Bullnose - also for any outside corners! I have an outside corner on my backsplash - there's a concrete post in the corner that we had to tile around. I totally forgot about it when I was ordering tile (which is funny, because I was obsessed about my outside corners in the bathroom). Well, the tiler asks what I want to do with the corner... he's got these vinyl strips he likes to use for corners. I had already nixed the vinyl strips in the bathroom - I think they look cheesy. I asked if he could miter the corners (cut the edge of the tile in a diagonal so the two corners line up). Well, the corner is exactly the same size as the tile so there isn't enough overlap to miter them. Fortunately, they were rectified porcelain tiles with a nice factory edge, so he was able to just line up the edges. Doesn't look bad. Sorry for the long story, but the upshot is - don't forget the bullnose! ;-)

Those adhesive dots used by crafters ... even though they are supposed to be permanent, you can yank them off.

Since drywall will be damaged anyway, save yourself time, and cut it out, and put in a new piece of drywall, and tape and mud it and sand and prime. I do have to agree, that the back splash cannot be reinstalled, and that it isnt a very pretty one either. Please choose another backsplash, that actually will go with your kitchen and maybe a bit lighter in color. That one is so in your face, that the rest of your kitchen, isnt what you see when you look at the picture. Sorry you have to do all this extra work. Your kitchen looks very nice. The black sink is just like the one I would like to replace mine with.

meaning, it's not his fault the tiles were glued on the mesh incorrectly. everyone that commented up top said what a horrible job he did installing them because they were crooked. that's why I said, "Hang on". I was letting everyone know that these sheets of mosaics often come crooked. that's what I meant by not his fault. and for the fourth damn time, yes, the installer should have done a few of them by hand. However, should he have taken each and every tile off the sheet and done them one by one??? uh, no. That's the meaning of, "not his fault". Do you actually expect him to do that? Who is in charge of this project? Why didn't they pay attention to how screwed up the tiles were on the sheet? why didn't that person know enough to catch it, advise the homeowner or give instructions to the installer to do what needed to be done?? You're faulting the wrong person. OP hired a company to do the entire kitchen. they are using one of their 'tile guys' on staff. Sometimes you luck out and get someone who's good. Most times you get someone who doesn't speak English and only installs what they're given, without thinking outside the box. they just figure, "this is what boss gave me to put up, i put it up. not my fault if they were crooked". OP said this was a 25K job. how much of that went to the tile install, I do not know. I also think, overall, it's a decent job. there are a few tiles that are off and should be fixed, but if that's all there is, then I wouldn't do a tear out. The way everyone was acting about his install was a bit much. We've all seen horrible tile jobs on here and this is not one of them.
