An adhesive floor/wallboard includes a floor/wallboard main body layer and a buffer layer adhered to the back surface of the floor/wallboard main body layer. The buffer layer is provided with a plurality of holes. The holes extend through the buffer layer to the main body layer. Glue is deposited in the holes. The buffer layer is adhered to the back surface of the floor/wallboard. The glue in the holes makes direct contact with the floor/wallboard main body at the holes. Due to the holes and their depth, the contact area between the glue, the buffer layer and the main body is increased. Accordingly, the adhesive floor/wallboard can be more firmly adhered to a backing surface.

Expanded metal lath products, or non-metal facsimile products, are disclosed with moisture resistant pressure sensitive adhesive covered by release sheets, and the use of such products in drywall seaming and their manufacture.

The insulating barrier of a panel including has a first stratum and a second stratum, each having a plurality of ridges that face each other, and run athwart of each other. Clearance between at least some adjacent pairs of the ridges provide a mechanical chase that reaches across at least most of the panel. A cladding overlaying at least one side of the insulating barrier is denser than the barrier. The mechanical chase is in the form of a groove through which a utility feed can be routed when the panel is to be mounted in a building.

A decorative wall system is provided that includes a number of panels that can be secured to an underlying wall and to one another in an overlapping configuration to provide a multi-layer, three-dimensional appearance to the wall. In one embodiment of the wall system, the system includes individual panels that include a decorative front surface and a rear surface. The rear surface includes undercuts along each side of the rear surface that can be positioned over the side edges of the front surface of an adjacent wall panel. The panels may each include an adhesive layer including compressible strings therein that assist the adhesive in holding the panel on a surface by forming a vacuum between the panel and the surface to which the panel is attached.

Described are dry cast lightweight veneer blocks and a system and method of installing lightweight veneer blocks. The courses can be assembled without mortar between the courses. As an example, sides of the veneer blocks have areas that recede from an imaginary plane between adjacent veneer blocks to give a deep texturing and a shadow effect between veneer blocks. The installation system and method include a substrate, an air barrier applied to the substrate, a plurality of veneer blocks, and an adhesive applied between the plurality of veneer blocks and the air barrier.

A hard flooring plank and a wall panel plank. The hard flooring plank includes a flooring plank body. A bottom surface of the flooring plank body is bonded with a retractable bonding element. A lower surface of the retractable bonding elements is bonded with a release paper layer. The wall panel plank includes a wall panel plank body. An inner side surface of the wall panel plank is bonded with a retractable bonding element, and the other side surface of the retractable bonding element is bonded with a release paper layer. The hard flooring plank not only overcomes the disadvantage of the hard flooring plank, but also has the advantages of a resilient flooring plank, so that a new breakthrough on the structure of the flooring plank body is achieved.

A multi-layered structure (1) for the production of a floor or wall covering. The structure comprises: a first assembly (E) successively comprising at least: a transparent wear layer (E1) made of polyvinyl chloride; a decorative layer (E2) bonded to the wear layer (E1); a backing layer (E3), bonded to the decorative layer (E2), produced from plasticized and loaded polyvinyl chloride; a foam layer (2), bonded to the backing layer (E3), imparting sound-insulating properties to the structure, and having a lower side. The first assembly (E) comprises a tensile modulus for 1% elongation greater than 5 MPa, and a flexural modulus at 3.5% between 10 MPa and 20 MPa and the foam layer (2) is a cross-linked polyolefin foam layer, having a thickness between 0.5 mm and 2 mm, and a density between 60 kg/m.sup.3 and 120 kg/m.sup.3.

A cement-based artificial stone plate includes a cement-based plate body; and a metal mesh being embedded in the cement-based plate body; wherein the metal mesh is arranged with at least one fixing member, the fixing member defines a screw hole along its axis, and the screw hole of the fixing member is exposed on back of the cement-based plate body, and back of the plate body is provided with regular or irregular protrusions, between any two protrusions forms a groove, and bottom of each groove is close to the metal mesh.

The present disclosure provides tools, systems, and methods for leveling and aligning tiles. A tile leveling tool for guiding installation of tiles on an uneven installation surface comprises: an elongated main body extending along a longitudinal axis thereof, from a first end to a second end, wherein the main body further comprises a flat reference side, wherein the reference side has a straight reference edge parallel to the longitudinal axis; and at least one adjustable spacer extending from the main body configured to extend toward the installation surface, wherein the adjustable spacer is configured to adjust a space between the main body and the installation surface to arrange the reference edge straight across the uneven installation surface and to guide the installation of the tiles evenly.

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.
