Laying a parquet board on a substrate or on glue?! Laying parquet boards: with glue or without? What glue to glue the parquet

One of the pleasant and visible stages of the repair of residential premises is the installation of parquet floors - a well-chosen adhesive for parquet will allow you to independently perform this work with proper quality, quickly and accurately.

Advantages of parquet floors

The wall decoration and ceiling work are completed, and the installation of plumbing communications is a thing of the past - it's time to start arranging the floors. Natural parquet has been and remains the most popular flooring in residential areas due to the following qualities:

Laying parquet floors - the importance of pre-treatment

A prerequisite for a durable and beautiful parquet floor is a flat base. best method for this, it is rightly considered by means of cementitious self-levelling compounds. V small rooms it is permissible to perform a screed with a cement-sand mortar “along the beacons”, for rooms with dimensions from 4 meters to short wall and more professional screed is needed.

After the cement base has hardened, check its horizontalness. Regardless of what is written in the accompanying documentation for the parquet, the height difference of the finished screed should not exceed 2 millimeters per running meter of the floor in any direction.

For such a check, a quality level of sufficient length and high precision. If the height difference is more than 2 millimeters, the base must be redone (a little more “raise” with an additional layer of fill or trim the protruding sections and fill them again). No two-component adhesive for parquet, polyurethane and others can compensate for the flaws of the base.

It is equally important to determine the moisture content of already hardened cement - laying parquet elements must be carried out on a completely dry floor. Of course, you can perform such measurements with hygrometers, but these devices cannot be called common, and it will be too expensive for the budget to purchase them for episodic work with parquet. You will have to get by with a "folk remedy" for determining the moisture content of the floor, especially since it is quite accurate.

On several sections of the screed at different ends of the room (especially near windows, radiators and pipeline communications), pieces of ordinary dense and transparent cellophane are glued, preferably at least 1x1 meter. If after a day the inside of the cellophane does not fog up, you can proceed with the styling activities. If there is condensed moisture inside the film, the floor base needs additional drying. If necessary, you can use convectors for air circulation. In any case, the cement screed before the “parquet laying” stage must be even (2 mm per meter!) And dry.

Of course, parquet cannot be laid on concrete, cement or stone. Must be fixed to the floor moisture resistant plywood, leaving gaps of 10-15 mm from the walls and securing with self-tapping screws (at least 10 per square meter). Plywood with moisture-resistant qualities prevents dampness from the inside of parquet tiles and additionally levels the floor. The heads of the self-tapping screws must be completely recessed into the plywood, after which it must be treated with a primer. The primer layer increases adhesion (sticking) adhesive compositions, binds the remnants of dust and sand and closes cracks with irregularities in the plywood itself.

Parquet glue - the main varieties

The labor-intensive preparation is over, and it's time to choose which parquet adhesive we need. Is it possible to get by with a budget water-dispersed composition, or will a significantly expensive reactive adhesive be required? The main varieties are named, it remains to describe their features in the case of "parquet installation":

Water-dispersion adhesives. The cheapest, easiest to use and (by the way!) are environmentally friendly. Unfortunately, the presence of moisture is very dangerous for the durability of parquet, especially if it is made of maple, ash, beech and any kind of fruit trees. The lower the concentration of water in dispersion adhesives, the higher their versatility.

For instance, Kiilto Standard(Finland) contains 36% H 2 O, it is better to use it for gluing oak parquet, massive board or plywood. Known composition BONA B-720(Sweden) with 22% water is suitable for any parquet with a plank thickness of 10 millimeters or more. For thin tiles made of ash, beech, pear, maple, an even lower concentration of moisture in the adhesive is required . All water-dispersion adhesives take a very long time to dry - from five days to a week or even longer, so the planning of working with them is very important..

Adhesives on solvents or one-component. Suitable for any bases and any parquet boards, the drying time is also measured in days. One-component polyurethane adhesive for parquet is convenient in terms of the ability to touch up the parquet pattern after laying. The composition remains fluid (in the open state of the container and after application) for up to 20 minutes, that is, it is possible to correct entire rows of tiles.

