When buying your own home in a new apartment, everyone wants to have almost ideal premises with all the decoration. But this happens very rarely. Often, the eye falls first of all on the base of the floor, where the flooring is subsequently laid. Concrete floors cannot please with the flatness and strength of the surface, which leads to the need for high-quality repairs. Of course, you can do without this, but in the future all defects will manifest themselves, and the money spent will be much more.
The need for repair
Repair will be needed in the new building almost immediately.
It is unlikely that the quality of the screed will be fulfilled at a decent level. The emerging cracks, potholes from the tool and other external influences will not allow the floor covering to be laid with high quality. In addition, due to poor filling of the solution, increased dustiness appears, which will only increase.
It is worth noting that at the initial stage it is best to repair individual sections of the concrete floor than to dismantle the floor covering over time and arrange a major one. To level the floor in a new building, you will have to buy the necessary material and tools, which will depend on the specific type of performance.
When you need to know how to level the floor in a new building, then first you should think about choosing a specific screed option. Much will depend on the choice of flooring, its specific type. The choice of the screed will also be influenced by the room itself, the condition of the floor. The technology must fully correspond to the desired result in the end. A rough floor screed in an apartment can be performed according to the following options:
- Application of specialized mixtures. They must be sealed with water prior to pouring onto the sub-floor. Thus, a cement-sand mixture is performed for floor screed.
- Adjustable floors. Lags are used here to level the floor in a new building. Logs can be made from plywood sheets or other sheet materials. The height of their location will depend on the quality and evenness of the base.
Dry screeds in the form of special slabs.
Before pouring the mortar on the base of the floor in a new building or carrying out repair work on a separate area, you should make every effort to prepare it for work. All existing debris with dust is removed, for which you can use a construction vacuum cleaner. Existing cracks are “embroidered”, expanding for better adhesion.
Attention should be paid to the presence of reinforcement in the floor slabs or poured screed. With protruding areas, it must be cleaned in order to get rid of metal corrosion, if any. Subsequently, this will allow the floor to be used with the coating for a long time.
Before the sub-floor is laid, you can try to repair individual areas that remained damaged before the delivery of the living space in the new building. In addition, they begin to appear in case of violation of the technology itself for performing a concrete floor screed. In this case, a rectangular cut with a depth of no more than 20 mm is made around the perimeter of the existing surface damage.
Here, a grinder equipped with a diamond disc is perfect as a tool. The damaged areas of the screed must be completely removed before the next step.
After removing debris and dust, the pothole along with the resulting depression is filled with a solution. But this one should be specialized for repairs, which can be purchased at any hardware store. Leveling the level relative to the rest of the floor is carried out by the rule. For complete polymerization of the composition, a specified time must pass. It can most often be found on the packaging for the working mixture. After this period of time, the strength will become the highest. You can start sanding the surface. The best option in each case is the use of specialized equipment, which will significantly reduce the time for repairing floors in a new building.
Getting rid of cracks
As soon as we come to a new home and notice even minor cracks on the base of the concrete floor, we should immediately start repairing the sub floor. This will avoid the appearance of large damage in the remaining areas. In addition, not only moisture can get inside, but also dust, which causes the destruction of the concrete composition.
Do not install any kind of floor covering on a base with existing cracks. In the future, not only the screed itself will be destroyed, but also the floor covering structure.
The beginning of work on the removal of cracks should begin with their jointing. Depending on the size of the crack, the cut itself will vary from 20 to 50 mm. All edges and the crack itself must be cleaned of debris and dirt. It will not be superfluous to prime the surface with epoxy or polyurethane based compounds.
This will increase the level of adhesion of the castable repair compound.
After filling the crack with the mixture, time is allowed for the mortar layer to shrink. Once frozen, the solution is covered with another layer. As a result, all that remains is to sand the surface and remove minor irregularities on the surface. The procedure for repairing floors will depend on the number of existing floor screed defects, the conditions for their elimination.
There are metal staples specifically designed to repair long cracks. But even here the installation process does not take much time and money. The technology must be followed everywhere to obtain a positive result. All these subtleties will allow you to get an answer on how to level the floor in a new building.
