Teak wood is a premier choice for urban outdoor furniture due to its natural durability and resistance to the elements. A common question among owners is how frequently this furniture needs to be sealed or treated to maintain its appearance and longevity. The answer isn't one-size-fits-all, as the frequency depends on several key factors.
For teak furniture that you wish to maintain in its original golden-brown hue, applying a high-quality teak sealer is essential. Generally, you should plan to reseal teak furniture once or twice a year. However, this schedule can vary significantly. Furniture exposed to intense, direct sunlight, heavy rainfall, or extreme seasonal changes will require more frequent sealing—potentially every 6 to 9 months. In contrast, furniture placed in a more sheltered location, like a covered balcony, may only need treatment every 12 to 18 months.
The age and current condition of the furniture also play a role. New teak has a high concentration of natural oils. You can allow it to weather naturally for a few months before applying the first sealant. Older, greyed teak that you want to restore to its golden color will need a thorough cleaning before sealing, and the initial sealant may not last as long as on well-maintained wood.
If you prefer the silvery-grey patina that teak naturally develops over time, you can forgo sealing altogether. This patina is a sign of the wood's natural aging process and does not harm its structural integrity. In this case, maintenance is minimal, requiring only occasional cleaning with a mild soap solution to remove dirt and mildew.
Ultimately, the best approach is to inspect your furniture annually. If water stops beading up on the surface, it's a clear sign that the protective sealant has worn off and it's time for a new application. By understanding these factors, you can create a personalized care schedule that keeps your teak furniture looking beautiful for years to come.
