I have a concrete leaf which had a part broken off. I successfully reattached the broken part with bonding mix. However, I'm not thrilled with it so I thought I'd try to add a layer of quikwall and embed some items in it. How should I proceed with this? Mist the leaf and put more bonding mix on it before the quikwall? Let the bonding mix dry and then add quikwall. The leaf is fully cured so if I add a topping mosaic, will I have to keep that misted and bagged again? Any thoughts, anyone? I'm trying to make a silk purse out of a sow's ear here.
