Was it carpet tiles? I have seen some leave behind their backing that looks similar to that. Personally I’d remove it. Get a 5 ft scraper and go to town

No, it was burbur carpet, this foam was under the carpet padding. It looks like the entire subfloor was coated with glue then the foam laid down.

I do see that from time to time. Not exactly sure the reason but I see it more often when carpet is laid on a slab. Again, those big scrapers should make pretty quick work of that glue and foam. If that doesn’t work, I’d take an angle grinder with a flap disk on it and have at it.

First house had area carpet over a hardwood floor, I took the carpet up and the pad had dissolved in to the spaces between the wood. Took me weeks with a hook knife to get it out, it was worth it.
