Frequently asked questions
What thickness for a screed?
About 3 to 5 cm for a bonded screed and 5 to 7 cm for a floating screed on insulation. Follow the requirements of your floor covering.
What cement dosage?
Traditional cement screeds are often mixed at 300 to 350 kg of cement per m³. Ready-mixed products have their own data sheets.
Does the calculator handle levelling compounds?
For self-levelling compounds sold in bags, use the manufacturer’s consumption per m² and mm instead.
