ABSTRACT:
A gypsum board sanding device which is adapted to be coupled to a vacuum cleaner for significantly reducing the dust problem created when sanding the joint cement. A sanding paddle is provided which is adapted to support a sheet of sandpaper, the paddle having a plurality of pedestals defining air passages between the non-abrasive side of the sandpaper and the base from which the pedestals project. A hollow tubular handle is joined to the paddle with the interior opening of the handle communicating with a hole formed through the thickness dimension of the paddle. Means are provided for fastening a conventional vacuum cleaner to the handle whereby dust and other debris generated during the sanding operation is drawn from the periphery of the sanding paddle into a dust collection reservoir.
