In many apartments, the base for the floor isslabs, which, as a rule, have irregularities. Improving your sex is tricky. But today there are new building technologies that greatly simplify the task - how quickly. The conversation will focus on self-leveling self-leveling floors. If you're not sure if your room needs floor leveling, take some measurements. You need to take a long ruler (1 m) and, applying it to the floor, check if there is a gap between the ruler and the floor. If there is a gap greater than 2 mm, alignment must be done. You can also check the floor using a building level. 
The color of the floor must correspond to the interior of the room.
Variety of mixtures for floor leveling
Before proceeding to the question, how to levelfloor, let's talk about what it can do. The composition for leveling the floor can be made independently, mixing cement with sand. In the current world, new technologies have emerged that use different mixtures that have not only binding properties, but also thermal insulation and soundproofing. Aligning the floor with the use of such mixtures greatly facilitates the work. 
Preparation for leveling the floor. There are many such solutions available. In general, they consist of quartz sand, cement, modifying additives and even pigments. There are special compositions for leveling the concrete and wooden floor. They differ strength, smoothness, a layer of pouring and are divided into basic and finishing. The latter is really a full deck of bulk polymer or epoxy. And the base mixture is just the base, which needs additional floor covering. Of all the mixtures, the builders are marking another type - thick-layered. They are used to fill depressions and cracks, as well as to level a large bumpy floor. In addition, there are mixtures for repair - to eliminate major flaws, grounding - for the installation of concrete floors, sealing - for sealing slits and holes. If you want to speed up the process of solidification of the mixture and simultaneously improve its properties, you can buy a special plasticizer - an active additive, which is introduced into mortars. The main thing - to properly knead the solution in order to level the floor in the room. It is necessary to prepare a capacity of 20 liters for the mixture. Then, prepare water at a rate of 1 liter per 5 kg of dry mixture. To get a good homogeneous solution, you need to dry the composition to water, and not vice versa. Then drill with a special nozzle to mix the mixture for 5-7 minutes. After this, take a break for 1-2 minutes and mix again. Back to contents</a>

Scheme of leveling the wooden floor. If the floors are made of wood, you first need to check their strength. Trowel and sagging boards need to be replaced. To remove the protuberances and any unevenness, the floor can be treated with a grinder. It is not necessary to take the sheets of particle board to level the wooden floor. Because of the release during the operation of formaldehyde, they are harmful to human health. After repair, the floor of the boards usually does not require special preparation. If there are irregularities on it, you can additionally lay plywood sheets. If the floor of the tree is badly spoiled or rotten, you do not need to invent something. It is better to get rid of old boards and make a concrete screed. When the screed is made, the floor level rises. Therefore, you need to change the location of the doors. To avoid this, you must first calculate the height of the screed for free closing the doors.

On the smoothed concrete floor in the room after 3 days you can lay ceramic tiles, and laminate, linoleum, parquet or carpet - a week later. Back to contents</a>
Align the floor with your own hands
The procedure for leveling the floor seems verydifficult, accessible only to specialists. But knowing some rules for leveling the floor, you can do these works yourself. It is enough to get some knowledge about the necessary building materials, tools and have a desire. All you need to do is: put the beacons for the screed and how to prepare the solution. 
Tools for floor screed: beacons, pelvis, spatula, level, tape measure, roller, cutter. Still need to prepare tools:
- rule;
- Needle roller with long handle;
- level;
- a drill with a nozzle for stirring the solution;
- Any capacity (bucket) for mixing the mixture.
The speed of leveling the floor depends on the size andthe number of surface irregularities. For small unevennesses on the concrete floor - if the bending is 1-2 cm, you can apply self-leveling floors. So level the floor faster than making a screed. With large irregularities, use a self-leveling mixture is not worth it, it will be too expensive, and will dry for a long time. With floor differences of up to 5 mm and if you plan to lay the laminate, you can simply lay a film for moisture insulation and a soft adherent. It will be the fastest. 
Landmark for leveling the floor. With a big bump, you must set the laser level to the highest point of the floor and draw a line of alignment that will serve as a guide for pouring the solution. In the absence of a laser level, another method can be used. It consists in the following: find the highest point on the floor and mark it up on the wall 5-6 cm. Then attach the rail parallel to the floor, level it and level it with a mark on the opposite wall. So to put labels on all border of a room. By marking up the ropes, we get a plane - a landmark for alignment. All work related to leveling the floor, it is better to do together, because the solution needs to be spent within half an hour, and alone it will be difficult to do. One worker prepares the mixture, and the other at this time the ready solution pours the floor, starting work from the far corner of the room. Each next batch of the poured mixture must be rolled with a needle roller to improve flow and remove air bubbles. And so until the completion of the work. Each time before use, the solution should be stirred. Fulfilling these recommendations, you can work with an assistant to do expensive work on leveling the floor and save money. No unusual abilities are required for this, only physical strength and the desire to do this work are needed.
