Abstract

A method for forming of a building panel with a surface including a thermosetting resin such that tension created during curing of the surface is reduced or eliminated. Method for producing a panel with a wood based core and a surface layer including a thermosetting resin wherein the method including: curing and connecting the surface layer to the core while applying heat and pressure in a first main pressing step, thus raising a temperature of the surface layer above an initial temperature; applying a bending force on the panel after the first main pressing step to bend the panel such that an uppermost surface of the panel is convex an a lowermost surface of the panel is concave while the panel is still above the initial temperature; and releasing the bending force such that the panel springs back to an essentially flat shape.
