An applicator for applying drywall mastic or other material to a flat drywall surface or to an outside drywall joint or other surface comprises a body member having an upper surface and a lower surface and a pair of opposed ends, a recess in the lower surface for connection to a source of the material to be applied to the surface and at least one pair of opposed arms pivotally mounted on one of the sides of the body member for movement between deployed and retracted positions depending on whether the material is being applied to an outside corner joint or a flat surface, respectively. In another embodiment, the applicator has a pair of relatively moveable blades located in operational relationship with respect to each other for controlling flow of the material from the recess to the surface to which it is being applied. |
