  • Patent number: 9039831
    Abstract: A non-aqueous drywall compound being the combination of a first component mixture of acetone, a non-aqueous liquid adhesive containing ethyl cyanoacrylate, and a powder containing calcium sulfate hemihydrate (plaster of Paris), the mixture being a pliable putty capable of adhering to gypsum wallboard or similar work surfaces. The second component of the drywall compound is an accelerator or activator containing acetone and toluene. The first component is applied to a defect in a work surface using a spreading tool and the second component is then applied to the exposed surface of the first component, such as by spraying or brushing, whereupon the drywall compound cures, hardens or sets within less than ten minutes to a state capable of being sanded into a smooth, hard surface and painted.