Unfortunately, all one-component formulations are flammable, and many have a very pungent odor and toxicity. They should work in well-ventilated areas and in no case should smoke during work and should not use fire at all in the room being repaired. The laid floor can be sanded after 3 days, complete drying is achieved on the fifth day. The most popular one-component adhesives for parquet STAUF WFR-4, MK-97 and UZIN MK-73.

A two-component adhesive composition for working with a parquet board is a fairly thick emulsion, to which an exact portion of the powder is added and thoroughly mixed before application. They combine all the advantages of water-dispersion and soluble adhesives - they dry quickly, fit any type and size of parquet, are environmentally safe and non-toxic. To the question: “How to glue the parquet securely and beautifully?”, The most natural answer would be a recommendation for a two-component adhesive.

The only drawbacks of two-component adhesives (they are also called reactive at the expense high speed curing) is a high price and difficulty when working in conditions low temperatures. If, for some reason, parquet has to be laid in frost, it is reasonable to give preference to a one-component adhesive. Of the brands of reactive compounds, the most popular BONA H-790, STAUF ZK-PU, UZIN MK 92S.

It is no secret that the durability of any floor covering largely depends on the quality of its installation and, in particular, on the choice of adhesive composition. Glue for parquet board helps to make the coating more durable and reliable. The parquet will not emit extraneous noise due to a loose fit to the base, and its service life will increase significantly. Laying parquet boards on glue is technologically simple, but before choosing it, you need to decide on the materials from which they are made. This is very important because not all adhesives are universal and may not be suitable for certain types of wood.

Which glue is best?

There are only a few main types of adhesive compositions intended for laying parquet boards:

dispersion, made on water based;
synthetic, which contains solvents;
two-component, made of polyurethane with the addition of special hardeners;
one-component based on silane-modified polymers.

It is worth noting that when using glue, it is not necessary to carefully level the base, since this function is performed by the adhesive mass itself, closing up small recesses, cracks and chips. But if the subfloor has too large irregularities, then it is recommended to pre-make cement screed.

Water-dispersion adhesive

The main feature of water-based glue is the absence of a pungent odor. It is completely harmless, therefore it is successfully used in residential premises. Water-dispersion adhesive for parquet boards is quite popular among European consumers, but it has one significant drawback - certain types of wood are poorly tolerated by moisture, such as:

Cherry;
pear;
Apple tree.

Water-dispersion adhesive compositions are used for parquet boards made of oak, larch, and some exotic types of wood. Moreover, the lamellas should consist of three or more layers. Moisture-resistant rocks can deform under the action of dispersion adhesive and, as a result, change the shape of the floor covering.

Synthetic glue

For parquet boards that are sensitive to moisture, adhesives based on rubber or synthetic resins are used. They contain a solvent, so when working on laying parquet boards, safety measures and precautions must be observed. In particular, it is forbidden to use synthetic glue near open flames or hot objects, it is also forbidden to light matches, lighters, and also smoke in the room where work is being carried out. It is allowed to store synthetic glue in tightly sealed containers in well-ventilated areas.

Today, solvent-based adhesive for parquet boards is the most popular. A high flow rate allows you to adjust the position of the lamellas even after they are laid, and in the open state the adhesive composition can be up to 15 minutes without setting. Complete curing of the adhesive occurs after five days, but sanding flooring you can start a little earlier.

Two-component adhesive

Thanks to polyurethane and special hardeners, the two-component adhesive sets and cures much faster than synthetic or water-dispersion adhesives. Its advantages include the following:

the ability to use on any surface;
high bonding strength, almost three times higher than other types of glue;
the admissibility of the grinding process in a day, due to the rapid setting.

