How to re-grouting shower tiles?

Question

Hi team,

The grout in my shower has worn down and I'm wondering whether I can just go over it with a darker grey colour or if the white grout needs to be removed first?

Thanks

Hello @Mary7

In order to get a good secure grout line the old grout must be removed. I suggest using

to remove the remaining grout between the tiles. Give the area a good sweep and make sure that the there are no loose leftover grout in the tile gaps. Once the area is clean you then begin to grout the tiles using

or similar. I suggest using a

and clean as you go to prevent the grout drying up on the surface of tile. My best advice is to seal the grout with
