Since this might end up being a DIY project. I would like some advice on how to best remove the existing beach pebble stones and the base layer of cement from our fireplace. Our current idea is to remove the beach pebbles to a height of 7' and have cultured stone installed all around the fireplace. Is there another way to have cultured stone installed over what we have? If we were to chip off what we want to remove, would you recommend putting up a layer of durorock and then cultured stone? Is it crazy to even consider trying to remove that? Below is a photo of what we are working with.
