Alignment of floor under laminate. How to better align the floor under the laminate methods of floor alignment under laminate with their own hands

Flooring from laminated pressed panels can be able to serve from a dozen years, even without cosmetic maintenance and repair, but under one condition - the base for laminate before the installation process must be conscientiously align in the horizontal plane with the highest possible accuracy. The alignment of the floor under the laminate will take several days, but should not be hurry, in this case the hurry can do it much more expensive.

Methods for equalizing the base under laying of laminate

Leveling or alignment of the floor plane, in fact, is one of the most time-consuming and painstaking stages of laying laminate. Before deciding how to align the floor under the laminate, it should be remembered that the laminate itself is just thin laminated fiber plates, from how precisely the load will be transmitted to a concrete or wooden base, depends, whether the locks will disperse and whether the slots will appear. Freshled outdoor coverage.

Align the floor under the laying of laminate can be one of the classical ways:

Laying auxiliary or roughing floor of gypsumless plates, plywood or OSB;
Performing a concrete or dry screed on the processed base surface;
With a self-leveling self-leveling composition.

For your information! The main task of the floor alignment is the elimination of the differential or slope of the base for the installation of the future laminate.

Otherwise, the floor covering from laminate laminate over time smoothly slides in one direction, which will lead to the disclosure of locks and the swelling of the lamellae. Large bumps and hollows on a concrete surface or a milking floor must be cut, the trifle partially compensates for a soft substrate.

The leveling technology largely depends on what kind of gender is assumed to install the coating. The most time consuming is the process of preparing a wooden militant floor. Sometimes to select the optimal method, how to align the wooden floor under the laminate, leaves more time than on the laying of the coating itself.

Easy way to align the surface of a wooden floor

In very rare cases, the shaft surface can be used directly for laying laminate plates. Even the fresh wooden floor always "plays" on the lags, has a not perfectly smooth surface, and most often in the process of a set of natural moisture, the lags and the board are deformed, which led to a deviation from the initial position.

The easiest way to align the wooden floor can be in the following sequence:

Climbing gaps between the boards so that none of the flooring is in suspended state;
Cresses and grind the surface so as to remove the curvature and bring close to the horizontal position as much as possible;
Stacked the draft floor from OSB plates or plywood.

Tip! Many masters are trying to align the wooden floor with a solid surface grinding on a parquet cycle manner, without further styling of the draft floor.

In this way, you can align the boarded floor of good quality with the perfect horizon, while the surface of the surface requires a professional grinding machine with a thorough control of the horizontal level. In addition, such cases will need to lay a special leveling substrate under the cork tree laminate.

In conventional grinding, the horizon will not work, therefore, so as not to weaken the floor, the grinders are cut off the most protruding edges of the joints and parts adjacent to the walls. Next, the ground pieces are painted with a protective composition, and stacked the plates of the draft floor.

Ways to align concrete floor under laminate laying

The laying technology of the laminate coating was originally developed exclusively for laying on a prepared concrete surface. Therefore, if concrete does not have obvious defects in the form of a littered horizon, align such a floor the easiest all with grinding, fill or styling rough and intermediate coatings. But, before aligning the floor under the laminate without a screed, it is necessary to perform a control measurement to make sure the accurate geometry of the concrete surface.

Pre-concrete is thoroughly cut and cleaned from the eyes visible to the eyes and cones, garbage, dust removed. After that, the highest point of the surface is determined, and the horizon line is applied using the construction level around the perimeter of the side walls. If the difference in the height of the ground floor does not exceed 2 mm, you can lay a self-leveling substrate and start up the installation of the laminate.

Otherwise, the floor under the laminate will have to be aligned with a screed, a bulk or frighting of the insulation.

Filling floor alignment of the barrier layer

It is easier and faster to align the concrete floor under laminate with a concrete screed or fill with self-leveling mixtures. Alignment technology is largely similar, but there are nuances and features. The most difficult stage in both cases is the installation of beacons or profiles by which the upper layer of fill or screed under laminate is formed.

Before the arrangement of the screed, concrete floor is placed by rolled waterproofing, with overlap of cloths at least 10-12 cm. The joints are sampled by mastic, and the edges of the insulation around the perimeter of the room are lifted and overlooked on the wall, to the height equal to the double thickness of the future screed. The perimeter of the room and the concrete surface under the adoption of waterproofing can be additionally handled by primer.

