 underneath these 9x9 tiles that were hard. First off, if those were a linoleum-type tile or a vinyl asbestos tile, those tiles right there at 9x9 most of the time are going to be asbestos-filled. Not saying the 12x12s aren't, but 9x9s almost always were because those were a premium flooring. So that's a big one right there. That black mastic underneath, many times.
