Varnish or oil for wood - which is better for processing
Oil or varnish for wood - what it's better? To begin with, it should be said that both are the final wood coating. Both varnish and oil are required in order to protect wood from mechanical stress and abrasion, water and moisture, thermal effects (hot dishes, boiling water, sun rays), ultraviolet rays and even pollution.
Both varnish and oil are required to protect wood surfaces. They are both colored and colorless, glossy or matte. The choice in favor of varnish or oil is always based on the purpose of the room, as well as its passability.
What is oil, what is it required for, what is it made of and how exactly does it differ from paintwork?
In addition, there is a special category of oil that is used in saunas and baths. What does oil give to wood?
Oil will act as an impregnating material. ...
After a certain number of cycles of moisture absorption and drying, the wood begins to crack and deform. To prevent this from happening, it is recommended to process wood products from time to time with a special oil composition.
Deeply absorbed into the wood structure, the oil begins to fill the treated wood material with substances that prevent the penetration of water, dust, abrasion, and external temperature influences. It perfectly protects against household pollution, spilled juice, water and coffee.
In addition to protective properties, the oil helps to improve the aesthetic properties, and after impregnation with the oil composition, the structure of the wood begins to clearly appear, and the natural shades are also enhanced.
The oil contains coloring elements that can completely change the original color, and imitate the shades and colors of other wood species.
Surface treated with fashion oil to retain the natural grain of wood. Due to the presence of natural ingredients (carnauba wax and beeswax), the oil helps to provide excellent resistance to mechanical stress and abrasion. At the same time, the applied coating dries quickly after application, and also has a pleasant and light odor.
These are linseed, sunflower, core, soy and tung oils.
An artificial component is also used,
, namely tallow oil.
It forms a film very quickly on contact with oxygen. It is considered to be one of the best components for wood processing, and it is not used in its pure form, only after prolonged heat treatment.
This is a feature of the oil, in which leticin will act as a wetting agent in contact with solids, and also allows the oil to penetrate deeply into the wood structure.
There are no synthetic analogues of this type of oil in nature, and it dries many times faster than linseed oil. The resulting water-repellent film is much stronger, even with a large layer application.
Please note that wax, colors and wax solvents are often added to the oil. Such mixtures are capable of carrying aesthetic and protective functions.
They are perfect for highlighting the natural structure and even imitation of other, more expensive types of wood.
Wood oil or varnish can be found in any building market. By the way, on sale you can find ready-made compositions of wax and oil, and it is also not so difficult to prepare them yourself at home. You will need to take linseed oil, a small amount of rosin, beeswax, and white alcohol is allowed as a solvent. For items of children's furniture, toys made of wood, wooden dishes, it is worth using just such mixtures.

… there will be protection from outside influences. The main difference is that the paint and varnish material forms a film on the surface of the wood, and the film will determine the visual effect of the paint and varnish composition, and it can be glossy, matte, semi-matte and semi-gloss. It turns out that the protection by the varnish composition of the products, which are made of wood, is carried out only from the outside.However, the protective film that is obtained through the use of varnish will visually transmit traces of abrasion and damage more visually.
The varnish can contain many synthetic components:
Alkyd varnish for wood is one of the most popular varnishes that are used for wood processing. It is based on alkyd resins, fatty acids and vegetable oils. By the way, alkyds prevent sticking. The varnish is perfectly able to withstand temperature changes and heating up to +250 degrees, and can also be used for heated wooden or parquet floors. The most common name for such a composition is yacht varnish for outdoor woodwork.
It will be 12 to 24 hours or more. By the way, the varnish itself has a pungent smell and is quite toxic. When used indoors, special respiratory and eye protection should be used. Alkyd resin solvents, when evaporated, can act as a severe irritant to the mucous membranes of the mouth, eyes and nose, as well as cause chemical burns. In order not to "wrinkle" the varnish film after 100% drying, it is recommended to adhere to the rate of consumption no more than 0.
12 kg per 1 m 2 .
