Zusammenfassung:	A method for treating a plywood board (100). The method comprises providing a plywood board (100) comprising a first (110) and a second wood veneer layer (120), adhesive (190) between the wood veneer layers (110, 120, 130, 140, 150), a first surface (112) whose normal (N) is parallel to the thickness (tp) of the plywood board (100), and a second surface (122) opposite to the first surface (112); and hydrofobizing agent (310). The first surface (112) of the plywood board (100) is or has been sanded. The method comprises applying treatment agent (300) comprising hydrofobizing agent (310) onto at least the first surface (112) of the plywood board (100), wherein the treatment agent (300) is a dispersion or an emulsion of the hydrofobizing agent (310) and hydrofobization agent (310) is a wood based substance. A plywood board (100) that has been treated by the method.
