SHEETROCK® Brand DURABOND® Setting-Type Joint Compounds
-
Designed for one-day drywall finishing.These joint compounds are ideal for laminating gypsum panels to gypsum panels, sound-deadening boards, and above-grade concrete surfaces.
SHEETROCK Brand DURABOND setting-type joint compounds are chemically-setting powder compounds that permit same-day joint finishing and next-day decoration of drywall interiors and exterior soffits. They provide a hard, plaster-like surface when dry and are virtually unaffected by humidity.
The compounds provide multiple applications: filling, smoothing, and finishing interior concrete ceilings and above-grade concrete surfaces; taping and finishing SHEETROCK Brand Mold Tough™ gypsum panels; and taping and finishing FIBEROCK® Aqua-Tough™ tile backerboard under tiles in bathroom wall areas. Other uses include finishing joints in exterior gypsum ceiling boards and presetting veneer plaster finish system joints. They are ideal for heavy fills.
The compounds should be smoothed before setting as they are difficult to sand after drying. They provide low shrinkage and superior bond, which make them excellent for laminating gypsum panels to gypsum panels, sound-deadening boards, and above-grade concrete surfaces.
The compounds are available in a range of formulations that provide a choice in setting times. DURABOND 20 sets in about 20-30 minutes; DURABOND 45 in 30-80 minutes; DURABOND 90 in 85-130 minutes; and DURABOND 210 in 180-240 minutes.
The compounds meet ASTM C475.
