Sažetak
Wood exposed to the outdoors undergoes photooxidative degradation in the natural weathering process. UV light interacts with lignin to initiate discoloration and deterioration. The photodegradation of wood is a major drawback in the use of wood for outdoor applications. This problem can be minimised if the wood is coated with a fully opaque paint. Clear coating system have become popular due to thair ability to enhance the aesthetic properties of the wood. Most of them do not function effectively. In addition, many UV absorbers, quenchers, and hindered amine light stabilizers have also been used. The results of an investigation into the discoloration of a typical softwood ( fir wood , Abies alba Mill.) and tipical hardwood (oak wood, Quercus robur L.), both uncoated and coated with a clear film-forming water-based stain with various photostabilisers are discussed in this paper.
