A mixing stand device is disclosed for holding a conventional bucket container of a viscous building material in a proper stationary position for mixing. The present mixing stand device comprises a rigid frame assembly erected and attached upon a base platform in a position that allows a worker to stand upon the platform forward of the frame assembly. The frame assembly is formed having an inwardly tapered cylindrical configuration that is fitted to receive the bucket container, the frame assembly comprising upper and lower circular band members spaced apart and coaxially disposed at the respective top and bottom of the frame assembly with a plurality of leg members each being laterally disposed at 90° to the other and extending between the upper and lower band members. Leg members disposed on opposite sides of the frame assembly are formed having an extended tab projecting above the upper band member that align with and engage a pocket formed on either side of the bucket container for the working handle to prevent rotation of the container when seated within the frame assembly.
