The Graying of Teak
When left outdoors teak furniture will naturally weather to a silver gray color. You will begin to notice the “graying” after a few months, depending on the amount of sun and rain your furniture is exposed to. Total weathering usually takes about 6-8 months. During the weathering process a slight “checking” or roughening of the grain may occur in spots. You may even notice a few small cracks. Checking is not a structural defect, but a perfectly natural process, as the wood expands and contracts, adjusting to the elements. Water spots or other discoloration may also occur during the weathering process. These will eventually even out, and the furniture will take on a uniform silver-gray color
