While repairing several popped beads at the base of bullnose corners, I ran into a problem with at the interior corner of a perimeter wall. I messed up and scraped it out expecting to find corner bead and only found the corner of the base sill and I guess has to be a stud. See the picture.



The good part is if I don't go any higher, the repair will be covered over by tall base board. Just mudding it up with several layers of joint compound doesn't seem right, as it will likely crack or fall away from its weight in time. The consistence of what I took out seemed more like it was drywall and not mud. I can neatly widen the area and square it off so it will accept some new dry wall and then mud it up with a thin layer of j/c,

Thanks.

 

If it will be covered by the base, I'd just rough fill/shape it with a setting compound. It should adhere ok and the base will keep it from going anywhere if it doesn't.

 

Thanks. I picked up on the fact that you said you would use "setting" compound so I googled and immediately see the difference with the all purpose joint compound that I first tried.

 

I probably should have mentioned the 2 most popular brands, Durabond and EasySand both come in different set times with the most common being 90 minute, 45 minute or 20 minute.

 

Again, thanks. Using the right material makes any job a lot better.
