A back-up plate is provided for a reversible double-sided rotary buffing pad. The back-up plate is attached directly to the output shaft of the power buffer and the buffing pad is attached to the back-up plate and, when attached, circumferentially spaced fingers on the outer edge of the back-up plate bear on the unused buffing face and prevent excess flexing and premature fracture and failure of the backing disk on the interior of the pad that supports the oppositely disposed buffing faces.
