The 30-Second Verdict
Both are premium paints, but Sherwin-Williams Duration and Emerald lines outperform Behr in independent tests for Florida-specific threats: UV fade, mildew, and salt-air film degradation. Behr costs 20–30% less at Home Depot and performs well for DIY projects. For professional exterior painting in Florida, most contractors specify Sherwin-Williams.

Frequently Asked Questions
How often does exterior paint need to be repainted in Florida?
Florida's intense UV, heavy rain, and humidity mean exterior paint typically lasts 5–8 years vs 10+ years in cooler climates. Using a premium product like Duration or Marquee with proper surface prep can push that to 8–10 years.
Why do Florida painters prefer Sherwin-Williams?
Professional painters cite better spray application properties, more consistent color batches, and superior mildew resistance in field tests. SW's 200+ Florida store locations also make mid-job restocking easy. Many contractors offer manufacturer warranties only when using SW products.
Does paint color affect how long it lasts in Florida?
Yes — dark colors absorb heat and tend to fade and crack faster in Florida's UV. Light to medium colors (LRV 55+) last measurably longer on Florida exteriors. If you choose a dark accent color, use the highest-grade product available and plan for more frequent touch-ups.
