Abstract: A hardened wooden flooring product is produced by impregnating wooden flooring blanks with a hardener while the wooden flooring blanks are in a bundle, wherein the bundled hardened wooden flooring blanks have improved separation characteristics following completion of the impregnation treatment. The flooring product is made by assembling a plurality of wooden flooring product blanks into a bundle of blanks in surface-to-surface contact with each other and enclosing the wooden flooring blanks in a pressure vessel. The pressure vessel is evacuated and an effective quantity of a hardening composition for being impregnated into the wooden flooring blanks is introduced into the pressure vessel. An effective quantity of a polyethylene glycol composition is introduced into the pressure vessel. The wooden flooring blanks are soaked in the hardening composition and the polyethylene glycol composition for a predetermined period of time.
