The CT1 Sealant for Fastensol A-Slate is a high-performance adhesive and sealant specifically recommended for use with the Fastensol A-Slate roof hook system. It ensures a waterproof, weatherproof bond between roofing components and maintains the integrity of the roof when hooks are installed under slates.
CT1 is known for its excellent adhesion to virtually any surface without the need for primers. It remains flexible, resists vibration, and offers outstanding UV and chemical resistance—making it ideal for outdoor use in solar PV installations. Unlike standard silicone or mastic products, CT1 won’t shrink or crack over time.
This sealant is critical when working with slate roofs, where water ingress prevention is essential. Apply it beneath or around roof hooks to create a watertight seal that protects both the mounting system and the building structure.
