We have a half wall that divides the dining room from the steps leading down to the basement. The problem is that on the corner of the wall (which is rounded), the paint has peeled off in large chunks exposing what looks to be plastic underneath. Is it plastic? Would the entire wall be constructed of this? What can I use to patch this up? And, for my future reference, is there an easy way to maybe even cap off the wall with a nice looking wooden cap or something?
Thanks!
