Wish I would have asked someone prior to putting my new flooring down. There was a small area of old vinyl sheet that I smoothed out with a belt sander along the two ends. This was after trying to scrape it from the floor and decided best to just go over it. Now I understand that it may have contained asbestos. These areas were about 48" long by 6" wide each. It did create dust and now.......after the fact I have no idea what to do. Recommendations please.
House was built in '74 - '75. No idea how old the floor is but may have been original.
