Whether you need silicone sealant for a kitchen faucet depends entirely on your countertop material and manufacturer instructions. For traditional stainless steel or porcelain sinks, plumbers putty is typically used under the baseplate. However, if you are installing a faucet on a natural stone countertop (like granite, marble, or quartz), you must use a clear 100-percent silicone sealant instead of oil-based plumbers putty to prevent staining the stone. Verification: Inspect the base seal after installation to ensure a watertight bond against the countertop.
