The present invention relates to a method and to an apparatus for providing a wood surface (2) which as good anchorage for paint and/or glue and/or for arresting the formation of cracks. The wood is irradiated with pulsed light from a light source (3) of such strength and in such pulse numbers as to break covalent bonds in the material along the wood surface, at least so as to remove the damaged cell structure of the surface to a depth exposing the cell structure of the surface.
Appareil et procédé permettant d'obtenir une surface de bois (2) offrant un bon accrochage à la peinture et/ou à la colle et/ou s'opposant à la formation de fissures. Le bois est irradié par des impulsions lumineuses émanant d'une source lumineuse (3) présentant une intensité et selon un nombre d'impulsions tels que les liaisons covalentes sont rompues le long de la surface du bois, de sorte qu'au moins la structure cellulaire endommagée de la surface soit enlevée jusqu'à une profondeur à laquelle la structure cellulaire de la surface est dégagée.
