I have recently purchased a house (in western oregon) built in 1909 that has many, many layers of wallpaper and wood paneling over plaster. So, I embarked on the mission of removing all of this until I have gotten down to the plaster walls. Needless to say this was a time consuming mission but I got there.
I want to paint this plaster. I am hoping to get some advice on what kind of primer to use on these old walls. I think it is worthwhile taking into consideration that these walls are over 100 years old and do have numerous hairline cracks and some minor damages to the walls that I will be fixing.
Am I better off using latex or oil based primer? Does anyone have any particular brands that have worked well for you on plaster of this vintage? How many coats of primer would you recommend?
