Sink install
 
I'm setting a new sink, it's granite. It's an above mount that will be sitting on a granite tiled counter top. Should I use plumbers putty or caulk under or around the sink? I would think I need to caulk around the sink. Also when I install the strainer and garbage disposal should I use plumbers putty under the lip? Thanks for advice on this.

I like silicone myself

I'd use the putty in a thick continuous rope around the underside outer edge - don't skimp on it. You shouldn't have to caulk it. The same with the strainers - tighten them then run hot water and snug them down another quarter to half turn.

I have seen putty stain items.

Use clear silicone and if you need to find a color that matches.

I hardly use putty on anything. Ask your granite supplier. Many companies will void any warranty (if any) if putty is used

Thanks guys. Think I'm going to use putty for the strainers and silicone for the sink unless someone says either is a bad idea to do.
