Abstract

A masking barrier, and methods of using the masking barrier are described. A releasable barrier for masking walls is disclosed. More particularly, the systems and method in one aspect include a barrier sheet including a boundary or edge adapted with an assembly including an adhesive. In another aspect, the invention relates to the use of an assembly including a pressure-sensitive adhesive area. In another aspect, a release sheet is removably affixed to the pressure-sensitive adhesive area.

Claims

1. A masking barrier comprising:

a. a barrier sheet; and

b. a T-shaped edge assembly extending from an edge of said barrier sheet comprising;

i. a first extension having a first face and a second face;

ii. a second extension having a first face and a second face;

wherein the first extension and second extension extend from the barrier sheet in opposing directions to form said T-shaped edge assembly;

wherein said barrier sheet extends from said T-shaped edge assembly at a substantially center location between the first and second extensions and extends a length that is at least five times a width of the T-shaped edge assembly;

wherein each of said first faces of said first and second extensions are configured opposite the barrier sheet;

wherein each of said first faces of said first and second extensions comprises a pressure sensitive adhesive having a release sheet configured over said adhesive;

wherein at least one of said release sheets comprises measuring lines; and

whereby when said edge assembly is attached to a surface with both the first and second extensions attached by the pressure sensitive adhesive, a force on the barrier sheet, substantially perpendicular to said surface, will create opposing shear forces between said extensions.

2. The masking barrier of claim 1, wherein the barrier sheet comprises a first sheet layer and a second sheet layer attached over at least a portion of the barrier sheet.

3. The masking barrier of claim 2, wherein at least one of the first extension and second extensions comprises a sheet layer of the barrier sheet.

4. The masking barrier of claim 1, wherein a pressure sensitive adhesive is configured on each of said second faces of said first and second extensions.

5. The barrier for masking of claim 4, wherein a release sheet is configured over the pressure sensitive adhesive.

6. The masking barrier of claim 1, wherein the edge assembly is a Y-Shaped edge assembly comprising:

a. a first extension having a first side and a second side;

b. a second extension having a first side and a second side;

wherein the first extension and second extension extend from the barrier sheet at an angle to form a Y-shaped edge assembly, and wherein adhesive is configured on at least a side of both the first and second extensions.

7. The masking barrier of claim 1, wherein measuring lines are configured over a portion of the edge assembly.

8. The masking barrier of claim 7, wherein measuring lines are configured on a peel-off backing configured over the adhesive.

9. The masking barrier of claim 1, wherein the release sheet comprises a plurality of peel-off backings configured on the adhesive.

10. The masking barrier of claim 9, wherein a first peel-off backing is configured over the first extension and a second peel-off backing configured over the second extension.

11. The masking barrier of claim 1, wherein the barrier sheet comprises a plurality of perforations configured in a line to allow the barrier sheet to be separated along the line of perforations.

12. The masking barrier of claim 1, wherein the adhesive has a length and a width, and a line is configured substantially centered across said width and extending the length of the release sheet, whereby the edge assembly can be aligned in a corner.

13. The masking:

barrier of claim 1, wherein the barrier sheet is configured for attachment to an inside corner feature, wherein the first extension of the T-shaped edge assembly extends along a first portion of said inside corner feature and the second extension extends along a second portion of said inside corner feature.
