Abstract

A method of producing a building panel, including: providing a core, applying a balancing layer having a first moisture content on a first surface of the core, the balancing layer comprising a sheet impregnated with a thermosetting binder, applying a surface layer having a second moisture content on a second surface of the core, the surface layer comprising a thermosetting binder, adjusting the first moisture content of the balancing layer such that the first moisture content of the balancing layer is higher than the second moisture content of the surface layer prior to curing, and curing the surface layer and the balancing layer by applying heat and pressure. Also, a semi-finished product adapted to be cured for forming a building panel.
