How can joints and cracks in the substrate be repaired?

With UZIN RR 203 and UZIN NC 182.

Cracks and artificial joints must be closed prior to the installation of the new floor covering. While artificial joints have been deliberately made in the surface, cracks represent damages which may have different causes. In order to avoid the joints and cracks showing through the floor, they mustbe closed. Combining UZIN NC 182 rapid repair and UZIN RR 203 crack bridge is a proven system and suitable for repairing both.
