Semi-dry and flowing self-levelling screeds mixes are based on fine graded aggregates, hydraulic binders (cement or anhydrite), water and additives. Both have in common the fact that they are used to obtain a defined level and a solid smooth surface suitable to receive the final flooring and that they are supported by a load-bearing structure such as a slab.
The differences between semi-dry and self-levelling flowing sub floor screed mainly concern the consistency and the method of application. It is important to be familiar with them in order to choose the most suitable screed according to the needs of the construction site.
