Which self-leveling floor leveler is better. The service life and appearance of the floor largely depends on how smooth the surface is under it. Before proceeding with the restoration work, pay due attention to the repair of the slabs and high-quality leveling of the floor. A self-leveling floor leveler will help you cope with this task.
The base is poured with quick-drying solutions not only during major repairs and construction, but also during cosmetic repairs of the premises.
This article will help you learn how to choose the right leveling compound and how to apply it correctly.
Self-leveling self-leveling floor is used for screed and eliminate defects. In addition, it performs the following functions:
Interestingly that self-leveling floor leveler is easy to spread over the area of the base, and is characterized by a fast curing time. After 5-6 hours, you can walk on this floor.
Floor levelers are produced in bags, dry. They differ among themselves in composition (plaster, cement), and purpose (corrective, starting and finishing).
To cope with the installation of a screed from 2 to 5 cm, the cement composition that can be used for any type is ideal for you premises and purposes (universal). Sometimes microfibers are added to the mix to strengthen the concrete base and replace the reinforcement.
Gypsum mixtures are perfect for use in dry rooms, since the material itself absorbs moisture well and, if it is excessive, begins to swell.
With an increase in the volume of the base, the finishing flooring will begin to deteriorate and after a while may even lead to deformation of the walls. As an advantage, you can name the high strength of the walls and the ductility of the screed, which will not be more than 1 cm thick.
Important: If you want to get a stronger and more durable base, you will need add plasticizers to the finished composition.
Depending on where the mixtures will be used, they are divided into:
Thanks to the starter coat, you will be able to create a rough surface, which will then need to be covered with a finishing solution.
Interestingly, that for the treatment of rooms with high levels of humidity, certain moisture-resistant formulations are used, which contain special polymer components.
Although a self-leveling floor is several times more expensive than simple cement mortars, they have many advantages:
Please note, that if you urgently need to level the floor and start using it, then ideally use pride for the self-leveling floor. If on the label you find a particle size designation of 1.5 mm, then this composition is used only for ordinary screed.
A self-leveling floor leveler is considered as such if the size of its fraction is less than 0.
To save on the purchase of this building material, you need to clearly define for yourself:
Hint: The finishing leveler is much more expensive than usual, so use only starter mix for roughing.
|Cement||Cures slightly longer than similar solutions are suitable for use in rooms with high humidity levels.|
|Gypsum||High drying speed, not suitable for rooms with high humidity levels.|
|polyurethane||A plastic base is achieved, which will not crack under temperature extremes, vibrations and shock loads. It is used as a finishing layer, but before use, the surface should be well prepared|
|Cement-polyurethane||When using such a solution, you will get a durable, strong and stable base with respect to stress and abrasion|
|Cement-acrylic||Created on the basis of polymers, cement and acrylates, requires experience in pouring, you can make a high fill of the screed and not worry about cracking, create a strong, even and frost-resistant surface|
|Methyl methaacrylate (MMA)|| Such mixtures are made on based on methacrylic acid and methyl ester.
Distinctive features - fast solidification, high strength and resistance to moisture, can be used for places with high traffic (for example, at an industrial facility). In a liquid form, it is toxic, flammable, but after hardening it loses these properties.
|Epoxy||Created on the basis of epoxy resins with hardeners and plasticizers to achieve a transparent, durable and smooth surface. Can be used to create a 3D effect floor, there are formulations with anti-slip additives.|
|Self-leveling floor levelers|| To create the base layer.
|Those containing many fillers||I use it when leveling the base and creating a decorative layer.|
|finishing||Only for the top layer.|
Please note, that when choosing a mixture for a self-leveling floor in an unheated room, you should make a choice in favor of frost-resistant compounds. So, with a material consumption of a layer height of 0.1 cm, it will be from 800 to 2000 grams.
When filling a self-leveling leveler requires careful surface preparation. Depending on what type of topcoat is used and in what condition the base is, we will select a mixture for starting and finishing.
The appearance and durability directly depends on how well the preparation is made, so you should approach this matter very responsibly.
Attention! Priming the surface is very important before each leveling application. It will increase the strength of the compound and provide better adhesion.
If the thickness of the leveling is more than 1 cm or in several layers, outline the height of the screed.
Correctly carry out the markup as follows:
The self-leveling floor leveler should be poured no less than 6 hours after applying the primer layer. To obtain a high-quality and homogeneous solution, the dry mixture should be poured into water, which will be at room temperature. Dilute 25 kg of the mixture in 6 liters of water. Since with manual kneading you will not be able to make it homogeneous, you should prepare a drill with a nozzle or a construction mixer in advance.
The components are mixed in 2 passes:
Important: Prepare such a volume of solution that you can work out in 35-50 minutes, since with a larger amount it will begin to dry out and will no longer be suitable for creation self-leveling floor.
Begin pouring from the far corner between the beacons (ie stripes) and then the solution is distributed over the area. If you notice that voids have formed, add a little more mortar to this place and smooth it again, as a rule, you should drive it like on rails.
If more than one coat is required, allow each coat to dry for at least 24 hours.
After the mortar begins to set, fill the space with the mixture and level.
Important: In order to avoid uneven drying and the appearance of cracks on the surface, protect the room from drafts, artificial heating and sunlight.
The finishing self-leveling floor leveler is used to obtain a perfectly flat surface. When pouring on such a floor, walk in studded paint shoes.
The surface on which the mortar will be applied must be even and have at least 2 coats of primer.
To prevent the mixture from leaking to neighbors, it is recommended to use a waterproofing material.The solution must be liquid, which means that you do not need beacons - it will be applied in one layer and will spread perfectly over the surface.
The area of the room should be divided into zones, and each of these zones should be filled in 15 minutes. The solution should be poured from the far corner, after which it is leveled with a rule. We fill the plots in one run to the desired height, and then go through the solution with a needle roller to remove air bubbles.
The solution with polymers will harden in half an hour.
Done! It remains only to protect the surface during drying from abrupt drying, drafts and mechanical damage. Polymer topcoat is applied not only for quality coverage but also for 3D images. If you decide to make this a reality, then remember that the layer of solution should not be less than 0.3-0.
4 cm. Thanks to the unique composition, you can create an original volumetric drawing.
