gräfix 46
Calcium sulphate self-levelling screed
CAF C25 - F4 · self-levelling, pumpable screed, ideal for use with underfloor heating
The ideal sub-screed for all floor coverings inside buildings. It can be applied very effectively in conjunction with underfloor heating, on insulation layers, separating layers and as a bonded screed. The difference between the two products lies in the higher strength class. The flexural tensile strength and compressive strength are higher in gräfix 47.
Coverage: 30 kg with approx. 4.5 l water = approx. 15.9 l self-levelling screed
1 metric tonne with approx. 160 litres of water = approx. 530 litres of self-levelling screed

Calcium sulphate self-levelling screed
Pour, spread, smooth – done!
gräfix calcium sulphate self-levelling screeds (anhydrite self-levelling screeds) are ideal for indoor use with all types of floor coverings (subject to restrictions in wet rooms). They are very easy to work with and can be installed in conjunction with underfloor heating as a heated screed, as a floating screed on insulation, as a screed on a separating layer or as a bonded screed.
Water is only added on site. The major advantages over self-levelling screeds supplied in wet form are the flexible delivery logistics and the ability to reuse any unused dry mortar; this helps to avoid waste. The production, monitoring and delivery of the self-levelling screeds are subject to strict controls. These are self-levelling, pumpable screeds that are supplied as factory-mixed dry mortar.
