Installing faucet on new granite.

We are having new granite tops installed. I have a new single hole faucet. I have read that plumbers putty stains granite, however putty is all I have ever used. Should I be concerned?

Some faucets come with a gasket that requires no plumber's putty at all. There are some types of plumber's putty that are listed as no-stain (i.e., they don't have oil in them). Best to test on a scrap first. Some granite is so dense that it's pretty impervious to pretty much anything, some can easily be stained.

I made the mistake of actually believing that and ended up with a real problem. I had to remove the faucet and make up a poultice to draw out the stain.

Testing on a scrap may or may not work depending on how long you wait. My stain took a long time to appear.
