A method of fastening a wall panel to a wall, according to one illustrative embodiment, comprises coupling a retaining body to a mounting body mounted on an outer surface of the wall adjacent a side edge of the wall panel. Coupling the retaining body to the mounting body may comprise coupling a first connector on an inner surface of the retaining body to a second connector on the mounting body, and positioning a retainer on the retaining body against a retaining surface on the wall panel to fasten the wall panel to the wall. Kits and wall assemblies according to other illustrative embodiments are also disclosed.

An expansion joint profile system for producing an expansion joint in the manufacture of a rigid floor covering includes a profile (1) comprising a first profile element (3) having a first support leg (5) provided for bearing on a substrate (18) and a first abutment leg (6) projecting upwardly therefrom. A second profile element (4) has a second abutment leg (6). A connection element (9) is formed in a ridge-like manner and extends in the longitudinal direction between the two profile elements (3, 4) and connects them to one another in the lower region. An insertion opening (10) is formed between the abutment legs and is open at the top and extends in the longitudinal direction (L). A sealing element (11) is formed in a T-shaped cross-section with a downwardly projecting insertion leg (12) for insertion into the insertion opening (10).

There is disclosed an improved wall panel trim reveal system and method which utilizes a set of vertical, horizontal and corner trim pieces designed to be fitted together. In an embodiment, the system includes horizontal trim pieces having at least one slope, vertical trim pieces having at least one tab forming a slot for receiving one or more horizontal trim pieces therein, wherein the horizontal and vertical trim pieces when installed together with wall panels forming a moisture drainage channel to direct moisture away from the wall.

A wallboard-fastening device secures first and second wallboards to a framing member without fasteners passing through the wallboards. The device includes first, second, and third framing panels joined along lengthwise edges to form a three-sided cup sized to fit around the framing member, first and second flat-spring flanges joined along lengthwise edges to form a front seam, and a channel-dividing panel joined lengthwise to the front seam and to the second framing panel to form first and second channels that receive the first and second wallboards. The flat-spring flanges flex to exert restoring forces on the wallboards that push the wallboards against the second framing panel. The device may be configured for edge joints, outside-corner joints, and inside-corners, and thus may be combined for any type of wallboard installation, including both parallel and perpendicular applications.

The present disclosure relates generally to building surface joint supports, for example, configured to bridge and support the seam between two building surface panels. The present disclosure relates more particularly to a joint support configured to support a joint between building surface panels. The joint support includes a longitudinal support strip including a first end, a second end, a first side edge, a second side edge, an inner surface, and an outer surface. An inner layer of adhesive is distributed over the inner surface of the longitudinal support strip and is configured to bond with a joint compound. The adhesive of the inner layer includes a polysaccharide.

Methods and apparatus are provided for repairing existing structures. A portion of the existing structure is covered with the repair structure. One or more standoffs are coupled to the existing structure to project outwardly away from a surface of the existing structure. One or more cladding panels are coupled to the standoffs by forcing the one or more panels in a direction normal to the surface of the existing structure and into engagement with a standoff connector component of the standoff at a location spaced apart from the existing structure. Curable construction material and/or insulation may be introduced into the space between the cladding panels and the existing structure to provide a repair structure.

A cladding kit is provided for a structure cladding, the structure cladding comprising a first panel that extends away from a structure location along a first surface portion of the structure and a second panel that extends away from the structure location along a second surface portion of the structure. The cladding kit comprises a base piece couplable to the structure at the structure location, the base piece comprising a base connector, and a trim piece comprising first and second wings and a trim connector shaped to make a connection with the base connector to thereby couple the trim piece to the base piece. The first wing is shaped to contact, and be deformed by, the first panel when a connection is made. The second wing is shaped to contact, and be deformed by, the second panel when the connection is made.

A metal lath accessory comprising a metal lath attachment feature that includes a side wall, a first flange extending from the side wall, and a second flange extending from the side wall. The first flange comprises at least one barb that projects from the first flange towards the second flange. In some embodiments, the second flange comprises at least one barb that projects from the second flange toward the first flange. The barbs may be configured to engage a piece of metal lath that is inserted between the first flange and the second flange.

A system for mounting wall panels to an existing wall, includes fastening extrusions, each including an extrusion base section adapted to be secured to the existing wall, at least one retaining wall extending at an angle from the base section, and a holding member on each retaining wall; and intermediary supports for supporting the wall panels at a position between side edges of the wall panels, each intermediary support including an intermediary support base plate adapted to be secured to the existing wall, and a sliding member adapted to be slidably connected with the base plate, such that one wall panel is adapted to be secured on the sliding member for sliding movement relative to the intermediary support base plate with the sliding member in order to slide a side edge of the wall panel into one fastening extrusion between the extrusion base section and the holding member.
