The frequency with which you need to treat or seal your wooden outdoor furniture depends on several factors, including the wood type, climate, and furniture exposure. Generally, most wooden furniture benefits from annual inspection and maintenance. Hardwoods like teak and cedar may only require treatment every 1-2 years, while softer woods like pine might need sealing every 6-12 months.
In harsh climates with intense sun or heavy rainfall, you may need to seal furniture more frequently – potentially every 6 months. Milder climates might extend the interval to 18-24 months for durable hardwoods. The best approach is to perform water tests: sprinkle water on the wood surface. If it beads up, the sealant is still effective. If it soaks in immediately, it's time for resealing.
Regular cleaning before resealing is crucial. Use a mild soap solution and soft brush to remove dirt and mildew. Allow the wood to dry completely before applying any sealant or treatment. For optimal protection, choose products specifically designed for outdoor wood, whether oil-based for a natural look or film-forming sealants for maximum water resistance. Consistent maintenance not only preserves your furniture's appearance but significantly extends its lifespan against weather elements.
