Abstract: A water-soluble texture enhancing composition, including a base powdered composition including powdered calcium carbonate, and a soluble packaged bleach, provided in sufficient quantity so that upon mixing with the base composition and water to form an aqueous slurry, and being agitated, the bleach provides an anti-microbial function for an extended period, preferably up to 80 hours. Also, a process for preparing a textured composition is provided, including providing a base powdered texture composition, providing soluble packaged bleach and mixing same with the base composition, and adding water to create an aqueous slurry, the soluble packaged bleach being provided in sufficient amount for inhibiting microbial growth in the solution for an extended period, preferably up to 80 hours.

Abstract: Method of making foamed gypsum slurry having 15 to 90 volume percent gas bubbles including: passing first slurry including water and on dry basis 50 to 98 wt. % calcium sulfate hemihydrate, 1 to 50 wt. % calcium carbonate, and 0.1 to 10 wt. % cellulose thickener via a first hose to a Wye connector conduit first inlet opening at Rate C and passing alum solution via a second hose to a second inlet opening of the conduit at Rate D to create combined mixed stream passing from the conduit to a static mixer for mixing for Time 3 to activate at least a portion of the calcium carbonate and alum to generate CO2 and create the foamed gypsum slurry; transferring the slurry from the mixer to a cavity between two wall boards via a third hose. Allowing the slurry in the cavity to expand, harden and dry.

Abstract: Methods of treating lime bucking in a plaster slurry are described. The method involves providing a slurry exhibiting lime bucking having a cone penetration of less than 10 mm at a consistency of 60 cc, comprising: water; calcium sulfate hemihydrate; and hydrated lime; and mixing an effective amount of a dispersant comprising a low intensity dispersant into the slurry so that the cone penetration increases and wherein the cone penetration is 10 mm or more at 10 minutes after addition of the dispersant at a consistency of 60 cc; and applying the plaster slurry containing the dispersant to a substrate. Veneer plaster dry component mixtures having reduced lime bucking when made into a slurry containing a low intensity dispersant, or hydrated lime coated with wax or a dibenzoate plasticizer are also described.
