tree should be treated with sandpaper.

If work is carried out indoors, you need to check the humidity, the maximum values ​​\u200b\u200bof which should not exceed 70%. You can carry out processing on the street in warm, sunny weather.

Note! Linseed oil is important to apply correctly: a thin layer, repeating the procedure several times. If you rush and distribute a large portion on the wood at once, you can ruin the whole thing.

Small items made of wood can be immersed in a container, poured with oil and soaked. In large products, the agent must be carefully and methodically rubbed along the fibers.

It is convenient to distribute the product with pieces of foam rubber or brushes, which, at the end of work, must be placed in cold water. Keep the linen product in a cool place, preferably at low temperatures. Otherwise, slow polymerization and oxidation may take place, which will ultimately lead to deterioration of the drug.

On items that are not subjected to heavy mechanical stress, the action of the protective layer is enough for 2-3 years, which makes it possible to do it slowly and calmly.

With the processing of floors will have to tinker; with high abrasive loads, it may be necessary to carry out the procedure up to 4 times annually. The result will justify the physical and time costs. The surface of the floor will look great, serve for a long time.

Preparing the wax mixture

To increase the protective effect, you can make a tool with enhanced protective properties with your own hands. Adding small amounts of wax will make the surface of the wood silky and even smoother. This composition can process light and dark products located in areas of high mechanical stress: on floors, stairs, armrests, doors.

The recipe is simple and easy to follow under normal conditions.

A portion of linseed oil should be slightly heated in a water bath, then gradually add pieces of beeswax to it. The ratio of components must be equal. If desired, you can increase the amount of wax and get a thick mass, or, conversely, reduce the total mass of the pieces and make a viscous liquid.

When working, it is important to remember that all substances used are organic in nature and can easily ignite near fire. Therefore, after the complete completion of the work, the brush should be thoroughly washed with a solvent, completely dried in a safe place, remote from sources of flame. Pieces of foam rubber, patches soaked in linseed oil should not be scattered, but neatly collected in one bag, the contents of which can then be burned.

During self-preparation of the mixture in the bath, overheating, direct contact of linseed oil with fire should not be allowed.

Purchased in stores or well-made with your own hands, tools will help keep the tree unchanged for many years.

Linseed oil is traditionally used to treat houses and wood products. Undoubtedly, linseed oil for wood is the most valuable product that best ensures the safety and protection of wood material. The classic version involves the use of the product in its pure form. However, despite the obvious advantages, the traditional product has certain disadvantages that cause inconvenience in its use and limit the scope of use.

The modern industry offers a lot of professional impregnations based on linseed oil, in which all the advantages of the product are most clearly manifested and at the same time its disadvantages are completely eliminated. In the review, we will consider both those and other means, and find out what effect their use gives to wood.

Linseed oil is a natural product. It is made from flax seeds, which undergo various processing methods at the production stage:

1. Pressing (cold or hot).
2. Extraction.

Cold-pressed oil contains fewer impurities, has a mild odor and has a longer shelf life.

During hot pressing, an oil with a specific smell and taste is obtained, which has an intense color.

Extraction involves the extraction of oil with the help of solvents. The resulting product undergoes refining, as a result of which a pure, slightly colored fat is formed with practically no smell.

Oil types

Depending on the method of production and processing, the output is a product endowed with certain properties and characteristics:

1. Unrefined oil. It has no mechanical impurities, retains all its properties (smell, color and taste). With prolonged storage, the product deteriorates and forms a precipitate.
2. hydrated oil. It is an unrefined oil treated with water. As a result, the properties of the original product are preserved, but without the formation of sediment.
3. Refined oil. Processed with alkali, the result is a clean oil without sediment, with low color and odor and a long shelf life.

Which oil is better: food or technical

All of the above types are edible oils that can be used for wood processing. However, not everyone knows how much food formulations dry. Note that these products have a long drying period. After treatment, at least 7 days must pass before the surface dries out, and it will be possible to apply the next layer of oil impregnation.

It should be noted here that, since the oil is highly absorbent, 3-5 or more layers will be required to obtain a high-quality coating. Thus, the processing process can stretch for one and a half to two months.

Unlike food, the process of polymerization of technical linseed oil proceeds much faster. A strong protective film is formed on the surface, protecting the tree from moisture and insects. Due to this property, technical oil is most often used in the construction industry to stabilize wood.

fire hazard

Any vegetable oil, including linseed oil, is an organic substance that ignites in the open air when it reaches a certain temperature. Oil also ignites when in close proximity to an open flame.

