iLONA SAUNA STAIN  / Painting instructions

iLONA Sauna Stain is a fast-drying and odourless wood stain for treating wooden surfaces in the sauna and shower room, with no plastic agents. Sauna Stain leaves the grain of the wood visible and protects the surface from moisture and dirt. It is suited to old and new untreated wooden surfaces, and surfaces treated with products that do not form a hard coating. It is ideal for the sauna and shower room ceilings and wall panels, doors, window frames and benches. Avoid use on surfaces directly in contact with water, such as around the shower. The product is not suited to surfaces previously treated with paraffin oil or wax. Do not use on floors.



iLONA Sauna Stain is clear, but it can be tinted to the Uula Translucent Interior Colour Chart, as well as to most common translucent colour charts. Please note that when choosing a translucent stain, the colour of the surface and previous treatments affect the end result. Differences in tinting pastes, tinting machines and tinting methods may cause subtle variation in shade.


We recommend a varnish brush or a smooth finish paint brush. The surface to be painted must be dry, the relative air humidity below 80 % and the temperature at least +10°C.
Drying time: Touch dry in approx. 30 minutes and ready for a re-coat after 2 hours.
Drying of sauna benches: We recommend a week of drying time before exposure to any water. The product reaches full durability in one month, during which it is advisable to cover the seating when used.


Stir iLONA Wood Stain thoroughly before and during use. Reserve and mix enough stain for a large surface in order to avoid potential colour variations in different batches. Paint a test patch to ensure the colour is correct and to find the desired level of opacity. The paint attains its true colour once fully dry. Use paint generously, as a dry brush can cause uneven texture and gloss. Paint one board or log at a time. Protect surfaces not to be treated with adhesive tape, paper, cardboard or protective film.

Preparation: Remove dust from the surface to be treated. Wash dirty surfaces with Uula Paint Wash following the instructions and allow to dry thoroughly before treatment.
Clear treatment: Treat the surface with clear wood stain 1–3 times. Sand the surface between treatments and remove dust.
Coloured treatment: Treat the surface with tinted wood stain 1–2 times to the desired opacity. To enhance durability treat the surface 1–2 times with clear wood stain.
