Redwood Exterior Sauna Stain – 1 gallon | Heritage Sauna®

Redwood Heritage™ Exterior Sauna Stain – 1 gallon is a semi-transparent wood stain and preservative created specifically for exterior sauna wood surfaces that need long-term protection. This EPA-registered, low-VOC formula penetrates deeply into the grain to help guard against structural damage, decay, and mildew while reducing the risk of warping from moisture and freeze–thaw cycles. UV-absorbing pigments work to limit graying and fading, supporting a rich redwood tone that complements barrel, cabin, and custom-built outdoor saunas. Its recoatable design makes ongoing maintenance straightforward, allowing you to refresh color and defense without stripping the surface. Packaged in a convenient one-gallon size, Redwood Heritage™ Exterior Sauna Stain – 1 gallon provides climate-resistant performance and an attractive, natural-looking finish for owners who want both durable protection and a warm, inviting sauna exterior.
