Application of the lacquer is the final stroke to the parquet floor. Treatment lacquer has favorably affect the final operating properties of the coating. The parquet floor is designed for sufficiently long operation. Therefore, even its high cost is usually paying off a long service life. As for the lacquer coating, it largely depends on it, how the parquet looks like, and how long he can serve. Therefore, if you cover a parquet board with a material of low quality, you can spoil the natural appearance of wood.

Classification of varnishes for parquet board
Varnish coating causes not only aesthetic, but also a protective function. So, it protects the floor from mechanical wear, various damage, and excessive moisture. A high-quality lacquer coating allows to emphasize the beautiful structure of wood and give it various color shades. In addition, this coating usually withstands the polishing process, and does not lose its properties.
Parquet varnishes can be classified according to several parameters:
- In physical and chemical properties. Under them implies the following characteristics of the material: turnover, viscosity, the recommended method of application to the surface of the parquet, etc.
- In appearance. According to this gradation, varnishes can be completely transparent, which, after applying, do not change the appearance of wood, or have a specific shade transmitted by the tree. Currently, manufacturers offer a large color palette and material shades.
- According to the degree of resistance. Specialists share parquet varnishes in terms of mechanical resistance, as well as resistance to direct sunlight.
- According to the degree of gloss covered with the surface. Under this feature, this material is permissible to divide on glossy, semi-man, lacquer parquet matte, semi-bright, and silky matte.
- By chemical station. On this basis, the mixture is divided into:
- polyurethane,
- alkyd
- acid-curable,
- uretanquid
- primer
- water-soluble
- formulations on an anhydrous basis,
- mixtures for parquet, based on formaldehyde resins.
Last feature, all commercially available parquet varnishes are divided into three main categories: anhydrous, water-soluble and acidically rejected. As the basis for anhydrous parquet varnishes, artificial oil resins are used. As part of acid-renovated mixtures, there are several types of formaldehyde resins.
Often the buyer wonders what parquet varnish is better to choose. To know the answer to him, first of all, it is necessary to understand the technical characteristics commonly specified in the lacquer description.
Varnish parquet lacquer
This material is made on a water basis. It differs in the absence of solvents, or their insignificantly small fractions in the composition. It is this fact that makes it more environmentally friendly, which means less toxic and, accordingly, not so harmful to health. This varnish practically does not smell, so work with him is not as dangerous as with other species. It is also most suitable for premises in which people who are prone to manifestation of allergic reactions, or children will live. In addition, it is not susceptible to burning, which makes it indispensable for use in fire hazardous premises.
It is worth noting that water-based lacquer is not deprived of the flaws:
- So, it is distinguished by low wear resistance. But this problem is solved by many manufacturers by adding special additives to products.
- It is also worth noting that the mixture for water-based parquet has strict requirements for storage conditions. In particular, it is not recommended to keep it at negative temperatures. When working with it, the temperature in the room should also be maintained, which should not be higher than 15⁰s.
To apply this material to the parquet, it is recommended to use a low pile roller. At the same time in the room where the repair is carried out, the humidity must be at least 50%. Water-based mixtures are often sold along with the primer, which is applied to parquet boards. The primer allows you to protect the edges of bars from warping, which may occur when the moisture can occur on their surface.
Lucky, made on a water basis, are not recommended for applying for parquet from beech, pine or ramp. If this mixture is freezing, it will become unsuitable for use. In addition, the coating made on the basis of this varnish is short-lived. This material usually requires a lot of time to dry. So that the coating finally opened, it is required that the room is ventilated, i.e. So that there was a permanent influx of air. It should be borne in mind that water-bearing varnishes can make wood color more intense.
Solvent-based parquet lacquer
Another name is alkyd. If you compare them with varnishes on a water basis, they do not have adhesive properties. Therefore, if it falls into the gap between the boards, the gluing will not happen. When using such a material, it is necessary to take into account its ability to change the color of the wood to which they are applied. It should be remembered if you need to keep the color of the tree close to the natural species after the coating of varnish.
Of the shortcomings of parquet alkyd varnishes, it is possible to note the fact that they are very sensitive to the conditions of drying. Therefore, if the mixture is left to dry indoors with an increased temperature, it will dry up long enough. Therefore, the temperature will have to be artificially reduced. In addition, the alkyd lacquer cut, it is necessary that fresh air fall into the room.
The disadvantages should also include the fact that it cannot be applied to a thick layer. If the thickness of the mixture layer is too big, it may cause formation on the surface film of visible wrinkles. Low wear resistance is also one of the main disadvantages of this material.
