Flotherm Liquid Screed :

Larsen Flotherm Binder is a specially formulated calcium sulphate binder for the production of self levelling (flowing) floor screeds.

A high quality flowing screed can be produced simply by mixing with a suitable sand and water at a ready mix plant. Flowing screeds have many obvious benefits over traditional sand and cement screed: quicker to lay; thinner screed depth; less labour intensive; much lower risk of shrinkage or cracking but the main benefits are seen when they are used with underfloor heating systems. Flowing anhydrite screeds fully encapsulate the heating pipes without voids and need only to cover the pipes by 25mm, resulting in a much more responsive heating system which in turn is more economical to run.

  • Apply up to 1000m2 per day
  • Low shrinkage
  • Reduced screed thickness
  • Maximizes underfloor heating
  • Screed typically conforms to BS EN 13813 CA-C25-F5