First, we suggest considering a couple more types of paints and varnishes. Polyester varnish is made on the basis of polyester resins. This is a type of multi-component type varnish. Polymerization is carried out due to the passage of a chemical reaction between the components that enter it, and not due to solvent evaporation as in other types of varnish.
When drying is complete, a highly glossy surface is obtained.
The lacquer has excellent wear resistance. It is used to make musical instruments. It is a synthetic compound, saturated, making it toxic. For internal work, such a varnish is definitely not suitable, and, as a rule, it is used for external work.
The polymerization period will be 12 to 24 hours.
Polyurethane varnish can be of two types, one-component and two-component. The first types of varnish are used for outdoor work, and they will be ready for use without prior preparation. But two-component are used for internal work, and here you will need to mix the components in advance before applying.
Please note that the polyurethane two-component varnish should be mixed in small portions, and after mixing, the paint and varnish composition will need to be fully used, because it will otherwise dry out even in an airtight container.
We also do not recommend using such varnish for the production of items of furniture for children due to the presence of toxic components. The fact is that polyurethane varnish has a strong aroma, and when applying varnish, you should definitely use personal protective equipment. It also does not accumulate static electricity, and after completely drying it will not leave a harsh aroma.
Alkyd-carbamide varnish is one of the varieties of two-component paints and varnishes, which are based on amino-formaldehyde and alkyd resins, which dissolved in an organic solvent.
For the drying process, it is diluted with an acid-type hardener before actual use.
Often such varnish is used for the internal type of work on wood, and after drying, a wear-resistant and durable film is obtained. The resulting surface is moisture-resistant, frost-resistant and not as flammable as its counterparts. Such varnishes are advised to be used in rooms where there is a high degree of traffic.
Apply them by means of any painting tools, namely:
Due to the formaldehyde in this type of varnish, increased safety measures should be used. For example, after complete drying, formaldehyde will disappear within 3 days.
At the moment, water-based paints and varnishes are becoming increasingly popular. Such varnishes for wood have almost no aroma, and they are also called quick-drying.
The advantages are the following:
- There is little time for complete polymerization (drying).
- Non toxic.
- Do not possess aroma, unpleasant odor.
- Do not change color during use.
Please note that water-based paints and varnishes can be two-component and one-component. The former are more stable and are used for rooms with a high degree of traffic.
In order for varnishes to look beautiful and serve for a long time, a special temperature regime should be observed during application. The optimal temperature will be at least 25 degrees, and it is also undesirable for there to be drafts, drying should be natural, without forced heating with heat guns.
Coating the surface with varnish is done in several layers, and a high level of humidity is also not allowed, because in such conditions the varnish can begin to swell. Varnishes are produced in plastic and metal containers for large and medium volumes of work. In addition, there are varnishes in aerosol cans for decorative, restoration and small volumes of work.
If we talk about what is better - oil or varnish for wood, then the victory will be with oil. Let's see why.
To ideally apply varnish to wood, you will need a spray gun, through which the paint and varnish composition will need to be sprayed in an even layer on the surface of the product. In this case, you can apply a lot of varnish, but then there will be smudges. And no special equipment or even tools are required to apply oil. A clean piece of linen or cotton is required. The oil is applied in excess, and when the wood has absorbed its own, the excess can be removed.
Also, varnish is difficult to apply in an ordinary workshop, and no matter how hard you try to keep the room clean, there will still be dust and wood processing in the workshop, and if dust gets on the surface when solidifying, it will ruin the appearance. In the case of oil, you can sprinkle the product with shavings and wood dust after application, and then remove everything with a regular rag with excess oil, and there will be no problem.
After hardening, the varnish creates a hard crust on the product, and when we touch the wood that is covered with varnish, we touch the varnish itself, and not the wood, which means there will be no warm and pleasant sensation from the touch. The oil works differently, and does not create a crust, but is absorbed into the top layer of the wood, closes its pores, and when you touch, you touch the wood itself.
