How to align the wooden floor under the laminate: the process of alignment of the floor with a screed, plywood and wedge-shaped lags with their own hands. Floor alignment technology plywood under laminate how to align the floor plywood under laminate

Laying of laminate is a fairly responsible process that requires a thorough preparation of the floor surface. All shortcomings in the work will inevitably lead to the deformation of the coverage and significantly reduce its service life. Floor alignment using plywood is one of the simplest and most affordable ways to make the surface perfectly smooth.

The floors from the laminate will be perfectly even with high-quality floor alignment and with this task is perfectly coping with plywood.

Laminate floor alignment

It will take:

plywood with a thickness of at least 1 cm;
drill;
glue for plywood;
electrolovik;
building level.

First of all, it is necessary to test the flattering floor in the construction level. If the differences are no more than 1.5 cm, then the laying of plywood can be made without using lags. First you need to prepare work. The boardwalk should be without fading places and discharged boards. If such drawbacks are detected, they are corrected by the replacement of the flooring. It will be worth it to further strengthen the floors with the help of screw screws, as well as to treat the surface of the primer with antifungal composition.

If you are planning to put the paneur to the concrete surface, then make sure it is good. To do this, take a piece of polyethylene film, take it to the surface with the help of a tape. If the next day you will find under the film condensate, it means that the concrete is still raw. The screed must be smooth and not to have significant drops, all chips and dents must be embedded with an aligning mixture. The floors are cleaned of construction waste, after which they are treated with a special primer of deep penetration on concrete.

Alignment of the floor plywood starts with antiseptic processing, this will further prevent the rotation of the material. Phaneru is cut into squares, the size of which will depend on the width of the sheet and the parameters of the room (most often the 75 cm panels are used). Align the boarded floor of the plywood fairly easy, the sheets are simply screwed up with self-draws. At the same time, it is necessary to leave a gap of 3-4 mm between the plates to avoid the surface deformation from the effects of heat and moisture. Between the walls and the coating, the gap is 1-2 cm. Alignment of the adhesive floor under the laminate does not imply putting the seams, such work is performed only if linoleum is used.

The finishing of the floor plywood starts from the inner corner of the room. The ranks have a displacement, the seams should not coincide and form a long line, it will make the coating fragile. The concrete tie panel is glued with special plywood glue, after which they are additionally fixed with dowels. If you put the sheets only on glue, then the likelihood is that in the future they simply drank, in turn, will lead to the deformation of the laminate. The rest of the laying technology is exactly the same as the festival decoration plywood.

Leveling floor under laminate on lags

It will take:

drill;
wooden bar for crate;
self-tapping screws;
building level.

Alignment of a floor having large irregularities is made on lags. To do this, you will need a wooden bar with a cross section of 10 to 4 cm. Since the wood has a property to deform under the influence of weather conditions, then the lags must be left in the room for a week for acclimatization and drying. After that, on the wall, the height of the future floor is noted, they do it with the help of a construction level. Lags are placed around the perimeter of the room, retreating from the wall by 2-3 cm, at a distance of each other at 40-50 cm.

Do not forget to check the height of the crate on the construction level, to put wooden wedges in the provision.

After installing the bar on the perimeter of the room, transverse struts are inserted, the design is fastened with self-draws. Between lags, you can install the insulation: first lay the waterproofing layer, then mineral wool or any other material, then steam barrier. After that, the sheets of plywood are screwed, while between them leave a small distance of 3-4 mm. The advice of the specialists outlined above will help you perform floor alignment without allowing serious mistakes and miscalculations.

It is no secret that when erecting many of our houses, the quality of the floors left much to be desired. That is why it is often starting to repair, we are forced to make the floor alignment under the laminate with their own hands.

And let this task not so complicated, as it may seem at first glance - still there are some subtleties.

Why level the floor under laminate

Before you begin to analyze the methods of floor alignment, let's figure it out - is it necessary to align the floor under the laminate?

As practice shows, in the overwhelming majority of cases, the floor is not just needed - it is necessary! And the main reason for this is the properties of the laminate itself.

