Method for the production of a veneer

A method for the production of a veneer resistant to micro-organisms, insects and other harmful products, which is suitable for use in constructions intended for joinery, construction, packaging, and installation applications, the method comprising impregnating a wood veneer which is cut or sliced from a piece of timber, with a concentrated solution of an impregnation salt or other impregnation medium by applying the impregnation salt or other impregnation medium to the surface of the veneer while the veneer is still moist, under no mechanical pressure and before the ring pores thereof have become sealed, so that a controlled quantity of the solution of the impregnation salt or other impregnation medium is distributed in the veneer by chemical osmotic overpressure diffusion through the cell walls thereof, and drying the impregnated veneer by heating the veneer so that the ring pores of the cell walls thereof are sealed.
