Product Info

Tikkurila Supi Sauna Wax

Tikkurila Supi Sauna Wax is a water based coating which contains natural wax for use on the interior wood of saunas and steam rooms. The wax acts as a thin stain penetrating the wood to give a natural silky finish. When applied, Supi Sauna Wax will absorb into the wood and form a humidity and dirt resistant surface. 

Supi Sauna Wax is available in a ready mixed white, grey, black or can be tinted to a beautiful range of semi-transparent colours. When applied clear, unlike most waxes, Supi Sauna Wax will not deepen the natural colour of the wood. As with any semi-transparent coating, the finished colour will always depend on the colour of the timber underneath. Always do a test area, before applying to entire surface. 

Supi Sauna Wax is suitable for coating and protecting interior wood surfaces of saunas and steam rooms including; sauna benches, paneled walls and ceilings, doors and window frames.


Prior to application, ensure that the interior sauna surfaces are dry, the temperature of the air at least +5 oC, and the relative humidity of the air below 80%.

Preparation for new clean wood surfaces:

Ensure to remove any dirt and dust, then moisten lightly with water spray, let dry and sand loose wood fiber. Remove sanding dust.

Preparation for old or previously coated surfaces (e.g. with Supi Suana Finsh):

Wash down with Supi Saunapesu Cleaning Agent according to instructions. Rinse thoroughly and let dry. Sand and dust off. If any old substrate traces are left under the wax treatment, the end result will be more glossy than on untreated wood.

Supi Sauna Wax is not recommended to be used on oil-treated surfaces (e.g. with Supi Bench Protection), if oil is not worn off.
Protect floors well before treatment, because Supi Sauna Wax is absorbed easily into ceramic tile joints.


Stir Supi Sauna Wax properly, from time to time also during usage.

Apply one coat of wax along the grain, not using more wax than the wood can absorb. Because the wax is a very thin with a liquid consistency, it is most suitable for application by foam brush or sponge. If too much wax is applied, the surface remains greasy. 

Prior to applying Supi Sauna Wax to the entire surface, ensure to do a trail area on a hidden spot to be sure of a correct colour. The final colour of the surface depends on the wood species. Thermally modified wood surfaces are recommended to be treated with Supi Sauna Wax tinted to colour TVT 318R.

When applying, treat small surfaces in one go to avoid overlapping and large panel surfaces 1-2 panels at a time to achieve a uniform colour.

After application, allow for drying time and Pre-heat and ventilate the steam room thoroughly before use.

Sauna will be ready to use after 24 hours drying time.