The thing is that laminate laminated on the uneven floor, over time loses its operational characteristics:

Laminate panels can begin to be fed under the weight of a person;
The seams between the panels may dispense, opening the access of moisture to the unprotected inner surface of the laminate;
Under the influence of an increased load, the laminate locks can overcome and even give cracks.

In the most critical cases, when the surface with serious defects, it is possible even to bloat laminate or the appearance of cracks in the panels.

If you compare the parquet board and laminate, it will not be in favor of the last: if the parquet board is capable of partially compensate for the unevenness of the floor, then the laminate begins to lose operational characteristics rather quickly.

As a result, as it seems to us, the arguments in favor of being able to level floors under the laminate, quite enough. Now let's see which there are ways of alignment of the floor under the laminate.

Align the concrete base

Alignment of cement-sand tie

Concrete overlap is one of the most common grounds for laying outdoor coatings - at least in apartments. And in most cases, this overlap has a number of defects.

The most common defects of the concrete base under laminate can be attributed:

Cracks;
Skoles, potholes and sinks;
Concrete influx;
Detachment and abandoned areas;
Plane drops.

All these disadvantages require elimination.

Note!

As a rule, the instructions for laying the laminate allows its installation on the base, the drop in height is not more than 2 mm per 2 m. However, even in this case it is better to spend some time and resources so that this difference is to eliminate - as they say "

Best of all the alignment of concrete floor under the laminate to exercise using a screed - with the two receptions in two receptions:

When mixing a solution for a screed, a dry component is pour into the water, and not vice versa!

Restore the solution, pouring water into the thickened mixture, can not be in any case!

Pour the floor with the resulting solution, aligning it by lighthouses. We roll a solution with a special roller for removing air bubbles.
As soon as the solution "grab", we remove the beacon rails, and the holes in their place fill in the same solution.

Alignment of self-election mixture

The first, "rough" stage of alignment is completed.

We just have to wait for the mixture completely dry. Floor alignment with their own hands under the laminate is completed - you can go to the laying.

Align the wooden base

Cyclishing of rough floors

Aligning substrates are used in cases where the irregularities of the base do not exceed 4 mm - that is, When it is impossible to put the laminate directly on the base, and it is irrational to carry out full alignment.

To equalize floors under laminate apply:

Plug-based substrates (cork and cork-bitumen);
Polyethylene substrates;
Substrates from polyurethane foam.

It should also be noted that the price of most substrates presented in the market is quite democratic - so you can also lay them on the aligned basis. At a minimum - will not hurt.

In any case, the alignment of the floor under the laminate is a practically mandatory operation, from the quality of the execution of which the final result depends largely. And we hope that the information in this article will be useful for you when you start repairing in your home or apartment.

Modern floor covering (laminate, cork, linoleum) requires a flat surface of the base for its laying. In old buildings, the base often requires alignment. For this there are many methods, one of which is the alignment of the floor plywood.

For high-quality laying of outdoor material, there is a smooth base. It will save from the need to put felt or bars for equipment and furniture.

Wooden floor alignment plywood is necessary to remove bugs, depressions, as well as to eliminate curvature on the surface area.

Almost all outdoor materials are poorly reacting to the defects of the draft flooring. Laminate without a prepared floor will be creaked after a while, the board will be ignorant. On the linoleum, all the tubercles and flaws, which are under the finishing material, will be visible without prior alignment of the floor, plywood.

The installation of furniture and technology will also have problems when placing an uneven floor. A simple sofa installation can turn into a multi-hour problem with lining under felt legs, pieces of wood for alignment.

Plywood - floor material

Plywood - durable, multilayer material from wood. Due to the affordable price and excellent specifications, it is often used in construction.

This material is chosen as a rough floor due to many factors. Plywood has an affordable price per M2, well placed without additional costs of time and means for alignment of the floor. Due to the location of the fibers in different directions, this is quite durable material. It can be used not only to obtain a flat floor, but also to make small repairs to eliminate flaws and defects.

How to buy Fanur?

Plywood of different thickness

When buying plywood used for alignment, such parameters should be taken into account:

Brand;
Class;
Grade;
Thickness;
Material manufacturer.

