Sections of the parging on the cinder block foundation wall outside started to fall away over the winter, so this month, I started to knock it away to replace it. Underneath, I found that some of the cinderblocks are starting to spall. In some cases, about 1/8 an inch of the block face would come off with the parging. So my question is, is it OK to just cover this up again with the cement I'm using? (QuickWall from Quikrete) Or do I need to do other repairs first? I'm relatively new to this whole repairing thing, so any help anyone could give is welcome. Thanks!
