Sika SikaSeal® General Purpose Silicone Sealant – Black – 260ml

The Sika SikaSeal® General Purpose Silicone Sealant – Black – 260ml is a versatile, multi-purpose acetoxy cure silicone designed to provide a strong, permanently flexible and waterproof seal across a wide range of domestic, commercial and industrial applications Featuring a fast-curing formulation, the sealant forms a durable, flexible bond suitable for sealing joints and gaps in areas exposed to moisture. Its integrated anti-fungal formula helps protect against the growth of bacteria, mildew and black mould, making it particularly suitable for kitchens, bathrooms and other high-humidity environments.

The silicone offers excellent versatility, making it suitable for sealing around baths, showers, basins, worktops and laminates, as well as bonding PVCu trims, cladding and panels. It can also be used for aluminium gutter sealing and general draught-proofing applications. Designed for convenient application, SikaSeal® features a low-viscosity formulation for smooth dispensing and a skin formation time of approximately 15 minutes at 20°C. Once cured, the sealant maintains flexibility across a service temperature range of -30°C to +150°C, providing reliable performance in varying environmental conditions.

Supplied in a 260ml black cartridge with an application nozzle, this general-purpose silicone sealant is suitable for professional installers, maintenance teams and construction applications.
