1. A method for producing a building element, comprising:
providing a substrate,
applying a thermosetting binder on the substrate or on a wood veneer layer,
arranging the wood veneer layer on the substrate with the thermosetting binder intermediate the substrate and the wood veneer layer,
arranging an elastic sheet comprising a polymeric material between the wood veneer layer and a press surface of a pressing device,
applying heat and pressure by the pressing device on the elastic sheet, the wood veneer layer, the thermosetting binder, and the substrate, thereby forming a building element comprising the substrate and the wood veneer layer attached to the substrate by the thermosetting binder,
after applying the heat and pressure, removing the elastic sheet from the wood veneer layer.
