I don't know about that, but why not shim out the furring as necessary and fasten it?
We didn't really have that issue so I can't give much input there. I'm not sure if thinset would strengthen cracked brick much though. Is it possible to attach in different places or is the whole wall compromised?tmg862 said:Thanks for the feedback. I do plan on leveling the furring strips, but I just wanted to strengthen some cracked and crumbling brick before I put my tapcons in.
