Adhesive for gluing block parquet maple. How to glue parquet with your own hands

Yes, frankly, there are enough parquet adhesives on the market to get completely confused if you don’t understand it. Therefore, we will try to give you clear recommendations so that you are not deceived by either parquet floor workers or illiterate sellers. How many times do we hear the same questions when entering into a dialogue with a client:

What glue should I buy for plywood?
- How to glue a solid board?
- what to lay block ash parquet on?
- and many others...

Groups of parquet adhesives, according to their purpose

Solvent-free dispersion adhesives or water-based suitable for untreated oak parquet up to 15 mm thick and cork backing. The second purpose of these adhesives is for gluing plywood onto concrete base, also when diluted 1:1 with water as a primer for application on cement screed. As a result, this group of adhesives has very limited applications. Sanding no earlier than after 7 days.

Solvent based adhesives include rubber and artificial resin-based ones. They can be used to glue multi-layer varnished parquet boards, piece parquet made of oak, ash, beech or maple up to 22mm thick and some exotic species, plywood on a cement screed. Sanding after 4-5 days. These parquet adhesives do not change the moisture content of the wood and are not susceptible to frost.

Two-component polyurethane or epoxy-polyurethane adhesives are the most universal, suitable for any base, regardless of the size of the parquet plank or solid board. Polyurethane adhesives contain neither water nor solvents and can be used with virtually no restrictions. It has a limited processing time in the finished state from 40 to 90 minutes, sanding and varnishing after 1-3 days. Epoxy-polyurethane adhesives have less elasticity than polyurethane adhesives, are quite durable, work time ready mixture 2 hours. Relatively inexpensive, they are easier to work with during installation, but are more toxic for parquet floorers. Some types of this parquet glue produced without solvent. They are used practically without restrictions in parquet work and for laying plywood with and without screws.

One-component polyurethane adhesive, can be used without restrictions on all types of wood, cures by absorbing atmospheric moisture, and is easier to work with than two-component adhesives. The disadvantage is that if there is insufficient humidity in the room, the glue does not set well. Contains neither water nor solvent. Sanding after 4-7 days.

Parquet adhesives based on MS polymers or silane adhesives - the most elastic of the above. They are used for treated and untreated types of parquet, have increased sound insulation, and are suitable for heated floors. They have limitations in application based on the width of the board. Has good adhesion for exotic species. Cures due to atmospheric moisture. Sanding after 3 days.

Hybrid adhesives are made on the basis of silane-modified polyurethane, are elastic and quite durable. They can be used with virtually no restrictions for any type of parquet or plywood installation and contain neither water nor solvent. They cure upon contact with atmospheric moisture and are completely cured in 3-4 days.

Primers for glue They are applied to absorbent and non-absorbent substrates and have different compositions and penetrating properties. For example, epoxy primers are applied to porous screeds to increase their strength and for waterproofing with a residual moisture content of 6-8%, dispersion primers only remove dust from the base, polyurethane primers are applied to any surface, even completely smooth ones.

Correctly selected adhesive for parquet concrete screed, as well as compliance with the installation algorithm will allow you to obtain a strong, stable and durable coating. There are several ways to install a parquet floor on a concrete base: with and without plywood backing. What are their differences and in what cases can you not do without a plywood layer? More on this below.

As in any other matter, laying parquet on a concrete screed has its own rules and subtleties.

The first and basic rule is that parquet is laid on a concrete screed only with a sufficient level of preparation of the latter. This means that installation can begin no earlier than a month after pouring the concrete floor.

The second and no less important rule is that steam and waterproofing layers must be placed between the concrete base and the parquet board. An additional plus is the installation of a layer of insulation.

Rule three - during the installation of a parquet floor, it is allowed to use bitumen mastic, which plays the role of a primer and waterproofing at the same time. The parquet board is attached to a layer of glue, selected to compensate for the difference in linear expansion of the material, base and screed.

It's better to take your time and do everything right than to regret the result in the future

What adhesive mixtures are used?

The adhesive on the market for parquet on concrete screed differs in composition and characteristics. The following varieties are distinguished:

Dispersive.
Solvent based.
Reactive hardening.

Dispersion compositions are distinguished by their affordable price and high hardening speed. For styling parquet board or piece parquet This type of glue is not suitable for bases with exotic wood. But for classic options- beech and oak - quite.

