Yes, you can use plumbers putty on a kitchen faucet, but strictly under the correct circumstances. Plumbers putty is ideal for sealing the underside of the faucet baseplate or escutcheon plate where it meets the top of the porcelain sink deck or countertop to prevent water from seeping into the mounting holes. However, never use plumbers putty on plastic faucet components or porous natural stone countertops (like granite or marble), as the oil in traditional putty can stain and ruin natural stone surfaces. Verification: Check that the putty forms an even, squeezed-out bead around the entire perimeter of the base when tightened down.
