In London’s fast moving construction sector, flooring systems often need to balance speed, strength, and efficiency. Choosing the right screed can affect everything from project timelines to underfloor heating performance. Traditional sand and cement screed has been used for decades, but liquid screed has become a popular modern alternative. With over 15 years of experience, londonfloorscreeding.co.uk helps builders and homeowners across London select the most suitable option.
What’s the difference?
Liquid screed, commonly made from calcium sulphate or anhydrite, is supplied ready mixed and pumped directly onto the floor surface. The mixture spreads easily and naturally levels itself, producing a consistent finish without extensive manual work.
Traditional screed uses a semi dry blend of cement and sharp sand. It is installed manually, compacted, and smoothed with trowels. Because installers work the material by hand, they can create slopes or drainage falls when required for areas such as showers, wet rooms, or balconies.
Key comparisons
Installation speed
Liquid screed is pumped quickly across the floor, allowing large areas to be completed efficiently. Traditional screed takes longer because it must be mixed and levelled manually.
Thickness and load
Liquid screed can often be laid at around 35–40mm thickness, whereas traditional screed usually requires 50–65mm.
Drying times
Traditional screed dries slowly, typically around 1 day per millimetre thickness. Liquid screed can often be walked on within 24–48 hours and finished within a few weeks.
Underfloor heating performance
Because liquid screed surrounds pipes fully, it improves heat transfer and system efficiency.
Which should you choose?
Liquid screed is ideal for large open spaces, underfloor heating installations, and projects with tight schedules. Traditional screed remains useful where slopes or gradients are needed.