Another name for a two-component adhesive is reactive. He received it due to the implementation of the bonding process by a chemical reaction. It is necessary to work with such adhesive compositions if funds are available. personal protection because they contain harmful substances. But after hardening, the glue becomes absolutely safe for health.

A two-component adhesive mixture is used for parquet boards of any size, made from precious woods, or in the case of laying lamellas directly on a cement screed. The composition is universal, easy to apply with a spatula, it can be used in "warm floor" systems.

One-component adhesive

A universal adhesive mixture based on a silane-modified polymer can be used for any type of parquet board, including those made from wood species that are slightly resistant to moisture. The slats can be sanded or varnished after 48 hours. Single component adhesive.

Yes, frankly, parquet adhesives on the market enough to get completely confused if you do not understand this. Therefore, we will try to give you clear recommendations so that neither parquet floors nor illiterate sellers deceive you. How many times do we hear the same questions when entering into a dialogue with a client:

What glue to buy for plywood?
- how to glue a massive board?
- on what to lay a piece parquet from an ash-tree?
- and many others...

Groups of parquet adhesives, according to their purpose

Dispersion adhesives without solvents 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 on a concrete base, also when diluted 1:1 with water as a primer for application to a cement screed. As a result, this group of adhesives has a very limited application. Grinding not earlier than in 7 days.

Solvent Adhesives include rubber and synthetic resins. They can be glued to multi-layer lacquered parquet boards, piece parquet made of oak, ash, beech or maple up to 22 mm 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 afraid of frost.

Two-component polyurethane or epoxy-polyurethane adhesives are the most versatile, 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 almost without 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 strong, work time ready mixture 2 hours. Relatively inexpensive, easier to work with when laying, but more toxic to parquet floorers. Some types of this parquet adhesive are produced without solvent. Practically without restrictions, they are used in parquet work and for laying plywood with and without self-tapping 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 when residual moisture indoors, the adhesive does not adhere well. Contains neither water nor solvent. Sanding after 4-7 days.

Parquet adhesives based on MS polymers or silane adhesives are the most flexible of the above. They are used for treated and untreated types of parquet, have increased sound insulation, and are suitable for underfloor heating. They have limitations in the use of the width of the board. Good adhesion for exotic woods. Cures with atmospheric moisture. Sanding after 3 days.

Hybrid Adhesives are made on the basis of silane-modified polyurethane, are elastic and strong enough. They can be used almost without restrictions for any kind of laying of parquet or plywood, do not contain any water or solvent. Cures upon contact with atmospheric moisture, fully cured in 3-4 days.

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

The method of laying parquet on a concrete screed has its own characteristics and differs significantly from laying on plywood or OSB. The production technology of works consists of several stages, the high-quality implementation of each of them is of great importance.

Important. Remember that the slightest violation building codes and rules, at best, will cause unpleasant squeaks while walking, and at worst, a complete delamination of the coating will occur. Troubleshooting is a complex process that requires a lot of time and money. It is much more profitable to strictly follow the recommendations of manufacturers and not save on materials than to eliminate the consequences of not quality styling.

Regardless of the installation method block parquet for all adhesives there are General requirements.

