Shadowclad® Ultra Groove
Shadowclad® Ultra Groove combines the look and versatility of traditional Natural Shadowclad products with the time and cost saving benefits of a pre-primed cladding. The primer formulation creates a more consistent and dependable undercoat that's perfect for immediate on-site top coating. The Shadowclad Ultra Groove product features a 9mm wide, 5mm deep profile every 150mm across the sheet.
The product is suitable as an exterior cladding and is available in two treatment options: H3.1 LOSP or H3.2 CCA.
The primed product has a high 60-80 microns film build, and can be up to 2 to 3 times thicker than traditional wet primers.
