Oils for treating wood indoors. Choosing the right oil to coat wood outdoors and indoors. How to protect wooden surfaces

Compositions on oil based- This universal solution, suitable for decorative finishing any wood. They do not create lasting and wear-resistant coating, but have a wide range of other advantages: excellent adhesion, ease of application, antiseptic protection, environmental friendliness. Treating wood with oil does not create a film on the surface of the product; it allows you to emphasize the natural beauty of the texture of the material and tactilely feel its texture.

Simple application technology allows you to avoid streaks, smudges, brush marks and other defects. If necessary, the finish can be easily removed and updated. Typically, oil is used for wooden items not subject to intense abrasion and moisture.

What oils are most in demand?

Linseed oil – characterized by ease of application, deep penetration into the wood structure, high resistance to influences external environment. The main disadvantage is the long drying process (up to 3 days). Large-pore wood is treated with linseed oil in several layers.

Drying oil - This is boiled linseed oil. Due to the presence of driers in its composition - catalysts that accelerate drying, the polymerization process takes no more than a day, which makes this type finishing is much more practical.

Tung oil , obtained from the seeds of the Chinese tung tree, effectively emphasizes the wood texture and forms a wear-resistant matte finish. The drying process takes about 24 hours. If linseed oil is more suitable for restoring old surfaces, then the use of tung oil is more appropriate when finishing new products.

Danish oil – finishing composition based on natural vegetable oils with the addition of resins and absorbent substances. Treating wood with Danish oil allows you to highlight its natural texture and create a durable matte finish. Drying time: 4-12 hours depending on the composition.

teak oil – a mixture of natural oils, resins and absorbent components. Finishing wood with teak oil allows you to get a durable decorative coating with a glossy effect. The drying process takes 4-6 hours depending on the specific composition.

What is dry oil residue?

Percentage of dry oil residue – important characteristic, which determines the features of the finishing composition. The dry residue refers to the percentage of non-volatile substances in the oil - these are various strengthening additives, waxes, inclusions that improve absorption, etc. The higher the percentage of dry residue of the product, the better covering ability it has. Accordingly, oil with a high solids content requires fewer layers of application. At the same time, the drying process (polymerization) of such compositions takes longer.

How to properly prepare the surface?

Before applying the finishing composition, the surface of the wood is sanded using abrasives of various grain sizes:

• wood with an open structure (oak, etc.) - coarse abrasives P150-P180;
• wood with a closed structure (maple, beech, etc.) - fine-grained abrasives P180-P240.

The sanded surface is removed from dust with a damp, lint-free cloth. When applying finishing to oily wood species (iroko, teak, etc.), it is recommended to additionally wipe the surface with white spirit.

How to treat wood with oil: general principles

The oil is applied to the prepared and dried surface using a swab or brush, followed by rubbing. Having evenly distributed a generous amount of oil on a wooden surface, let it soak in (about 15 minutes), then wipe off the excess composition along the fibers using a swab. Otherwise, the surface will be shiny, sticky, with possible staining.

Distribute the oil evenly to avoid spotting. Process the edges and ends first, because... due to the capillary effect, they absorb the finishing composition more intensively. In multi-layer processing, each new layer is applied after completely dry the previous one, with preliminary grinding with fine-grained abrasive.

The optimal temperature for treating wood with oil is 15-25°C. At readings below 10°C and high humidity It’s better to give up work temporarily.

Professional subtleties of oil application

If stains form on the surface, increase the amount of oil applied.

To give the composition a more liquid consistency, necessary for uniform distribution over the surface, place the container with oil in hot water. Avoid contact with open flames.

The oil should not be applied under direct exposure to the sun, as... it will be absorbed too quickly, which in turn will complicate reprocessing.

Use a special dispenser to impregnate the surface - a simple and ergonomic device that helps uniform application And economical consumption composition.

How does oil adhere to stain?

Oil and stain are not the best, but quite valid combination. Any stain impairs the absorption of subsequent compositions, because partially fills the pores. In combination with oils, it is allowed to use only stains on water based. At the same time, practice shows that a more effective alternative to stain in this case is tinting pastes for tinting oils.

How long does it take for oil to dry?

• flaxseed oil – 2-3 days;
• linseed oil – 24 hours;
• tung oil –24 hours;
• polyurethane oil varnish – 12 hours;
• Danish oil –4-12 hours;
• teak oil – 4-6 tsp.

