Liquid screed is a modern alternative to traditional floor screeding methods. Often referred to as flowing screed, it is delivered to site ready mixed and pumped directly onto the floor. The mixture typically includes cement or calcium sulphate combined with sand, water, and additives that improve performance.
Once poured, the material spreads across the floor surface and levels itself naturally. This creates a flat and consistent subfloor without the need for extensive manual finishing. Many liquid screeds can be walked on within 24 to 48 hours, allowing construction work to progress quickly.
When should you choose liquid screed?
Liquid screed is particularly suitable for projects where speed and floor quality are important.
Underfloor heating installations
Because the screed flows around heating pipes completely, it removes air gaps and improves heat transfer, helping heating systems run efficiently.
Large floor areas
Pump applied screed can cover large spaces quickly, making it ideal for extensions, open plan homes, and commercial developments.
Reduced floor depth
Liquid screed can often be laid thinner than traditional screed, usually around 35–40mm. This helps reduce structural load and maintain floor height.
Fast project timelines
Quicker curing times mean floor coverings may be installed sooner compared with traditional systems.
High precision finish
The self levelling properties create a smooth and accurate surface, which is useful for tile installations and large format flooring.
Key benefits
Rapid installation
Using pumping equipment, installers can cover approximately 25m² in around 20 minutes.
Lower shrinkage levels
Compared with traditional screeds, liquid screed generally experiences less shrinkage, which reduces cracking.
Better heating performance
The screed fully surrounds heating pipes, improving thermal efficiency.
Competitive overall cost
Although the materials may be more expensive, faster installation can reduce labour costs, meaning the overall project price may be similar.
How it compares
Traditional sand and cement screed is still widely used and can be shaped to create slopes where required. However, it generally takes longer to dry.
Self levelling compounds are typically used in very thin layers to correct small surface imperfections rather than forming the main screed layer.
