Laying parquet with your own hands: step-by-step instructions for laying parquet yourself. Glue for parquet on a concrete screed: types, requirements and composition of the adhesive, as well as instructions on how to properly use glue for parquet Do-it-yourself screed

Parquet can safely be called one of the popular floor coverings since the times of Tsarist Russia. But laying technology parquet board on the screed, as well as on block parquet, has been significantly modified and simplified.

Finishing Decoration Materials made of wood continue to be one of the most wear-resistant and durable.

Laying parquet on concrete screed is carried out in several stages. But first, let’s understand the concepts of “parquet” and “parquet board”, since many ordinary people mean the same thing by these terms. However, these are completely different materials.

Parquet is solid wood planks planed to perfect smoothness, that is, solid elements Not large sizes. Length – 15-90 cm, width – 3-12 cm, thickness – 1.5-2.5 cm. Installation is carried out in several ways: with glue, hardware (screws, nails, studs), special staples or using a plastic cord, stretched in the body of the planks (tensile parquet).

But a parquet board is a multilayer coating of several segments. The top layer is valuable wood veneer up to 6 mm, coated with varnish or oil-wax compounds. The decorative part is glued to a slab of spliced ​​coniferous fibers. Bottom part It is a stabilizing layer of thinly planed wood. Dimensions: length up to 2.2 m, width – up to 25 cm, thickness – up to 14 mm.

Available with six types of Click locking system, but can be glued to the base or screwed with self-tapping screws. No surface treatment (scraping, grinding, priming, applying a protective layer of varnish, oil or wax) is required. In fact, after assembly it is a ready-to-use coating. The price per square meter of parquet boards is lower than the cost of solid parquet.

There is also a difference in the installation of coatings. For example, laying parquet on a screed is carried out only using staples or by tension method. This is due to the fact that parquet cannot be glued or nailed onto concrete - the difference in the degree of thermal expansion is too large. Finish coating it will simply swell, so it is recommended to lay the concrete first sheet material made of wood - plywood, chipboard, OSB, etc.

The technology for laying parquet boards on a screed allows for gluing and locking methods. The transverse arrangement of the fibers of each layer compensates for the thermal expansion of the material, so it is more resistant to changes in temperature and humidity in the room.

It is better to use dispersion or polyurethane adhesive for parquet boards on the screed.

Tools

To install parquet on a screed you will need the following tools:

1. Fine-tooth saw or jigsaw with wood blades.
2. Hammer (preferably a special parquet hammer).
3. Construction knife.
4. Drill, screwdriver.
5. Square, construction pencil, tape measure, cord.
6. Hydraulic level.
7. Restrictive wedges and a tamping block or wedge about 30 cm long.
8. Stainless steel spatula,
9. A scraper or parquet sander, a construction vacuum cleaner, a flat and angle grinder.

In addition to this you will need:

1. Waterproofing film.
2. Tinted wood putty or liquid for preparing a putty composition based on fine sawdust.
3. Adhesive primer for wood and deep penetration impregnation for concrete.
4. Paint and varnish materials for finishing parquet

Since the result will be a “floating” floor, that is, independent of the base, experts recommend not using varnishes that create a monolithic hard film on the surface. It is better to treat the parquet with oils or wax.

Step-by-step installation technology

Installation of parquet flooring using the glueless method is carried out in 4 stages.

Stage 1. Preparing the base

Surface concrete slab almost never meets the basic requirement - a perfectly flat, dry, solid base. Several methods are used to level it:

1. Screed with cement-sand mortar. It perfectly levels out all differences, damage and defects of the slab, but after application a technological break is required - at least 28 days. After this, it is recommended to remove the top layer - weak cement laitance - with a scraper or drum sander. After completion of the work, the base is primed with a strengthening compound. Permissible base humidity is no more than 6%. If you plan to install a “warm floor” system or simply insulate it, then all work is carried out at this stage.
2. Leveling mixtures: rough self-leveling floor or leveler on a gypsum or cement-gypsum base. These are industrial dry mixtures that require only dilution with water and application in a layer of no more than 1-5 cm. Drying time is 1-2 weeks, depending on the composition. Humidity – up to 1.5%.
3. Sandblasting or shot blasting and polishing using appropriate units. This quick way leveling, but before starting work, all cracks and cavities must be covered with quick-drying epoxy putty or filled with cement-sand mortar.

