*First, subway tile is the devil. Unless you have a perfectly straight and level wall it will have tons of lippage. That's the word that means the tiles won't be flush with each other. The wall behind the stove is bowed and we knew it and thought we could fix it with the mastic. Nope.
*Second, we picked the wrong grout size. You will always have tons of noticeable lippage with only a 1/16 spacer. Of course that's the one I picked.
*Then I picked the wrong layout. You can't do a 50/50 layout if you've got any wall wobble since tile are thicker in the middle. I was supposed to do a 30/70 which I can't even imagine trying to figure out.
*AND FINALLY, you ALWAYS have to install your overhead lighting BEFORE you tile so you don't get the nasty surprise we got. What to do, what to do.....? We should tear it all out and redo the drywall like we did in the bathroom but right now we've got even more problems to figure out....
It's always something.
