Our kitchen has an opening that used to have a bulky wood frame/shelves. We have removed that and now evaluating how best to repair the wall so it could be evenly painted and are thinking of adding a nice solid piece of varnished wood at the bottom.
The sides have a gap between the wall and the vertical opening. It looks quite large, too much to simply plaster over as it would probably just go and fall in.
What would be the best way to fix this? Would drywall tape and then plaster be enough? If I plaster, do I need anything special for plaster? I usually use the quick dry stuff to repair holes and have never done one that big.
Also, the yellow stuff seems to be only plaster, should I use what's there and add plaster to even it out/sand or am I better breaking what's there and starting over? I am not sure why there's a metal corner on one side and not the other.
