Modern floor coverings such as laminate, parquet or porcelain tiles require a perfectly flat subfloor for installation. To achieve this, various types of screeds are used - from wet to semi-dry and dry. The technology of dry screed base floors has been known in construction for a long time and was patented more than 40 years ago. In the last decade, it has become especially popular thanks to the emergence of the "super floor" system, which allows to carry out works with high speed and guaranteed quality.

What it is?

For more than a hundred years, the foundations of the floors have been leveled using the classic cement-sand, or, as it is also called, concrete screed. This technology and today consistently provides a solid and level base for the installation of various floor coverings, from parquet to carpet.

Image
Image
Image
Image
Image
Image

However, the device of a concrete screed is not possible in all buildings, it is especially doubtful to carry out work using this technology in houses with wooden floors.

In this regard, a version of dry floor screed was developed, which has cardinal differences and is more like creating a "puff cake" on the surface of the sub floor than the usual screed. Dry screed floors, prefabricated floors, dry screed, floating floors - all these are synonyms denoting a similar technological process, namely, leveling of floor bases with a waterless method.

Image
Image

Dry floor screed is usually carried out with various fill bases, but the most professional is a dry screed using Knauf dry mix.

This method focuses on the correct laying of materials, which ensures a perfectly flat and solid surface. There are several methods for arranging a dry screed. The most famous are the methods developed by the German manufacturer Knauf, of which there are 4 varieties:

  • Sheets of gypsum fiber "super floor" are laid on fairly even floor slabs. This is the easiest and cheapest way to increase the strength of the subfloor.
  • A layer of sound-insulating material is laid on the ceiling, which is covered with double sheets of gypsum fiber board. This method contributes to sound insulation and a decrease in heat transfer.
Image
Image
Image
Image
  • At the base there is a vapor barrier film, on top of which a dense material is poured that can be evenly distributed over any surface. Usually it is fine-grained expanded clay, the size of which does not exceed 5 mm. Superpol GVL sheets are laid on top. The surface is leveled in a similar way.
  • Expanded clay is distributed on the vapor barrier film, which is covered first with a waterproofing layer, and then with a soundproofing layer. The surface is fixed with double sheets of gypsum fiber. Thanks to this method, the surface is leveled, the floor is insulated and soundproofed.
Image
Image
Image
Image

The second most popular is the method of creating a "floating floor" from the Rockwool company, which is more suitable for warming the base and providing acoustic insulation, but does not provide equalization of height differences:

  • Insulating stone wool Rockwool "Flor Butts" is laid on the surface of the base.
  • On top of the insulation, two layers of thick plywood are applied, the seams on which must overlap.
  • Instead of plywood, you can use two layers of large GVL sheets, also overlapping each other.
  • You can also lay OSB sheets as a base.
Image
Image
Image
Image

The amount of volume that a dry screed occupies can vary significantly depending on the initial fluctuations in the level of the base and the number of levels to be laid. The minimum necessary is the distribution of the dry mix with a layer of 20 mm; the builders consider the height of 70 mm to be the most acceptable for subsequent operation. Therefore, when using a dry screed, the height of the room is necessarily reduced and differences in the height of the floors appear with those rooms in which this procedure was not carried out.

Image
Image
Image
Image

Therefore, builders recommend the use of this dry screed method for the entire apartment as a whole, in order to maintain the integrity of the perception of the interior.

Features of the

There is a lot of controversy on construction forums about the specifics of carrying out work on a dry screed in an apartment. Basically, various options for non-professional editing are discussed, nullifying the efforts to acquire materials. Also, quite often you can find messages about attempts to save on components, which ultimately lead to disastrous results.

Image
Image
Image
Image

Therefore, when considering the positive and negative aspects of the dry screed procedure, first of all, you should pay attention to the observance of the laying technology. Site visitors offer, as a guarantee against the unprofessionalism of the craftsmen, to contact construction firms with significant experience and a proven reputation. Also an important point is the purchase of original branded materials.

