The ideal treatment frequency for wooden outdoor furniture depends on several factors, including wood type, climate, and the specific protective product used. As a general rule, most wooden furniture should be sealed or oiled at least once per year. Hardwoods like teak or acacia may only require treatment every one to two years, while softer woods like pine might need attention every six to twelve months.
In harsh climates with intense sun, heavy rain, or significant seasonal changes, you may need to treat your furniture more frequently—potentially every six months. Conversely, in milder climates with furniture stored or covered during winter, an annual treatment may suffice.
The best indicator is the wood itself. Perform a simple water test: sprinkle a few drops of water on the surface. If the water beads up, the protective coating is still effective. If the water soaks in and darkens the wood, it's time for a new treatment.
Before applying any treatment, always clean the furniture thoroughly and allow it to dry completely. Use a product specifically designed for outdoor wood, such as a UV-inhibiting sealant, penetrating oil, or outdoor-rated wood stain. Consistent, timely treatment will protect your investment from moisture damage, UV fading, and wood rot, ensuring your outdoor furniture remains beautiful and functional for many seasons.
