Repairing Cracked Grouting

[Jokester]

The grouting between the tiles in my shower has cracked - can it be easily repaired or does it need to be redone?

I think it's been caused by settlement rather than it leaking behind the tiles.

Probably best to remove it and re do from scratch tbh or you could try and just fill the cracks but they may return?

redone is alway best way in long run. if you dont have time to do the job properly. you can apply the thin layer of silicone over the cracks but it'll probably last no more than a month
