How do you design outdoor benches to be resistant to damage from power washing?

Designing outdoor benches to resist power washing damage requires careful material selection and construction techniques. Opt for durable, non-porous materials like powder-coated metal, marine-grade polymer, or dense hardwoods like teak. Ensure all joints are welded or sealed to prevent water infiltration. Apply UV-resistant, waterproof coatings to protect surfaces from high-pressure cleaning. Elevate bench legs slightly to avoid standing water and use corrosion-resistant fasteners. Sloped seating surfaces and drainage holes help prevent water accumulation, extending the bench's lifespan under frequent power washing.