Minimum shrinkage. The composition in the liquid state should not drastically reduce its thickness after drying. This setting depends on several factors: chemical composition, operational indicators of the base and the correctness of the preparation of the solution.
Elasticity. During use, the parquet changes its linear dimensions. There are two reasons for this phenomenon. The first is thermal expansion. During the heating/cooling of the lamellas, they increase/decrease the parameters, and if the floors are heated (which is not recommended for piece parquet), then the difference in length can be significant. The second - the tree has hygroscopicity, as a result of which relative humidity can fluctuate within significant limits. Humidity fluctuations simultaneously change the dimensions of the lamellas. Due to the elasticity, the adhesive must compensate for all changes, otherwise, after a short time, the adhesion of materials will deteriorate sharply. As a result, squeaks while walking or peeling of some sections of the floor covering.
Long service life. Floors made of piece natural parquet are one of the most expensive coatings. They are used only in prestigious premises, and not all of our compatriots are affordable at a cost. In addition, the price of laying parquet floors is much higher than other types of flooring.
Peeling of lamellas is a big problem, to eliminate it requires a complete dismantling and re-laying of the flooring. It is impossible to dismantle a parquet floor without mechanical damage to a certain number of lamellas. It is impossible to buy new ones with exactly the same characteristics, each batch of goods and each manufacturer has its own characteristics. color shades and texture. And if several years have passed between the first laying and repair, then it is even theoretically impossible to find identical materials. There is only one way out - to buy new parquet for the entire area. Repair will cost several times more than the first installation of parquet.
Minimum amount of water. Natural parquet, like all lumber, is very hygroscopic. Prolonged direct contact with water can cause warping, such a floor has to be completely redone.
Ecological safety, absence of unpleasant smells. Important Points. Unfortunately, there are no high-quality natural-based adhesives. The better the performance of the material, the more various chemical compounds it contains. There is only one consolation - the amount of harmful emissions is tightly controlled by government organizations. And the parquet coating is so dense that it almost does not let air into the living space.

Knowing the general requirements, you can more carefully approach the choice of a specific brand of glue, taking into account the maximum number of existing features. But the strength of parquet on a concrete screed depends not only on it, we will talk about other factors a little lower. Optimal choice glue is important, but not the only condition for the durability of the parquet floor. What adhesives can be found today in the implementation?

Overview of adhesives

Professionals distinguish several groups of compositions, each of them has its own performance characteristics.

Dispersive

The safest adhesive, does not contain aggressive chemical compounds, odorless. In connection with large quantity water, it is recommended for laying parquet made of moisture-resistant wood species (larch, oak). Not recommended for parquet made of beech, maple, ash and other types of wood that are unstable to high humidity. Another disadvantage of water-based glue is the relatively long drying period. In terms of adhesion, it is inferior to more modern compositions.

Synthetic

Synthetic resins or rubber are used as adhesives. Recommended for laying floor coverings natural wood, hardening time ≈15 minutes. Artificial resins do not have high adhesion rates; in connection with such features, increased requirements are imposed on the primer and screed.

Two-component

The most expensive and most durable compounds, universal application, can be used for any basis. Two components must be mixed before use: hardener and adhesive. In liquid form, harmful chemical compounds are released, you need to work in personal respiratory protection equipment. Epoxy two-component adhesive, after hardening, turns into a solid inelastic material, which somewhat narrows its scope.

Polymeric

In terms of cost and effectiveness, it occupies an average position. The adhesive hardens under the influence of moisture contained in the air. It is made on the basis of MS-polymers (silanes), has the effect of sound insulation. Disadvantages - sharp bad smell and a long freezing period.

One-component polyurethane

After hardening, elasticity remains, it can be used for both parquet and plywood. Does not pass capillary moisture, prevents swelling of lamellas. Characterized high adhesion with most building materials, dries quickly, can be used with any type of wood, regardless of its reaction to high humidity.

When determining the optimal adhesive, it is necessary to take into account not only the characteristics of the base and parquet, but also the expected load on the floors.

For all cases, there is one important condition - before using the adhesive, the concrete base must be primed. The quality of the primer has a great influence on the bonding strength of the parquet. For each adhesive composition, you need to select a certain type of primer. This nuance must be taken into account when choosing an adhesive; to facilitate the decision, you should familiarize yourself with the existing primers.

Primers for glue

Primers correct the process of absorption of glue by the base, bind dust, and somewhat strengthen the surface. Without them, one cannot hope for a strong connection between the parquet and the base. Universal advice - buy a primer at the same time as glue, their compositions should be as identical as possible. Polyurethane adhesives require polyurethane primers, dispersion dispersions, etc.

