Sweet Calcimine

Ah, the joys of an old house.

B and I began a rather large project over the weekend. Our living room ceiling had a series of cracks that had begun to alarm me-visions of massive chunks of old horsehair plaster falling on my children's heads began consuming my every waking thought-so I did my research and came up with two possible fixes. The first option was to tear out the entire ceiling and install new drywall, the second was to try and repair the plaster using Big Wally's Plaster Magic (sounds awesome, right?). This second option would allow us to re-glue the plaster to the lathe using a super special adhesive without removing any of the original plaster-so I decided that Big Wally's it was.

The first day consisted of drilling a bunch of holes into the ceiling, shooting them full of goo and screwing temporary supports into the lathe until the adhesive fixed. This was surprisingly easy-very little mess, very little hassle, just a lot of time.

Second day consisted of the same, but done with a slight hangover (unrelated to the project itself).

The third day I rested.

Today is the fourth day and time to remove the temporary supports. No problem, no worries, that is until I attempt to scrape the excess glue from the ceiling and discover that the paint is coming off the ceiling in sheets, big sheets and little flakes.

I'm alarmed, I keep scraping, the paint just keeps coming off, I'm even more alarmed...I run to my computer and do a Google search.

Here's the issue: In the olden days, when this house was built, after the walls were plastered it took between 6 months and a year for the plaster to cure. Walls and ceilings couldn't be painted until the plaster cured; clearly this was too long to wait and so Calcimine was applied over the uncured plaster. But what in the hell is Calcimine? Calcimine is a water-base paint containing zinc oxide and glue and coloring (I don't know this to be a fact, I got this info online).

This is all fine and well, but it seems that nothing will bond with the Calcimine except more Calcimine, which is sort of like liquid chalk dust, not really permanent (remember all those Laura Ingalls Wilder/Huck Finn-type stories where everyone was always whitewashing the house or the barn or whatever the hell it was they lived in? Same concept). Of course, eventually modern people painted over this crap with latex or oil based paints. On a ceiling it isn't such a problem unless you get moisture between the Calcimine and the paint or you start scraping at the paint as I did, and then you will find yourself in the state of mind I currently find myself in...pissed off.


The only way to properly address this issue is to wash all this crap off the ceiling, wash again, and repeat and repeat and repeat. Then let the ceiling dry. Then skimcoat the areas you damaged while scraping. Then let that dry. Then skimcoat again. Then let that dry. Then sand. Then prime. Then paint.

Wait, did I mention that this is in the living room? Where we live?

Or I could just pretend that I didn't know better and paint over it directly.

Hmm.
