Lacquer for parquet what to choose

Respectable parquet flooring requires special attention. If the plank floor can simply be "covered" with paint, then the parquet should be covered with varnish or special wax( or oil), otherwise it will quickly lose its attractiveness. In addition to the aesthetic purpose of the lacquer coating, it serves as a good protection for the board, without which the service life of the parquet is significantly reduced.

Lacquer for parquet what to choose

Lacquer for a parquet what to choose - such question arises at owners of habitation in which the parquet board is stacked. In addition to varnishes, there is a wide selection of different compositions for the protection and transformation of wood in the assortment of building stores, but nevertheless the varnish, like the most reliable and -tested , is the most popular today.

Varnishes for parquet can have a different basis, so before you choose the , you need to familiarize yourself with the characteristics of some of them.

Choosing the varnish for parquet, nzhno take into account the type of wood from which the board is made, since it can be bright and dark shades, so the nail must match its color. In addition, each of the rocks has its own density, and this property of the material depends on its absorbability .

The design of the room is also of great importance when choosing a varnish, in the is laid with parquet, that is, the traffic intensity, humidity and load types with which the coating will be exposed. If the varnish will be used to cover the floor in the room of an ordinary apartment, where a small family lives, there is no need to choose a varnish capable of withstanding heavy loads.

But in such conditions, you need to consider a particular room. For example, for a hallway or a kitchen, it is better to purchase varnishes with the possibility of experiencing higher loads, as these rooms have greater patency and are more often cleaned. Therefore , in this case the protective properties of the composition should be by an order of magnitude above.

A high-quality varnish coating should also emphasize the beauty of wood, and serve as a reliable protection for it

High-quality varnish should emphasize the beauty of wood and serve as a reliable protection for

. For public buildings and rooms with a high intensity of human flow, attention must be paid to the strength of the varnish, since it will have to withstand the mechanical impact from numerous heels and brought on shoesdust and dirt. In such places, oil impregnations or strong water-repellent compounds are often used to help keep the parquet cover in the with the proper condition for a long time. Moreover, such a floor is easier is amenable to update, unlike lacquer coatings. Therefore, varnish is rarely used in this case.

It should be remembered that that inexpensive compounds are not particularly durable and will last no more than 2 ÷ 3 years, and considering that the process of applying - varnish is a laborious task, it is better to choose at once reliable will keep the floor in its original state for 12-15 years. Naturally, the AS on at times is higher, but using it, you can save yourself from many problems for a long time. These varnishes are two-component compounds.

You do not need to think that the material produced by abroad will be necessarily more qualitative and durable. First of all , you need to pay attention to the chemical composition of the lacquer, and not the country in which it is released. Some imported products are not of high quality, have an unpleasant smell, dry for a long time and are quickly erased.

It is very important to pay attention to the consumption of the composition. For example, five liters of high-quality lacquer should be sufficient for covering three layers of area in 15 ÷ 17 m², in two layer 20 ÷ 25 m², it can be stretched to 30 m² of room, but layers of will have thinner ones.

Also , you need to pay attention to capacity , in which is sold varnish, because quality compounds are never sold in wholesale packaging or plastic buckets - is usually so packaged for imitations of imported varnishes by well-known manufacturers.

The varnish must be packed in cans or plastic jerricans with volume of not more than 5 ÷ 10 liters. If this is a two-component version of the varnish, then the fixed is added to the main packaging. They are mixed with each other in the strict proportion indicated on the packaging, immediately before application to the parquet.

So, when buying a varnish, you need to pay attention to the following characteristics:

  • Varnishes for parquet are produced on different bases - urethane-cured , alkyd, polyurethane, formaldehyde and water. These parameters are indicated on the packaging in the chemical composition section.
  • The material can give a coloring effect or be completely transparent and preserve the natural color and texture of the wood.
  • Depending on the consistency, the varnish may be viscous or flowing - from this parameter the way of its application to the surface will depend.
  • Composition can give a variety of aesthetic effects - matt , silky matt, semi-dry or semi-gloss and glossy.
  • In addition, the package indicates susceptibility to moisture, resistance to stress, durability and an approximate service life.

Types of varnishes for parquet

To make the right choice, you need to know what each kind of varnish is.

Primer varnishes

Priming compound for further varnishing of parquet

Primer for further varnishing of parquet

The name of such varnishes in itself indicates that their purpose - prepares the surface for the layers of the finish coat. Primer varnishes impregnate wood, and this promotes better adhesion when applying the following, basic layers of .If the parquet is treated with primers, the quality of the face coating improves several times. But in addition, the use of such a starting treatment contributes to:

  • reducing the adhesive effect of the upper layers of varnish at the junctions of individual dies;
  • creating an ideally smooth surface and highlighting the invoice pattern of wood;
  • protection of the surface and side parts of the plates against possible exposure to moisture;
  • preservation of natural protective oils of valuable wood species .

Primer varnishes are selected depending on the basis on which the finishing coat will be made, as these compounds should be compatible with each other and have good adhesion.

