How can joints and cracks in the substrate be repaired?

With UZIN RR 203 and UZIN MK 92 S.

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 must be closed. The proven system UZIN MK 92 S, combined with the crack bridge UZIN RR 203, is suitable for both cases.
