Issue with removoing paint - maybe oil under latex, plaster walls
Long time listener, first time caller.
So, I knew that they previous owners had painted latex paint over oil on the trim. I've been working on removing in using various methods, some more successful that others.
Now, the real issue came in when I accidentally bumped the wall nearby, which I had recently primed. Much to my surprise the paint just peeled off. I know I'm not necessarily doing things in the proper order but I'm a newbie. So, I started scraping the walls. It's going well on one wall. On the adjoining wall the paint is coming off quite easily but has peeled down to the plaster in some places.
I'm really at a loss as to how to proceed. I figure I'll scrape as much as possible. The issue is that the old paint is adhering to the plaster in some places but not in others. With further prodding it comes off down to the plaster easily but in other areas it's really adhering.
Do I need to get it down to plaster on the whole wall? Should I think of skim coating it? If it's part old paint and plaster is there a solution? Any and all advice is welcome.
