Screed movement joints and the finish above them

BULDX product guides5 October 20262 min read

Coordinate a screed joint with the floor finish and the joint layout below. A finishing layer should not accidentally bridge a movement line that the design intends to preserve.

AI-generated application context: Screed movement joints and the finish above them — APPLICATION ILLUSTRATIONAI-generated application illustration for this guide. Not a completed BULDX project or an installation drawing.

Selection considerations

Show screed depth, floor covering and adhesive layers on the same detail. Establish whether the joint is for crack control or movement accommodation. Different functions may require different treatment through the finish.

Check profile height against the actual screed thickness and plan transitions at doors or material changes. Keep the selected joint free of rigid finishing material where movement is required. Label the finish contractor's responsibilities in the method statement so the intended detail survives the handover between trades.

Before you specify or order

Draw screed and finish together
Distinguish movement from crack control

Common question

Can a screed joint be hidden under continuous tile?
