Many years ago I had a wall replastered and the job was terrible. As I was working at the time I just painted over the lumpy and dips in the wall. I now have time and have sanded the wall. The problem is that I have obviously sanded of the plaster and the initial coat of paint in a number of areas.
I am now unable to fill the small areas (as they are only as thick as two coats of paint) where I have rubbed back to the plaster and the new paint does not cover the damaged areas.
Any ideas on how to make good?
