POLYS PRÊT® 800 Screed is a light, ready-to-use screed, specially intended for lightening structures, in new and renovation work.
It is also a perfect complement to thermal and acoustic insulation, compatible with all floor coverings. Its formulation is lightened by polystyrene beads (diameter 2-3 mm) and supplemented by fibers, which gives it great lightness combined with high mechanical properties.
This formulation ensures perfect homogeneity in the solution. All in flexibility, it smooths easily and uniformly, without the need for rework.
Its fiber composition - which annihilates the tedious installation of an anti-cracking lattice - and its simplicity of implementation make it a particularly functional solution.
