The appearance, evenness and life of the laid flooring depends on the quality of the screed. Even organized by all construction standards and rules, the screed “obsolete”, losing its qualitative properties.
You should start the repair with the subsequent replacement of the floors by examining the screed for the presence of chips, cracks and recesses. This stage is not recommended to neglect. Otherwise, all these defects will appear on a new flooring in the form of tubercles and dents.
If, during a visual inspection, damaged areas are less than thirty percent of the total screed, it can be repaired. This will significantly save time and cash costs.
The procedure for the work performed:
1. After removing the flooring, the level of screed is determined by the rule. The protruding tubercles and mounds are knocked down by a perforator.
2. Cracks available in the floor slabs are covered with mounting foam.
3. The cement mortar is kneaded.
4. The depressions formed after knocking down and the fossa screeds already available on the surface, molested cracks and chips are filled with solution, and are aligned with the construction rule. After that, it is necessary to let the solution dry completely, and process the entire base of the screed with a penetrating primer.
5. The finished mixture or a bulk floor is poured on the primed base. Apply the finish layer in small areas, since the mixture quickly dries. Each section after filling is aligned with the rule and processed with a grater before drying out. At the end of the work, the surface is once again primed.
If you arrange production, then you will need ventilation. Aries — the most productive valve of supply ventilation, is of high quality. This valve will quickly and effectively cope with ventilation in any room. Its throughput is high.
