Definition
Self-levelling screed is a fluid cement or gypsum mortar poured on the floor after a primer, spreading and levelling under its own weight, usually 3 to 10 mm thick depending on the product, to prepare the surface for vinyl, SPC, parquet or epoxy.
Why it matters on a project
Thin floor finishes show every defect beneath them. Good levelling prevents waviness and opening joints.
Measurement and pricing
In square metres, stating thickness.
Common mistake
Pouring it on a dusty floor or without primer, so it cracks or debonds.
Frequently asked questions
Does it replace a cement screed?
No, the screed corrects levels; self-levelling gives a smooth surface on top.
When can flooring go on it?
After it dries to the moisture level the flooring manufacturer sets.
