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.
A wall repair compound including a dust reducing additive.
An initially paste-like mixture for filling joints between adjacent wallboard panels, and repairing cracks, holes, or other imperfections in a wall surface, said mixture including a sufficient amount of a dust reducing additive so that the mixture, when allowed to harden and sanded, generates a quantity of airborne particles having a size of less than 10 microns when tested as described in this specification which is 50% less than the quantity of airborne particles that would be generated by said mixture without said dust reducing additive.
An initially paste-like mixture for filling joints between adjacent wallboard panels, and repairing cracks, holes, or other imperfections in a wall surface, said mixture including a sufficient amount of a dust reducing additive so that the mixture, when allowed to harden and sanded, generates a quantity of airborne particles having a size of less than 10 microns when tested as described in this specification which is less than 50 mg/m3.
A hardenable mixture having an initially paste-like consistency for filling and repairing cracks, holes, or other imperfections in a surface, said mixture including a sufficient amount of a dust reducing additive so that when the hardened mixture is tested as described in this specification, the quantity of airborne particles having a size of no greater than 10 microns is at least 50 percent lower than the quantity of airborne particles that would be generated if the mixture contained no dust reducing additive.
A dust reducing additive composition for admixing with a drywall joint compound, said drywall joint compound comprising a filler and a binder, said additive comprising at least one of a wax, oil, surfactant, solvent, and mixtures thereof.
A method of reducing the quantity of dust generated while sanding or otherwise finishing a hardened conventional drywall joint compound comprising the step of mixing a predetermined quantity of a dust reducing additive with the joint compound prior to applying the joint compound to a wall surface.
A drywall joint compound comprising:
