Latex-based formulations for coating and sculpting applications may provide blending a wet mixture with a dry mixture or blending a wet composition with a dry powder. The formulation may then be applied to a surface. In some embodiments, after the formulation is applied to a surface, the formulation may be set to the surface by covering the formulation applied to the surface with a material and/or the formulation may be self-setting on the surface. The formulation may fill gaps in the surface, thereby reducing cracks and shrinkage of the surface. The formulation may be applied to surfaces in a plurality of applications that may include, but are not limited to, sculpting, molding, and cosmetic repairs.
