ABSTRACT:
A drywall mud applicator, designed to quickly and easily apply a first layer of mud or mastic material to a joint in preparation for applying drywall tape thereto. The applicator includes a main housing comprising two side plates pivotally connected to an intermediate member. During use, the side plates are centrally aligned over a joint located between adjacent drywall panels so that each side plate is positioned against the adjoining drywall surface. The intermediate member is longitudinally aligned over the longitudinal axis of the joint. Attached to each side plate is a guide member that slides laterally over the side plate's front surface to control the width of the mud applied to the joint. A guide plate locking mechanism is provided for selectively locking the guide members in a desired position on the two side plates. A bellows is connected to the intermediate member and is used to evenly distribute mud to port openings formed on the two side plates.
