Abstract
A method and apparatus for applying drywall compound to an irregularity in a wall surface. The drywall compound is formulated to be flowable and placed into an aerosol container with a propellant material. A valve assembly is arranged to allow or prevent fluid flow from the aerosol container. When the valve assembly is opened, the aerosol material expands to force the drywall compound out of the container. A scraper member is arranged on the container to facilitate smoothing of the drywall compound; preferably, the scraper member comprises a scraper edge that is arranged adjacent to an exit opening such that the drywall compound can be dispensed and scraped at the same time.
