Before those who do or are going to start repair, sooner or later the question will arise how to make the floor perfectly even. For those who use bulk floors, they will not be a problem to align them. If you do not have a very flat floor or large enough differences, then you are faced with the task of making a screed of the floor.
The floor screed is a thick -sided mix made of cement, sand and water, which is applied to a concrete base in order to align it for subsequent finishing work. The main task when performing the screed is to create an absolutely smooth and strictly horizontal reliable surface in order to then lay finish building materials, for example, tiles, linoleum or parquet. At the same time, do not forget that the screed itself should not be used for a long time open.
One of the types of screeds used at the moment is the dry floor screed, for the implementation of which new material invented by German scientists is used. It is a plate of gypsum containing a substance that has a waterproofing coating.
The dry screed has the following advantages: drying is not required and a fairly small weight is.
The screed is laid only on the prepared surface. T. To. It is impossible to achieve complete concrete purification, the base is treated with a primer for better adhesion to the screed.
When using the method of dry screed, the presence of at least two people is necessary, one of whom will interfere with the solution, and the second to make the screed itself, t. To. The process should be continuous. First, the solution is kneaded, then it is dumped against the wall opposite the entrance, because about half a meter should be pulled right away. The solution with a trowel is aligned and begin to pull it on, so the process is called the “floor screed”. It should be performed quickly, without stopping, so while one person makes the first part of the screed, the second prepares the solution for the next batch.
