Iím afraid that most Portland-based stucco products will require something to bond to, either a porous surface, such as unpainted cinder block, or some kind of wire mesh attached to the surface.
However, since you are talking about interior, there are materials you mix with paint to give that stucco-look in relatively dry (interior) environments. Just go to your local home or paint center. They can show you. Another favorite is mixing drywall compound or sand with paint. That will give you a stucco look.
However, is this a basement? Just curious since you said interior cinder block. A basement may be too damp for any paint products to work until you seal the cinder block first. Again, ask your local paint/home store representative.
