Shower corner grout? - Tile Advice

[mac456]

Hi Guys,

So I have not long been in this house and I was recently going to re-seal the shower but I have noticed that they have used grout on the internal corner which has a hairline crack at the very top.

On another forum someone has basically said that silicon should've be used for the corners and not grout.

So what is the best way to tackle this?
Should I cut all the grout out and start again with silicon?
How hard is this job (I've never done anything like this before)?
I am thinking of getting this tool below to scrape the grout out?

Thanks



Should there be silicon between the pattern?

Anyone? Can I just seal over it with silicon?

If you go over the grout with silicone it will eventually fail, best bet is to try and get the grout out and use a decent brand silicone.

Thanks, I'll give it my best shot at removing the grout

Rake out as much as possible without damaging the tiles.
Bead up with quality Dow Corning, Mapei etc,..
