Several recent publications have dealt with plastering materials, backgrounds and techniques. The Station still receives many enquiries about defects and failure in new work. This Digest therefore approaches the subject from a different angle: the underlying causes of failure, and the principles governing the design of plasterwork to avoid or to overcome them. A table sets out the various types of background, their liability to moisture movement and other characteristics affecting plastering, with the types of plasterwork likely to prove satisfactory.

Includes corrections for Digests 55 and 67.
