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.

1. A method of using a joint compound, the method comprising: applying a first layer of a joint compound composition to a drywall surface, the joint compound composition comprising water; from 25% by weight to about 95% by weight filler;from 1% by weight to 45% by weight binder; anda dust reducing additive comprising at least one of wax, oil, surfactant, pitch, paraffin, terpene, and glycol;wherein the joint compound composition comprises from 1.5% by weight to 6% by weight of the dust reducing additive;allowing the composition to dry; andsanding the dried composition. 2. The method of claim 1 further comprising applying a tape on the first layer of joint compound composition. 3. The method of claim 2 further comprising applying a second layer of the joint compound composition on the tape. 4. The method of claim 3 further comprising allowing the second layer of joint compound composition to dry. 5. The method of claim 4 further comprising sanding the dried, second layer of joint compound composition. 6. The method of claim 1 further comprising applying the joint compound composition to a joint formed between two adjacent dry wall panels. 7. The method of claim 1, wherein the binder comprises at least one of ethylene vinyl acetate copolymer, vinyl acetate, and polyvinyl acetate. 8. The method of claim 1, wherein the filler comprises at least one of perlite and limestone. 9. The method of claim 1, wherein the dust reducing additive comprises at least one of wax, pitch, paraffin, mineral oil, com oil, tung oil, castor oil, linoleic acid, and terpene. 10.
