General information
Ease of use of modern self-leveling mixturesis the most important advantage. Even a layman, having carefully read the instructions, being careful, with some effort, can qualitatively prepare the base for the finish coating using the self-leveling floor.
Using modern self-leveling mixtures, you don’t have to install beacons, as nature will do everything for us.
Small carpets (flaws) of the concrete base, the liquid solution will completely fill, level the relief, level the lowlands with hills. Of course, the reason for the base is discord, and if the difference between the peaks and troughs is large, it is clear that one layer of filling is unlikely to be enough.
In such cases, it is very important to correctly select the mixture, in other words, it is necessary to use the mixture in accordance with its ability. In order not to make a mistake, carefully read the instructions on the packaging, consult with sellers.
Self-leveling mortars of bulk floors set much faster than conventional cement-sand screeds. This ability is one of the advantages of bulk floors, as it greatly speeds up repairs.
From the thickness of the fill and the composition of the mixture itself, the time directly depends on the time of completion of work with a leveling solution to the laying of the decorative coating.
Typically accepted: every 3 mm. hold the layer for 24 hours, respectively 6 mm. - 48 hours.
Quick-setting cement poured floors allow laying in 3-6 hours.
Of course, if it is possible to buy an apartment in Moscow, the above knowledge may not be useful. Experienced real estate agents will choose any option for you, in any district of Moscow and the Moscow region. But, if finances sing romances - read the instructions for making self-leveling floors in detail
Choose a leveling (bulk) composition
When choosing a leveling composition, look at the root, pay attention to the manufacturer's recommendations and follow all his wishes.
A bona fide manufacturer must indicate on the packaging the maximum layer thickness and the pot life of the sealed mixture (this is the period in which all operations with it must be completed).
The package must indicate the time required to gain strength necessary for moving around the floor, laying tiles, laminate, parquet, etc. and this is also an important point and often for different materials, different periods are needed.
What is required for work
You will need:
- leveling mixture of proper quality;
-universal primer, it is necessary for moisture-absorbing substrates, it can be designated as a deep penetration primer;
-electronic moisture meter;
-building level;
- capacity for dilution of the solution;
Drill with nozzle for mixing the solution;
- roller for primer;
-racles for leveling the solution;
- needle roller to remove air bubbles;
-putty knife
Progress - step by step instructions
Step one.
In order to choose the appropriate primer, it is necessary to determine the type of substrate. There are certain methods, namely: pour some water on the base.
If the spilled moisture quickly leaves, this suggests that a special primer is needed for absorbent substrates. If you are at a loss in choosing the type of substrate, purchase a universal film-forming primer.
Step Two
Constantly monitor the moisture content of the substrate. Use a moisture meter for this. According to the carbide method, the humidity must be, for the application of leveling mixtures, not higher than 2% SM. If humidity is higher - ventilation is required.
Step Three
Using the level, check the evenness of the base. Large cavities and cracks are filled with a repair mass using a spatula.
After the repair mass is set, namely after 30-60 minutes, we carry out further work.
Step Four
For better adhesion (adhesion) of the self-leveling mixture to the base, we treat the base with a primer. It is good to use a primer and a self-leveling mixture of the same company. After 20-30 minutes we continue to work.
Step Five
We close the dry mixture, purchased taking into account the above recommendations, with water in the proportion indicated on the package. Using a drill with a mixer nozzle, mix the solution. An important point: be sure to pour the dry mixture into water, and not vice versa, otherwise lumps will remain, which is unacceptable.
Step Six
Within 20-30 minutes, not later, evenly pour on the surface of the base, a liquid self-leveling mass.
Seventh step.
Do not seek to immediately fill the entire area, use dividers. Gently pouring the solution from the container, using a squeegee, distribute it to the desired layer thickness.
Step Eight.
Immediately, after pouring the solution, using a needle roller, we remove air bubbles, otherwise, after drying, lunar craters will remain. Then knead the next portion of the solution and repeat steps 6-8. And so on until the entire floor is covered. The next layer can be applied only when there are no dark wet spots on the previous one.
