Abstract: A corner mud applicator pan is provided. The corner mud applicator pan is especially suitable for use in applying beaded mud to corner units for drywall in construction of walls. The applicator pan has a V-shaped opening at the bottom of the pan which has insert guides (or “leads”) which makes insertion of the corner unit into the V-shaped opening easy and efficient. Support lines add strength to the pan and horizontal grip lines increase the grip for the user.