Elimination of irregularities
The floor in a new building will not always match the level. Irregularities are not excluded even with self-filling, not to mention industrial.
The view of the entire room immediately deteriorates, since the main attention when entering the room falls on the floor. In this case, you can level the floor using a milling machine.
If unevenness in the concrete floor is found, the sequence of repairing the floors should be determined. First of all, a deepening is made in the place of unevenness. 10 mm will be sufficient not from the surface of the site, but the measured level of the floor. These concepts differ from each other and have features. A primer is also used here to increase the adhesion of the mortar to the base, which covers the entire repaired area. In this case, it is necessary to dilute the primer mixtures with a solvent or solvent. The proportions should be observed in a ratio of 1 to 10.
As soon as everything is completely dry, you can begin to prepare the solution and pour it over the entire surface. The leveling of the mixture is carried out using a rule or rail. Once dry, the concrete floor can be sanded.
Large amount of dust
Due to poor-quality performance of work on the device of the floor screed, you may encounter an increased level of dust in the room. It all comes from the base and goes up. Breathing and generally being in the room becomes problematic. Even wet cleaning will not allow you to cope with such a problem. You will need high-quality apartment renovation, walls and screed.
The best option in this case is to use special paints or compositions. These can be various impregnations from leading manufacturers.
For repairs, you just need to apply them in several layers to the surface of the concrete floor and leave to dry completely. Compounds can easily penetrate into the screed to a depth of 5-6 mm, creating a protective dome. This allows you to reduce the appearance of dust in the future to a minimum threshold.
Using such compositions for work, the floor surface becomes more attractive in appearance. Some of them have additional qualities, the ability to withstand high and low ambient temperatures, and withstand wear.
Such a foundation can serve for a long time. But here it is worth paying attention to the specific premises where such methods can be applied. Often it is a bathroom and a toilet. But if a protective primer is used, then the scope is somewhat expanded.
All types of floor repair in an apartment have their own subtleties. Each of them requires attention and strict adherence to technology, sequence of work. This method is popular due to the simplicity of the work, as well as the low final cost. True, in the latter case, everything will depend on the purchased material.
Not everyone knows about the floor screed, at what stage of the repair should be performed. Of course, it is best to provide for all types of dirty work at this stage, and only after that start pouring. But in any case, the technology must be fully followed to avoid problems with the quality and strength of the surface. Serious mistakes can be made when leveling the sub-floor in a new building.
- The compositions and mixtures that are necessary for a specific type of repair are not always purchased. There are no universal materials that can provide excellent results. Even one manufacturer has a huge assortment of materials, depending on the type of screed, conditions of implementation, premises and other points.
- Poor adhesion of the solution to the base occurs due to the presence of grease stains, paint or putty stains. In the future, this can lead to cracks and destruction of the floor covering. The preparation of the base should be given maximum time and attention.
To improve the quality of adhesion, the surface should be primed. But many people forget about it. The result is a flaking floor with a lot of cracks. Even finishing will not help. If the base is also loose, then it is better to process it in two or even three layers.
- Doing your own floor screed is good. But not everyone knows how to level the floor in a new building efficiently. A single execution will lead to premature drying of the prepared solution. So it's best to get an assistant. It is the time frame that is key when using self-leveling compounds.
- The stage of choosing the floor covering is very important. At the same time, attention is drawn to the level of the floor screed in the new building. If there will be tiles in one room, and laminate in the second, then the fill level should be slightly different, depending on the thickness of the material used. In this case, you cannot perform the screed at the same level throughout the room. It is very important here to take into account the thickness of the "warm floor".
- Wait for a technological break before laying the topcoat. These terms are allotted by the manufacturer himself and are indicated in the instructions for the mixture. If the time frame is limited, then the compositions should be purchased appropriate - with a quick set of strength.
- We must not forget about the protection of the screed after pouring from drafts and direct sunlight. Without this, the solution will dry out unevenly, and defects will immediately begin to reappear.
When leveling the floor and repairing individual areas, the technology should be strictly observed. Only in this case will the final result please everyone.
