A method for coating a board of wood-based material, comprising the steps of providing a board of wood-based material; applying a first liquid coating; applying at least a second liquid coating onto the still wet first coating, so that a partial mixture of the coatings takes place; curing the applied coatings by means of radiation, wherein the coatings are selected so that the cured resultant coating has a hardness gradient wherein the hardness of the resultant coating decreases with increasing depth viewed from the surface of the resultant coating.
