If the adhesive is removed from concrete before it has cured, an acid-based etch remover (such as hydrochloric acid) is typically used to remove the surface of the adhesive. If removing cured adhesive, a sealer over top of the old layer will need to be applied in order for it to have any level of success. Buffing with an abrasive pad will also work with some types of surfaces, but not all. You can also try scrubbing or pouring on boiling water which should soften up the old layer and allow for easier peeling as well.
