Painting with calcimine


I have a large building with calcimine on walls and ceilings. Fortunately no one has put latex over it. Can I just recoat it with calcimine to avoid the difficulty of removal?

As long as nobody has painted over it then the Calcimine should just wash off the walls.

Like Matthew said you need to wash the surfaces first, removing the calcium. You shouldn't just paint over calcium. Calcium can occurs when there is a moisture issue. If there is a moisture issue that will have to be resolved before painting

Not Calcium, Calcimine. It's an old chalk type paint.

I tried to give him a heads up by PM. I think he blasted through a couple of threads and went to bed. I've never dealt with calcimine, that I know of, is it a regional thing? I did some reading on it today. Interesting.

Painting with calcimine


Ben Moore has an alkyd paint just for that purpose. Haven't had any experience with it, so I can't vouch for it except to say I've always had great results with all the BM products I've used.
And Zinsser Gardz is supposed to seal calcimine, but again I haven't used it for that particular purpose. I can tell you it's great for sealing after removing wallpaper, though.
And I've heard you can seal it with a penetrating oil based primer....but, once again....haven't done it...I'm being a big help, huh?

So, all that said, I'd remove it. But if you really don't want to, I'd suggest pick a product and try a small test area. Good luck!

js, you probably know it as "whitewash". Not regional that I know of, just old and often homegrown.

I have used both with sucess, but the BEST bet is to get it all washed off, oil prime and paint.

Painting with calcimine


I worked with whitewash thirty years ago in older homes in Philly, but my only experience is doing unfinished basement walls. Applied it with a big mason's brush. I've never seen it, to my memory, on finished plaster walls. Can only imagine what that's like. Thanks.
I found this article yesterday doing some research, found it interesting http://www.plasterlord.com/notebook/fcalcimine.htm

Reading the post fast I thought it said calcium. I have seen it on old plaster, especially after stripping off wall paper.

Lots of it in the real old farm houses. You really need to remove it for best results, it is not all that hard but it takes some elbow grease