In addition to these important functions, primers on a concrete base protect the coating from rising capillary moisture. high humidity negatively affects the adhesion performance of all adhesives. It is possible to apply primers on concrete bases only after checking their moisture content. At indications ≤ 5%, only epoxy primers should be used, at humidity ≤ 1.5%, polyurethane primers are allowed. If humidity concrete screed> 5%, then the room must be dried before priming.

Types of glue for parquet on concrete screed

We will list the most common brands of parquet adhesive, these compounds have positive reviews professionals.

Has high rates of adhesion with all types of wood. During work it is necessary to use means of protection of respiratory organs.

It should be borne in mind that adhesives for parquet on cement screed are much more expensive than for other floor coverings. This is due to the high requirements for reliability and durability.

Wood is a living material that changes its characteristics depending on humidity and temperature, depending on the fluctuations of these parameters, not only its dimensions, but also other physical characteristics change quite significantly. Modern solutions take this feature into account and guarantee high and stable adhesion rates in any operating conditions.

How to use parquet adhesive

We have already mentioned that not a single, even the most high-quality and expensive, parquet adhesive will provide required degree adhesion of the floor covering with a concrete base, if the rules of use are grossly violated. How to install parquet to guarantee a long life of the parquet floor?

Step 1. Calculate the size of the room, buy a suitable adhesive, taking into account the consumption rate per unit area.

Practical advice. The norms indicated by the manufacturer on the packaging do not correspond to practical consumption. The thing is, they are perfect. flat surface and the same thickness of application of the material. In practice, such conditions do not exist, always buy glue with a small margin. This is much more profitable than interrupting the laying of parquet due to lack of material.

Step 2 Check the condition of the concrete screed.

Small gaps can be left unsealed, and height differences of more than two millimeters per linear meter will have to be eliminated. The easiest way to make a self-leveling floor, it has high strength and allows you to get a flat surface. If this is not possible for some reason, then the concrete base can be leveled with a cement-sand screed.

Important. The strength of the parquet flooring is directly related to the strength of the base. If the screed crumbles, then no glue will help. During the preparation of the mortar, increase the amount of cement by about 15–20% of the usual rate.

If possible, it is recommended to sand the base surface with special grinders before laying the parquet. They will not only level the floor, but also remove milk from the concrete, thereby significantly increasing the strength of the surface of the coating. This is very important for high-quality laying of piece parquet.

Step 3 Clean the room thoroughly with a vacuum cleaner. On the surface of the concrete there should not be not only a large construction debris but also sand and dust. The cleaner the base, the stronger the parquet will hold.

Step 4 Check humidity readings concrete base. This can be done using a special device, take measurements in several places, always in the corners of the room, here the humidity always has increased values.

If there is no device, then do it by eye: after pouring the mass, it should harden for at least 14 days, the last 2-3 days of the room should be constantly ventilated. Depending on the brand of adhesive, work can be started at relative humidity values on the base surface of less than 5%, some compositions can be used at lower humidity.

Step 5 Make a preliminary layout of the parquet, if desired, control lines can be applied to the base, with their help it is easier to check the correct laying.

Practical advice. If you plan to lay herringbone parquet, then immediately prepare all the segments. Glue, depending on the brand, cannot be weathered for more than 30 minutes, and for some formulations, the time is reduced to 10 minutes. You won't have time to trim the lamellas.

Step 6 Prime the base. The type of primer depends on the type of adhesive, be sure to consider this requirement when purchasing materials.

The primer should be evenly distributed over the entire area, use a roller. In hard-to-reach places, you can work with brushes.

Make sure there are no gaps. All professionals strongly recommend covering the base with at least two coats of primer, especially if the solution is quickly absorbed. During the application of the second layer, the movements of the roller should be perpendicular to the first, this will eliminate the allowances. Give the primer time to dry completely.

Step 7 Prepare the parquet adhesive according to the manufacturer's instructions. A single portion of glue should correspond to labor productivity. Please note that adhesives must not be diluted once the curing process has begun. All proportions should be carefully observed. Glue should be mixed electric drill with a whisk, cartridge speed is medium.

