In my basement I removed old carpet planning to install LVP, so I need to flatten out the slab a bit. The carpet left a thin glue residue over the entire floor that I've been trying to remove before pouring self leveling cement (pictured below).
It's still tacky with enough weight, but otherwise dry. I've tried to scrape it off, but can't really make any head way. I've tried boiling water, a heat gun, and a couple solvents but all failed to loosen it much. The only thing that has worked is a cup wheel concrete grinder, but it gets gummed up really quickly.
So my question is, if this adhesive is so hard to remove from the concrete that I need to take some concrete with it, can I just use the self leveling primer over it and then pour like you would for concrete with well-adhered paint? What would be the possible consequences of not removing it?
