Can't Cover Ceiling Paint

My house was built in the 50s and I'm repairing my kitchen ceiling (small holes) and repainting. I experienced water stains from ice dams a few years ago and actually drilled a few holes to relieve water.

The ceiling board surface itself is darkish and has a fabric glued or embedded to the surface, then coated so you don't see the fabric. It was previously painted white. It still looks whitish but appears dirty after all these years. We mixed up a batch of TSP and wiped down the ceiling, with a small amount of clean water wiping afterwards.

I put one coat of KillZ w primer on it and two coats of latex Behr Ceiling Paint and it is not covering the old surface. In the morning light today you can go around and see light brownish areas where the paint did not cover, 50% of the area. My son who did the painting said he could see the Behr paint repel itself away from these brownish areas.

I don't think it is calcimine, (not chalky). But looking to make it look nice without anything major needed. Help! and thanks.

I'm wondering if I need an oilbased Kill Z...?

Re: Can't Cover Ceiling Paint


I suspect you used Kilz 2, water based primer, rather than The Original Kilz, which is a quick dry oil primer. Those brown water stains are water soluble. If you use a water based stain, the stain will leach on through. An oil primer, such as Original Kilz or Cover Stain, will block this leaching. Then finishing with a coat of water based acrylic paint is fine.

Most ceiling paints are not particularly suited for kitchen ceilings. They are too porous for high humidity and stain prone areas. However, the Behr Ultra Ceiling Paint or the Marquee Ceiling Paint are much more washable and stain resistant. Avoid the Behr #588 Ceiling paint in a kitchen.

Great advice, thanks for the paint tips!