There should be no oil stains, paint coatings or debris on the surface. All excess is cleaned off, the surface is dust-free and primed with a strengthening compound. Permissible difference – no more than 1 mm for each square meter grounds.

Stage 2. Waterproofing and installation of perimeter barriers

A waterproofing film is laid on a properly prepared base. The strips are laid with an overlap of 15-20 cm, the edges are secured with tape. Substrates used under laminate or parquet boards cannot be laid under parquet.

Manufacturers of installation kits offer a special self-adhesive rubber cord mounted around the perimeter of the room. It replaces restrictive wedges during installation and at the same time perfectly compensates for the thermal expansion of the material.

Stage 3. Parquet installation

The actual laying of parquet on a screed requires compliance with certain conditions: the temperature should be room temperature, ranging from +18°C to 25°C, and the humidity in the room should be about 45-60%.

Parquet planks must be brought into the room a few days before installation to allow the material to acclimatize.

If the base is prepared according to all the rules, then the installation itself is not difficult. By analogy with a regular floor board, parquet is laid along the stream of light, that is, with the end side facing the window.

When installing on steel brackets (Junckers, Nexus), the procedure is as follows: fasteners are driven into the back side of each plank (with the exception of slats for the last row) so that half the length of the bracket remains free. The distance between adjacent staples should be 15-40 cm.

The planks are laid in a row, with the ends coated with PVA glue. After this, the second row is mounted in such a way that the free edge of the bracket fits into the adjacent plank, forming a rigid connection with the previous one. All other parquet flooring is also fastened together. The last row is not fixed with staples, but glued to the penultimate one.

Stretch parquet is installed slightly differently. Small diameter holes (less than 1 cm) are drilled in each plank at equal distances. On the base, the planks are assembled into a central row, from which the rest of the fabric will go. Each tenon of the tile is inserted into the groove of the previous one with an offset of 1/4 or ½ of the length, that is, the holes in the body of the parquet flooring must coincide. Protruding parts are cut off.

After the floor is assembled, plastic fastening cords are stretched from wall to wall. They are elastic, so they easily compensate for seasonal changes in the geometry of the floor covering.

Next, on one side, a fixing steel plug with a cap is put on the edge of the string and recessed into the mounting hole. Clamping mechanism the other end of the cord is pulled tight and secured with the same plug.

Stage 4. Sanding and sanding parquet floors

After graduation installation work Rough sanding of parquet is carried out using a parquet sanding machine with a drum attachment with a grain size of 40-60 units. Small defects and chips are first covered with putty. Then finer finishing is carried out using surface and angle grinders with a grit size of 120 units and above.

After finishing the grinding work, a primer is applied and protective covering. The gaps in the walls are closed with skirting boards.

How to protect parquet from moisture on the screed

According to the technology of laying parquet on a screed, its humidity according to standards should be in the range of 6-12%. But it’s better to play it safe and start the actual installation only when the humidity of the screed decreases to 4%.

You should not rush things and try to dry the flooded screed yourself, artificially– using a fan or heating devices. This will lead to uneven drying of the base, causing the base to crack and sag.

It is worth being patient and waiting for the end of the technological break. And only after this, cover the floor with a waterproofing film, not a vapor barrier, and gluing the joints.

What to do if the parquet bursts

Unfortunately, cracked planks high-quality restoration are not subject to Ideally, they should be replaced immediately after a defect occurs. But this is not always possible, so as a temporary measure you can use ready-made putty or tinted silicone sealant. You need to work carefully; the treated area should not be loaded for 2-3 days for complete drying.

After completing all installation work, do not forget that the parquet needs maintenance. Purchase a special line of care products from your flooring store. wooden coverings. Periodically (at least once a year) the oil-wax protection also needs to be updated. Then the parquet floor will serve you for a long time and will delight your eyes with its aesthetic perfection and the warmth of natural wood.

The floor covering must be laid so that general interior looked harmonious and beautiful. The most the best option For any type of room there was always wood. Natural or wood-imitation coverings, such as parquet boards, look especially beautiful on the floor. However, it must be placed correctly. If the technology for laying parquet boards is followed, then this flooring will please you for a very long time.

Parquet boards are made from several layers of wood, which are joined together with a special glue. This is done to ensure that the floor covering is as durable as possible. A peculiarity of the production of the product is that each subsequent layer is glued to the previous one so that the fibers are located at right angles.

