I'm trying to rehab and old plaster ceiling from a 1940s apartment in Manhattan. I have scraped off most of the plaster and much of the old patch work but a lot of the patches and more recent work is impossible to get off the ceiling. There are no more flaking pieces of the ceiling so I am ready to move on to the next step.
I don't need to remake the ceiling in a perfect manner as the walls are not in great shape either. I am looking to do a decent job and one that will cover up most of the problems and the ceiling. I was hoping that someone could start to describe different products and how to go about starting off. I understand that I have to fill the gaps and gouges, maybe an intermediate coat then possibly some real plaster to finish it off but I don't know the actual product names or order in which I should start these repairs due to conflicting opinions.
