Abstract:
A joint tape to be applied to wallboard is provided and includes a base substrate having opposing sides. In certain embodiments, a first adhesive layer is applied to one of the sides of the base substrate and a second adhesive layer is applied to the first adhesive layer, where the first adhesive layer is different than the second adhesive layer, in preferred embodiments the second adhesive being activatable by water. In certain other embodiments, two different adhesives are used in a single adhesive layer. In use, the joint tape is positioned over and removably secured to a joint or corner between adjacent wallboard panels using the first adhesive layer. After the joint tape is in position, joint compound is applied to the joint tape, and the water in the joint tape activates it to form a secure bond with the wallboard panels.
Abstract:
Provided are compositions and methods for expeditious wall installation by spray-applying a joint compound comprising a polymeric binder and hollow spheres. The wet drying-type joint compound for spray application is substantially free of setting minerals, bulk filler, clays, starch, mica, Ca(Mg)C03, expanded perlite, gypsum, talc, diatomaceous earth. It has a shrinkage 250 psi (ASTM D3102-78) and a density of 0.04 - 1.1 g/cm3. The hollow spheres are selected from the group consisting of lime boro-silicate, polystyrene, ceramic, recycled-glass, expanded glass, and lightweight polyolefin beads, thermoplastic, thermoset, and any combination thereof. This joint compounnd is used in a wall installation method comprising joining two gypsum boards together such that the edges create a seam and spraying the seam with the drying type joint compound until the seam is filled.

Abstract:
A joint compound container including a base member (12) having a sidewall (14) and a bottom wall (16) defining an interior space with an open top end where a surface of the sidewall includes an indicator (30). A cover (34) is attached to the top end of the base member and a designated amount of base compound (22) is stored in the interior space of the base member. In use, the cover is removed from the base member and water (21) is added into the interior space of the base member until a level of the water reaches the indicator.
