How and how to align the concrete floor in the apartment with your own hands. How to align the floor in the presence of serious and easy defects: cyclishing, laying of plywood, bulk gender is the fastest method of alignment of floors

It is equally relevant for apartment owners in old houses, and for the inhabitants of new buildings. The first is looking for an answer because the basic coating in their residential premises is in a deplorable state due to the already large operational periods (yes, perhaps, it never was good, even during the years of her "youth"), but the second you need to know this The reason that, despite the application of new technologies, the quality of the finish even in the newly donated buildings is still far from the ideal. While modern flooring requires sometimes almost smooth surface. How to create acceptable conditions for them? What to do? How to align the concrete floor and how best to do it? You will find all these questions in our review.

We estimate the existing surface and choose a new floor covering

It is worth noting that the alignment procedure can sometimes be quite expensive and quite long. That is why, in order to reduce material and temporary expenses, you need to be able to correctly assess the situation. That is, carefully inspect the reason and decide which floor covering will be applied. As for the first. The base surface may be different. Sometimes it is in full of decent state with the exception of some places covered by cracks. Or there are only small protrusions and depressions. In such cases, you can do with low blood, by overgrowing the floor locally, as they say, according to the testimony. If there are significant defects on the base coating, as well as huge height differences, it will be necessary, naturally, roving from the angle to the angle. Now it concerns finishing materials. Some floor coverings are very demanding to the base. Take the same laminate. Even a minor difference in some five millimeters is able to reduce all work on finishing. Laminate laminated on this basis can simply be simply deformed and crap on the seams. While the linoleum is not terrible defects. So it is from the choice of the finishing floor covering and directly the very state of the basic base and must be repelled, staying in search of a response to the question of how and how to align the concrete floor.

Obvious options that require elimination

So, what concrete floor is subject to alignment? To put in order must necessarily have a foundation having:

• Roughness, chips, various cracks.
• All sorts of protrusions or pit, which are noticeable with visual inspection.
• SCOS or drops in height.

Depending on the existing defects, choose a method of alignment and the material necessary for work.

Types of alignment

If the floor does not have special drops in height, but has some defects of the type of cracks, they are close using their own composition or epoxy concrete, while conducting some prerequisites for the preparation of the base. Local protrusions and pits close up in the same way. Height differences are eliminated by dry screed, alignment on lighthouses or by bulk composition.

Get rid of cracks

Such defects may appear both on the old basis and on the recently filled, if the steps or requirements of the technological process were violated. Therefore, know how to get rid of cracks on the concrete floor, you need to each master. So, it's impossible to smell them from above. First, you need to carefully catch the entire surface of the crack, and a very peculiar way - it is necessary to cut the chisel to the defect with the help of a hammer as deeply as possible. Thanks to this procedure, first, you will be able to detect hidden chip defects, and secondly, create the desired gap for the mixture. After the preparatory work is carried out, you need to diligently remove all pieces of concrete, clean the cavities from dirt and dust, pour water. After drying, the entire surface must be projected. Perfect for these purposes the composition Grund. After that, you need to mix with water cement M400 brand. The solution must have a consistency of liquid sour cream. And then you should add liquid glass or PVA glue. The amount of additional ingredient should be equal to the volume of the prepared mixture. Then you need to pour cracks with the resulting solution, wait for drying and sticking the surface. Very small cracks can not be expanded, but simply close them with tiled glue of any brand, pre-forgetting to trust.

Close up of pits

If the floor surface is quite smooth, then the screed is not fully needed. Just just get rid of pits. For this, their walls and bottom need to be treated with a grinder to remove chips and fragile layers. After that, the pit should be cleaned from pieces of concrete, dirt and dust, pour water, after drying to progress. On the bottom you need to pour a dry small-piece crushed stone with a rather thin layer, and then close the defect with epoxy concrete. The domestic composition "Glain" is perfect for these purposes. I pour them to a pit so that the solution does not reach the top of the centimeter for two. After drying (approximately an hour), we compare the surface with a special putty on concrete. Experts recommend paying attention to the brand "Elac-ED".

As for the buggers, they are enough to sile with a grinding machine, clean, harvest, and then align the surface with the help of the same "elacra".

