Picking the right exterior paint for a Florida home isn't like picking a paint in Ohio. The Sunshine State gives your exterior the worst of every environmental stressor at once — intense UV, daily humidity swings, salt air on the coast, sudden heavy rain, and 90°F+ surface temperatures for half the year. Most consumer-grade and builder-grade exterior paints aren't engineered for that, and they fail within 2–4 years.
At Launch Painting Co., we've been painting Brevard County homes — Melbourne, Viera, Suntree, Indialantic, Satellite Beach, Palm Bay — for years. Here's what we've learned about what works, what doesn't, and what to specify if you want your exterior to last 10+ years.
Why Florida is hard on exterior paint
Three forces destroy exterior coatings in Florida:
- UV radiation. Florida sees roughly 30% more UV exposure than the national average. UV breaks down the resin binders in cheap paint, causing chalking, fading, and loss of film integrity.
- Humidity & thermal cycling. Coastal Brevard humidity averages 75%+ year-round. Walls heat up, cool down, and absorb/release moisture daily. Rigid paint cracks; only flexible 100% acrylic formulas survive long term.
- Salt air & wind-driven rain. Within a mile of the Atlantic, salt is constantly depositing on surfaces. It pulls moisture into the paint film and accelerates failure on metal, wood, and porous stucco.
What to look for in an exterior paint
1. 100% acrylic resin
This is non-negotiable. Vinyl-acrylic and lower-grade blends save the manufacturer money but lose flexibility and UV resistance fast. Look for "100% acrylic" on the data sheet, not just "acrylic."
2. High volume solids (35%+)
Volume solids is what's left on your wall after the paint dries. Higher solids = thicker, more durable film per coat. Builder-grade exterior is often 28–32%. Premium products like Sherwin-Williams Duration or Benjamin Moore Aura Exterior run 38–45%.
3. Mildewcide additives
Florida mildew is aggressive. Premium exterior products include in-can mildewcides that resist black streaks on north-facing and shaded walls — a constant problem in humid climates.
4. Elastomeric capability for stucco
Stucco moves. Hairline cracks open and close with thermal cycles. Elastomeric coatings stretch to bridge those cracks instead of splitting. Pure elastomerics are sometimes overkill (and trap moisture if misapplied), but elastomeric-capable acrylics like Duration or SuperPaint are the sweet spot for most Brevard homes.
Our recommendations by substrate
Stucco & masonry
Sherwin-Williams Duration Exterior or Benjamin Moore Aura Exterior. Both are 100% acrylic, high-solid, mildew-resistant, and rated for 10–15 years in Florida conditions when applied over properly-prepared and primed stucco.
Wood trim, fascia, soffits, doors
Sherwin-Williams Emerald Exterior or BM Aura Exterior Satin. For doors and trim that need a smoother flow, we often spec an acrylic-alkyd hybrid like SW Emerald Urethane Trim or BM Advance — they level like oil but don't yellow.
Metal (railings, shutters, garage doors)
Rust-inhibitive primer first (SW Pro Industrial Pro-Cryl or Rust-Oleum equivalent), then a 100% acrylic DTM (direct-to-metal) topcoat. Salt air kills bare and improperly-primed metal within a single season on the beaches.
What about cheaper "5-year" paints?
Manufacturer "warranty" years on cheap exterior paints are calculated under ideal conditions — a Pittsburgh climate, perfect prep, no UV extremes. In Florida, a "10-year" builder-grade product realistically lasts 3–4 years before it chalks, fades, or peels.
The math almost always favors the premium product. A repaint costs roughly the same in labor whether you buy $30 paint or $90 paint — but the $90 paint lasts 2–3× longer. You'll pay less per year owning the home.
Prep matters more than product
Even the best exterior paint fails over bad prep. Our standard prep on every Brevard County exterior:
- Pressure wash with mildew-kill solution and clean rinse.
- Scrape and sand all failing paint to a sound edge.
- Caulk all dynamic joints with paintable polyurethane sealant.
- Spot prime bare stucco with a masonry primer and bare wood with a stain-blocking primer.
- Two true coats — not one heavy coat called two.
Skip any of these steps and you're shaving years off the life of the system. See our complete process for more detail.
Bottom line
For a Brevard County exterior repaint that actually lasts, spec 100% acrylic Sherwin-Williams Duration or Benjamin Moore Aura on stucco, an acrylic-alkyd hybrid on trim, and a rust-inhibitive system on metal — applied over proper prep by a crew that knows Florida coatings.
