Fibre-modified, quick drying floor screed mix

25kg bag.

weberfloor flex is a self-smoothing floor levelling compound — often incorrectly referred to as a self levelling screed or self levelling floor compound — which can be tiled onto and is an easy screed for applying onto floor substrates subject to some movement, such as wood or underfloor heating. 

Flowable liquid floor screed suitable for applying up to a depth of 5-50mm onto:

  • Floors with underfloor heating or under tile warming
  • Cement
  • Concrete slabs
  • Pre-cast elements
  • Wooden flooring
  • Existing ceramic tiles
  • Existing rigid plastic tiles
  • Floating floors (e.g. insulation board)
  • Bitumen residue*
    * Best practice is to remove all bitumen prior to application

Features and benefits

  • Extra flexible levelling screed for substrates subject to movement or expansion
  • A high performance alternative to a latex self levelling compound
  • Low Dust Technology™ reducing the amount of dust expelled during the mixing process
  • Suitable for use as a under tile warming and underfloor heating screed
  • Quick drying screed — can take light foot traffic or be tiled onto after 1-2hrs
