Hi all, I’ve just moved into a maisonette, most likely built around 1950s.
The place was wallpapered and the walls feel solid. (Not drylined and is not plastered with pink finishing plaster.
The wall looks like grey plaster / almost concrete like, but it doesn’t feel like concrete texture
We wanted to paint the walls - and just wondering whether it’s fine to paint on watered down emulsion, and then a coat of white paint on top.
What surface is the wall and is there anything I need to consider before painting the walls
