Wood flooring is described, which provides resistance to surface liquids by reducing or eliminating checking on the surface of the wood and transmission liquid through the seams in an installed wood floor. This is achieved by combining a surface coating, a wood veneer and core or solid wood, a tongue and groove profile, and application of a sealer along the tongue and groove or locking profile.

A vertical joint system for substrates is formed with joints and which engaged by relative motion in a direction perpendicular to major surfaces and of the substrate. The joints are configured to enable relative rotation of up to 3 degrees while maintaining engagement of the joints. The joints and are further configured to form two locking planes one on each of the inner and outer most sides of the joint. Engagement about the locking planes is provided by transverse outward extending surfaces. At least one surface in each pair of engaging surfaces is smoothly curved. The joints and can be further arranged to provide a third locking plane parallel to and between the locking planes. The joints are disengaged by combination of a downward rotation of one joint relative the other then application of a downward force.

A method is provided for manufacturing a paper layer having a printed pattern for use in panels that at least include a substrate and a top layer. The top layer includes the paper layer. The method may involve providing the paper layer with an inkjet receiver coating by transporting the paper layer relative to a coater in a coating direction. The coated paper layer may be provided with at least a portion of the printed pattern using a digital inkjet printer that includes a housing containing print heads. Providing the printed pattern may involve using water based pigment containing inks. The printed pattern may include a wood motif having wood nerves extending generally in a nerve direction substantially corresponding to the coating direction. Providing the printed pattern may involve a relative motion between the digital inkjet printer and the paper layer during a printing operation in a printing direction substantially corresponding or substantially opposite to the coating direction. The paper layer may be maintained flat inside the housing, or the minimum radius over which the paper layer is bent inside the housing may be larger than 25 centimeters. The paper layer may be fed from a roll, printed upon, and rolled back up again.

Waterproof engineered floor and wall planks have a veneer layer bonded with a plastic composite core, and an underlayer, preferably an underlayer of cork.

Various embodiments of tiles or devices that are used to create a structure used to cover a floor other surface are described. Preferred tiles or devices comprise one or more magnetized surfaces that may comprise one or more magnets or ferrous material. The magnetized surfaces can be used to magnetically couple adjacent tiles or devices to form the flooring or other structure. In some embodiments, the tiles or device may comprise one or more routed edges.

Described is a set of panels (1,2), each panel comprising: ⋅ a top surface (5) and a bottom surface (4); ⋅ a first edge (6) and a second edge (7) parallel to the first edge (6), said edges (6, 7) extending between said top and bottom surfaces (5, 4); ⋅ a first groove (10) provided in the bottom surface (4) of each panel, said first groove (10) extending parallel to and along the first edge (6) of the panel; ⋅ a second groove (11) provided in the bottom surface (4) of each panel, said second groove (11) extending parallel to the first groove (10) along the second edge (7) of the panel; ⋅ a locking profile (3) allowing locking a first panel (1) with its first edge (6) to the second edge (7) of a second panel (2), said locking profile (3) comprising a base (16) and at least three protruding rims (17, 18, 19) extending parallel to one another in the longitudinal direction of the locking profile (3), a first rim (17) pressed in the first groove (10) of a first panel (1) and a second rim (18) situated in between the first and third rims (17, 19) of each locking profile (3) and cooperating with a part of the first panel (1) such that a section (13) of the bottom surface (4) of the first panel (1) is clamped between the first rim and the second rim (17, 18) of the locking profile (3), the third rim (19) configured to fit in the second groove (11) of a second panel (2) thereby locking the second panel (2) to the first panel (1), characterised in that at least the second rim (18) is continuous along the entire length of the locking profile (3). Further described is a method of manufacturing the set of panels.
