Will this work?
The instructions on the Sakrete product you're thinking of using says;
"DO NOT USE A BONDING AGENT."
Removing the primer won't be easy, plus if I remember you're supposed to apply the patch within 24 hours of the primer, so it should not have been used already. oppps.
I think finding another product made by the same manufacturer, (Custom Building), is the best choice. Don't have an answer right now though.
