VAT floor tiles?
 
I'm worried I have VAT floor tiles. They're from a late 1960s home, their 9x9 and they are glued down with black tar like glue.

But they aren't hard like a tile. In fact, they're more like a vinyl tile in that they peal and can bend easily. Any thoughts?

Cork tiles---however the black 'cut back' adhesive may contain asbestos----

Asbestos only becomes a concern when is a powdered form and becomes airborne---

What are you planning to do and why are you concerned?

I plan on putting engineered hard wood over it.

But now I'm thinking about putting a layer of self levelling concrete over it first.

Edit: I'm not sure it's cork. Like I said, they're soft and bendable like vinyl.

Very likely--If you post a picture one of the older installers might recognize it--

If you wish to use self leveling compound be sure to prime it---read the directions on your leveler---

Jifset ,for instance, gets mixed with a liquid latex and does not require priming---read the directions---

Very likely cork or vinyl?

Here is what the tiles look like. They're quite thin.

And this is the black tar underneath - this was actually from another room with carpet.

Little late now but that old tile could have acted like your vaper barrier and an engineered floor could have just been floated over it.
Now you have exposed the dangerist stuff under the tile.
To remove it safely your going to need a product like this.

The black stuff was under a carpet in another room.

The tiles are still down in one room though.

Engineered HW is going in both rooms.

If the tiles are down solid, just install over them like you would any other subfloor.

But should I seal it with a concrete paint, stain, epoxy or anything? The whole possibility of asbestos thing has me somewhat anxious

I plan on using this too:

There's 0 danger if you floor right over it with the underlayment or vaper barrier.
By trying to remove it you now exposed it and caused a possible danger.

One room is tile with carpet laid over it (the first photo with the red carpet). The title is still there and it's in good shape.

Another room had old carpet glued to the concrete basement floor (the second photo). We pulled the carpet, but haven't scraped the floor.

The tile and the adhesive both probably contain asbestos. But they are completely safe as long as they aren't disturbed and it is not hard to remove it safely either. In the early 80's, the EPA told flooring installers to just cover it whenever we could.

RCGA 03-30-2013 03:22 PM

What did you cover it with?

joecaption 03-30-2013 05:17 PM

New flooring, there was no good reason to remove it unless you were going to tile it.
Some how I think your missing the point. Undisturbed it's harmless, once it's removed, sanded, cut, chipped it becomes air borne and becomes a danger.
It does not need to be sealed, just covered over.

RCGA 04-01-2013 12:40 PM

Well as of right now I plan on using concrete sealer and then an underlayment on both the room with the tiles and the room with just the mastic left.

The biggest problem is that the more I read online, the more I become neurotic about the whole asbestos thing.
