What is Thermory Vivid Black? Vivid Black is part of Thermory’s Vivid Translucent collection — a factory-applied wood finish system that delivers a bold, striking translucent black that gives wood a deep, contemporary look while showing the grain. The full Vivid line includes Silver, Black, Coastal White, White Oak, Exotic Brown, and Golden Brown. Recoating interval: 2–7 years depending on UV exposure. What is Thermory Ash? Thermory Ash is dense hardwood with rich grain and superior dimensional stability. Each board is thermally modified at 215°C+ using only heat and steam — no chemicals added. The result: Durability Class 1 (25+ years decay protection), dramatically lower moisture absorption, and superior dimensional stability compared to untreated ash. Material is thermally modified hardwood. How is the finish applied? Vivid Black is mill-applied — the finish is sprayed in a controlled factory environment, not on the jobsite. Mason’s Mill also offers our own mill-applied prefinishing service for projects requiring custom or matched coatings. Factory-applied finishes deliver consistent color across all four faces, eliminate jobsite weather risk, and arrive ready to install.

Specifiers commonly use it for modern exterior facades, accent walls, soffits, and feature siding on contemporary residential, hospitality, and commercial architecture. Why specify a factory finish over field finishing? Even coverage on all four faces eliminates uneven swelling No jobsite cure delays or weather dependency Consistent color batch-to-batch Faster install — boards arrive ready to fasten Longer service life from controlled application What’s in this sample?