The primer should ensure a high adhesion of the floor surface to the forthcoming application of varnish

Primer should ensure high adhesion of the floor surface to the forthcoming application of

varnish. If the materials are incompatible, the work will be completely damaged and its will have to be reworked as a surface will be covered with bright spots. You can fix this trouble only by removing the varnish or by cycling completely all the floor.

For example, if a waterborne lacquer is purchased for the finishing finishes, then the primer should be exclusively waterborne - then the parquet will have a smooth and reliable coating.

It is very important that still has and the fact that the surface covered with a primer has a property that absorbs the finish lacquer less, and means , it significantly reduces its consumption.

The primed parquet will less absorb the varnish at the finish application

The primed parquet will absorb the varnish less at the finish application.

Primer varnishes made on different substrates dry quite quickly, as some of them are absorbed into the surface of the parquet wood, and the remaining surplus quickly evaporates. The drying time of the first primer layer is from 20 minutes to 3 ÷ 4 hours.

To achieve the desired result and get a beautiful surface, the masters recommend using a priming and finishing compound made by one manufacturer. This is due to the fact that the composition of these varnishes is designed for full compatibility with each other, in fact, they represent a single "system", therefore they have excellent adhesion, they will never go into any "undesirable reactions".Choosing the same compositions of different firms, you can get an unpredictable result, which is unlikely to please.

Water-based varnishes for parquet

Water-based varnishes - are the most popular because they do not have an unpleasant odor and dry out quite quickly. When choosing such a material, it is better to purchase two-component compositions, since they dry out give a more durable moisture-proof coating than single-component solutions.

Some of the most popular are varnishes for water-based parquet

One of the most popular - water-based varnishes

This varnish includes in its composition microscopic particles of solvent and emulsifiers mixed with water, so it dries slightly differently than materials on other substrates. After the formulation is applied to the primed surface, water first evaporates from it and only then - is a solvent that passes through the concentration process before evaporation. Further, after its evaporation, solid and a strong film are formed on the parquet surface.

Water-borne varnishes can be divided into three categories according to the content of solvents in them:

  • , the first of which can be referred to as compositions where this component is completely absent;
  • to the second category are water-based varnishes having in its composition of not more than 5% of the solvent;
  • The third category contains a solvent of 15% .

All three categories of lacquers, regardless of the amount of solvent in them, have good adhesive properties with wooden surfaces, so they are great for both solid boards and parquet.

It should be said that water-based varnishes must be applied necessarily on the primed surface of the parquet, in order to avoid the penetration of varnish between the dies. Moisture, hitting between them, can be absorbed by the wood lead later to the appearance of creaking in the parquet. By the way, according to many masters, in general should not use water-based varnishes for parquet floors, since there is always the risk of an unpleasant squeak, even if a primer was previously used.

There are some other significant drawbacks to these varnishes that you need to know about when purchasing material:

  • One-component aqueous lacquers, consisting of water, solvents and emulsifiers, have a low wear resistance, so they quickly wear out. Two-component varnishes have a longer service life and perfectly protect the wooden coating, but provided that such a composition will be applied to the in a room where the humidity is 50%.Such an atmosphere in the rooms can not always be achieved, especially in the winter, when heating works.
  • To the surface after the drying of the water-based varnish was smooth, it must be applied using a roller, since tampons, sponges, spatulas and even brushes are not suitable for this process.
Water-soluble varnish should only be applied with a roller

The water-soluble varnish should be applied only with the

roller. To the expressed positive qualities of water-based varnishes, one can attribute their properties:

  • The absence of unpleasant sharp smells, such as from varnishes made on organic solvents -, this factor particularly attracts apartment owners with a small volume space. However, one should not think that the lacquer absolutely does not smell - it all is equally present, but not so strong and sharp as in the other compositions.
  • Varnishes that are water-based are not flammable, therefore they are used in rooms where it is forbidden to cover surfaces with fire-resistant compounds based on flammable substances.

There is yet one secret, which is not bad to learn before buying a water-based varnish. If a professional varnish is purchased, it is possible to apply it to the on the unprimed surface. If on the package there is no indication of the "professionalism" of the category of a particular composition, then the treatment of the floor with a primer before applying it is necessary.

Alkyd varnishes

Alkyd varnishes are produced on the basis of resins obtained from natural raw materials, by , by transesterification of vegetable oils, glycerol and rosin, alcohols and acids. Due to the presence of oils in their composition, the varnishes have the ability to be absorbed into the structure of the tree, thereby creating its reliable protection against external mechanical damage and the effects of moisture on it.

Alkyd varnishes, perhaps, have more shortcomings than merits

Alkyd varnishes, perhaps, have more drawbacks than the advantages of

Alkydic compounds also contain quite toxic substances, such as white spirit, so when buying this product for parquet, you must choose the composition with the lowest concentration of this substance. Like any other varnish variant, the alkyd has its positive qualities and negative, which you need to know about by purchasing this product for finishing the parquet.

