Benjamin Moore vs Sherwin-Williams for NB exterior painting — which brand performs better in Maritime climate?

Both Benjamin Moore and Sherwin-Williams are excellent choices for New Brunswick exterior painting — the honest answer is that either brand’s top-tier 100% acrylic latex will hold up in Maritime conditions, and the better question is which product line fits your specific situation.

That said, there are real differences between the two that matter in NB’s climate. Benjamin Moore Aura Exterior and Regal Select Exterior are known for exceptional colour depth, UV resistance, and outstanding adhesion on the wood siding and clapboard that makes up the majority of older homes in Moncton, Saint John, and Fredericton. Sherwin-Williams Duration Exterior and Emerald Exterior compete directly, offering excellent flexibility and moisture resistance, and Duration in particular carries a lifetime warranty for owner-occupied homes. Both products run $65-80/gallon at their respective stores.

The Maritime climate stresses exterior paint in three specific ways that should guide your product choice: freeze-thaw cycling (NB sees 100+ freeze-thaw cycles annually in many areas), coastal salt air exposure, and high seasonal humidity. For freeze-thaw performance, 100% acrylic latex from either brand performs well because the film stays flexible rather than becoming brittle like older oil-based paints. For salt air environments — coastal Saint John, Shediac, Baie Verte, and the Fundy shore communities — look specifically for products marketed as moisture-resistant; Sherwin-Williams SuperPaint Exterior and Benjamin Moore ben Exterior are solid mid-range options for protected areas, but for exposed coastal elevations, step up to Aura or Duration. For UV resistance on south- and west-facing walls, both Aura Exterior and Duration Exterior use advanced pigment technology that holds colour significantly longer than entry-level products.

Availability is a practical factor in NB. Sherwin-Williams has dedicated stores in Moncton, Fredericton, and Saint John where staff know the product line well and contractors can open accounts for volume pricing. Benjamin Moore is sold through independent paint retailers across the province, including smaller communities where Sherwin-Williams doesn’t have a location. If you are in Bathurst, Miramichi, or Woodstock, Benjamin Moore’s independent dealer network may give you better local service and access.

One tiebreaker worth considering: contractor familiarity. Most NB painting professionals have a strong preference for one brand or the other based on experience, and they typically get better pricing through their trade accounts. If you are hiring a painter, ask what product they plan to use and why — a contractor who confidently specifies a premium product by name and explains the sheen and formula choice is demonstrating real expertise.

For DIYers planning their own exterior project in the May-October window, either Sherwin-Williams Duration Exterior or Benjamin Moore Aura Exterior will give you a durable, beautiful result on NB clapboard, cedar shingle, or wood trim — provided the surface prep is thorough. No premium paint will compensate for painting over damp wood, peeling existing paint, or skipping primer on bare wood.
