Removing glue from cement

Q: I’ve recently ripped up engineered hardwood that was glued to plywood. We also ripped up the plywood (there was so much glue it pretty much came up with the hardwood). The plywood was also glued and screwed into the cement. We’ve gotten most up but are having issues with the remaining glue.

There are some spots with wood still stuck to the glue and we cannot get it up! we’ve tried glue gone, scrapping, paint thinner and hot water and these small spots of gluey wood don’t seem to budge! Any suggestions?

A: Bostik does make an adhesive remover that would likely soften it. You could also rent a machine to help chop up the remaining ply and adhesive. It’s a nasty job.
