The paint on some of my walls is "loose", you can peel it off in small
sheets. When you wipe your hand over the wall where the paint came off it
leaves a white powder on the hand. Do I need to seal the wall ? What should
I wash it with first and use to seal it? Any advice is very appreciated.

Seems they painted without a primer coat? Seal it with an oil primer.
