SikaSeal Construction Silicone Anthracite Grey CTR300

The Anthracite Grey SikaSeal Construction Silicone is a premium low-modulus acetoxy sealant designed to deliver long-lasting flexibility, durability, and weather resistance across a wide range of construction applications. Its fast-curing formula forms a waterproof, weather-tight seal capable of accommodating up to 20% joint movement, helping prevent cracking and maintaining a professional finish over time.

Ideal for both interior and exterior use, this high-performance silicone features an advanced anti-fungal formulation that helps resist black mould growth, making it especially suitable for humid environments such as kitchens, bathrooms, and glazing installations. The low dirt pick-up technology keeps the seal looking cleaner for longer, while excellent adhesion to materials including PVCu, aluminium, brick, glass, plastics, and timber ensures reliable performance on a variety of surfaces.

Perfect for perimeter pointing, cap glazing, draught-proofing, and sealing around trims, cladding, and pre-formed panels, the Anthracite Grey SikaSeal Construction Silicone offers a neat, durable finish with faster curing times for improved installation efficiency.