The mixture dries in no more than five days, and this period is considered the maximum. After the glue under the material has dried, a few days later you can proceed to the final stage of finishing.

You cannot treat the surface of a parquet floor immediately after installing it with glue.

Mixtures in the base with a solvent allow you to quickly make changes to the actions within 25 minutes after fixing the board. The glue also dries in no more than 3-5 days, after which you can sand the floor.

Reactive hardening adhesive is the most modern version, is expensive and is created on the basis of one-component or two-component polyurethane glue. The mixture is suitable for installing both parquet boards and parquet, regardless of the type of wood. You can proceed to final surface treatment after two days.

How to properly attach a board to a screed with glue

In order for laying parquet boards with glue to meet expectations not only in terms of the aesthetics of the finished coating, but also in terms of practicality, durability and functionality, you must follow the installation rules.

In addition, before starting work, it is necessary to calculate the amount of material for the flooring, assuming a small reserve in advance. The minimum reserve is considered to be 3% of the parquet board and this is when using simple option laying - deck. Before installation, the material is delivered to the site at least 2 days in advance, without unpacking, giving the tree time to adapt to the new conditions.

Depending on the floor configuration, the parquet stock can reach 15%

The adhesive mixture is selected depending on the requirements for drying speed and quality of fastening, taking into account the cost and manufacturer.

So, laying on a screed with your own hands will require the use of the following tools:

hacksaws;
hammer;
roulette;
hammer drill;
spatula (with a serrated surface);
restrictive wedges;
tamping block.

You will also need materials:

parquet board;
plywood (provided a plywood backing is installed);
adhesive sealant;
nails;
parquet glue.

It is advisable to study the entire installation process in advance and select the necessary tools.

The installation process is carried out in the following order (consider the option of laying on plywood):

A layer of glue is applied to the concrete screed (must be dry, clean and level) with a spatula, after which sheets of plywood are laid, additionally securing them with screws at 32 points, moving from the center.
The installation of the sheets is carried out staggered, filling the voids with sealant and not forgetting about the 5 mm gap at the walls.
The first row of parquet boards is glued using restrictive wedges. Optimal size gaps - 10 mm from the wall.
The adhesive mixture is re-applied to the plywood base and the ends of the parquet board, gluing them together and additionally securing them with nails.
To achieve maximum adhesion, the boards are pressed to the floor with maximum force, and excess glue is carefully removed with a dry rag.
Each subsequent row is shifted relative to the previous one by half the board.
Using a level, check the evenness of the laid surface.

After installation is completed, the floor is left for the period recommended by the manufacturer of the adhesive used in the process. Only after the coating has been thoroughly strengthened do they proceed to sanding it, treating it with oil or varnish and other manipulations at the final stage of installing the floor.

Laying parquet using the deck method

Installation method without plywood - features

It is not always necessary to glue parquet onto a screed using a layer of plywood. The boards can be attached directly to the concrete base. Naturally, it must be completely ready to carry out such work:

perfectly smooth;
clean;
dry;
no elevation changes.

The dies are attached using the same glue, but this time the stage of priming the base becomes mandatory. The planks are laid out (the first two rows are enough) in the order in which they will be mounted, after which the base is treated with glue using a notched trowel prepared in advance. The first board is fixed with a gap of 6-12 mm from the wall. Next, using a tamping block, secure the next one, pressing it tightly to the floor.

As soon as the first row of parquet boards is laid, the last block is trimmed, starting the next row. During the installation process, constantly use a level to control the evenness of the surface, making sure that no gaps form between the dies or rows. After finishing the work, the seams are treated with acrylic sealant and the floor is left for a period of two to five days (depending on the glue used) before sanding begins.

Installation of parquet boards, unlike installation of piece parquet, takes less time

Laying parquet - a method without plywood

Block parquet, just like boards, can be attached directly to a prepared concrete base without a plywood backing. In this case, you will be able to save time, money and effort, since you will need half as much glue and fasteners.

Why was the technology for laying parquet and boards developed? plywood sheets? Its roots go to Soviet times, when in most typical apartments the subfloor was built on wooden joists And wooden floors with bitumen backfill and hardboard on top.

Tens of years have passed since then and the foundation has been transformed to sand-cement screed with a layer of fixed plywood. With the advent of truly strong and reliable adhesive mixtures became possible installation parquet directly onto the screed without plywood.

