Inside Corners / Outside Corners

After putting up the new drywall in our kitchen, we had to form inside corners up three walls and between the 3 new walls & the ceiling. We also had to form outside corners on the window frame, the pass-thru and the hallway entrance. There was also an outside corner on the concrete beam above the brick wall, but that repair will be part of another post. 

some materials used

outside corners on window are in, inside corners on wall/ceiling need to be done, a gap at top of wall was pre-filled

The outside corners were the easier of the two. We used plastic corner beads that are stapled onto the dry and smoothed over with the joint compound. The toughest part of that was cutting and mitering the corners so that all the openings were square.

On the inside corners we used paper tape reinforced with metal strips. To install it you need to measure out a piece the proper length, spread out a layer of joint compound over each side of the corner (being sure not to put it on too thick, except in areas where the seams are really out of square). You then fold the tape down the center & place the tape into the corner keeping it as square & level as possible. Use the trowel to press it smoothly down into your layer of joint compound and then add another layer of joint compound over the top to bed it in securely. The toughest one of those joints was the 14’ long joint on the ceiling, there was a substantial amount of space (almost an inch) in the middle of the ceiling that needed to be filed in. Luckily my husband & I were able to work on that together and he devised way to project a line along the wall for us to follow to keep the tape level across the length of the wall. Once the joint is dry, and then comes the hard part of leveling out the dips in the walls and ceiling to meet your nice new sharp corners. It took quite a few passes on the ceiling to fill in that valley, especially a pain when having to go up & down the ladder so many times.
