Self-levelling screeds are very fluid mortars whose workability is such as to allow levelling with limited or no manual intervention.
These are screeds with a spread - measured with the Hagemann cone - of 22 cm: they spread homogeneously on their own, creating a smooth base with no unevenness.
They are mortars that have a high viscosity and a high fineness of the components to prevent the self-levelling screed from disintegrating.
