Abstract

Description d'une méthode pour traiter le bois ayant subi un traitement de préservation qui fait en sorte que l'agent de préservation est protégé substantiellement contre le lessivage. Le traitement comprend le séchage du bois traité jusqu'à ce que la teneur en humidité du bois soit inférieure à un niveau capable de convenir à la diffusion de l'agent de préservation.