Dry screed

How and how can the concrete floor can be aligned if there is little time at the disposal and do not really want to mess with solutions? Make a dry tie. This procedure is quite simple, so practically any domestic master can cope with it. The principle is next. The base base is thoroughly cleaned from dirt and dust. Then the waterproof film is laid on it (you can use the usual thick polyethylene). Then over the entire surface layer with a thickness of five centimeters, a dry leveling mixture is poured. It can be made of crumbs, granulate, the sand of quartz or even polystyrene foam. And on top already laid on the lags and fasten with self-stakes or Phaneru, or Fiberboard sheets, or moisture-resistant plasterboard. But it is best to use special sheet material for these purposes called "Super Poll". After a dry screed, you can almost immediately lay the finish flooring. It is the home masters that experts recommend primarily considering this method, since it is possible to align the concrete floor with their own hands with this method without any problems.

Screed in lighthouses

Since it is sometimes impossible to align the floor with the help of less costly methods, it will have to consider such a way as the fill of the new floor using lighthouses. As for the financial side of the issue, it is not so terrible, but the procedure will require significant costs. In addition, in this case you need to have at least minimal skills of working with lighthouses and cement mortar. What should be done? First of all, clean and rebuilt the base. Then to mark the markup, it is desirable using a laser level, and pull between the walls in the direction from the window to the door of the thread orientation for the beacons. And then, to install perforated guides on them on the floor, using cement (plaster) mortar. The step between each lighthouse should not be more than one meter. After that, it is necessary to prepare the M400 cement solution (the amount of water will be indicated on the package), pour it between the installed profiles and align the rule, moving backwards from the window to the door. Such a screed dries sufficiently long, in addition, the first three days it must be made with water. However, this method is quite budget and allows you to get a really smooth and durable coating. Therefore, if you have a sufficient number of time and do not know, for example, how to align the concrete floor under the laminate, take it into service this method.

As for the beacons, some masters remain them inside. However, experts recommend still to get a profile, and emptiness is chopped with tile glue. It is perfect for these purposes budget, but because the luxury is no less durable.

Self-leveling floor

If the height difference is no more than five centimeters, and there are free funds available, the leveling mixture for concrete floor is perfect for the arrangement of the base surface. She is quite expensive, but it's easy to work with it, in addition, the alignment procedure does not take much time. As for technology, it is necessary to start, as always, with preparation. The basic base is required to clean and primed. Then you need to mark up the laser level, drawing on the walls of the line for which the upper borders of the new floor will be held. After that, it is required to mix the solution according to the instructions placed on the package. The best mixes for alignment, according to experts, these are selfiethlers Ceresit CN 69 and Ceresit CN 68, Vetonit 3000, EK FT03 FINISH. Many masters praise and more budgetary domestic mixtures produced under the brand "prospectors. So, the alignment is starting from a long angle, pouring the solution to the floor and aligning the coating (according to the marked marks) first by the rule, and after a special roller with needles.

How to align concrete floor under laminate

Laminate is, perhaps, the most capricious floor covering, which requires almost perfectly even grounds. What is better to align the concrete floor under it? By and large, in this case, any of the three methods described above will suit. However, there is another option. You can try to align the concrete floor of the plywood. Unlike the same tile, laminate when laying does not require the use of the solution, so that the presence of wooden sheets under this coating will not affect the quality of the base base. And the alignment method itself is quite simple and fast. The concrete base is cleaned of dirt, it is ground, after which the sheets of plywood moisture resistant (thicknesses in 10 mm will be sufficient), and in the same principle, as well as laminate (so that the seams of the elements did not coincide, but were in a checker order) . After that, another layer is laid, but so that his joints do not coincide with those of the lower layer. This plywood is already attached to the lower sheets of self-draws. After laying, you need to walk along the seams with a grinding machine for the purpose of final alignment of the draft floor.

A few words about the loggia

On loggia you can also apply all the methods described above. However, quite attractive many experts consider the alignment in this concrete floor with the help of the same plywood, but on the lags. What do they determine their choice? By the fact that thanks to this method, you can additionally insulate the floor of the loggia, having paved between the lags the corresponding material. Say, foam, mineral wool. Or a professional, but more expensive insulation Tekhnonikol.

... about the garage

It is quite clear that in this room no one places laminate or parquet. The floor here usually makes concrete. Basic requirements for the foundation - so that it is even. And, of course, durable. How to align best to do and then cover it with a special layer of the hardensier - the so-called topping, which will protect the surface from destruction. Caparol-Disbon, Neodur (Korodur), MasterTop (BASF) and Domestic "Herculite" and Reflorine are considered the best compositions.

