Teak garden benches are prized for their natural durability and beauty, but a common question among owners is: how often should I re-oil or seal them? The honest answer might surprise you: for pure longevity, never is often best. Mature, high-quality teak contains natural oils that protect it from within. Applying commercial oils or sealants can actually trap moisture, promote mildew, and lead to a cycle of constant maintenance.
If your goal is to maintain the classic golden-brown hue, you may choose to apply a teak sealer (not an oil) annually. Sealers are designed to slow the weathering process to silver-gray. For this purpose, inspect and likely reapply once every 12 to 18 months, depending on your local sun and rain exposure.
If you prefer the rich, dark look provided by teak oil, understand that this requires the highest maintenance. Teak oil penetrates poorly and wears off quickly, meaning you might need to re-oil your bench 2 to 3 times per year during peak seasons to maintain a consistent color. It can also encourage surface cracking.
Instead of frequent sealing or oiling, we recommend simple, regular care: clean your bench with a soft brush and mild soapy water once or twice a year to remove dirt and organic matter. This allows the wood to weather gracefully to a elegant silver-gray patina, which is its most stable and low-maintenance state. Ultimately, the frequency depends entirely on your desired aesthetic. For a natural, care-free bench, let it age. For a specific color, be prepared for a recurring commitment.