After waterproofing, it will be necessary to install, align on the level on the walls and secure the beacon with alabaster from the profile. To prevent the surface cracking, the screed is always amplified by a thin reinforcing grid. For a tie prepare concrete based on cement M500 with sand-sand, a ratio of 1: 3 and the additive surfactant in the amount of 20g on 10 liters of water.

When forming a screed, the concrete mixture is gradually thrown into the moistened floor and stretched with a rail - rule from a long corner towards the entrance to the room. The first layer of concrete is rough, after stacking it is slightly trambed to improve the adhesion to the base floor. The second layer is more liquid, a polyvinila acetate emulsion is added to the concrete, so that the surface on which the laminate will be laid is as smooth and smooth.

Self-leveling solutions are poured into two layers. The first layer is required in order to align and compensate all defects and notches on the concrete floor. Beacons are installed before the fill in the form of pin chips.

The dry mixture is diluted with water by recipe and stirred intensively with an electrical mixer. Mix it is necessary quickly and efficiently, as the water binds the mass of the solution is gaining a large number of air bubbles, it becomes sufficiently liquid and fluid. The surface is poured by a self-leveling mixture and quickly resurrected with a special tool in order to maximally remove the main mass of near-surface bubbles.

The solution has a consistency of thick jelly, but hardly hard. The fill with the second layer must be performed with a temporary interval of no more than 10 minutes, otherwise it is not possible to avoid the bundle of the base under the laminate even with a small load.

Self-leveling material is gaining final working strength in two days. At this time, the floor under the future laminate must be closed with a film from drafts and sunlight.

Filing screed for laminate laying

It is possible to align the floor under the installation of a laminate with a roughing floor from OSB or gypsum-fiber plates laid on a layer of clay. The technology allows you to get the aligned floor under the laminate in just one working day.

Initially, it will be necessary to put waterproofing and install the rails of the mounting profile that will serve as lighthouses. The distance between the rails is withstanding within 35-40 cm. The space between the profiles is covered with a clay, leveling the sleeved layer in terms of level. Further, two layers of OSB plates are stacked in such a way that the joints of the layers are separated to the maximum distance. Thus, it turns out a warm and hard floor under the laminate. The joints between the plates are closed with an acrylic putty for a tree and after 3-4 hours are cleaned with sandpaper.

Align the surface under the laying of laminate can also with the help of thick sheets of plywood and wooden lags laid directly on the primed concrete floor. In this case, the distance between lag beams is reduced to 15-20 cm, and each of the lags must be aligned and fixed with the help of screws to the board, packed along the wall perimeter.

Conclusion

The best way to align the floor for mounting the coating of the laminate remains the use of bulk and bulk grounds. In this case, the black floor is obtained light and durable, and the support surface has the ability to redistribute the load, which only increases the durability of the coating of the laminate.

Laying the laminate in residential premises is not a difficult case with which even a novice homemade master can cope with the minimum set of tools. However, if you do not use the recommendations of specialists, then the floor covering will begin to fuse and creak. The reason for this is irregularities on the base floor. Therefore, a reasonable question arises: how to align the floor under laminate with your own hands, so that he served for a long time and did not creak?

Make a smooth base under laminate can be in several ways depending on the type of surface, the degree of worniness and financial capabilities.

Basic requirements for the surface of the base floor

The specificity of the laminate consists in high surface requirements for which it will be treated. Therefore, it is very important before laying a laminated floor covering thoroughly align the base floor. To verify, we need a long construction level or rule and normal level.

The maximum difference in the heights of the prepared base should not exceed one millimeter by 20 square centimeters of the surface or two millimeters by 2 square meters.

If you do not complete the preparatory stage, but simply to wall the substrate and lay the laminate, then in a short time, beautiful floors will stop pleaseing you. There may be several reasons for this:

Due to irregularities, laminate will begin to fake under the weight of man or interior items;
Panel locks will not be able to fully cope with their task, which leads to the appearance of cracks;
Due to the relief in the joints of the panels, moisture will penetrate, which will lead to the bloating of the laminate and the complete deformation of the surface.

That is why it is so important to level the floor under the laminate and follow the rules of laying.

