Concrete paint is for concrete, not drywall. I've never any
"kitche/bath type paint." Unless by that you mean a semi-gloss or
stain type finish. They are sometimes used in those areas,
particularly semi-gloss, because they are easier to clean. However,
the downside is that many drywall bumps, dimples, imperfections are
very noticeable with a semi-gloss.

If it were me, I'd use a latex flat or satin.
