Our Marine & Specialist Sealants range is designed for demanding environments where standard silicones cannot perform. This collection includes high-quality formulations from trusted manufacturers such as Bond It and DOWSIL™, engineered for marine applications, high-moisture environments, vibration-prone areas, and specialist construction needs.

These sealants provide exceptional saltwater resistance, UV stability, temperature tolerance, and strong adhesion to materials commonly used in marine and specialist installations — including fibreglass, stainless steel, aluminium, GRP and coated metals.

Whether you’re maintaining boats, sealing above the waterline, working on caravans, or undertaking technical repairs, these products deliver long-lasting and reliable performance where it matters most.

Explore our range to find marine-grade silicones, RTV formulations, and specialist sealants tailored for unique or challenging environments.
