Hello, this question is for jumpinjackieflash. Do you know what material was used as grout for your coping (Arizona Buckskin)? Was it concrete? If so, was it colored or the typical light gray concrete color? The second question has to do with the chiseled edges. Did you get them smoothed down or rounded or did you leave them chiseled? If you left them natural, do they seem sharp or problematic? Thanks.
