One of the important tasks during the repair is to fill the floor. The price of these services is 300 rubles per m 2 . The aesthetics and durability of the finish flooring will depend on this. The need for alignment may arise not only during a complete reconstruction, but also during a simple repair. There may be several solutions, but the most common is mounting the screed using self-leveling mixtures.
Rough leveler
The leveling device for the floor can be used to eliminate serious defects in the base, on which there are deep potholes and chips, as well as cracks. In this case, the floor can have a big difference in differences. To do this, it is recommended to use a rough leveler, which looks like a dry mixture of coarse particles. For use, the composition must be combined with water. Filling the floor (the price of such services was mentioned above) is a fairly thick layer when using a rough leveler. The screed does not crack after drying and withstands heavy loads.
The most common base component in such mixtures is cement, which provides the necessary strength and adhesion to the surface. If the mixture is designed to form a 5-10 mm layer, then you should not make it more massive, since it can crack due to stress. Before leveling, it is worth solving the issue of the number of layers. In the presence of dents with a depth of more than 10 mm, it is recommended that they be sealed in advance with special mixtures or a leveling compound. Only after it is recommended to fill the screed on the entire base of the floor.
Finish leveling
The leveling device for the floor can be designed to form an absolutely smooth and even base. Therefore, before using such mixtures, the floor must be leveled using the basic composition. It has finer fractions, and when water is added it forms a plastic composition that is easily laid on the surface. Finishing levelers are more complex in composition than those described above, since more stringent aesthetic and practical requirements are imposed on them.
Mineral polymer components are added to the components during the manufacturing process, which make it possible to obtain a leveler with the qualities of strength and high resistance to physical influences. The basic components in this case are most often gypsum and cement, which determine the main quality and possibilities of the future floor.
Solution preparation
If you decide to use a floor equalizer for work, you should familiarize yourself with the technology of preparing the solution. After surface preparation, marking and installation of beacons are completed, it is possible to carry out surface priming. Then a solution is prepared, for which a container of the right size is needed. Pure water is poured into it, and then a dry leveler is poured.
In the process, the solution should be mixed, for which a drill with a special nozzle is used. The tool should be set to low speed, in the process you will need to get a homogeneous mass without clots and lumps. The leveling agent for the formation of the base layer becomes thick, and excess water can cause the mixture to foam. From this, the mechanical strength of the composition will decrease, the material will delaminate after drying. Therefore, you must strictly follow the manufacturer's instructions.
Application technology
The leveling device for the floor at the next stage is laid out on the base, distributed over the surface. If the solution is quite thick, then it will spread poorly, so it should be distributed manually using a spatula, rule or even board. To get rid of air bubbles and interlayers, a needle roller should be used. The viability of the solution will remain for half an hour from the moment of preparation.
The marking performed at the previous stage should be used as technological zones during pouring. This approach is convenient if you have to work with an area of more than 20 m 2 . Such zones are recommended to be filled alternately. The self-leveling floor leveler is left to dry completely. In this case, the room should not have drafts, and if the air inside is too dry, then the floor surface should be covered with polyethylene.
Technology using the finish leveler
If it is necessary to obtain a perfectly even and smooth surface, then mixes should be used to finish floor leveling. There should not be too large elevations on a rough basis. The mixture is diluted to a more liquid state. For such a leveler, a thorough primer is required, in some cases waterproofing is necessary, which is important for a multi-storey building, when there is a risk of flooding of neighbors from below.
The base must be freed from exfoliating elements of the finish coat, dirt and dust. For final alignment, beacons are not required, since the solution will flow independently. The self-leveling floor leveler should have a layer of several millimeters, some solutions are designed to form a layer of up to 3 cm. It is important to ensure the appropriate conditions in the room under which the temperature should not drop below + 10 °. Leveling should be done with a spatula or other tool.
Wizard tip
The finish floor should be poured on separate platforms. The surface for this is previously divided into zones, one of which you can fill in 15 minutes. At the same time, it is necessary to fill in at a time, without forming technological breaks. Only in this way you will achieve good quality and durability of the floor. It is important to exclude the quick drying of the mixture, since in this case cracks or air bubbles can form on the surface inside.