Depending on the type of premises, you should prefer different stamps. For residential premises, give preference to the brands of FC or FSF. Such plywood is safe because there are no phenolic compounds. For wet premises, it is preferable to choose the FSF brands. Such plywood moisture resistant and resistant to mechanical exposure.

Differences of plywoods in varieties

The plywood class shows the level of free formaldehyde particles in the air. There are two classes:

E1 contains 10 mg of formaldehyde in 100 grams;
E2 contains in 100 grams of wood 30 mg of formaldehyde.

For residential rooms it is preferable to buy E1.

Plywood is made of 4 varieties. Material 1 of the grade is a high-quality phaneer. The fourth grade is a material with the presence of a large amount of flaws, chips and bitch. Professional masters recommend using for black flooring Faner 3 and 4 varieties. For the main floor, 1 and 2 varieties are preferred.

Varieties and classification

The thickness of the material is selected depending on the level of alignment, the curvature of the floor and the coating stacked above. Creating a draft floor for laying linoleum and carpet allows you to choose a thickness of up to 10 mm thick. Under the laminate or parquet for alignment of the floor requires a plywood thickness of at least 12 mm.

When choosing, focus on these indicators. If it is incorrect to choose a thickness, then noise insulation will fall and the floor will quickly come into disrepair.

The manufacturer determines the quality of plywood. European manufacturers guarantee excellent quality of the material produced. But Chinese production sheets do not always meet the requirements of the consumer.

Paul alignment scheme

Also plywood may have a polished or not ground side. If it is used as a draft floor, then it is stolen so that the surface is without grinding. This will ensure good contact with the finish material.

When using plywood as a finishing floor, the upper layer should be laid for the subsequent opening of varnish.

What tools will be required to work

Without the appropriate tool, it is impossible to spend high quality wooden floor alignment. To do this, you will need the following devices:

Perforator;
Screwdriver;
Floor level;
Roulette;
A hammer;
Lobzik;
Screws
Marker for marking.

Well, if there are even small handling skills with a building tool and material.

Before placing plywood, they estimate the state of the base and check the floor level.

Defects of concrete base and ways to eliminate them

The revision of the wooden base is to remove the tube, replacing the fasteners, update the board in the damaged part of the floor, the status assessment and replacement of underground communications if necessary.

The concrete base is checked for the lack of defects on the surface. The level is determined by curvature. Before laying plywood on a concrete base, they check the surface to humidity, covering the film for several days.

Styling on old lags

Experts report that depending on the height difference, the method of laying plywood sheets is chosen.

With a difference in an altitude of up to 2 mm, it is not required to align. Changing the floor level up to 5 mm on M2 allows you to align it plywood, laying it directly on the wooden base.

A big difference in the altitude of the concrete floor up to 8 cm requires the installation of a tape or point cage for plywood alignment.

The high floor drop requires dismantling the old coating and replacing it to the new floor.

Pistol

Knowing hard rules for equalizing plywood different types of floors, you can easily perform work with your own hands. When laying plywood as a fingerboard, sheets begin to mount from the middle of the room. Faluer must be attached to the phanesis at a distance of at least 2 cm from the edge of the sheet. After the process is completed, the coating is grinning and opened with varnish.

Creating a draft floor using plywood does not impose special requirements for fastening and locating sheets. If two layers of the material are assumed, then it is placed with the displacement of sheets to prevent the coincidence of the tops of the upper and lower row. There are a number of methods of flooring plywood sheets for laying on a concrete or wooden floor.

Laying sheets without lag

It happens that concrete floor requires not only alignment, but also insulation. For this, the option is suitable without the use of lag, which is considered one of the simple methods of alignment of the floor plywood. Working with plywood material begins only after it will hold it in the room for a few days to get used to the conditions of the room.

The base for laying and plywood leaf before you put it, processed by an antiseptic agent. To create a clearance needed on technology, the room has bars around the perimeter.

Sealing seams and irregularities

The location of the sheets of plywood on the floor is carried out so that they are with a displacement relative to each other (as when laying bricks). The material is fixed using screws evenly according to the protruding points of plywood.

