Green screeds are usually 1:3 or 1:4 cement and sand at a usual thickness of 50mm. These screeds can be applied both bonded directly onto a concrete base or un-bonded (applied on to a polythene sheet damp proof membrane). Both screed and concrete are referred to as being green during the period from application through to the time it gains strength and reaches dimensional stability.
Flexible adhesives and grouts, which tolerate movement, compensate for the shrinkage in the substrate and yet still allow the screed to evaporate excess water through the grout joints. They are ideal for fixing ceramic and porcelain tiles as well as calibrated stone and slate.
Screeds should be firm enough to walk on, usually at least 3 days after application, before tiling can be started.
Concrete should be at least 7 days old.
All substrates to be tiled must be clean and surface dry.
Particular care should be taken that movement joints are adequately specified.
Fix the tiles into a solid bed of weberset pro lite - rapid at 5 mm thick.
Leave joints at least 3mm wide for grouting and make provision for movement.
Grout the joints with weberjoint wide flex and use weberjoint silicone to fill perimeter movement joints.
