I'm trying to remove tar paper from a pine floor. What are the odds this stuff contains asbestos? Sanding appears to be the easiest way to remove, but the dust concerns me. This floor installation dates from about 1960.
Most likely lining felt. Was usually put down with linoleum paste. May have some luck by scoring with a utility knife and soaking with water with dish detergent added. score all over so water can reach the paste