All fasteners and seams are covered with sealant, after which the surface is sharpened.

For wooden floor, which is not loosened and in normal condition, you can also use plywood alignment without using lag.

Fastening self-proof

The floor of wooden boards is treated with a sealant or spacing material. It is leveling with sand or sawdust mixed on the resin. From above, a vapor barrier film is covered, on which plywood is already laid out.

In order to after fixing the plywood screws, they did not protrude above the coating, the holes are applied in several approaches. First, the hole is drilled along the size of the self-press, and then it is treated so that the screw of the screw was in terms of the surface of the plywood sheet.

Laying by lagum

Alignment of the floor plywood on a ribbon crate can be used for laying under laminate, tile or linoleum. Such a support is created using square sections and plywood sheets. Lags are placed in a step of 30-50 cm, and the indentation from the walls at a distance of 20-30 mm. Cross bars are fixed to lags in a checkerboard manner with screws. To give stiffness, you can fasten them with metal corners.

To create sound and thermal insulation between the crate, wept wood chips into the glue with glue. It dries such a mixture for 2-3 days. Also, it is also possible to use clamzite or mineral wool.

Laying between lag insulation

Phaneur to the support is fixed with self-draws. After that, any floor covering can be stacked.

The method of alignment of the floor plywood for mini lags is selected when there is a bias, or the surface drop is up to 8 cm.

Adjustable lags

The floor surface is placed to install bars and linings that create an ideal design for laying plywood sheets. This work requires careful calculations of the height of each support element with the layout of the floor and pre-fitting.

With such a flooring, all elements of the design will be different height. Work in such a way is not difficult, but requires a painstaking approach.

Scheme laying on point supports

This method of alignment requires the presence of supports, self-tapping screws, two layers of plywood coating and glue.

Initially, layers for marking and numbering on the basis of. Sheets are cleaned and on the wall marked the height of the first floor.

The base for the laminate should be perfectly even, otherwise during the operation of the panel will begin to creak and fuse, the locks are covered. You can perform alignment of the floor under the laminate in several ways, the choice of which depends on the type of base, the degree of its worn, restrictions on time and finance.

It is advisable to smooth the wooden floor only if the boards and lags are in good condition, there are no rotting sites, wide slots and other similar defects. If serious repairs are required, it is much easier to dismantle the floors to the draft screed and perform alignment along the concrete.

To prepare the board of the laying of laminate, you will need:

grinding or cyclical machine;
putty on a tree;
roller and brushes;
primer;
sheets of plywood, cement-chip plates, GVL or chipboard;
electrolovik;
roulette;
self-tapping screws and screwdriver.

First, the surface of the floor is thoroughly grinding or treated with a cyclical machine.

Clean the chips and dust, all small defects close up with putty. Then the base is twice the base, dried, fill the phaneer or other selected material. Self-tapping screws are used for the attachment, and the cutting material is performed by an electroll bison. Now it remains only to put the floor covering right.

Alignment of concrete floor

The easiest and cheap way to align the concrete floor is grinding. If the concrete base has no cracks, and the differences in height are not more than 5 mm, the surface is simply treated with a grinding machine or a grinder with a nozzle.

Then the floor is cleaned with a vacuum cleaner and ground. This option is not suitable for strongly damaged screeds, low-quality concrete and raw floors. In such conditions, the alignment is performed using a dry or cement-sandy screed, as well as ready-made leveling mixtures.

Floor Alignment Self-Laying Mix

Cement-sand I tie

For work it will be necessary:

water and construction level;
a container for the solution;
cement;
sand;
rule;
reiki for lighthouses;
trowel.

The new screed can be poured on the previous or directly on the ceiling plates. It depends on how much the base is damaged. If the old screed has irregularities more than 2 cm, but it is not necessary to dismantle it. Deciding with the base, proceed directly to the alignment of the surface.