Alignment of concrete floor

In new apartments and homes, most often the concrete draft is unsuitable for direct laying of laminate. And in old houses, the coating has been served for several decades, which led to the destruction of the carrier layer.

Therefore, before you begin the flooring of a new floor covering, you need to decide how to align the concrete floor. You can do it with your own hands, you should only figure out which way it is better to apply to create an ideal and durable plane.

Grinding

Alignment of the base floor with grinding is used under the following conditions:

When there is no possibility to use bulk floors or self-leveling mixtures;
With minor damage and surface drops not exceeding 4 mm.

To process large spaces, it is better to use a special grinding machine. If the area is small, then you can use large sandpaper (graininess 40, 60 or 80) attached to a wooden or plastic bar.

After grinding, the floor must be carefully cleaned from dust. Make it best with the help of an industrial vacuum cleaner.

Be careful, the household vacuum cleaner may not withstand such a load and burn.

2-3 layers of primer are applied to the clean base floor, which strengthens the surface and forms a durable top layer.

If the grinding did not help, and the height differences are too large, then without leveling mixtures do not do.

Partial leveling repair mixtures

This method is suitable for the surface that does not imply a multi-level fill of the floor. For example, with a slight deviation from the requirements or the presence of small defects of the upper layer, which cannot be eliminated by grinding. Repairing self-leveling mixtures are perfectly suitable for eliminating these disadvantages.

To date, there are a large range of solutions for alignment of floors. Each package is equipped with instructions, where it is specified in detail for which surfaces they are better to apply and how to use them. However, that everyone can independently make an ideal surface under laminate, we describe in detail how and with what repair mixtures it is better to work.

Self-leveling bulk floors

Bulk floors are a type of concrete base, to create the so-called self-leveling mixtures. This is an expensive, but very effective way to eliminate baselight defects. This mixture is aligned independently, providing a perfectly smooth surface suitable for laminate mounting.

For the purpose of the mixture are divided into three types:

Self-leveling mixture for coarse alignment. With the help of such a composition, you can eliminate irregularities from 1 to 6 centimeters.
Mixes to eliminate large cracks and chosel. Such a solution is applied only in certain areas. Due to the content of glue, it is easily connected to the rough surface and has high strength.
Finish mixture for final surface alignment. It is used to eliminate small irregularities from 1 to 5 mm. This layer serves as the basis for laying a laminate.

In composition, bulk floors are classified for three types:

Mixes with epoxy or polyurethane resin as a binder. Provide a very durable and non-free surface. Frequently used for surfaces with large loads (trade or industrial premises).
Mixtures on a cement basis. The layer of fill may reach up to 5 centimeters.
The mixture of which includes plaster. It is not recommended to apply indoors with high humidity.

Gypsum and cement bulk floors are used in residential premises. The choice of mixture depends on the humidity of the room and the required coating thickness.

There are fine and thick-filling floors. The combination of such solutions allows to ensure the alignment of the surface in a wide range of thicknesses: from 1 to 60 mm.

Before the fill need:

Delete everything that can weaken the adhesion: dust, spots of oil or glue, etc.
If there are cracks on the surface, they should be smeared with putty;
Progress the floor and give drying for 3 hours.

After that, it is possible to fill the prepared self-leveling mixture. For the preparation of the solution follows:

In the capacity of 50l, fill 5-6 liters of pure water;
Fall asleep 25 kilogram bag mixture;
Place within 3-4 minutes to the consistency of liquid sour cream so that no lumps are left;
Leave for 5 minutes and re-mix. The solution is ready for the fill.

Attention! Exact proportions and instructions for the preparation of the solution, see the packaging of the used dry mixture.

Pouring is made by portions from the far corner of the room towards the exit. The rule is applied to spit. While the liquid solution must be needed with a needle roller to drive air bubbles.

Remember! The bulk floors will dry very quickly, so for large areas, a solution should be prepared in small quantities and immediately use.

After that, the bulk floors leave for solidification. The room should ensure the absence of drafts and direct sunlight. It will be possible to walk on the floor already in 5-6 hours, but laying the laminate is recommended to produce no earlier than 6 days after the fill. If you start working out the flooring earlier, then the not fully weathered moisture can lead to its swelling and damage.

