The present invention provides shelf-stable, non-cementitious dry mix compositions of inorganic non-cementious materials, such as sand, and water redispersible polymer powder (RDP) containing particles of a multi-stage acrylic copolymer having a calcium methacrylate salt group containing alkali-soluble resin outer stage and one or more inner stage, the particles further containing each of one or more nucleating agent having a boiling point of 150° C. to 500° C. and a water solubility of 3.5% or less, and one or more colloidal stabilizer, wherein the colloidal stabilizer and the multi-stage acrylic copolymer are contained in the same RDP particle.
