Self-leveling floors are beginning to gain increasing popularity due to the presence of a huge number of positive aspects of its use and operation. It is based on a polymer that is able to get into every pore of concrete in order to ultimately obtain a high-quality and strong coating. It can be used not only as a topcoat, but also as a subfloor. It all depends on the wishes and imagination.
Polymer self-leveling floor has a number of advantages, which are based on technical characteristics. Among these properties, it is worth highlighting the most basic of them:
- Strong structure. Due to this, the surface is not afraid of any external loads. Strength and toughness contribute to a longer service life of the self-leveling floor. Even with a constant load on it after 30-40 years after installation, it will be able to show all its original qualities.
- A huge number of shades, allowing you to choose the right color scheme. Any combination can be matched to a specific room design.
- High level of fire safety. In addition, it is used in completely different rooms with various indicators of humidity and temperature.
- During the cleaning process, any chemical agents can be used, since they are not terrible for the coating. Cleaning itself does not take much time and effort.
- Regardless of external factors, no harmful substances enter the environment. You can only encounter them when installing a self-leveling floor and until it dries.
- The subfloor made in this way is not conducive to the growth of mold and mildew. You can even say that this is all reduced to zero due to the components of the mixture for preparing the solution.
- After installation, no seams and irregularities remain on the surface. It becomes perfectly smooth, requiring no additional alignment.
- The rough finish is 100% sealed.
The adhesive properties are enhanced, which allows them to easily adhere to the floor being poured.
All these characteristics distinguish the cement self-leveling floor from other types. The scope is also more common. In addition to industrial facilities, such a base is perfect for warehouses and even residential premises. For each self-leveling floor, the characteristics will depend on the selected mixture.
Installation of the cover is very easy and without unnecessary knowledge. No expensive tools are used, which reduces overall costs. The main thing is that the device of polymer floors is in accordance with the instructions
The division of self-leveling floors can be carried out in many directions. The most basic of them is the content of the mixture used for work. Here you can note:
- Methyl methacrylate.
About them follows in more detail in order to learn about the properties and numerous positive points. It will not be superfluous to learn about the thickness of the future base. It is determined depending on the rough slab. When it is even and there are no noticeable pits, then a thin-layer floor is used, with a layer of 1 mm. Self-leveling options are more common. Their thickness is 4-5 mm. If the surface is so bad that high-quality leveling is required, then you already have to fill in the highly filled version.
The appearance of the future flooring will also play a role in choosing a specific mix option.
It can be matte or glossy. True, not all buyers are happy about the glossy surface, since very quickly it begins to scratch and loses all its beauty.
Any type of self-leveling floor can be additionally decorated with various elements that are simply laid on the base and filled with a transparent ready-made solution. So, when a person thinks about which self-leveling floor is better to level the floor, there is something to choose from and it all depends on the views, preferences and financial waste.
Among the main properties that an epoxy self-leveling floor has, it is worth highlighting not only strength, rigidity, but also fragility. With all this, they can be used at various temperatures, the fluctuation of which will be in the range from 0 to 50 degrees. But the fragility somewhat brings such a floor out of the overall positive flavor. This suggests that an effort should be made so that this self-leveling floor will base very well after stirring, since it is not entirely elastic. After drying and if the installation technology is not followed, cracks may even appear, spoiling the appearance.
If you need beauty and excellent surface design, then a polyurethane self-leveling floor is suitable, which is resistant to various mechanical influences from the outside. In addition, it is able to withstand any chemical substances, while remaining completely environmentally friendly and harmless to humans and others.
Such a self-leveling floor covering can withstand any frequent drops and increases in temperature for a long time. But this does not prevent them from being installed in office premises, as well as in apartments and private households. It is possible to fill not only small rooms, but also large areas, which is more specific for shopping centers.
A material such as cement for self-leveling floor gives the quality of moisture resistance. This differs it somewhat from the simple plaster version. This base is perfect for underfloor heating, which they began to equip more and more often.
When a self-leveling floor is installed, a cement screed is able to close numerous irregularities on the floor, even reaching a height of up to 8 cm. The most important thing is to choose the optimal composition of the mixture used for a particular case. If you do not have your own skills for choosing a future solution, it is better to contact a specialist.
A technical self-leveling floor is used to lay the sub-surface under the floor of a specific material. It cannot be used as a topcoat due to its low strength characteristics. But as a base layer, it fully performs all the assigned functions and tasks. The base layer thickness can vary from 10 to 80 mm.
The basis of the self-leveling floor, made in the middle layer in thickness, is cement. The strength immediately increases, but still the layer is not able to become the last layer. All these options are subsequently either covered with a suitable layer, or act as a base for flooring. In any case, the cement self-leveling floor dries up within 5-6 hours, after which you can start laying decorative floor elements.
Some believe that more water can be added to the concrete screed, and it will become a self-leveling floor. Initially and externally, this is exactly how it will look. But after drying, shortcomings will immediately climb - huge shrinkage, cracks and other negative consequences. In self-leveling floors, polymers are responsible for fluidity
The main difference between this option for finishing the floor covering is its low cost. By itself, gypsum does not have a high price level. They can cost even less than cement-based formulations. Almost all manufacturers provide a uniform composition of the mixture to fill the gypsum self-leveling floor. The only deviation is alpha gypsum, which is a high-strength material.
There may be a filler in the mixture in the form of fine quartz sand, which, in general, contributes to better surface spreading and plasticity. The latter property is important to avoid cracking after installation.
If you use special grades of gypsum in your work, you can get strength that exceeds the requirements of building codes. The strength will be up to 30 N / mm 2.
