Midlands Floor Screeding have been involved with the installation of calcium sulphate screeds since they entered the UK market 25 years ago. The most common flowing screed is calcium sulphate, using either the Gyvlon or Gypsum binder for which both arefully BBA Approved- ensuring quality and performance.
The important characteristics of a flowing screed are as below:
Speed up build programme
Screed deadlines are critical, flowing screed can be installed at up to 200 m² per hour. After pouring, flowing screed products can receive foot traffic from 24 to 48 hours.
Drying time for a screed is approximately 1mm per day, up to 40mm. Beyond 40mm, 0.5mm per day. Underfloor heating, may also be used to reduce the screed drying time. After 48 hours, the building must be properly ventilated.
Flexibility of floor coverings
Flowing screed requires fewer expansion joints than cementitious screeds. Reducing expansion joints preserves the look of the floor finish.
Improving the efficiency of underfloor heating
As a free flowing and self-compacting screed, flowing screed is versatile for most build types and is compatible with most acoustic and thermal insulations.
Cementitious Flowing Screed
In recent years, cementitious flowing screed have entered the UK market, providing a fast-drying option in comparison to calcium sulphate screeds. The options are Tarmac Belitex or Cemfloor.
