Greetings all. It's been a while since I have posted, but I'm a very good lurker.

Question: I am installing ¾" x 5" solid oak prefinished hardwood in the foyer and den. In the den there is a traditional brick fireplace and hearth. My question is how to deal with the hearth. I intend to put a single course frame around the hearth. Should the hearth be undercut? If so, by how much and which tool to use. If not, how to treat the joint at the hearth? Base shoe or caulk.

Thanks,
Ted
