A wallboard joint compound package is provided, including a container defining an interior space and configured for being sealed, a first component of ready-mixed joint compound being disposed in the interior space to a level which leaves a pre-determined head space, and an upper surface of the component is defined in the container. A second component is provided, including water, and is placed in the interior space upon the upper surface, such that the first and second components remain substantially distinct prior to opening of the container.

1. A wallboard joint compound package, comprising: a container defining an interior space and configured for being sealed;a first component of homogeneous ready-mixed joint compound being disposed in said interior space to a level which leaves a pre-determined head space, and an upper surface of said component is defined in said container; anda second component including water is placed in said interior space upon said upper surface, such that said first and second components remain substantially distinct prior to opening of said container. 2. The package of claim 1 wherein said second component is a blend of water and a preserving agent. 3. The package of claim 2 wherein said preserving agent is taken from the group consisting of a bacteristat, bleach and a disinfectant. 4. The package of claim 1 wherein said ready-mix joint compound is a paste-like blend of water and at least one of a filler; a binder, a thickener, a suspending agent, a biocide, a preservative, a mineral filler and expanded perlite. 5. The package of claim 4 wherein said filler is at least one of calcium carbonate or calcium sulfate dehydrate, comprising approximately 50-95% of the dry weight of the composition. 6. The package of claim 4, wherein said binder is a latex emulsion binder comprising approximately 0.5-10% of the dry weight of the composition. 7. The package of claim 4, wherein said thickener is a cellulosic thickener comprising 0.1 to 3.0% of the dry weight of the composition. 8. The package of claim 4, wherein said suspending agent comprises 1.0 to 10% of the dry weight of the composition. 9. The package of claim 4, wherein said expanded perlite comprises 1.0 to 10% of the dry weight of the composition. 10. The package of claim 1, wherein said second component acts as a barrier layer to prevent exposure of said upper surface to air. 11. The package of claim 1, further including a lid for sealing said container. 12. A wallboard joint compound package, comprising: a container defining an interior space and configured for being sealed with a lid;a first component of ready-mixed joint compound being dispensed in said interior space to a level which leaves a pre-determined head space, and an upper surface of said component is defined in said container, said first component is a paste-like blend of water and at least one of a filler; a binder, a thickener, a suspending agent, a biocide, a preservative, a mineral filler and expanded perlite; anda second component of a blend of water and a preserving agent is placed in said interior space upon said upper surface, said preserving agent is taken from the group consisting of a bacteristat and a disinfectant, said first and second components remain substantially distinct prior to opening of said container. 13. A method of preparing a joint compound package, comprising: providing a joint compound container;preparing a ready mixed joint compound;adding the joint compound to the container such that a head space is defined between an upper surface of the joint compound and an upper edge of the container;adding an amount of water on top of the upper surface of the ready mixed joint compound; andclosing the container. 14. The method of claim 13, further including determining the amount of water to be added within the container as a top layer or phase by measuring the viscosity of the ready mixed joint compound paste before the water is added, and the correct amount of water is added such that after drill mixing and blending the two phases together will result in a thinned down joint compound being at a desired low viscosity value in the range of less than 400 BU.
