Ceiling discoloration


Last winter I had some water intrusion and it stained part of the ceiling as shown. It’s covered with this funky popcorn stuff on it.

My question is: can I just scrape off the popcorn, seal and prime and paint; or would it be better to take out the ceiling and put in new drywall?

Also I’m planning on replacing those light fixtures with one ceiling fan in between them.

Thanks to y’all for your thoughts.

Re: Ceiling discoloration


An oil base primer [use pigmented shellac if really bad] will seal the stain so you can successfully paint over it. Whether or not to replace the drywall is dependent on how solid the drywall is and if you suspect any mold on the reverse side. If you want to put in a ceiling fan you'd probably need to remove drywall in order to install a fan box.

Thanks for your prompt response!

I’m pretty sure it isn’t drywall but that funky old fashioned plaster stucco stuff with wire netting in it. It’s cold to the touch unlike drywall that’s closer to room temperature. It appears to be in reasonably good condition.

Other parts of the house had much worse damage requiring removal of the ceiling including a “lower living room” about 20 by 25 feet. That funky stucco was masochism to remove and dispose of. I’d like to avoid having to more of that than necessary.

Re: Ceiling discoloration


Insulation? mold? attic access?

This house has a funky attic that's much too small to get around in easily.

I know there's insulation. As for mold, not sure.

You will want to change the box to support the fan, then you will be able to inspect at least a hand full of insulation, I guess. So I would do that before painting, you can still use the light after that if you want.

And, if need be, install more?

If was me I would be tempted just replace it all with new sheetrock. Open it up to attic to double check insulation. If need be add some more insulation. New electric boxes as well. That is a expensive option.

The other less costly option has been mention. Scrape and a good primer then paint.

The easiest thing to do is stain block it, and paint it. You can scrape it, but based on what you said it's not going to get smooth, just a different texture. I wouldn't do all that work for just a different texture. For more work you could scrape it, then skim coat it and sand it to get it smooth.
