Abstract:
1. A method for producing a floor covering panel by coating a floor board of wood-based material, comprising the following steps: a) providing a floor board of wood-based material; b) applying a first liquid coating composition; c) applying at least a second liquid coating composition onto the first coating composition while the first coating composition is still wet, so that a partial mixture of the coating compositions takes place; d) curing the applied coating compositions by means of radiation to form a floor covering panel; wherein the first and the second coating compositions are polymer-forming compositions, wherein the second coating composition comprises more C═C double bonds than the first coating composition so that the cured resultant coating has a hardness gradient, and wherein the hardness of the resultant coating decreases with increasing depth viewed from the surface of the resultant coating.
