The present invention is directed to the provision of premixed aqueous compositions which are used to provide a paint composition of varying finish characteristics at the point of sale. Thus, the merchant distributing the paint composition made from the subject premixed compositions need only maintain inventory of four compositions. The particular compositions which are the subject of the invention exhibit stable characteristics during storage in their respective reservoirs. The compositions include a pigment composition, a dispersant thickening agent, a high resin content binder, and a low resin content binder. The compositions are combined in differing amounts to produce paint compositions being suitable for either interior or exterior use and having differing sheens, quality levels, and color bases.

The invention claimed is: 1. A method of producing an aqueous paint composition, comprising: mixing a first aqueous composition, the first aqueous composition selected from a group of aqueous compositions consisting of a pigment composition, a dispersant thickening agent, a high resin content binder, and a low resin content binder; mixing a second aqueous composition, the second aqueous composition selected from the group of aqueous compositions, the second aqueous composition being a different one of the group of premixed aqueous compositions than the first aqueous composition; storing the first aqueous composition in a first supply reservoir; storing the second aqueous composition in a second supply reservoir; supplying the first aqueous composition from the first supply reservoir to an unfilled receiving reservoir; and supplying the second aqueous composition from the second supply reservoir to the receiving reservoir after supplying the first aqueous composition to produce the aqueous paint composition. 2. The method of claim 1, wherein the step of storing the first aqueous composition comprises storing the first aqueous composition for at least one day, and wherein the step of storing the second aqueous composition comprises storing the second aqueous composition for at least one day. 3. The method of claim 1, wherein the step of storing the first aqueous composition comprises storing the first aqueous composition for at least one week, and wherein the step of storing the second aqueous composition comprises storing the second aqueous composition for at least one week. 4. The method of claim 1, further comprising the steps of: mixing a third aqueous composition, the third aqueous composition selected from the group of aqueous compositions, the third aqueous composition being a different one of the group of premixed aqueous compositions than the first aqueous composition or the second aqueous composition; mixing a fourth aqueous composition, the fourth aqueous composition selected from the group of aqueous compositions, the fourth aqueous composition being a different one of the group of premixed aqueous compositions than the first aqueous composition, the second aqueous composition, or the third aqueous composition; storing the third aqueous composition in a third supply reservoir; and storing the fourth aqueous composition in a fourth supply reservoir. 5. The method of claim 4, wherein the first premixed aqueous paint composition is the pigment composition. 6. The method of claim 5, wherein the second premixed aqueous paint composition is the dispersant thickening agent. 7. The method of claim 6, further comprising the step of supplying the third aqueous composition from the third supply reservoir to the receiving reservoir. 8. The method of claim 7, further comprising the step of supplying the fourth aqueous composition from the fourth supply reservoir to the receiving reservoir. 9. The method of claim 8, wherein the pigment composition comprises titanium dioxide in the range of 40 to 50 percent, water of about 25 percent, a mixture of clay and silica of about 15 percent, a viscosity controlling agent of about 10 percent, and a combination of dispersant and thickener in an amount of less than 5 percent, said percentages being based on weight of the pigment composition. 10. The method of claim 9, wherein the dispersant thickening agent comprises water in an amount of about 93 percent, a phosphate-based dispersant in an amount of less than 1 percent, a cellulosic thickener in an amount of about 1 percent, and a coalescent in an amount of 4 to 5 percent. 11. The method of claim 10, wherein the high resin content binder comprises resin in an amount of about 80 percent, water at about 15 percent and a coalescent at about 2 percent. 12. The method of claim 11, wherein the low resin content binder comprises about 50 percent resin, about 28 percent water, about 7 percent flattening agent, about 11 percent limestone, and about 3.5 percent calcined clay. 13. The method of claim 1, further comprising the step of mixing the aqueous paint composition.
