Self-leveling floors are becoming increasingly popular due to their excellent quality and the provision of strength characteristics during operation. They are able to serve for a long time without repair and restoration. But for this, first of all, the technology of pouring the prepared solution must be observed. In addition, the choice of specific materials for work will also play a significant role, among which the mesh for the floor screed stands out. A competent choice of its specific type will affect the final result, whether it is a topcoat or a base layer of a self-leveling floor.
Types of meshes
If it becomes necessary to strengthen the base, a reinforced mesh should be used for floor screed. The strength of the coating will be much better. The most commonly used metal mesh. But technology does not stand still. Now there is already an alternative to it - a polymer version that can satisfy any screed. There are two options for the grid arrangement:
Moreover, their cells are different in size, depending on the purpose. It can be 10 * 10 or, for example, 15 * 15 mm. In addition to the self-leveling floor, such nets are applicable for fencing on sports grounds. In addition to such a function as strengthening, the reinforcing mesh for the floor screed helps protect against any kind of mechanical impact from the outside.
If a floor screed mesh is used in the work, the coating will withstand higher loads than those established by the manufacturer. And this is all despite the fact that the appearance will remain exactly the same attractive. Buying a mesh will reduce costs, in general, when installing a self-leveling floor. Its cost is insignificant and can be used when performing various types of work. Suitable not only for a new building, an apartment in an apartment building or in a private household.
In order for the quality of the floor pouring to be at a height, the mesh must be laid before applying the mortar. You can also apply a mesh if the floor screed is cracked. But it has its own characteristics and subtleties that should be adhered to.
When choosing a mesh for a self-leveling floor, you should focus on some indicators:
- The size of the cells.
- Production method (welded, knitted).
It is the last point that is mainly selected when installing a self-leveling floor. It also determines the purpose of the product during the installation process. After all, no one will take a screed with a thick metal or polymer element to create a high screed layer. This is only applicable for significant differences in room height.
For an apartment, the mesh thickness will be excellent with a minimum indicator of 3-4 mm. The coating will become durable and will be able to withstand any stress. The concrete layer can be up to 40-50 mm. Thicker mesh reinforcement options are suitable for warehouses, shops, etc. But at the same time, the screed layer will significantly increase up to 150 mm. In this case, the screed will be supplemented with insulation, layers of sound and waterproofing. This suggests that the mesh for reinforcing the floor screed has a huge purpose.
As for the underfloor heating device, the situation is somewhat different. The underfloor heating screed mesh can be placed under the entire system. This is necessary so that pipes and elements can be tightly fixed and held in one position after pouring. In other cases, everything will depend on the required surface strength and the requirements. The quality of the work will avoid cracks in the underfloor heating screed. But especially novice builders may face such a problem when the floor screed is cracked. We'll have to carry out a complex of resuscitation measures.
Applying the mesh
Reinforcement of the underfloor heating screed is necessary in those rooms where there is a sufficient number of loads. Walk-through rooms cannot do without it. Strengthening must be done at the proper level so that later there are no problems with damage to the underfloor heating system.
By applying reinforcement, the screed will be able to withstand vibration and dynamic loads.
If you perform a reinforcing floor screed, then practically no movement (especially manifested in new buildings) of building elements during operation will be terrible.
Strengthening a concrete screed can be done in several ways:
- Using mesh for reinforcement.
- Creating a thicker layer.
The screed is fastened with dowels to the slab. In no case should it be laid on the base. That is, the net should "float" in the air. This even in some cases allows you to avoid cracks in the floor screed in the future. No heat load or mechanical stress is terrible.

4. Self-leveling floor.
If cracks appear on the screed after pouring, then an appropriate mesh will have to be used for repair work. Such problems arise when the temperature regimes are violated when mixing the solution and subsequent pouring.
The technology of laying a warm floor, as well as pouring a self-leveling floor, must be observed at all stages. There should be no exceptions. Otherwise, problems may arise that will have to be solved, spending energy and money. This is especially true when pouring a self-leveling floor onto a warm floor, when the entire system should not function. If the warm floor is activated prematurely, then the drying of the solution will not occur evenly and not qualitatively. As a result, defects will begin to appear, namely cracks in the underfloor heating screed.
The underfloor heating screed also cracks for numerous other reasons related to the pouring procedure.
Not everyone knows what to do if cracks appear in the floor screed, what to do and who to contact. If it is not possible to restore it on your own, then it is best to pay a certain amount to specialists.
To eliminate such negative manifestations of violations of the instructions, you will need a grid for filling the floor. Everything will depend on the thickness of the repair. If a new layer of self-leveling floor is arranged on top, then it is best to take into work a grid for putty facades. It is insignificant in thickness and has excellent qualities and characteristics.
Repair of screed filling should be carried out in the following sequence:
Special glue is applied to the places with the cracks that have appeared. The most popular is tile adhesive, which has excellent bonding properties. To perform the work, we use a trowel with teeth. The adhesive must be applied evenly over the entire surface.
- The mesh is laid, and all the glue released is leveled over the surface. The layer turns out to be insignificant, but still more is used in the subsequent laying of the floor covering. But before laying, you should wait a certain time until it dries completely.
Cracks in the underfloor heating screed may appear in the finish, and not many know what to do in such a situation. Here it is best to arrange an additional layer of self-leveling floor. The surface must be primed without fail to increase the adhesion level. Significant defects are "embroidered", also treated with a primer.
The most basic question that arises during repairs is how to fill the cracks in the floor? For this, a repair compound is used. But it is not uncommon for the mix to be mixed for a self-leveling floor. It all depends on the thickness of the cracks and the conditions. They can even be sealed with tile adhesive. But in such a situation, you will have to lay the flooring, since it will not be possible to apply it under the topcoat.
If the underfloor heating screed has cracked, then the most important thing is to check the entire screed for coils. Dull sounds may appear when tapped, indicating errors in the performance of work. Most likely, you will have to disassemble the screed to the ground in order to eliminate defects. True, after screed the floor, this will be problematic.
Having studied all the subtleties, there should be no questions about why the floor screed cracked after pouring. This suggests that the technology of the screed device and the self-leveling floor was not followed. This applies not only to surface preparation, but also to mixing the solution, observing the proportions when adding water. To prevent the underfloor heating screed from cracking, the entire system must be turned off until the surface is completely dry. It may take 7-10 days.
Filling of screed cracks must be carried out with high quality, using appropriate mixtures for the work. At the same time, it is important to observe the nuances of surface preparation, elimination of debris and dust, using certain equipment.
Mesh for self-leveling floor can be used not only as a reinforcing agent, to increase the strength of the surface, but also to carry out restoration in the event of damage.
Semi-dry screed in winter, at low temperatures, the choice of a specific thickness of the subfloor, the order of drying and the associated time and temperature range. A huge nuance of arranging a semi-dry screed is that there is no adhesion with overlap, and the base itself is a polyethylene film that acts as a waterproofing layer. For this reason, a minimum thickness of 40 mm
