- polyurethane,
- acrylic,
- polyurethane water-based.
Each of them has different properties, so before you cover the furniture with varnish, you need to devote time to selecting the most appropriate option.
Oil ↑
Such compositions are initially produced on the basis of natural resins, but then they started to add artificial components with natural oils. It is possible to reduce the manufacturing costs of these products and make it affordable for most buyers.
But after creating more modern types of oil paints began to be used for flooring, so despite the low price, they should not be put on the furniture.
Alkyd ↑
This type is most common and is a solution having in its composition a synthetic resin and a solvent. Films of such compositions are transparent and solid. When applying them on the tree, its color almost doesn’t change. In addition, these coatings have good adhesive properties and capable of resisting the effects of moisture.
Sometimes this kind of formulations referred to as oil, but this is not true, since their production involves the use of other substances. At the same time the properties they are superior to the varnishes described above.
Spirit varnishes ↑
This kind of coatings for furniture made from natural resins and alcohol and has the following features:
- good adhesion,
- mechanical strength,
- high Shine.
With all these advantages they have a fairly serious drawback – the instability to moisture. They are used for coating different wooden surfaces that need polishing.
Alkyd varnishes keramzitnye ↑
This type of coating dries only after entering the acidic curing agents immediately before application to the surface. But it is worth remembering that after this, the varnish can be used only for a short period of time, after which it loses its properties.
This varnish forms a very solid film, characterized by high wear resistance and ability to resist the effects of moisture. The presence of these characteristics allows the use of lacquer not only for furniture but also for parquet.
Polyurethane varnish ↑
Such coatings are characterized by high strength and resistance to mechanical wear. Because of this it is often used for flooring. The high price of the varnish is justified by performance characteristics. But when applying, should carefully read the user manual to prevent errors. The same group developed and water-based.
Properties of water-based lacquer for wood ↑
For wood furniture is suitable varnishes that is water-based. Solidification of the composition occurs as the evaporation of the liquid. This way, during the whole process there is no smell.
The water-based paint has the following features:
- sustainability,
- less drying time,
- uniform distribution on the surface and no change in color.
But this nail Polish has a limit – it should not be used on hygroscopic surfaces. One of the main features for water-based coatings becomes reducing the sharpness of the texture, thereby hiding a lot of flaws.
Transparent or colored ↑
The most popular are transparent coatings, which are used for furniture made of expensive wood. This allows to keep the natural texture of the material. Colored lacquer is applied to less valuable wood and performs the following functions:
- to protect the surface from damage,
- color enhancement,
- the creation of a more attractive appearance.
There are many nail colours, so the choice depends on the preferences of the owner restored furniture. When buying you need to consider the depth of penetration of the composition, as well as the level of brightness than its smaller, the lighter the surface.
Increasingly popular white and black color. The first one is suitable for light wood species, while the second is able to give furniture a rigor and a special gloss.
Matte or glossy ↑
To the surface of the wood look more natural, you should pay attention to Matt varnish for furniture. When using such a composition, it is worth remembering that after application the surface should be sanded. But if you select this option, the owner of wood products will be pleased with its appearance, as the varnish contributes to the concealment of faults. The care of furniture with such a coating is simplified.
If the room is dark enough, you should choose a glossy varnish. It will provide not only surface gloss but also accentuate the beauty of wood surfaces. But it is worth noting that the damage on it is more noticeable than on the matte.
