How should I plaster interior walls in the basement? I've been watching videos, but there seems to be a big difference in tradition between Sweden and, for example, England. Here, the plaster is applied and then leveled with a straightedge. In England, it is looser, like yogurt, and is applied evenly directly with a float. Are both methods available in Sweden, or do we only have the kind of plaster that is "thrown" on and leveled?
I'm in the process of removing old plaster/putty that has emulsified with wallpaper and wallpaper paste. It sometimes comes off in sheets. What's left is sandy/dusty plaster on mesh. It's well-adhered but gets dusty when I touch it. As I understand, it should be fine to plaster over it.