More durable and at the same time cheaper wood is used to make the lower layers. The upper part of the planks is made of more expensive wood. You can install the presented facing material yourself. Naturally, this will require simple devices. In addition, the technology for installing parquet boards must first be considered.

Advantages

So, the presented material can “boast” of the following advantages:

• High strength and reliability.
• Absolute environmental cleanliness.
• Excellent wear resistance.
• Remarkable decorative properties.
• Naturalness.
• Possibility of self-installation.

Naturally, any wood under the influence of negative factors can lose its technical properties, succumb to rot. However, proper care and proper protection will help extend the life of the parquet.

Types of parquet boards

The material can be classified as follows:

1. Solid parquet board. This flooring is made from a single piece of wood. A tongue and groove are cut out at the end part, with the help of which the planks are connected. In the production of such material, both coniferous and deciduous wood are equally often used.
2. Multilayer parquet board. Here they are used simultaneously different breeds tree. Thanks to this, manufacturers can achieve the required technical characteristics.

Even at the production stage, the presented cladding is treated with special antiseptics that protect it from mold, rodents and rot.

What installation methods are there?

Laying parquet boards with your own hands can be done in three ways:

• Zamkov. This type of connection can also be called “floating”. The planks are connected only using grooves and ridges. No additional fasteners are used. In this case, if necessary, the floor can be disassembled or the damaged element can be easily replaced.
• Glue. In this case, special glue is used to fix the material.
• Mechanical fasteners (nails, screws, self-tapping screws). This method of connecting a parquet board to a base is the most reliable.

Before laying a parquet floor, you need to decide which methods of laying parquet boards will be used based on the specific use of the room and the preferences of its owner. You can also combine several mounting methods.

Preparing the base for work

This procedure largely depends on the type of subfloor. It can be wooden or concrete. In any case, the base must be smooth, clean and dry. If the base is wooden, then you first need to check it for the presence of level differences, dips, rotten boards or logs. To eliminate minor errors old layer there is no need to remove wood. It is enough to cover the cracks with special putty.

To smooth out minor flaws, you can use a sander or sander. If you hear a squeak when walking on the floorboards, and you also feel their movement, it is advisable to attach them more firmly to the joists. If the master has little time to level the base, then you can use. This material helps to quickly eliminate all differences. The plywood must be screwed with self-tapping screws, recessing the caps inside the sheet. Small gaps must be maintained between the sheets to avoid deformation of the leveling layer.

Before you begin laying the parquet boards with your own hands, screwed plywood, as well as other wooden elements requires treatment with an antiseptic. After this, you are allowed to begin the cladding installation procedure.

If the subfloor is concrete, then to level it you will need to pour. Naturally, before this, the base is checked for cracks, chips and weak spots. Before pouring a new screed, the old subfloor must be primed. Please note that the screed can be either wet or dry. The second option involves installing the same plywood. After the screed has hardened, you can lay the parquet board.

Installation features

If the methods for laying parquet boards have already been selected, the material has been purchased, and the base has been prepared, you can begin installing the cladding. However, we should not forget about some nuances:

1. The cladding should not be laid on the floor in the bathroom, toilet or kitchen, as the material does not react well with moisture.
2. After delivery to the apartment, packages with the product must remain indoors for at least 2 days.
3. During installation, it is necessary to create appropriate conditions in the room: humidity 35-65%, air temperature at least 18 °C.
4. Before attaching a parquet board to plywood or screed, you must first lay the underlay.
5. Laying parquet boards on glue, screed or plywood is done only after treating the surface with a primer, which improves the adhesion of materials.
6. It is advisable to lay parquet flooring in the direction of the light rays.

It provides for the following procedure for carrying out work:

• Cleaning the screed from dust. A powerful vacuum cleaner will be useful for this.
• Laying waterproofing film. The thickness of this material should be 200 microns. It spreads overlapping stripes, and one should not forget to extend the material onto the walls by 5-6 cm.
• Installation of natural substrate.
• Laying parquet boards diagonally or in another way starts from the farthest and most long wall. It is necessary to insert wedges between the first row of boards and the wall to create a technological gap. In the next row, the remaining cut part of the parquet strip is attached first. In this case, the drawing is taken into account. In order for the planks to “sit” well in place, you can use a mallet and wooden block. The adhesive method involves applying a special composition to the back side of the element and fixing it to the base.
• Installation of baseboards. It is screwed around the entire perimeter of the floor.

