Can I apply clear coat on top of epoxy paint on garage floor?

We purchase the epoxy kit but we did not mix A with B. My error. Now I want to protect my floor with some kind of a sealer or concrete protector so the paint wont peal off. My fear is would the sealer or clear coat can I apply on top of the paint. Recommendations please. I dont want to take the whole thing off and start all over again. Thanks
