Grout going off too soon.

[Spencer]

Ive just grouted up a simple splash back . Four M2. The issue I have is that no sooner had I finished grouting, 10-15 min. The grout had gone off rock solid? I used Mapei which incedently I prefer. I managed to clean it back somewhat, but the grout lines are still heavy. Can anyone suggest a method of reducing the grout thickness, without raking out and re-grouting?

Thanks
Spencer

Could try sand paper.

Wouldn't want to risk scratching tiles, but thanks.

Sand paper has so many uses 😉 but it will actually scratch porcelain....I know 🙁😉

Was thinking sandpaper folded,using the edge to rub on the grout line, not on the tile face. If that makes sense.
