My husband uses an electric wheelchair and has damaged some of our walls by not taking care on his turns. I would like to put something on the lower part of the walls that is indestructible while blending into our decor. We have one particular spot that is the entrance to our kitchen (about 18 inch deep passageway).The skim coat seems to be scracthed off down to the wire mesh beneath it. Is there a material that could be used other than a plexiglass panel? Could a piece of formica work? All suggestions, other than getting rid of the husband, are welcomed.
