A method for preparing a treated cellulosic material comprising:
- (a) providing a cellulosic material;
- (b) a first treatment protocol comprising impregnating the cellulosic material with an aqueous dispersion comprising a polymer, the polymer comprising an olefin-carboxylic acid copolymer wherein at least a portion of the carboxylic acid groups of the copolymer are neutralized;
- (c) a second treatment protocol comprising impregnating the cellulosic material with a modifying agent comprising N-methyl N-hexylamine, N,N-diethyl n-hexylamine, n-octylamine, n-decylamine n-dodecylamine, N-methyl cyclohexylamine, N,N,-diethyl cyclohexylamine, dicyclohexylamine, benzylamine, cocoamine, oleylamine, stearylamine, an N,N-dimethyl substituted fatty amine, phenethylamine or tallowamine, the modifying agent comprising a hydrophobic amino.