Since oils harden (polymerize) during the oxidation process, reacting with oxygen, drying products should be done in a room with constant air circulation.

What you need to know about the risks of spontaneous combustion?

When they react with oxygen, oils oxidize. This process accompanied by heating, which can cause spontaneous combustion of cleaning cloths and other items used during work. Therefore, never leave oil-soaked rags rolled up: dry them unfolded outside and only then dispose of them. All items and materials (sanding felt, dispenser, sponges, etc.) that have come into contact with the oil should be stored in a sealed metal container.

Without wood, no construction is conceivable, and even in the process of repair (restoration), manufacturing various crafts it is used everywhere. Despite all the attractiveness of lumber, they are characterized by a number of significant disadvantages, which are well known - susceptibility to rotting, twisting, shrinkage, and so on.

Without leveling out all such disadvantages about the long service life of products ( structural elements) there is no need to speak from a tree. For their pre-treatment Various drugs are used. One of the most effective and inexpensive means of protection is mineral oil for wood.

General information:

• The use of mineral compounds in “pure” form is now rarely practiced - the choice of various preparations for wood is huge. Transformer oil, waste oil and a number of other oil refining derivatives have been replaced by complex products. They are called minerals a little arbitrarily, since natural additives are necessarily introduced into them to impart (highlight) certain properties. The difference is essentially in the proportion of components.
• Mineral oils are especially effective when processing wood species characterized by high density. For example, larch, teak, oak.

These include used (machine) oil, transformer (“spindle”), industrial, hydraulic and a number of others. It is enough just to identify their common (and significant) disadvantage - harmful fumes. Such compositions cannot be used for interior work. But when processing wood that is intended for use outside buildings, this factor must be taken into account. If impregnation rafter legs, stringers, buried parts of pillars (piles), timber for the support frame and the like is possible, then, for example, for the lining with which it is supposed to cover the gazebo, summer kitchen or veranda, it is better to choose a store-bought product.

Mineral oil for wood - how to evaluate quality

There are no ideal compositions - this is an axiom. But in relation to it is necessary to pay attention to the following indicators its quality.

• Depth of penetration into the structure of the material. This is precisely what distinguishes oils from other “protective” preparations - varnishes, glazes, and some impregnating compositions.
• Safety. That is, the oil should not release after use. toxic substances. This is especially true for wood, which is used for “open” structures, even if they are located on the territory (gazebos, benches, etc.), as well as in bedrooms, children’s rooms and rooms with an unstable microclimate (that is, where there are sharp temperature changes - kitchens, saunas).
• Water-repellent properties. For exterior work, even if the wood is covered with cladding - a must. Impregnation of samples used for the installation of sheathings, rafters, various finishes low-quality oil will lead to unplanned (ahead of time) repairs. The same applies to damp rooms.
• The ratio of mineral and natural oils. The larger the share of the latter, the better.
• Vapor permeability. High-quality composition should not cover the wood with film. Otherwise, one of the main advantages of the material is lost - the ability to “breathe”. This is especially important for finishing panels made of wood (lining, block house, for example). Excessive savings on oil will lead to the fact that you will have to spend additional money on various climate control equipment. Another way (if protective agent will cover the wood with an impenetrable film), it will not be possible to achieve comfort in the house.
• Transparency. Quality products after use should not change appearance wood (structure, pattern, shade). If it contains a coloring pigment and is inexpensive, then most likely it is colored glaze. It happens that unscrupulous sellers It is precisely this that is offered under the guise of mineral oil, just to sell off the surplus.
• No smell. This is evidence that this composition contains a minimum of “chemistry”.

Wood is treated with oil different ways– rubbing, boiling, soaking, impregnation. Choosing mineral composition, you must read the manufacturer's recommendations for its use. Is it suitable for the specifics of further use? It’s clear that if you boil wooden handle To hunting knife- not a problem, then it definitely won’t be possible to process the lining using this method.

Examples of mineral oils and prices

The packaging of the formulations available on the market is different. For convenience, their cost is indicated in Russian rubles per 100 ml, in relation to the Moscow region.

• RuChef (Russia) – 100. It contains petroleum jelly, so it is recommended as a universal remedy. This mineral oil is often used in everyday life for sharpening tools (primarily the cutting edges of knives) and processing cutting boards.
• Belinka Bio (Russia) – 135. It is distinguished by its depth of penetration and gives shine to the wood.
• Hard Top Oil (Italy) – 265. Characterized by increased wear resistance. An excellent choice for processing wooden handles of knives and butts of hunting rifles.

