Abstract:
1. A dosage size multi-chambered container having separate sealed compartments and provided with constituent materials for forming a wallboard joint compound, comprising: a flexible body including a top surface and a bottom surface spaced from said top surface, and a first compartment and a second compartment, said first compartment containing a first mixture including calcined gypsum, a set preventer and water from a single, known water source, wherein said water has known properties to reduce the variation of time of set, said first mixture having a first viscosity, said water not being from a water source at a site where the wallboard joint compound is formed; said second compartment containing a second mixture including a set initiator and said water from the single, known water source, said second mixture having a second viscosity, wherein only one of said first and second mixtures includes a rheology modifier; and said flexible body consisting of: a frangible seal having opposing, internal side surfaces extending between the top surface and the bottom surface of the body, the seal being formed between said first compartment and said second compartment, and configured to break upon application of pressure against one of the side surfaces by a user's hand without rupturing said flexible body, and upon breaking of said seal, said first and second mixtures are readily combined by kneading action to provide a dose of the wallboard joint compound contained in said flexible body that is immediately usable on a surface.
