I’m trying to repaint Circa 1938 (new england) interior walls and ceilings which are made of an extremely smooth plaster which has been described to me as "Calcamite" (Spelling uncertain?)

Our walls aren’t gypsum wallboard (dry wall) nor are they horsehair plaster so I’m unclear what they are?

Older layers of paint still on these walls and ceilings have notable pockets or bubbles where the old paint is falling away from the wall surface.

Does anyone know of this material (Calcamite), and have experience dealing w/ this wall surface, and how to prep it for painting?

Any advice would be appreciated.

Calcimite paint is a tricky one... we had it on the ceilings. You need to get it completely off of the wall/ceiling before you repaint or the paint will flake off. Which is what you are experiencing now. There are many ways which to do this, wall paper steamer (you may notice more falling flakes on sticky days in the summer), scrape off, scraper or I've heard of using a stake knife. Its a long ardjous task, do small sections at at time. When you are all done wash well with TSP and coat with a paint made for covering calcimite. Do a good web search for other boards on old house restoration. I cannot remember the name of the paint and its not something available in most box stores or the local paint store... and I'm quite certain suggesting the name of the board would be forbidden... good luck!

I had a similiar problem with my ceiling, my house was built in 1860. People were reccommending I drywall over the celiing, but I didn't want to lose the height. I ended up going through with the arduous task of removing as much paint as possible. Then I used a product called calci-kill. I got it at Home Depot. Then, to make the ceiling smooth again, I mudded the spots that were uneven.

The whole process, for one ceiling, took about a week of working 3-4 hours per night. It wasn't bad, I'm going to do the other ceiling on the third floor the same way.

Good luck.
