1- What makes paint peel?

Paint is designed to stick to the surface being painted. If you have peeling paint then there are usually some fundamental issues with the adhesion of the paint. The most common issues of peeling paint are moisture, dusty/unclean surfaces, incompatible products, temperature and smoothness of the painted surface. Calcimine ceilings peel because of incompatible products being applied over it.

2- Where ceilings do commonly peel

The most common room for ceiling paint to peel is the bathroom. The excess moisture from taking showers along with contaminants from soap, cleaners and beauty products can be a cause. Calcimine coated ceilings have a tendency to peel when painted over with incompatible coatings such as latex or acrylic ceiling paint.

3- What is calcimine paint?

Calcimine paint was used in the past up until about the 1940’s and still found in some houses into the 60’s. Calcimine paint was an easy and cheap coating to give interior surfaces a clean look. Calcimine was made from easy to acquire products like calcium carbonate mixed with water (sometimes pigments and glue) to make an easy to use and fast-drying coating for walls and ceilings. These were the days of heating with coal and wood stoves, so walls and ceilings stained with soot quickly and calcimine was a quick and inexpensive cover-up during spring cleaning. source: read more here

4- What is the problem with calcimine?

If you continued to use calcimine you’d have less problems with peeling, however, technology and coatings have evolved. Old school- since calcimine paint was applied with water, and the calcium carbonate is soft, it poses a long-term problem for homeowners when applying current latex or acrylic paints over calcimine. Acrylic paint is water-based it will reactivate the calcimine, which is chalky, and peel off, chip, or have bubbled paint on ceiling.

6- Scraping the loose paint

Whether you have paint peeling off the ceiling while painting, paint peeling from ceiling or paint cracking you’ll need to scrape ALL the loose paint from the ceiling. Sometimes a small cracked or peeling area will scrape off exposing a larger area than it looked like. Scrape the loose paint until you get to an area where the ceiling paint is tightly bonded. Wiping or cleaning any excess chalkiness will greatly help.

7- Spot priming

After all the areas of failed paint are scraped it’s time to spot prime. Remember that calcimine is loosened by water or moisture. You will want to apply a moisture-resistant primer. In this case, you should use an oil-based primer so you do not reactivate the calcimine and keep paint from peeling.

8- Patching

After the primer has dried it’s time to patch all the defects. Use your patching compound of choice and apply the number of coats needed to make smooth after sanding. Patching compounds are water-based so be sure to patch only where the oil-based primer was applied so as to not have issues with the moisture from the patching compounds over calcimine. Allow to dry and sand smooth.

9- Spot prime again

Yes, another coat of oil primer should be applied over the patches. This ensures uniformity of the finish coat by sealing the porous filler.
