Powder Coating vs. Spray Paint for Outdoor Furniture
Powder coating is far more durable than spray paint for outdoor furniture. Powder is applied electrostatically to bare, blasted metal and oven-cured into a hard shell that resists chipping, chlorine, salt air, and UV for roughly ten years or more. Spray paint is a thin surface film that typically chalks, chips, or peels within one or two Los Angeles summers.
How the two finishes differ
Spray paint dries. Powder coat cures. That single difference explains most of the performance gap: cured powder cross-links into a continuous shell bonded to the metal, while paint sits on top as a film that can lift wherever moisture finds an edge.
Powder coating also requires real preparation. Frames are media-blasted to bare metal and chemically pretreated, so there is no old rust or failing coating trapped under the new finish.
Cost and lifespan
Spray painting a chair frame is cheap up front and usually needs redoing every year or two, which costs more over a decade than doing it once properly.
Powder coating starts near $120 per chair frame with a two to three week turnaround, because blasting, coating, curing, and reassembly are separate stages. In Los Angeles conditions the finish commonly lasts ten years or longer.
When spray paint is acceptable
Touch-up on a low-value piece you plan to replace soon, or a small area where disassembly is impractical. For anything you intend to keep, powder coating is the finish that actually holds.