However, when applied to wood, the oil does not increase its flammability. Over time, oxidative processes occur in the oil. As a result of oxidation, the oil ceases to support combustion.

Advantages

Linseed oil has characteristics that are most valuable when applied to wood - good waterproofing, antiseptic and protective properties.

1. A tree treated with linen composition receives reliable protection from moisture, the appearance of blue, damage by microorganisms, including various types of fungi. With the help of linseed oil, drying and cracking of wood can be prevented.
2. The oil has the ability to be completely absorbed into the wood, penetrating into the deepest layers. Only the smallest part of the applied agent remains on the surface. Thus, not only the outer surface is protected, but also the inner wood layers. Linseed oil does not form a film, and does not deprive the tree of the ability to "breathe".
3. The use of linseed oil improves the aesthetic characteristics of wood. The surface becomes matte, the oil coating emphasizes the natural beauty of the wood pattern.
4. Linseed oil is great for renovating old woodwork. It masks small cracks, abrasions and other minor defects, gives the surface dirt-proof properties.

Inexpensive price and availability (oil can be bought at any pharmacy or hardware store) add popularity to linseed oil, which today is one of the most popular woodworking products.

disadvantages

One significant disadvantage of using edible linseed oil has already been noted above - a long drying period. In part, this disadvantage is compensated by the use of a technical composition, which makes it possible to accelerate the polymerization process.

However, the use of a pure product has other disadvantages:

1. Oil polymerization in the inner layers of wood has lower rates than outside. As a result, a dry-looking product can leave greasy oil stains for a long time when touched.
2. Under the influence of ultraviolet, the drying period is reduced, but another minus pops up here: the color of the coating changes in the sun, which acquires a yellowish tint.
3. Wood treated with pure linseed oil needs regular renewal. The frequency of processing is once every 6-8 months.

Performance Improvement

Using linseed oil in its pure form, the question of improving the characteristics of the product always arises. To do this, there are a variety of both folk and professional means. Let's dwell on those and others in more detail.

Acceleration of polymerization

If edible linseed oil is used to process a log or log house, the following products are included in the product to reduce the drying time:

• turpentine;
• tar;
• wax.

When choosing a means to accelerate the reaction, it must be taken into account that turpentine is quite toxic, which limits its use only on external surfaces. In addition, it can cause skin burns and allergies, so you need to use protective equipment when working with it.

Tar is the same turpentine, it is obtained as a result of the distillation of wood. It is less toxic, but it is also undesirable to use it indoors.

Wax is absolutely harmless, it can be used both outside and inside the house. It is one of the best bath products because it does not form a film coating, it can also be used on the shelves of the steam room. Wax is used both in pure form and in tandem with linseed oil. To prepare the composition, the wax must first be heated in a water bath.

Composition cleansing

It has been observed that under the influence of UV rays, linseed oil turns yellow. To prevent yellowing of the log house in the sun, the composition is cleaned of impurities before application. To do this, use the following methods:

• preparation of brine;
• addition of lead salts;
• mixing with ethanol;
• exposure to light (photooxidation).

Color change

To give a particular shade, linseed oil is tinted with natural pigments. Beautiful colored coatings are obtained if the wood is first covered with a stain, and then a clear oil is applied. In this way, you can achieve a wide variety of shades: from natural to bright exotic.

Some craftsmen, to tint the oil, use improvised means, for example, spices: corn to color yellow, paprika to give a red tint, carrots to paint orange. In some cases, oil paints or gouache are added to the oil.

professional tools

All of the above methods are used exclusively by home craftsmen in order to save money. All of them are available, but at the same time significantly complicate and lengthen the painting process. When using pure linseed oil, improved by improvised means, it is impossible to achieve high quality painting and durability of the coating.

Today, there are many professional linseed oil based products under the brands Osmo, Tikkurila, Remmers, Biofa, GNature, Teknos and others. The products of these companies are widely used and have earned a lot of positive feedback from consumers.

Impregnations include additional components that improve the quality characteristics of linseed oil:

• desiccants, to speed up the polymerization process;
• additives that increase resistance to UV radiation and increase the protective and water-repellent properties of the oil;
• antiseptic additives;
• color pigments.