Image
Image

Advantages of a properly executed dry screed:

  • Execution of work in the shortest possible time: two specialists can perform work in a medium-sized room during a working day.
  • Leveling out any surface differences.
  • Possibility to install floor coverings immediately after finishing work on dry screed.
  • Noise insulation and thermal insulation of the room.
Image
Image
  • Lack of "wet" work processes, as no concrete mixing is required to level the floor.
  • Significantly lower weight of materials, which allows you to level the floors in buildings with wooden floors or on a balcony or loggia in the "Khrushchev".
  • Uniform subsidence of dry floors during shrinkage due to the absence of fixed beacons.
  • The ability to provide easy dismantling of the dry floor, as well as quick access to structures placed inside it.
Image

Image

Image

Opponents of installing a dry screed give, basically, one argument that turns out to be very significant for residents of multi-storey buildings. This is the susceptibility of dry floors to moisture, in particular to flooding, from which none of the tenants of a high-rise building is immune.

Image
Image
Image
Image

Indeed, expanded clay, which is the basis for creating a dry floor, has a high hygroscopicity and quickly absorbs moisture. Since at the base of the dry screed, as required by the laying technology, there is a vapor barrier material, moisture that gets on the expanded clay, usually along the walls from the neighbors from above, does not have the ability to flow down and lingers in the bulk layer, causing soaking of the gypsum fiber board and floor covering laid on its surface …

Image
Image

The only solution to this problem, professionals call the dismantling of the flooring and gypsum fiber board and an attempt to dry or replace the backfill layer. The very sad reviews reporting such leaks make one think about the advisability of using dry screed technology in apartments with "problem" neighbors.

Image
Image
Image
Image

In cases where a dry screed is installed in a private house, in order to avoid leaks, it is recommended to purchase the Aquastop system, which guarantees the shutdown of water in the event of an emergency leak.

Image
Image

Accordingly, it is better to refuse to install a dry screed in the bathroom or in the kitchen, where the presence of water is inevitable and it is difficult to control the appearance of puddles on the floor. It is also undesirable to carry out the installation of a water heated floor inside a dry screed, since there is no guarantee that at some point the system will not depressurize.

It is unreasonable to use a dry screed in basement rooms (basements), since in such places there is inevitably increased air humidity, as a result of which the risk of condensation on the surface of the gypsum fiber board, as well as the absorption of moisture present in the air, by expanded clay particles, increases. As a result, sweating will appear inside the backfill layer, as a result of which fungus and mold appear.

Image
Image

Also, this option of a screed cannot be used in rooms experiencing high mechanical stress, for example, in shopping centers or work shops. This is due to the low resistance of gypsum fiber board, plywood or OSB to vibration loads and prolonged exposure to gravity: under such conditions, the coating sheets begin to burst and delaminate.

Construction device

The construction of a dry sub-floor is a complex system of alternating layers of vapor barrier, dry backfill (if necessary) and directly dry screed from super sheets or other floor elements.

To date, for various types of floors and different purposes, several options for arranging dry floors have been developed, which have significant differences. Since there are two main brands of dry floors on the domestic market - Knauf and Rockwool, the designs also differ depending on the manufacturer.

Image
Image
Image
Image

Rockwool offers a dry screed method called floating floors. It is suitable for creating substrates for modern floor coverings, while increasing the sound insulation of the room and reducing heat loss. Floating floors can be installed on substrates that have minor dents, dents or cracks.

