Ensure a flawless installation with our color-matched Oil Rubbed Bronze Installation Silicone, specifically designed for copper sinks and drains. Unlike traditional white plumber’s putty, which leaves an unsightly ring, this premium silicone blends seamlessly with our Dark/Brown finished sinks and accessories for a polished, cohesive look.
Copper Sink Installation Silicone (CSIS) is a neutral-cure formula free from harsh chemicals that could react with copper and cause discoloration. Whether you're installing a surface-mounted copper sink, a copper bathtub, or an under-mount sink, CSIS provides a secure bond and a perfect seal.
For under-mount installations, it effectively seals the gap between the sink and countertop, while for surface-mounted sinks and bathtubs, it ensures a strong, lasting adhesion. Additionally, it provides a seamless seal around drains, preventing the mismatched white ring left by conventional plumber’s putty.
