How do I repair or replace popcorn ceiling?

This is likely happening because of the moisture. Before repairing it make sure you have good air flow like a ceiling fan or a window to crack letting moisture out.

It's a total NIGHTMARE-- that crap is blown on wet, then sealed, painted etc. To scrape/clean it off and resurface is major work ... needs to be professionally done. To replace by remudding & smooth coating then painting the surface is easier, cheaper, faster in the long run. Just GET RID OF IT-- resurface with new whatever, then you can paint/repaint anytime you choose!

I would get it scraped off and put a new texture on the ceiling. Popcorn ceilings reduce the resell value of a home.

We repaired our popcorn ceiling from a kit that comes in a bucket from the home. We had never done it before and you could not tell where we did the repairs when it was done. The supplies and instructions were easy to both fix and follow. See your local home improvement store and find what you need there for your ceiling. If you decide to repair it, you would need to cover everything and scrape it off. It is hard work but not difficult to do. Our neighbors scraped theirs off and duct taped a vacuum hose to the scraper to save much of the mess. I wish we had thought of it. When we scraped it off, the ceiling still had a flat but textured surface and we painted it with a roller. It was beautiful. Good luck, Robin and hope this helps.

Hi. Popcorn is thick plaster. You can scrape it off by spraying with hot water and scraping it off with a putty knife. It's a messy job, but can be done. Once you've gotten it off, you can then repaint the drywall. Happy DIY'ing!

Thank you all so much for the info. The entire house has popcorn ceilings... this spring we will start with the smallest, most problematic area, and start the removal process!
