Proprietary screeds are specified on some of the separating floors. What is meant by a Proprietary Screed?
A proprietary screed is a self-compacting floor screed, which achieves a nominal mass per unit area of 80 kg/m2 as laid, without the requirement for manual or mechanical compacting. Where a robust details floor specifies the use of proprietary screeds in conjunction with an underscreed resilient layer, the proprietary screed should be installed on a polythene membrane to prevent ingress of the screed to the resilient layer. Membranes or other materials must not be provided beneath the screed where the robust detail states that the screed should be ‘directly applied’ to the structural core floor.
