Description
The CT1 Black Sealant & Adhesive 290ml delivers powerful bonding and sealing performance across a wide range of materials. Built with advanced TRIBRID® technology, this product provides superior strength, flexibility, and long-term durability compared to standard sealants.
This CT1 Black Sealant & Adhesive bonds instantly without the need for screws or additional fixings. It performs reliably in wet, dry, and even underwater conditions, making it ideal for demanding environments such as roofing, construction, and external repairs.
The black finish offers a strong, clean look for visible applications while maintaining excellent UV resistance, ensuring the colour remains consistent over time. The formula stays flexible under pressure and resists cracking, shrinking, mould, and bacteria.
CT1 is also odourless, solvent-free, and paintable, making it suitable for both interior and exterior use where performance and finish matter.
This product is also available in White, Clear and Grey
