Upon request, I’ve uploaded some pictures of the basement.  I’m traveling for work, so these were taken before I left.  I doubt Dad has done anything with it while I’ve been gone (he’s got his hands full with Daughter Person).

The “stuff” half of the basement

You can kind of see the really dark green/black spot next to the exercise bike – that’s where the glue is the thickest and most difficult to get up (so far).

Removed carpet (glue is still there)

These lighter areas are where the basement flooded previously, and I think it helped loosen up the glue, it was easier to pull up the carpet, and the glue isn’t as thick.

The “cat” corner. The carpet is gone, but the glue remains

Progress with the scraper after an hour

I scratched this little bit of glue off with my boot heel

I’ve acquired an angle grinder with a sandpaper disc, which works quite well at removing the thickest part of the glue, then we can scrape what’s left much easier.  We hit a snag before I left where we couldn’t get a face pin spanner to fit the grinder bolt to remove the old sand paper disc.  That part was not available locally, so hopefully, it has arrived when I return home later today, and we can keep going with the grinder.
