Do not oil, paint or stain the inside of your sauna. This way, the wood continues to breathe and you prevent mold and rot.
No, the saunas that you purchase from Welvaere have to be on the inside not treated to become. In fact, if you do this, the wood can no longer breathe and there is an increased risk of mold and rot.
When you close the wood with oil, paint or stain, the moisture that is released in the sauna can no longer go out through the wood. It can then only leave through the vents. As a result, moisture remains in the wood and causes the rotting process from within.
This simple maintenance keeps the inside of your sauna looking fresh and well-kept for years, without the need for oils or paints.