If during installation you need to trim part of the board or cut a hole in it, it is better to use a jigsaw for this purpose. Visual video to help you with installation:

Caring for this type of flooring involves using a well-wrung out damp cloth and a vacuum cleaner. If there are stubborn stains on the floor surface, you can use special means for washing, designed specifically for this type of floor covering. If you follow the technology for installing parquet boards on a screed or wooden base, and proper care, the floor will last a very long time. Add comments to the article, and finally, a useful video:

Laying parquet on a concrete screed is carried out in several ways: with and without plywood backing. Before you begin the installation procedure, you should find out what the differences between them are, and in which case you cannot do without a plywood layer. If you follow the entire installation algorithm correctly, the result will be a strong, stable and durable coating.

What is the difference between parquet and parquet boards?

Although the names are quite similar, parquet and parquet boards are not the same thing. The only similarity between them is that both are made from natural wood. But they differ significantly from each other in their design:

1. Parquet is made from solid wood, in this case, not the most wasteful varieties are used. Thickness finished product fluctuates between 17-20 mm.
2. Parquet board- This is a three-layer material in which the bottom and middle layers are made from the least valuable wood species. But valuable wood species are used to create the top layer. The average thickness of the finished product is 14-15 mm, of which only 4-5 are valuable species, therefore the cost of the material is lower compared to parquet.

Operational differences should also be noted:

1. Parquet reacts sensitively to any changes in the external environment. Therefore, in the room where parquet is installed, it is necessary to regularly monitor the level of humidity and temperature. Direct contact with water should be completely avoided.
2. Parquet is more repairable than parquet boards. It can be sanded and varnished several times, so it returns to its original appearance. In the case of a parquet board, such a maneuver can happen, but no more than twice. It all depends on the thickness of the decorative layer.
3. Due to the fact that the top layer of the parquet board is too thin, it quickly wears off due to intense loads.
4. Parquet boards are practically maintenance-free. It can be washed with a wet cloth, but parquet cannot.
5. The process of laying parquet is more labor-intensive than parquet boards, although parquet is easier to repair and restore.
6. The parquet board does not require any work after installation, as it is already equipped with a decorative coating. Parquet, on the contrary, needs sanding and varnishing.
7. The service life of parquet is 70 years or more, while parquet boards will completely wear out after 15-20 years.

Tools for work

Laying parquet boards on a concrete floor should be carried out only after the surface of the base has been completely cleaned of old coating, oil stains, construction and household waste. The surface must be free of dust, carefully cleaned and treated with a primer.

Important: If you have just poured a concrete screed, be sure to give it time to dry. If the thickness of the concrete base is up to 5 cm, then drying will take from 4 to 6 weeks.

To assemble parquet, you will need to use the following tools:

• parquet hammer;
• jigsaw or saw with small teeth;
• sharp knife;
• materials for marking (tape measure, cord, pencil);
• level;
• drills;
• limiters and tamping block;
• spatula made of stainless material;
• scraping apparatus;
• construction vacuum cleaner;
• flat and angle grinder.

In addition, you will need to use a waterproofing film, wood putty, adhesive primer, concrete impregnation, and special parquet varnish.

Choosing adhesive for parquet

Parquet boards are laid on a concrete screed using special adhesives that differ in technical characteristics and composition:

1. Dispersion glue. Environmentally safe, no aggressive chemical compounds or odor. Contains water, so it is recommended to use it for laying parquet made of moisture-resistant wood (larch or oak). This glue is not suitable for beech, maple, and ash wood. It takes quite a long time to dry.
2. Synthetic glue. It contains synthetic resins and rubber. It is durable, elastic and reliable, recommended as an adhesive for parquet. The glue hardens in about 15 minutes. As in the first option, adhesion rates are not high, which is why increased demands are placed on the primer and screed.
3. Two-component adhesive. It is highly expensive and can be used for any coating. Before use, the hardener must be mixed with the adhesive. In liquid form, it releases harmful chemical compounds. Therefore, it is extremely important to work within the means personal protection respiratory organs. After hardening, the glue is converted into a hard, inelastic material, which is why its scope of application is somewhat narrowed.
4. Polymer glue. This adhesive has average effectiveness and hardens under the influence of moisture in the air. It contains MS polymers and has a sound insulation effect. Disadvantages include a long drying period and a strong unpleasant odor.
5. One-component polyurethane adhesive. After hardening, it remains elastic. This glue can be used for both parquet and plywood. It does not allow moisture to pass through and prevents the possibility of swelling of the lamellas. It has high adhesion to many building materials, dries quickly, and can be used with any type of wood, regardless of how it reacts to high humidity.