Self-leveling mixtures have a lot of advantages, among other building materials used to create basic floors:

They are easily applied to the surface. Even a person without vocational training can cope with alignment;
The coating quickly freezes, does not crumble and not deformed. On it can be moved in 5-6 hours;
The surface of the floor after alignment is perfectly smooth and smooth.

Based on the characteristics of the mixtures, it can be said that this is a great way to prepare the floor under the laminate. The bulk floors provide an ideal plane that will not deform the laminate for many years.

Screed from concrete

The screed is another way of aligning the concrete floor before laying the laminate. In fact, the screed is a layer of a base floor that is applied to concrete floors or a draft floor. It is made on the basis of cement-sand mix and most often used to eliminate high drops that cannot be adjusted using self-leveling solutions.

For a screed, you can buy ready-made dry mixes or make a mixture yourself based on proportions 1 part of cement on 3 parts of sand.

Attention! The proportions for independent preparation of the mixture depend on the grade of cement and sand grain.

The resulting mixture is poured with water and is stirred to the consistency of thick sour cream.

The bookmark of the finished solution is made as follows:

A dense polyethylene film is wounded onto the floor so that the edges of the walls are slightly higher than the planned level of the screed;
Using the level between the wall and the floor, tags are set;
On the basis of the labels the racks are mounted. These will be guides for further fill;
Concrete is poured between the slats and with the help of the rule stretch the solution along the guides;
2-3 hours after the fill, the surface must be sweat;

If necessary, you can re-grout in a day. The complete drying of concrete occurs after 30 days. During this period, the surface should be regularly watering with water to avoid cracking. With high air temperature, concrete after moisturizing it is necessary to cover with polyethylene.

This method is quite economical, but has several negative points:

Labor complexity;
Long dries;
With incorrect observance of proportions, it may crumble and crack.

Dry screed

The dry tie technique involves alignment of the floor by installing a frame of wooden lighthouses, which are attached to plywood sheets, DSPs or GVL. The space inside is filled with a special backfill.

The procedure for the work is as follows:

A wooden or concrete base is well drying, so that the extra moisture does not get into the dry backfill.
A dense film is spread on the rough surface, to increase the waterproofing of the backfill;
With the help of the construction level, labels of the planned gender are noted on the walls;
The following construction is being built, which will serve as an attachment for covering plates and simultaneously guides for filling. For this, the bars are placed parallel to each other at an equal distance across the room and fastened with dowels or construction plaster to the base base;
The dry mixture is evenly falling asleep and is aligned with the rule on the mounted guides;
The sheets of the selected material are stacked on top of the design and are attached to the wood screws on the tree. The second layer of sheets is stacked so that the joints do not coincide with the first.

Most often, clamzit with different granules size is used as a backfill.

After all the works, it is necessary to predict the surface with a special solution.

This coverage has many advantages:

It does not require a long time to dry out the surface;
Lack of spray, inclination, etc. pollution;
Low load on the overlap of the premises (especially relevant for old private houses);
Good heat and sound insulation;
Low cost of materials and works.

But still, with all the benefits, there is one disadvantage: such floors should not be mounted in rooms with high humidity. Because natural materials in contact with moisture have properties to deform.

It is better to determine how to make the alignment of the concrete floor with your own hands you will help you this video.

Wooden floor alignment

Wooden floors are mostly characteristic of private houses. Unlike concrete, their leveling requires less effort and materials.

If you plan to install a laminate on an old wooden surface, you should prepare the basis as carefully. It is necessary to replace the rotten and broken strips, and the scratched - install in place and secure self-drawers so that they do not hang out.

Schedule the gaps, seams and plotted by putty on a tree;
With minor fluctuations in the level of the surface, it is possible to spend cycular work using a grinding machine (it will remove all cones and bulges);
On the old floor, the sheets of plywood or GBL thick 16-20mm thick in two layers, and so that the sheets of sheets do not coincide.

Below on the video, you can see how to align old wooden floors and lay laminate on them.

Aligning wooden floors for laminate in a new house has a different technique. To create a base floor, wooden floors are filled with heat and sound insulation material. For example, mineral wool. Pre-lags are covered with a vapor insulating membrane. Then the levels of beacons are installed by level, which should provide an ideal horizontal surface.

