Abstract: A floor panel has a substrate and a decorative layer of wood veneer provided thereon having a thickness of 1 millimeter or less. The substrate has an average density of more than 750 kilograms per cubic meter. The floor panel is rectangular and oblong and comprises a pair of opposite short edges and a pair of opposite long edges. The floor panel, on at least said two opposite long edges, is provided with coupling means allowing that two of such floor panels can be coupled to each other in a vertical direction perpendicular to the plane of the coupled panels and in a horizontal direction in this plane and perpendicular to the respective edge. The wood veneer and/or the substrate immediately underneath the wood veneer is treated at least at the short edges with a fluoro copolymer or a polymeric methylene diphenyl diisocyanate.

Abstract: Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with vertical snap folding that could be accomplished automatically without tools and where the short edge locking system has a tongue made in one piece with the panel. The floor panels may have a first and a second connector at the long edges that are configured to obtain a minimum of friction facilitating a displacement, by a spring back force from the bending of a short edge locking strip, of a new panel in a horizontal direction along the long edge during the vertical snap folding action.
