Cuhaya floor screed: price, pros and cons, reviews

Elimination of "wet" processes faster and easier construction. Not surprisingly, therefore, that after the appearance of appropriate technologies to them was riveted attention by specialists. But not only professionals interested in the dry floor screed: price, advantages and disadvantages, Expert reviews. This knowledge will be useful to any owners Real estate. They will help them make the right decisions when choosing a suitable technique for the radical reconstruction, overhauls, erection new buildings.

Dry floor screed: the pros and cons, real cost of the project

For a proper understanding of the benefits of the new technique disadvantages of older technologies need to be clarified. The starting materials for the concrete screed have significant weight. Transporting them to the object, loading and unloading operations accompanied by high labor costs.

To prepare the mixture of sand and cement need considerable physical effort. It is recommended to fill the room tie in one working day. This will ensure that the same parameters of the structure and characteristics of a good consumer layer. To fulfill this condition have to buy or rent concrete mixer, Vibration machine, other special equipment.

The presence of water in a solution implies the need to secure the bottom waterproofing. Full hardening layer is 25 - 30 days. Only after this period can be set finishes, start operation underfloor heating. During drying it is necessary to maintain a comfortable temperature and the level of humidity. laying concrete screed is not carried out in frosty conditions.

Meanwhile, the damage can not be ruled wiring, pipeline. If we consider a dry floor screed, pros and cons, reviews, price, must remember the simplicity of disassembly. It can be done independently, without unnecessary noise and pollution, with the use of available tools. Permissible re-use of certain materials.

The main parameters of technique

The above disadvantages are eliminated in part or fully by the following construction.

In this figure shows the typical distribution of the layers during the installation of dry floor screed in the apartment:

• reinforced concrete slab intermediate floor cover film to prevent the flow of moisture from below.
• The edge tape is in this case not only compensates for thermal expansion as when laying a "wet" screed. It also does not pass water, which deteriorates the insulating properties of the backfill.
• This is followed by the main layer. It is formed of a solid granular materials.
• In this embodiment, two coatings applied gipsovolokonnyh plates. This decision strengthens the foundation. Therefore, the top can be installed without any restrictions linoleum, laminate, Other topcoats.

Already at this stage, without a detailed study of the installation, you can draw preliminary conclusions about the merits of device technology, dry floor screed:

• For the installation, you can use lighter materials. They are not difficult to move.
• Acceptable performance of work upon convenient for a particular person time schedule. Delays in filling the filler not degrade the characteristics of the final consumer layer.
• Working operations are quite capable of one person. Do not need to buy expensive equipment, the study of complex technologies.
• After laying this screed is ready for immediate use in accordance with the purpose. If you need to seal glue gipsovolokonnyh plate, his hardening does not take more than a few hours.
• The created structure may be disassembled, upgrade without undue cost.

But this is - not a "one-time" purchase. This versatile technique is useful in the future for fixing boards gender, address other practical problems

Important! We should not forget about the hygroscopic fillings. If you had to make a long break, it is necessary to provide a low level of humidity in the room.

materials Overview

As the filling is well suited for dry expanded clay floor screed. -Low price it, so even in large facilities will eliminate excessive costs. In this construction, use is not standard, but ground to a 5- 6 mm granules. This porous material is formed from a fired clay. It is ecologically safe, contains no allergens and other dangerous substances. Its beneficial properties are preserved for decades in an unaltered state. This creates a layer of porous material with excellent soundproofing and insulating properties.

Vermiculite - a material created by nature during the weathering of mica rocks. It is calcined to remove moisture and creating a plurality of pores. During heating source size increases more than 12 times, improved insulating properties.

Such a filler is resistant to various kinds of external influences. He was not able to spoil even the acids and other potent chemicals. Vermiculite is used for filling fire partitions. It should be borne in mind that it is very good at absorbing moisture, hence it is important to use the appropriate protective layers.

Another popular filler, perlite, volcanic rock created from sawmills. Moisture removed therefrom by heat treatment. This material is chemically inert and safe. It has excellent insulating properties, resistance to high temperatures.

