Method for producing a wooden composite material board, in particular an MDF or HDF board

A method for producing a wood-based board by scattering a mat of wood fibers or wood chips wetted with a first binder, which is subsequently pressed in a hot-press to form a board of desired thickness, the pressing being preceded by the scattered application, to a top side of the mat, of a powder mixture of color pigments and a second binder as priming agent, wherein the mat, after the scattered application of the powder mixture, is sprayed with water in an amount of 10 to 30 g/m2, on the powder mixture of color pigments and the second binder, prior to the pressing to form the wood-based board, wherein a steam pulse is developed during the pressing due to the spraying of the water in an amount of 10 to 30 g/m2, and the mat of wood fibers or wood chips wetted with the first binder is subjected to a pre-pressing to carry out a precompaction prior to the scattered application and the spraying of the water.
