Screeds that are produced in conjunction with a load-bearing substrate may either be used as they are or may be given a top covering. The thickness of the composite screeds here is not the deciding factor for its load-bearing capacity, as it is the combination with the load-bearing substrate which already guarantees that all static and dynamic forces are being absorbed.
Putting in place special bonding courses takes care of the screed, producing a secure bonding with the substrate. Any potentially present residues of concrete admixtures and after-treatment agents must not impair adhesion. Cracks in the load-bearing substrates may also cause cracks to form in the composite screed.
They should therefore be closed and made good completely, prior to installing the screed.
With a fast over coating time of just 4 hours and the low-shrinkage curing behaviour even extremely tight construction times no longer pose a problem.
The low-shrinkage setting enables a damage-free installation of the coverings made of tiles and natural stone.