It is enough to add the required amount of liquid to the mixture for preparing the solution. It is very important to observe the proportions set by the manufacturer. Most often, they will be spelled out on the packaging of the finished mixture. After installation, you can move on the surface calmly and without fear after a few hours. Ved gypsum has a high drying rate.
The main disadvantage of a gypsum self-leveling floor is the low level of moisture resistance. In this case, it is better to choose tiles, linoleum among floor coverings. They will not let moisture through. But premises, like a bathroom or specially designated rooms for a boiler, should not be equipped in this way.
Timing can be adjusted to make repairs faster. But not everyone knows about which self-leveling floor to use in this situation. A methyl methacrylic coating will come to the rescue, which can dry in a matter of hours. Indicators of elasticity and strength remain at an average level. It can also be installed on the streets, operated in winter and cold seasons at subzero temperatures.
During the installation of such a coating, difficulties may arise associated with a pungent odor. If you do not stock up on the appropriate protective equipment, you can generally get poisoned. This smell lasts for several hours until the self-leveling floor is completely dry. After that, no nasty odors will remain in the room. It will not be superfluous to even ventilate the room where the work is being carried out while it dries.
With the development of technology, people try not to stand still, but constantly think about something new. One version of the self-leveling floor has the properties of elasticity and strength, the second is a version of the rough base, and the third generally gives an ideal appearance to the place that few people pay attention to. But I want to get everything in one, that is, buy a two-component self-leveling floor.
For example, there are epoxy and polyurethane based floors. In addition to the rigidity of the finished version of the base, plasticity is also inherent in it, which came from the polyurethane version. They can already be distributed and executed in parking lots, vehicle parking lots, at a train station in a waiting room, etc. That is, the area becomes much wider.
Gypsum-cement in most cases are used in warehouses, as well as a sub-floor for flooring. This is due to their rather low cost, but at the same time excellent qualities of leveling the base. Even a small layer will make the surface strong and reliable, which will last for at least 30 years. The main thing is that the technology of work performance and the sequence of actions of workers are fully observed here.
When a mixture is required that can withstand chemical compounds, oils, fats, not only cold, but also hot water, then a cement-acrylic version of the self-leveling floor is suitable. Here, two components such as quartz filler and polyacrylic polymer are mixed. It is they who give the finished solution such qualities. Among the features of such a coating is the surface roughness, which does not allow slipping even on a wet floor. The area of use is pool floors, bathrooms, showers and similar objects.
There is also a two-component polyurethane self-leveling floor, which gives the second component its properties and characteristics. The most important of them are plasticity and good fluidity, which excludes the appearance of cracks on the surface after drying.
In order to correctly, efficiently and competently carry out the device of self-leveling polymer floors, one should adhere to certain norms and requirements, the sequence of work. It will be enough to do everything step by step:
- Complete cleaning of the surface from foreign objects, any dirt and dust. When work is carried out on the street, even asphalt is removed, which can have a negative impact on the self-leveling floor later.
- Special building mixtures are used to eliminate unevenness and roughness.
In certain situations, the surface under the self-leveling floor is primed.
- A container is selected corresponding to the size, in which all the necessary components for the finishing coating or technical floor are mixed, including also possible additives, components.
- Fill. The solution should be poured at the highest point in the room and then evenly distributed over the surface. In this case, the laser level will help, which will set all the parameters. Rolling is carried out using a needle roller. It is he who will allow you to adjust the layer thickness.
- If desired, particles and decorative elements can be applied to only the poured solution.
- If this is a topcoat and not a subfloor for laying the flooring, then after 10-12 hours the surface should be varnished.
A day will be enough to dry any type of self-leveling floor, but it will be able to dry completely after a week. The only exception is methyl methacrylate options, which can dry until ready one day after installation.
It is better not to use self-leveling floors as a leveling screed. On any irregularities, such a mixture will harden and form a reminder of shells, seals. It will only make things worse. In addition, dismantling the self-leveling floor is very problematic and costly.
The mixture used in the work on the self-leveling floor is very important. It may include various components and additives that contribute to the manifestation of certain properties and qualities of the finished solution. When a self-leveling floor is performed, the consumption will depend on various factors, which include not only the base itself, but also the slope over the area of the room. It is impossible to deviate from the minimum indicators of the thickness of the finished solution for the finishing coat. This data should be recorded at the lowest point. Often, the minimum parameters are prescribed directly by the manufacturers of the mixture on the packaging.
If finances allow you to buy additional bags of ready-mix above the amount due, this should be done. If you do not buy the missing amount in time and do not fill the self-leveling floor, then the costs will be much more than an extra bag. In short, the topcoat will be damaged and it will have to be done again.
Among the mixtures for self-leveling floors, Scorline T45 is distinguished by its fast drying after installation. Its minimum layer cannot be less than 2 mm, but the maximum reaches 10 cm. The mixture is applied under any floor covering, including when installing underfloor heating.
For a self-leveling floor, fast-hardening coreite scorline is packed in separate bags of 20 kg. If the average thickness select indoors 1 cm, per m 2 will take about 13 kg of dry mix. For each kilogram, it will be sufficient to pour 0.35 liters of water. These indicators are optimal and most applicable in work.
When choosing a specific option for a self-leveling floor, it is worth proceeding from where it will be located, as well as what amounts are allocated for it. After all, you can make a rough version for flooring, or it can also act as a topcoat, decorated with various decorative elements. At the same time, it is important to consider the choice of a mixture for a self-leveling floor, which is prepared in strict proportion with all components and water. The most important thing is that the end result is a really flat surface that can last for several decades.
