The invention relates to a process for treating old wood artifacts in order to stop insecto-fungal attack, to be applied in workshops for preservation-restoration of art works and antique furniture. According to the invention, the process consists of the following succsessive stages: sanitizing, cleaning and consolidating the surfaces to be treated, using a solid dispersion consisting of wax : paraffin or colophony : teak wood crumbs in a gravimetric ratio of 5.0:3.5:1.5, in fluid state, at a temperature of 64…66°C, by brushing in several layers, after which teak wood veneer sheets of 1.0…1.5 mm are applied by lining in one or two layers, with polymeric adhesive films of acrylic or collagen type and then, on the veneer-lined surfaces, cellulosic or urea-formaldehyde transparent films are applied, and possibly dispersions of acrylic copolymer and fine crumb teak wood in a ratio of 1:1 in dilutant, at three concentration levels, in order to provide a final thickness of the applied layer of 200 μm, at the most.
