The repair of the floor screed should begin with the detection of defects on the basis that it is planned to be repaired. To prevent the passage of exfolved sections of the floor, it is necessary to tap its entire area, if when you hit the surface you hear a dull sound, this indicates the detachment of the screed section. Such areas must be cut out. After finding all the exfolved areas, they must be covered with a special mixture. In the case of the destruction of the old screed with a volume of more than 30%, its full replacement will be the best solution.
