Abstract

A method of manufacturing a building panel, including mixing wood fibre particles and a binder to form a first mix, applying the first mix, while the first mix is in powder form, on a core for forming a sub layer on the core, applying a surface layer on the sub layer, wherein the surface layer comprises a second mix of wood fibre particles and a binder, pressing the core, the surface layer, and the sub layer, under increased pressure and temperature, and forming them into a building panel. A building panel formed by the method.
