Guide to Portland Cement-Based Plaster
2004, 28pp
$63.50

This guide provides information on the plastering process. The facets of plastering covered are the prequalification of materials, plaster tool and equipment requirements, plaster mixture proportions, plaster application procedures, types of finishes, and troubleshooting and repair. Portland cement-based plastering differs in many ways from that of the concrete trade. Differences in terminology are of key importance; therefor, a familiarization of plastering terminology is needed. A glossary of plastering terms is provided for this reason. This guide is intended for use by architects, engineers, designers, specification writers, contractors, plasterers, laboratory personnel, and public authorities for familiarization with the plastering process and as an aid in specification writing.

Keywords: admixture; base; bond; brown coat; cement; cracking; curing; finish coat; furring; hydration; masonry; plaster; proportion; reinforcement; scratch coat; shrinkage; stucco; texture.