Considering that the material is small in size and has an ideal geometry, the installation of block parquet is carried out without any particular difficulties and defects in the form of cracks and gaps. After finishing The block parquet floor is smooth and reliable. Attach the boards to the base using glue. Nails and plywood can be used to strengthen the joint, but this is not necessary. The principle of laying parquet is similar to the principle of installing parquet boards with glue.

At the final stage, after the glue has dried, the surface of the parquet is sanded manually or with a special machine (can be rented), the cracks are puttied, and sanded again. The finished surface is primed and coated with a layer of varnish or oil, depending on the owner’s choice. The varnish coating will protect the floor from moisture, mechanical damage, will add aesthetics to it and extend its service life.

Block parquet is laid with glue in the same way as parquet boards

The situation is somewhat different with solid boards. In terms of geometry and parameters, it is not as ideal as strips of block parquet, so installation on a screed without plywood is only possible with additional tightening and fixation with nails, and therefore the use of a plywood backing.

One way or another, regardless of the chosen method of fastening the parquet board or piece parquet, you need to remember that natural wood requires compliance with temperature and humidity conditions in the room. Neglecting these requirements will lead to a violation of its performance characteristics, and even the strongest glue together with nails will not save the situation.

The word "parquet" is French in origin and translated from "parque" means a floor made of small unpainted planks that can be laid different ways V geometric figures. When laying parquet flooring, it can stick to the base; sometimes a “floating” method is used. It is no secret to anyone that the entire installation procedure, its quality, and therefore the long-term operation of the floor covering will depend on the quality of the adhesive composition for parquet. Let's talk today about how to choose adhesive for parquet.

Requirements for parquet adhesive

To install parquet flooring in a room with high quality, you need to choose the right adhesive for installation. A good adhesive composition for parquet is a guarantee of long-term operation of the floor covering. It is important to take into account that low-quality, incorrectly selected, or even counterfeit parquet adhesives, as well as expired substances, which are usually sold at a 20-40% discount, will certainly show their worst properties, later, of course, but they will. And then you won’t be able to fix anything.

When purchasing parquet adhesive, you should pay attention Special attention on the requirements for the composition:

Parquet adhesive must be durable and capable of holding the coating in place firmly and for a long time, since the useful life of a solid board reaches one hundred years.
A good parquet adhesive should have some residual elasticity after curing, while still allowing the wood on your floor to expand and shrink when exposed to room temperature and moisture, which is completely natural for wood.
High-quality parquet adhesive, be it bostik parquet adhesive or artelit, should not shrink over time, which can cause squeaking when the parquet planks weaken when the glue sag underneath them.
Parquet adhesives for laying parquet flooring should not contain a lot of water in their composition, as is often the case when purchasing a cheap and low-quality composition, or a fake. Excess moisture when absorbed into parquet, it causes swelling and deformation of the coating, which subsequently also leads to squeaking. And if such a water-based parquet adhesive is used for exotic wood species that contain oils, the parquet flooring simply will not stick well.
Parquet adhesive must be safe and not contain solvents or other harmful substances. A sign of the presence of solvents is a pungent odor during parquet installation. Solvent-based formulations contain substances that, after use, for a long time will evaporate and poison the air in the room, even when you can no longer smell it.

Types of parquet adhesives

Today, there are 3 types of glue intended for laying parquet boards.

Dispersion glue

Dispersion adhesive is the most environmentally friendly pure material and is especially popular among European consumers. This mixture is based on water. This contributes to the fact that during the hardening process of the mixture, vapors are released that are not toxic and therefore do not pose any danger to human health and can be used in any residential premises. Water-based compositions are characterized by the absence of a pungent odor, which makes their application possible in residential areas.

The range of water-dispersed adhesive compositions is quite large, but they all differ, depending on the percentage of water in the composition. The higher the water content, the lower the price of the glue. Among the advantages of dispersed parquet adhesive Tarbikol Bostik is its fairly low cost compared to other types of glue. It is usually used for gluing moisture-resistant plywood under parquet.

Water-based adhesives are recommended for use when arranging oak parquet, because this type of wood is highly resistant to the harmful effects of moisture and is very durable. Water-dispersion adhesive is also well suited for laying piece parquet, which is small in size.

It should be remembered that wood undergoes deformation at the slightest contact with water, sometimes this even leads to rotting. Unlike oak, parquet flooring made from fruit varieties of wood (apple, cherry, pear), maple, ash is less durable in terms of “moisture resistance”; the boards can become deformed, especially if the thickness of the parquet floor is minimal and the dispersed adhesive has 36 % water in its composition. In such a situation, it is preferable to use a parquet adhesive from a different group. Dispersion adhesives are not suitable for laying such “capricious” species as beech and alder.