Find the highest point of the floor and put on the walls of the label using a water level; Tags are connected to a horizontal line using a beat.
The floor is purified from dust and debris, laid a layer of waterproofing, reinforcing grid, put lighthouses made of metal plates to cement mortar. The distance between the beacons is about 1.5-1.8 m.
Installing beacons. In the photo, the floor is waterproof, but the reinforcement was not performed
Floor reinforcement grid. Lighthouses can be fixed with gypsum or alabastry quick-dry solutions.
Check the horizontal of the ridges by the construction level.
Cement is mixed with sand in a 1: 3 ratio, diluted with water to a pasty consistency.
The mixture is poured between the beacons, ranging from the far wall, and stretch it by the rule along the bands.

A day later, the lighthouses are gently taken out of concrete, mix a little cement mortar, and fill them with the resulting grooves. The surface of the spatula, the surface of the spatula, is drained, and then cover the floor with a film. Within 28 days, the screed should be protected from drafts, direct sunlight and regularly moisturize. As soon as the moisture content of concrete decreases to 5%, you can lower the substrate and laying the laminate.

Dry screed

For the screed, you will need a dry way:

level;
reiki for lighthouses;
damper tape;
GVL or Plywood;
glue, screws;
ceramzit;
waterproofing I am a film.

The base is pre-purified from garbage and close up with a solution of cracks, the surface is stuffed. When the floor is dry, start working on a tie device.

On the walls are placed the level of the first floor.
Fill the base of waterproofing M material, laying adjacent bands of the mustache.
With the help of the solution, the light racks are strengthened on the floor, they check their horizontality.
On the perimeter along the markup line glue the damper tape.
The space between the beacons is filled with a clay, which is moving through the rule.
The drying sheets are placed on top of the ceramzite, they jerk them on the seams.
Setting the first layer, proceed to the second: sheets are covered on the reverse side with glue and laid so to block the joints of the lower layer.
At the end, the upper sheets are connected with lower screws.

Dry screed team

Quite often, the floor under laminate is equalized by a dry team screed - on lags. In this case, the availability of bulk materials is not mandatory; They are used only if you need insulation.

For alignment, you will need:

level;
roulette;
hacksaw;
perforator;
dowels;
lags from timber;
Chipboard, plywood or gvl;
waterproofing material;
dampfer tape.

First you need to determine the level of the first floor and perform markup on the walls. If the base is absolutely dry, you can do without a waterproofing layer, but with high humidity of the screed, it is mandatory.

The film is filling the mustache, slightly roll on the walls, the edges of the material on the joints for reliability are sicked with scotch.
Lags previously treated with primer are laid on the floor, aligned horizontally using wedges or pieces of wood. The luggage tie is screwed by anchor bolts or with the help of a dowel, drill holes with a perforator.
On the lags on top of the self-tensions are screwed into one or two layers of the sheets of the sheath - chipboard, Phaneur, GWL.
The seams between the sheets are sealed with putty, and after drying it is grinding.

Alignment

This method of alignment cannot be called cheap, but it is he who has the greatest advantages. The pouring of the mixture is performed quickly and does not require much physical effort, the surface will also dry much faster than the wet screed. Such mixtures are used on rough bases with drops at an altitude of up to 5 mm.

The base is cleaned and determine the highest point. With the help of the level gauge make the label marker on the walls to which the floor should be poured. Next, the surface is ground and dried. If concrete is not the best quality, the primer is applied in two layers. After drying on the floor, the film is fill with the wall at the walls. Now the most responsible moment comes - the preparation of the mixture. Dramed with water dry mixture is necessary in exactly these proportions, and only mechanically. The wrong ratio of water and dry components or stirring manually will resolidate a leveling mixture, the appearance of bubbles, a reduction in coating strength.

If the area is large, the pouring solution is prepared by portions to use it before hardening. Pour the floor over the sections, ranging from a long corner. For reclining, a special spatula is used - rope, and then rolled the mixture with a roller with needles. Related sections should be poured with an interval of no more than 10 minutes. After filling, the floor is covered with a film and leave at least 3 days. During the dryer, it is necessary to eliminate the temperature differences, drafts, mechanical loads and vibrations.

