A wall repair compound useful for filling and repairing cracks, holes, and other imperfections in a wall surface includes a conventional filler material, a conventional binder material, and a dust reducing additive which reduces the quantity of airborne dust particles generated when sanding the hardened joint compound. Airborne dust reducing additives include oils, surfactants, solvents, waxes, and other petroleum derivatives. The additive can be added to conventional ready-mixed joint compounds and to setting type joint compounds. A method of reducing the quantity of airborne dust generated when sanding a fully hardened joint compound includes mixing a sufficient quantity of the dust reducing additive with the joint compound prior to when the joint compound has been applied to the wall.

What is claimed is: 1. A method of reducing the quantity of dust generated by a drywall joint compound, said method comprising the steps of a) providing a drywall joint compound comprising filler, water, binder, and at least one of a defoamer, wetting agent, preservative, fungicide, thickener, non-
What is claimed is: 1. A method of reducing the quantity of dust generated by a drywall joint compound, said method comprising the steps of a) providing a drywall joint compound comprising filler, water, binder, and at least one of a defoamer, wetting agent, preservative, fungicide, thickener, non-leveling agent, surfactant, and solvent; and b) subsequently adding a sufficient quantity of dust reducing additive to the drywall joint compound to reduce the quantity of dust generated by sanding the hardened drywall joint compound by at least 50%, wherein if said dust reducing additive comprises a solvent, the solvent evaporates at a rate slower than water. 2. The method of claim 1, wherein when the drywall joint compound of step (a) is allowed to harden and is tested as described in this specification, the joint compound generates a quantity of airborne particles having a size of less than 10 microns which is at least 72 mg/m3. 3. A method of reducing the quantity of dust generated by a drywall joint compound comprising filler, water, defoamer, wetting agent, preservative, fungicide, thickener, non-leveling agent, surfactant, solvent and binder, said method comprising the step of adding a sufficient quantity of dust reducing additive to the drywall joint compound to reduce the quantity of dust generated by sanding the hardened drywall joint compound, wherein if said dust reducing additive comprises a solvent, the solvent evaporates at a rate slower than water. said adding occurring subsequent to the filler, water, defoamer, wetting agent, preservative, fungicide, thickener, nonleveling agent, surfactant, solvent and binder being present in the joint compound. 4. The method of claim 3, wherein the quantity of dust generated by sanding the drywall joint compound prior to adding the dust reducing additive is at least about 72 mg/m3. 5. The method of claim 4, wherein the quantity of dust generated by sanding the drywall joint compound after adding the dust reducing additive is no greater than about 10 mg/m3. 6. The method of claim 3, wherein the quantity of dust generated by sanding the hardened drywall joint compound prior to adding the dust reducing additive is reduced by at least 50% after adding the dust reducing additive. 7. The method of claim 6, wherein the dust reducing additive comprises oil. 8. The method of claim 7, wherein the oil comprises from about 1.5% to about 6.0% of the joint compound total wet weight. 9. The method of claim 1, wherein said dust reducing additive comprises at least one of oil, wax, pitch, paraffin, terpene, and glycol. 10. The method of claim 3, wherein said dust reducing additive comprises at least one of oil, wax, pitch, paraffin, terpene, and glycol. 11. A method of reducing the quantity of dust generated by a drywall joint compound comprising filler, water, thickener, non-leveling agent, and binder, said method comprising: adding a dust reducing additive selected from the group consisting of oils, glycols, waxes, paraffins, terpenes, and combinations thereof, to the drywall joint compound in an amount sufficient to reduce the quantity of dust generated by sanding the resulting drywall joint compound, when hardened, relative to the quantity of dust generated by the hardened drywall joint compound in the absence of said dust reducing additive. 12. The method of claim 11, wherein said dust reducing additive comprises synthetic wax. 13. The method of claim 1, wherein said dust reducing additive comprises synthetic wax. 14. The method of claim 3, wherein said dust reducing additive comprises synthetic wax. 15. A method of reducing the quantity of dust generated by a drywall joint compound, said method comprising: opening a container comprising a dry wall joint compound comprising filler, water, thickener, non-leveling agent, and binder; and adding a dust reducing additive to the joint compound in an amount sufficient to reduce the amount of dust generated by sanding said joint compound, relative to the amount of dust generated by said joint compound prior to the addition of said dust reducing additive, wherein if said dust reducing additive comprises a solvent, the solvent evaporates at a rate slower than water. 16. The method of claim 15, wherein said adding comprises adding from 0.1% by weight to 10% by weight of said dust reducing additive. 17. The method of claim 15, wherein said adding comprises adding from 1.5% by weight to 6% by weight of said dust reducing additive. 18. A method of reducing the quantity of dust generated by a drywall joint compound, comprising the steps of a) providing a drywall joint compound comprising filler, water, binder, and at least one of a defoamer, wetting agent, preservative, fungicide, thickener, non-leveling agent, surfactant, and solvent; and b) subsequently adding a sufficient quantity of dust reducing additive to the drywall joint compound to reduce the quantity of dust generated by sanding the hardened drywall joint compound by at least 50% relative to the quantity of dust generated by sanding the hardened drywall joint compound prior to adding the dust reducing additive, said dust reducing additive comprising oil. 19. A method of reducing the quantity of dust generated by a drywall joint compound comprising filler, water, defoamer, wetting agent, preservative, fungicide, thickener, non-leveling agent, surfactant, solvent and binder, said method comprising the step of adding a sufficient quantity of dust reducing additive to the drywall joint compound to reduce the quantity of dust generated by sanding the hardened drywall joint compound, wherein said dust reducing additive comprises oil, said adding occurring subsequent to the filler, water, defoamer, wetting agent, preservative, fungicide, thickener, nonleveling agent surfactant, solvent and binder being present in the joint compound. 20. The method of claim 19, wherein the oil comprises from about 1.5% to about 6.0% of the joint compound total wet weight.
