ABSTRACT:
A method for injecting a treating liquid into a wood or stone material. The liquid is injected in an initial pressure-applying/injecting step in which the wood or stone material is immersed at ambient temperature in a treating liquid under an initial liquid pressure of 1 to 10 kg/cm.sup.2, and maintained at this pressure for a period of time. Subsequently, the pressure is increased to a final pressure having a maximum value of 50 kg/cm.sup.2. Where wood is being treated, the pressure is raised in a plurality of steps of 5 to 10 kg/cm.sup.2 each, followed by a defined holding period. Where stone is being treated, the pressure is increased in a single step. Finally, the treated material is depressurized over a period of at least 20 minutes.
