Benjamin Moore Aura, Sherwin-Williams Emerald, Sikkens, Cabot — what to specify and what to avoid.
If you're hiring an exterior painter in Connecticut and they don't volunteer the specific paint line they're going to use, that's the first red flag. The paint isn't the largest line item on an exterior estimate — but the wrong choice will cost you 4–6 years of finish life. Here's what 23 years of New England exterior projects has taught us about which paints to specify and which to walk away from.
Three forces destroy exterior paint in Connecticut: freeze-thaw cycles (30–40 per winter inland, slightly fewer on the coast), UV (highest on south- and west-facing walls), and moisture (driven by humidity, dew point, and direct rain/snow exposure). Coastal towns add salt-air corrosion, which strips painted metal and accelerates failure on south-facing siding closest to the water.
The job of premium exterior paint is to flex through the freeze-thaw cycles without cracking, hold pigment against UV, and shed water without absorbing it into the substrate. Cheaper paints fail at all three.
Our default for most premium full repaints. Self-priming on previously-painted surfaces, excellent fade resistance, and the deepest color saturation of anything in this tier. We use Aura on shutters and front doors even when we're using a different line on the field. Expect 10–12 years on north-facing walls, 8–10 on south.
The closest direct competitor to Aura. Slightly lower price point, very strong adhesion, and excellent for HardiPlank and fiber-cement substrates. We default to Emerald when the home has more fiber-cement than wood.
For cedar shake or shingle that's getting stained instead of solid-painted, Sikkens Cetol SRD Plus is the gold standard. The semi-transparent options preserve the wood grain; the solid Rubbol option for cedar that's beyond restoring the natural look. Plan a maintenance recoat at year 4–6 to keep cedar looking right.
One step below Emerald in price and finish quality. Acceptable when budget is the main constraint and the substrate is in good condition. Expect 7–9 years.
Reasonable workhorse. Not the level of Aura but well above contractor-grade jugs. Good for trim and shutters when the field is being done with a higher-tier line.
Our go-to for deck repaints and porch ceilings. Wears in a more uniform way than house paint when foot traffic is involved.
"Contractor grade" 5-gallon jug paint at $35–$45 a bucket is what undercut quotes are usually budgeting for. The pigment volume concentration is too low to hold color. The resin matrix is too brittle to flex through CT freeze-thaw cycles. The result looks acceptable for one summer and chalks heavily by year three. If a quote you've gotten is in the $4,000 range for a full 2,500 sq-ft repaint, this is what's being budgeted.
Behr Marquee, Valspar Duramax, and other mass-market lines: better than contractor jugs, but not premium. They'll perform well for 5–7 years and then start to look uneven on the harshest exposures. We won't specify them on premium projects.
A written estimate should always say:
| Surface | Default product | Why |
|---|---|---|
| Wood clapboard / HardiPlank field | BM Aura Exterior or SW Emerald | Color depth, freeze-thaw resilience |
| Cedar shake / shingle (stain) | Sikkens Cetol SRD Plus or Cetol DEK Finish | UV protection while preserving grain |
| Cedar shake (solid color) | BM Aura Exterior or Sikkens Rubbol | Top adhesion to weathered cedar |
| Trim, fascia, soffit | BM Aura Exterior | Crisp finish, edge retention |
| Doors and shutters | BM Aura Grand Entrance or Aura Exterior Satin | Self-leveling, scratch resistance |
| Decks (solid color) | Cabot Solid Color Acrylic Stain | Wear resistance under foot traffic |
| Stucco | BM Aura Exterior or SW SuperPaint | Breathability + crack bridging |
| Caulk (universal) | SW Loxon XP or Sashco Big Stretch | Paintable, freeze-thaw flexible |
| Primer (bare wood) | Zinsser Cover-Stain Oil or BM Fresh Start | Tannin block + adhesion |
Both are excellent at the premium tier. Benjamin Moore Aura wins on color depth and is our default; Sherwin-Williams Emerald wins on fiber-cement adhesion. The bigger driver is which line within each brand — Aura beats SuperPaint by a wide margin.
Properly applied two-coat Aura or Emerald lasts 10–12 years on north-facing walls and 7–9 years on south- and west-facing walls. Cedar stain (Sikkens) needs a maintenance recoat at year 4–6 to stay looking right.
No. One coat doesn't reach proper film thickness, never colors-out evenly, and never lasts. The paint manufacturer's own warranty requires two coats. If a contractor proposes one heavy coat, decline.
Paint forms a film on top of the substrate. Stain penetrates into the wood. Use paint when you want a solid color and a durable shell; use stain when you want the wood grain to show through. Cedar shake and shingle is the most common stain application in CT.