The final part of the basic floor preparation is the laying of sheets of GVL, OSP or plywood. It is advisable to do this in two layers with overlapping joints where the temperature gaps should be left. Such a base will be able to withstand heavy loads and serves a long time without deformations.

If everything is done correctly and neatly, then under the laminate it will not necessarily be to drain the substrate. The surface will be perfectly smooth, without depression and bulges. The main thing is not to forget to clean it from dust, chips and other garbage, so that the laminate will not creak with time.

However, even on an ideally even base base, we still recommend using the substrate, at least inexpensive and thin. It will add a depreciation effect that it will be positively affected on the tactile perception of the floor, the laminate locks will last for a long time and reduce the load on the joint joints when walking.

As in the old one and in a new house, align the floor under laminate can be a dry screed method that was described above.

By applying any of the methods proposed above, you can achieve an ideal and durable surface on which you can safely drain any floor covering. Now you know how to align the floor for laying a laminate.

Popular floor covering material is laminate. It is easy to assemble and can be installed without attracting specialists, which will save the budget. A wide range of color scheme will satisfy the most refined taste and wishes of the customer. The duration of the service life directly depends on literacy. Laminated boards under the weight of the load and weight of people begged if there are irregularities under it, the moisture can penetrate into the slit, which will lead to the rapid coating wear. Therefore, one of the basic requirements when laying the flooring is a flat and flat surface of the floor, without cracks, pits, roughness, bulges, bends and fesoms.

The need for alignment

Concrete floor under laminate must be perfectly even for the following reasons:

The presence of bulges and depressions on a concrete surface may entail failure of the lock connections. If concrete floors do not align, it will lead to the formation of gaps in the joints and cracking of laminate boards.
The concrete base has a high level of humidity, which is unacceptable for laminate. Excess moisture fall from a screed through cracks in. To exclude it, you should prepare the basis of concrete immediately before laying boards.
Laying of the laminate is impossible at the peashed floor or concrete surface with potholes, irregularities and cracks. This will worsen the quality of laying and entail a considerable consumption of building material. The laminated laminate floor on the deformed base will have a small service life.
Concrete floor alignment can be carried out regardless of the quality of the base and the materials used for erection using CSP, plywood or self-leveling compositions.

Leveling the base level

Before proceeding with the alignment of the concrete surface, it should be cleaned of dust and remnants of the past coverage, remove the dirt and construction trash. Possible cracks, potholes close to cement mortar and the prepared surface is treated with primer, which will improve the adhesion between the materials. The primer compositions reduce the absorption of the solution from concrete, which prevents cracking.

The use of levels will make it possible to make floor alignment quickly and simple. The mass is a dry mix that should be brewed with water. The desired proportions are indicated on the back of the packaging. To make a mixture of a homogeneous structure, it is necessary to mix it with special nozzles for building mixtures. Waters need so much that the consistency reminds thick sour cream, then the laying will be carried out with a layer of a small thickness. When working with the floors, on which there is a bias, you should do a thick mixture. Such a level will allow to align the floor perfectly smoothly. Mix the mixture until all lumps disappear.

Self-leveling mixture

A mixture of self-leveling under laminate can be purchased in a construction store, for cooking you need to dilute the finished dry mixture with water. The proportions are indicated on the back of the packaging. For the manufacture of self-leveling mass you need to pour water into clean ass and gradually pour dry mix into it. Ingredients should be mixed thoroughly, for which they use a drill or a mixer nozzle. Depending on the thickness of the screed make the necessary consistency, pouring the right amount of water. Stir the mass until all lumps disappear and there will be no homogeneous color.

When the self-leveling mixture is ready, proceed to its laying. Start pouring a mixture from a high level of base. The mixture begins to spread on the surface itself. In order for spreading to accelerate, a wide spatula is used, which distribute the solution based on the base. Next, the mixture is aligned using a needle roller. When pouring a self-leveling mixture, a monolithic coating of each poured portions should be ensured. When filling a new part, you need a spatula to connect with the previous portion. The joints of the filled mixtures thoroughly roll out. The process of fill requires speed, in the opposite case, the blend will start drying.

Classification of the self-leveling solution occurs quickly, but to the maximum set of strength will be required for several days.

