I'll admit, I'm definitely a novice when it comes to finishing drywall. I've done loads of patching, which doesn't typically require working with corners. This time, however, I'm doing a whole room.
I watched some YouTube videos, and read a few articles online about how to properly finish inside corners. Everybody makes it look so simple, but I just can't seem to get the hang of it.
The process goes something like this...
- Put some drywall compound on each side of the corner.
- Fold the paper tape in half.
- Press the tape into the mud.
- Place a corner trowel in the corner, and with gentle pressure on the back of the trowel draw it down (or up) the corner.
The first problem I was running into, was that instead of the trowel sliding along the tape. The tape was being pushed along by the trowel, and it would bunch up and be removed from the corner. I solved this by pressing a bit more gently, and holding the tape in place just to get started.
The next problem I ran into, was that while I slide the trowel down the corner, the tape would ripple and bunch up ahead of the trowel. To fix this, I had to use my taping knife to smooth the wrinkles out of the tape. While this worked in the long run, it seems less than ideal. This extra step was never mentioned in any of the videos or articles, which made me wonder what I was doing wrong.
Am I adding too much (or not enough) compound to the corner? Applying too much pressure with the trowel? Or do I just need to work on my technique?
