Grout question

[Little5]

Hi, They say there's not such a thing as a silly question so dont get on to me. if the grout line is too deep can you "fill it up" after its dry? or is there any drawbacks to doing this.
its mapei grout im using.

How long ago was it grouted?

Take it you used to much water cleaning off?

How wide are the joints?

How deep are we talking.....? Generally, it's normally only the thickness of the tile and adhesive at most!

Also how short is the joint from where you want to be?

How many square metres of tiling & size of tile

so its not fully cured then worth a shot then, rather than having to rake out and do again (NIGHTMARE!)
