A drywall head for applying mastic compound or other similar material to an outside corner edge of two adjoining drywall board sections to cement on a taped-on corner during drywall assembly. The drywall head includes uniquely constructed flow channels that taper from the leading edge of the tool to the trailing edge of the tool. These uniquely constructed flow channels allow the tool to be used in a uni-directional motion.
