Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.

The invention relates to a bamboo floor, in particular to a composite bamboo floor. The composite bamboo floor comprises a floor surface board provided with a body, a pressed surface, a connecting surface connected with the core board, at least one cut surface board side face and surface board end faces, and the core board arranged under the floor surface board and provided with a core board surface connected with the floor surface board, a core board bottom surface, core board side faces and core board end faces, and the positions of the core board side faces or the core board side faces and the surface board side faces are provided with notch structures processed in two sides in the length direction of the composite bamboo floor. The composite bamboo floor is high in strength, high in processing efficiency and low in production cost.

A composition, utility material, and method of making a utility material is disclosed. A composition having an improved setting time may include a plurality of microparticles mixed with a sodium silicate binder and an isocyanate setting agent, where the microparticle composition has a setting time of less than or equal to one hour. A utility material may be a wallboard that includes the composition.

A surfacing product (e.g., flooring element) can be elongate along a longitudinal axis. The surfacing product can have a core having a first surface and an opposed second surface that are spaced along a thickness axis. A veneer can be coupled to the first surface of the core. The veneer can have a first veneer segment that is elongate along the longitudinal axis, a second veneer segment that is elongate along the longitudinal axis, and an insert segment positioned between the first veneer segment and the second veneer segment along the longitudinal axis.

The present invention relates to a floor panel and to a floor. The floor panel according to the invention includes a core provided with an upper and lower surface, and a first and second core flank at a first and second side of the core, respectively. The floor panel includes a first coupling part and a second coupling part provided at the first side and the second side of the core, respectively. Each of the coupling parts includes an inner side flank, an outer side flank, and an upper portion flank connecting the inner side flank to the outer side flank. According to the invention, a portion of the first core flank and an upper portion of the outer side flank of the second coupling part are inclined such that when the floor panel is coupled to an adjacently arranged further floor panel these upper portions lie against each other for the purpose of providing a locking in a vertical direction. In addition, a first upper portion flank of the tongue of the first coupling part includes a curved recess and the groove of the second coupling part may include a bulge complimentary to the curved recess.

Systems and methods directed to the art of installing flooring include untreated flooring planks having a hardwood top surface delivered to a jobsite and including improved thickness tolerances and/or top surface comparative coefficients of friction.

A flooring system includes at least two discrete layers. The at least two discrete layers include at least a first discrete layer comprising variably responsive elastic subfloor. The at least a first discrete layer includes at least first sublayer having area elastic properties and at least a second sublayer, wherein at least a portion of the at least a second sublayer includes a first material displaying dilatant properties. The at least two discrete layers include at least a second discrete layer comprising a wear layer disposed on top of the at least a first discrete layer.

A ballast block is provided with a body and a plurality of fluid receiving channels. The body includes a top surface, a bottom surface positioned opposite the top surface, and a first side extending between the top surface and the bottom surface. The plurality of fluid receiving channels are disposed along the first side in a plurality of units and extending from the top surface to the bottom surface to form a zigzag pattern. Each unit of the plurality of units having an adjacent pair of fluid receiving channels extending at opposing angles toward each other from the top surface to the bottom surface in an approximate V-shape.

The present invention refers to a method for decorating a material comprising the steps of: applying a three-dimensional layer (110) by inkjet printing on at least a part of a support (100). Apply one or more of the following layers on at least a part of the support on which the three-dimensional layer has been created: release layer, texturing layer (120), decorative layer (130), white layer (140), colored layer, functional layer, adhesive layer (150). Apply the transferable decoration on at least part of a material (160) to be decorated. Remove the support (100). Reveal the 3D.

Surface elements comprising a decorative upper layer and a supporting core are disclosed. In such surface elements the decorative upper layer can comprise a digitally applied wood grain pattern made up of at least four colors, said pattern being applied to an underlying white ground coating provided on said supporting core, said pattern comprising at least one of visually simulated knots, cracks, flaws and grain. In such surface elements the decorative upper layer can further comprise an at least partly translucent wear layer arranged over said pattern, said wear layer consisting of a cured substance comprising silicon oxide. In such surface elements the decorative upper layer can further be provided with a surface structure increasing the realism of said wood grain pattern, being directed in accordance with the direction of said pattern and being in the form of narrow elongated recesses simulating the pores of wood.
