An improved apparatus for applying substances, some of which can be highly viscous in nature, to desired surfaces is disclosed. The applicator (10) can include a housing (12) defining a closed plenum (40) which is filled with a fluid medium. The housing (12) is mounted for rotation about an axis, and an applicator shoe (28) is mounted at a first end (14) of the housing (12). A duct or tubular member (22) is disposed radially inwardly from the shoe (28) with respect to the axis of rotation. Centrifugal delivery conduits (32) are provided to afford fluid communication between an interior passageway (26) of the tubular member (22) and a chamber (38) formed in the shoe (28). As the housing (12) rotates about the axis, substance introduced into the interior passageway (26) of the duct (22) is centrifugally impelled to the shoe (28) through the conduit means (32).
