Abstract

A drywall sealing tape which includes a substrate layer and a mesh layer made of mesh filament. The mesh layer is an array of filaments formed together which, when adjacent the substrate, create an inter-filament cavity for receiving and retaining joint compound between the substrate and the drywall panel. In use, the drywall sealing tape of the present invention may be coated with joint compound and applied to a drywall panel. The inter-filament cavities retain a volume of joint compound corresponding to the approximate thickness of the mesh filament. The joint compound retained within the cavities serves to bond the drywall sealing tape of the present invention to the drywall panels, and provides a seamless, crack-resistant surface.

Claims

1. A drywall sealing tape, comprising:

a substrate having a surface; and

a mesh layer adjacent the surface of the substrate, the mesh layer further comprising an array of filaments which, together with the substrate, define a plurality of inter-filament cavities to receive joint compound.

2. The drywall sealing tape of claim 1, and further comprising an adhesive coating on the mesh layer.

3. The drywall sealing tape of claim 1, wherein said substrate is made from paper.

4. The drywall sealing tape of claim 1, wherein said substrate is made from a polymer.

5. The drywall sealing tape of claim 1, wherein said filaments are made from nylon.

6. The drywall sealing tape of claim 1, wherein said filaments are made from glass fibers.

7. The drywall sealing tape of claim 1, wherein said filaments are made from a synthetic material.

8. The drywall sealing tape of claim 7, wherein said synthetic material is a rigid vinyl.

9. The drywall sealing tape of claim 1, wherein said filaments are made from metal.

10. The drywall sealing tape of claim 9, wherein said filaments are coated with a corrosion-resistant coating.

11. The drywall sealing tape of claim 1, wherein said surface of said substrate is substantially covered by said mesh layer to define two longitudinal side strips.

12. The drywall sealing tape of claim 11, wherein said longitudinal side strips are pliable.

13. The drywall sealing tape of claim 1, wherein said substrate is coated with a joint-compound bonding material.

14. The drywall sealing tape of claim 1, wherein said mesh layer is coated with a joint-compound bonding material.

15. The drywall sealing tape of claim 1, wherein said inter-filament cavities have dimensions of approximately 0.10 inches wide, 0.10 inches long, and 0.025 inches thick.

16. A drywall sealing tape for sealing joints between a first drywall panel and a second drywall panel, comprising:

a substrate having a surface; and

a pattern of protrusions extending from said surface to form a plurality of cavities.

17. The drywall sealing tape of claim 16, wherein said pattern of protrusions is a checkerboard pattern.

18. The drywall sealing tape of claim 16, wherein said protrusions extending from said surface are formed from said substrate.

19. The drywall sealing tape of claim 16, wherein the protrusions extending from said surface are embossed in said substrate.

20. The drywall sealing tape of claim 16, wherein said protrusions are applied to the surface of said substrate.

21. A drywall panel assembly, comprising:

a first drywall panel;

a second drywall panel adjacent to and coplanar with said first drywall panel to define a seam therebetween; and

a length of drywall sealing tape comprising a substrate having a surface, a mesh layer on the surface to define a plurality of cavities, and a coating of joint compound on the surface and within said plurality of cavities.
