How can cracks in the substrate be sealed for easy concrete crack repair?

With UZIN KR 516.

Cracks and joints must be closed prior to floor covering work. Whilst artificial joints are deliberately made in the surface, cracks represent damages which may have different causes. In both cases, the cracks must be repaired to avoid subsequent markings in the surface of the floor covering.  UZIN KR 516 is ideal for concrete crack repair because it is capable of building high internal strengths in a short time. The 2-component silicate resin provides rapid, early strength and the curing time can be controlled by the amount of hardener added.
