Application

  • Sub-floor levelling.
  • Unbonded, bonded and floating floor constructions.
  • Suitable for both residential and commercial floors.
  • Suitable for use with under-floor heating systems.

Description

A Portland cement based, pump applied, liquid floor screed.

It has been designed to comply with BS EN 13813, screed material and floor screeds - screed material - properties and requirements.

The flowing characteristics means that it is self-compacting, thus voids and poor compaction are virtually eliminated.

As with virtually all screeds, it is not a wearing surface and it therefore requires a suitable floor covering. Can be used with all standard floor coverings i.e. tiles, wood, carpet, vinyl.

Features and benefits:

  • Increased productivity – 1000 m² per day can be easily achieved.
  • Significantly reduced thickness when compared to traditional sand: cement screeds.
  • Reduced depth means reduced weight and drying times.
  • Increased efficiency of under-floor heating system.
  • Faster heat response time with under-floor heating.