Manufacturers produce different types of impregnations intended for internal and external processing. You can choose glazing (transparent) or tinted coatings that give the tree the selected shade. A wide palette of colors allows you to choose a tool for any interior.

In the product line of each manufacturer, you can find specialized oil impregnations:

• to cover various elements of the house: floor, ceiling, walls;
• for baths and saunas;
• for processing furniture and countertops;
• for terraces and decks.

Each product has a specially designed composition that allows you to effectively solve the tasks, and its application technology. Impregnations based on linseed oil have good absorbency and low consumption. The service life of the coating obtained with the help of professional impregnations increases to 8-10 years.

Oil application technology

Stages of work

Work on processing a house from a bar or a log house from logs will be similar. They can be conditionally divided into three main stages:

1. Surface preparation. This stage includes surface cleaning and polishing. If you are painting a new house with a painted surface, first of all, the old paintwork is removed.
2. Priming and antiseptic. This step is mandatory if pure oil is used. If processing is carried out by professional means, the manufacturer's recommendations should be followed. Some impregnations already contain an antiseptic and soil in their composition, which must be indicated in the instructions.
3. Direct application of impregnation.

The process of applying oil to a tree is described in detail in the article. Therefore, in this review, we will not dwell on the description of all stages, but will only give the basic rules of oil painting.

Oil painting rules

Before starting work, it is necessary to determine the moisture content of the wood. The optimal indicator in this case is 15%.

Air humidity during painting is also essential. It should be within 80%.

Conifers with high resin content must first be impregnated with white spirit.

When painting wood with pure linseed oil, at least 4 coats are required to obtain a better result. When using professional tools, you must follow the manufacturer's instructions. As a rule, to achieve the desired effect, impregnation manufacturers recommend applying 2 layers to unpainted wood, and one to painted wood.

You need to apply the oil in the direction along the wood fibers with a stiff brush with artificial bristles or a lint-free cloth.

Be sure to perform interlayer grinding after each layer of oil has dried.

After the last layer has completely dried, the wood is polished with suede. Polishing allows you to give the surface an even beautiful shine.

To check the quality of the resulting coating, you can apply a few drops of water. If the liquid remains in place, then the processing is done well.

DIY painting mistakes

Often, non-professional craftsmen, having received superficial information from the Internet about the technology of applying oil, do the work on their own. This inevitably leads to errors in the work, which affect the quality of the painting.

The following are typical mistakes that non-professionals often make:

1. Technology disruption. Despite the fact that in general the process of applying different types of oil is the same, each impregnation has its own unique composition, which introduces certain nuances into the rules for processing wood with this product.
2. Insufficient surface preparation. Many do not attach due importance to the preparatory work, they do not clean off the old coating well, do poor-quality grinding, leave bumps and cracks. As a result, after applying the oil, all defects protrude, which greatly worsen the appearance of the coating.
3. Carrying out work at high humidity of wood. Humidity is a very important indicator, if you apply oil to undried wood, the impregnation will not be able to penetrate into the deeper layers and provide full protection.

To avoid these and similar mistakes, contact professionals. The company "Master Srubov" has more than ten years of experience in finishing and processing wooden houses. In our company, special attention is paid to quality, all work is carried out under strict control by the technical supervision department.

Wooden structures made from natural material. This is a favorable environment for the life of organisms, especially when placed outdoors. Therefore, wood products require careful treatment against destruction caused by fungi (mold), bacteria (rot), insects (mechanical destruction). Yes, and in the room impregnation is not superfluous. For example, in the kitchen, the humidity is quite high, which destroys the wood. Oil is an effective method to combat external influences on wood.

Owners of private wooden houses know that the main property of oil impregnation is to increase the service life of the walls, giving them strength. Besides, any oil is a natural antiseptic to a greater or lesser extent. It kills bacteria on the surface, making it cleaner and more elastic.

There is a large selection of wood impregnation oils on the market.. They can be divided into two large groups - mineral and natural. Let's consider them in more detail.

mineral

They have gained great popularity not so long ago in connection with the active scientific and technological development. Then it became possible to create mineral oil with the required characteristics. About 50 years ago transformer oil began to be used for the purpose of wood processing. Of course, this is not its direct purpose. The result proved the opposite, which brought the sales of transformer oil to a new level. With the help of it, it is possible to prevent the putrefactive processes of the tree, while maintaining the primary appearance. Undoubtedly, the production of this product violates environmental standards. Therefore, more and more enterprises prefer natural oils or at least combine them with mineral ones.

natural

Natural oils appeared much earlier than mineral ones. It took time to realize their merits in wood processing. The spread of natural oils was held back by the high cost of raw materials. However, modern production methods solve this issue.

