2021-3-14 · An ordinary cement-bonded screed requires additional reinforcement with reinforcement meshes or the Staenis grid. Alternatively, you can opt for a fibre-reinforced screed (fibre compound) or anhydrite screed. In this case, you go for a minimum thickness of 50 mm for cement-bound screed. The minimum thickness for anhydrite screed is 40 mm.
2018-7-12 · I was planning to use synthaprufe, blinded with sharp sand and then lay a cement sand screed over. However, the thickness of the screed at a minimum would only be 30mm (it increases to about 50mm across the width). I have read that 50mm is the minimum for unbonded screeds (and Synthaprufe data sheet says it should be a min 50mm).