Solvent based adhesive

Solvent-based adhesives are the most commonly used adhesives for hardwood floors. Such substances do not contain water in their composition, so they are suitable for any type of wood. This group of mixtures differs from water-dispersion mixtures in their high adhesion strength.

Solvent-based adhesive can remain open for quite a long time - up to 15 minutes, which simplifies the work of laying parquet and allows you to correct parquet strips that have already been laid for some time due to their high fluidity. Complete hardening time usually reaches 5 days. Therefore, such products are recommended for use when laying floors made of wood types that are subject to swelling and other irreversible changes that occur under the influence of moisture.

When using solvent-based rubber parquet adhesives, remember that such substances are explosive and flammable. Therefore, this type of material is strictly prohibited from being used near such ignition sources. At installation work You should refrain from smoking in the room where they are produced.

Two-component reactive adhesive

Two-part or reactive adhesive is the strongest hardwood flooring adhesive available today. Hardening occurs as a result chemical reactions after adding a hardener to the mixture, because that is why the composition is called two-component. The glue does not contain water or solvents. The fully two-component adhesive cures in approximately 24 hours.

The hardening process of parquet adhesive occurs 2 times faster than when using organic solvent-based adhesive. The composition is 3 times stronger than conventional glue. Due to its versatility, such glue can be used on any substrate - wood, plywood, concrete.

Reactive adhesive can be used for gluing any parquet flooring, regardless of the type of wood and the size of the planks, even the most expensive artistic parquet. Uzin two-component reactive parquet adhesive is the best solution for solid wood flooring. It is recommended to lay boards that have already been varnished only with this type of parquet glue.

The only drawback of reactive glue is its rather high price, but it justifies itself with its excellent quality and for a long time operation. Also remember that when evaporating, the mixture will release harmful substances before final hardening. chemical substances. Therefore, you should only work with reactive adhesives wearing protective masks or respirators. The substance does not pose a health hazard after hardening.

Purpose of parquet adhesive

You already know that parquet adhesives come in water-dispersion, reactive and solvent-based types. However, when choosing a composition, you need to take into account the type, characteristics and dimensions of the material that you will glue - parquet made of oak, ash, fruit and exotic species, solid boards, the type of base for the coating and its properties. So, which adhesive is best for parquet?

Gluing plywood to a screed without fastening with screws

In this situation, it is imperative that the adhesive composition has the highest adhesion to wood and cement screed. In addition, it is required that the glue absorbs various stresses between the screed and the plywood, that is, the mixture must be highly elastic.

Gluing plywood to a screed using self-tapping screws

Unlike the previous situation, in this case the plywood is not simply glued to the base, but is also additionally secured with dowel screws, due to which the requirements for glue are somewhat reduced. Thanks to the self-tapping screws, changes in the geometry of the plywood will be almost neutralized, so you can use water-based Bostik parquet adhesive, which costs much less than its polyurethane counterparts.

Gluing uncoated piece parquet (ash, oak) to plywood

Piece parquet flooring made from a stable type of wood, for example oak or ash, with parquet flooring dimensions up to 420 millimeters in length and 70 millimeters in width, can be glued using water-based dispersion adhesive. The moisture contained in it is not able to be absorbed into the board small size stable rocks to such an extent that they change geometric shapes of this die. Keep in mind that dispersion adhesive that contains water will dry more slowly than polyurethane adhesive.

Gluing factory-coated parquet (ash, oak) to plywood

If you need to glue piece parquet that has already been coated, then it is better to use one-component or two-component polyurethane adhesive for Artelit parquet in order to avoid even the slightest possibility of warping, which will have disastrous consequences for a coated parquet floor - they will be visible on the finished coating defects.

Gluing any parquet, with bottom side varnished

In this situation, two points need to be taken into account. The glue must have maximum level resistance to vertical tearing. Before starting work, it is necessary to carry out a test for such a peel, because peeling along the varnish may occur, which is unacceptable.

Gluing uncoated piece parquet (fruit and exotic wood, maple, beech) to plywood

Some types of wood, for example, maple, beech, cherry, pear and almost all exotic species are considered unstable, that is, parquet flooring made from them will react sensitively to any changes in temperature and humidity conditions, and the wood will warp in this case. In order to avoid this situation, when gluing such parquet, you should use Bona parquet adhesive, which does not contain water.

