Copper & Zinc Silicone Sealant 310ml

The Coppa Gutta Copper & Zinc Silicone Sealant is a high-performance, neutral-cure sealant specially formulated for use with copper and zinc rainwater systems. It provides a long-lasting, watertight bond between joints, fittings, and gutter sections — ensuring durable, professional results that stand the test of time.

Designed to prevent staining, corrosion, and discolouration, this premium silicone is ideal for sealing joints in gutters, outlets, and downpipes. Once cured, it forms a flexible, weatherproof seal that accommodates natural expansion and contraction, guaranteeing long-term performance in all weather conditions.

Each 310ml cartridge is easy to apply using a standard sealant gun and delivers a lifespan of up to 25 years, offering exceptional reliability and low maintenance for both copper and zinc installations.
