Abstract

The invention relates to a method for producing floor panels, characterized by the following steps: a) scattering glued wood fibers or wood chips to form a wood material cake, b) pressing the wood material cake at elevated temperature to form a large-format substrate plate, which is provided press-finished and has a press skin that arose during the production of the substrate plate at least on the top of the substrate plate, c) applying a base coat made of a liquid melamine-based resin to the upper face of the substrate plate, wherein the resin at least partially diffuses into the top surface layer of the substrate plate and at least partially penetrates and improves the region of the press skin, d) drying the base coat, e) applying a primer to the base coat, f) drying the primer, g) applying at least one water-based paint enriched with pigments in order to produce a decoration, i) applying a seal made of at least one melamine-based resin enriched with wear-resistant particles and cellulose fibers, j) drying the seal, k) applying a base coast made of a liquid melamine-based resin to the lower face of the substrate plate, wherein the resin at least partially diffuses into the lower surface layer of the substrate plate, l) drying the base coat, m) applying a counteracting layer to the lower face of the substrate plate, n) pressing the layer structure under the effect of pressure and temperature, o) dividing the substrate plate into panels of the desired width and length, and p) attaching connecting means and locking elements to opposite side edges in order to connect and lock a plurality of panels without glue to form a floatingly laid floor composite.
