External wooden constructions have their own place in building industry from ages. The external wooden construction easily degrade due to UV radiation, atmospheric conditions and biological aggressors. We are trying to eliminate the negative impact of degradation factors by wood protection. Types of wood protection include all measures which would protect wood from influences of fungi, insects, weather (temperature, humidity, wind,), natural calamities (fire, flood) and they can be divided into chemical protection and radiation protection. In our paper we will discuss a new solution based on titanium dioxide (TiO 2 ). Titanium dioxide was proved to be an efficient UV absorber and moreover, in its crystalline form, it is able to destroy biological aggressors too. Nowadays, there is no information about the interactions between wooden surface and non-photoactive or photoactive form of TiO 2 . TiO 2 exists in many morphological forms. The planar particles were chosen for purpose of the experiment. They can be prepared as non-photoactive and photoactive. This material was applied on wooden surface in the form of dispersion and created a transparent layer.
