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...?