Laminate is high-quality and inexpensive floors for the floor. This material appeared in the building materials market relatively recently. However, already deserved great popularity. It is connected with a beautiful and aesthetic species (the laminate in appearance is similar to parquet), durability, low cost, easy care and simplicity of installation. However, it is necessary for the stacking that the basis for which it will be laid was perfectly smooth.

If there is no laser level, then you can make this work using a simple construction level with water sensors. But with such a level work will be longer. The process is performed in the same sequence:

first, you should find the highest place at the floor wall;
then the level is applied to the wall and the strip along the lower edge of the level is drawn;
after that, the level is applied to the end of the line and the line is drawn until it goes throughout the perimeter of the room.

The next stage will be finding bugs and depressions on the floor. Two ropes stretch along and across the room level. If there is no contact with the floor in any place, then this level will be ideal. If there is still contact with the floor, then the level should be increased by several millimeters.

If the irregularities of the base do not exceed three millimeters, the substrate laying will be sufficient for their smoothing (the optimal version is a cork substrate). In all other cases, floor alignment is required under laminate.

The first way of aligning the wooden floor

The first and most common method is the alignment of the floor with plywood. This method is used when the floor drops are not more than 6 millimeters per 1 square meter of the floor. Installation of this material is characterized by its simplicity and is carried out as follows.

The second way of aligning the wooden floor

The second way is to use the lag, on which the floorboards are attached. This method should be used only if the old boards have become unusable, and the lags themselves are still in excellent condition. The process consists of the following steps.

Deleting old floor boards. Here everything is clear, with the help of a nail and a hammer, old boards are removed. At the same time it is impossible to damage the lags to which they are attached.
Warming grounds. The space between the lags is first falling asleep by a layer of clay, on top of which the foam is then placed. The insulation must be laid tightly, filling the entire free area between lags. The junctions between the plates can be treated with a special mastic or fill in the mounting foam.
Laying plywood. The final stage is the laying of plywood. Sheets are attached to lags with self-tapping screws. The step between the fastener should be 15-20 cm. After that, the substrate and laminate is stacked on the phaneer.

Third Wood Floor Alignment Method

The third method is putty PVA and sawdust glue. It is very simple when applied, but takes quite a long time. To do this, you need to take fishing of wood, PVA glue, wooden guides, a spatula with a width of 300 millimeters, a mounting level. Next, we recommend following step-by-step instructions.

Installation of guides. After determining the level of the future floor, we set the guides with the distance between them in 30 centimeters on all the floor area. You need to start from the other side where the floor has a smaller deviation from the level. At the same time, we mount the guides throughout the perimeter of the room.
Processing the surface of the primer. Initially, the surface should be treated with primer. The composition is applied with a brush.
Production of a spacion mixture. In PVA glue, you need to add wood sawdust. You need to add until the substance of the sour cream-like consistency is obtained. It is possible to stir it with a building mixer.
Application on the surface. It is necessary to apply the mixture with a thickness of no more centimeter, as it will give shrinkage. After applying the first layer, it is necessary to wait for its complete drying. Then we apply the following layer and so on until the necessary height of the applied putty will be obtained;
Laying plywood or fiberboard. When the putty finally dries, it is necessary to put a thin phaneer or fiberboard on top. These sheets are attached to guide self-drawing or nails. Also, it is also necessary to decide initially than you will be stuck a spacious floor. It is necessary so that the joints between sheets followed the guides.

Two more ways to align the wooden floor under laminate

The fourth and fifth methods can only be used if the wooden floor is really durable and reliable. They consist in equalizing the surface using a self-leveling mixture or concrete solution. Moreover, the second method has a significant burden on the base: it increases by about 75-100 kg per 1 kV. meter.

Step-by-step instruction:

It is worth remembering that these two ways are not the best options for the wooden floor. In the deflection of boards, the screed simply can crack. Therefore, it is preferable to choose the first three alignment options.

The final stage of any way immediately before installing the laminate is the laying of the substrate. There are various types of substrates (rolled type), but the principle of their installation is approximately the same: pieces of material rolls are stacked on the prepared base with a small overlap on each other, or the joint in the joint. The seams are squeezed with scotch. And after that, you can mount the laminate panels.
