Investigations were carried out of technical properties possessed by wood carvings forming the parts of adornments in towers of Royal Palace at Wilanów. The wood material of these carvings has been seriously destroyed as result of weather action (s.c. “w ea th e ring”) and also owing to development of three species of fungi, finally due to damages caused by insects which all the above factors considerably deteriorated their technical properties. Already the saturation of wood from which the carvtings were made with synthetic resin “Vinoflex MP-400” with a simultaneous application of negative pressure apparently improved its technical properties. Highly satisfactory results have been obtained for wood material damaged by weathering in superficial layers as w e ll as for that showing the medium degree of destruction by fungi. However, the carvings showing more serious damages, although a considerable degree of improvement as to their technical properties has been observed, differed substantially as to the lev e l compared with that of values characteristic for unaffected wood. In result of saturation with “Vinoflex MP-400” an essential reduction o f wood permeability and hygroscopicity has been achieved but both the improvement of its hardness and heightening of crushing strength was accompanied by an increase of specific weight. In several samples the above properties were nearing those characteristic for unaffected wood or even better.