Gluing glued solid wood and parquet boards to plywood

Parquet, which consists of several layers, usually consists of large-format boards with a locking system. Therefore, the parquet adhesive used when working with such flooring should not contain water. Otherwise otherwise long and wide boards will be subject to warping. The adhesive for layered parquet and parquet boards must necessarily be elastic, that is, such that it allows the parquet to be released if necessary, but at the same time there must be a force that tries to pull the parquet back to the plywood.

Gluing solid boards up to 120 mm wide to plywood

For gluing a narrow solid board, dispersive water-based glue will no longer help, since this composition will certainly over-moisten the wood, causing it to warp. The adhesive must be highly elastic and durable to reduce the tension between the plywood and the solid board that occurs during periods of fluctuations in air humidity. This is especially true in the spring, when heating season ends, and the humidity in the room rises.

Gluing solid boards wider than 120 millimeters to plywood

When laying a large-width solid board, what comes to the fore is not the elasticity of the adhesive, but its resistance to the effects of vertical tearing, because the stresses that arise between the wide-format solid board and the plywood will be much higher than in a situation with smaller according to the size of the boards. The most best properties One-component Ansercoll parquet adhesives based on high-quality synthetic resin have excellent performance in this regard.

Gluing coatings to a weak cement screed, except for solid boards, with a width of 120 millimeters or more

If there is a need for flooring wood covering directly onto the screed, which is not too strong, it is necessary that the parquet adhesive has the highest rates of adhesion to different surfaces. That is, the highest possible adhesion to the plane is required at the molecular level, which can completely prevent the possibility of a rupture in the adhesive composition.

Gluing coatings to a durable cement screed, except for solid boards, with a width of 120 millimeters or more

Compared to the previous situation, in this case we are talking about installing the parquet strip on a strong screed. The best, but also expensive, method of gluing is considered to be laying parquet flooring through a special layer - multimol. This elastic woven material is used to relieve tension between the parquet and the screed. Remember that the glue consumption will be 2 times higher, because first you need to glue the multimol, and then glue the parquet itself to the multimol. Alternative and more economical option- use of two-component parquet adhesive Adesiv, which has a high level of strength.

Gluing solid boards, with a width of 120 millimeters, to a durable cement screed

This situation occurs quite rarely in practice, but there is a way out of this situation. In such a situation, parquet adhesive must meet two requirements: greater elasticity, that is, the adhesive composition must be polyurethane, as well as the highest possible resistance to tearing off parquet strips in the vertical direction. The use of wide-format solid boards directly on a cement screed has its own advantages and disadvantages, so find out in each individual whether multimol will improve the characteristics of the solid boards or not.

Gluing industrial parquet (coating of thin and narrow lamellas)

Industrial type parquet flooring is fairly new and current solution, intended primarily for buildings with high traffic. This parquet flooring consists of narrow vertical slats. Numerous tests show good characteristics similar coating when gluing it with two-component parquet adhesive.

Thus, the choice of adhesive for parquet flooring depends on many criteria. If you decide to install parquet in your home, then remember that it must be of high quality, durable and elastic. In each specific situation It is worth choosing the appropriate composition - dispersed, two-component or solvent-based.

Many who want to lay parquet themselves often wonder what kind of base they should lay on.

The two most common methods are:

On a substrate / floating method (plywood is glued to the concrete base, then parquet flooring is laid on the plywood).
With glue (the parquet flooring is glued directly to the concrete base).
There is also a method of laying parquet using multimol(s) - when a special layer is laid between the concrete base and the parquet covering synthetic material– multimol(s), this method is not widely used, so it will not be touched upon by us.

Each method of laying parquet has its pros and cons.

Let's look at the nuances of laying parquet with glue directly to the concrete base:

When laying parquet with glue, we get a stable floor that does not knock or drum underfoot, and there is no risk of squeaks occurring over time.
Such a floor can be loaded with massive objects.
Minimal sound reflection - noise and sounds are dampened.
It is possible to install a parquet board in a continuous field throughout the entire apartment without thresholds and transitions only by gluing it to the base. Or perhaps install in doorways compensation cork thresholds that do not protrude in height. With this approach, it becomes possible to create a flat floor surface without the use of protruding overhead thresholds.

