Abstract: A ready-mixed setting type joint compound in which formation of gypsum seeds has been inhibited. A method for controlling a setting reaction by mixing a ready-mixed setting type joint compound with one or more metal ion control agents comprising aminopolycarboxylic acid and/or a salt thereof, and further mixing the setting type joint compound with one or more non-calcium phosphate compounds. The method may further comprise mixing the setting type joint compound with a set activator obtained by blending together a first set activator including a cadmium compound, lead compound and/or zinc compound and a second set activator including a ferrous compound, aluminum compound and/or manganese compound.

Abstract: An improved resilient wallboard channel constructed and arranged for attachment to a surface of a framing member and accommodating standard fasteners. Included on the present channel is a first, generally planar surface having an elongate edge, an inclined web disposed along the elongate edge and projecting at an oblique angle relative to the first surface, a web edge of the inclined web opposite the first surface is shared with a second, generally planar surface, a stop flange, which is shorter than the inclined web, projects from a stop flange edge of the second surface opposite the inclined web, and the first surface and the web edge are separated by at least ¾-inch measured normally from the framing member surface.

Abstract: A method can include: hot milling a mixture comprising calcium sulfate dihydrate and about 5% to about 25% sucrose by weight of the calcium sulfate dihydrate at a temperature of about 150° F. (66° C.) to about 250° F. (121° C.) to produce a climate stabilizing accelerator (CSA). The CSA produced from this method is dispersed in water and optionally aged for at least 1 minute before use in forming gypsum-fiber composite boards.
