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; therefore, a familiarization of plastering terminology is needed. Definitions of plastering terms are 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 processes and as an aid in specification writing.