... and about ceramics

If it is planned to lay ceramic tiles to concrete and the base itself is not particularly curved, you can align the floor in the process by adding a greater or smaller amount of tile glue under level control. True, this method is applicable only if the differences are not more than three centimeters. In addition, if you decide to resort to this method, you need to buy only high-quality, with improved characteristics, for example, intended for ideally suitable for these purposes "Ceresit".

Conclusion

We tried to tell enough about how and the better to align the concrete floor in one way or another. In addition, they also affected the issues of alignment technology, named the brands of the best materials used in this type of work. We hope now you can easily choose the appropriate option for your specific case. After all, you already know no worse than any professional, how and how to align the concrete floor.

One of the priorities when conducting overhaul in the apartment is the alignment of floors. This is especially true of housing in the houses of the old building, which was purchased in the secondary real estate market. The situation is typical when the slabs of the overlap not only have differentials within the same room, but are at different levels in the adjacent rooms. To align the floors in the entire apartment in one horizontal plane under the flooring of linoleum, laminate and other modern outdoor materials, there are several technologies, most of which, after studying the nuances, are quite performed with their own hands. What is the method of alignment of the floor to choose in a particular case, focusing on the complexity of the process, and how much it costs, understand by reading the article.

How to measure the floor level?

The method of alignment of the floor surface directly depends on the degree of its irregularity. It is impossible to notice the unarmed look at irregularities and the more clearly note the level of future coverage, for this you need to use special measuring instruments:

• Water linear level. This is an ordinary bubble level of not a long line in the form of a line. In order to measure irregularities on large areas, a construction rule or a flat rack of the desired length is used, to which the level is placed. This method of measurement has large errors in large areas, it is used to measure irregularities on the area to 2 square meters.
• HydroWore. This is a device in the form of a transparent hose filled with water and having two brackets with traffic jams at the ends. Such a device allows you to accurately mark the horizon around the perimeter of the room and make the marks on the walls. It cannot measure irregularities on the plane.
• Laser level. This is a modern and accurate tool, as easy to use. The device issues laser rays in several planes. It is enough to install it in the center of the room, and it will designate the level around the perimeter with a maximum error of 1 mm.
• Level. This is a high-precision optical device that allows you to calculate the difference between two specified points on the conditional plane. Such levels are used in large-scale construction to work with huge areas.

To work within one room, it is enough to apply a laser level. If it is necessary to derive a single floor level in several rooms, the hydroelectric system with the desired hose length is used.

Swing, crookedly standing furniture, bouncing washing machine - all this consequences of unevenly laid gender. Its alignment should be the most first procedure when repairing.

Wooden base alignment

The order of work on the replacement of the wooden floor is as follows:
1. Using scrap and ax, plinths and old flooring are removed. All construction trash located under the floor is removed. Before the flooring of new floors, it is necessary to close with cement mortar cracks and cracks in a concrete tie.

Old rotten floors are deleted

2. Running old lagi (wooden beams with a cross section from 110 mm used as a base for flooring) and destroyed from time floor boards are ejected.

3. To replace the lag selected rectangular. At the same time, the height of the lag should be more than 1.5 times their width. The size of the sections of the bars depends on the width of the room in which they will be installed.

Calculation of the section Lag.

4. Before laying, the lags should be treated with antiseptic and waterproofing: olife or bitumen. Cheaper option will be impregnated exhausted machine oil.

5. The tree absorbs moisture very quickly, so it should not install lags directly on the concrete. They are placed on layer of waterproofing (Ruberoid, film or bitumen mastic).

6. To ensure ventilation, lags should fit at a distance from 5 cm Before concrete or overlap beams. Bricks or wooden bars are used as linings for lags.

Lag on bricks

Laying the lag on the brucks from the tree

Important! So that the lags did not absorb moisture from the walls, between them and the wall necessarily the gap of 2-3 cm.

7. If necessary, a layer is paved between lags heat or sound insulation. The foam or polystyrene foam is excellent thermal insulators, but they will not protect them from the penetration of foreign sounds in the apartment. It is better to use Minvatu as a sound insulation material.

Logging between lags of mineral wool

8. To put lags perfectly smoothly, along the walls on a water or laser level are applied. horizontal marking.

Marking on the walls

9. When laid out, lag should also control their location. construction level. If necessary, lags are inspited to the necessary height. Pauses can also be corrected wood linings or fiberboard. To protect against their displacement during the operation of the floor, they will be attached to the base.

