What it is
For thin screeds, a sand-cement mix is used; thicker screeds use fine concrete with small aggregate. Polymer and fibre additives reduce cracking.
Key points
- Sand-cement for thin layers
- Fine concrete for thicker layers
- Fibres reduce shrinkage cracks
- Cured like any concrete
Why it matters
A screed that is too wet or not cured cracks and dusts, and the tiles above sound hollow.
How Elamentt handles it
Screeds are mixed to the specification and cured before finishes go on.
