Protect from frost. Once opened, use the oil during the same painting season as the product properties may change in a half empty can.

Application conditions
During painting and drying the temperature of the air, surface and wood oil must be at least +5˚C, and the relative humidity of the air below 80 %.
New bare wood surfaces:
Clean wood surface from dirt and dust. Moisten it lightly and after drying sand it with sanding paper no 230 to remove any raised wood fibres. Remove sanding dust.

Surfaces treated previously with wood oil:
Wash down with Supi Sauna Clean according to instructions, rinse carefully and allow to dry. Sand, if necessary and remove sanding dust. Remove loose paint with scraper and/or steel brush. If a visible film remains on the wood surface, remove it before treatment.

Mix Supi Floor Oil thoroughly before use and during application.

Apply once with a brush or sponge tightly so that all oil is absorbed evenly into the wood. Wipe off any excess oil after approx. 30 min. Apply evenly in continuous strokes the entire length of board to avoid overlapping. Oil treatment darkens the wood.

Pre-heat the sauna before taking it into use and ventilate well.

Maintenance treatment when needed. Surfaces exposed to continuous moisture stress need retreatment at intervals. 
Cleaning of tools
Wash with soap and water. Tikkurila Tool Cleaner is recommended for removal of slightly hardened wool oil.
Maintenance instructions
Handle new surface with care for approx. 1 week. If needed, the surface can be cleaned lightly with soft brush or mop after approx. 2 days from finishing.

The surface can be cleaned at the earliest after 1 month with Supi Sauna Clean (1-2 dl detergent into 5 liters of water) to allow the product to achieve its final hardness and durability.

Product consumption, when surface is...


Consumption varies depending on the surface to be treated and its condition. Absorption is affected e.g. by the surface roughness, moisture content level of timber and porosity. For example, log surface that has been untreated for a long time takes a lot more wood finish than a new surface to be treated.

When calculating the consumption, note that the consumption for round logs is 1.5 times higher than normal. Please also note the corner joints in the surface area.

Rounding up

As the filling rate is usually 90% (space for tinting), it is good to round up the liter amounts and reserve enough of the product so that the work is not interrupted unnecessarily, and colour will be even.
