Well I got all the wallpaper and glue off and damaged some of the drywall in the process - been there and done that in several rooms before. Thought I got it all repaired but now that I'm priming there are several spots where I didn't think I had to mud and now I guess the paper covering on the drywall was 'too thin'? In these spots there is 'puckering'. What to do - wait for it to dry, score with a knife and remove the paper and repair again with drywall mud?

I have a one story ranch house. The house has a half-finished basement. There is a set of stairs that lead down into the basement. I want to paint the basement. I don't know how I can paint the walls and ceiling surrounding the stairs. The ceilings on the first floor are 8 feet tall, and there is the additional space created by the stairs to deal with as well. I don't think a roller with an extension will reach all of the wall and ceiling areas. Also, I am concerned about only having a thin stair to rely on while I painting these areas. I attached a rough drawing of the stairwell. I am not sure how sturdy the platform at the end of stairwell is. It is covered with paneling that I am planning to paint over. I am not sure if it is sturdy enough to support a makeshift scaffolding. It kind of makes me anxious to use a scaffold in this area. Can you give me an idea about how to safely paint a stairway space. Thank you.
