Maintaining wooden outdoor furniture in a city environment requires consistent care due to unique urban stressors. Generally, you should apply a protective sealant or treatment at least once a year. However, in dense urban areas with high pollution, fluctuating temperatures, and exposure to de-icing salts or soot, inspecting and potentially treating your furniture every 6 to 9 months is advisable.
The frequency depends on the wood type, finish quality, and specific exposure. Hardwoods like teak may need less frequent care, while softwoods like pine require more. Start by cleaning furniture thoroughly. Check for signs of wear like graying, cracking, or water absorption. If water no longer beads on the surface, it's time for treatment.
Use a high-quality sealant, oil, or stain designed for exterior wood. Apply during mild, dry weather for best absorption. Regular cleaning between treatments—wiping down surfaces and removing debris—will significantly extend the protection period. This proactive approach combats city grime, moisture, and UV rays, preserving your furniture's beauty and longevity.
