If you leave the epoxy smooth new glue will have a bad time sticking. Use a knife to add some scratches to the parts being glued. No need if the wood is bare however the glue is what you need to rough up. Drilling small holes for the glue will penetrate will also help with strength. Should be an easy fix.
