Hi All,
Redoing a house. I started in the bedrooms by patching and filling holes prior to painting. While working on the walls, the old paint (about 15 years old) would "wrinkle" where I was working. I worked a trowel under the old latex paint layer and I can just peel the paint off the wall - almost zero adhesion.
The original wall surface has a chalky-like quality to it. What can I do to prep these walls for proper paint adhesion? Perhaps a TSP wash?
Any pointers really appreciated.....
Greg
