A METHOD OF PRODUCING A BUILDING PANEL AND SEMI-FINISHED PRODUCT FOR PRODUCING THE PANEL.

The disclosure relates to a method of producing a building panel (1)， comprising: providing a core (2)， applying a balancing layer (6) having a first moisture content on a first surface (3) of the core (2)， the balancing layer (6) comprising a sheet impregnated with a thermosetting binder， applying a surface layer (12) having a second moisture content on a second surface (4) of the core (2)， the surface layer (12) comprising a thermosetting binder， adjusting the first moisture content of the balancing layer (6) such that the first moisture content of the balancing layer (6) is higher than the second moisture content of the surface layer (12) prior to curing， and curing the surface layer (12) and the balancing layer (6) by applying heat and pressure. The disclosure also relates to a semi-finished product adapted to be cured for forming a building panel (1).
