Screed Calculator
How do I estimate the volume of screed I need?
Multiply the floor area in square metres by the screed depth in metres to get cubic metres (m³). Add 5–10% wastage. The calculator below does this for you — enter the dimensions in metres and the depth in millimetres and it returns the volume of liquid flow screed required — whether Anhydrite, Cemfloor or Latex.
80mm max
Recommended minimum depths
| Bonded | ~25mm |
| Unbonded | ~30mm |
| Floating | 35–40mm |
| With underfloor heating | 40–50mm |
Enter your length and width above to calculate your screed volume estimate.
Why choose liquid flow screed?
Liquid flow screed is the industry standard for new floors. Self-levelling, self-compacting, walkable in 24–48 hours, low shrinkage, ideal for underfloor heating, and dramatically faster to install than traditional sand-cement. Available across London, Surrey, Essex and the South East.
What happens after I get a quote?
We confirm the specification (screed type, depth, area), agree a pour date that fits your build programme, and arrive on site with the mix ready to pump. Typical install time for a standard residential floor is half a day. Light foot traffic returns within 24–48 hours — see our drying times guide for full curing schedules, or request a quote to get started.
