ABSTRACT

Screed requires a high standard of workmanship to produce a durable finish. Excessive trowelling can produce surface crazing.

Large areas of screed laid in one operation can cause random cracking due to differential shrinkage. Alternatively, laying screeds in bays can cause the edges to curl. This may show through thin finishes. A rapid curing time for screed can result in considerable shrinkage and a general loss of strength of the screed.
