Tikkurila Supi Floor Oil – Sauna Floor Protection

Premium Protection for Wooden Sauna Floors

Tikkurila Supi Floor Oil is a water-based, natural oil-derived treatment designed to protect and preserve wooden sauna floors and humid interior surfaces. Formulated to penetrate bare and previously oiled timber, it helps shield the wood from moisture ingress, everyday dirt and surface cracking — keeping your sauna floor looking and performing at its best for longer.

Part of Tikkurila's trusted Supi range, this is a professional-grade product used across residential and commercial sauna installations. It sits naturally alongside the wider Supi care range for a complete sauna maintenance routine.

Best For

Supi Floor Oil is ideal for:

• Bare wooden sauna floors receiving their first protective treatment
• Previously oil-treated sauna floors requiring maintenance or refreshing
• Thermally modified timber and hardwood sauna flooring (where manufacturer guidance permits)
• Humid interior spaces where wood requires ongoing moisture protection

Key Benefits

• Water-based formula derived from natural oil components
• Helps protect wood against moisture penetration and everyday dirt
• Can help reduce surface cracking and drying of timber over time
• Suitable for bare, previously oiled and thermally modified wood surfaces
• Penetrates the wood rather than forming a surface film, preserving the natural feel underfoot
• Part of a complete Tikkurila Supi sauna care system

How to Use

Ensure the surface is clean, dry and free from dust, grease and any previous coatings that may prevent absorption. Apply evenly using a brush, roller or cloth, working in the direction of the wood grain. Allow to absorb fully before applying a second coat if required. For full application guidance, coverage rates and drying times, please refer to the Tikkurila Supi Floor Oil Technical Data Sheet (TDS) or contact KeiCo for support.

Good to Know

• Coverage rate: approximately 8–15 m²/litre depending on the porosity and condition of the timber
• Not intended as a surface lacquer or film-forming finish — it is an oil treatment
• Always test on a small, inconspicuous area before full application
• For technical data, safety information and MSDS, refer to the Tikkurila product documentation
