Our varnish is a high quality water-based wood varnish, containing acrylic polymers which assist in keeping the sauna’s exterior wood protected and resistant to dust, sweat and stains. The varnish is a non-VOC (volatile organic compounds) product - and has been tested to establish that there is no significant off-gassing from the product once it has dried. This specific varnish can also be applied on the inside of your sauna.
If you would like to self varnish the inside of your sauna please see the article here.
