I have a bath that I am helping out a little on. The existing wall paint has tiny bubbles where the existing paint did not adhere well to the under coat. I have no reason why that would and have no way to know what kind of paint the under color is.
Any of the painters out there have any suggestions to make it usable for a repaint? I was thinking about running a sander over the entire wall surface to smooth it as best as possible and prime/paint as normal.
I haven't seen anything like it before.
My hope is that the primer and paint will bridge the small pockets without to much trouble. I am trying to get her to pay someone to do a knock down to hide any problems but I think that isn't going to happen.
