Tikkurila Supi Black Sauna Wax (1 Liter) is a water-based, natural wax treatment developed to enhance and protect interior sauna wood while achieving a refined, contemporary look. The wax penetrates deeply into the surface, forming a silky matte finish that repels moisture and resists dirt without obscuring the wood’s natural texture. Its modern black color adds depth and contrast, making it perfect for darker, design-forward sauna spaces. Suitable for benches, paneling, ceilings, doors, and window frames, this eco-friendly formula is low-odor, fast-drying, and easy to apply by brush or cloth. The result is a durable, easy-to-maintain surface that combines aesthetic appeal with long-term protection in high-humidity sauna environments.

  • Protective silky matte finish – Creates a smooth, low-sheen surface that preserves the natural character of the wood while giving it a refined, premium look.
  • Natural wax penetration – Wax-rich formula soaks into the wood to reinforce fibers, improving resistance to moisture, sweat, and daily use in sauna conditions.
  • Multi-surface versatility – Engineered for benches, walls, ceilings, doors, and window frames so you can protect the entire sauna with a single product system.
  • Modern black color – Ready-mixed tone delivers an even, contemporary finish that suits dark-sauna designs and creates dramatic contrast with light woods.
  • Water-borne, eco-conscious formula – Easy to brush or wipe on and simple to clean up, supporting healthier indoor air and long-lasting durability.
  • MPN: Not specified
  • Compatibility: Interior wood surfaces (coverage varies by wood type)
  • Part Type: Water-based wood coating/finish
  • What’s Included: Liquid coating (various package sizes)
  • Coverage: Approximately 107–139 sq ft per gallon (varies by wood type)
  • Drying Time: Dust-dry in 30 minutes–1 hour; ready for use in 24 hours
  • Density: Approximately 8.35 lbs/gal
  • Volume Solids: 24%
  • VOC Content: Max 130 g/l (2010 compliant)
  • Sizes Available: 7.6 fl oz, 1 qt, 0.7 gal; standard colors also in 11.3 fl oz, 1.05 qt, 0.8 gal

APPLICATION INSTRUCTIONS:

  1. Preparation:Ensure the surface is dry, clean, and free of dust. For new wood, wet slightly, let dry, sand, and remove dust.
  2. Application:Stir thoroughly. Apply with a foam brush, sponge, or synthetic bristle brush, along the wood grain. Avoid applying too much wax, as this may make the surface slippery.
  3. Drying and Maintenance:Allow to dry fully for 24 hours before sauna use. Maintain with Supi Saunapesu cleaner as needed.

    Love this wax

    This wax was perfect. My daughter and I applied it quickly. It went on great and a little goes a long way! I ordered two jugs because our sauna is 8 by 6 plus 4 by 6 changing room and we only used half of one.

    Just In Time For Christmas

    Purchased several items for my sauna build from The Sauna Place. Tikkurila wax is the best available and difficult to find. The Sauna Place had everything I needed and was quick to ship, well packaged and arrived very quickly. Great job!
