Methods of making and using the paper substrate, products made therefrom, and uses of the paper substrate are also provided.

The present invention provides a reinforcement tape, the reinforcement tape comprising a plurality of perforations around at least one edge of two opposite edges along a length of the reinforcement tape and a substantially solid portion in between the two opposite edges. Another embodiment of the present invention provides an assembly of a substrate and a reinforcement tape for reinforcement of said substrate. The assembly comprising a layer of a first bonding material applied at said substrate; a reinforcement tape applied at said layer of said first bonding material, said reinforcement tape comprising a plurality of perforations around at least one edge of two opposite edges along a length of said reinforcement tape and a substantially solid portion in between said two opposite edges; and a layer of a second bonding material applied at said reinforcement tape.

An identifiable wallboard joint tape is provided and includes a web of tape incorporated with an identifier such that the tape is visible under UV light and visually distinguishable from the surrounding wallboard joint and joint compound.

A drywall tape including a fiber matrix having a first side and an opposing second side; a sandable coating on at least a portion of the first side of the fiber matrix, wherein the sandable coating is a first color; and, an adhesive element on at least a portion of the second side of the fiber matrix. Additionally, a system for preventing oversanding of surfaces including a matrix having a first side and an opposing second side; and, at least one sandable coating on at least a portion of the first side of the flexible matrix, wherein the sandable coating is a different color than the color of joint compound when dried.

A dry wall tape for use with a panel system includes a mesh having a plurality of width strands, and a plurality of length strands which traverse the plurality of width strands, wherein the length strands are more resistant to a pulling force than the width strands and wherein the tape is configured to be applied to the panel system.

A ceiling system in one embodiment conceals joints between adjoining ceiling panels to provide a monolithic ceiling appearance. The system includes the support structure and ceiling panels each having a top surface, bottom surface, and peripheral edges. In one embodiment, the peripheral edges of the panels may have a hybrid edge detail including a first edge profile and a second edge profile different than the first. A facing material, bonded to the bottom surfaces of ceiling panels after securement to the support structure, has a continuous uninterrupted extent to cover and conceal multiple panels and joints. The facing may be adhesively bonded to the panels.

Sealing element for a waterproof sealing of junctions at structural elements of a building, the sealing element comprising a sealing tape (1) having a waterproof surface and a fabric layer (2) to which a sealing compound can adhere and which is fixed to the sealing tape (1) in a manner so that a portion of the fabric layer (2) projects outwardly from an outer edge (11) of the sealing tape (1), wherein the fabric layer (2) comprises a tear line portion (22; 221, 222) to allow for separating the outwardly projecting portion of the fabric layer (21) by tearing away the outwardly projecting portion of the fabric layer (21).

A joint-sealing tape can be used for sealing a joint between a first building part and a second building part with an elongated carrier and at least two separate sealing strips, which have a round cross section and are disposed on the carrier, spaced apart, side-by-side and running in the longitudinal direction of the carrier.

The present disclosure relates a joint support that includes a support strip having first and second elongate flanges, the first and second elongate flanges having an inside surface, an outside surface, an inner edge, and an outer edge. The joint support further includes a first auxiliary flap including an inner portion attached to the inside surface of the first elongate flange and an outer portion that extends laterally beyond the outer edge of the first elongate flange. The joint support further includes a second auxiliary flap including an inner portion attached to the inside surface of the second elongate flange and an outer portion that extends laterally beyond the outer edge of the second elongate flange. The joint support further includes a pressure sensitive adhesive substance disposed on at least a first portion of an inside surface of each of the first auxiliary flap and the second auxiliary flap.

This invention provides flexible adhesive compositions which can be used instead of joint reinforcement tape for securing a joint seam between abutting panels. Methods using the compositions are provided as well.
