Living near the ocean is a dream, but the salty sea air is a nightmare for metal furniture. That constant, moist salt spray accelerates rust and corrosion dramatically. Don't worry—your metal benches aren't doomed! With the right proactive steps, you can enjoy them for years. Here’s your essential guide to preventing rust on coastal benches.
First, start with the right material. If you're purchasing new benches, opt for inherently corrosion-resistant metals. Aluminum, stainless steel (especially grade 304 or 316), and galvanized steel are top choices. They have protective layers or properties that fiercely resist salt attack.
For existing benches or any metal, a high-quality protective coating is your best friend. Thoroughly clean and sand the surface to remove any existing rust. Then, apply a specialized metal primer followed by a paint formulated for marine or direct-to-metal (DTM) use. For a clear finish, marine-grade spar urethane or enamel creates a durable, waterproof barrier. Reapply this coating every 1-2 years, as it will degrade.
Routine maintenance is non-negotiable. Rinse your benches with fresh water weekly to wash off salt deposits. Every month, give them a gentle wash with a mild soap and water solution, then dry thoroughly with a soft cloth. Immediately address any chips or scratches in the paint by touching them up to prevent moisture from reaching the bare metal.
Consider physical protection. Using fitted, breathable covers during storms or the off-season shields benches from direct salt spray and rain. Also, ensure benches are placed on a level surface where water doesn’t pool around the legs, and try to position them slightly away from the direct shoreline spray if possible.
Finally, inspect regularly. Make a habit of checking for early signs of rust, bubbles in the paint, or pitting. Catching corrosion early makes it easy to sand, treat with a rust converter, and repaint a small area, stopping a major problem before it starts. With consistent care, your metal benches will remain beautiful and functional, facing the sea breeze with confidence.
