Wood finish TIKKURILA SUPI SAUNAFINISH 0.9 L EP — 0.9 L sauna wood finish

TIKKURILA SUPI SAUNAFINISH 0.9 L EP is a water-borne wood finish formulated for interior sauna wood surfaces. Designed for benches, walls and ceilings, this finish forms a protective, breathable film that withstands the temperature and humidity variations typical of sauna environments. It is suitable for both untreated wood and previously finished surfaces, preserving the natural look and grain while making the surface easier to clean and maintain.

Advantages

This sauna-specific finish provides moisture-resistant protection without creating a thick, glossy layer, keeping the wood's natural appearance and texture. The product is formulated to tolerate heat and damp conditions commonly found in saunas, reducing dirt penetration and facilitating routine cleaning. Application results in a surface that retains the warmth and feel of wood while improving its durability and resistance to staining.

Suitable for

• Benches and seating areas in home and commercial saunas
• Wooden walls and ceiling panels in sauna interiors
• Untreated softwoods and hardwoods used in sauna construction
• Previously finished sauna wood that requires maintenance or renewal

Key specifications

• Volume: 0.9 litres
• Type: water-borne wood finish formulated for saunas
• Finish: low-sheen, natural appearance
• Application: brush, roller or spray suitable for interior wood
• Performance: moisture and heat resistant film designed for high-humidity environments

How to use

Ensure the surface is clean, dry and free from dust, grease or previous loose coatings. Sand smooth any rough areas and remove sanding dust before application. Stir the product gently before use. Apply evenly with a suitable brush, short-pile roller or spray equipment, following thin, even coats. Allow recommended drying time between coats; apply an additional coat if necessary to achieve the desired protection. Test on a small inconspicuous area if treating previously finished wood to confirm compatibility.

Usage recommendations

For optimal results, apply the finish in a well-ventilated area at moderate temperatures and humidity. Maintain recommended drying intervals and cure time before heavy use; avoid exposing freshly coated surfaces to excessive heat or steam until fully cured. Regular cleaning with a mild detergent and gentle wiping will help preserve the finish and wood appearance.