Important: When choosing glue, pay special attention to the following: specifications, such as minimal shrinkage, elasticity, long service life, minimal amount of water.

Step-by-step technology for installing parquet on a finished screed

Before starting work, it is necessary to clean the room and clear it of household waste. There should be no oil or paint stains on the floor. You should prepare all necessary tool, materials, study the technology of laying parquet boards on a screed.

Preparing the base

A concrete surface is almost never perfectly flat, dry and hard. In order to level it, experts use several methods:

1. Screed using cement-sand mortar. It allows you to perfectly level out all differences, damage and defects. But after applying it, it is necessary to interrupt everything for at least 28 days. engineering works. Then the top layer of the screed is removed using a scraper or grinder and primed with a reinforcing compound. The humidity of the base should not exceed 6%. If you decide to install a “warm floor” system or simply insulate it, then all work related to this must be carried out at this stage.
2. Leveling mixture This is a rough self-leveling floor on a gypsum or cement-gypsum base. The coating layer is usually 1-5 cm. It is recommended to dry it for about two weeks, everything will depend on the composition. Permissible humidity should not exceed 1.5%.
3. Sandblasting, polishing. This method of leveling the surface is considered the fastest, but before it begins, it is necessary to close all cracks with quick-drying putty or fill the hollow pits with cement-sand mortar.

A waterproofing film is laid on the prepared base. The strips should be laid on the parquet board with an overlap of 15-20 cm, and the edges should be secured with tape. Under the parquet there should be no underlays used under laminate or parquet boards. In modern markets you can find a self-adhesive rubber cord and install it around the entire perimeter of the room. It serves as an excellent replacement for restrictive wedges when laying.

Laying flooring material

Before laying parquet boards on a concrete floor, it is recommended to comply with certain conditions. The air temperature should not go beyond 18-25°C, and the humidity in the room should not exceed 45-60%. Bring the parquet planks into the room a few days before installation. This way the material acclimatizes faster. Like a regular floor board, parquet is laid along the light streams emanating from the window.

If the parquet is mounted on steel brackets, it is necessary to drive fasteners into the back of each plank so that half the length of the bracket remains free. The distance between the staples should be about 15-40 cm. Lay the planks in a row, not forgetting to coat the ends with PVA glue. When installing the second row according to the technology, make sure that the free edge of the bracket fits into the adjacent plank, thereby forming a strong connection with the previous one. All other parquet flooring must be fastened together in a similar way. There is no need to fix the last row with staples; it should be glued to the penultimate one.

When installing stretched parquet, each plank must be drilled. The holes should be less than one centimeter in diameter. You must start installing the planks from the central row. The rest of the canvas will come from it. When joining tiles, insert the tenon into the groove offset by ¼ or ½ of the length. Make sure that the holes in the body of the parquet flooring match. Cut off the protruding parts.

After the floor is assembled, it is necessary to stretch fastening plastic elastic cords from wall to wall. With their help, it will be possible to easily compensate for changes in the floor covering that occur due to climatic conditions. One side of the string is secured with a plug. The other end of the cord is stretched and also secured with a plug.

It is difficult to argue with the opinion of craftsmen who claim that a real wooden floor can only be made from parquet or parquet boards. Traditionally, parquet is laid on a prepared substrate or on joists. Modern quality multilayer parquet board allows you to lay the material even on concrete. The pleasure is not cheap, but the quality of the coating is very high. The outer surface of the flooring is lined with inserts made of hardwood, traditionally used for the manufacture and installation of parquet. Therefore, the floor turns out to be beautiful and durable, but on one condition, the master who undertakes the installation must perfectly understand how to lay a parquet board on a concrete floor.

What is parquet board

The classic version of a typesetting covering made from small parquet boards is quite rare today, primarily due to the high price of the material. A board 400-500 mm long and 40-50 mm wide was cut from solid oak or elm, carefully finished and sorted according to the pattern and surface texture. As a result, high-quality oak parquet cost an astronomical amount of money; in order to lay a parquet board, it was necessary to find an experienced craftsman. Material required daily care, periodic grinding, sanding and wax polishing.

