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.
Any comments?

Calcimine?
maybe. As I understand it, Muereusco was a product name back then. Is calcimine a catagory or product name?.

http://freepages.history.rootsweb.com/~mchub/carteret/benmoore.htm A little bit of history about Muresco.
Try covering it with MOORCRAFT SUPER SPEC ALKYD CALCIMINE RECOATER. I think Muresco is calcimine, but not sure. I'm not even sure how to tell if you're looking at calcimine. I think calcimine may be an urban legend, everybody talks about it, but how many times do you paint over something that was last sold 80 years ago or so?

OK, I'm certain Muresco is calcimine now. Chalk and glue with some color. Does not hold paint because of the softness and surface tension of the glue. Here is some more reading material.

Thanks for the direction. Those guys at Lord and Plaster are right down the coast from here and that was a very informative site. Another site I came across says that it is made mostly from Irish moss and Pennsylvannia clay. Since clay and chaulk are both alkaline, the acid wash idea probably has merit and the lead for the right overvcoat product sounds good.
I really appreciate it all..

If everything seems to be going well, you've obviously overlooked something.

is something else that you can use on calcimine ceilings. I usually scrub it off as described in a previous post. That and Loxon or the Bennie Moore product should give you good results. The scrubbing is nasty work.
