Teak Facts: Teak, a traditional hardwood, is perfect for garden furniture. Combining strength with a high proportion of natural oils, teak is ideal for creating the smoothest of finishes with durability lasting in excess of 25 Years. When left untreated, teak mellows to an attractive silver grey colour. You may prefer to retain the rich golden brown colour of the wood by using treatment products. A regular clean will enhance the natural beauty of the timber.
