Give outdoor timber spaces the combination of beauty, safety, and lasting protection with Sikkens Cetol Deck Ultra Slip Resistant in Natural (078 Natural) 4L. This premium oil‑based, translucent stain is engineered for decks, steps and walkways where weather, sun, and foot traffic take their toll. The result is a breathable, micro-porous finish that guards against moisture and UV fade while letting the timber’s natural grain shine through.

Why Cetol Deck Ultra Slip Resistant stands apart

• Ultra‑slip resistant, weather‑ready finish. A textured, micro-porous coating that remains slip‑safe even in wet conditions, while delivering robust protection against rain, mould and general outdoor wear.
• Deep penetration, low film build. The finish absorbs deeply into the timber, creating a durable layer without a heavy film that can peel or crack. This allows the wood to breathe while staying shielded from the elements.
• 2‑in‑1 application—no basecoat required. Ready to use in the can, with no separate priming step needed, saving time and simplifying decking projects.
• Luxurious satin translucence. Enhances the timber’s natural beauty with a subtle, sophisticated satin sheen that’s durable yet understated.
• Strong UV and weather protection. Designed to resist sun‑induced fade and weathering, keeping decks looking fresh longer.
• Breathable, water‑repellent finish. The microporous formula lets the wood breathe while repelling moisture, reducing swelling and checking from humidity and rain.
• Architected for durability under traffic. Built to withstand the rhythms of outdoor use—steps and walkways that see frequent foot traffic stay protected and retain their slip resistance over time.

What you get with this 4 L can

Cetol Deck Ultra Slip Resistant is formulated as a premium exterior timber finish for bare or previously treated timber. The 4 L size covers typical deck projects where you want a natural look with a protective, long‑wearing layer. The product is commonly applied in multiple coats—two coats on bare wood under cover, or three coats as a standalone finish—to ensure even color development and optimal performance. Final colour will vary with timber type, previous treatments, and the number of coats applied.

Smart, simple care and application

Applied straight from the can, Cetol Deck Ultra Slip Resistant requires no thinning. Stir thoroughly before use and brush along the grain for even coverage. Ensure timber moisture content is below 15% for best adhesion, and avoid applying in extreme temperatures or high humidity to maintain film integrity. After the first coat dries, a second or third coat as described above builds the protective, slip‑resistant film without creating a heavy, opaque layer. Maintenance is straightforward: clean, reapply when wear shows, and enjoy continued protection with the same low‑maintenance approach.

Ideal applications and scenarios

Designed specifically for outdoor timber surfaces that demand both beauty and safety, Cetol Deck Ultra Slip Resistant excels on:

• Residential or commercial decks that see regular foot traffic
• Exterior stairs, ramps and walkways where slip resistance matters
• Timber surfaces exposed to sun and rain, needing durable UV and weather protection

Its breathable, microporous nature helps protect against moisture ingress while allowing the timber to expand and contract with changing conditions, reducing the risk of cracking and peeling over time.

Pro tips for best results

- Start with clean, dry timber. If re coating, remove or neutralize previous finishes only as needed.
- Apply with a quality brush along the grain; avoid heavy overlaps to maintain a uniform appearance.
- Allow ample drying time between coats (as recommended on the label) to achieve maximum adhesion and slip resistance.
- For the most natural look, apply the recommended two coats on bare wood or three coats on bare wood for standalone protection. Colour development will depend on timber type and previous treatment.
