How can cracks and joints be permanently repaired?

With UZIN KR 516.

Cracks and joints must be repaired prior to floor covering work. Whilst artificial joints are deliberately made in the surface, cracks represent damage which may have different causes. In both cases, the edges of the screed plates must be bonded together again to avoid subsequent telegraphing in the surface of the floor covering. Only 2-component products, capable of building high cured strengths in a short time, are suitable for the connection of the screed edges. The 2-component silicate resin UIN KR 516 stands out in particular by its early strength which is reached extremely rapidly. The curing time can be controlled by the amount of hardener added.
