The invention is the interior face attaching mechanisms of a plastic injection molded flow-through grid forming grid panel that is used as a form for concrete/cementitious material. A “T” or nub catch is formed by the plastic injection mold halve sections at the outer ends of interior face extended vertical grids such that during a concrete/cementitious pour the “T” or nub catch, and attached forming panel connecter tie or webs, does not unduly block the flow of the concrete/cementitious material from flowing through the grid openings. The “T” or nub catch enables forming panel tie or web connecters to slide down vertically along the interior face of the concrete/cementitious material flow-through grid forming panel and downward attach to the “T” or nub catch.

Aspects of the disclosure relate to lath/rainscreen assemblies including a sheet defining lath and rainscreen faces, first and second ends, and first and second sides. A plurality of protrusions extend from the rainscreen face and also optionally the lath face. The protrusions on the lath face in combination with the lath face provide a substrate for application of a stucco veneer. If no protrusions are provided on the lath face, the lath face can be secured to siding. The rainscreen face and protrusions of the rainscreen face collectively form channels through which moisture can drain to a weep screen or the like. Each of the lath face and the rainscreen face include area free of protrusions so that multiple lath/rainscreen assemblies can be secured to the structure in an overlapping fashion. Methods of installing and making lath/rainscreen assemblies are also disclosed.

Devices and methods covering a gap between an edge of a surface and a body exposed through an opening in the surface defined by the edge. Such a device has at least first and second sections formed of different materials. The device is positioned so that the second section is over a portion of the surface adjacent the opening and the first section extends over the gap and the opening. After removing a release liner releasably secured to a backside of the first section to cover an adhesive, portions of the first section are bent and molded to plastically conform the portions to the edge of the surface while the second section remains over the portion of the surface adjacent the opening. The body is then contacted with the backside of the first section such that the backside of the first section is adhered to the body with the adhesive.

A plank and plank system for covering a wall or other surface is provided. Each longitudinally extending plank comprises a generally planar front façade and a back member. The back member comprises multiple plateaus interspersed with channels. Each plateau provides a flat surface that will be adjacent to the wall/surface when the plank is installed and onto which, optionally, a strip of pressure sensitive adhesive tape may be applied. The channels provide a predetermined location and predetermined holding capacity to regulate the location and amount of construction adhesive to be applied by a user. In an aspect of the invention, the channels also provide a degree of flexibility that allows the plank to adhere securely to the wall and that allows the depth of the plank to be greater than conventional wood wall covering panels.

The present invention is a masonry support structure and kit. The support structure includes at least a block of cellular glass insulation whose exterior surface is coated in a scratch coat. The support structure may be used to support the application of masonry veneers. The kit includes at least one support structure and may also include masonry veneers, veneer mortar, masonry wall ties, and post brackets.

A plaster composition includes a joint compound/drywall mud and from about 0.5 wt % to about 10 wt % silica (e.g., hydrophilic fumed silica). The plaster composition may be a repair composition. The repair composition may be dispensed as an aerosol using a propellant. The repair composition may be useful for repairing “popcorn” textured ceilings.

The present disclosure relates generally to wallboards, for example, suitable for use in constructing internal walls. The present disclosure relates more particularly to a wallboard and a method that provides simplified high-quality surface finishing. The wallboard includes a wall panel having a front surface and a rear surface. A sandable coating is disposed on the front surface of the wall panel. The method includes positioning wallboards adjacent to one another, applying sandable joint compound over joint formed between the wallboards, and sanding the joint compound and the sandable coating of the wallboards
