I have concrete coping which our builder put in with polystyrene forms (Stegmeier). Unfortunately, he used the white plastic tile strip, which I later found out isn't necessary. It's a little while plastic trim cap that sits over the top of the tile (1/4 inch tall) and is bedded in the concrete. Aside from looking terrible sitting in between slate colored tile and brown concrete, it has started to stick out at the corners and is sharp.
I'd like to cut the strip out and wondering if anyone has any experience with this. Once it's cut out I'm guessing that I will need to refinish the interface between the tile and coping possibly with grout and maybe even some type of trim strip. I'm hoping someone here is familiar with this and might have a few suggestions.
