    • Description

      Geocel Marine Silicone is a high-performance, marine-grade silicone sealant designed for demanding environments exposed to saltwater, constant moisture, vibration and UV exposure. Suitable for both professional marine engineers and DIY boat owners, this premium sealant provides exceptional long-term durability and strong, flexible bonding.

      Formulated for use above the waterline, Geocel Marine Silicone adheres securely to a wide range of marine and construction materials including fibreglass, wood, stainless steel, aluminium, UPVC, plastics, ceramics and glass. It maintains flexibility over time to absorb movement, vibration and thermal expansion without cracking or shrinking.

      Available in multiple colours — Clear, White, Black & Aluminium (or whichever your store stocks) — this sealant provides clean, colour-matched finishing for all types of marine repairs and waterproof sealing applications.
