I reset all of our flagstone coping. It is time now to tuck in material into the joints. On our flagstone retaining walls and previously in the coping joints the material there is texture / looks like there is some aggregate maybe? I did a test with some type s mortar and its not the same and definitely not what I want, it is very plain with no texture.
Any idea what products I need to use ?
