Everyone knows that the screed is the upper often upper floor overlap. The quality of the floor covering on top depends on how it is done correctly. All the materials that are used today – laminate, linoleum, parquet – need screed. This is especially true for old buildings. At the time when they were erected, there were no certain requirements for the floors.
Before you put the screed, especially if you do it yourself, you need to conduct a small calculation. If you will do its workers, then stock up on the apparatus from the ASK-Rentgen, with which you can check the thickness of the screed.
This type of coating on the floor is necessary for obtaining the maximum flat surface, ensuring the dynamic and static strength of the future structure, uniform distribution of load on the lower layers and creating the desired slopes on the floor.
Therefore, the following requirements are presented to the screed: mandatory strength and withstanding the load on compression up to 15 MPa, homogeneous thickness over the entire surface, the absence of cracks of cracks and irregularities.
To obtain screed on the floor, a cement-sand mortar and concrete are used. In addition, in stores today you can find dry and leveling mixtures, the choice of which depends on the type of future flooring.
A concrete or cement-sand screed is selected for the parquet. But most often today they use ready -made dry mixes that are easier to prepare, use, and they need a small amount of water.
