Leveling the floor with a self-leveling compound: screed and drying time for bulk, better gypsum and cement

Make floor leveling with a self-leveling mixture can be done on your own without recourse to specialists It's completely possible to make the leveling of the floor with a self-leveling mix by yourself without the help of specialists The most important part in the apartment is the floor. This surface is constantly exposed to physical pressure, as well as pollution. Therefore, it is so important that all the elements that make up the floor are strong and strong. However, for the service life and strength of the finishing materials, the curvature of the substrate may be adversely affected. Most of the finishing coatings require a perfectly flat base, this effect can be achieved by using a special self-leveling compound. With work with such a composition even a novice in construction can cope.

A self-leveling compound is a real find for those who have xThe score is to make a floor screed with your own hands. Such formulations are sufficiently liquid, so they easily spread across the floor, filling all the pits and cavities. Liquid leveler has all the properties of traditional screeds, plus it has some additional advantages.

The main advantage of a self-leveling mixture is that it dries very quickly The main advantage of the self-leveling compound is that it dries very quickly

Advantages of the self-leveling screed:

  1. Such mixtures dries very quickly. You will be able to walk on the base after the screed is filled, after 4-5 hours.
  2. Unlike traditional screeds, the filling leveling mixture contains very fine dry particles. Due to this feature, the surface covered with such a composition becomes smooth and even.
  3. Shrinkage of such a floor is practically impossible.
  4. The maximum height of the filling floor is 5 cm. This alignment is suitable for rooms with low ceilings.
  5. Pouring this mixture is so simple and understandable process that it can be handled without having even minimal knowledge in the construction sector.

Self-leveling agents will help you quickly and efficiently make a floor screed. The main thing is to follow the instructions on the package exactly when you will dilute the mixture.

Kinds of self-leveling floor screed

Self-leveling compound, of course, will make it easier for you to tighten the floor, but do not expect any miracles from it. Simply fill the screed and wait for the result only if there are only small irregularities on the floor surface. In other cases, you may need to apply several types of self-leveling screeds.

There are several types of self-leveling compounds, which should be chosen taking into account the location where they will be applied The self-leveling screed is used when the floor is in critical condition. This composition is filled with a fairly thick layer( about 5-7 cm).

  • The mixture is used to remove defects in certain parts of the floor. Such a tool will perfectly close small pits and cracks.
  • The final liquid leveling compound is used for the final preparation of the floor for the installation of the decorative coating. This composition is applied in a layer of 0.2-1 cm. After drying the screed, you will get a perfectly flat and smooth floor.
  • Each kind of screed is used in its specific case. Sometimes it happens that you have to combine several layers of different means on the same floor. Often together use a roughing and finishing screed. Also a combination is possible, such as a local and final mix.

    If you do not want to use a liquid self-leveling mixture for the floor, then you should pay attention to the dry screed "Knauf superpol", which is done by laying on the expanded clay filler elements from GVL.

    Self-leveling compound can be used for almost any substrate. Exceptions are only wooden floors. However, some masters assert that a strong wooden base can be leveled by the finish line, if you first put a film under it.

    Which filler floor is better, plaster or cement

    The self-leveling mixture consists of a large number of different substances that give it plasticity and the ability to spread quickly and evenly. However, the main elements in such solutions can be only two substances, namely: gypsum or cement.

    Good qualities are characterized by both gypsum and cement floors Good qualities characterized by both gypsum and cement floors

    Many people are worried about the question: "What is better, cement or gypsum composition?".There is no unequivocal answer! Each remedy is good in its own way and is applied in a particular case.

    The gypsum mixture is used when it is necessary to fill a sufficiently large layer of screed. The height of such a filling can reach 10 cm. Gypsum is an environmentally friendly and harmless material that will provide additional insulation to the room. Especially good neighbor, gypsum composition is for wooden coatings, for example, parquet or sheet pile. With this symbiosis, the gypsum will not allow cracking and rotting the finish of the floor. In case of a sudden increase in humidity, the screed absorbs water from the tree, and if necessary returns it back.

    For premises with a high level of humidity, for example a bathroom or kitchen, a gypsum self-leveling screed should not be used. It will be appropriate to more unpretentious cement. The layer of such a mixture can reach from 5-30 cm( depending on the curvature of the floor).The cement equalizer also includes sand and fine-grained expanded clay.

    There is also a polyurethane filling floor, but it is not used for leveling the substrate, but for finishing it.

    Both types of floor leveling compositions are good in their own way. Gypsum composition is more often used in European countries, and concrete is a favorite on the Russian construction market.

    How to align the floor with a self-leveling compound

    It's quite difficult to level the floor with traditional compounds, but with self-leveling mixtures everyone can handle it. The main thing is to properly dilute the composition and step by step to perform all the activities associated with pouring such a screed.

    Before you proceed to pouring, you must first thoroughly clean the surface of the floor, remove the old covered Before proceeding to priming, you must first thoroughly clean the floor surface, remove the old coated

    Floor leveling technology in bulk self-leveling mixtures:

    1. At the first stage, the floor is prepared. All garbage and dust are removed from it, large pits are poured with cement mortar, the surface is primed. The primer is necessary in order for the filler equalizer to grow better and bond with the base.
    2. The second step is to mix the mixture. The proportions of the composition should be clearly observed, they are usually indicated by the manufacturer on the package. To mix the correct solution, you need to pour in the already poured water you need a mixture. Only properly prepared liquid screed perfectly level the floors.
    3. After the mixture is mixed, it can be poured on the substrate. In this case, the screed should not be hot, the optimum temperature for such a means is 25 degrees. To make a flat floor, it is necessary to apply markings on the walls, to the level of which the leveling mixture should reach. The layer of the equalizer should not be thinner than 0.5 cm. It is more convenient to pour a mixture of strips, while the second strip is important to pour before solidifying the first. To remove unnecessary air bubbles, you need to use a needle roller.

    To make a high-quality floor leveling, you must follow all the manufacturer's recommendations exactly. Deviations from the norm when mixing the mixture can give a completely unpredictable result.

    Pay attention to the filling floor "Starateli".This manufacturer is recommended by many professionals.

    It is also important to understand that the self-leveling mixture, although it can be distributed on its own, needs to be slightly aided by a special needle roller. Such work will not only ensure a more even distribution of the composition, but also will remove unnecessary air bubbles.

    The shrinkage of these mixtures practically does not occur. Therefore, you can be sure that the layer you fill will not change its thickness.

    Drying time of the bulk floor

    In order to continue the repair work without risking spoiling the floor, you need to know how much the self-leveling mixture dries. If you proceed to the finish of the floor, until the screed is completely dry, then, most likely, you have to redo everything anew.

    Typically, the filler floor dries within two to three weeks As a rule, the flooring dries within two to three weeks.

    Despite the fact that you can finish the finished floor after only two weeks, you can walk it in a couple of days.

    The drying time of self-leveling mixtures can vary within two to three weeks. Everything depends on the composition of the mixtures and on their producers.
