So my current plan is to use those insofast panels but I want to make sure I don’t create something that will lead to issues down the road. So my question is, if I scrape enough of the loose stuff off, could I put some Drylok extreme on it and then put the insofast panels over the top of it? My thought is that if I do that it should decrease the chance of efflorescence wanting to form there again since the humidity shouldn’t affect it nearly as much.
I am not really sure why it is just that one area for the efflorescence but unfortunately there is no way for me to do anything on the exterior because of a ground level deck that is there.
Here is a picture of the area (the picture uploaded sideways, but you get the idea):
