How To Remove Carpet Glue From Concrete

Remove old carpet. We were able to just pull ours up. It was laid next to the baseboards. We used a utility knife to cut it into sections and rolled it up.
Add painter’s tape to the baseboards.

Use a little elbow grease with a hand scraper tool to do a dry scrape of the glue.
Use a shop vac to remove the particles from the floor.
Add adhesive remover to the floor and spread it around.
Cover the area with plastic.
Let the glue remover rest for 1-3 hours. Test to see how easily it will scrape off.
Using your hand-scraping tools continue to work to get the glue off the concrete.
Use a mop and soapy water or a sponge to get rid of glue residue.
Repeat the above steps for stubborn areas.

This DIY does require some elbow grease. Let the glue remover work for you and don't try to rush the process.
Carpet glue adhesive remover could be slippery when stepped on and you also don’t want to track it around your home.
The recommendations on the glue remover said to use a thick plastic drop cloth. However, a plastic garbage bag worked just fine for our concrete floor.
2 hours under plastic seemed to be our sweet spot where the adhesive remover was working without drying out.
Don't let the glue remover and glue begin to dry when you have removed it.
