Maintaining the beauty and longevity of wooden urban outdoor furniture requires periodic sealing and re-treatment. The frequency depends on several key factors. Generally, most wooden furniture needs re-treatment every 1-3 years, though this can vary significantly.
The type of wood is crucial. Dense hardwoods like teak or cedar naturally resist moisture and may only need sealing every 2-3 years. Softer woods like pine require more frequent attention, often annually. Your local climate plays a major role. Furniture in rainy, humid climates or areas with harsh sun and extreme temperature swings will need more frequent re-treatment, potentially every year. Conversely, in mild, dry climates, you might extend the period to every 2-3 years.
Usage intensity matters greatly. A heavily used public park bench will show wear faster than a private balcony chair. Always inspect your furniture annually. Look for signs like water no longer beading on the surface, a fading or graying color, or a rough texture. These indicate it's time for maintenance. Proper preparation—cleaning and lightly sanding the surface—before applying a new coat of sealant is essential for optimal protection. Consistent care will ensure your outdoor furniture remains beautiful and functional for many seasons.
