Frequently Asked Questions
What is a cement floor screed?
A cement screed is a layer of cement-based material laid over a concrete subfloor to form a new level surface. It corrects height differences, builds thickness, and creates ramps or drainage falls. It shapes the floor before the covering or coating goes down.
When do I need a screed instead of a levelling compound?
Use a screed when the floor needs a new level, a build-up in height, or a shaped fall, typically from 15 mm up. Use a levelling compound when the floor is level but has shallow dips that need smoothing.
What does rapid-set mean for a screed?
Rapid-set screeds cure fast. Foot traffic is possible in two to four hours and tile-ready in about eight hours, so a floor can be laid the same day on program-critical jobs.
How thick can a screed be laid?
Bonded screeds start at a 10-to-15 mm minimum and can be built up in lifts. Unbonded and floating screeds start at 35-to-40 mm. Underfloor heating pipes must sit at least 25 mm below the surface.
Can screeds be used outside or under tiles?
Yes. Several screeds suit internal and external concrete, and most accept tiles, natural stone or terrazzo once cured. Some are not suited to timber or metal substrates, and none should be immersed in water or laid where rising damp is present.