The construction of a dry screed Rockwool "Floor Butts" or Rockwool "Acoustic Butts" can be of two types. The first option, in which the insulating layer is mounted in the frame from the lag:

  • The first layer on a concrete base is impregnation, on wooden floors - filing of the subfloor. On the ground floor, a bulk element is needed - sand.
  • The main structural element is wooden logs.
Image
Image
Image
Image
Image
Image
  • The next layer is a wind-waterproof membrane.
  • The direct insulating layer is represented by rock (mineral) wool Rockwool "Flor Butts" or Rockwool "Acoustic Butts".
  • A layer of vapor barrier film that covers the mineral wool.
  • The top layer can be made of two-layer plywood, OSB or large sheets of gypsum fiber board.
Image
Image
Image
Image

In the second option, laying is carried out without using a lag. It was this option that got the name "Floating floors", which are mounted on an old floor covering, the curvature of which does not exceed 10 mm per 2 m:

  • Floor Butts Rockwool Plates;
  • Vapor barrier Rockwool film;
  • Prefabricated screed from two transverse layers of sheet materials: OSB, plywood or large sheets of gypsum fiber board.
Image
Image
Image
Image
Image
Image

Knauf offers 4 dry screed options called Alpha, Beta, Vega and Gamma. All of these types are suitable for use as a base for flooring from parquet (piece or panel), parquet or laminate boards, various types of linoleum, ceramic and porcelain tiles, as well as various types of synthetic flooring (vinyl laminate, linoleum, carpet).

Image
Image

Option "alpha" suggested for installation on ceilings that do not require surface leveling. It is a "puff cake", which includes:

  • polyethylene film;
  • two-layer element GVLV (moisture resistant gypsum fiber sheet), measuring 500x1500x10 mm.
Image
Image

Option "beta" also suitable for use on already leveled surfaces. It consists of the following elements:

  • p / e film;
  • a backing made of porous fibrous or foam materials;
  • screed from GVLV elements.
Image
Image

Design "Vega" used for those surfaces, the level of which must be brought to uniformity. The components of this model are as follows:

  • p / e film;
  • dry backfill layer (fine-fraction expanded clay);
  • sheets of double GVLV.
Image
Image

Option "gamma" is the most difficult. It is used for leveling the surface and at the same time arranging sound insulation and consists of the following elements:

  • p / e film;
  • dry backfill;
  • single layer of gypsum fiber board, which is compensating;
  • a backing made of porous fibrous or foam materials;
  • layer of double sheets of GVLV.
Image
Image

It must be remembered that polyethylene film insulation is used for installation on concrete bases. For installation on wooden floors, a vapor barrier made of glassine is used - bitumen (refined) paper.

Special attention should be paid to the arrangement of a dry screed for the installation of piece or inlaid parquet. In this case, the selected design option is reinforced with an additional layer of gypsum fiber board, which is attached to the surface of the main sheets to strengthen and harden the screed. For this purpose, a large-format gypsum fiber sheet with dimensions of 1200x2500mm is used.

Image
Image
Image
Image

When arranging pipelines or underfloor heating inside dry floors, a "vega" -type construction is used, while the pipes are placed on the surface of the polyethylene film and covered with a backfill from a dry mixture. In cases where there is no need for backfill, pipes can be laid inside a substrate of porous fiber or foam materials. In this case, you will have to cut out recesses of the required size in them, and after installing the pipes, close these recesses with insulation, achieving a flat surface.

Image
Image
Image
Image

When interfacing with concrete walls and structures of partitions made of wood, it is necessary to install an edge (damper) tape. When moving from dry backfill to a monolithic base, for example, a concrete screed, the joint is made in the form of a step, while the seam is necessarily treated with a sealant.

Composition and materials

Since we are talking about a dry floor screed, an apartment owner who decides to carry out repairs on his own does not have to experiment himself, mixing cement, sand and water in order to make a high-quality solution. All processes within the framework of this technology are "dry", and the final result resembles a kind of "sandwich".

