Back in the thirties, a lot of painters here used a chaulky kind of paint that was mixed on site with water and the powder. It leaves such a chaulky finish that most modern paints don’t stick to it. Painters here prefer to remove the plaster it is on and re-rock it or rock over it to get a good surface.
My question is whether anyone has experience with a method for getting paint to stick to it. I have a job with a couple of rooms that prrresent other problems with removing or covering the surface material.
I was thinking of something like having the painter scrub down the walls with a mild acid wash, rinse, and roll or spray a consolidant/bonding agent, then patch holes with durabond and new primer plus paint.
Excellence is its own reward!
