Heaven help me. This hot mess started because my wife wanted to paint this guest bathroom walls grey. One thing leads to another and I'm mightily frustrated trying to get this cement board up. Evidently drywall screwed randomly every few inches you can't access the screws because they are hidden by the layer of mastic that adhered the tile. Trying to drive my pry bar under it just causes it to crumble into pieces and takes forever. I've never used a demolition hammer. Will something small with a wide chisel break or cut through the drywall screws? I don't want to rent or buy if the screws are just going to ruin the chisels edge in short order. Open to other ideas to end this nightmare.