Modern parquet is much easier to use. Manufactured in two versions:

• In the form of a solid thick parquet board made of solid oak or beech wood;
• In the form of a lamella glued together from a pine base, with an outer insert made of hardwood.

For your information! The dimensions of a parquet board are several times larger than the dimensions of a classic parquet fragment, it is much cheaper and easier to handle; it is quite possible to lay the board on a concrete floor with your own hands.

Solid wood parquet is much more expensive than a three-layer coating, so it is used as finishing expensive repairs, offices, apartments and executive premises. At the same time, glued parquet boards, even with external cladding made of expensive types of wood, are becoming increasingly popular due to their relatively affordable price and the ability to lay the material yourself.

Parquet boards are produced in the form of lamellas up to 250 mm wide, 2200 mm long, and 12-14 mm thick. The top layer of oak or beech may have an additional oil or varnish coating, which prevents the most sensitive part of the parquet from absorbing moisture and subsequent warping. A tongue and groove is cut on the sides of each lamella, allowing the parquet boards to be laid into one hard floor covering.

Laying out two-layer parquet boards, laying technology

There are several ways to lay a parquet board on a concrete floor:

1. On a plywood base with fastening the lamellas using self-tapping screws or pneumatic nails. In fact, this is the most complex and durable way to lay parquet boards and make the floor as durable and reliable as possible. The only drawback of this method is the inability to disassemble the parquet floor in the event of force majeure;
2. Lay in a floating or loose manner. In this case, the parquet board lies freely on the surface of the concrete floor, without attaching the laid board to the base of the plywood base;
3. Laying parquet lamellas on adhesive base. This method is used for very high concrete floors, when it is not possible to lay a backing layer of OSB or plywood.

The worst enemy of a parquet board is open moisture and water condensation, so craftsmen prefer not to lay parquet directly on a concrete floor, even if there is an intermediate layer of primer and protective film. A cold, damp concrete surface always becomes a place for condensation of water vapor, causing swelling and warping of the supporting surface of the parquet board.

Experts recommend laying parquet on a wooden, plywood or cardboard base for two reasons. Firstly, in this way it is possible to additionally compensate for surface defects for laying parquet, and secondly, the adhesion of the base of the parquet board to the concrete base of the floor is improved.

Before making a choice on how to lay the parquet board, it is necessary to bring the quality of the concrete surface to the most even state, without bumps and humps.

Preparing the concrete floor surface for laying parquet

High-quality preparation of a concrete floor before laying parquet requires enormous patience and a significant investment of time and effort. Assembling the flooring from parquet boards is often much easier than leveling it concrete base. But it is extremely important to level it. A parquet floor is not even a laminate or linoleum, which can be laid on almost any concrete screed. On a base with small flaws, with depressions and a slope, a laminate coating can be laid, and only if a high-quality substrate is used.

Why is it so important to lay parquet on a perfectly flat and rigid base surface? The fact is that the behavior of a parquet board is fundamentally different from a classic parquet board. A relatively hard, large parquet board on an uneven surface will certainly begin to “play” under your feet or under the weight of furniture. As a result, the joints between the parquet flooring will automatically undergo shear and fracture, which will ultimately lead to the destruction of the lock and detachment from the adhesive base.

To install a high-quality parquet board that will last for a couple of decades, you need to do the following:

If the error is within the normal range, you can lay parquet; if during all the manipulations it was not possible to level the concrete surface, then it makes sense to install a self-leveling self-leveling floor, which will allow you to lay parquet without a base or with a minimum thickness of lining material.

If the concrete floor is on the ground floor, and the height allows you to lay another 20-25 mm of leveling mixture, then it would be more rational to use a self-leveling base. Otherwise, you will need to lay cushioning material made of OSB, waterproof plywood or very dense corrugated cardboard. The thickness of the lining is selected as ¾ of the thickness of the parquet board.

Laying parquet boards

Before laying the plywood sheets, the concrete is treated with a thin layer of acrylic primer. In order to lay the plywood base as firmly and accurately as possible, the consistency of the glue should correspond to thick sour cream. It is applied to the concrete with a brush and rubbed with a wide steel spatula.

