A method for manufacturing a floor panel with a substrate and a top layer of laminate, which floor panel, at one or more edges, is provided with a lower edge region, where the laminate extends in one piece from the actual upper surface of the substrate over the lower edge region at least up to a point. The laminate surface is situated at a level in a horizontal plane which intersects the substrate and that the substrate material, at the location of the lower edge region, has the same or a lower density than at the actual upper surface of the substrate material.

A set of essentially identical panels, such as building panels, provided with a mechanical locking system including a displaceable tongue, which is arranged in a displacement groove with a first opening at a first edge of a first panel. The displaceable tongue is configured to cooperate with a first tongue groove, with a second opening at a second edge of an adjacent second panel, for vertical locking of the first and the second edge. The height of the first opening is greater than a second height of the second opening.

A floor panel with a substrate, a decorative layer of wood veneer with a thickness of 1 millimeter or less on the substrate, and a lacquer layer including transparent or translucent surface material on the wood veneer. The lacquer layer can have hard particles. The lacquer layer can extend from the upper surface of the wood veneer at least up to a side edge of the wood veneer, such that the side edge is at least partially covered by the lacquer layer.
