brown or clear neutral cure 100% silicone around the rim of 
the sink to form a water tight seal. See our Complete Silicone 
InstallationKit(#SINSTALL-101) for Copper Sinks.

Sinkology Copper Armor care kit (#SARMOR-101) or high quality 
carnauba wax. 
Important
Sinkology bathroom drop-in sinks do not use mounting hardware. Our 
preferred mounting method requires expanding foam and 100% silicone 
to secure your copper sink into place.
