Sherwin-Williams Emerald® Exterior Technical Review: Best Exterior Paint Trends 2026
In our 17 years of protecting Northwest exteriors, Emerald® Exterior remains the most durable, high-build coating we have encountered.
Emerald® Exterior bridges the hairline gaps where moisture typically penetrates.
The board pictured below is situated 24 feet above grade. These split cracks are virtually invisible to the naked eye from the ground, yet moisture will inevitably find them. Left unsealed, these cracks lead to substrate saturation and eventual dry rot—a costly repair that many contractors in Kirkland or Bellevue are unwilling to address on a small scale.

Topical Authority: Emerald® in the Pacific Northwest Light
As a leading painting contractor serving Medina, Mercer Island, and Woodinville, we recognize that PNW lighting is unique. Emerald® Exterior is particularly effective here because its high-build nature withstands our constant cycle of overcast moisture and intense UV exposure. While national exterior paint trends 2026 lean toward darker colors, these pigments often face "chalking" in the sun; Emerald’s superior cross-linking technology resists this degradation better than standard resins.
Independent testing by Project Farm highlights how Emerald® interior scores top marks for washability [00:12:34] and coverage [00:06:50]; these same engineering principles apply to the exterior line, providing a barrier that prevents the specific dry-rot issues we see in Sammamish and Issaquah valley homes.