10. Fire boards are used as a rough floor. Their thickness depends on the distance between the lags.

Selection of genital boards

11. When laying a genital speech, the horizontal of their location is also selected by the level.

Important! Do not purchase unreasonable material. Humidity of boardcooked for flooring should be 12%. The overpowering rack can crack, and the wet will gradually dry, and the gap will appear in the floor.

Alignment of concrete tie

The bulk mixtures are quite expensive material, so they are used only for aligning small drops. With a significant difference in the height of the floors, a concrete screed is used.

1. If there is in the old screed large influx They are removed with a jackhammer or a sledgehammer. If you leave them, the floor will have to raise the height equal to the height of the influx.

2. Before the start of the fill of the new layer, the old floors are purified from dust and garbage. In order for moisture from the solution to be absorbed into the floor, in front of the layer, the screeds are packed: a plastic film or rubberoid, which are placed with a small adhesive on the walls. If the waterproofing is not provided, you can moisten the old concrete with a small amount of water.

Waterproofing concrete tie

3. To obtain a smooth horizontal surface, the floors are aligned by mayakov: Metal profiles decomposed on the floor strictly horizontally. They are placed on " brands"(Fluttering a thick solution). The height of the imposition of "brands" is regulated by the level.

Mailout of Mayakov

4. Since the solven leveling is made by a special tool - construction rule- The distance between two lighthouses (guides) should be equal to its length. (The rule is a solid 1-3-meter metal strip, narrowed along the entire length).

Leveling for lighthouses by rule

5. To strengthen the screed when overlapping a too large solution of the solution, it is reinforced metal mesh.

Alignment of bulk mixtures

For black alignment, the floor will need a liquid mixture made on the basis of cement. A gypsum mixture that can absorb moisture is used mainly under the installation of parquet. Expensive semi-round or colored polymer solutions ("Liquid linoleum") is used as a finishing finish and fill only on a pre-aligned surface.

Blend for black floor alignment

1. Technology of applying a liquid mixture of any composition is about the same. "Liquid" floors are poured only on a carefully prepared surface, purified from garbage and processed primer Deep penetration. They can be put on concrete slabs or cement screed. Pouring the mixture on wooden floors or ceramic tiles is allowed.

Floor treatment primer

2. With an excess or lack of water, the distribution of the mixture over the surface will be uneven, so it should be accurately observed dilution proportionsspecified by the manufacturer on the package. Stir the solution should be as close as possible until the lumps are completely dissolved. For these purposes, it is more convenient to use a drill with a nozzle or a building mixer.

Solution should be thoroughly strained

3. Permissible temperature In the room where the mixture will be used is indicated by the manufacturer.

4. The mixture is started to fill from the longest walls located opposite the entrance. In order for no height drops, its laying should be continuous.

Fill mix

5. For uniform distribution of bulk floors use wide spatula or rule, raised on the handle. In order to remove air bubbles, the solution is additionally processed needle roller.

Speaching of bulk floors

Needle roller processing

Important! Roller processing and floating floors must be made before setting the solution. Otherwise, the drying mixture is swinging.

6. Drying time of bulk mixtures - 2-3 days. In order for the floors evenly, in the room there should be no too large temperature differences and drafts.

In most cases, the apartment repair does not cost without alignment of surfaces, and in order to quickly and inexpensively make rough preparations or make repair of floors, self-leveling mixtures can be used. There is a large assortment of dry mixtures, they are on plaster and cement basis.

Screeds are performed quickly and qualitatively, provided that they perform a qualified master, because Alone to make them hard. In order not to make mistakes in self-fill, order repair wizard services with us - then you are guaranteed to get a smooth and beautiful screed

Often, the need for floor alignment appears after dismantling the old floors, which are already impractical.

Floors of the sexes and ways to align them

Alignment of the self-leveling mixture is possible when the floor drop is not more than 20 mm. In some cases, during a drop, let's say, from 30 mm you can also use the bulk sex, but only with the placement for the floor. If the difference reaches more than 50 mm, it is advisable to use the CNAUF screed so as not to load the slab overlap and do not wait for drying if it does not have time.

Sometimes the dry screed refuses, and it remains only to use a wet tie of the floor with a clay. Thanks to the addition of a large fraction of a large fraction in such a tie, you can save on dry mixtures and also not load the slab overlap (but this method is more often used in the bathrooms or when there is time to wait for the floor).

Before the fill, the surface is important to treat thoroughly.