After this, you can lay down sheets of lining material. The procedure is quite labor-intensive, but there is no need to rush. As in the case of leveling a concrete surface under a parquet board, when laying plywood you should try to get the most even horizontal surface possible. Sheets are stacked chessboard or in a “running start”, the seams are sealed with sealant on acrylic base. After about two days, the seams and the plane of the lining layer are checked with a horizontal level and sanded with a belt sander.

Installation of adhesive-based parquet boards

If the concrete base has been leveled to the required surface quality, then it makes sense to lay the parquet board directly on the concrete using glue. With this solution, it will be possible to lay the package faster and better than when using a wooden backing.

For gluing parquet, two types of glue are used - acrylic resin and two-component polyurethane based. Both glue options allow you to lay parquet with high quality adhesion, so it is not necessary to buy the most expensive brands of glue. Previously, parquet and linoleum were laid on a concrete floor using bitumen-styrene mastic, used for waterproofing roofing coverings. The quality and durability of this option were quite high.

Before laying the first two rows, restrictive wedges are installed along the wall, providing a gap of 10-12 mm between the first row and the vertical surface. The glue dries quickly, so it is prepared in small portions and, if possible, used immediately. The adhesive layer is applied with a notched trowel, as in the photo, only on an area the size of a single board, after which the first parquet flooring is laid out with a spike against the wall. In addition to the supporting surface, the glue must be placed in the lock so that the joints between the parquet boards are also glued.

Each subsequent row must be trimmed and laid so that the end seam between the boards is shifted by 1/3 of the length relative to the previous row. Each board must be correctly connected to the previous row, and most importantly, it must be carefully aligned in a horizontal plane and tacked.

After installation, excess glue is removed and the seams are sealed with acrylic sealant. After 4-5 days you can start finishing parquet

In a similar way, you can lay a parquet board on a backing made of plywood or pressed fiberboard.

Free laying parquet

Wooden lined High Quality parquet boards can be laid without the use of nails or adhesives. Typically, such a coating is laid for small rooms, in which the difference in temperature and air humidity can reach significant values. For example, a glazed terrace or a living room.

In this case, the parquet flooring is assembled from individual boards, similar to a laminate flooring. Such parquet is held on the surface of the lining layer only due to the interlocking of the locks, which allows it to expand freely when heated or increased air humidity.

Conclusion

Before you begin laying the flooring, the parquet material must spend at least a week in the room where it is intended to be laid. The boards will be typed required level humidity, and the floors will not creak or deform due to excess or lack of moisture. After laying the parquet, you will need to sand the seams and pre-sand the surface. Next, all that remains is to treat it with mastic or apply a varnish coating.

Parquet is valued for its wear resistance, durability and attractive appearance, and at the same time it is one of the most expensive and capricious floor coverings. His professional installation It will also be expensive, so many people decide to lay parquet flooring themselves. Strict adherence to the instructions will allow you to avoid errors in work and ensure the perfect condition of this luxurious coating on your surface. long years. Let's look at the most commonly used technology and find out how parquet is laid on a concrete screed

Parquet and its budget alternative

Parquet is called planed, perfectly smooth boards made of solid wood. This material It is one of the elite ones, and accordingly its price is quite high. The planks have the following dimensions:

• length – from 15 to 90 cm;
• width – from 3 to 12 cm;
• thickness – from 1.5 to 2.5 cm.

More affordable and less picky in relation to subfloor The material is parquet board. It is a multi-layer coating, the top layer of which is made of valuable wood veneer, and the 2 lower layers are coniferous species wood The length of such boards is up to 220 cm, and the width is up to 25 cm.

Is parquet suitable for your apartment?

Laying parquet on a screed – effective solution for floor covering equipment. However, before making it, the reasonableness of such a decision should be carefully assessed. After all, wood is natural natural material, very susceptible to temperature fluctuations, high humidity. Therefore, it is reasonable to use it only in rooms with guaranteed suitable temperature and humidity conditions.

At excessive dryness the parquet dries out, loses its shape and appearance, cracks form, and if you lay it in a damp room, the parquet planks will rise when saturated with moisture. Optimal parameters:

1. Humidity 40–60%;
2. Temperature not less than +18°C, but not more than +24°C.

How is parquet installed?

The technology of laying parquet on a concrete screed, provided all the necessary nuances are observed, is not particularly complicated. Conventionally, the process can be divided into several stages.

