Going to tear up the carpet/pad and put in hardwood. Carpet comes up easy. The pad however has been glued down and it isn't your normal pad. It's the same thickness (give or take) but more like moderately dense foam. Trying to pull it up just results in ripping off a little bit, leaving some of it glued to the floor. I've done a little bit of it with various chisel/spatulas and it's a nightmare process.
Doing it the way I have been would take weeks and right now I'm seriously tempted to just tear up the sub floor and replace it too.
The DIYer in me thinks there must be some sort of solvent I can pour over the whole floor or some sort of hard-wire-brush-on-a-floor-sander attachment that can just tear it off.
Wondering if anyone has any suggestions? There has to be something...
UPDATE: I ended up buying a Spyder Scraper for my sawsall on the off chance it would work and it worked amazingly well. Like shearing a sheep easy. Kept the sawsall angle low to the floor and it removed the padding quick and easy. Occasionally I'd hit a nail or edge and ruin a blade, but only went through 3. Totally worth it. Removed 4-500 sq ft in about 30 minutes.
