I have recently laid a quartzon natural stone coping to my pool, during installation someone stepped in a pool of bondcrete and walked across the stone and I am struggling to remove it. Any ideas gratefully received!

That’s tricky, mainly because I don’t know what Bondcrete is. Hydrochloric Acid might work, but try a small spot on an inconspicuous part of the coping first. I’m not sure what quartzon is, but it won’t effect most stones. If it’s organic, a heat gun might work too. But be careful – if you burn it and char it you’ll have ab even bigger problem on your hands
Or you could contact the manufacturer of the bondcrete. They would have people there that know more the chemistry of the stuff than I do that could probably help.