Glossy and semi-glossy, semi-matt and matt are produced. The types of alkyd varnishes from of which can be chosen one, which is more suitable for a particular parquet.

The positive properties of alkyd lacquers include:

  • Deep penetration of the substance into the structure of the surface to be coated.
  • Alkyd composition increases the texture of the wood, giving it an aesthetic appearance.
  • The varnish has a viscous consistency, so it does not become dirty between the dies, and means , after drying the coating there will be no creaking when walking on the parquet.
  • It is not affected by changes in temperature and humidity, and also has a high resistance to mechanical stress.

The following are the negative properties of compositions:

  • Application of on the surface of the varnish dries long enough and requires special drying conditions.
  • Drying of varnish must be carried out at not too high temperatures, as this process can be delayed, so when film is formed on the varnish , it is best to create a small draft by opening doors and windows;
  • Since the consistency of the varnish is sufficiently thick, during the application of it to the surface it is necessary to carefully monitor the thickness of the layer, otherwise on drying, in places where the layer is thicker, wrinkles can form;
  • Alkyd varnishes are characterized by rapid abrasion, therefore often the coating will have to be updated .In a word, this kind of varnish is more suitable for furniture than flooring.

If you want to get a high-quality and durable parquet coating, then it's better to give up alkyd varnishes, despite even on the fact that they also have certain advantages, which have already been mentioned.

Polyurethane varnishes

Polyurethane varnish is excellent for rooms with high traffic intensities, as it is extremely wear-resistant, and has high adhesive properties. This type of parquet coating material can be single- and double-component, and has the markings PUR and DD.

"Чемпионы" по износостойкости - полиуретановые лаки

"Champions" for wear resistance - polyurethane varnishes

Polyurethane varnishes can be manufactured on different bases - is urethane or acrylic. Depending on the basis, the compositions have different smells, but all of them, unfortunately, are not very pleasant. Since there is no water completely in the polyurethane lacquer, it dries much faster than the water-soluble variant. The solidification of this varnish begins with the evaporation of the solvents that make up its composition. Then the chemical process of polyaddition takes place, as a result of of which the varnish solidifies.

After hardening, a coating of exceptional durability

After hardening, a coating of exceptional durability

is obtained. During the application of the compound to the parquet, as well as when it dries, it should not be allowed to come into contact with water. Wood parquet should have a moisture content of not more than 6 - , if it exceeds this figure, but the work can be damaged by the appearance of air bubbles, detachment or even foaming. As a result, the defects will be clearly visible on the surface of the parquet.

Polyurethane lacquer composition, like all the others, has its advantages, but it has almost no negative qualities.

To the positive moments in the polyurethane composition the following are considered:

  • After the coating hardens, it becomes moisture-resistant, as it forms a kind of film on the parquet surface.
  • The film formed is quite elastic and does not tighten the surface structure of parquet wood.
  • This coating does not require preparation of the parquet surface with primers.
  • Coating after curing and polymerization does not react to changes in temperature and humidity in the room.
  • Parquet, coated with polyurethane lacquer, excellent is protected by from mechanical influences and abrasive loads.

We can say that this varnish has one significant drawback of - if it falls into the slots of the parquet, then it glues together its individual elements, that , in fact, is undesirable for such a coating.

Otherwise, the polyurethane varnish version can be called the best for parquet coating, as it is suitable for rooms with any intensity of loads.

Formaldehyde varnishes

Also available are parquet two-component varnishes, one of which is an acid or formaldehyde hardener. Such varnishes are considered to be the most resistant and reliable .

Two-component acidic parquet varnish

Two-pack acid parquet lacquer

However, even the very name of the composition frightens, since such a substance as formaldehyde is dangerous for human health.

It should be noted that this element in the varnish plays the role of hardener. When the lacquer is completely solidified, no longer has and the trace of this dangerous component. In the process of solidification, formaldehyde volatilizes, therefore it is necessary to work with this varnish with the mandatory use of respiratory protection( in the respirator), and the should be dried with open windows.

The coating turns out to be excellent, but special precautions

The coating turns out to be excellent, but special precautions should be taken during operation.

The advantages of formaldehyde varnishes are as follows:

  • They have excellent adhesion to wood;
  • It is possible to apply varnish to any tool that is convenient for the master.
  • This coating does not require preliminary priming, which allows to save on preliminary processing of parquet ;
  • The material has high resistance to jumps in humidity and temperature ;
  • This varnish coating is wear-resistant to all kinds of loads.

Negative properties of varnishes on formaldehyde:

  • This kind of varnish easily flows into the gap between the plates, since it has a liquid enough consistency of ;
  • The composition initially has an unpleasant, pungent smell, high enough toxicity, therefore will have to take precautions when working on its application.

When making a choice of a specific varnish for coating parquet, it is already right in the store to get an additional consultation of sellers, carefully study the annotation located on the package. Based on the characteristics that this publication has introduced to you, it will be easier to understand the subtleties of choice and make a really successful acquisition.