• Adesiv Paviolio 25 – 263. A big plus is low abrasion. This oil is often used by professional craftsmen for impregnation. floor coverings from solid wood (piece parquet, boards of expensive species).
• Supi Saunasuoja – 62. One of best options to protect wood before using it in damp areas.

Conclusion

When choosing mineral oil for wood, you must follow the following rules.

• Assess the quality of the composition. Buying a cheap drug will subsequently result in additional costs.
• Correlate the properties of the oil indicated by the manufacturer with the specifics of its application.

This approach ensures that there will definitely be no mistakes when purchasing mineral oil for wood. And choosing a composition only based on price or a beautiful label is a waste of time and money.

Flaxseed oil and drying oil: understanding the concepts

Flaxseed oil is a natural substance obtained by cold or hot pressing of flaxseeds. Pure oil can be used on its own finishing coating, but in the untreated state it is ineffective due to its low ability to polymerize (dry).

When talking about impregnating wood with linseed oil, they usually mean using drying oil. This is a modified composition heat treatment and the addition of chemical additives that accelerate the polymerization process. Drying oil is also called “boiled” or “boiled” linseed oil.

Features of finishing with raw oil and drying oil

Processing wooden crafts pure linseed oil, you should be prepared not only for long drying, which can take up to 3 days (for each layer), but also know a number of important features. The raw product is actively absorbed into the structure of the wood, so coating the wood with linseed oil has to be done in 5-7 or more layers. When it dries on the outside, it does not polymerize well on the inside, which is why a seemingly dry product can leave oil stains for a long time. Exposure to ultraviolet light significantly speeds up the drying process. In the sun, treated wood can dry out in 6-8 hours, but the tone of the coating will change: it will become yellowish or even slightly brown.

Olif, thanks high speed polymerization, has completely different properties: it dries quickly, is not so actively absorbed, and does not change its color. This makes it more practical to use. Regardless of the conditions, the answer to the question of how long drying oil dries is clear - no more than a day (at 20°C). This distinguishes it favorably from raw flaxseed oil. Further speaking about this type finishing, we will mean linseed oil.

Where is the best place to apply this finish?

Impregnation of wood with linseed oil does not provide solid protective film resistant to scratches and abrasion. But this type of decorative finishing is valued for something else, first of all - environmental friendliness, antiseptic properties, the ability to emphasize the texture of wood and preserve it from cracking.

Flax drying oil is used for finishing products used indoors. It is optimal for covering furniture surfaces that are not subject to intense abrasion, wooden walls and ceilings. She's being treated wooden dishes, Kids toys. It is appropriate to apply linseed oil to the surface as a decorative and protective finish. valuable species wood to maximize the preservation of their natural qualities.

How to coat wood with linseed oil?

Preparation. The oil is applied to a dry and sanded surface. Wood moisture content should be at least 15%. It is recommended to carry out work at relative humidity air no more than 80%. When applying the composition to oily wood, the prepared surface is additionally wiped with white spirit.

Application. For work, use a brush, swab or lint-free cloth. The composition is evenly distributed on the surface and allowed to penetrate into the wood structure for 15-30 minutes. Excess oil that is no longer absorbed is wiped off with a rag or swab along the fibers. To avoid staining, ensure that the oil is evenly distributed on the surface.

Each new layer is applied after complete polymerization of the previous one with preliminary sanding. The number of layers required (in the case of drying oil from 1 to 4) depends on the specific use of the product and the type of wood (small-vascular species require fewer layers due to low absorbency).

The complete drying time for each layer is up to 24 hours.

How to restore oil coating?

Over time, the surface impregnated with linseed oil changes its color, begins to look dry, or wears off. This coating is short-lived, but this disadvantage is compensated by the ease of its restoration. When applying a second coat, the oil will hide all scratches and restore the appearance of the wood. If desired, linseed oil can be tinted with pigments, achieving the desired color shades. For products not subject to intensive use, the restoration procedure is carried out every two to three years.

What is oil wax and how to make it yourself?

Linseed oil with wax is an effective decorative and protective coating that gives wood high moisture-proof properties and increases its wear resistance. Impregnation adds a silky shine to surfaces and emphasizes the natural qualities of wood. Suitable for processing light and dark wood. Completely natural impregnation is optimal for finishing wooden floors, stairs, doors, furniture and other items subject to intense wear.

