Water-based varnish for the protection of sauna wood panels against the effects of moisture and dirt. Can be used to protect walls and ceilings in saunas and their antechambers and changing rooms. Cannot be used for sauna sweating shelves and benches. Can also be used for varnishing mineral surfaces, such as concrete, plaster and bricks, indoors in cases where the surface is not subject to intense mechanical action, for example, for finishing the walls.

The varnish is semi-transparent during application. After drying, it becomes fully transparent and forms a semi-gloss film. Drying time at 20 °C is 1 hour per coat. Apply the varnish on clean and dry surfaces with a brush or roller in 1–2 coats, if the air temperature is not lower than +5 °C. Stir the varnish before use. The varnish is ready to use and does not need to be diluted. Varnish consumption is 10–15 m²/l per coat. Wash used tools with warm water and soap after use. Store in a tightly closed container at a temperature not lower than +5 °C.
