Help. Bad grouting. Can it be fixed? - TilersForums.com

[Deleted member 53208]

Is this a bad grouting job due to;
too much water in the grout mix?
not enough grout pushed in?

Is this bad tiling due to;
not measuring before setting?

Is the answer to;
grout over the existing grout (72 hours later)?
pull it down and start again?

Do tilers as a matter of course, grout twice, due to 'shrinkage after first application; especially grey grout with charcoal in it', or is this just nonsense to literally cover up a bad job/ fob us off. (The shop has confirmed that the grout does not shrink).

Is it ok to grout on top of new grout? Will it just chip off?

Silicone still yet to be added btw.
