I need advice on regrouting. The grouting didn't turn out well as it dried faster than I expected before washing.
I applied the grout last week and thought I could live with it, but I'm unsure about it.
Visible up close, but it looks fine from two meters away.
Is a grout rake the way to go, or would acid washing with scotch brite work? With a grout rake, there's a risk of damaging the tiles, right?
