I am attempting to improve the kitchen on a 100+ year home. Someone put plastic tile over beautiful wainscotting. I would like to remove the old tile and install new wainscotting over the existing wainscotting which is beyond repair. Does anyone have any suggestions on how to approach this? Do I really need to remove the old tile adhesive? Should I just cover the existing wainscotting with new wallboard and start over? Help!!!