Photo of laying block parquet on concrete

The nuances of parquet flooring laid in a floating manner (on plywood / on a substrate):

With this method of installation, the parquet floor cannot be loaded with massive pieces of furniture, since the floor must remain floating (i.e., move and breathe).
In a room with a floating floor, sound bounces off the floor surface and back into the room.

When laying the parquet floor on the substrate, the rooms are strictly cut off at the doorways, and an overhead threshold is installed at the joints of the floor coverings, so as not to squeeze the parquet to the base. Under no circumstances should you glue the threshold at the junction with the parquet board!

Obviously, laying parquet flooring on a concrete base is more winning option than laying on plywood. Laying parquet on a concrete base is best handled by

Regarding parquet, you can often hear the following very practical advice: if you buy it, then buy it of the highest quality possible; otherwise it will be very disappointing if such an expensive flooring will have to change soon. The choice of adhesive for parquet should be carried out using the same approach. After all, all the components of a parquet floor - parquet, glue and protective covering- in fact, they are links of one chain: if one of them turns out to be unreliable, the entire structure will suffer.

In this article we will talk about the types adhesive compositions for laying parquet, as well as the properties they should have.

Requirements

So, let's start with a short lecture on what qualities a person should have good glue for parquet. There are not so few of them:

Durability: high-quality parquet with a fairly thick face layer when proper care capable of serving for an extremely long time - more than a hundred years. Therefore, the glue should have the same durability.

Plasticity: after hardening, parquet adhesive should retain some mobility, which will allow wooden dies to change in size without stress with changes in temperature and humidity.

The ability to provide strong adhesion to the base: parquet adhesive should perform its main function especially well. Firstly, parquet, like any other flooring, is constantly exposed to stress when people walk; and secondly, this material is also periodically sanded, which is also a good test of the glue’s strength.

No shrinkage: if the parquet is glued with an adhesive that shrinks over time, the floor will soon begin to creak.

The amount of water in the composition corresponds to the type of wood: as you know, most types of wood are not friendly with water. So water-based adhesive can only be used for installing parquet flooring that consists entirely of moisture-resistant species, such as oak. Any other one will swell upon contact with water and begin to creak, and possibly rot. In addition, water-based parquet adhesives are not able to provide sufficient adhesion for planks made from oil-rich tropical trees.

Environmental friendliness.

Today it is extremely important to remember that modern construction and Decoration Materials may release toxic volatile substances into the air. There are many known cases of poisoning caused by paint fumes, wallpaper glue and even linoleum. Therefore, for gluing parquet, whenever possible, you should use compositions in which harmful substances are absent altogether or are present in minimal quantities.

Types of parquet glue

Also, to answer the question of which adhesive to choose for parquet, you need to know the classification of these products according to chemical composition, more precisely by the type of base. First of all, they are divided into two large groups:

One-component: these adhesives are already sold in finished form, so you can use them immediately, which is very convenient.

Two-component (reactive): such glue must be prepared before use, since the hardener for it is packaged separately from the main composition. This makes life a little more difficult for the installer, but two-component adhesives provide a much stronger connection than their one-component counterparts, which plays a big role when installing varnished parquet or heavy solid boards. In addition, the compositions of this type prevent damage to wood by mold and mildew, which is especially important for parquet made of beech, ash and fruit trees.

Now let's look at each of the varieties in more detail.

One-component adhesives

Ready-to-use compositions come in the following types: water-dispersed and compositions prepared on the basis of solvents, silane and polyurethane.

Water-dispersed

This is the safest adhesive for parquet, since the fumes it produces do not contain any toxic components. However, due to the presence of water in the composition, it is only suitable for moisture-resistant wood (oak, larch) or for parquet, the dies of which are very small in size.

Coverings made of beech, alder, ash, maple and fruit tree wood should not be glued with a similar composition, since these materials are not only not moisture resistant, but are generally very demanding in terms of humidity conditions.

Exotic species, which are characterized by a pronounced ability to repel water, for example, teak, balau, merbau, will not swell upon contact with this glue, but due to the presence large quantity oils in their structure, the adhesion force may be extremely low - it is recommended to first check the magnitude of the pull-out force.

When purchasing glue for water-dispersion basis you should pay attention to exactly how much water is in it (its share is indicated as a percentage). The more “watery” the composition turns out to be, the cheaper it will cost, but its adhesive properties will also be worse.

