What kind of surface leveling is this???
Hello Forum.
I have encountered a type of surface leveling/plastering on several occasions that is extremely porous and fragile. If you take a lump between your fingers, it can easily be crushed into crumbs. It cannot be drilled into or processed... :banghead:
The times I have come across it, it is as leveling on a frame of harder concrete or brick, and always indoors(?!). The material in question has been found in houses built in the 1940s-60s.
Hmm, what is this nuisance of a material called, does anyone know?

Common with very weak concrete as finish.
It is usually mostly sand and quite little cement.
Cement was expensive!
I believe it was rationed shortly after the war.

Probably lime plaster.
All plaster eventually becomes old... Just tear down and apply new plaster... At home, I tore down all the loose plaster behind the wallpaper and slapped on gypsum plaster instead. It has worked great. Houses from the 40s-60s are of course getting old and need some love. If you plaster the walls again, they will last another 40-50 years.
