Traditionally, screed is laid around 75mm thick onto a concrete subfloor. It’s a skilled job, usually undertaken by plasterers when the walls and ceiling are plastered. A screed mix is relatively strong, using one part cement to three parts sharp sand, and when done well it gives a smooth and level floor on which to lay your chosen floor finish. A screed is also the preferred medium when laying underfloor heating pipes.
You do not have to use a screed. There’s nothing structural about screeds and some designs do away with one altogether. However, the floor beneath the screed is usually not laid to nearly such a high standard. Also, suspended precast concrete flooring systems, which are now increasingly being used instead of solid concrete slabs, have a noticeable camber which causes problems when it comes to laying most floor finishes.
