Finally got sick of all my allergies and ripped out the carpet in my bedroom. 3 big dogs. I thought it would be old tile underneath (the rest of the house is) but instead it is a concrete slab with a thin sheet of what I assume is a vapor barrier. 1960's house, might be a 1970's addition. The underpayment is glued to the concrete, and mostly but not completely intact. Bottom layer is black, top layer looks like linoleum. Has a kitschy photo pattern of shag carpet with little bits of baby blue and pink. Actually kind of cute, but I am wondering if it is asbestos based, if I need to cover it up fast for health reasons, if I can leave it there for a year until we tile or carpet, (will decide based on whether we sell it or rent it out.). Any suggestions? I don't mind the look, I just don't want the allergies anymore!
