A method for rapid wall installation is provided by spray-applying the composition and a joint composition comprising a polymeric binder and hollow spheres. The spray-applied wet-dry joint composition is substantially free of hardenable minerals, bulk fillers, clay, starch, mica, Ca(Mg)C03, expanded pearlite, gypsum, talc, and diatomaceous earth. Shrinkage is <15 vol% (ASTM C474-05) and viscosity is adjusted to 15,600-23,000 cP (ASTM C474-05). The joint composition includes 3 to 90 wt% of a radex emulsifying binder selected from acrylic acid polymers, acrylic acid copolymers, alkyds, polyurethanes, polyesters, and epoxy; Up to 5 wt% nonionic surfactant; Up to 3 wt% of wetting agent; And 5-25 wt% of a plurality of hollow spheres. These spheres have self-contained air surrounded by self-contained air surrounded by a solid barrier, average isotropic crush strength> 250 psi (ASTM D3102-78) and a density of 0.04-1.1 g/cm ³ . The hollow spheres are selected from the group consisting of lime borosilicate, polystyrene, ceramic, recycled-glass, foamed glass, and lightweight polyolefin beads, thermoplastics, thermoset plastics, and any combination thereof. Such a joint composition is used in a wall mounting method and the method includes joining two gypsum boards together so that the edges form a joint and spraying the joint with a dry joint composition until the joint is filled.
