How to remove ceiling tiles that are glued to drywall?

Yikes! All you can do is try to pry off and chip away with a wide putty knife. I have a feeling they did that to cover up damage. Don't be surprised that between trying to remove the tiles and what s up there, you'll have to replace the ceiling. Sorry you have to go thru that.

Hi Doris! There are tons of videos out there. I watched one, but, then remembered how we removed mirror tiles from drywall about 30 years ago, when we bought our old house and thought that might be more helpful. They had been attached with contact cement so we pried them off, one at a time, trying not to break them (I didn't want to be cleaning up broken glass everywhere or get cut). I used metal scrapers and a utility knife that held razor blades and removed as much as I could of the glue, without cutting the drywall. Then I used a steamer (I used a wallpaper steamer) to soften the remaining glue. You may find the sheetrock wasn't finished before the tiles were applied, but, that's okay because you can fix it. It can be messy, so wear protective clothing and protect the floor with a dropcloth. Take your time and be careful.

A scraper and lots of patience. Assuming the tile was attached using dabs of adhesive there isn't any easy way to remove without causing damage to the drywall facing. After removing the tile and glue you will likely have to repair the drywall board either by skim coating with compound or adding a new layer of wall board. Drywall does come in sheets thinner than the standard 1/2 inch, but, these are usually more expensive. If adding new board make sure to locate the ceiling joists and use longer screws. Good luck.

Excellent advice Kelli. I would add that removing it will also remove the paper from the face of the drywall. This will make it necessary to replace the drywall.