It is not difficult to prepare linseed oil and wood wax yourself. The easiest way: add grated oil to oil heated in a water bath. beeswax and bring to a homogeneous consistency. The classic proportion by weight is 1:1. The ratio of wax and linseed oil can be varied, creating compositions of varying degrees of viscosity: from thick mastics to liquid impregnations that penetrate deep into the wood structure.

How to avoid spontaneous combustion?

The process of oil oxidation upon contact with air is accompanied by an increase in temperature, which can lead to spontaneous combustion of oil-vapor rags, tampons, sponges, etc. Before disposal, all consumables that were used for wiping off linseed oil should be thoroughly dried in a straightened state outside the room, or better yet, soaked in water or immediately burned. To store the dispenser and other tools in contact with oil, use airtight containers.

Wood, as is known, belongs to organic materials. All that pests such as bacteria, fungi and mold need is the presence of organic matter, moisture and oxygen. So without protection, the wood's chances of survival tend to be zero. For protective coatings They use a wide range of impregnations that contain potent substances that are not always safe for nature and humans. In this article we will look at one of the safest types of protection - wood oil.

As we have already said, there are different impregnations for woodworking. You can find aqueous solutions of salts, solutions based on alcohols and other organic solvents, and compositions based on waxes and oils. It is the last two groups that are of mass interest, since they are the most natural and safe - both for the wooden surface itself and for humans, pets and the environment.

If we look at the oil - properties and applications - we can easily see that we have optimal remedy. Wood treated with this impregnation not only retains its natural advantages and acquires hydrophobic properties, but also additional charm, looks solid and expensive. The oil is suitable for covering the most different breeds trees, including rare and valuable varieties.

The main enemy of wood is moisture. It penetrates inside through numerous pores and capillaries, which abound in the structure of the material. By treating the surface with oil, these channels are filled and remain inaccessible to water, while at the same time maintaining the wood's ability to "breathe".

Wood coated with oil is reliably protected from bacteria and mold. Moreover, as a result of oxidation, the composition partially polymerizes, thereby closing the pores even more. As we know, water does not dissolve fats, so the oil is not washed out.

Important! Oil fills the pores and clogs the capillaries, so it prevents moisture from being absorbed deep into the material. Bacteria, fungi and mold cannot survive in the absence of water, and the tree remains unharmed.

Features and benefits of wood oil:

1. Is effective means, repelling moisture and dirt.
2. Completely natural, environmentally friendly and safe.
3. Protects the material from biological corrosion as a result of the activity of bacteria, fungi, mold and insects.
4. Gives the surface a noble appearance, preserves decorative qualities, emphasizes the fiber pattern.
5. Protects the material from drying out and cracking, increases its elasticity.

Important! The product does not clog the pores so much that the board stops breathing. After applying impregnation, the material retains its ability to pass air.

It is interesting to know that there is also a tinting oil that combines the properties of protection and decoration. In addition, various impurities can be added to it, for example, wax, turpentine, rosin, biocides, fire retardants, etc. When purchasing a drug, be sure to inquire about its composition.

Ways to use wood oil

It is very important to consider how to apply oil-based impregnations. First of all, you should properly prepare the surface.

Preparatory processing includes the following steps:

1. Removing old finishes. If the surface is covered with paint or varnish, it must be completely removed or sanded.
2. Removing grease stains. If there are greasy or oil stains on the surface, they should be removed using turpentine or white spirit.
3. Treatment sandpaper. All surfaces of the product should be treated step by step with fine sandpaper (P100 - P150) to open the pores.
4. The better the wood is prepared, the smoother the oil will be absorbed.
5. Dust removal. Chips and dust must be carefully removed.
6. Impregnant treatment. For basic protection, you should soak the material with an antiseptic; IMPREGNANT GOODHIM 320 works well.

Important! Wood moisture content should not exceed 12 - 15%. The room temperature also plays a role; it should not be lower than +5 degrees.

Application method

To apply the oil, use a brush with natural bristles.

The impregnation must be thoroughly mixed. A small amount is then poured onto the board or a brush is dipped into the jar, thus applying the product. Next, it must be thoroughly rubbed along the fibers. The dosage depends on the porosity and type of wood, as well as its humidity and the qualifications of the painter.

