Mixture for screed (alignment) of the floor

The owners often face the problem of uneven sexes not only in the buildings of the old -style, but also in new houses. Clear business, you will have to take place with laying tiles, parquet or laminate, since the floor should first be leveled. The excellent material to accelerate this procedure and improve the quality of the result is aligning ready -made mixtures for screeding, since the modifiers that are part of such substances are characterized by good elasticity, adhesion and high self -leveling ability.

Features of mixtures for aligning the floor

Unfortunately, even in the newly built high -rise buildings of even floors it is practically impossible to find. But the main purpose of the floor screed is to align the concrete base for laying the flooring or further finish. If the floors are not leveled, then on the finish flooring all defects in the black screed of tubercles and cavities will be clearly visible.

Previously, to align the floor, the construction solution was made directly at the construction site, the recipe in such conditions was rarely observed, as a result of which the consumption of components increased. Today, in the factory, construction mixtures are produced, which already contain all the necessary components in the correct ratios.

The mixtures for aligning the floor are fast -hard -harding plastic compositions that have good fluidity. Usually they are manufactured in the form of a dry composition or concentrate ready for use, to which sand is mixed, they are shut up in the process of working with water and, spreading, filling out all the hollows and unevenness of the draft floor qualitatively.

Dry mixtures for floor screed have undoubted advantages over cement, which is traditionally used for similar purposes:

1. Drying time. Ready mixtures are inherent in the speed of drying on average 10-15 days, you can walk on the surface after 5-6 hours and lay the finish coating on the floor after half a day, although for urgent repair you can find special rapidly drying mixture for leveling the floor, which makes it possible to move through two hours.
2. Quality. Small -fractional fillers used in mixtures for aligning the floor (about 250 microns), unlike ordinary cement, allow you to get the perfect surface with a minimum probability of drawdown.
3. Convenience of work. The applied layer of the composition can have a thickness of 5 millimeters and above, and this is a wonderful find for rooms with low ceilings or for cases when you need to smooth out small irregularities. In addition, even an amateur can get a high result if he clearly follow the instructions that are present on the packaging of each mixture for the floor screed.

Composition of mixtures for aligning the floor

Dry mixtures for screeds are divided in their composition and the type of binding into two large groups used: cement -based mixtures and gypsum -based compounds. Substances based on cement were found to equalize surfaces in residential and public buildings in external and internal work. Substances on a gypsum basis are used mainly for the installation of screeds inside the buildings.

Gypsum mixtures are becoming more and more popular every year, because gypsum is environmentally friendly, natural material, which is also a good heat insulator. The screeds based on gypsum are faster than cement harden, have the ability to adjust the moist and temperature regime in the premises, absorbing moisture with its excess and, accordingly, giving it to its lack. Gypsum mixtures are simply ideal for parquet, since when laying such a floor covering on a gypsum screed, it will not be dry out.

Another feature is the presence of special additives in the mixture for screeding the floor, which increase the plasticity and fluidity of the material. Moreover, in some types of mixtures, synthetic fibers may be present. Due to the specific composition of the mixtures, the appearance of cracks in the screed becomes unlikely.

Varieties of dry mixtures for the floor

By the method of working with them, all mixtures for aligning the floor are divided into two categories:

1. Self -leveling mixtures that independently spread almost without human participation and take a perfectly even horizontal position. If the room has impressive dimensions, then you can pour the mixture using a pumping device, that is, a pump. Self -growing compounds harden quickly and are intended for leveling the bases and preparation of floors from concrete, gypsum, wood for the subsequent laying of traffic jams, ceramic tiles, carpets and linoleum. At the same time, you must understand that such a base cannot be operated without a finish flooring, since such an unprotected surface is dusting and has a tendency to absorb water and oils.
2. The leveling construction mixtures for floor screed, which need to be divorced by a spatula and require an active participation of a person in creating a screed. In fact, these compounds are gross mixtures for screed. They are used for the first layer and alignment of the floor in cases where it is very tuberous, to create slopes and arrange warm floors.

The purpose of the floor screed mixtures

The mixtures for aligning the floor also differ in purpose. To align the concrete floor, mixtures are made that tend to harden in a matter of minutes. Mixtures that do not provide for further decoration are also made, they are customary to use on the surfaces of the porch and balconies. Many companies represent the compositions that are intended for gross alignment of the floor with large irregularities and tubercles, and thin -layer mixtures for finishing.

The mixtures for primary leveling are customary to apply 10 - 80 millimeters thick, as a filler to increase the strength of the screed, there are components of large fractions: ground granite, large sand, expanded clay gravel. However, such bulk mixtures cannot guarantee obtaining a perfectly flat surface, because they have reduced fluidity.

The finish mixtures for floor screed are more expensive, they can be used as the basis if you plan to lay cork or thin roller coatings. It also makes sense to use only the finish mixtures, if the surfaces on the floor are small - no more than 1 centimeter. The finish compositions are customary to select depending on humidity in the room and the intensity of exposure to the draft base.

Specialized elastic mixtures are presented on sale, with which you can repair ceramic tiles, asphalt coating and old wooden floors. Using self -enforcing mixtures, you can tighten the level of one black base under another if the coatings have various tolerances in height, for example, parquet and tiles.

Dry mixture manufacturers for gender

Consumers are offered to the attention of various cement mixtures, which differ in between the composition, the quality of the ingredients and other parameters. One of the well -known manufacturers of mixtures for screeds is the company Teplolux. The composition of the product Teplux-Glims is maximally adapted to the needs of customers who want to equip a warm floor in the room.

Under the Vetonit brand, special mixtures are presented for creating perfectly even surfaces. A self -leveling composition called Weber.vetonit 4310 can be used when creating a screed under warm floors, applied to various bases, including wooden structures and old tiles. The mixture for screed the warm floor Weber.vetonit 4100 freezes after a couple of hours and can be used even in wet rooms.

Under the trading name of Alfapol, mixtures are made that provide protection against some types of electromagnetic waves, which come from electrical devices. The company produces Alfapol LMB, Alfapol MP, Alfopol TZP, which differ in composition from many similar goods.

Under the IVSIL brand, dry mixtures are made to create finishing and black screeds. The manufacturer recommends using an IVSIL TIE-ROD-I plater for screed for water, electric and IR heating systems. The fast-hard-hardened IVSIL Express-Basis compounds are also suitable for these purposes, and only 12 hours are required to dry completely.

The compositions for screeds and bulk floors under the stamps of Startoline and Nizhine will help to create a perfectly even base and lay the electric cable and pipes in a minimum compressed time. Under the Bergauf brand, several compositions are available, which are designed to prepare the bases for future finishes and differ in the thickness of the layers, drying time and other parameters.

Thus, the finished dry mixtures for the floor screed allow you to quickly and conveniently prepare a solution for aligning the surface, which qualitatively fills all the cracks and irregularities of the base. These materials have a lot of advantages over traditional options that were used before, namely the simplicity of filling, the optimal consumption of the mixture for screed, a short drying time and a high indicator of the quality of the material. Just add water and you can start work!