The base is cleaned of garbage, close the gaps, soaked. After the soil is finally absorbed into the surface, the wizard pours the solution and distributes it, eliminating air bubbles with special tools. If the area is large, the distinction is exhibited and the fill occurs in two stages.

The technology of bulk floors will ensure the drying of the surface to a solid state after 3, 4 hours, and complete drying takes up to 3 sides, after which it is possible to start laying a laminate or any other flooring.

Dry mixes for alignment

To equalize the floor, many different materials are used, depending on the degree of maintenance of repair. For the fill in the apartment, mixtures for internal works of such manufacturers are usually used as: Ilsyl, prospectors, which will be found, Unice. To align the high drops, it is preferable to use Peskobeton M300 or use the dry floor of the KNAUF.

With each mixture you need to be able to work, because Each material has its own determined solution to the solution. Floor mixes have speed drying and durability. The surface is obtained smooth, smooth and after complete drying to it, various types of flooring can be stacked.

If the thickness of the screed is greater than 2 cm, mixtures on a cement basis are used. Here the most common mixtures for floor alignment is: the bulk floor is "thick", sandbetone M 300 different brands, standard stroke, fort.

The cement-sand mixture and sandbeton differs in price, quality and strength. Under the laminate, parquet board, linoleum and carpet, you can use sandbetone or dry mixtures for the floor with cheaper, and when you tie under the fan, parquet, array and tile, the mixture is better to choose more expensive, because This material is glued to the screed, so it should be more durable by its structure. If the surface has already ever been left, then before laying a laminate or parquet, it is better to check the base on evenness and to align. Such alignment can be partial if the screed does not bother, of course.

Floor alignment in Moscow Price per m2 of work

The cost of equalization depends on the complex and the complexity of the work performed.

The most affordable way is the alignment of the floor by self-leveling mixture price per square meter of operation M2 which is 250 rubles. With minimal safety irregularities, the minimum amount of materials is used.

With significant floor irregularities or, if electrical wires and heating pipes are carried out, it is necessary to make a cement-sand tie for lighthouses. Prices for floor alignment with light rooms are higher than on the alignment of the self-leveling mixture, because The process of work is more time-consuming and more materials are used (screed on the lighthouses 500 rubles per m 2). Also, with a large screed thickness (above 5 cm), clamzite can be used to reduce the price of building materials as a filler. Such a floor is gaining strength and completely dries over 3 - 4 weeks and is more suitable if other types of work are made in the apartment or room.

But it happens that there is no other construction work in an apartment or room, but the floor must be aligned in a short time. In such cases, the supply of a dry tie technology is in demand (the price for the work of 400 rubles per m 2). Prices for the materials for a dry screed may differ, because There was a large range of clayflows and, accordingly, the price of it is also different.

But this method of alignment definitely has an advantage over other ways to align the floor, because Dry screed is ready for laying outdoor coatings after installation.

How to align the floor under floor coverings

If you decide to put a laminate or parquet board on your floor, then you must first check the base for strength and evenness. The allowable deviation in the level should not exceed 2-5 mm for two meters, and if the difference is greater, the floor alignment will be required.

Align the floor under installation in the following ways:

• Fill of the bulk gender;
• Cement Sand Floor Screed;
• Dry tie of the floor Knauf;
• Installation of plywood on lags.

Smooth floor in any room is needed not only from aesthetic motivations, but also warns the injury to the property owner. An unpleasant view of the sounding cabinet is not compared with the tilting of the swinging TV or the fracture of the limbs as a result of falling on the "almost even place." Whatever the cause: initial errors in the construction or appearance of chosel and cracks during operation, is the question "how to align the floor?" Sooner or later, it stands up and before the newcomers, and during repair.

In modern housekeeping the basis of the floor in the house, apartment, garage, the office is concrete or concrete slabs. Depending on the purpose of the room, the linoleum, ceramic or PVC tiles, parquet, laminate, carpet, and the durability of external, and often expensive coating depends on the fattening of the concrete base of the floor.

To obtain an even durable base under the finishing floor covering, the achievement of heat and hydro and noise insulation is carried out either by a screed method or applying solutions of special mixtures to align the floor.

The choice of method of alignment depends on the size of the height of the floor height and the material of the first floor: with the difference in the floor level of 3-4 cm, the aligning screed of the concrete floor is performed; If the floor is generally smooth, but a large amount of crack is detected, then the alignment of self-arguing mixtures or tiled glue.
Specialists distinguish between several types of screed, based on two main methods of styling: dry screed and screed with adding various liquids.

