plumber putty vs silicone on silgranit sink???

12 years ago


My granite is coming in this Friday. We are having a silgranit double 1 and 1/3 anthracite flush undermount put in. I read a while back that silicone is to be used and NOT plumber putty.

Please can someone explain to me where the silicone will go. Is it to glue the sink or to seal it? I am worried the granite guy will not know about this. Is this common knowledge? Should I be papared and have some silicone ready if the granit guy does not know about not using plumber putty? And what kind of silicone?

Thank you so much for all of your expertise. My DH is impress with all the knowledge I have on different issues and it's all because of this wonderful web.
