flow screeding

Flow Screeding Description:

Anhydrite liquid flow screeding is a blend of special additives and selected aggregates mixed with clean potable water to produce a pumpable self smoothing, flowing screed (manufactured to BSEN 13813:2002).


Anhydrite liquid screed is designed to provide a smooth level surface in both commercial and domestic buildings prior to the application of floor finishes. It can be used Bonded. unbonded or floating and with or without UFH.


  • Self compacting
  • Self curing.
  • Can be walked on in 24-48 hours.
  • Can be loaded after 7 days
  • No reinforcement required.
  • Ideal for use with under floor heating
  • Can be force dried as early as 7 days after application.
  • Dries at a rate of 1mm per day up to a screed depth of 40mm in good drying conditions
  • Easily achieves SR2 finish as described in BS8204.
  • Protein free – cannot harbour harmful bacteria.
  • Non combustible (tested to BS476 Part 4).
  • Minimal Thermal expansion (0.012mm/mK).
  • Excellent thermal conductivity.
  • Environmentally friendly

With any new project or renovation, it is important to get a flawlessly flat and solid support in order to lay your desired floor.

Thanks to its high fluidity, self-compacting flow Screeding solutions allow you to get an exceptional flatness on any type of support whether it is concrete slabbing or wooden flooring.

This high level of performance allows you to directly lay tiles to very large sizes over 60 x 60 cm. Flow screeding due to its high level of productivity, ease and efficient application, will generate a significantly even finished surface, with professional result.

Through the removal of any unattractive seams in doorways and the middle of larger rooms it creates a more beautiful floor.
