gräfix 42 S
Quick-set screed
CT C25 - F4 · Rapid-setting screed for creating a bonded cementitious screed, over a separating layer or over insulation layers
gräfix 42S, a cement-based screed containing crushed limestone sand and additives that improve workability and accelerate setting, is ideal for all floor coverings in residential construction, provided that normal levels of wear and tear are expected. The cement screed is laid as a bonded screed on a separating layer or as a floating screed on rigid foam boards or other insulation boards, and can be walked on after just a few hours. The installation thickness complies with DIN 18560.
