Today I’m going to show you how to cut back
the paper backing. As you can see with a side view of the sheet rock, you have to take off
this layer of backing on both the placement piece that you’re going to inset in the
wall and what exists on the wall itself.
And what you want to do is go back, probably,
about an inch and a half on each side of the hole. Just with a box cutter, make a few cuts.
You’ll be able to tell when you cut through the paper. And you just get a putty knife,
insert it between the sheet rock and the paper, and it should just peel right off, just like
that. And make sure that you get at least half of the paper off. And it doesn’t have to be square, because
you’re going to tape a float over it.
And once you get all done, make sure you get
all the little loose ends off. And you’ve got to do the same thing on the little patch
part that you’ve already measured and cut that will inset just like that. Actually,
on this one, you’re not going to have it because it’s going to inset some to where
there’s a lip. But you should do the same on the inside piece, too.
