Grout repair results. I think I do not terribly for it being my first time. Obviously I chose too light a color, but there were only two of this grout to choose from that were in the wheelhouse, and some reviewers had indicated that it dries darker. I didn't really care about matching anyway.
Most of the places where it looks like I have grout on the tiles are scratches from scraping out the old stuff. I will never do that by hand again!
@voltronic looks great! i had a similar job several years ago, dremmel grout remover bit was a lifesaver. I also only did grout and it's held up really well, much better than whatever the builder did anyway.
