Abstract

The invention relates to a method for the treatment of surfaces of wood or woodbase materials with surface treatment compositions, and the timbers or woodbase materials thus treated by impregnating with a curable aqueous composition of α) low molecular weight compounds V which have at least two N-bonded groups and/or β) precondensates of the compound V and/or γ) reaction products or mixtures of the compound V with at least one alcohol which is C1-C6-alkanols, C2-C6-polyols or oligoalkylene glycols; treating that impregnated material at elevated temperature and) treating at least one surface of the wood or woodbase material to be treated with a surface treatment composition.
