Will blue painters tape damage granite?

Answer 1

Yes. If you leave it on the granite for more than a day or two it will. Now have a brown countertop with a one inch light blue stain on it.

Answer 2

Blue painter's tape should not damage granite surfaces when applied and removed properly. It is important to test a small, inconspicuous area first to ensure that the tape does not leave any residue or interfere with the finish of the granite.
