Thrce-coat work is mandatory on all metal lath and edge supported gypsum lath on ceiling construction. Three-coat work is desirable on all gypsum lath. Two-coat work is acceptable on unperforated gypsum lath and masonry plaster bases. The UNITED STATES GYPSUM COMPANY maintains a qualified stalT of Technical Consultants, Architect Service Representatives, conveniently located in most major markets to assist in resolving specific problems. tJ BASECOAT PLASTERS DESCRIPTION The base of all gypsum plasters is gypsum rock, hydrous calcium sulfate, winch has a water content of about 20% in chemical combination. In its manufacture, chemically com bined water is removed from the gypsum rock by means of a controlled calcination procedure. Then as water is added at the job. the material crystallizes (sets), reverting to its original chemical composition. Gypsum Plasters arc specifically formulated to control setting lime and other important characteristics. This depends upon the intended method of application, the cli matic conditions of the area in which they will be used, and their intended use. USG Basecoat Plusicrs can be applied by using either hand or machine methods, on gypsum or metal lath; gypsum, clay, or concrete tile; concrete or cinder blocks; brick, or other approved plaster bases. FUNCTION & UTILITY Basecoat plasters provide a plastic working material which will conform to most designs and provide the ultimate in durable wulls and ceilings. Flre-Protcctlon -- Gypsum plaslcr, properly proportioned with approved aggregates, and used in conjunction with specific plaster bases, provides excellent fire-protection. (See pages 12 & 13 of AIA File 20 for "Fire Test Data") Strength--There are significant differences in the strengths of gypsum basecoat plasters. The strength of a gypsum basecoat plaster is dependent on four factors: 1. U'oter-Ccnient Ratio--The water required to produce a plastic mix depends on the amount and type of Bggrcgaie. (See technical data page 3) 2. Control of Set-- Rtr> Top Gypsum Plasters are formu lated for use with market aggregates, climatic condi tions, and job conditions. The quicker a gypsum plaslcr sets, the stronger the basecoat. 3. 77/rre ofApplication -- Plasters should be applied within one hour niter mixing to assure desired strength and proper bond. 4. Ventilation and Drying are important adjuncts to producing a strong basecoat once the gypsum plaster has set. Not only must the plaster be dried, but the water must be removed from the building. Sound Isolation--Gypsum plaster in combination with lathing or construction systems offers sound transmission loss char acteristics suitable fur most requirements. Sanded basecoat plasters provide llic optimum results. u o -F CP o *T. M. R*0. U.S. Pat.

Since the finish coat must be compatible with the basecoat care must be taken in the selection of (he finish coat materials in relationship with the characteristics of the basecoat. There are three general classifications of finishing materials: 1. Prepared finishes 2. Smooth trowel finishes 3. Sand float finishes FUNCTION i UTILITY The finish coat serves as a leveling coal, as a base for decora tion and provides the required resistance to abrasion. Gauging plasters impart an early hardness and strength, minimizing the shrinkage characteristic of lime. Tor machine application.
