Hi all, I've just had a completely new bathroom installed including plasterboarding the walls that were in a pretty bad state.
I've recently noticed I'm getting bits of black mould on the shower grouting, The grouting on the walls and flooring also goes dark when wet even though it's been painted over with water repellent.
Has the wrong grout been used?
Shouldn't it have been waterproofed grout.
My kitchen floor was tiled over 10 years ago and I've no problem with that.
Thanks