When the entire surface of the board is evenly coated and painted, it should be left for 8 - 15 minutes. After this, you should take a clean cotton rag and remove any residue from the surface by rubbing it along the fibers. As a result, the structure of the wood is clearly visible. The finishing layer is applied after 6-8 hours.

Important! Oil-wax is thicker and requires more thorough rubbing, in addition, it is less absorbed compared to the first layer. Rub it in longer and harder.

Interior oil

Initially, wood oil was perceived as an interior oil. This is due to its environmental purity and naturalness. In addition, the use of oil impregnations is associated with the production of furniture and decorative elements. Indeed, oil treatment makes even inexpensive wood refined and pleasant to the touch.

The use of this method of protection indoors is justified from all points of view. Interior oils do not emit unpleasant odors, do not contain toxins and are even suitable for treating children's toys and furniture.

An example of a good interior composition is the product TM GOODHIM. This is an indoor wood treatment product containing 100% natural oxidized linseed oil with the addition of beeswax, carnauba and candelilla waxes, pine resin, UV filter and pigments. The solvent is gum turpentine.

Important! One of the advantages of oil is the ability to restore the coating of a damaged area without repolishing the entire product. The product is applied to the area and simply rubbed until its boundaries are completely smoothed.

Exterior oil

Oil impregnations for wood have found application not only in the interior, but also on outdoors. They are used to process the following products:

• facades of wooden or clapboard houses;
• platbands, railings and other elements of external decor;
• garden furniture, benches, tables, benches;
• fences, doors, wickets, gates and other wooden structures;
• sheds, barns, chicken coops and other similar buildings.

The application of external oils does not differ significantly from generally accepted rules. Please note that the product must be treated with an antiseptic before soaking in oil. This will significantly increase the level of protection and extend its service life. Will do well.

TM GOODHIM It also produces terrace and façade oils. These products are great for external use and consist of 100% natural linseed oil with the addition of waxes, turpentine, pine resin and other natural ingredients. The composition contains driers to accelerate polymerization, but they do not contain lead compounds.

Oils can be clear or tinted. Tinting allows you to change the color of absolutely any breed ranging from dark chestnut to whitish. To achieve a more saturated shade, more layers should be applied, this same measure helps to achieve more high degree protection from moisture and glossy shine.

Oil rating

The best oils for wood are always natural formulations. Products based on linseed oil have become most popular and widespread, as it penetrates deep into the wood and has water-repellent properties. Tung, teak and Danish oils are also used.

If you use regular oil, the results will not be the same as using the oxidized form. This form is distinguished by the fact that the oil has been previously purged with air or ozone, which makes it thicker and ready for rapid polymerization.

For better penetrating ability, the oxidized oil is slightly diluted with natural gum turpentine. This solvent allows the product to penetrate deeper into pores and small capillaries, thereby significantly increasing the efficiency of impregnation.

To improve the strength properties of the polymer film, components such as natural wax are added to the composition. Beeswax and carnauba wax have proven themselves to be particularly effective. Additives of other oils, such as pine, are also used.

Considering that hardening will occur under conditions of weak UV radiation and the absence of wind, the product is improved by introducing so-called driers - salts of certain metals that accelerate polymerization. Good varieties do not contain lead salts or other harmful metals.

So, good oil for a tree must meet the following criteria:

• consist of natural raw materials;
• be pre-oxidized;
• contain other oils;
• contain natural wax;
• be slightly diluted with a natural solvent;
• include lead-free driers;
• have a dry residue content of at least 90%.

Important! Dry residue is one of the main indicators of the quality of wood oil. The higher this indicator, the higher the coverage of the product, and accordingly, fewer layers will be needed.

For those who do not know which wood oil to choose, we will present a table with the best, in our opinion, manufacturers. There will be Russian and foreign companies here.

Cost of wood impregnation

Prices for oil impregnations greatly depend on their purpose and the country of origin of the brand. In addition, the composition and quality of the components plays a significant role. average price in Russia is approximately 500 rubles per liter if we are talking about high-quality oil with all additives and processing stages. However, if you buy oil from the manufacturer, the price can be significantly lower. For example, like GOODHIM - start from 400 rubles per liter.

Working with wood and restoring wooden surfaces during repairs involves the use of oils for impregnation. The Belinka store offers customers products from the manufacturer - oil-based water-repellent impregnations for wood, which are used along with varnishes and quality paints.
