SHEETROCK® Brand EASY SAND™ Lightweight Setting-Type Joint Compounds are chemically-setting compounds for interior gypsum panels and exterior gypsum ceiling boards. These powder compounds mix easily with water and weigh 25% less than conventional setting-type joint compounds for easy handling. They provide sanding ease similar to a ready-mixed, all-purpose joint compound. They allow one-day finishing with next-day decoration to ensure rapid job completion and earlier occupancy. The compounds resist humidity for easy application in damp weather when drying-type compounds would delay job completion. For patching applications requiring very quick setting, SHEETROCK® Brand Patching Compound EASY SAND™ 5 has a setting time of 8-12 minutes. These compounds are also excellent for patching and smoothing interior drywall and concrete surfaces because they provide superior bond, low shrinkage and fast setting-action.
