FIRST remove all the dirt, grime and soot.
Paint products, use a good quality latex primer like zinzer bin, then a good latex interior semi gloss paint.
Apply two or three coats of the primer, then two coats of the finish coat.
Before you paint, caulk in any cracks or chips that you want repaired.
Will turn out great. The more coats you apply the smoother and better the job looks.
