I need to close up a window hole (that was on a formerly exterior wall and after an addition, turned into shelving).
Apparently plaster veneer is unknown in my parts, but it'd be a perfect solution to match the existing rock lack/plaster the rest of the walls have.
What should I look at for alternatives? I have a little experience drywall mudding, but far from a pro. (This patch is pretty well hidden so results don't need to be perfect.)
