Asbestos in floor apt built 1959

[Jesper Henttonen]

Tore up an old floor down to the slab in a small kitchen. Could this be asbestos, or do you recommend sending a piece for testing?

What are you going to do with the floor?

 

[Jesper Henttonen]

I'm going to lay new flooring over it. But it's a bit uneven, so I would prefer to remove that.

Self-level and then lay the new floor.

Looks like brown paper but could still be asbestos in the glue. I had something similar that didn't contain asbestos, but to be sure, you'll have to have it analyzed.

Looks like fiberboard but there could still be asbestos in the glue. I had something similar, it didn't contain asbestos, but to be sure, you need to have it analyzed.

Could be asbestos in the fiberboard too if I'm not completely mistaken.

It looks like there is suspicious black adhesive under the actual felt paper. That sets off some alarm bells. Asbestos was also present in lighter types of contact adhesives. Relatively bound in the material regardless. The felt paper itself I believe is very unlikely to have had asbestos in it. As the name suggests, it consists of pressed felt, used to prevent squeaking and leveling of the substrate.

More interesting is how did the floor mat look that you tore out? There are many mats that contain asbestos as a component or have asbestos board underneath as reinforcement.
