An apparatus for repairing cracks, crevices, joints, and other discontinuities in a chimney flue liner, comprises a flexible, resilient applicator having a liquid impervious rubberized coating. An electrical vibrator is installed within the applicator, for tamping the mortar or grout material into any discontinuities in the flue liner. A method of using the apparatus is also disclosed, comprising drawing the applicator downwardly through the flue from top to bottom, connecting the vibrator to a suitable source of electrical power, placing the applicator at the bottom end of the flue, pouring mortar or grout material into the chimney from the top with the mortar flowing to the sides of the applicator and between the applicator and flue liner, and drawing the applicator upwardly through the flue liner while operating the vibrator to coat the interior of the flue liner and tamp the repair material thoroughly into any discontinuities in the liner.
