What Is Liquid Screed?
Liquid screed, also called flow screed, is a self-levelling floor screed that’s pumped into place rather than laid by hand. It flows out across the floor, finds its own level and sets to a smooth, flat surface ready for your final flooring.
There are two main types. Anhydrite screed uses a calcium sulphate binder, lays very flat and conducts heat well, which makes it the go-to choice over underfloor heating. Cement-based liquid screed behaves the same way but can go in wet areas and be force-dried sooner. We’ll tell you which one suits your floor.
Because it’s pumped, a liquid screed floor can be laid much faster than traditional screed, up to 500m² in a single day, with far less labour on site.
Benefits of Liquid Screed
Fast to Lay
Pumped straight into place, so large areas are finished in a single day.
Flat, Level Finish
Self-levelling means a consistently flat surface with minimal preparation before flooring.
Thinner Floors
Can be laid thinner than traditional screed, keeping floor heights down and loads lighter.
Perfect for Underfloor Heating
Flows fully around the pipes with no air pockets, so heat spreads quickly and evenly.
Less Cracking
Low shrinkage means fewer cracks and curling than sand and cement.
Walk On Quickly
Light foot traffic is usually possible after 48 hours.

How Much Does Liquid Screed Cost?
Liquid screed costs around £30 per m² supplied and installed, based on a floor of about 150m² at 75mm. The final price depends on depth, floor area and access for the pump. Larger areas cost less per m² because the pump and crew set-up is spread across more floor.

Liquid Screed FAQs
What is liquid screed?
A self-levelling floor screed pumped into place. It sets to a flat, smooth finish and is ideal over underfloor heating.
Is liquid screed better than traditional screed?
For large floors and underfloor heating, usually yes: it’s faster, flatter and can be laid thinner. Traditional screed is better where you need falls, a bonded finish or a very hard-wearing surface.
How thick can liquid screed be laid?
We usually lay liquid screed at 50–70mm, with 15–20mm of cover over underfloor heating pipes. Deeper pours are possible but take longer to dry.
How long before I can walk on liquid screed?
Light foot traffic is usually fine after 48 hours. Heavier loads and flooring need to wait until it’s properly dry.
How much does liquid screed cost?
Around £30 per m² supplied and laid, with a minimum charge of £650. Send us your floor area for a fixed quote.
