Provided the stone is porous (a critical point), we would recommend you use GBS Penetrating Concrete Sealer instead. Once that has dried, you can paint over it if you wish with acrylic paint such as AFM Safecoat Concrete Floor Paint.By comparison, Penetrating WaterStop is not something that plays along well with paints.
