There's no single timeline that fits every park bench. The frequency for repainting or refinishing depends heavily on several key factors. For painted metal or wooden benches, a thorough inspection every 1-3 years is wise. Refinishing—sanding and re-applying a stain or sealant—for wooden benches is typically needed every 2-4 years. However, benches in harsh coastal climates or under intense, direct sun may require attention annually. Conversely, a bench in a sheltered, temperate location might go 5 years or more.
Watch for clear signs it's time for work: flaking or faded paint on metal, or wood that looks gray, feels rough, or shows small cracks. Regular cleaning and immediate touch-ups on minor scratches can dramatically extend the period between major projects. Ultimately, proactive care based on your bench's specific environment and use is the best strategy for preserving its function and charm for years to come.
