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.

Upper corner

Bottom corner



  • Are you familiar with the term cased opening?

I like the look of a cased opening with a bottom board incorporated to resemble a window sill on both sides

  • It's an opening like that yes. I am thinking of adding a board at the bottom, but would like to leave the sides/top as a "regular" wall corners / drywall+paint

    You need drywall corners in a few places, then. I'm personally fond of the metal corner/ paper covered ones, because you don't need to work so hard at getting them nailed up. If you choose to do a stool/apron at the bottom, just cover up the hole; otherwise, I'd cut more drywall away and install a bit of plywood as backing for totally new rock. (My suspicion is that most of what you have at the bottom has been broken up a little.) Commented Nov 25, 2018 at 23:47