Monolithic screed

A monolithic screed for laminate is used for large milking heights of a concrete base. Before proceeding with construction work, it is necessary to clean the surface from dust, dirt and construction garbage. Start a monolithic screed from the beacon setting and determining the level of the erected floor. The step between the installed beacons should be observed 60-90 centimeters. The fastening of beacons is carried out on a solution from cement and sand. The beacons can be installed using long screws, for this, holes are made on concrete coating and dowel are driven into them. Next, proceed to the pouring of the concrete solution. To prepare concrete, you will need:

three parts of cement;
one part of the sand;
half of the water.

As a fill, you can use ready-made dry consistencies that are diluted with water in the desired volume. All proportions are shown on the package. A flooded solution should be aligned with the rule and after soaring to remove beacons. Removal of beacons is carried out 24 hours later. The resulting gaps close up with a new solution. After grappling the solution, the surface should be swallowed and cover with a polyethylene film. The layer of polyethylene will protect the flooded surface from cracking, helps to avoid deformations irrigation of laid concrete with water. Concrete floor will reach its maximum strength characteristics a month later.

How is the boarding floor equal? Let's deal with.

Laminate is laid exclusively on a flat surface. Our task is to prepare the floor

Why it is necessary

The floor is equal in order to:

Laminate did not break. The load on the board of the laminate can break it in the case when it is deepening.
Long served castles. When the laminate swell heavily when walking, it means the repeated bends of the clone lock on the connection of the boards. The lock made of MDF is not intended for this and in such conditions it is rapidly destroyed.
Paul did not creak when walking. On the uneven surface of the laminate shifts relative to the base, and the boards themselves will rub each other.

Please note: if under the laminate, a milking floor, he himself can be a source of a screens. The fight against it we will be touched in the relevant section of the article.

What are irregularities

Minor slots or cracks in a concrete base precisely before closeing there is no need. They will not affect it.

DANGER FOR FINAL COATING ORINESS LORY:

Height differences between draft floor boards.
Large potholes and recesses in the concrete floor.
Drops in height between overlap plates.
Paul, filled with concrete layer of variable thickness.

If the behavished boards and are visible to the naked eye, then large irregularities are often not so easy to notice.

How to test the flattering floor before laying a laminate?

How to align the floor

How to align floors under the laminate, depending first of all from the material of the roughing floor.

Concrete

Cement strainer

Large bits of concrete floor are traditionally removed cement - sandy tie. If the slabs of the overlap are laid with a significant difference in the height and you do not want to fit the floor by lagas - there is simply no alternative.

How to perform the screed with your own hands?

Place the temperate rails at the required level. It may be a metal profile, and just a straight bar. The distance between the beacons is around the meter.
Pour the finished solution and the rule align it in the lighthouses.
After two or three days, get lighthouses and, progressing, fill in the recess solution.

The main disadvantage of the method is a long period of waiting before. Concrete will recruit strength within a month. In addition, if you live on the lower floor - waterproofing is necessarily stacked under the concrete. Otherwise, the excess water in the solution will be on the ceiling at the neighbors below.

Useful: if the size of irregularities and drops does not exceed two centimeters, it is easier to pour a self-leveling solution, the so-called bulk sex.

Bulk floor - one of the simple ways to align the surface

Dry screed

How to align concrete floor under laminate without fill with solution?

Dry screed will help.

The floor is covered with waterproofing. As a rule, a conventional polyethylene film.
On the perimeter, the angles are laid out with the edge ribbon. It is suitable with cuts of insole. He will serve as a damper, quenching the sounds between the floor and the walls.
Falling asleep actually dry screed. She, as a rule, serves as a small ceramzite.
Ceramzite is leveled by the Rule of Lighthouses strictly into the horizon.
The usual plasterboard sheet is stacked on top - in two layers, with overlap of seams. Of course, the gender and plywood, and PSE, and chipboard can be stuck with the same success. The main advantage of plasterboard is low price.
Fresh coating along the edge of the top layer seams by self-drawing. Step for drywall - 5 centimeters, more durable materials can be filled with less frequently.

Paul is ready.

The huge dignity of the dry screed is that you do not need to wait until the concrete dry and gain strength. Paul is immediately ready for laying laminate

Finally, concrete with minor irregularities can be aligned quite simply: to put the plywood or OSP to the isolon with a thickness of 2 millimeters without mounting to the floor.

