Maintaining wooden outdoor furniture in an urban setting is crucial for its longevity and appearance. The frequency for re-treatment or sealing primarily depends on the wood type, climate, and finish used. As a general rule, most wooden furniture requires re-sealing every 1 to 2 years. However, in harsh urban environments with more pollution, sun exposure, and seasonal changes, you may need to inspect and potentially re-treat it annually.
Start by checking the wood's water resistance. Sprinkle a few drops of water on the surface. If the water beads up, the seal is still effective. If it soaks in, it's time for a new coat. Proper preparation is key: clean the furniture thoroughly, allow it to dry completely, and sand lightly if needed before applying a fresh layer of a high-quality sealant, wood oil, or stain. Consistent maintenance not only preserves the wood's beauty but also prevents rot and splintering, ensuring your urban outdoor space remains stylish and functional for years to come.
