ABSTRACT:
A paint mask particularly adapted for masking corner areas of a demarcation zone to facilitate painting of an area of a workpiece disposed on the other side of the demarcation zone is formed of a thin, flexible sheet having opposite faces. The paint mask includes a first leg and a second leg that are generally rectangular in shape, and the legs intersect to form a right angle adapted for masking a corner and adjacent area. The bottom side of the paint mask which contacts the surface to be masked includes an adhesive for adhering the mask to the workpiece. The top side has release means for releasing stacked paint masks from each other.
