An investigation into the protection of wood from UV-radiation and water

The efficacy of various treatments for the protection of wood surface from ultraviolet (UV) 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 efficious of the six UV-protective treatments proved to be the treatment of the wood surface with the semi-transparent stain, followed by treatments with the transparent wood stain containing two types of photostabilizers. The stabilisation of the wood surface by chromium trioxide and ferric nitrate did not yield results which were expected according to the previous research.
