In a method for producing a fiber board, particularly a hardened wood fiber board, liquid curing material is applied across the entire surface of a top side of the fiber board, wherein less than 500 ml of curing material are applied per m2. By generating a pressure difference between the top side and the bottom side of the fiber board, the curing material will be sucked and/or pressed in. This makes it possible to produce customizable fiber boards at a later time, into which desired contours and grooves can be formed, wherein the required post-processing is simplified and, thus, the fiber boards can be produced in an inexpensive manner.
