I'm in removing corkboard tiles from a plaster wall. Removing the
tiles has been difficult--they were nailed plus glued to the walls--
but now I'm at the worst point, trying to remove residual bits
of tile and the glue. I've been scraping the wall, but it's taking
forever. (The wall is about 12 feet long by 8 feet high.)

Does anyone have any suggestions? Are there solvents that would
do the job more quickly?
