How long do corrugated plastic yard signs last outdoors?

Corrugated plastic yard signs printed with UV-cured inks typically last 6 to 12 months outdoors before you notice fading. The plastic outlives the print, so color is usually the limiting factor.

• Print life: about 6 to 12 months before noticeable fading with UV-cured inks.
• Material life: the corrugated plastic itself can survive much longer, so structural failure is rarely the limiting factor.
• Main factor: extended direct sun speeds up fading; kept indoors and out of UV light, the same signs can look sharp for several years.
• Reflective finish: a reflective coating resists fading better than a standard surface, stretching usable outdoor life.
• Longer-term option: for signs meant to last years outdoors, aluminum is the better pick.

To get the most life, keep signs out of constant afternoon sun where you can and store them indoors between uses.
