Abstract

Method of decreasing the formaldehyde emission of chip and fibre boards of emission class E1 which are veneered with refining layers, characterised in that, before veneering, the boards are treated in a manner known per se with aqueous solutions of urea and/or other ammonia-eliminating compounds, and in that the refining layers are subsequently applied in a manner known per se.
