The efficacy of various treatments for the protection of wood surfaces from weathering elements (ultraviolet radiation and water) was investigated by using the measurements of the changes in adhesion on fir and oak samples after their exposure to natural climatic conditions and after accelerated weathering. The most efficacious of the six UV-protective treatments proved to be the treatment of the wood surfaces with a semi-transparent stain, followed by treatments with a transparent wood stain containing two types of photostabilisers. The stabilisation of the wood surfaces by ferric nitrate did not improve the performance of the wood stain used.
