Hello! Now I'm going to plaster my basement wall, we've just bought the house and the previous owner just applied regular filler, renovation wallpaper, and paint on the concrete, which caused the moisture to remain. The house is otherwise drained. Now I've removed and knocked off all the old filler and loose mortar, concrete. How should I proceed now? I need some kind of filler before I start the actual plastering. I’m considering using lime plaster as the top layer. But what should I fill with before the plaster itself? Pros/cons between different brands of plaster? Tips and tricks? Feel free to give ideas on plaster/mortar that are suitable for a basement environment.