Their key advantage is vegetable origin. Natural components, the absence of harmful compounds make natural oil safe for humans. The most common types of natural oils for impregnation of wood products:

1. Wood oil. One of the very first products to protect wood from rot, water and termites. Suitable for impregnation of floor and ceiling finishes, wooden furniture, architraves and dishes.
2. Teak oil. A universal agent suitable for impregnating both internal surfaces made of wood (floor, ceiling, decor, stairs, railings) and external surfaces (facades, gazebos, furniture and garden figurines). The best choice for oak, beech and other valuable wood species. Ingredients: tung and linseed oils, refined turpentine.
3. Tar oil. It has pronounced antiseptic properties. Ingredients: stump resin, turpentine, linseed oil. Turpentine helps to better impregnate the material. Linseed oil stops the composition inside. Widespread in the judiciary. They process the bottom of boats and moorings. Suitable for exterior treatment.
4. Deservedly considered the most inexpensive and effective means of protecting wooden surfaces. Linseed oil It has a high hydrophobic ability, so it fights dampness very well. Particles penetrate into every pore of the material, emphasizing the structure and "preserving" it. Suitable for processing indoor and outdoor structures.
5. Tonic oil (toning). This type of oil is produced on the basis of condensed vegetable lipids, which restore the natural grace of the tree and protect it from destruction. It will be possible to avoid such problems as fading, cracks, drying out. More suitable for outdoor use, as the composition deeply penetrates the wood, literally repelling dirt.

Advantages and disadvantages of different types of oils

We found out that oils are used for one purpose - to increase the period of use. They have, although not much, but different properties. For example, one species has better water resistance, another copes well with dust, etc. We list the pros and cons of each oil.

Impregnation procedure and conditions

The most common method is rubbing into the surface. It is suitable for linseed, mineral oil. You need to rub the oil into the wood with sandpaper (P400) and a cloth napkin. The procedure should be carried out 3-4 times. After each use, the oil should be absorbed, i.e. surface is dry. This will take 3-8 days. A rag is needed for the initial application, as well as in the final stage - grinding. In exchange for long processing, you will get excellent results.

The second way is smearing. It is used only when the tree will be further covered with paint. The oil is applied with a regular brush. It is important that it be drying oil, for example, linen. Then the surface is leveled with a beige pad or cotton cloth.

The last 2 methods are boiling and soaking. For technical reasons, they are suitable only for small items: pens, toys. For soaking in a pan, you need to place the product and leave it for a couple of days in a closed state. After that, polish with a cloth napkin to a shine.

You can boil, then the time is reduced to 1 day. Digestion is carried out over low heat at a certain temperature, depending on the oil (see table below).

The nuances of impregnation

Before starting work, you need to prepare the tree. The first thing to do is check the moisture content of the wood. Better to keep it as dry as possible. Ideally, no more than 15-20% of water.

After preparation, a color test is carried out. An oil solution is applied to a small area of ​​the surface, after which the resulting color is evaluated, which depends on:

• tree species;
• the degree of its polishing;
• layer density.

Some companies, specializing in the production of tinting oils, offer samplers, giving the opportunity to know in advance what shade the product will acquire.

Pine, birch, fir - wood that requires the application of a special alkaline solution before oil treatment. This is done so that in the future the structure of the tree does not darken.

The application itself (if you have chosen the smearing method) goes in the direction of the fibers. It is better to collect excess oil in different places. Next, the wood is polished and left for some time, depending on the chosen method of impregnation. By the way, much less oil composition will go to pre-sanded wood.

Impregnation of wood with oil is needed for street structures made of wood. When decorating the walls of the house, you can’t do without it either. It increases the declared operational life of wood. Don't make silly mistakes, such as opting for mineral oil to impregnate furniture because it's not environmentally friendly. The correct selection of oil depends on the placement of the product (outdoors, indoors) and the material (wood species).

To extend the life of the log house, the wood is treated with various compounds. The products used increase the performance of the material and structure, help to preserve the aesthetic, attractive appearance of wood.

The most common substance used in formulations and in its pure form, without additives, to impregnate wood is linseed oil.

