摘要： A joint compound including calcium sulfate hemihydrate and/or at least one filler, wherein a total amount of the at least one filler and/or calcium sulfate hemihydrate is at least about 50 wt % of the joint compound on a dry (water-free) basis, preferably the filler comprises calcium carbonate, calcium sulfate dihydrate, or calcium sulfate anhydrite, or a mixture thereof; binder at up to about 15 wt % of the joint compound on a dry basis; polymer thickener at up to about 3 wt % of the joint compound on a dry basis; plasticizer dedusting agent at about 0.01 to about 3 wt % of the joint compound on a dry (water free) basis; and an additive up to about 10 wt % of the joint compound on a dry basis.

摘要： The invention is directed to a joint tape for finishing a joint between boards comprising a nonwoven substrate that does not swell substantially in the presence of water. The invention further provides a method of finishing a joint between boards comprising (i) applying a joint tape of the invention to a joint between boards by embedding the joint tape in a first coat of joint compound, (ii) applying a second coat of joint compound over the tape, wherein step (ii) is carried out before the joint tape and joint compound applied in step (i) have substantially dried, and optionally (iii) applying a third fill or finish coat of joint compound over the tape, wherein step (iii) is carried out before the joint tape and second coat have substantially dried.

摘要： A joint compound system includes a set-inhibited, pre-wetted, setting-type, ready-mix joint compound and a set initiator. The set-inhibited, pre-wetted, setting-type joint compound includes a ready-mixed, setting-type joint compound base with a calcium-free phosphate set preventing agent that impedes chemical hydration of a gypsum component of the setting-type joint compound. The joint compound base is free of calcium carbonate. The set initiator includes alum to reinitiate the chemical hydration reactions.

摘要： Embodiments of a system and a method for evaluating a joint compound specimen can be used to determine a numerical sandability value for the specimen. A moving assembly is configured to move a sanding member in a sanding direction relative to the joint compound specimen supported in a support fixture. An actuator assembly is configured to drive the sanding member into contacting relationship with the joint compound specimen such that the sanding member exerts a controlled amount of pressure against the joint compound specimen. The force gauge is configured to measure a resistance force against the sanding member in a resistance direction in opposing relationship to the sanding direction. A processor programmed with a joint compound analyzing application is configured to use a force signal from the force gauge that is indicative of the resistance force to determine the sandability value for the joint compound specimen.