The following table marked features of materials for the top layers screed.

Picture	Name / Reduction	Benefits	disadvantages
	Fiberboard / MDF	Durability, low cost, uniform structure, good insulating characteristics.	Relatively large weight, complexity of machining.
	Plasterboard sheet / GCR	Cheap, lightweight material.	Partly strength, ability to absorb water.
	Gipsovolokonnyh sheet / GVL	The light weight, improved strength due to the presence in the structure of the fibers, some modifications are resistant to moisture.	It does not absorb water modifications are more expensive than standard products. The strength of less than Particleboard.
	Plywood	High strength, environmental cleanliness.	Education deformation and damage to the structure when absorbing moisture, the high cost.
	Styrofoam plates	Light weight, moisture, excellent stability insulation characteristics.	Only at high density to provide sufficient floor coverings strength.

opinions of experts

To find out the pros and cons of the dry floor screed should be explored in addition to price reviews of professionals. The following are recommendations that are relevant to the choice of materials and the practical application of technology.

The above filling quickly absorb moisture to deteriorate their insulation performance. Vertmikulit should buy only liability of the seller. Insufficient quality material may contain impurities of asbestos, which are better exclude structures in residential premises.

His fall asleep gently. The room is closed doors and windowTo eliminate drafts. It is less durable compared with vermiculite. The upper layers are encouraged to establish with the use of rigid plates that provide protection against mechanical impacts.

All modern materials formed from wood wastes (shavings, fiber), to better withstand high humidity compared to the original natural material. If you select plywood, It is necessary to purchase the product in a special, water resistance performance.

Such materials provide additional insulation. To provide resistance to mechanical stress necessary to choose the plate at a density of 35-40 kg per m. Cu. It should be noted that the total thickness of the layers increases. This decision only applied at a sufficient height ceiling in room.

Installation of dry floor screed own hands: video, photos, written instructions

In this video you can learn how to create a multi-layer coating.

Next, description illustrated technology separate actions:

Picture	Algorithm
	The old flooring is removed up to the concrete overlap. Remove debris, plaster. Sealed cracks, eliminate other defects.
	Align perfectly the surface is not necessary, because it is for this set screed. However, it is necessary to remove the sharp protruding parts that could damage waterproofing.
	The contour of the room set damper tape. To pre-fabricated product with the adhesive layer joins firmly, should first align the bottom part of the wall, clean it from dirt.
	Cover the entire surface of the base thick polyethylene film. In the joints using adhesive tape, the two layers overlap, to ensure a good seal.
	Leveling bulk material which is via such devices. Aluminum guides with pre-set level verification of horizontality.
	To GVL or other gypsum boards provided sufficient strength, they are assembled in two layers. The joints are displaced. Fixation perform adhesive composition and screws.
	When using only one row of Styrofoam plates can be used with sufficient density. They are placed in a checkerboard pattern. Advantageously used on a flat surface (without walls) interlocks with the product at the ends. If, in addition to seal the joints with tape, filler additional protection against moisture is created.
	Styrofoam plates mounted on a damper pad on which is placed laminate.

Note! Their description of this can be seen that the price of dry mixes for floor screed - it's just one of the cost items. The total cost is calculated by taking into account all the components of a specific project.

Separately it is necessary to examine the features of the use of this technology in conjunction with the installation of heating systems.

When the pipe is installed inside the classical concrete screed, it carries out its functions effectively. Bulk fillers pose obstacle applies heat, increase the inertia.

Is it advantageous to dry floor screed: the price per square meter and other findings

The relatively high price of dry floor screed Knauf explained reliable warranty reputable brand. In this case, the manufacturer provides unity technical parameters of each consignment, no harmful to health impurities. With such materials work convenient and easy.

However, a more in-depth study, you can check that in the no special components. It used conventional concrete block. Its use is proposed for the same technologies that are described in this article. Thus, if we consider all the above suggestions, you can manually optimize the value of the dry floor screed.
