I have a leopard concrete garden statue that was given to me by my neighbor that has a broken foot and log. I want to repair it and paint it. It also has been weather eroded so I need to recover it as well. I was wondering if I could mix up concrete, add sand and concrete glue in the mix? I know I will have to put concrete glue to the top of the statue to help bond the mix to it. I hope someone can answer my question.
