  1. No, clean and dry it first ✔
  2. Yes, paint seals it in
  3. Yes, but only caulk works

Why: EPA says not to paint or caulk moldy surfaces. Clean up the mold and dry the surfaces before painting, because paint applied over mold is likely to peel.

Huh, didn't know that: If a moldy item is expensive or has sentimental value, EPA suggests you may wish to consult a specialist.