Dry screed is easily performed by even a novice builder, it costs cheaper and significantly insulates the room. Ceramzit, dry quartz sand, expanded polystyrene foaming as filler. Obillion fuel-resistant sheets (GWL) or wood plates (chipboard, dvp), so the dry screed is made more often in residential rooms.

The purified floor is impregnated with a primer solution that reins concrete and increases its waterproofing properties. You can use "Betonacton". After drying, the layer of polyethylene (more than 50 microns) of the film is placed, joking a 18-20 cm panels and glueing them with scotch. The walls are left by 12-15 cm and are sampled by damping tape.

In the absence of the necessary experience, it is advisable to put on the edges of the P-shaped profiles turned upward on the floor to the floor, establishing them by level. Fall asleep part of the filler into the formed cells, align it with the rule and put the sheets of the future floor, sinking the joints of the GWL glue PVA and tightening with self-draws after 18-20 cm.

At the walls, the edge of the gypsum fiber sheets is cut. It is not worth paying attention to the seeming instability of the first sheets, when they are splicing them into a single monolith, a solid warm floor is obtained.

Thinking up, the better to align the floor, the majority leans to the classic variant of the cement-sand screed, which gives a strong smooth base for the finishing floor layer. The thickness of the future screed should be at least 3 cm, otherwise the strength is reduced at times.

The concrete base is also purified, ground and dried. With the help of a regular, water or laser level, lighthouses are installed using a laser level, you can install lighthouses without helpers. Lighthouses mainly put durable metal racks or T-shaped profiles, but you can use pipes, cutting board or timber.

Rakes are installed on a thick solution, at a distance of no more than meter from each other. The solution must be frozen, otherwise, when aligning the screed, you can move the lighthouses and all work will go to the pump.

Subsequent work requires no experience, but patience: pouring the solution consistently from a long angle, the floor is thoroughly aligned with the rule, moving it not only along the rivers, but also by making movements around the circle. In this case, the solution moves to the right and left, compacting and filling the voids.

For the preparation of the solution, the M500 grade cement is most often used, adding three parts of the sifted sand and water to one part (about 1 liter per 1 kg of cement). You can also apply ready-made leveling mixtures for the floor commercially available: M150, M200, M400. The greater the number in the name of the mixture, the stronger the resulting coating. Prepare solutions in accordance with the instruction available on the bag.

For the next day after laying the day, the screed must be slightly moistened with a roller, on the second day it is repeatedly moistened and check the strength of the solution. If you can already go on it, the lighthouses are cautiously pulled out and all formed emptiness rubbing the fresh solution.

The screed is covered with polyethylene film and, periodically moistened over the next week, withstand up to hardening at least 2 weeks, and better - month.

Along with the strength and relative cheap, aligning floor screed takes a lot of time, which is deprived of modern self-leveling mixtures, which are often called bulk floors or leveling mixtures. The upper coating can be installed after 10-12 hours, and completely bulk sex acquires its characteristics within 12-14 days.

It is possible to use such mixtures with no more than 3 cm heights, focusing on the instructions attached to bags with mixtures, since the further coating strength is more dependent on the chemical filler of the mixture. Deep (more than 6mm) cracks and recesses must be pre-embedded with a solution and dry.

On the purified and projected concrete, the smooth mixture is poured into the instructions and smash its metal spatula. After that, rolling the bulk floor with a needle roller, removing the smallest air bubbles that reduce the strength of the floor.

You need to perform the work together, as the mixture is seized in about 10 minutes. If necessary, slow down the sinking speed, the floor is pre-slightly wetted with cold water, which also avoids the cracking of the bulk floors.

The small thickness of the finished floor allows it to be widely used in low ceilings. Along with high cost, the negative characteristics of self-leveling mixtures include fragility and weak resistance to low temperatures of epoxy mixtures can be attributed; mixtures based on polyuretes of unstable to chemical exposure; Methyl methacryls are weakly resistant to abrasives.

Sometimes small cracks or irregularities are found in the floor, in this case you can align the floor with tiled glue, given that, for example, "Cerezite" can crack already with a thickness of 3 mm. Apply complete floor alignment with tiled glue, replacing them with a bulk sex, it is undesirable, despite the low cost of glue.

By deciding for themselves, how or what mixture to align the floor, it is necessary to take into account the temperature and humidity of the room, the height level drop and the slope of the concrete base, the alleged loads during the operation of the floor, labor and financial costs.
