Let me start by saying that I am a newbie at the whole tiling thing. I
just finished tiling my first wall, and grouted yesterday. It turns
out that the guy in the tile shop put the wrong shade of grey on our
order, and now I'm stuck with light grey grout lines instead of a
medium grey that matches the tile. What is my best approach to solve
- I've heard of using a rotary tool (RotoZip or Dremel) with a
reinforced cutting attachment to clean out the grout. Since I have a
RotoZip, this could be a viable solution, however I'm afraid of
damaging the tile in the process.
- I've used a grout saw in the past to replace damaged grout in small
areas, but this would take forever on a wall (some 70 sq ft).
- I've also heard of grout colorants, but they kind of sound like a
coat of paint that would wear off over time.
I'm open to ideas.
