Floor Preparation

Liquid Screed should only be laid on a suitably well prepared substrate. The screed can either be laid bonded or over a separating polythene layer (usually a 500 gauge.) The separation layer can be either thermal or acoustic insulation. Edge strips are recommended around the perimeters, hard standing or pipes and joints placed where appropriate. Screed height is established by laser level from a datum and tripods across the floor.

Preparation is the key to a successful installation, Easyflow can supply and fit the materials required to prepare your floor for a liquid screed.


Thermal and acoustic insulations supplied and fitted if required.


It is necessary to create a barrier between the foil backing on the insulation and the screed.

It also tanks the room as the screed is so fluid.

Without the polythene, a reaction may occur affecting the structural integrity of the screed.

Perimeter Expansion Foam

Is necessary as there is some contraction and expansion within the screed usually within the first 24 to 48 hours of curing.
