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

If you didn't get it smooth 1st time it's too late now!

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

 

[Bond]

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

Dremmel.

Are we talking metro tiles?

Of course...... it's against the law to use Any other tile in a kitchen..!!

I'd try an an acid based cleaner.

A (very) steady hand and a hardibacker knife?

The dreaded metros + fairly fast setting grout + perhaps a warm room! You could spend all day trying to sand/scrape/dremel/fein and still only achieve an average finish. You might find it easier to knock them off and replace seeing as they are cheap.

ucp, small ceramics and a warm environment can easily catch you out. I think Rookery's option is best course and use a different grout next time . Grout 3000 gives plenty of time with ceramics.
