Thanks for checking in and thanks for relaying the pointers on finishing the foundation. I think I am going to do parging over the treated plywood like you explained. I talked to someone else about it as well and they pointed out that once the foam is covered by the plywood there won't be a big rush to finish the parging because the foam will be protected. Which is good because with the winter weather I pretty much have to wait until spring to do it. Plus it will be one less thing I will need to rush to get done.