Too high speeds cause air bubbles to form in the adhesive, which Negative influence on the adhesion of materials. If you are preparing a two-component adhesive, then you need to stir with special care, the hardener should be evenly distributed throughout the volume.

Step 8 Using a comb trowel, apply adhesive to a section of the floor, the size of the area depends on your professionalism.

Take the lamellas out of the packaging one by one and lay them on the glue. At the same time, do not forget to leave a gap between the flooring and the walls, the gap width is 1–1.5 cm. Press the slats with your hands, make sure that they lie strictly horizontally. You should check the correctness of the installation using a level or a rule, if you have enough experience in performing such work, then control can be done visually. But we do not advise beginners to do this, the risks of mistakes are high.

Practical advice. Professional builders increase the bonding strength of parquet in a simple way and completely eliminate the risk of squeaks while walking.

It is done like this. Three or four slats are folded in an even stack and lean against the floor from the side of the spikes with smeared glue. Due to this, a little glue remains on the spikes, they enter the grooves and significantly increase the stability of the coating. Such actions do not take much time, and the positive effect is noticeable. There is no need to be afraid that glue will appear on the surface of the parquet, a small amount of it will always hide in the grooves.

To facilitate the work, you can make the simplest device for controlling the area of \u200b\u200bglue application. Take a piece of rope, its length should be equal to the width of 3-4 rows of parquet. Tie a pencil or marker to one end, any smooth object to the other. Rest the object against the edge of the laid parquet, pull the rope and slowly move it along the lamellas. A line should be drawn on the base, it will indicate how wide to spread the glue.

Laying parquet is carried out in an uncomfortable position, wear soft knee pads, this will facilitate the work. It is advisable to press the laid lamellas with some kind of load until completely dry. You can use packs of unused parquet.

adhesive for parquet

Video - How to quickly lay parquet

Depending on the composition of the product, water-dispersed, solvent-based and two-component products are distinguished. Each is used with certain building materials and provides quality coating in various conditions.

Dispersion adhesive

The substance is made on the basis of an aqueous dispersion of PVA or acrylic, to which synthetic resins are added. The mixture does not contain solvents and dangerous volatile elements, so it is environmentally friendly and is especially popular among consumers in European countries.

The tool is intended for fixing waterproof plywood (substrate) to the base, as well as for fixing moisture-resistant wood planks. Only oak and larch have such properties. The solution holds small piece elements well.

The quality of a water-based adhesive for parquet depends on the percentage of moisture in its composition than more value the cheaper the mixture.

Solvent adhesive

Such products contain a very small percentage of water and are used to fix plates from any tree. They are used in cases where water-dispersed mixtures are contraindicated, for fixing planks made of wood that is afraid of moisture. Substances on solvents from different manufacturers practically do not differ in quality and cost approximately the same.

The solidification process is accompanied by the evaporation of volatile elements that are harmful to the human body. After complete hardening, the release of toxins stops. The mixture does not set for more than 15 minutes, which is convenient for installation work. During this time, you can correct the position of the slats. Maximum strength occurs 5 days after laying.

Solvent-based fluids are explosive and flammable and must be handled with care. It is forbidden to work near open flames, as well as to smoke in the room where the flooring is being installed. The room must be constantly ventilated.

There are two types of solvent-based adhesives - oil-based (rubber) and alcohol-based. The first type includes liquids that can be diluted with acetone, white spirit, solvent, etc. The second type is made on an alcohol basis.

Solutions Aned A1 and Anzerkol 5-10-15-20 are universal adhesives for oil-based parquet, distinguished by strength and elasticity, as well as reasonable price. They retain their characteristics well in the cold. If the temperature and humidity in the room reached the maximum permissible values, very small gaps formed between the floorboards - up to 0.8 mm. The product can be applied without prior priming of the substrate.

The work is carried out using a significant amount of solvent with very bad smell. To protect against toxic fumes, the installation of the flooring is carried out in respirators. After the mixture dries, substances harmful to humans cease to be released.

