1. A method for producing a building board, comprising one of a wooden material, plastic or a mixture of wooden material and plastic, having a top side and an underside, wherein the method comprises applying a polyurethane layer at least onto the top side, applying a decorative layer imitating a material onto the polyurethane layer, applying a second polyurethane layer after the decorative layer is dried; and, prior to drying the second polyurethane layer, applying a structuring embossing. 2. The method of claim 1, wherein the polyurethane layer is applied by pouring on and smoothing with a doctor's blade or by one or more rolling mills. 3. The method of claim 1, further comprising applying at least one sealing polyurethane layer on the decorative layer and drying at least a last layer of the sealing polyurethane layer by at least one of a heater fan and through airing in ambient air. 4. The method of claim 1, wherein the decorative layer is applied by at least one digital printer or printed in a screen printing process. 5. The method of claim 4, wherein the decorative layer is applied in one layer or in several layers. 6. The method of claim 5, further comprising producing by the decorative layer itself a relief-like surface imitating a pattern of the material. 7. The method of claim 1, wherein a polyurethane layer is applied to the underside. 8. The method of claim 1, further comprising providing a decoration and/or structuring embossing on at least part of side edges of the building board. 9. The method of claim 8, wherein the structuring embossing on the side edges of the building board matches a structure embossing on the top side. 10. The method of claim 1, wherein the second polyurethane layer is thicker than the polyurethane layer, and the second polyurethane layer is composed of several layers. 11. The method of claim 10, wherein an applied amount of the second polyurethane layer is between about 50 to 100 g/m2. 12. The method of claim 10, wherein an applied amount of the second polyurethane layer is between about 100 to 400 g/m2. 13. The method of claim 1, wherein the top side and an underside of the building board are provided with identical layer structures, with the underside including a structuring embossing for antiskid effect. 14. The method of claim 13, wherein a pattern of the structuring embossing on the underside and the top side are matched. 15. The method of claim 1, wherein after active drying of the decorative layer, applying the second polyurethane layer by a roller printing machine, and prior to curing of the polyurethane layer, applying the structuring embossing. 16. The method of claim of claim 1, wherein the structuring embossing is made in a surface of the polyurethane layer which matches a decoration of the decorative layer. 17. The method of claim of claim 1, wherein the structuring embossing is made by a roller printing machine. 18. A method of producing a building board comprising: applying a polyurethane layer on at least on a top side of the building board, which has particles heavier than the polyurethane layer; andapplying a decorative layer onto the polyurethane layer. 19. The method of claim 18, wherein the polyurethane layer contains sand, flour or dusts of quartz, granite or marble or metal particles. 20. The method of claim 18, further comprising applying a second polyurethane layer after the decorative layer is actively dried; and, prior to actively drying the second polyurethane layer, applying a structuring embossing.
