Originally, I just want to find what was the manufacture of old 8x8 tiles to exact match, then use same tile to fill a 10 sqft empty space which cabinets removed in the floor.

My bad is that I used Dremel to cut grout then used chisel to pull out 4-5 tiles, also grinding a few small oarts of black mastic parts to try to find some marks which may show manufacture info. Meanwhile, I used dry/wet vacuum to absorb dust.

Then I realize there is black mastic underneath the tile, which may be related to asbestos since house was built in 1968.Tiles seem like ceramic not asbestos. Just concerned about black mastic, is there any luck mastic is black but not asbestos? The previous owner disclosed there are asbestos tiles in some closets but didn't mention kitchen flooring.

I thought normally asbestos tile and black mastic should come together, does this mean previous owners have disturbed them and replaced them with ceramic but not removed adhesive?

If there are asbestos black mastic after lab test. Does this mean I disturbed them already? Do I need an airborne test?

    A:Don't Panic. Most actual health issues with asbestos are from chronic exposure, not a one-time careless mistake. B: given the age of the house, get the mastic tested, there's no way to tell "with or without asbestos" by eyeball. – Ecnerwal Mar 4 at 2:47

    Not an exact duplicate, but this should (hopefully) calm you down a bit: diy.stackexchange.com/questions/217202/… – manassehkatz-Moving 2 Codidact Mar 4 at 14:58
  • I’m voting to close this question because nobody can identify asbestos simply by looking at a picture. – FreeMan Mar 4 at 15:51

    Your best bet, especially if you're going to be pulling more up, is to get them tested for asbestos content. It'll cost you, but you'll know one way or the other. If they're not, then you've nothing to worry about at all. If they are, you'll probably want to have an asbestos abatement company remove the rest to minimize any additional spread. They can probably work in a deal on clean up from whatever minor mess you may have made so far. Anything else is just speculation. – FreeMan Mar 4 at 17:07
