Sauna protective oil SADOLIN CELCO SAUNA 20 1L, wood treatment for sauna interiors, 1 L

SADOLIN CELCO SAUNA 20 is a 1 L sauna protective oil formulated for treating wooden interiors of saunas and steam rooms. The product penetrates into timber to condition and protect benches, paneling and trim exposed to high humidity and temperature changes, helping to reduce surface drying, minimize wear and maintain the natural texture and appearance of wood in wet heat environments.

Advantages

This sauna oil is designed to penetrate wood fibres, providing moisture resistance and reducing the risk of cracking and early deterioration. It leaves a natural-looking finish that preserves the feel and grain of the timber while facilitating easier cleaning and maintenance. Suitable for interior use in steam rooms and saunas, the formulation is intended to extend the service life of wooden surfaces subject to repeated wetting and heating cycles.

Suitable for

• Benches and seating in saunas and steam rooms
• Wall and ceiling paneling made of softwood or hardwood
• Door and trim elements inside humid heat environments
• Renovation and maintenance of existing sauna woodwork

Key specifications

• Form: liquid oil concentrate suitable for brush or cloth application
• Volume: 1 litre
• Intended use: interior wood protection for saunas and steam rooms
• Finish: natural, non-film-forming penetration that preserves wood texture
• Performance: reduces drying and wear of timber under high humidity and temperature

How to use

Ensure wooden surfaces are clean, dry and free from dust, dirt and old peeling finishes before application. Stir the oil if required and apply evenly with a brush or lint-free cloth following the wood grain. Allow sufficient penetration time, then wipe off any excess to avoid sticky residues. For best results, apply at least one full coat and consider a second coat on highly absorbent or heavily used surfaces. Allow complete drying between coats and before exposing the surface to sauna conditions.

Usage recommendations

Test the oil on a small, inconspicuous area first to ensure desired appearance. Maintain ventilation during application and drying. Reapply periodically according to usage intensity and surface wear; inspect benches and high-contact areas regularly and refresh the oil when the wood appears dry or lighter in colour.
