Cemfloor liquid screed is a high-performance cement based, free flowing, self-compacting liquid screed developed by McGraths in Ireland. It can be installed very quickly (up to 2000m2 per day) saving time, foot trafficked in 24-48 hours and dries within 10-28 days with minimal shrinkage (<0.05%). It is suitable for a variety of applications; commercial and domestic floors, under-floor heating, wet rooms, un-bonded or floating floors, new builds or renovations and single or multi story projects. Cemfloor liquid screed is only installed by fully approved and trained applicators ensuring quality is never compromised.

Its fast-drying properties ensure floor coverings such as tiles can be applied at a final moisture content of 5% and hard wood/timber floors can be installed at a final moisture content of 2.8%. This significantly speeds up the entire build process compared with calcium sulphate screeds, which require a final moisture content of 0.5%.

Cemfloor liquid screed boasts exceptional thermal conductivity of up to 2.9W/mk and is very suitable and responsive to under-floor heating due to the fact it can be laid in very thin sections. This ensures lower energy bills and running costs.

  • Ideal for domestic and commercial screed requirements / applications.
  • Compatible with all floor coverings.
  • No need for surface grinding prior to application of floor coverings
  • Up to C30 strengths and F6 flexural ratings available.
  • Cemfloor liquid screed dries within 10 – 28 days (subject to chosen floor coverings)
  • Ideal for wet under floor heating systems.
  • Fast installation