Image
Image

When installing a screed according to the method of the German company Knauf, the following materials are used:

Superfloor elements. These are sheets of gypsum fiber, which are homogeneous plates of a mixture of gypsum and cellulose, having a thickness of 20 mm and consisting of two sheets of gypsum fiber glued together. At the same time, the arrangement of individual sheets in this "sandwich" has a perpendicular direction to increase the rigidity of the structure, and to fix the elements in the process of arranging a dry floor, an offset of the "sandwich" sheets by 50 mm is provided, due to which protruding seam edges are obtained. The dimensions that are provided for ease of installation are 500x1500x10 mm or 500x1500x10 mm

Image
Image
Image
Image
  • Dry mix for backfill. The choice of this material is quite diverse:
  • Knauf proposes to use branded dry sand, which has a carefully checked grain size distribution, with a moisture content of no more than 1% and a compressive strength of at least 2.5 MPa.
  • Builders practice the use of fine expanded clay gravel, the granule diameter of which does not exceed 5 mm, which is the result of clay firing and is light and porous.
Image
Image
Image
Image
  • Another option for filling can be Compavit, which has a low level of moisture (0.5%), a volume of 0.1 to 5 mm and is essentially the same modified expanded clay, which has the manufacturer's proprietary guarantees (Belarusian enterprise ChPUP Vipol).
  • Vermiculite, which is used in cases where it is necessary to use the most lightweight materials. This material is the result of firing mica, in finished form it has almost zero moisture content, its weight is 2 - 4 times lighter than expanded clay.
Image
Image
Image
Image

Separating layer material. For installation on concrete bases, polyethylene film with a thickness of 0.1 - 0.2 mm is used. For installation on wooden floors, bituminous paper is used

Image
Image
  • Sound insulating layer. For this, several types of materials can be used:

    • Porous-fibrous filler, which can be represented by mineral or stone wool, ecover or Vibrosil E material.
    • Foamed filler. It can be expanded polystyrene or polyethylene.
Image
Image
Image
Image
  • Fastening screws. The length of the screws required for the installation of the "Knauf - superfloor" system starts from 19 mm and can be 22 mm, 30 mm and 40 mm, depending on the number of GVL sheets to be joined.
  • Primer composition … Knauf offers Knauf Tiefengrund as a primer.
Image
Image
Image
Image
  • Edging tape. Another name for this material is damper tape. This is a strip installed around the perimeter of the room for the purpose of sound insulation and linear deformation compensation, which is made of porous fiber or foam material. The thickness of such a tape ranges from 8 mm to 10 mm.
  • Adhesive composition. Glue is needed to connect the sheets of gypsum fiber board to each other. The manufacturer recommends the use of Kalan ok adhesive mastic or PVA glue.
Image
Image
Image
Image

Rockwool, offering its options for dry floor screed structures, recommends the following materials for this:

  • Basalt (stone) wool Rockwool "Flor Butts" or Rockwool "Acoustic Butts". This material has significant differences from the usual glass wool, since it is made from fibers of a mineral called basalt, is impregnated with a water repellent and is non-combustible. The size of the slabs is 1000 x 600 mm, the thickness can be from 25 mm to 170 mm.
  • Wooden logs. The wood must be dried, the size of the log for the frame depends on the number of layers of stone wool. The most commonly used lathing is from 50 mm lag.
Image
Image
Image
Image
  • Vapor barrier Rockwool film.
  • Windproof Rockwool membrane.
  • Plywood. Usually birch plywood 1525x1525x6mm is used.
Image
Image
Image
Image
Image
Image
  • OSB. This material is made of wood chips, in some cases it can have a water-repellent treatment. Sheet size - 2500x1250x6 mm, thickness varies.
  • GVLV sheet. It is a moisture resistant gypsum fiber with a size of 500x1200x12.5mm.
  • Self-tapping screws for fixing cover sheets.

Technology

The largest number of unfavorable reviews on floors installed on a dry screed is made up of complaints about lay laymen who do not follow the installation technology or who are not at all familiar with the existence of these rules. At the same time, quite a lot of reviews were given, confirming that, with proper installation, a dry screed can last more than 10 years and remain in a truly perfect condition, without height deviations and subsidence.

