Various options are applied to align the floors. These are traditional concrete ties, dry mixes for floors, wooden lags and other methods. Recently, the so-called self-leveling mixtures are popular, which after its fill provide the most evenly and smooth surface. Filling the floor by self-leveling mixture is made in several stages, it is relatively simple, but demanding. It is easy to work with the compositions, they are perfectly suitable as surface preparation for any outdoor material, can act as self-coating in garages, warehouses, industrial or commercial facilities.

Floor Filling Process
Preparation of the base is simple, it includes such steps:- The floor must be carefully examined, after which it is necessary to determine which defects are observed.
- After that, it should be proceeded to eliminate them, if necessary, the base is dried.
- From the surface all dust and garbage is removed.
Filling of floors by self-leveling mixture is not necessary without the following materials and tools:
- Dry mix for fill;
- Capacity for kneading;
- Drill with a nozzle mixer;
- needle roller;
- Special studded shoes.
Kneading solution
Required tools for filling the floor.
To level the floor in all the rules, you must first intervene the solution. This stage is one of the most responsible, since the quality of future coverage depends on it. For example, too much water leads to the fact that the fluidity is excessive, and the strength is low. The lack of water, on the contrary, leads to the fact that the mixture on the floor is distributed difficult and bad, the quality is low. When mixing the mixture, you must follow the instructions that are given by the manufacturer. . You can pre-knew the test portion, see how it spreads it is whether it is necessary to add or drop the amount of water.

Check the quality of the mixture simply, for this you only need to take an empty spray from the aerosol. Its diameter should be 5 cm, and the height is about 4.5 cm. The bottom is cut off, and the lid is removed. After that, a slightly mixed solution is poured into the lid, turn it out so that the mixture can crush over the surface. After about 2 minutes, the diameter of the resulting puddle is measured. If everything is done correctly, then it must have dimensions of 16-18 cm. If the diameter is less, then it is necessary to add water. If it is more, then the amount of water is too large.
To pour the self-leveling mixture to be high-quality, you must first pour water in the container, after which it is gently filled with a mixture, stir it.
There should not be any lumps in the resulting mass. When preparing the mixture, it is necessary to remember that the fluidity is saved only 40 minutes. Therefore, work should be carried out as quickly as possible. It is necessary to mix in small portions, otherwise the solution will be simply unsuitable for use.

Scheme of preparatory work before the fill of the floor by self-leveling mixture.
To pour the floor with a mixture with a high quality, it is recommended to start all work from a long corner. The process itself is simple, even newcomers can cope with him that do not have any experience. It is only necessary to comply with all the recommendations. You need to pour a new portion in such a way that the boundaries between the individual layers can be seen. It is important not only for the appearance, but also for the strength of the future design. Therefore, it should be done quickly, without interrupting the trifles.
During operation in a thin place, the coating thickness can be from 5 mm, and for the thick place, this value must be up to 20 mm. Such parameters will affect quality, so you should not neglect this rule. It is necessary during the markup to immediately determine such differences. Then it turns out exactly calculate the cost consumption, and performing work quickly, saving also tools.

Pour the floor must be correct to serve as longer as possible. The composition is poured in small portions, after which it is distributed by a special needle roller. It is necessary to walk on the floor only in special shoes with spikes on the sole, this will not make it possible to damage the surface. The needle roller allows not only to correctly distribute the mixture, but also get rid of air bubbles that remain in it after the fill and adversely affect the quality.
The scheme of using a self-leveling mixture.
After the work is fully completed, it is necessary to leave a drying coating. It should be protected from drafts and bright sunlight. Therefore, the windows in the room are required to close, the surface is covered with a polyethylene film. It is necessary to keep the film about two days, after which it can be removed. The drying time of the filling floor depends entirely on what kind of thickness it is. Most often it is 2 weeks, although it may be necessary more time.
The feature of the technology is that there is no need to use special lighthouses and other materials for alignment. This greatly facilitates work, makes it much faster. Drying time is required less than for a cement screed that can dry 4 weeks.
Is it possible to use a self-leveling mixture for floor floors?
Is it possible to align a wooden base with such a mixture? Specialists do not advise such work, since the floor is hard. Wooden base can not withstand such a load, especially if it is dilapidated. On the screed, it will also be reflected in the best way, it will begin to quickly be covered by cracks and collapse.

Despite this, many manufacturers of filling floors based on cement state that the mixtures for aligning the wooden coating can not be applied not only, but even need. However, following this recommendation leads to the fact that it is soon needed repair not only screed, but also the grounds, and these are considerable cash spending. Therefore, it is not worth risking, there are many more economical solutions for wooden floors, for example, the use of adjustable lag.

The self-leveling mixture is used if it is poured into a newly renovated and strong base, which can well withstand the load. The fill process differs little from the standard. You must first prepare the basis, carefully examine it. If there are cracks or other defects, you should immediately close them, replace the weak items to new, remove all the boards with the traces of rot. After that, the solution is mixed in the proportions specified by the manufacturer, poured from a long corner. It is necessary to work in the studded shoes, the mixture is distributed by a needle roller. It may be necessary to process the surface with a special mop with a tip of rubber.
Self-leveling self-leveling mixtures are an excellent option to make semi precisely those properties that are necessary. The surface is obtained not only smooth, but also smooth, durable. It is great for laying any outdoor material. The process of device of such a screed is simple, it is a fill of the mixture to the base surface, its needle roller distribution. The composition easily takes exactly the form that is required of it. As a result, it turns out a smooth and smooth base.
