I had some cracking in my tiles in the shower enclosure (there was a slight leak from where it was installed incorrectly and this caused the backing board to expand in areas and some of the grouting cracked)
I'm just starting the unenviable task of trying to rout out all of the old cracked grouting.
How long should I leave it to dry out for before I start regrouting?
The grouting that's coming out doesn't seem damp - it's just let some water in (has been covered up with gaffer tape to try and reduce the amount of water going through)
It's already been done once but started to crack again after about a year.