Image
Image

At first glance, the installation of dry floors looks simple, does not require the use of a special machine, so many builders undertake this work without bothering to study all the technological nuances. However, they will surely "emerge" in subsequent operation. Moreover, when arranging such "capricious" coatings as laminate, parquet or ceramic tiles over dry floors, expensive floor materials will also suffer: the laminate locks will begin to crumble, the tiles will crack, and the parquet board will crumble.

Image
Image
Image
Image

Accordingly, if the owner of the apartment cannot find real professionals with a good reputation who have the necessary equipment for arranging a dry screed, then it makes sense to carry out this work with his own hands, step by step and carefully performing all the necessary procedures.

Image
Image

Construction equipment, which is indispensable during installation, can be rented.

When laying a dry screed using the German Knauf technology, it is important to observe the following rules:

Use only branded dry mixes for backfilling: composite sand of the Knauf, Keraflur, AKZ or Kompavit brands of the original Belarusian production. The use of any other mixtures is possible only by professionals with extensive experience, who can at first glance distinguish the quality of the backfill and whether the fraction of the material meets the required standards

Image
Image
Image
Image

To carry out work of proper quality the use of special equipment is required, namely:

  • In order to most accurately set the level of the screed height, it is required to use a laser level.
  • The laying technology does not allow any metal elements to be left inside the backfill, since during the shrinkage of the backfilled mixture, they will become an obstacle to its uniform settling, therefore, the use of beacons familiar to builders is unacceptable. To determine the leveling height, use the unique Alu-Abziehlatte beacon profile, which is removed from the backfill after final leveling.
  • The rule for expanded clay produced by Knauf in three basic configurations will help to distribute the expanded clay sand as evenly and thoroughly as possible over the surface.
  • A rubber hammer will help to compact the dry mixture.
Image
Image
Image
Image
Image
Image
  • It is mandatory to install a damper tape around the perimeter of the room.
  • Also, do not save on laying a vapor barrier film (isospan C, D), which will help prevent the formation of condensation inside expanded clay. When laying Isospan, it is important to correctly determine which side it should be towards the backfill, since this material "breathes", letting in vapors only in one direction. On the floor, the rough side of the Isospan should be facing down. When laying this material, it is important to observe an overlap of layers of at least 150 mm, carefully gluing all joints with tape.
Image
Image

For the installation of the sub-floor, it is advisable to use the original sheets "Knauf-superfloor". The peculiarity of the structure of this type of GVLV allows you to assemble the structure of a dry screed as quickly, efficiently and reliably as possible. The presence of hydrophobic impregnation ensures the preservation of its linear dimensions when the gypsum fiber gets wet and then dries

Image
Image
Image
Image

The Danish company Rockwool, which offers two types of dry floor screed structures, also recommends adhering to the technological installation rules:

  • A damper perimeter of cut insulation strips must be laid out along the walls of the room.
  • Before installing stone wool slabs, a Rockwool vapor barrier film must be laid on the concrete floor, which must be placed with the logo facing up (so that the material acting as a valve works in the correct direction).
Image
Image
Image
Image
  • It is imperative to install a Rockwool windproof membrane on top of Floor Butts Rockwool boards, which must be located with the logo outward.
  • For laying Rockwool floating floors, it is necessary to use at least two layers of plywood, OSB boards or large GVLV sheets (the use of Knauf-superfloor elements is strictly unacceptable). Covering sheets must be laid with overlapping seams and the top must have a fiber direction perpendicular to the bottom. This ensures the rigidity of the structure required for the installation of the finishing floor covering.
Image
Image

Laying and installation methods

In order to start work on the installation of a dry screed using the Knauf method, you must first calculate the amount of required building materials. The main difficulty for a non-professional in this moment will seem to be the calculation of the number of bags of dry mix required for backfilling. Online calculators of expanded clay consumption can help with this.

