<p>A method of preventing re-swelling of a compressed wooden blank, comprising the steps of: a) providing a blank consisting of compressed wood; b) exposing the blank to a reduced gas pressure of at most 0.5 atm; c) submerging the blank in a volume-stabilising composition containing i) a hydrophobic base component and possibly ii) an additive which is compatible with the hydrophobic base component and which includes one or more hydrophilic groups chosen from carboxyl-, hydroxy- and amino groups; d) exposing the blank to a higher pressure than in step b) over a predetermined period of time whilst keeping the blank submerged in said volume-stabilising composition; and e) removing the blank from the composition, any part of the composition present on the surfaces of the blank being sucked into said blank therewith leaving the surfaces of said blank dry, wherein step b) and step c) are carried out at one and the same time during at least a part of the process. A composition to be used in this process. The use of this composition in a method of preventing re-swelling of a compressed wooden blank.</p> |
