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.

Claims

1-54. -54. (canceled)

55. A paint mask package for masking a corner area, comprising:

a sheet having 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 sheet includes at least a first inner edge and at least a second inner edge;

said sheet includes an adhesive on said bottom face extending from said first and second outer edges toward said at least first and second inner edges;

said sheet includes a non-adhesive area on said bottom face;

said non-adhesive area extends from said adhesive to said at least first and second inner edges; and

,

a plurality of said sheets being nestled together to form a paint mask package of said sheets.

56. The paint mask package of claim 55, wherein said at least first and second inner edges intersecting at an angle of 90 degrees.

57. The paint mask package of claim 55, wherein said package is selected from the group consisting of a pad, a roll, and a sheet.

58. The paint mask package of claim 55, wherein said top face of each sheet includes release coating and said adhesive on said bottom face of each paint mask sheet releasably engages said top face of the adjacent underlying paint mask sheet.

59. The paint mask package of claim 58, wherein said package is selected from the group consisting of a pad, a roll, and a sheet.

60. A paint mask package, comprising:

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

;

said sheet includes at least a first inner edge and at least a second inner edge;

said sheet includes an adhesive on said bottom face; and

;

a plurality of said sheets being oriented relative to each other and nestled together such that at least a first said sheet and at least a second said sheet are rotated relative to one another thereby providing a paint mask package.

61. The paint mask package of claim 60, wherein said top face of each sheet includes release coating and said adhesive on said bottom face of each paint mask sheet releasably engages said top face of the adjacent underlying paint mask sheet.

62. The paint mask package of claim 61, wherein said package is selected from the group consisting of a pad, a roll, and a sheet.

63. The paint mask package of claim 60, wherein said sheet includes a non-adhesive area on said bottom face.

64. The paint mask package of claim 60, wherein said package is selected from the group consisting of a pad, a roll, and a sheet.

65. A method of masking a plurality of corners in a window frame, comprising:

providing a plurality of sheets, each sheet of said plurality of sheets having opposite bottom and top faces and at least a first and a second outer edge, said at least first and second outer edges intersecting at an angle of 90°

, said sheet includes an inner edge, said sheet includes an adhesive on said bottom face extending from said first and second outer edges toward said inner edge;

applying one said sheet to each corner of a window pane in the window frame; and

,

applying masking tape from a first said sheet inner edge to at least a second said sheet inner edge along an edge of the window frame.

66. The method of masking according to claim 65, further comprising:

applying masking tape from said first said sheet inner edge to a third said sheet inner edge along another edge of the window frame.

67. The method of masking according to claim 65, wherein said sheet includes a non-adhesive area on said bottom face.

68. The method of masking according to claim 67, wherein said non-adhesive area extends from said adhesive to said inner edge.

69. The method of masking according to claim 65, wherein said sheet being L-shaped and having first and second legs that are generally rectangular in shape and at right angles to one another.

70. A method of masking a plurality of corners in a window frame, comprising:

providing a plurality of sheets, each sheet of said plurality of sheets having opposite bottom and top faces and at least a first and a second outer edge, said at least first and second outer edges intersecting at an angle of 90°

, said sheet includes an inner edge, said sheet includes an adhesive on said bottom face extending from said first and second outer edges toward said inner edge;

applying one said sheet to each corner of a window pane defining a line of demarcation in the window frame and adjusting said sheet to account for irregular edges along said line of demarcation;

applying masking tape from a first said sheet inner edge to at least a second said sheet inner edge along at least one edge of the window frame.

71. A paint mask for masking a corner area in a window frame, comprising:

a sheet having opposite bottom and top faces and at least a first and a second outer edge, said at least first and second outer edges intersecting at an angle of 90 degrees;

said sheet includes an adhesive disposed on said bottom face;

said sheet includes an inner edge;

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

,

each said sheet adapted for masking a corner of the window frame wherein a user applies straight sections of masking tape therebetween extending from one said sheet to another said sheet along an edge of the window frame.

72. The paint mask of claim 71, wherein said at least first and second outer edges have a length, said length is less than a length of an associated edge along the window frame.

73. The paint mask of claim 71, wherein each corner of the window frame includes one of said sheets.

74. The paint mask of claim 71, wherein edges of the window frame correspond to said first and second outer edges of said sheet.
