My house was built in the 70's and I started in the utility room to remove the linoleum, but found underneath old 12" tiles with the mastic under them, put on thick. My whole house is done that way. I used a chisel, hammer, scrapers, and anything I could find to remove it, with no such luck. Even the old tiles would hardly come up. I have been told that they rent a machine that removes this at the rental stores, but I have not checked. I just stopped, luckily I had just removed the linoleum in an inconspicous place. I was also told everything had to be removed right down to the concrete floor or the mastic would stain and make the new flooring uneven. I'm not so keen on using the chemicals unless I have to. Hope we find a solution.
