EIFS EXPERT,
Quikcrete also makes a concrete adhesive that they promote as being a catalyst to help bond new stucco to old concrete/stucco/plaster.
Do you think this is sufficient?
I ask because I have a little different problem. My wife and I paid someone to mud/tape our drywall in our finished basement. There were two areas where we wanted stucco.
One is on an exposed 80 year old concrete foundation wall that was crumbling. I new I needed a bonding agent to hold everything together, but I was unaware of the catalyst to help bond the new stucco to the old concrete. Either way, it worked great.
The second area was on a radiantly heated wall that I covered with concrete board instead of drywall so I would have more thermal mass and it wouldn't break down. The handyman just troweled the stucco (Quikcrete finish coat white) directly on the concrete board without any prep/prime/adhesive. While I was waxing/polishing our newly stained concrete floors in the basement I bumped the radiantly heated wall and the stucco popped off the concrete board in a LARGE area (2ft radially away from the impact site). I didn't hit it that hard and it just erupted off the wall. Now I have to patch, and I would prefer to just put on the bonding agent then new stucco and move on. Do I have a problem waiting to happen if I don't rip off all the stucco the handyman put on and redo it myself?
Thanks,
Chris
