For one-day drywall finishing. For interior gypsum panels and exterior gypsum ceiling boards. Weighs 25% less than conventional setting-type compounds. Sanding ease similar to a ready-mixed, all-purpose joint compound. Unique humidity resistance. Exceptional bond with low shrinkage. Check-crack resistance in heavy fills. Choice of setting times. Compounds are nonasbestos, chemically setting compounds for interior gypsum panels and exterior gypsum ceiling boards, that permit same-day joint finishing, and, usually, next-day decoration. Compounds are lightweight for easy handling and sand easily for fast, smooth finishing. They are ideal for heavy fills and are virtually unaffected by humidity. They provide low shrinkage and superior bond, which makes them excellent for laminating gypsum panels to gypsum panels, to sound-deadening boards, and to above-grade concrete surfaces. In addition, they can be used for filling, smoothing, and finishing interior concrete ceilings and above-grade concrete; for taping and finishing SHEETROCK brand Gypsum Panels, and for finishing joints in exterior gypsum ceiling boards. To meet varying job requirements, a full line has been developed to provide a choice in setting times. The suffix number identifying each joint compound indicates an approximate setting time. For example, SHEETROCK 90 sets in approximately 85-130 minutes. Other setting times available are 20 (20-30 minutes); 45 (30-80 minutes).
