Keeping the screws on your metal outdoor benches rust-free is crucial for both aesthetics and structural integrity. Here are practical, effective strategies to protect them.
First, start with the right hardware. Always choose screws specifically designed for outdoor use. Stainless steel screws (especially 304 or 316 grade) offer excellent corrosion resistance. Galvanized screws are coated with a protective layer of zinc, providing a strong defense against moisture. For maximum protection, consider coated screws like those with a polymer or epoxy finish, which add an extra barrier.
Before installation, apply a protective coating. Use a clear rust-inhibiting spray or brush-on sealant designed for metal. For existing benches, remove any surface rust with a wire brush, then apply a metal primer followed by a matching outdoor-rated paint or clear coat. This seals the screw heads and the surrounding metal.
Regular maintenance is key. Wipe down your benches periodically to remove dirt, pollen, and moisture that can trap water against the metal. Inspect screws annually for early signs of rust. If you spot minor corrosion, address it immediately by cleaning and touching up the protective coating.
Consider the bench's placement. If possible, position it in a covered area or use a waterproof bench cover during harsh weather or off-seasons to limit prolonged exposure to rain and snow.
By selecting the correct screws, applying a protective barrier, and performing simple routine checks, you can significantly extend the life and beauty of your metal outdoor furniture, keeping those screws shiny and secure for years to come.
