The Dark Oak Exterior Wood Stain by TWP® is a 1-gallon semi-transparent stain and preservative made for exterior sauna wood surfaces that need long-lasting protection. This EPA-registered, low-VOC formula penetrates deeply into the grain to help keep wall and trim boards structurally sound through rain, sun and changing temperatures. It also resists decay and mildew, and it holds up in regions with harsh winters. It works on barrel, cabin and custom outdoor saunas, as well as other exterior above-ground wood such as fencing, decking and siding. Ships in original TWP® packaging.
The semi-transparent formula adds a rich dark oak tone while keeping the natural wood grain visible. UV-absorbing pigments reduce graying and color washout, and moisture-repellent ingredients help limit swelling, checking and discoloration. Final color can vary depending on the wood and how the stain is applied. The stain can be recoated without aggressive stripping, which makes refreshing the color and protection straightforward. It is intended for exterior use only and should not be used on interior sauna surfaces.
