Redoing wood floors found black glossy stuff under stove

Hey,

I had made a previous post about having the brown stuff under the plywood tested and it came back negative for asbestos. Great. Now i am almost done removing all the plywood and we came across this stuff underneath the stove.

It is pure black and was still glossy. at first i thought it was water but its not. Any idea what it is? Should i get this tested additionally?

It looks like tar. There could have been a leak long ago, and the only thing they could seal the wood and make it level was tar. We have self leveling compounds nowadays, but back then, probably not. Is it limited to under the stove, or does it stretch out further in the room?

Looks like tar to me also. Tar will dissolve with paint thinner, gas or kerosene. You might try a little on a small portion to see if it dissolves.

Maybe cut-back adhesive?

Hey guys,

Thanks for the responses.

I was afraid it was cutback also, but it seems to be painted on and not troweled. the rest of the floor had brown mastic on it that had no asbestos in detected.

The only thing i wonder, why would they put tar in a spot where the stove sits. Isn't tar a flammable material? I always told people my dinner parties were a blast... i just never thought they actually were.
