That high pH might be because your concrete is less than a year old. If this is the case, you could use Green Building Supply pH Reducer. You will need to get the pH down to between 7 and 9 before using the Penetrating Sealer. (and we applaud that you tested your concrete's pH! bravo!)To answer your other question, yes, you can paint over the GBS Concrete Penetrating Sealer with any good acrylic latex type paint. Follow directions, and be sure Penetrating Sealer is thoroughly dry before coating over with paint.
