What is screeding? It’s a combined sand-and-cement-based material laid down to level a floor surface. Screed itself is a type of mortar and this is used as a base on which to lay down other flooring. It has a smoother appearance than concrete, despite it being made from the same constituents.
Screeding is mostly used on internal floors, with screed thicknesses typically measuring 50–100 mm (5–10 cm). An advantage is that screed can be used in homes with underfloor heating.
Screeding involves the levelling and flattening of the concrete surface: it results in a solid base on which the final or finishing flooring can be layered.