Wood

How to align the floor under the laminate in case it is a boardwalk of lags?

The instruction depends on the size of irregularities.

Minor differences between the boards are compensated by thick tough.

Nuance: Before it laying, be sure to arm the screwdriver and attract the floor boards to the lags by self-drawing with a length of at least 75 millimeters. This operation will help get rid of the screens.

With noticeable drops of the board, again stretched by self-drawing. Further depends on the toolkit available to you.
You can, armed with electrocyclical, align the floor boards. Before it will have to drown all the caps of nails and self-tapping screws at least five millimeters.
Alternative - overlap the floor again plywood or osp. The flooring is attached by self-drawing with a step of 30 centimeters. In each new row, the plywood sheets are stacked with the displacement of transverse seams so that four corners do not converge at one point.

Overlapping plywood irregularity - another simple floor alignment method. Do not forget and in this case, stretch the boards of lags

Finally, if the boards fumbled, went with a screw or rot - the semi-dimensions will not help. The flooring is removed completely. Instead of boards on old lags, if they are in a decent condition, the new floor of plywood or an osp is a thickness of at least 18 millimeters.

Conclusion

Additional information about floor alignment methods can be found in the video at the end of the article. Successes in repair!

Laminate is quite unpretentious and simple in laying coating. Absolutely smooth draft floor will ensure the maximum service life, otherwise the coating will have to be changed after a couple of years. Even in new buildings, the floors have many defects, and if the laminate is steel in the process of overhaul, the flaws made by previous builders are added to the defects of the concrete base.

How smooth should be the floor for laying laminate

The laminate places strict requirements for the black floor, the height difference must be no more than 2 mm per 1 m2, although in practice the laminate is laminated with a difference of up to 3 mm. Almost any sex before laying a laminate to align. Otherwise, with the panel time, it will begin to move relative to each other, the castle connections - break, the floor in the areas of irregularities will be disintegrated into separate panels and starts to deform. The durability of the laminate will certainly depend on its class and quality, so it is necessary to approach the choice very seriously. After all, it is known that the most expensive laminate does not mean that he is the best.

Therefore, before laying a laminate, it is necessary to play floor alignment. This problem is relevant for all residential premises in our country. Newbies The alignment procedure seems very difficult and impracticable on its own. But in fact, any technology to align the floor can be easily mastered. If you approach this process with full responsibility, it is quite realistic to align the floor yourself.

For this, several technologies are used:

plywood alignment;
alignment of a monolithic cement screed;
alignment of levels of levels;
dry screed technology "Superfield Knauf" or similar to it.

Any of the above technologies will give, with the correct execution of all works, the ideal-smooth floor.

Preparation

Before starting, a number of preparatory work should be held:

clear the floor from the construction and other garbage (be sure to use the vacuum cleaner, the brush does not remove dust and small trash particles);
tiled glue or putty close coarse irregularities and cracks;
measure the irregularities of the floor. The easiest way to make it laser level. There is the highest part of the floor and failures. If the elevation is one, it is easier to remove it than bringing the floor to this height;
set beacons, in this capacity you can use guides for drywall, self-tapping screw or mortar. They are installed at a distance of 30 cm from the walls and 60-90 cm from each other throughout the floor area. Their level is evoked with laser level.

Align the floor alone is very difficult, especially when it comes to bulk floors. Therefore, you will need 1-2 assistants (more - no sense).

Alignment plywood on lags

This method has proven itself to equalize the floors without dismantling the old wooden coating, but is often used in other cases. If the level drop is less than 2 cm, then the lags for leveling can not be applied, the plywood is attached to the draft coating, and the laminate can be laid on it.

For alignment, you will need plywood - enough sheets to overlap the floor area twice, lags - wooden unstored boards 2 or 3 grade wood of coniferous or hardwood wood (except linden and poplar). The thickness of the lag should be at least 40 mm, the width is 80-100 mm. Lags are attached to a concrete or other base with special sheets with a pitch of 400-500 mm. In the residential premises, lagows are stacked across the falling lights. They form the level of the rough floor, the height is selected depending on the level drop.

For each lag in several places, small wooden bars are stacked throughout the length, they, in turn, rest on the rubberoid or linoleum pieces, it allows you to create a flat floor plane.

