Rezumat: Consolidation of old wooden objects by cold immersion into consolidation polymer solutions is one fundamental treatment in the conservation of wooden cultural objects. Its main purpose is to ensure structural integrity and thus the preservation of object authenticity. The efficiency of a consolidation treatment is mainly given by the quantity and distribution of the consolidation product which penetrates into wood. The present paper presents an experimental study upon the weight percentage gain and distribution of Paraloid B 72 consolidant into the structure of poplar wood. The consolidants used were prepared at a concentration of 10% in two different solvents, toluene and a mixture of ethanol and acetone 1:1. The consolidation products were applied on sound poplar samples (10x10x15) mm by two different cold immersion treatments, several times of exposure being applied. The distribution of the consolidant inside the wood structure as well as its uptake was investigated by means of Scanning Electron Microscopy. The aim of this research was to establish the optimum recipe considering the two viewpoints. This represents the first stage within a wider research which envisages the addition of nano-insertions into the present consolidant Paraloid B72 in order to increase several properties of the consolidant material: fire retardancy, resistance to biological attack, mechanical strength.
