We are remodeling our offices at work and we are polishing the concrete floors in all the common areas. We had no problems on our second floor as the concrete was good under the carpet. However, on the first floor, we are finding Burlap glued down to the concrete under the carpet and we can't get it removed. We tried to grind it off and it just gummed up the grinders and made a big mess. We are looking for an adhesive remover that is low or no-odor if possible as we are still occupying the office during construction.
