Some people cannot imagine that there can be no cracks on the screed, and they believe that it is impossible to do without them. Of course, in many cases, the presence of cracks will not affect the quality of the floor. But this is only when sheet material is located on the concrete floor, or a thick layer of linoleum. But if the screed has a mobile state, then the presence of cracks is not very good.
Despite the fact that many use exclusively mortar screeds, however, the mixtures with the filler have a little more advantages. First of all, mortar screeds are best used for the capital sex, however, for repair work, it is also suitable. If the floor screed consists exclusively of concrete, then the flooring can be obtained without a single crack. But if you use high -quality filler, then the quality of work is significantly increased.
Materials such as expanded clay, gravel, aerated concrete, and other materials can serve as a filler. At the same time, one tenth is the share of concrete. For a dwelling, it is best to use a light type of concrete, and for a industrial premises – a heavy type of concrete. With the help of these screeds, the floor can be made very durable, and it is also unlikely that there are cracks.
The first layer of the screed is created from concrete, and then it is covered with a thin layer of solution in order to hide all the pebbles or fossa. Mortar screeds are used when the crack has up to 4 cm. If there are more cracks, then it is better to use concrete. It should be noted that the coating with a screed will increase the life of the flooring, and will also look attractive.