The lags adjusted in the height are laid out in two layers of plywood sheets. Between lags, it is possible to lay heat and sound insulation - this is a significant plus of this method. Plywood is fixed on lags by self-drawing with a step of 5-10 cm, additionally, the joints are sampled by PVA glue. The second layer is placed perpendicular to the first or with a displacement. After the installation is completed, small gaps between sheets need to sharpen.

Before laying, all wooden black floor elements must be processed by antiseptic composition.

Alignment of cement screed or level

These are two similar on the principle of the method, only the bulk floors are at times more expensive than the usual solution. But the monolithic screed of the cement mortar dries long and quickly destroys, therefore it is used less and less. Filling technology is extremely simple: the beacons are set, on them - guides, the prepared solution is flooded between them, it is aligned with the rule (board or special rail, which moves along the guides).

After 24 hours of waiting, while the screed dries, beacons and guides are removed, the holes are closed with fresh solution. The surface is wiping, finally aligned, closes with a film that prevents the cracking of the screed. After about 28 days, the floor coating can be laid.

Bulk floors are more perfect and fast in obtaining a final result technology. With a large drop of heights, its use will be expensive to you, but on the quality of the floor, if possible, do not save.

It should be noted that on many levels of levels is an attractive "self-leveling", but this quality is inherent only by expensive mixtures (Waaterli Plus, Finnish production, about 600 rubles per bag of 25 kg, or other mixtures of the same price level). Most inexpensive mixtures need to be aligned manually.

To align the floor level, you will also need a rule, a spatula and roller with needles. Also, it will not be superfluous to take care of the shoes: Professionals use shoes with sharp spikes - it does not leave traces when walking through the unrexious floor. The working fluidity of the mass is lost 15-20 minutes after pouroned, therefore it is necessary to spit it out if the level marked by the beacons. Optimally, when two people prepare a mixture, and one is engaged at this time.

In a private house, it is best to make heat and vapor barrier to the floor before aligning the floor, it will significantly increase the service life of the laminate, protect it from the temperature drop and dampness.

Start work is better from the morning, the fill is carried out without breaks, so before you start, you must have the entire necessary mixture with a margin. To mix the mixture, you will need a mixer with a long wedge, getting to the bottom of the container, and a capacity of 30-40 liters. The proportions should be exactly what are indicated in the instructions, otherwise the floor will be loose and fragile.

The floor is poured as large as possible, next to each other, then stretches through the room with a large gear spatula and spacked with a gear roller. The solution released behind the doorway is better in the frozen state to trim the spatula, do not make any thresholds.

The day after the fill on the floor can already be walking. But it is not worth doing this - let the mixture dry for 5 to 7 days. Only then the surface will be ideal for laminate mounting.

Leveling dry tie

It is also not cheap (from 270 rubles per sheet and 180 - per bag of backfill 30 kg), but a fairly simple method of alignment. The superflake sheets are stacked by a layer of claymps distributed across the floor. The technology is not distinguished by complexity, the only subtle moment is the laying of the first sheet, it is produced from a temporary area of \u200b\u200babout 50 × 50, laid on the clay.

Before laying a ceramzite to the floor, a vapor-insulating film with pouring on the walls 10-15 cm. On the perimeter, the edge ribbon is laid in a width of no less than the height of the dry screed. The KNAUF instructions indicate that the ceramzite falls asleep completely to the entire room, but experienced builders recommend putting sheets by plots, falling asleep on the island between the guides at a time. So there will be less dirt, the ceramzite will not fall into the joints between the sheets, and it is much easier to align it.

The sheets are fasten with each other with special glue and self-drawing (in 10-15 cm increments). On sheets that are adjacent to the walls should be cut out of Falts so that the wall has a double layer of material. After fixing alignment, you can lay a substrate under the laminate. Environmental can be considered a cork substrate, it is hygroscopic, does not emit harmful substances, it does not die over time and has good noise insulation. As well as the substrate you can align small floor irregularities.

Before aligning, check out the instructions for the selected material and stock all necessary to start work. For some technologies, breaks in the styling process are unacceptable, so minimal reserve should be provided. Under all the rules of laying the coating, you can even make a perfectly smooth floor, which will be a good base for laminate.