Solvent based adhesives

Compositions of this type can be used for gluing any wood, only the boards should not be too large, otherwise the strength of the connection will be insufficient. Another disadvantage is the evaporation of the solvent, which is not only harmful to health, but also dangerous from the point of view of the possibility of fire.

Therefore, it is advisable to work in a respirator with solvent protection, and smoking and use open fire must be excluded. Harmful volatile substances are released by this glue for quite a long time - up to 45 days. During this time, it is advisable to exclude people, especially children, from staying indoors.

The curing time of solvent-based adhesives is relatively long - about 5 days. During this period, it is possible to correct the position of the boards.

Polyurethane glue

This parquet adhesive should be applied to a screed, which can be concrete, cement or anhydrite. The composition is characterized by extremely high tenacity, which is why it is usually used when constructing floors subject to significant loads.

Also, polyurethane-based adhesive is indispensable when installing heated floors (warm floor systems). Hardening time is about 24 hours.

Silane based adhesive

This composition appeared quite recently and today represents the most advanced development. This, in fact, is the answer to the question of which adhesive is best for parquet, and here’s why:

silane adhesive does not contain solvent or any other volatile substances harmful substances, therefore it is absolutely safe (the composition hardens as a result of interaction with moisture contained in the air);
due to the absence of water in the composition, it can be used when working with any wood;
demonstrates the highest adhesion, and on any basis, including screed;
after hardening it retains sufficient ductility;
can be used in rooms with high humidity and in “warm floor” systems (tolerates temperature fluctuations well);
can be easily removed from any surface without leaving a stain;
dries very quickly;
has sound-absorbing ability.

Silane glue has only one drawback. It's easy to guess that we're talking about about the high cost.

The zaWood company sells Russian silane-based parquet adhesive. For its production, only European binders are used, so the quality of the glue remains at high level, at a very low price for this segment.

Two-component adhesives

Compositions of this type are also characterized by some diversity. Here's what they are like:

Polyurethane

This glue is very expensive, but it has a number of advantages:

retains high ductility after hardening;
is environmentally friendly;
Suitable for any type of wood.

Epoxy-polyurethane

A more affordable composition, but less plastic. Another drawback is the presence of harmful fumes with a pungent odor, which is due to the presence of epoxy resin in the composition.

About the manufacturers

The buyer does not have the opportunity to check the quality of the glue, especially in the long term. In such a situation, the best evidence of reliability is the name of the manufacturing company, so it is highly advisable to know several brands that enjoy high consumer confidence.

Bostik parquet adhesives are very well known and popular. This brand produces a whole range of formulations intended for various tasks. Polyvinyl acetate mixture, alcohol, polyurethane and other substances are used as a base. At the same time, all products are of high quality and, if possible, environmentally friendly, and the manufacturer sets prices that are not exorbitant.

The most popular varieties are:

Bostik Tarbicol KPA: one-component alcohol-based composition. It is quite durable, which makes it suitable for installing solid boards, and tolerates temperature changes well, so it can be used for gluing parquet onto a heated base.
Bostik Tarbicol PU 1 K: one-component composition based on polyurethane. Demonstrates high strength and is frost-resistant. There are no solvents in the composition, so this glue does not emit harmful fumes and does not have a sharp unpleasant odor.
Bostik Parcol PU 56: two-component polyurethane-based adhesive. It has increased adhesion and provides the connection with ultra-high strength, so it can be used for gluing parquet to bases made of any metal alloy, concrete or cement.
Bostik Elastic: glue on polymer based, also environmentally friendly. Designed to work with material up to 23 mm thick and any base. Thanks to its waterproofness, it can simultaneously perform the function of waterproofing.

Another worthy manufacturer of parquet adhesive is the Bona Bond company. Its chemists managed to develop a water-dispersion composition in which the water content is greatly reduced.

Polyurethane adhesive for Bona parquet, which is available in both one-component and two-component versions, is also in good demand.

How is parquet glued?

A truly high-quality installation of parquet can only be done on a completely dry screed. Therefore, if it was completed recently, it is necessary to postpone the continuation of work for a month - usually this time is enough for complete drying.

First, steam and waterproofing are laid on top of the screed. As the latter, you can use plywood, which is glued using the same parquet glue. For reliability, it is additionally screwed on with screws. Before this operation, the screed will need to be primed. Another option is to use it as waterproofing bitumen mastic. In this case, there is no need to prime the screed.
