For floor leveling, differentoptions. These are traditional concrete screeds, dry mixes for floors, wooden lags and other methods. Popular so-called self-leveling mixtures, which after their pouring provide the most smooth and smooth surface. Pouring the floor with a self-leveling mixture is done in several stages, it is relatively simple, but demanding. Working with the compounds is simple, they are excellent for preparing the surface for any flooring material, they can act as an independent coating in garages, warehouses, industrial or commercial buildings.

The process of filling the floor
Preparation of the base is simple, it includes the following stages:
Pouring floors with a self-leveling mixture is not without the following materials and tools:
- dry mixture for pouring;
- mixing tank;
- a drill with a nozzle-mixer;
- Needle roller;
- special studded shoes.

Mixing of the solution
The necessary tools for pouring the floor. To level the floor by all rules, you must first mix the solution. This stage is one of the most responsible, as the quality of the future coverage depends on it. For example, too much water leads to the fact that the fluidity is excessive, and the strength is low. Lack of water, on the contrary, leads to the fact that the mixture on the floor is distributed hard and bad, the quality is low. When mixing the mixture, it is necessary to follow exactly the instructions given by the manufacturer. Beforehand, you can mix the test portion, see how it spreads, whether it is necessary to add or subtract the amount of water. Check the quality of the mixture simply, for this you only need to take an empty can from the aerosol. Its diameter should be 5 cm, and the height - about 4.5 cm. The bottom is cut off, and the lid is removed. After that, a little mixed solution is poured into the lid, turning it over so that the resulting mixture can spread over the surface. After about 2 minutes, the diameter of the resulting puddle should be measured. If everything is done correctly, then it should have dimensions of 16-18 cm. If the diameter is less, then you need to add water. If it is larger, the amount of water is too large. To fill the self-leveling mixture with a high-quality mixture, you must first pour the water into the container, then gently fill the mixture, stir it. In the received weight there should not be any lumps. When preparing the mixture, it should be remembered that the fluidity remains only 40 minutes. Therefore, the work should be done as quickly as possible. Mix in small portions, otherwise the solution will be simply unusable. Back to contents</a>
Filling the floor
Scheme of preparatory work before pouring the floorself-leveling mixture. To fill the floor with a prepared mixture of quality, it is recommended to start all work from the far corner. The process itself is simple, even beginners can cope with it, which have no experience. It is only necessary to comply with all recommendations. You need to pour a new portion in such a way that the boundaries between the individual layers can not be seen. It is important not only for appearance, but also for the strength of the future design. Therefore, it is necessary to work quickly, without interruption on trifles. During operation in a thin place, the thickness of the coating can be from 5 mm, and for the thickest place this value should be up to 20 mm. Such parameters will affect the quality, so you should not neglect this rule. It is necessary to immediately determine such differences during the markup. Then it will be possible to accurately calculate the consumption of the composition, and work quickly, saving money and money. Pour the floor properly, so that it lasts as long as possible. The composition is poured in small portions, after which it is distributed with a special needle roller. Walk on the floor only in special shoes with spikes on the sole, this will not damage the already flooded surface. Needle roller allows not only to correctly distribute the mixture, but also to get rid of air bubbles that remain in it after pouring and negatively affect the quality. 
Scheme of using a self-leveling mixture. After the work is completely done, leave the coating to dry. It should be protected from drafts and bright sunlight. Therefore, the windows in the room must be closed, cover the surface with a plastic wrap. Keep the film should be about two days, after which it can be removed. The drying time of the filler floor depends entirely on the thickness of the floor. Most often this is 2 weeks, although it may take more time. The peculiarity of the technology is that there is no need to use special beacons and other materials for leveling. This greatly simplifies the work, makes it much faster. Time to dry is required less than for cement screed, which can dry for 4 weeks. Back to contents</a>
Is it possible to use a self-leveling mixture for floors made of wood?
Is it possible to level a wooden base suchmixture? Specialists do not advise doing such work, since the floor turns out to be heavy. A wooden base can not withstand such loads, especially if it is dilapidated. On the screed this will also not be reflected in the best way, it will begin to quickly crack and break down. 
Scheme of construction of rough floor oncombined screed. Despite this, many manufacturers of self-leveling floors on the basis of cement declare that mixtures for leveling the wooden coating can not only be used, but even necessary. However, the adherence to this recommendation leads to the fact that soon it is necessary to repair not only the screed, but also the grounds, and this is a considerable amount of money. Therefore, there is no risk, for wooden floors there are many more economical solutions, for example, the use of adjustable lags. A self-leveling mixture is used if it is poured onto a newly repaired and strong base, which can withstand the load. The process of pouring differs little from the standard. You must first prepare the base, carefully examine it. If there are cracks or other defects, you should immediately repair them, replace the weak elements with new ones, remove all boards with traces of rot. After that, the solution is mixed in the proportions indicated by the manufacturer, poured from the far corner. Work should be in studded shoes, mix the mixture with a needle roller. It may be necessary to surface treatment with a special mop with a rubber tip. Self-leveling self-leveling mixes are an excellent option for giving the floor exactly those properties that are necessary. The surface is not only smooth, but also smooth, strong. It is great for laying any floor material. The process of the device of such a screed is not complicated, it is a filling of the mixture on the surface of the base, its distribution by a needle roller. The composition easily takes exactly the form that is required of it. The result is a smooth and smooth base.
