It is also a fine furniture wood, Teak contains natural oils that can make it difficult to finish. The oils prevent surface coatings from adhering. The best finish for teak is a penetrating oil finish. Teak can be finished with other products if the wood is carefully cleaned with solvent to remove the natural oils, but this is not recommended for beginners. If some oil remains, the finish can crack and peel later.
Walnut is one of the easiest woods to finish.
It has a hard surface, and beautiful color and grain. A clear penetrating oil finish is often the finish of choice for walnut. The natural color of the wood is so desirable that many times other woods are stained in an attempt to duplicate the color that is achieved by simply applying a clear finish to walnut. A final buffing with wax can produce a higher gloss. Stain can be used to even out color variations.
