Mapei Grout

We fixed the Polish marble because its hollow grout injected into the borehole and after treatment with the grinding machine, put the grout (Mapei) supposed to be beige and the next day, turning to Rose, Have you any idea why? We used to clean up after Hurricane Mapei grout, lquid Stone cleaner, this product Intesis fuchsia or pink color, like Pepto Bismol color. What can we do to solve this problem? Thank you

You can try to re-injection of a thin layer of grout color regularly on the existing color and hope it holds.
