The invention relates to a method for drying coated and/or impregnated objects (5), especially of varnished painted wood. According to said method, a coating and/or impregnating agent applied on the surface of the respective object is dried by infrared radiation of the coated or impregnated object before the characteristic period for drying has expired. The characteristic period is determined by the time during which an absorption, that means a penetration of components of the coating and/or impregnating agent (22) into the object (5) takes place so that the quality of the coating or impregnation is impaired. Alternatively or additionally thereto, the characteristic period is determined by the fact that after expiration of said period the penetration of a solvent and/or diluent of the coating and/or impregnating agent (22) which solvent and/or diluent should be stripped and/or bound during drying has caused the fibers of the object (5) to stand up so that a secondary treatment of the surface is required or desirable.

L'invention concerne un procédé permettant de sécher des objets revêtus et/ou imprégnés (5), notamment de bois laqué. Un agent de revêtement et/ou d'imprégnation appliqué sur la surface de l'objet concerné est, avant l'écoulement d'un temps caractéristique, traité par exposition de la surface revêtue ou imprégnée aux rayons infrarouge. Ce temps caractéristique est déterminé par le temps pendant lequel se produit une absorption, c'est-à-dire la pénétration de constituants de l'agent de revêtement et/ou d'imprégnation (22) dans l'objet (5), de telle façon que la qualité du revêtement ou de l'imprégnation soit détériorée. En variante ou en plus, le temps caractéristique est déterminé de telle façon qu'à son terme, une pénétration d'un solvant et/ou d'un agent de dilution à expulser et/ou à lier lors du séchage du solvant et/ou de l'agent d'imprégnation (22) a entraîné un redressement des fibres de l'objet (5), de telle façon qu'un traitement ultérieur de la surface soit nécessaire ou souhaitable.