Benefits of impregnating with linseed oil

Linseed oil molecules are several times smaller than wood micropores, which allows the substance to penetrate deep into the wood structure, filling even the densest layers. They are much smaller than the molecules of artificially obtained oils, about 50 times, and this is reflected in the effectiveness of processing with a natural composition. In terms of the elasticity of the impregnated layer and the strength of penetration into the wood material while maintaining breathability, the impregnation with linseed oil is much superior to the treatment with synthetic compounds. When glazed, it is inferior to them only in terms of drying.
Oil impregnation protects the wood better than lacquer, which is prone to cracking from dents and scratches. Moisture gets into them and reduces the protective properties of the composition. Wood with an oil layer has a soft sheen, its texture is more noticeable and more attractive.

Just not for oak. Substances contained in natural vegetable oil and in oak wood react upon contact, and dark spots appear on the oak surface that cannot be removed.

After oil treatment, there is no dense film on the surface of the wood, the agent filled the micropores of the wood and increased the resistance of the material to drying, cracking, discoloration due to aging.
The benefits of linseed oil treatment include:

• environmental friendliness. The applied composition is non-toxic and does not emit substances harmful to health after application;
• high protective effect. During oil treatment, even micropores are clogged, which increases the efficiency of protecting the material from destruction;
• maintaining an attractive appearance.

Under a transparent coating layer, the characteristic wood pattern is clearly visible. The applied layer protects against rotting, darkening, fading under the influence of ultraviolet radiation;
antiseptic protection. The oil layer prevents the appearance of mold, fungi;
- hydrophobicity. The wooden surface becomes resistant to moisture;
- breathability. Treated wood does not lose its ability to pass air;
convenient application. With a substance safe for health, you can fearlessly treat the most inaccessible places;
- affordable price. The substance wins price comparison with the impregnating compositions of leading manufacturers. The cost of using it can be reduced by replacing edible flaxseed oil with technical oil by purchasing in bulk. To determine the volume of the purchased substance, the ratio is based on the ratio - 1 liter per 10 m² of coverage area.

Feature of flaxseed oil

Refined linseed oil is used in order to achieve high polymerization and special strength of the coating film. In the substance that has been cleaned, as in manual cold pressing, there are no non-polymerizable acids, it dries quickly, does not turn yellow, and the treatment will not lead to a change in the shade of the log house over time.
The protective properties and quality of polymerization depend on the amount of acid glycerides in the composition. Therefore, for impregnation, you need to choose an oil with a maximum content of linolenic, linoleic acid.

Other types of impregnation: what to choose?

Other oils and complex oil formulations are also used to stabilize the condition of the wood and improve its user characteristics. Sometimes the choice of what to process is influenced by the availability of ingredients.
1) Other oils
Drying oil is used, which is already partially polymerized oil - walnut, linseed, due to heat treatment. Further polymerization proceeds already in air and faster than with the use of raw thermally untreated oil. Ordinary oil is absorbed slowly, it takes several weeks to fully polymerize, and it takes more than a month to apply several layers. The thermally treated drying oil is absorbed immediately, after a day it dries up with the appearance of a film, on the 2-5th day after impregnation, the treated surface becomes inert, and it can be covered with a new layer.
You need to buy drying oil in special hardware stores. It is dangerous to get heat-treated oil at home by languishing on fire. Some manufacturers switched to the production of drying oil by safe chemical drying.
In stores you can find drying oil oksol, which attracts at a low price. It is made from sunflower oil, but it does not dry out, bitters and darkens over time. In order not to spoil the log house, it is better to choose other, more expensive than sunflower oils:
- hemp, the effect of it is similar to that obtained when using flaxseed. To reduce the cost of impregnation (1 liter - 600 r), they are looking for a cheaper substance obtained from technical plant varieties;
- tung, its purchase will cost a little cheaper (1 liter - 550 r). In terms of user characteristics, it is comparable to linen;
- other natural oils with the ability to polymerize - obtained from poppy seeds, nuts, white locust, pine and spruce seeds.
2) Oil formulations
For the conservation of wood - the introduction into its pores of substances that create a protective layer, compositions based on oils with wax, tar, turpentine are used.
So, means are used, the main component of which is linseed oil (40-70%), and additives - wax, turpentine, rosin. Linseed oil (50%) is mixed with other oils - tung (15%), orange (10%), and wax, rosin. Beeswax and carnauba wax are used, which improve the user properties of cheap waxes.
Apply the composition, which is prepared by diluting high-quality drying oil in a ratio of 7: 3 with turpentine. It is applied warm, heated to 50-60°C.
The log house can be given the desired shade by adding pigments to the mixture.
3) Waxing
If tar, turpentine are toxic and can provoke allergic manifestations, then mixtures with wax are safe for health and suitable for external and internal processing of the log house. Remaining on the surface and penetrating into the wood structure, wax provides good moisture insulation.
4) Compounds with synthetic components
Varnishes, paints with artificially obtained ingredients in the composition harden when dried. Impregnation of wood with such means is inferior in all quality characteristics to processing with compositions with natural ingredients. Its only advantage is that it dries quickly. Those who succumbed to the temptation to quickly treat the log house with impregnation with non-natural components face the flip side of such a decision - constant restoration work.

