Tikkurila Supi Saunasuoja – Sauna Finish 1L

A Protective Finish for Sauna Walls, Ceilings and Humid Surfaces

Tikkurila Supi Saunasuoja is a protective semi-matt finish designed for wooden sauna surfaces, wood fibreboard and concrete surfaces in humid interior environments. It creates a dirt and water-repellent surface that helps keep sauna walls, ceilings and other timber surfaces looking clean and well-maintained, even under the demanding conditions of regular sauna use.

Supi Saunasuoja contains an anti-mould agent to protect the treated surface, making it particularly well-suited to humid rooms and sauna interiors where moisture and warmth can otherwise encourage surface deterioration over time.

Important: Supi Saunasuoja is not suitable for use on sauna benches. For bench protection, please see Tikkurila Supi Laudesuoja.
