About 30 or so years ago my in laws put vinyl tile over a red oak floor. At the time I don't think they did drugs . They are both gone now and we want to restore the oak floor. The black stuff looks like tar paper but there are lines in it like it was some kind of mastic. What does anyone recommend to soften this stuff? Does anyone remember an adhesive like this? I have about 120 sq Ft to get this stuff off of.
Thanks for any suggestions1
