We're looking to finish the basement in our 1920s home, and the parging on the basement walls is crumbling and flaking like crazy. Based on my research, it looks like the best route for finishing the walls is adhering XPS insulation directly to the foundation walls. Can I do this over the parging? If not, what is the best way to remove it?Thanks for your help! via /r/DIY https://ift.tt/2J13QDM
