Metal outdoor furniture is a durable and stylish addition to any patio or garden. However, the bolts and screws that hold it together are often the first components to succumb to rust, which can weaken the structure and detract from its appearance. Preventing this corrosion is key to extending the life of your furniture. Here’s a practical guide on how to keep those fasteners rust-free.
The most effective strategy is to start with the right materials. Whenever possible, choose screws and bolts made from rust-resistant materials. Stainless steel, particularly grades 304 or 316, is an excellent choice for its inherent resistance to corrosion. Galvanized steel is another great option, as it has a protective zinc coating that acts as a barrier against moisture.
If you are working with existing hardware or standard steel fasteners, applying a protective coating is your best defense. You can use a clear acrylic spray sealant or a specialized rust-inhibiting paint. For a more robust solution, consider a fluid film or a light machine oil, which can be reapplied periodically. Before applying any coating, ensure the bolts and screws are completely clean and dry. Remove any existing rust with a wire brush or sandpaper.
Regular maintenance is crucial for rust prevention. Keep your furniture clean by wiping it down regularly to remove dirt, pollen, and moisture. During the wet season or winter, if feasible, store your furniture in a dry place like a garage or shed. If storage isn't an option, use a waterproof cover, but ensure it is breathable to prevent moisture from being trapped underneath, which can accelerate rusting.
For an added layer of protection, inspect the fasteners annually. Tighten any that have loosened and check for early signs of rust. If you spot any, address it immediately by cleaning the area and applying a touch-up coat of your chosen sealant. By selecting the right hardware, applying protective coatings, and performing simple, consistent maintenance, you can effectively prevent rust and ensure your metal outdoor furniture remains sturdy and beautiful for many years.