There are some restrictions on the applicability of this tool. If the floor is heated, the mortar layer evaporates quickly, and after 5 years the floorboards will wobble. With strong heating of the surface, the substance may completely disappear.

Rubber adhesive for parquet Artelit RB-112 is produced by the Polish company Selena. Its main purpose is gluing finish coat and plywood, but he has proven himself well when working with any materials. It has excellent initial tack and excellent adhesive properties.

Compared to other similar products, it has a significant advantage - it has successfully passed the toxicity test in Ukraine. Manufacturers claim that it is not necessary to prime the base, however, for reliability, the substrate is impregnated special tool Artelit WB-222 or Artelit SB-212.

Alcohol-based adhesives are designed for mounting strips of all types of wood on a substrate that absorbs moisture. They contain a minimum amount of water. The product hardens after 72 hours, the flooring can be sanded after a week. After drying, the solution layer shrinks. The smell of an alcohol solvent is not much weaker than an oil solvent, but less annoying. It is believed that this is the only tool that can securely fix even a massive board.

The disadvantage is high price, because of which the substance is used quite rarely. The quality is strongly influenced by the shelf life of the product. If the product is more than a year old, do not buy it. Of the alcohol substances, the most reliable is Utsin MK-73.

Polyurethane adhesives

There are two large groups of polyurethane products that consumers are willing to buy - one-component and two-component.

One-component are designed to work with all types of piece and mosaic parquet of any size. Hardening occurs as a result of the reaction of the contents with moisture in the air. Often used for assembly finished coating factory-made, because mixtures do not destroy the protective and decorative layer.

After drying, they retain their elastic properties and do not shrink. They are used when installing flooring on a concrete floor. Among the shortcomings, a long hardening period can be noted - up to 4 days. Usually, the substrate is not primed before working with such a substance.

Of the one-component adhesives for parquet, Artelit HB-820 is popular, it has quite low price. back side low cost is expressed in extra costs time during installation work. The substance has a relatively low elasticity, low stickiness, and a weak initial setting. For example, after applying the adhesive, the plate should be moved a little through the solution, and then pressed firmly.

For consumers who do not know which adhesive to choose for parquet, we suggest paying attention to universal solution Tena Bond 141M. There are practically no restrictions on the use of this substance. It can fix plywood and floorboards to concrete, metal with any coating, synthetic materials. It is recommended to fasten wide floorboards (up to 130 mm) with this tool. The price of the product is not much higher than for Artelit HB-820, and the consumption does not exceed 1 kg per m 2.

For critical objects it is recommended to use Kilto Flex Silan polyurethane adhesive for parquet. It securely fixes even oiled and varnished items. large sizes. It is used for tacking a plywood base intended for laying solid boards with a width of more than 130 mm. The product expands well and does not crack even when the size of the coating is increased beyond the norm, for example, after a strong wetting of the wood. After some time, he returns to his size.

The disadvantages include the high cost of the product, as well as the release of toxic fumes during solidification. After about 24 hours, the mixture becomes safe for humans.

Two-component products are considered the best adhesives for parquet. They are sold in buckets. There is a base in the container, and a powder of a certain composition in the lid. To obtain a solution, the dry component is poured into the emulsion and thoroughly mixed, after which the chemical reaction of solidification begins. The mixture dries completely in a day.

The substance is stronger than other mixtures at times. It can be used for fixing materials on any base - wood, concrete, metal. The strength of the connection is not affected by the type of wood and the size of the sample.

Clay Uzin MK 92S is considered the most reliable and durable in the world, as evidenced by many years of operating experience. It quickly bonds any size board to a variety of substrates. During installation, it is recommended to use another solution with it, which hardens more slowly. This is due to the fact that with a long production of the edge trimmed dies, the product may harden, and the installation of the parquet near the walls will be of poor quality. The disadvantages of the tool include toxicity.

