Abstract: The disclosure relates to a method for producing a wooden composite material board, in particular an MDF or HDF board, wherein a cake made of wood chips or wood fibres wetted with a binder is spread, which is subsequently pressed in a hot press to form a board of a desired thickness, wherein, before the pressing, a mixed powder made of colour pigments and a second binder is spread onto an upper side of the cake as a primer, wherein the cake is sprayed with water after the spreading of the mixed powder.