Frequency of processing and maximum period of its validity

The owner of a wooden house is simply obliged to protect his dwelling, made of logs or wood, from harmful insects and external influences.

For these purposes, apply wood coating oil is a technique that has been around for centuries.

How to choose the right oil among a huge variety of options, we understand in this article.

Why oil treatment is needed?

Owners use such oils to extend the life of the home and increase the strength of the wall made of wood.

Oils for wooden surfaces serve natural antiseptic and, penetrating deeply into the surface of the product, give its surface elasticity.

Compared to other impregnation methods for strengthening and protecting walls, oil solutions are made from natural ingredients, which indicates high environmental safety.

That is why oils, along with wax solutions, are considered the most harmless surface treatment methods.

Wood oils have a number of positive characteristics:

1. The ability to hide surface defects such as scratches and small chips.
2. Relatively low price for impregnating material.
3. Environmental safety of the composition intended for application to the surface.
4. Ease of application, which even a novice master who has never tried to cover the walls and floor on his own can handle.
5. availability of such materials.
6. Aesthetic component: after processing, the walls and the floor acquire a matte shade and a velvety surface to the touch.

Like any material, oil coating has its drawbacks:

Types of oils for coating

Wood protection can be carried out with various types of impregnations, but the desired effect can be achieved with such oils:

• linen;
• mineral;
• tar;
• wax oil.

Tar

Tar oil recognized as one of the most effective antiseptics and is made from natural ingredients such as linseed oil, pine turpentine and stump tar.

When impregnating a wooden surface, pine turpentine penetrates deeply to the entire depth of the treated surface.

And linseed oil, which is also part of the product, does not allow the oil to flow out from the depths and securely holds it in part of the tree.

This type of impregnation is widely used in the processing of log buildings, summer houses, boats and furniture.

After such treatment, the owner will protect the surface of the walls from beetles that spoil the material and rot, which such types of surfaces are often exposed to. In addition to protection, the wall will receive extra natural shine and transparent texture.

It is impossible to dilute tar oil, as it will lose its beneficial properties. The material on the surface will dry for at least a week, and maybe longer, depending on the temperature conditions in the room and the quality of the product being coated.

If a preventive and regular coating is carried out in one layer, the surface will dry out earlier than in one day.

It is recommended to store this oil in a cool place with dry air. It should not be exposed to low temperatures, and with a tightly closed lid will last a long time even with a long break in work.

Linen

This type of oil is rightfully recognized as one of the best in working with a wooden surface due to its waterproofing properties.

The tool is relatively economical from a financial point of view, and it is easy to find it on store shelves.

Flax oil is used to correct and treat surfaces on the inside and outside of the house, as well as for facade work, impregnation of the floor and walls.

The tree after such processing becomes reliably preserved and protected from moisture on the surface. The oil is able to hide minor texture defects such as scratches, cracks and chips on the surface.

Mineral

Mineral oil has been around for decades. Working with such oils is possible only with deep cleaning of such a product, and if it is not harmful to human health.

Such oils, produced according to established recipes, are often used in factories, but applying such impregnations not recommended for daily home use.

The use of such impregnation agents is justified only for reliable protection of external elements. The situation is complicated by the fact that such compositions practically do not dry out and are not amenable to forced rinsing from the surface.

Sometimes for parts made of wood, as well as protecting non-residential premises from pests, a mixture of vegetable and mineral oils is used.

Toning

Tinting oil is used to coat wooden surfaces and give it a characteristic and rich color.

Modern manufacturers guarantee the safety of the applied material and its quality, designed to extend the life of the wood species used in houses.

