1. No, the Green Building Supply Penetrating Concrete Sealer is a penetrating product and it will not seal concrete that has been covered (with paint, etc.) or already sealed. The concrete needs to be raw, clean, cured, and otherwise uncovered and needs to be porous (so not polished/not power troweled). If there is doubt as to the porosity of the concrete, we sell samples so you can test. 2. Yes, after the concrete is sealed with the penetrating concrete sealer you can apply paint over that. 3. Yes. Any acrylic based paint will work over concrete that is sealed with GBS Penetrating Sealer. We'd recommend the AFM Safecoat Transitional Primer, followed by AFM Zero VOC Paint.
