The 30-Second Verdict
Sherwin-Williams Emerald and Duration lines dominate Florida contractor usage due to self-priming formulas, strong mildew resistance, and widespread retail availability. Benjamin Moore Aura and Regal lines produce richer color depth and are preferred by premium painters — but cost 20-30% more per gallon. For exterior Florida applications where UV fading and mildew are the primary concerns, SW Duration with a quality primer is the industry workhorse. For interior or color-critical projects, Benjamin Moore Aura is worth the premium.

Frequently Asked Questions
How often do you need to repaint a Florida home exterior?
Florida's intense UV and humidity degrade exterior paint faster than most US climates. Most FL homes need full repainting every 5-7 years vs 8-10 nationally. Using a quality primer and a 2-coat application of Duration or Aura Exterior extends intervals to 8-10 years. Dark colors fade fastest — lighter tones and lighter sheens hold up better.
Which paint brand resists mold and mildew best in Florida?
Sherwin-Williams Duration has the most established field record in Florida contractor use. Both Duration and Benjamin Moore Aura contain mildewcide additives. For south Florida and high-humidity coastal areas, always add a dedicated mold-resistant primer (Zinsser or Kilz) under exterior paint regardless of brand.
What sheen should I use for a Florida exterior?
Satin or low-lustre finishes are the Florida standard for exterior walls — easier to clean than flat, less reflective than semi-gloss. Trim should be semi-gloss for durability. Avoid flat exterior paint in Florida; it traps moisture and fails faster.
