Cuprinol Ducksback 5 Year Waterproof for Sheds & Fences, Herring Grey 5L

Cuprinol Ducksback 5 Year Waterproof for Sheds & Fences – Herring Grey (5L)

Cuprinol Ducksback is a premium wood protection system engineered to deliver long‑lasting, weather‑resistant performance for outdoor timber structures such as sheds and fences. The 5 Year formulation offers an extended protective barrier that safeguards against moisture, UV radiation, mould, mildew and fungal growth.

Key Features of the Herring Grey Finish

• Colour: A subtle, natural Herring Grey tone that blends seamlessly with a wide range of architectural styles while providing a modern, understated look.
• Non‑Drip Formula: Designed for easy application, the paint does not drip or sag, ensuring a smooth finish even on vertical surfaces.
• Matt Finish: The low‑gloss surface reduces glare and offers a sophisticated aesthetic that complements both contemporary and traditional designs.
• 5 Year Warranty of Protection: Guarantees continuous defence against the elements for five years from the date of application, reducing maintenance frequency.

Performance Characteristics

The Ducksback system is formulated with a blend of water‑based polymers, silicone additives and UV stabilisers. This combination creates a flexible, breathable coating that:

• Prevents water ingress by forming an impermeable barrier while still allowing the wood to breathe.
• Resists UV degradation, maintaining colour fidelity and structural integrity over time.
• Fights mould, mildew and fungal growth through antimicrobial agents embedded in the formula.
• Offers excellent adhesion to a variety of timber substrates, including seasoned, untreated, or previously painted wood.

Application Process

The 5 L canister is suitable for medium‑sized projects such as shed walls, roof panels, fence posts and rails. For optimal results, follow these steps:

1. Surface Preparation: Clean the timber surface to remove dust, dirt, old paint or loose flakes. Use a mild detergent if necessary, then rinse thoroughly.
2. Drying Time: Allow the surface to dry completely before application; moisture can compromise adhesion.
3. Priming (Optional): While Ducksback adheres well to untreated wood, priming is recommended for heavily weathered or previously painted surfaces to enhance bond strength.
4. Application Method: Apply with a high‑quality brush, roller or spray gun. For vertical walls and fences, a roller ensures even coverage; for intricate details, a brush provides precision.
5. Coat Thickness: Aim for a uniform coat of approximately 0.2 mm. Multiple thin coats are preferable to a single thick layer, as they reduce the risk of cracking or peeling.
6. Curing Time: Allow at least 24 hours between coats and 48 hours before exposing the surface to rain or heavy moisture.

Maintenance & Longevity

One of the standout benefits of Cuprinol Ducksback is its low maintenance requirement. After the initial application, routine upkeep involves:

• Periodic Cleaning: Gently wash with water and a mild detergent to remove surface grime.
• Inspection: Check for cracks or peeling after heavy weather events; touch up as needed to preserve the protective seal.
• Reapplication: At the end of the five‑year protection period, a fresh coat will renew the barrier and extend longevity.

Compatibility & Versatility

The Herring Grey 5 L is suitable for a wide range of timber applications:

• Sheds: Walls, roof panels, door frames, and decorative trim.
• Fences: Posts, rails, pickets, and gate components.
• Garden Structures: Pergolas, trellises, and garden sheds.
• Outdoor Furniture: Decking panels, benches, and patio furniture (subject to manufacturer guidelines).

Environmental & Safety Considerations

The product is formulated as a water‑based paint, which reduces volatile organic compound (VOC) emissions compared to solvent‑based alternatives. This makes it safer for indoor application and less harmful to the environment. Always wear protective gloves and eyewear during handling, and ensure adequate ventilation if applying indoors.
