Drive south out of downtown Stuart on Federal Highway and the housing stock changes underneath you. Around Cove Road the neighborhoods stop being wood-framed and start being block: Rocky Point, the villa and condominium clusters of Miles Grant Country Club along its southern edge just north of Cove Road, the working waterfront around Manatee Pocket in Port Salerno, and the inland gated golf communities — Willoughby, reached off Willoughby Boulevard north of Salerno Road, and Summerfield, just south of Cove Road and west of Federal Highway. Nearly all of it is CBS block with stucco, and nearly all of it has been painted before. Repeatedly.
That last part is the whole story of an exterior repaint in the 34997 zip code, and it is why this post sits separately from our Treasure Coast city guide, which covers downtown Stuart’s original wood trim, Sewall’s Point, and Rio. Those are prep problems about wood. South county is a prep problem about coating history — what is already on the wall, whether it is still stuck, and what is pushing it off from behind.
Three coatings deep, often more
Miles Grant’s golf club dates to 1972, and most of the homes, villas and age-qualified condominiums around it went up between 1973 and 1979. Port Salerno’s residential core is older still — it has been an active fishing port since the 1920s. Do the arithmetic on a home built in 1974 repainted on a reasonable seven-to-ten-year cycle, and a fair estimate is five or more coats on that wall today, laid down by different crews across five decades, over different primers, in whatever products were current at the time.
Those layers are not one film. They are a stack, and a stack fails at its weakest interface. The call we get most often in south Stuart is not paint that wore out — it is new paint that peeled off in sheets within two seasons, because a good product went over a layer three coats down that had already let go. The topcoat did nothing wrong. It was bonded to something that was not bonded to anything.
So the first hour of a repaint here is not about color. It is about finding out what we are standing on.
The adhesion test that decides the scope
The field method takes minutes per elevation. We cut an X through the coating down to the substrate, press a strip of tape firmly over the cut, pull it back at a sharp angle, and read what came away on a 0–5 scale. That is the X-cut procedure from ASTM D3359 — written for coatings on metal, but still the most practical read available on a painted masonry wall, and far better than guessing. We pair it with a chalk check, rubbing a dark cloth across the surface the way ASTM D4214 rates chalking, because a wall can be well bonded and still refuse to hold new paint if the old film has powdered.
Three outcomes, three different jobs:
- Clean pull, light chalk. The stack is sound. We soft wash, repair cracks and sealant joints, and go over it with a conditioner that binds residual chalk before topcoating. Sherwin-Williams Loxon Conditioner is built for this case — it bonds light chalk and dusting concrete and is meant for surfaces where the existing topcoat has deteriorated over time.
- Coating lifts off an older layer. Intercoat failure. Every square foot that lifts has to come off, and the edges feathered so the transition does not telegraph through the finish. This is the line item that separates an honest south Stuart quote from a cheap one.
- Coating lifts off bare block or stucco. Now we look for the reason, and in this zip code the reason is usually water.
Efflorescence: the wall is telling you something
If you have seen a white, crusty bloom on a block wall or a chalky halo at the base of the stucco, that is efflorescence — soluble salts carried to the surface by moisture moving through the masonry and left behind when the water evaporates. It matters for one blunt reason: you cannot paint over it. The salts keep depositing behind the new film, the pressure builds, and the coating comes off as blisters, often inside a single wet season.
The correct order of operations is unglamorous and non-negotiable:
- Find the water. Failed sealant at a window or control joint, a downspout discharging against the wall, sprinkler heads throwing onto the stucco every morning, a grade pushing runoff toward the foundation.
- Fix the water. Painting while the source is still active buys you a season.
- Remove the deposits mechanically and clean down to sound masonry — not with a metal brush, which scores the stucco.
- Let it dry, then prime for the condition. On exposed or repaired masonry that means an alkali-tolerant primer; Loxon Concrete & Masonry Primer/Sealer tolerates the high pH typical of fresh and patched masonry.
One honest caution, because it comes up on every south-county estimate: elastomeric is not the cure for efflorescence. A high-build, low-permeability coating over a wall that is still moving water can trap that moisture and blister worse than a standard acrylic would. Elastomeric earns its place on stucco with widespread hairline cracking and a dry, sound substrate — we spell out where that line sits in our comparison of elastomeric versus acrylic exterior paint.
What we actually find, area by area
| Area | Typical era | What is usually on the wall | What that changes in the scope |
|---|---|---|---|
| Port Salerno / Manatee Pocket | Mid-century core with later infill | Many coats, patched repairs, heavy salt film | Full adhesion mapping; spot stripping priced by area |
| Rocky Point | Late 1950s onward, mixed CBS | Chalked older acrylic; efflorescence near grade | Chalk-binding conditioner; water source corrected first |
| Miles Grant villas & condos | Mostly 1973–1979, club grounds | Association-scheduled repaints, several palettes in play | Party-wall color match; sub-association coordination |
| Mariner Cay (Manatee Pocket) | Gated waterfront, marina exposure | Heaviest salt load in south county | Coastal-rated topcoat; plan on a 5–7 year cycle |
| Willoughby | Golf club dates to 1988 | Thicker original stucco, generally sound base | Straightforward conditioner plus two full coats |
| Summerfield / Champions Club | Mostly 1990s–2000s single-family homes | Often only a first or second repaint | HOA palette submission; crack and sealant repair |
Villas, party walls, and association repaint cycles
Miles Grant is not one repaint decision — it is many. The club grounds and the streets immediately around them break into separate associations: Miles Grant Condominiums Phase 1 and Phase 2, Fairway Villas, Pine Breeze Golf Villas, Lakeside Villas, Country Club Apartments and Country Club Cove, with Hanson’s Landing and River Pines adjoining. Each carries its own board and its own repaint schedule. When one section repaints and the next section is four years out, we are matching a weathered wall, not a paint chip.
Two rules come out of that. First, we draw the match from the existing adjacent surface and verify it outdoors, on both a shaded and a sun-struck section — a color read under a store light will not hold up on a west wall in July. Second, sheen has to match as carefully as color; satin beside flat reads as two different colors even when the pigment is identical. We then document the exact product, color, and sheen so the next section can match you instead of guessing.
Where a community publishes a governing palette, that specification comes first and the faded wall is the sanity check. Our HOA paint color approval guide covers what these boards want in a submission.
Salt, cycles, and money
Manatee Pocket runs from Port Salerno out to the St. Lucie Inlet, so homes nearest the water carry a genuine marine salt load. That shortens the repaint cycle to 5–7 years near the water against 7–10 years for inland south-county homes on sound substrate — the same split we describe in our guide to how often stucco needs repainting in South Florida. An annual soft wash to strip the salt and mildew film is the cheapest paint-life extension available.
A full exterior repaint with us runs $3,500–$6,500 for a typical single-story CBS home with full prep, correct primer, and two coats. Multi-structure and acreage properties scope above that, and we say so from the walkthrough rather than inventing a bracket. The drivers specific to south Stuart are the ones above: square footage of failed coating that has to come off, and the crack and sealant repair behind the efflorescence. Our exterior painting cost breakdown goes line by line.
Paperwork is mercifully light. Martin County does not require a permit to repaint — painting, papering, flooring and similar finishing work sit on the county’s list of minor repairs exempt from permitting. Your association is the real gate, and we prepare that submission.
