So it's not useless
The room isn't finished, but we needed to move the furniture around so the rest can be done. Here how they turned out
I went with Bostic MVP4 and Bostic Best adhesive. The floor guy said it was the best on the market.
The MVP is the concrete sealant. It was thick, kind of like epoxy. It took 5-6 hours to "dry". It was still tacky even 24 hours later.
Floor was glued down on Saturday. 2 days later, it feels really solid.