Anhydrous varnishes
One of the most popular species of this material are anhydrous urethane parquet varnishes. Their high wear resistance allows them to recommend them to use indoors, where the surface is often exploited. In addition, they can be successfully applied in rooms where there is a chance of a chemical influence on the floor. It should also be noted the following advantages of such varnishes:
- The ability to maintain the authored natural color of the parquet material.
- Weak sensitivity to the microclimate indoor.
- Resistance to moisture falling on the surface.
- The lacquered layer is capable of resolving abrasion and withstand more loads for a long time.
Today, we sell both single-component and two-component polyurethane-based mixtures. They may contain different aromatic compounds. As the basis of such mixtures for the parquet can be acrylic, uretan or solvent.
In general, polyurethane itself is quite durable material. Therefore, the lacquer, which is done on its basis, is used as covering parquet boards in the rooms, where the day is quite crowded.
Single-component polyurethane varnishes are usually marked with three letters - PUR. They are easy to use so that even unprofessionals can use them. They are sold already in the form, ready to use. Two-component polyurethane parquet varnishes are marked with two letters - DD. To use them, you must first prepare correctly, which requires knowledge of some nuances. Nevertheless, these mixes are much stronger. And it is they used by professionals.
The varnish made on the basis of solvents is characterized in that after applying, the solvent evaporates first. Next, the mixture is hardening.
The disadvantages of parquet varnish polyurethane can be attributed to the fact that if it is exposed to moisture when applied, it will lead to its foaming. The same can occur when moisture in the dry varnish. In addition, these mixes after applying glued the planks.
Mixtures of acid rejection
Such mixtures in particular include two-component parquet varnish. Buying them today without problems. They have the highest wear resistance. Due to which they are recommended to be used to cover the surface, an input load. Mixing two-component parquet varnish with a hardener must be produced in proportions 10: 1.
Two-component varnishes perfectly tolerate temperature fluctuations and sharp jumps of indoor humidity. After their application, the color of the parquet can be brighter natural. It is necessary to work with this material with the use of glasses and respirator. This is due to the fact that such a varnish distinguishes a large amount of toxic substances into the air, the fall in the body can harm him. The room in which work is underway with this group of mixtures should be well ventilated, and after three days, there will be no trace from the smell.
Today, a rather popular acrylic parquet varnish. Its advantages include the absence of smell, economy, lack of excretion of harmful substances. In addition, it does not require hardeners, quickly dries and goes well to almost any surface.
Formaldehyde varnish
These types of parquet varnishes are distinguished by excellent resistance to external influence. At the same time, this material has all the qualities needed for the parquet board. It is recommended to use indoors that are often visited. This varnish has a very good clutch with wood, and does not require preliminary application on the board of special primer. In addition, it is characterized by high resistance to moisture and temperature drops. You can apply this varnish to almost any instrument suitable for this purpose.
Despite many advantages of formaldehyde varnishes, he has its drawbacks. First of all, they possess a very pronounced sharp odor. Therefore, when working with them, the room should be well ventilated. In addition, this varnish can glue the ends of individual, located next to each other with parquet flooring.
Laco primer
Such mixtures dry less than other types. They are used to give wood of certain decorative qualities. It is used in the following cases:
- The need to give a parquet one-photon surface.
- If necessary, it is necessary to neutralize the adhesive effects of the main varnish.
- To prevent the exit to the surface of wooden bars of oils and resins.
- To absorb moisture in the junction between the boards.
When using the mixture, which includes the main component of the primer, its main coated compatibility is important. At least two layers are applied.
Parquet varnish: What is better?
This question, perhaps, can not be answered unequivocally. To determine the type of varnish, it is necessary to clearly understand which conditions operate conditions for the operation of sexual coating. So, if environmental friendliness and aesthetics are priority, then universal water-based varnishes are best. They practically do not smell and differ in high levels of adhesion. More such mixtures are resistant to external influence. If you want to buy parquet varnish and save, but at the same time make high-quality finish, the best choice will be a two-component polyurethane parquet mixture.
When parquet varnish is selected, you need to take into account some nuances. For example, the ability of varnish to reflect light. It depends on the number of the passive component in the composition of the mixture. It is believed that the more this component, the surface of the floor will be more matte. Another important feature of the coating is wear resistance. The most resistant to Chem. Substances are acrylic varnishes. At the same time, they do not differ good resistance to abrasion. Polyurethane varnishes are considered the most durable, but they have a harmful and sharp smell, so they have toxicity. This requires special conditions for working with them.
Whatever parquet varnish is in the end is selected, the most important thing is to comply with all the basic instructions when using this material to cover the parquet floor. Compliance with the basic rules when applying parquet varnishes will make your gender beautiful and durable.
