Huge brick 70's fireplace: can I "tuckpoint" myself?

by Lynne Polelle
I plan to milkpaint my enormous 70's brick fireplace of tumbled bricks to lighten it up. However, the original tuckpointing is deeply recessed between the bricks and its cement. I would like to bring it to the surface with something lighter and less industrial looking. Can I do it myself with some kind of caulking?
