Cast Iron (37)

A rich, deep grey that enhances wood grain and adds depth to timber surfaces. Cast Iron (37) is equally effective on steel frames and exterior ironwork, including downspouts and gutters. The bold yet versatile tone provides a striking contrast against lighter colors and works well across many applications. Whether used on wood or metal, it delivers a refined, confident finish. 

For best results, pair Cast Iron (37) with Primer #3, our ready-mixed linseed oil primer formulated for darker tones.
