ABSTRACT:
An improved method for the preservation of hardwood by treatment thereof with a preservation solution is disclosed. The wood is treated with a preservative solution which is not readily fixed and is then kept in an undried condition for a period of time sufficient to allow the preservative solution to penetrate the wood and diffuse through the cell walls of the wood without fixation thereof. The wood is then dried so as to fix the preservative. Enhanced periods of preservation effectiveness are thus obtained.
