New tiler mistake

I searched the forums and could not find the answer to these two questions.

Back story: I tiled my sister's backsplash with subway tile in a brick pattern. I leveled the tile to true level and, when I was done, saw that one side of the counter had a 3/4" gap while the other side was down to 1/8" gap. The countertop is concrete covered in some sort of soft type epoxy.

Questions
1.) How do I "fix" this? I cannot remove the tile without destroying the drywall which is not an option. I can't raise the countertop either.

2.) Will decorative quarter round go over the gap? I mean place the top of the quarter round onto the front of the tile and then the bottom right onto the countertop?

I am desperate.

That's about all you can do now. A quarter round or a listello. Problem is it's hard to hide 3/4". How the heck did you.? Didn't you start at the bottom and work up?

And why not? Shoe moulding covers a lot of uneveness after a hardwood floor is installed over unplane flooring so this should not be any different. If it looks good to you then do it. Conrete counter sounds like it bellied in a few area. Professionally this would have been seen before hand and base tiles trimed to fit but if she likes it do it. Remember thinset and matching caulk to do it properly. Exterior walls are the first to show signs of movement:

No backsplashes with concrete tops either, which in turn makes it a harder install. Good luck my friend and hope you get your cheque

My first tiling job ever and, for th emost part, it looks great. I got my gap correct on one end of the counter (about 1/8") and then began laying the tiles. When I got to the other end of the counter, I was a long way off from the counter top.

John K - when you say "no backsplashes with concrete coutner tops", is that a general rule or what'd you mean by that?

"Backsplashes" are the 4" tall pieces along the back wall. Some are granite,laminate,tile. Mostly made of the same material the counter is made out of. Of course its real tough to make a concrete backsplsh

Ah! Ha ha, I know what you're talking about now, I was just thinking the whole tile thing I just did was the backsplash! I get it now.

You could buy a compatible bull-nose to be installed on top of the new tile you just installed. This would cover the gap you let happen. This time (with the bull-nose) be sure to level the top of the bull-nose but cut the bottom of the bull-nose to match the slope of the counter top. Begin at the end where the gap is biggest and work up-slope cutting as you go.
