How can joints and cracks in the substrate be reworked according to rules and standards?

With UZIN RR 203 and UZIN MK 92 S.

Cracks and artificial joints must be closed prior to the installation of wood flooring. 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 wood flooring, they mustbe closed. The proven system UZIN MK 92 S, combined with the crack bridge UZIN RR 203, is suitable for both cases.
