Carpet Glue removal from Aggregate concrete

I have just removed outdoor carpet from a screen porch. The floor is aggregate concrete and there is a white band of compound on the edges where the carpet was glued. I can not use a scrape, adhesive remover does not work and a pressure washer does not work. Sandblashing is not an option.

Any suggestions on how to remove the compound?

So, basically there are no options left.......unless you want to get a sander or 4" angle grinder.

why can you not use a scraper, Health reasons?
have you tried a heat gun.? if you can not use that then sanding is about the only option.

I was going to suggest a bead blaster, designed just for such a case of removal over a rough substrate.

Ask your local carpet supply store for recommendations on carpet mastic removal. There are solvents that you can apply that will break down the glue. You should be able to at least pressure wash the softened glue away after the fact. If they are unsuccessful, get the phone number of some carpet installers, they will have access to supply houses that sell the specific solvent that is needed.

I'll assume that since you posted this on the tile forum that you will be installing ceramic tile or stone. If that is the case, you need to remove the adhesive mechanically as solvents may affect the thinset bond to the slab. If you arent installing tile well then nevermind.
