Method for manufacturing decorative cladding building panels and decorative cladding building panels

Abstract

A method for manufacturing a decorative cladding building panel is provided. The method comprises preparing a substrate (1), applying a base layer (2) containing a formaldehyde-free (NAF) binder onto a first surface (4) of the substrate (1), applying a veneer layer (3) onto the base layer (2), and applying heat and pressure to form a decorative cladding building panel. The method further comprises dehydrating the veneer layer (3) before applying heat and pressure to form the decorative cladding building panel, the dehydration of the veneer layer (3) includes applying one or more of IR radiation, heat, microwaves, and / or hot air to the veneer layer (3).
