  • What is the difference between flowing screed and traditional screed?
    Flowing screed is a superior material for laying across large areas in a short time. Where sand and cement products can be problemtic in terms of curling and cracking after placement, flowing screeds have minimal shrinkage and no curling
  • What are the drying/setting times for floor screeds?
    Both anhydrite and fast drying screeds can receive foot traffic after 48 hours. Bonding a Floor Covering Anhydrite screeds - 1mm per day up to 40mm and 1mm every two days for anything over (a depth of 50mm would calculate - (1x40)+(2x10) = 60 days See force drying table using an underfloor heating system for anhydrite screeds only Force Drying Screed Table Fast Drying Screeds - Cemfloor and Integracure - 14 to 21 days
  • What are the floor tolerances on floor screeds?
    British Standard SR1 - High Tolerance - +/-3mm deviation under a 2 metre straight edge SR2 - Standard - +/-5mm deviation under a 2 metre straight edge SR3 - Utility - +/-10mm deviation under a 2 metre straight edge
  • What is the best type of screed for underfloor heating?
    Flowing Anyhdrite or cementitous.
  • What is the minimum depth of bonded screed?
    20mm
  • What is the minimum depth of un-bonded screed?
    40mm flowing.
  • Is there a quick drying floor screed?
    Cemfloor & Longfloor Integracure
