Recently, in the repair of many apartmentsthe townspeople are trying to change the flooring in the more modern such as laminate, parquet or if it is a bathroom, then imported floor tiles. However, all these types of coatings are very demanding to the base on which you plan to perform liked the cover. Laminate flooring and ceramic tiles should be laid on a sufficiently flat surface. If the base is cement or concrete floor, then surely it is far from the surface requirements for laying laminate.
Now this problem is easily solved by usingthe technology of so-called self-leveling floor, it is called self-leveling. These floors are performed both in residential construction and industrial facilities, as well as in offices and other premises. The only difference is the composition of the material used.
In the building materials market has a largea variety of materials for self-leveling floors, as the eminent firms, and domestic producers. In practice, such a floor is a dry mixture, packed in bags of 25 kg. We can only stir the mixture with water can be poured and the floor. Each bag printed instructions for the preparation of the solution and filling the floor. It is important to strictly adhere to the proportion of water and powder, it affects not only the drying time, but also the subsequent strength of the self-leveling floor. And it is worth noting if you are not familiar with such works, it is necessary to give preference to self-leveling floor of the most famous brands such as Vetonit 3000 or the equivalent. On the material cost savings it is very risky, as many lesser-known manufacturers of products is poor. The floor covering composition includes a mixture of gypsum and cement, the composition for industrial floors objects is characterized in that it includes a polyurethane, epoxy resin and other synthetic components.
You will also need a deep primerpenetration for priming the surface prior to filling the floor. For this purpose, suitable Ceresit CT 17. Also required damper tape length equal to the perimeter of the room.
The composition of self-leveling floors are divided into mineral and polymer. Currently all existing floors are divided into five groups:
- epoxy binders;
- methyl methacrylate;
- cement and acrylic;
- Self-leveling floors 3D.
Mineral floors serve as the basis for floorcoatings and are used in residential premises. Polymer floors act as an independent finished appearance of the coating and are used in the trade and exhibition halls and in various social and cultural institutions. We should also be said about liquid floors 3D. This is perhaps the most attractive floor, gaining a lot of popularity today. It consists of a lower layer in a pattern or a photograph, and a transparent top layer, which serves as a protective coating. It is not just an independent floor covering, and the whole work of art.
To perform work on pouring the self-leveling floor will need a list of necessary tools, the specialists it is mandatory:
- plastic container or bucket of 20 liters for mixing the solution;
- electric drill, hammer drill or mixer with attachments;
- laser level;
- roller for priming;
- Needle roller with a handle;
- squeegee or trowel for leveling mix on the floor;
- a vacuum cleaner;
- tips on shoes with spikes, so you can go without leaving a trace;
- Bulgarian diamond nozzle to remove sagging concrete;
- measuring tape and a marker;
- ordinary trowel;
- building level.
This is a list of necessary tools, in each case, you may need something extra.
Before starting the work necessary to preparebase for self-leveling floor. If the top is an old plate, and on it the remains of the solution, the old ceramic tile or old paint, all that is necessary to scrape off, disassemble and clean. For this fit a hammer, a trowel or a Bulgarian with a special nozzle in the form of a cup with a diamond-edged. Then it is necessary to sweep and remove dust with a vacuum cleaner. Of course, you need to work indoors when it is released from furniture and anything that might interfere with high-quality casting floor. If there is a gap between the wall and the floor, they need to be repaired with cement mortar. On the perimeter of the room damper is glued tape. And in the doorway as the nut, preventing leakage of the solution, you can set the profile of the drywall anchors securing it to the floor.
One of the most important moments in the deviceFloor inlet - definition zero and, accordingly, the thickness of the floor and calculating, based on this, and the calculated flow rate value of the materials. For this purpose better than any other suitable laser level or as it is called, laser level. It provides an opportunity to determine the highest point of the floor in the room. Using it, we will find all the other marks in the room. In practice, this is done so. It poses the laser level on a tripod at a height of about one meter and turn on the sight of the horizontal plane. Then with the help of all the roulette Gaugeable gender point and select the highest. This will be the zero point.
Then proceed as follows: in that the highest point of 3.2 mm to provide self-leveling floor thickness. Make a pattern: first, measure the length of roulette from the laser beam to the highest point, consuming 2-3 mm and transfer this size on the rail, noting her risk. This will be the template. Now, with his mark out the level of self-leveling floor along the walls. Combining the risk from the laser beam along the lower edge of wall slats do label. Then all these tags are interconnected by means of a spirit level. Incised line indicates the level to which you want to fill in self-leveling floor.
How to fill in a self-leveling floor can be found in the video:
In the video, a detailed account of the whole sequence of works on filling the inlet floor, surface preparation before pouring and how to perform marking with a laser.
Before filling the floor the entire surface of the concretethe base must be primed, preferably 2 times. The primer is required so that the moisture of the filling is not absorbed in the floor concrete foundation, and the hardening process takes place uniformly throughout the thickness of the floor of the inlet, so as to increase the joint strength and the base floor. The range of primers is currently a very large both in price and quality. It should give an example of a deep penetrating primer Ceresit CT17, which is time-tested and is in the middle price range.
After you have made all the preparationsoperation, the damper is installed tape, defined level of the floor and made a primer, you can proceed to the main stage - filling self-leveling floor compound.
The bucket poured the contents of a bag orhis half, if not allow the volume and is filled with a certain amount of cold water, according to the manufacturer's instructions inlet floor. With the mixer or attachments made thorough stirring the mixture until smooth. After a few minutes necessary to once again stir until completely smooth. It is necessary to strictly keep in mind that the finished mixture should be consumed within 30-40 minutes. The first bucket is poured into the far corner of the room evenly along the wall. At the same time preparing for the next batch, the entire process should be continuous.
After leveling the first portion vianotched trowel, next poured in the same way the second bucket. Care should be taken that the mixture spreading evenly across the floor. After filling the entire area you need to walk a few times a spiked roller to remove any air bubbles. Shoes in this case should be spiked. After careful leveling roller and achieving top-level self-leveling floor required tags, sex is considered to be flooded. Now we need to wait for about 4 hours. It is necessary to make sure that the room was not draft and falling to the floor to direct sunlight. We reviewed the process of how to fill in self-leveling floor leveling.
Upon completion of 4:00 can be analyzedperformed floor. With the construction level of control is made of the floor surface. If all milestones are correct, the two-meter level will not detect a single lumen. Will only cut knife damping tape. A week later, it will be possible to start nastilke laminate or parquet.
