I recently pulled the very old linoleum up from my dining room floor. The hard wood below is beautiful, and I want to refurbish it. Most of the linoleum is up, but some areas had lots of glue and have the bottom of the linoleum still attached. I have spent many hours with a putty knife trying to get it up. Is there a better way to get this stuff off? This is my first attempt at a project like this, please HELP.
