Abstract
A method of covering an anomaly in a wall substantially to match a pre-existing texture pattern surrounding the anomaly. The method comprises the following steps. A valve is supported on a container assembly to define a main chamber. Contained material comprising wall material concentrate and propellant material is disposed within the main chamber. An actuator relative is arranged relative to the container assembly such that displacement of a button relative to the valve changes the valve from a closed configuration to an open configuration in which a portion of the propellant material is allowed to force the contained material out of the main chamber through the outlet. A first portion of the contained material is applied to the anomaly by directing the outlet at the anomaly and displacing the button. Optionally, a second portion of the contained material may be applied to the base coat by directing the outlet at the base coat and displacing the button. If applied, the second portion of the contained material forms a desired texture pattern on the base coat that substantially matches the pre-existing texture pattern.
