gräfix 47
Calcium sulphate self-levelling screed
CAF C35 - F6 · self-levelling, pumpable flowing screed, ideal for use with underfloor heating
The ideal screed for commercial or high-traffic areas. It can be applied very effectively in conjunction with underfloor heating, on insulation layers, separating layers and as a bonded screed. The flexural strength and compressive strength of gräfix 47 are higher than those of gräefix 46.
Yield: 1 tonne with approx. 155 litres of water = approx. 530 litres of self-levelling screed
Delivery: in bulk in a site silo (grain size 0–4.0 mm)
in bulk in the estro-mobil (grain size 0–4.0 mm)
- for areas subject to higher loads
- high installation output
- Curing with low shrinkage and low stress, without cupping
- High flexural tensile strength
- Optimal thermal conductivity
- Installation without expansion joints

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.