The following characteristics must be entered into the online calculator:

  • The area of the room (m²), which is easy to calculate by multiplying the length of the room by its width;
  • The height of the minimum thickness to which it is required to raise the base base of the floors (mm): in this case, not only the height of the backfill, but also the size of the covering sheets must be taken into account;
  • The height of the floor drop in the room to be leveled with a screed (mm). To determine, it is necessary to measure with a laser level the lowest point and the highest point of the floor in the room and subtract the difference.
Image
Image
Image
Image

After entering the required data, the built-in gadget calculates the consumption of the mixture as per 1 sq. m, and in general for the whole room. With an accurate calculation of expanded clay, it is possible to avoid unnecessary purchases, thereby making repairs cheaper.

The rest of the materials are much easier to calculate. When contacting the store, it is necessary to inform the consultant about the length and width of the room and he will be able to calculate how many sheets of "superfloor", film, damper tape, etc. will be required.

Image
Image

Installation of a dry screed using the Knauf method includes the following stages of work:

  • Dismantling the old base, cleaning the surface from debris.
  • Application of a mark of the highest level of the screed.
  • Covering the surface with a waterproofing film with an overlap of canvases and fixing the edges with metallized tape. The edges of the foil should be raised by about 200 mm above the top mark of the screed.
  • Fixation around the perimeter of the room damper tape.
  • Covering the surface with expanded clay. It is better to do this without the formation of slides.
Image
Image
Image
Image
  • Determination of the design level at which the leveling profiles are installed (replacing the beacons present in the usual "wet" screed).
  • Implementation of work on leveling expanded clay, starting from the farthest wall of the room.
  • Distribution of expanded clay by a rule (leveling rail) according to a given level.
  • Cut out the elements of the "super floor", which begins with the fact that the seam edge of the sheet, which is extreme to the wall, is cut off.
  • An obligatory stage is the arrangement of "walkways" on the surface of expanded clay. For this, trims of GVL with a size of about 50 * 50 cm are suitable.
  • The process of laying the "super floor" starts from the wall, which has a doorway. Work is in progress from right to left.
  • It is desirable to tamp the expanded clay backfill, which can be carried out using a rubber hammer (carried out over the plates before fixing them).
Image
Image
  • Initial joining of GVL sheets to mastic.
  • Fixing joints with self-tapping screws with a pitch of 300 mm.
  • A mandatory moment when joining sheets is the alternation of seams.
  • For the subsequent installation of linoleum, vinyl laminate or carpet, seams and holes are sealed using a putty mixture.
  • For the subsequent laying of tiles, the surface is additionally treated with a primer for glue.
Image
Image
Image
Image

When installing a dry screed with insulation, the installation of a porous fiber or foamed filler is additionally added. In the event that there is no need to use expanded clay mixture for leveling the floor, the installation of the insulation is carried out directly on the concrete base covered with a vapor barrier film.

When preliminary leveling of the surface is applied, single sheets of gypsum fiber board are laid on the layer of dry mixture, on which insulation is laid, covered with a layer of double sheets of "super floor".

Image
Image
Image
Image

Which is better?

To date, there is no clear answer as to which screed is better: wet or dry. Each of these options has "contraindications", disadvantages and advantages. But in the case when it is required to carry out a significant leveling of the surface in a short time, there are no alternatives to a dry screed. If you remember how long a traditional concrete screed dries (and this period is from 20 to 28 days), it becomes clear why the method of dry leveling of floors has become so popular. Although the cost of a traditional screed is often cheaper than installing a "superfloor" with the use of original materials. Also, there are no other options, except for the use of dry screed, in houses with wooden floors.

Image
Image

Comparison between a dry screed device and a self-leveling floor indicates an approximate parity. The exact drying times for bulk mixes vary by composition and conditions. Usually after 12-20 hours the surface hardens enough and it is already possible to move on it. The self-leveling floor can be subjected to maximum load after 5-7 days.

