The frequency for applying a protective sealant to your wooden outdoor furniture typically ranges from every 1 to 3 years. However, this isn't a one-size-fits-all answer, as several factors significantly influence the exact timeline.
The primary determinant is your local climate. Furniture exposed to harsh, direct sunlight, heavy rainfall, snow, or high humidity will require more frequent sealing – potentially every year. In contrast, furniture in milder, covered, or shaded areas might maintain its protection for 2-3 years.
The type of wood also matters. Dense, naturally resilient woods like teak or cedar may last longer between applications, while more porous woods like pine need sealing more often. The quality of the sealant itself is another crucial factor; a high-quality, UV-resistant product will offer longer-lasting protection than a cheaper alternative.
Instead of relying on a strict calendar, inspect your furniture annually. Look for signs that resealing is necessary: the wood appears gray or faded, water no longer beads up on the surface but soaks in, or the finish feels rough and dry. A simple water test—sprinkling water on the wood—is an excellent way to check. If it beads up, the sealant is still effective. If it soaks in, it's time for a new coat.
Proper preparation before resealing is essential for the best results. Always clean the furniture thoroughly and allow it to dry completely before applying a fresh coat of sealant. This ensures optimal adhesion and maximum protection for your investment.
