Product Code: 02002I. SHEETROCK® Brand DURABOND® Setting-Type Joint Compounds are chemically-setting powder compounds for drywall interiors and exteriors that permit same-day joint finishing and, usually, next-day decoration. They provide a hard, plaster-like surface when dry and are virtually unaffected by humidity. (They are difficult to sand after drying; must be smoothed before complete setting.) Also ideal for heavy fills. They provide low shrinkage and superior bond, which make them excellent for laminating gypsum panels to gypsum panels, to sound-deadening boards, and to above-grade concrete surfaces.