Image
Image
Image
Image

Therefore, if the owners of the premises do not have a particular rush, it is worth considering the option of using self-leveling self-leveling floors.

Comparison of the cost of various brands of mixtures for self-leveling floors suggests that in terms of savings, they slightly outperform "super floors". In such a moment as installation, there is also approximate equality: following the advice of professionals, you can independently perform both types of work.

Testimonials

In order to decide on the choice of the type of dry screed and insulation of the base of the floor, you should go through the construction forums and read the reviews on how the various options manifest themselves during operation.

Positive reviews indicate that after 7-10 years of operation, dry floors made using Knauf materials and technologies do not have dips and the height difference is 1-2 mm per meter. There is a "chic" soundproofing, a fairly warm floor. It is believed that when installing a dry screed, there is no need to arrange warm floors; you can walk with bare feet on ceramic tiles laid, for example, in the corridor.

Image
Image

It is reported that sheets of GVLV can withstand the weight of furniture well, and inside the bulk it is convenient and safe to hide electrical cables. Also called such a plus of installing a dry screed, as the ability to carry out work at sub-zero temperatures.

Image
Image

As a plus, they also note the fact that, if necessary, such a floor can be easily opened for repairing the built-in “warm floor” system, for backfilling, replacing the coating. Users report that even if there is a nuisance and the neighbors upstairs "arrange a flood", dry floors can be opened and dried. At the same time, some owners advise not to lay a vapor barrier film under the expanded clay just for faster drying in case of leaks.

Image
Image
Image
Image

Negative reviews are mainly associated with poor quality work. "Krivoruk" masters, who "somewhere did not sleep enough, but somewhere they overestimated the level", did not tamp enough, left gaps near the walls - the main reason for complaints, since as a result of poor-quality work, the dry floor begins to "walk", the tiles laid on top of it, cracks. This is especially true for large-format tiles, which are especially demanding on the quality of the screed.

Image
Image

A dry screed made in a bathroom leads to cracking of tiles in the corners of the room, which users associate with high humidity in this room.

Summing up the statements, we can draw the following conclusion: when performing a dry screed, you should not save on materials. You need to do the work with high quality and strictly according to technology. In this case, there will be no complaints about dry floors, regardless of the period of use.

Interesting renovation ideas

For the creation of unusual interiors, the best are old houses, the so-called "stalinkas", or buildings erected at the beginning of the XX century. In such houses, high ceilings, spacious rooms, bay windows or balconies are often found. However, in most cases in such buildings, the floors are made of wood and cannot be leveled with conventional screed types. It is in such cases that the use of a dry floor screed is relevant.

An interesting option would be transformation of a balcony-bay window into a dining area. To implement this idea, you must:

  • Remove the balcony door;
  • Insulate the balcony;
  • Dismantle the old floor covering on the balcony (if necessary, in the adjoining room);
  • Equip a warm floor system;
Image
Image
  • Lead the power supply cables;
  • Level the floor of the balcony and adjoining room using a dry screed;
  • Lay laminate on the floor of the room, on the floor of the balcony - ceramic or porcelain stoneware tiles (marbled or with marble inserts or with mosaic inserts);
  • Conduct panoramic glazing of the bay window.
Image
Image

Similarly, you can implement transformation of the loggia into a study. In this case, it is also recommended to apply the dry screed option, since the balcony base has restrictions on maximum loads:

  • Dismantle doors and balcony block;
  • Dismantle the old floor on the balcony;
  • Carry out insulation and glazing of the balcony (to increase the volume of the room, glazing with "take-out" will be a good choice;
  • Carry out electrical wiring;
Image
Image
Image
Image
  • Arrange a dry screed with simultaneous installation of the "warm floor" system;
  • Carry out the laying of the floor covering;
  • Paste the walls with wallpaper or sheathe with panels, artificial stone, etc. at your own discretion;
  • Install sliding panoramic glass doors.
