    Abstract: A wood article is surface-treated by first pretreating the same with a condensable or polymerizable hydrophilic liquid monomer, substantially free of any solvent, in order to cause the wood to swell and/or to dissolve constituents of the wood. The resulting pretreated wood article is then directly treated with an impregnating agent, that reacts with such monomer, to form a condensate or polymerizate with the monomer. Finally, the impregnated condensate or polymerizate thus formed in the resulting treated wood is hardened.

    Abstract: AQUEOUS WETTING SOLUTIONS COMPRISE STABLE COLLOIDS, THE SOLID PHASE OF WHICH IS A HYDROUS OXIDE OF ONE OR MORE SELECTED ELEMENTS. THE SOLID, PARTICULATE PHASE OF THE COLLOID IS PRODUCED BY A CONTROLLED HYDROLYSIS AND NUCLEATION REACTION WHICH CONTINUES UNTIL SOLID PHASE PARTICLES HAVING APPROPRIATE SIZE AND SURFACE CHEMISTRY RESULT. APPLICATION OF THE WETTING SOLUTIONS TO ANY KNOWN NONWETTABLE SURFACE RENDERS SUCH SURFACE WETTABLE, VIA DEPOSITION OF THE PARTICLES OF THE SOLID PHASE ONTO THE SURFACES BY SHORT ORDER FORCES. THE RENDERING OF THE SURFACES WETTABLE IS ACCOMPLISHED WITHOUT EFFECTING A PHYSICAL OR CHEMICAL CHANGE OF THE SURFACE.
