I had a leak this past week that came down through my kitchen ceiling. When I opened it up, I noticed this weird first plastic like layer over a sand based material.Here is a link to the image: https://ift.tt/2EYCOjt am trying to figure out how to even repair this stuff or does this need to be taken out and new drywall go up over it?For a bit of background, this house was built in the 1950s in Ohio.Thanks for the help. via /r/DIY https://ift.tt/2CZr2mt
