Cedartone Exterior Sauna Stain – 1 gallon | Heritage Sauna®

Cedartone Heritage™ Exterior Sauna Stain – 1 gallon is a dedicated exterior wood finish for protecting and enriching the timber around your outdoor sauna. This low-VOC, EPA-registered preservative penetrates deeply to help resist decay, mold, and structural damage while keeping boards stable through freeze–thaw cycles and harsh weather. Its semi-transparent character lets the wood grain remain visible, adding a warm cedartone hue instead of a heavy surface film. UV-absorbing pigments and moisture-repellent ingredients work together to reduce graying, warping, and fading over time. Ideal for barrel, cabin, and custom-built designs, it can be recoated as needed to refresh color and protection with minimal prep. Packaged in a convenient one-gallon size, Cedartone Heritage™ Exterior Sauna Stain gives health-conscious owners a durable, climate-ready way to maintain a clean, natural-looking sauna exterior.
