Sikkens Cetol Deck Ultra – Natural, a premium oil-based translucent stain designed for timber decks, steps and walkways, brings together durable protection and a refined, natural look. This one-pot formula penetrates deeply into timber with a low-build film, so your boards breathe while the coating guards against the elements. The result is a surface that ages gracefully, not by masking the grain but by enhancing it.

• Deep penetration, low film build: seals and protects without creating a heavy layer, preserving the timber’s authentic texture.
• Microporous, breathable finish: allows the wood to breathe while repelling unwanted moisture for long-lasting performance.
• UV Shield technology: delivers extreme UV and weather resistance to slow down fading and wear from sun exposure.
• Wood grain remains visible: a luxurious satin sheen that enhances natural beauty rather than disguising it.
• 2-in-1, no basecoat required: straightforward application with reliable results, simplifying prep and maintenance.
• Mould and weather resistant: engineered to withstand outdoor conditions and physical wear, keeping decks looking fresh.
• 4L, Natural satin finish: a substantial can size that suits larger projects while delivering a refined, translucent look.

Ideal for homeowners and professional builders who demand durability without sacrificing the timber’s character, Cetol Deck Ultra is perfect for outdoor decks, steps and walkways where people live, work and play. The translucent satin finish protects against the harsh sun and seasonal weather while letting the wood’s texture shine through, so your outdoor spaces look welcoming year after year.
