Trying to get ideas on replacing the coping, not sure what to do. I would like a similar bull nose, but I can't find anything.
I know I have to cut off the coping, not sure what to use in its place.
Vinyl liner, fiberglass walls.
That's not true coping you have. That's liner track is the bullnose and concrete is simply poured behind it and smoothed over the top to make a eased edge. You would have to replace the liner track to use a bullnose/fullness coping. Some people use pavers/stone to replace and just but it up to the coping. If this isn't aluminum track it wont hold up and it's hard to tell in pubs but it looks kind of wonky already as far as line level goes. What happened to the missing chunk
