Paper backing on vinyl - please help
I had posted before of old 1950-60 vinyl. I had it tested and adhesive underneath.
I hadn’t pulled up the covering new vinyl a lot so 8 samples were taken around corners of the adhesive and vinyl.
No asbestos found
However when removing I found paper backing. Which online I read can be the dangerous part? This wasn’t present in other areas where tested
Is this a concern?