Two-component adhesive for parquet Uzin MK 92S is made from two ingredients supplied in the kit, one of which is very toxic. If the substance comes into contact with the skin, it causes severe pain, so protective gloves are sold with the product. Traces of a chemical burn on the affected skin disappear after three weeks. The mixture remains dangerous throughout the installation process, but then it loses its aggressiveness. When they talk about the environmental friendliness of Uzin MK 92S, they mean its state after hardening.

In the latest development, Uzin MK 92+ took into account the wishes of consumers and increased the hardening time, which makes it possible to obtain beautiful coverage under high temperature conditions.

Requirements for parquet adhesives

For laying flooring elements, buy mortars with the following properties:

Adhesive for parquet must securely fix the coating for a long time, because. wooden surface does not deteriorate for more than 50 years.
After curing, the product retains elasticity, which allows the floorboards to expand freely with changes in humidity and temperature.
The substance does not shrink over time, which leads to subsidence of the flooring and the appearance of a creak.
The product should not contain elements harmful to humans that are released during the operation of the coating.

Criteria for choosing an adhesive for parquet

When choosing adhesive solution many factors are taken into account - the type of planks, their dimensions and characteristics, the type of base and its properties, etc. In order to choose the right product for the pairs "base - underlay" and "parquet - underlay", use our recommendations.

We suggest that you familiarize yourself with the features of the choice of solutions for some materials:

If you don't know which adhesive for parquet and underlay is best, buy a substance with high adhesion to lumber and cement.
After drying, a strong elastic layer should remain, which dampens the tension between the two materials.
Lower requirements are imposed on the connection of plywood with concrete, if the material is additionally fixed with self-tapping screws. In this case, the fastener will hold the shape of the canvas, and the glue will only fix the material in a stationary state. You can use a water-based substance, which costs much less than similar flooring compounds.
Piece oak or ash elements less than 70x420 mm in size without a stable wood coating are glued to the plywood with a dispersion adhesive.
High quality pre-coated parquet made from hardwoods (oak or ash) is recommended to be laid on plywood with one- or two-component polyurethane adhesives. Such compositions make it possible to avoid warping of the wood, which cannot be eliminated on already painted samples.
Fully lacquered boards are bonded with a product with maximum peel strength. Before work, it is necessary to conduct a test - fix the bar on the glue and, after drying, try to tear it off. Peeling of the lacquer coating after application of the load is unacceptable.
Uncoated piece blanks that absorb water well (from fruit trees, maple, beech) are attached to plywood with means the minimum amount water.
Wide slats with a locking connection system are afraid of moisture. Under the influence of water, overall lumber noticeably warps. The adhesive for such elements must remain elastic after curing, which reduces stress in long specimens. Also, the composition must have sufficient strength to securely fix the coating.
Massive boards up to 120 mm wide are glued to plywood with products that create an elastic layer of high strength and withstand the expansion of lumber. Large elements it is forbidden to fix with water-dispersion solutions.
Wide samples (more than 120 mm) are fixed with compounds that have good resistance to vertical separation. This is due to the fact that much greater stresses arise in the connection of parquet with the substrate than in other cases. The elasticity of the adhesive for wide boards does not play a role.
In the case of gluing wide dies (from 120 mm) on a fragile cement screed, it is necessary to use a composition with high adhesive properties. In this way, high rates of adhesion to the base at the molecular level are ensured.
If the boards are more than 120 mm wide and you plan to mount them on a solid base, use two-component adhesive Adesiv, with a high level of strength. A more costly option would be to lay the material on top of a woven fabric (multimol) which forms an intermediate layer between the screed and the deck and relieves tension between them. In this case, glue will be needed 2 times more, because. multimol is also laid on the glue.
A wide-format board from 120 m is glued to a solid cement base with polyurethane compounds. The connection is elastic, having a high tear strength.
To fix industrial parquet, you can use any type of adhesive that suits a particular type of flooring. The main selection criterion is the strength and elasticity of the connection.
