Finishes are applied to wood for two main reasons: appearance and protection. The porous nature of wood means that it will soak anything that gets splashed on top of it— be it dirt, water, oil or other chemicals. Finishes ensure that the wood surface is sealed so gunk and other unwanted stuff are kept off. This helps protect the piece from damage for years to come.

​Also, wood has grains and knots and the application of the right finish allows these characteristics to be highlighted, further enhancing the natural beauty of the surface. Finishes like stains will help bring this out, which is generally then finished with a clear coat to better protect the surface.
