The demand for wood content continues to grow as a result of an increasingly growing population and urbanisation phenomena. It is already well predicted that natural forest resources are likely to be unable to meet demand in the near future if consumption continues at this pace. Therefore, the conservation of forest resources, which have been heavily destroyed for the supply of wood as raw materials needed by the forest products industry, has been under extreme pressure. Continuous wetting and drying cycles result in cracking and deterioration of wood surfaces under outdoor atmospheric conditions, temperature, humidity, sunlight and UV radiation. However, with physicochemical reactions, changes in wood content caused by atmospheric conditions may be studied. It is unavoidable that both the aesthetic and natural characteristics of wood shift as a result of these dynamic phases. In order to make efficient use of this valuable material, it is important to know the physical, chemical and biological properties of the wood material and to use it for that purpose. However, certain approaches must be used to minimise the negative factors, to boost the areas of use and to make them immune to atmospheric factors in order to prolong service life.
