I am working on a vinyl floor solution for a veterinary hospital. The present floor is what I believe is IVC's best residential sheet vinyl from around years ago over 1/4" underlayment all over the original sheet vinyl. The present vinyl is a textured wood visual that is difficult to get clean. Can we level emboss the existing and go over with Corlon or similar sheet vinyl or should we add another layer of underlayment. The existing floor seems to be well adhered.
