Teak wood is prized for its beauty and functionality as well as its durability. All-natural teak wood is naturally weather and waterproof due to the abundance of natural oils. These same oils protect the wood from mold, mildew, and termite infestation. All of these features make teak wood the ideal material for spas, baths, poolside, and for patio furniture. Natural finish requires cleaning and sealing twice per year.
