Removing drywall that's glued to concrete

Wonderbar is probably the best bet on removing the glued drywall.

Leaving some drywall glued to the concrete would be a recipe for mold. There is no way to determine if there is a water barrier between the existing drywall and the concrete wall, which I would suspect there isn't.

Remove all the drywall, waterproof the concrete and then add framing and insulation. If you're spending the time to do a complete refinish, that's the best way to prevent future issues.

If you don't repair the water invasion from the outside you are wasting your time and money.

Obviously you need to get the sections of drywall out of the way. I have a Fein multi tool I paid a fortune for years ago that turns tasks like getting rid of glue on concrete into fun amusement park rides. I should think if you don't want to spend $500 or whatever the Harbor Freight, Craftsman, Rockwell, Dremel et al versions would work for getting the glue out of the way as well.

By the way, of all my tools, justifying the cost of the Fein thing has been among the easiest. I used it almost every day for something when working. And it was a major time saver which pleased my clients.

I think the production brands mentioned are all under or just over $100? Find one that is nicely balanced, is not too heavy, and does not overheat or vibrate and you too will find you reach for it as a fave go to tool. You can get generic blades now too which will be just fine for getting rid of construction adhesive once between drywall and concrete.

If you have a compressor and a pneumatic hammer, you can can use that. They have some wide chisels that will make the job go faster then a pry bar.

I fixed the outside water issue already. What's going to be an issue is it's about 60 feet of wall 8 feet high that I need to remove drywall from...

I picked up a heavy duty floor scraper today. I guess I'll give that a shot.

edco makes a pneumatic chipper called an ' ugly stick '- much easier to use,,, among its tools is a thin scraper about 6" wide,,, if you can't locate OR make 1 using an air/chisel, try an elec chipping gun - good luck !
