I pulled up some vinyl tile in my bathroom while redoing it, and it as well as the subfloor underneath had some black tarry residue on it. I did some research and found that it is possible that some vinyl flooring as well as the adhesives used could contain asbestos. I ripped off a piece of the tile to have it examined and sealed the spot the best I could, but I was curious is anyone here is familiar with the risks involved or has run into a similar situation. My house was built in 1979. The tiles are 12in x 12in, are very thin and brittle, and have a decorative pattern on them. The adhesive used appears to be black in color and somewhat sticky. I know that there was a ban enacted to stop the use of asbestos in building materials in the late 70's. Any advice would be appreciated, as I'm a novice at working with this kind of stuff
We had the same sort of problem in our 1964 house. I had the OSHA guy look at it and he said it probably was asbestos. So were didn't remove it. We covered it with Hardibacker and put down tile. Problem gone. Otherwise it may cost $3000-$5000 to have a pro remove it as seen on This Old House this season.
