Exposure to varying levels of sunlight and moisture often results in patchy greying and inconsistent tones that can compromise the intended aesthetic.

A Consistent, Pre-Weathered Aesthetic
 

NatureSeal CU is formulated to mimic the natural silver-grey patina that timber develops outdoors, but in a controlled and uniform way. By applying the coating before installation, every façade, whether north or south-facing, will weather at the same rate and retain a balanced tone.

Available in a range of pigments to replicate different stages of weathering, NatureSeal CU can be tinted to achieve subtle warm tones or a complete silvered finish. Our silver pigment is particularly popular with architects who want their cladding to arrive on site pre-weathered, ensuring that the building presents a finished, cohesive appearance from day one.

Why Architects Specify NatureSeal CU
 

NatureSeal CU has become increasingly popular among architects, designers, and contractors for several reasons:

• Reliable, even weathering- Eliminates patchy discolouration across different elevations.
• Mould and fungi resistance - Unlike many other weathering accelerants, NatureSeal CU incorporates advanced biocidal protection, significantly reducing the risk of surface mould and fungal growth.
• Moisture resistance - Enhances the timber’s durability and dimensional stability.
   

This combination of aesthetic control and technical performance makes NatureSeal CU a trusted choice in both residential and commercial projects where natural materials are central to the design.

Preserving the Architectural Intent
 

As seen in the images above, the result is a façade that feels natural, refined, and consistent even as the timber continues to evolve with age. NatureSeal CU maintains the expressive grain of the wood while ensuring that its tone harmonises across the entire building envelope.

This is particularly valuable for complex geometries or multi-elevation designs, where exposure levels vary dramatically. With NatureSeal CU, the timber’s weathering process becomes predictable and beautifully uniform, preserving the purity of the architectural vision.

Sustainable, Durable, and Specifier-Friendly
 

NatureSeal CU complements sustainable design principles by extending the service life of natural timber, reducing maintenance cycles, and allowing architects to specify renewable cladding materials with confidence.

It’s suitable for a range of species, including cedar, larch, and thermally modified timber. It can be factory-applied or coated on site depending on project requirements.
