How Long Does Paint Last? Shelf Life, Wall Life, and When to Replace

Paint is more durable than you think — both in the can and on the wall. Here's how long every form of paint actually lasts.

Unopened paint shelf life

• Latex (water-based): 10 years stored properly
• Oil-based: 15+ years
• Chalk paint: 1–5 years (binders break down faster)
• Acrylic: 10 years

Opened paint shelf life

• Latex, resealed properly: 2–4 years
• Oil-based, resealed: 2–7 years
• If frozen: usually ruined — check before using

Paint life on walls

• Interior, low-traffic adult bedroom: 8–12 years
• Interior, living room/hallway: 5–8 years
• Interior, high-traffic (kids' rooms, kitchen): 3–5 years
• Exterior wood siding: 5–10 years
• Exterior stucco: 10–15 years
• Exterior fiber cement: 15–20 years

Signs paint has gone bad

• Sour, putrid smell when opened
• Lumps that won't stir out
• Layered separation that won't recombine
• Skin on top that won't break up
