Acrylic lacquer PENTACOLOR Sauna 3 L – clear protective finish for sauna surfaces

Acrylic lacquer PENTACOLOR Sauna 3 L is a waterborne clear protective finish designed specifically for interior sauna and high-humidity wooden surfaces. It forms a durable acrylic film that reduces moisture penetration, resists wear and light abrasion, and preserves the natural appearance of wood used on benches, walls and ceilings in saunas and steam rooms. The formulation is suitable for use on previously untreated and lightly sanded wood; it is applied with a brush or roller and dries to a clear, low-gloss finish that is easy to maintain.

Advantages

This acrylic lacquer provides a transparent protective layer that maintains the wood’s natural colour and grain while offering improved resistance to moisture and surface wear. Its waterborne base ensures low odour during application and easier cleanup compared with solvent-based finishes. The product is formulated for indoor sauna environments and is compatible with typical sauna wood species when applied according to the manufacturer’s surface preparation and drying instructions.

How to use

Prepare the wood by ensuring surfaces are clean, dry and free from dust, oils or previous coatings that are not compatible. Lightly sand overly smooth surfaces and remove sanding dust before application. Stir the lacquer thoroughly before use. Apply evenly with a brush or roller following the grain of the wood, avoiding puddling. Allow recommended drying time between coats and apply additional coats as needed to achieve the desired level of protection. Ensure adequate ventilation while applying and during drying.

Usage recommendations

For best results on sauna benches and walls, apply two thin coats rather than a single thick coat and respect the manufacturer’s specified drying and curing times. Test the product on a concealed area or sample board to confirm appearance and adhesion on the chosen wood species before completing the whole surface.