The composition of this oil includes pigments of natural origin, which allows the surface on which the tinting base is applied to acquire a natural shade.

The material has fast drying property and reliably protects the surface of the walls from pests and decay.

Oil-wax

Impregnations using a composition made on the basis of oil and wax ingredients, unlike paint coatings, have a number of positive advantages:

1. The ability not to spoil, but preserve the natural grain of the wood.
2. High stability to temperature fluctuations.

The use of such compounds is permissible in rooms with high humidity. The impregnating material is deeply absorbed into the surface, and contributes to the reliable protection of the product.

3. The vapor permeability of the surface is provided by such a composition, and allows the treated surface to “breathe”.

If a defect is found in any part of the wooden surface, it can be impregnated with a composition of oil and wax, and at the same time not to do the same procedure with all wall surfaces. It is enough to apply a layer only on the damaged area.

In order to choose a high-quality composition for work, you need to pay attention to the components, in which it is necessary natural oils must be present such as flaxseed, tall or teak.

In addition to the oils, the composition must contain a safe, odorless solvent in which benzene is not used. In addition to the solvent and natural oil, the manufacturer fills the mixture with wax and pigments.

White and colored oils

This impregnation protects the wood surface, including damaged by a beetle or rot. It consists of natural ingredients and permitted production additives.

White oil is used by people who care about their health and want to tint the surface of the tree as they wish. The result of applying such oil to the surface of the wall is a light surface with slight shading.

After applying white oil, the room visually increases in space, and the overall atmosphere in the room becomes harmonious due to a pleasant visual effect.

white oil does not emit harmful impurities after the application process on the wall surface. The material has an increased shelf life in packages with an intact lid, sometimes its duration reaches six years.

Colored oil is used to preserve the natural properties inherent in wood, and to give the desired shade. It is used for various surfaces: pure wood, planed and sawn boards.

It reliably protects the coated wood from harmful ultraviolet rays and serves as a waterproofing agent.

Danish

Danish oil is often used to treat wood surfaces that susceptible to moisture. It can be a floor, walls or musical instruments made of wood.

The composition of this substance contains white spirit, a little varnish and linseed oil, which has undergone a cooking procedure.

Application to the product provides it quality protection from moisture and pests, deep penetration of Danish oil gives a satin sheen to the surface and gives a natural shine.

The advantages of this oil, of course, is high drying speed and complete enveloping of the treated surface of the product.

Paraffin treatment

Wood treatment with paraffin oil prolongs product life and eliminates excess moisture on the surface.

The vapor barrier properties have a beneficial effect in those places of the room where evaporation often occurs, for example, in the kitchen or in the bath (steam room).

Antiseptic formulations

Compositions that can protect a tree from bark beetles are produced on the basis of organic substances of an aqueous and oily composition. Substances made on a harmless basis are very popular among the owners of log houses.

Impregnations differ in that toxic substances do not emanate from them. This type of coating is dirt-repellent properties and is resistant to sunlight.

Sunflower

Sometimes sunflower seed oil is used for surface treatment, but this type of impregnating material Not recommended, because its composition contains practically no polyunsaturated fatty acids necessary to envelop and protect the tree.

Another negative of sunflower oil is its inability to polymerize, i.e. it does not dry completely. Touching a base impregnated with such a coating can stain clothing and skin.

What oil to choose?

Each type of work is characterized by the choice of oil, which is most suitable for their implementation. We will deal with each type of work and oils for them in more detail.

For outdoor work

When carrying out outdoor work, the master must focus on the thickness and texture of the wood and the effect that he is trying to achieve.

If there is a desire to give the surface an additional tint, then it is recommended to use matte linseed oil.

Such impregnations are produced in various shades, from natural to saturated colors. In addition, linseed oil has high protection against bacteria.

This criterion is important when choosing a coating, because the tree on the outside of the building is most susceptible to external influences of insects and various types of fungi.

For additional protection of wood during outdoor work, it is recommended to use an antiseptic impregnation "Vinha" from the brand Tikkurila (Tikkurila Vinha). It will provide long-term protection against wet drops and mold growth.

For interior work

Carrying out work with walls indoors is best done with impregnations Osmo or Varathane. They are made on the basis of natural oils and wax.

They are resistant to indoor humidity and temperature changes, which makes them indispensable for covering floors and walls. Impregnation prevents rot bluish tint and mold in the corners of the walls.
