Patent ID: 8512804

Claim:
A method for finishing an engineered wood board comprising a decor on at least a top and/or a bottom, comprising in order: (a) cleaning the top and bottom of the engineered wood board, (b) applying a first top resin layer, which contains corundum particles, to the top and a first bottom resin layer to the bottom of the engineered wood board, (c) drying the first top resin layer and the first bottom resin layer to a residual moisture content of 3% to 6% by weight, (d) applying a second top resin layer, which contains cellulose, to the top and a second bottom resin layer to the bottom of the engineered wood board, (e) drying the second top resin layer and the second bottom resin layer to a residual moisture content of 3% to 6% by weight, (f) applying an at least third top resin layer, which contains glass particles, to the top and an at least third bottom resin layer to the bottom of the engineered wood board, (g) drying the third top resin layer and the third bottom resin layer to a residual moisture content of 3% to 6% by weight, and (h) pressing the multilayer structure under action of pressure and heat; and where the composition of the first, second, and third top resin layers are different.
