Over time, yes, most park benches—especially those made of wood—do benefit significantly from special treatments and sealants. This maintenance is crucial for preserving their structural integrity, appearance, and longevity against constant exposure to sun, rain, and temperature fluctuations.
For wooden benches, a high-quality exterior-grade sealant, such as a penetrating oil seal or a UV-protective spar urethane, is highly recommended. This treatment should be applied every one to two years, or whenever the wood begins to look dry and gray. The process involves cleaning the bench thoroughly, allowing it to dry completely, and then applying the sealant evenly to form a protective barrier against moisture and UV damage.
Metal benches often require different care, primarily focused on preventing rust. Touch-up paint for powder-coated surfaces or a clear protective wax for ornamental iron can help seal small scratches and prevent corrosion. For concrete or composite material benches, a specialized concrete sealer or composite cleaner can protect against staining and moisture absorption.
Regular inspection is key. Check for signs of wear, splintering wood, or rust spots annually. A simple, consistent maintenance routine involving cleaning, inspection, and timely reapplication of the appropriate protective product will greatly extend the life of your park benches, keeping them safe and beautiful for years to come.
