The Cedartone Exterior Wood Stain by TWP® is a 1-gallon exterior wood finish for protecting and enriching the timber on an outdoor sauna. This EPA-registered, low-VOC preservative penetrates deeply into exterior wood to help resist decay, mold and structural damage. It is formulated to keep boards stable through freeze–thaw cycles and harsh weather. It works on barrel, cabin and custom-built sauna designs. Ships in original TWP® packaging.
The semi-transparent formula adds a warm cedartone hue while letting the natural wood grain show through instead of hiding it under a heavy surface film. UV-absorbing pigments and moisture-repellent ingredients work together to slow graying, fading and warping over time. The stain can be recoated as needed with minimal prep, so refreshing the color and protection is straightforward. It is intended for exterior surfaces only and should not be used on interior sauna elements such as benches or walls.
