Hi James,
I have serious doubts that cork was applied by Piper; It’s heavy and to my knowledge rarely used to absorb sound. A previous owner must have installed it.
I suggest you head over to your local hardware store to get some acetone, a putty knife with a 3 inch wide blade, a fiber bladed scraper, some one edged razor blades and some nitrile gloves. I doubt that you’ll be able to peel it up like the skin off an orange so I would scrape as much off as you can. Then take a rag and, covering the remainder wet it with the acetone.
Let it soak for 15 or 20 minutes, then see if you can scrape the glue off the floor surfaces. It’s also OK to use a small wire brush but only if it has stainless steel hairs.
It’ll probably be slow moving, make sure to not spend to much time breathing in the acetone fumes.
Let me know hot it comes out.
Steve
