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.

65. The paint mask package according to claim 64, wherein said adhesive include an area extending from said first and second outer edges toward said at least first inner edge;

and,

said adhesive area is greater than said non-adhesive area.

66. A paint mask package for masking corner areas of a window adjacent work pieces to be painted, comprising:

said paint mask package including a plurality of paint mask sheets, wherein each of said plurality of paint mask sheets comprises;

opposite bottom and top faces and a first and a second outer edge, said first and second outer edges intersecting at an angle of 90°

;

said sheets include at least a first inner edge;

said sheets further include at least a second inner edge, said at least first and second inner edges intersecting substantially at an angle of 90 degrees;

said sheets include an adhesive on said bottom face in a band along a majority of said first and second outer edges;

said sheets include a non-adhesive area on said bottom face in a continuous band along said first and second inner edges;

said adhesive extends from said first and second outer edges toward said at least first inner edge;

said sheets being L-shaped and having first and second legs that are generally rectangular in shape and at right angles to one another;

said plurality of paint mask sheets being oriented relative to each other and nestled together to form an unfolded paint mask package of said sheets; and

,

said unfolded package presents each uppermost said sheet for use consisting of grasping with one hand by said non-adhesive area on said bottom face and said top face, for removing from said package, and for same said one-handed positioning and masking of the separate corner areas of the window.

67. The paint mask package according to claim 66, wherein said adhesive area is greater than said non-adhesive area.

68. A paint mask package for masking corner areas of a window adjacent work pieces to be painted, comprising:

said paint mask package including a plurality of paint mask sheets, wherein each of said plurality of paint mask sheets comprises;

opposite bottom and top faces and a first and a second outer edge, said first and second outer edges intersecting at an angle of 90°