• Checking the quality of the screed or installing a new one.
• Waterproofing.
• Plywood flooring (chipboard, OSB).

Important! Parquet can be laid directly on the screed only if the conditions of low humidity of the base are met - up to 6%, or even better - up to 3%. It is highly recommended to use an additional layer of plywood, chipboard or OSB.

It is recommended to lay parquet on a screed without plywood in two ways - using brackets or using the tension method. It is not worth gluing the strips because big difference in the thermal expansion of materials. If you still decide to use an adhesive composition, it must be elastic.

• If necessary, sanding and varnishing the parquet.

Parquet boards can be safely laid on a concrete floor without using a plywood backing. To find out, we recommend watching the training video:

Preparatory stage

Cases when the surface of the base (concrete slab) is perfectly flat (permissible difference is no more than 1 mm per m2), hard and dry, are extremely rare. Therefore, laying of block parquet is carried out not on concrete, but on a cement-sand screed, or its equivalent.

Additionally, the subfloor is inspected for cracks and other defects, which are filled with putty or cement mortar.

Please note that before laying parquet, it is necessary to completely clean the surface of the base from remnants of old coatings, oil stains, construction and household waste. It must be removed from dust, carefully cleaned, and treated with a primer.

Important! A freshly poured screed should be given time to dry. If its thickness is up to 5 cm, then it will take 4–6 weeks.

Waterproofing

After the base has been prepared, a special film with waterproofing properties should be laid on it. The strips are laid with an overlap of approximately 20 cm. The edges are secured using tape, and the film stock is placed on the wall for laying under the baseboard. The underlay used during the installation of laminate or parquet boards is not suitable for parquet.

The role of restrictive wedges is performed by a special self-adhesive rubber cord, which is installed around the perimeter of the room. The same element compensates for possible thermal expansion of the slats.

Plywood flooring

If you decide not to take risks and lay a stabilizing plywood layer on the screed, which will protect the parquet from swelling and damage, do the following:

• Thick plywood sheets (the thickness should be 2/3 of the thickness of the parquet) are sawn into squares (40 × 40 or 70 × 70).
• The screed is treated with a primer.
• Special glue is applied to the surface.
• After such processing, the plywood squares are laid, and it is done with an offset, and gaps of 3 mm are left between the sheets.
• The gap between the laid plywood and the wall should be approximately 1 cm. Upon completion of the work, it must be filled with sealant.
• Before installing the parquet, the plywood is sanded to eliminate possible differences.

Laying parquet planks

The parquet planks are brought into the room where the work will be carried out several days before it begins for the purpose of acclimatization.

With proper preparation of the base, laying parquet on a screed should not cause any difficulties. This process must begin from the end side towards the window.

Installation of parquet with brackets

If we lay planks on a screed using steel brackets, then the procedure is approximately as follows:

• To the wrong side of each plank, with the exception of the last row, at a distance of 15–40 cm from each other, we stuff special staples, which can be purchased at hardware stores. This manipulation is performed in such a way that half the length of the staple remains free.
• We coat the ends of the parquet planks with adhesive (you can use PVA) and lay them in a row.
• The second row is installed in such a way that the remaining free edge of the bracket fits securely into the adjacent plank.
• We repeat this process by analogy required amount rows.
• The final row of planks is glued to the previous one without using staples.

Tension parquet

If we're talking about about stretched parquet laid on a screed, the procedure is as follows:

• A hole 1 cm in diameter is drilled in each plank.
• The central row is assembled, which will later become the basis for the entire canvas.
• The tenons of the parquet planks are mounted in grooves offset by a quarter or half the length, so the holes made in the body of the parquet flooring must coincide.
• After assembling the floor, it is necessary to stretch special fastening cords made of plastic, which have necessary indicator elasticity to tolerate possible seasonal changes in the geometry of the material.

When using plywood flooring laid on a screed, the planks are attached to it using parquet glue applied with a special spatula. Next, it is recommended to shoot the parquet flooring along the edge - several pins or nails per element. This will not only make the fastening more reliable, but will also allow you to squeeze out excess glue and ensure a more uniform fit of the planks.

Final processing of parquet

After installation, the floor covering must undergo a rough sanding procedure. Before it, all minor defects, cracks and chips are covered with putty. Then the base is refined using fine-grained grinding machine attachments.
