Not every exterior paint performs the same on every surface. Here's what actually holds up on Florida stucco, Hardie board, wood siding, and brick.
For most Northeast Florida homes: 100% acrylic exterior paint works well on Hardie board and wood, elastomeric or high-build acrylic is better for cracking stucco, and masonry-specific acrylic is needed for brick and block. Sherwin-Williams SuperPaint, Duration, and Emerald, along with Benjamin Moore Aura and Regal Select, are the product lines we reach for most in this climate.
Every exterior surface moves, absorbs moisture, and expands/contracts differently. Stucco is porous and prone to hairline cracking. Wood swells and shrinks with humidity. Hardie board is dimensionally stable but has butt-joint seams. Brick and block are extremely porous and alkaline. A paint film built to flex over cracking stucco can be overkill (and more expensive than needed) on stable Hardie board.
Stucco is the dominant siding in newer Nocatee, Julington Creek, and World Golf Village developments, and it's also the substrate most prone to hairline cracking in Florida's heat cycles.
Elastomeric coatings cost more per gallon and require correct application thickness (they're typically applied thicker than standard paint), but on cracking stucco they buy years of extra life.
Hardie board is common across newer construction from Fleming Island to Middleburg. It's dimensionally stable and holds paint better than wood, so a standard premium 100% acrylic exterior paint performs excellently here without needing an elastomeric upgrade.
Original wood siding and trim on older homes in Riverside, Avondale, and historic St. Augustine needs paint that can handle constant expansion and contraction as humidity swings. Bare or previously bare wood should get an oil-based or stain-blocking alkyd primer first, then two coats of a flexible 100% acrylic topcoat.
Brick ranches are common across Orange Park and Middleburg. Brick is highly porous and alkaline, especially if it's never been painted, and needs a masonry-specific primer to seal the surface and prevent efflorescence (the white mineral staining that pushes through paint from moisture).
Satin is the standard sheen for most Florida exterior bodies — it hides minor surface imperfections better than gloss while still being washable. Trim typically goes semi-gloss for contrast and easier cleaning. Full gloss on a whole house body shows every stucco imperfection and isn't common outside of specific architectural styles.
Homes near the Intracoastal or ocean in Ponte Vedra Beach, Atlantic Beach, and Fernandina Beach see accelerated paint breakdown from salt exposure. In these zones we lean toward elastomeric coatings on stucco even without existing cracking, and we push for annual gentle rinsing to keep salt residue from sitting on the paint film between repaints.
"Paint and primer in one" products work fine as a topcoat over an already-primed, previously painted surface in good condition. They are not a substitute for a real bonding or stain-blocking primer over bare stucco, bare wood, or raw brick — skipping true primer on bare substrate is one of the most common causes of early peeling we get called out to fix.
Regardless of substrate or paint line, two full coats of exterior acrylic is the standard for a durable finish in this climate. A single coat, even of premium paint, leaves a thinner film that breaks down faster under constant Florida UV exposure.

Only when the stucco already has hairline cracking. On stucco in good condition, a high-build 100% acrylic works well and costs less. Elastomeric shines specifically at bridging small existing cracks.
You can use the same 100% acrylic topcoat product, but wood typically needs a stain-blocking or oil-based primer first, while factory-primed Hardie board usually just needs caulking at the seams before topcoats.
Raw brick is highly porous and alkaline, and without a masonry primer or block filler, moisture can push through the paint film and cause efflorescence, a white mineral staining. Masonry primer seals the surface and gives the topcoat something stable to bond to.
Satin is the standard for exterior bodies here because it hides surface imperfections while staying washable. Trim is usually painted semi-gloss for contrast and easier cleaning.
