Protect your cedar wood from water damage over time with our Sauna Guard Stain Preserver, by Conpert. This recipe was brought over from Finland by Bert Jalasjaa, the Author of “The Art of Sauna Building”. The preservative is a clear finish that seals moisture from entering the wood. This formula is designed for use in the high temperatures of the Sauna, without any off-gassing or loss of protection. Popular for Bench tops or other high traffic areas and recommended for Commercial saunas. Not available in winter months as the preservative can’t freeze.
