Abstract

A method of reducing the emission of formaldehyde from formaldehyde laden layered products having at least 2 layers, at least one of which being a board or veneer, wherein prior to bonding the layers together, at least one side surface of said board or veneer is treated with a solution comprising an inorganic sulphur containing salt. The invention also relates to a board, a veneer and a flooring material obtainable by the method, to an aqueous solution comprising ammonium sulphite or bisulphite and urea for use in the method and to a process for preparation of the aqueous solution.
