How is the floor screed properly handled?
Unfortunately, the quality of screeds made inapartments is very low, which leads to the need to perform such work independently, and therefore the question of how to properly make the screed, is quite relevant. Often the cause are differences in floor height, hillocks, pits on the floor surface, etc. The only way to solve such problems is to level the floor with a screed, which is very simple by the procedure of execution and can be done independently.
Characteristic features of the screed.
Determining how to make a floor screed you need to understand what kind of screed is involved, because each species from the whole variety requires separate knowledge and skills and differs in its characteristics.
Cement and concrete screeds are characterized by theirsusceptibility to subsidence during drying, peeling off the substrate, severe cracking, coiling, etc. In connection with these indicators they are used only if it is necessary to perform a screed thickness of 5 cm, since such construction materials are relatively inexpensive and can significantly reduce the cost of screeding floors. Answering the question - how correctly to make a screed independently on beacons - it is necessary to recommend kneading as thick a solution as possible and add to it a clay aggregate of about ½ of the total volume of the screed mix.
When tightening and leveling, usinggypsum mixes and expanded clay, you can get warm floors and light floors that are minimally susceptible to subsidence, cracking, etc., while this kind of screed guarantees a good noise insulation. It should be taken into account that the gypsum screed will cost more than cement or concrete, almost 30%.
Methods of screed.
Currently, there are a number of waysand receptions by means of which the floor screed is carried out by oneself. Let us dwell in more detail on how to properly make a screed, i.e. optimally correct and fast.
When using the installation andaligning beacons, followed by a floor screed with their own hands, you need to screw in the floor screws with a flat hat and align them with the rule and level, i.e. set beacons. The rule, lubricated with oil, should be put on screwed screws. The empty space formed as a result must be filled with a mixture prepared on the basis of alabaster and sand concrete. After the beacons dry, a plaster or concrete screed is stretched by the rule, while removing excess solution. But this method has a significant drawback, namely, the fragility of lighthouses. If it is necessary to regularly level the screed surface, the beacons will be wiped, so the number of passes is limited. But just such a floor screed with your own hands is the most simple, and therefore it is used quite often.
The second option, in fact, is similar to the first anddiffers only in that it is necessary to install metal beacons on a screwdriver to be screwed, which are not wiped by repeated passes through them, while the floor screed is being made by hand. But without sufficient experience to establish, and also to level such poppies is very difficult. It is because of this that the first option - how to make a floor screed - is most suitable for leveling with a plaster or cement wet screed without sufficient experience, and the second option is optimal for professionals who are familiar firsthand with how beacons are set up and the cement, concrete or gypsum floor screed with their own hands.
Remove installed beacons from the producedScreeds can be after it completely "grab" and be able to withstand your weight. After removing the beacons of emptiness, pour the same solution that was used to perform the screed. This will make the screed monolithic. Pour emptiness immediately after loosening the beacons, otherwise the solution will dry out unevenly, which can lead to longitudinal cracks along the edges of the screed.
All that was said about now is just general rules and recommendations, but if you follow them, you can get a flat surface on which you can lay any cover.
