RENOPLAN SYSTEM 4

How can cracks in the substrate be easily sealed? 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 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.

<p>
Widen the cracks to allow UZIN KR 516 to be easily poured into them. Treat cracks extending through the entire thickness of the screed by cutting cross-cuts down to 2/3 of the screed depth spaced approx. 25 cm apart; use an angle grinder for this purpose (e.g. Wolff screed groove cutter EF 135).