Consumption and technical characteristics of the Volma-Level Arena
Mixtures "Volma" are on sale today in a large assortment. Among them you can find the Volma-Level Arena, which is a dry mix based on high-quality cement, modifying additives and fractional natural fillers. The composition is highly durable, frost-resistant and non-shrinking. It comes in 25 kilogram bags. Using it, you can form a layer from 5 to 60 mm.
To prepare 1 kg of the dry mixture, approximately 0.2 liters of water will be consumed. If there is a need to shut all 25 kg at once, then 5.75 liters of liquid should be added. With a layer thickness of 10 mm, approximately 16 kg per 1 m 2 of surface will be required. It is necessary to use the finished mixture for 60 minutes, and the air temperature can vary from +5 to +30 degrees. The surface can be used for walking after pouring after 24 hours at an average ambient temperature during drying at + 20 °.
Cooking Volma-Level Arena
Mixtures "Volma" should be used according to a certain technology, which provides for the correct preparation of the base and preparation of the mixture, as well as the procedure for work. The surface must be cleaned of dirt, the base is treated with a primer, and then the floor level is indicated. In places where the base adjoins the walls, a gasket of damping materials should be installed. The optimal pouring area at one time is from 20 to 25 m 2 . Water is poured into the container, then the dry mixture is poured and mixed for 3 minutes with a professional mixer. The solution settles for 5 minutes and mixes again.
The resulting solution should be used within an hour, and to speed up the pouring process, it is recommended to prepare a solution of 2 bags, for this a capacity of 90 liters is needed. This self-leveling floor, the flow rate of which was mentioned above, should not be prepared in a concrete mixer. Among other things, an overdose of water should be excluded.
Technology
Once the mass is cooked, it can be poured to the surface, excluding technological breaks for more than 10 minutes. This will ensure the continuity of the pouring process. While the mixture is leveled, it is necessary to mix the second portion of structure. After pouring the solution, you need to get rid of the levels and remove bubbles from the mass using a construction mop. During hardening during the first two days, direct sunlight should be excluded and natural ventilation should be provided. In this case, the use of heat guns is prohibited. Laying the coating on a level floor can be done 7 days after pouring. Residual surface moisture during laying of subsequent materials should not be more than 1%.
Finishing leveler brand Bergauf "Boden-Level"
Final floor leveling can be carried out using a mixture of brand Bergauf "Boden-Level". It is a composition for leveling the surface in rooms of different humidity. The rough floor can be a bulk floor (except for gypsum), a cement-sand screed, as well as reinforced concrete slabs and monolithic concrete. In the latter case, cracks must first be repaired. The mixture has a gray color, the maximum fraction of the components is 0.63 mm.
When laying a 10 mm layer, the consumption will be 16 kg per 1 m 2 . The viability of the mixture is maintained for 30 minutes in an open container. Partial floor loads can be tolerated 8 hours after pouring. It is noteworthy that after three days you can lay the finish flooring. The product can be used without restrictions, but it is first necessary to repair cracks and large defects of the base.
Leveler for wooden floor
When considering how to level the floor, you can pay attention to Neu auf Alt, which is a self-leveling mortar based on cement. It is designed to work with complex bases, including wooden. In one application, you can form a layer whose thickness will vary from 1 to 20 mm. For wood, the minimum thickness is increased to 5 mm. The mixture is flexible, quickly hardens after pouring and can be applied to old tiles, paint and other coatings. This mixture is capable of replacing thick-layer, costly solutions such as chipboards or bases based on cement and chips. With Neu auf Alt you can form a flat surface that is applicable for subsequent work in the form of laying ceramic tiles or applying paint.
On the surface after 5 hours you can walk, and after 12, it is permissible to begin subsequent work. Alignment of the wooden floor can be carried out at a temperature of 5 to 30 °. The temperature resistance of the coating varies from 0 to 70 °. Among the ingredients you can find special cements, synthetic additives, quartz sand, anti-foaming agents and components that contribute to cracking. If you level the wooden floor using the described mixture, you will get an environmentally friendly surface that does not contain quartz flour.
