Abstract:
1. A method for producing panels of a laminar structure comprising: a) making available a large-format, press blank support board of derived timber product which at least on its top has a press skin which has been formed in its production, b) grinding some of the press skin off a top of the support board, c) applying a base coat of a liquid resin based on melamine to the top of the support board, the base coat of a liquid resin diffusing at least in part into an upper edge layer of the support board and penetrating and coating a remaining area of the press skin at least in part, d) drying the base coat of the liquid resin based on melamine, e) applying a primer to the base coat of the liquid resin based on melamine, f) drying the primer, g) applying at least one water-based lacquer with dye pigments added for producing a decoration, h) drying the decoration, i) applying a seal of at least one melamine-based resin with wear resistant particles and cellulose fibers added, j) drying the seal, k) applying a base coat of a melamine-based liquid resin to a bottom of the support board, the base coat of a melamine-based liquid resin diffusing at least in part into a lower edge layer of the support board, l) drying the base coat of the melamine-based liquid resin, m) applying a contacting layer to the bottom of the support board, n) molding the laminar structure under action of pressure and temperature, o) dividing the support board into panels of a desired width and length, p) attaching connecting mechanisms and interlocking elements to opposing side edges for glueless joining and interlocking of several panels into a composite floor which has been laid floating.
