I'm going to stick this in here and do a couple things: I'm going to attach it to this piece of framing here, and I'm going to try to attach this this duct to it as well. Okay, I'm going to cut this to, say, 14-1/2 inches.

But that's good because it'll reinforce everything. So what I'm going to have to do is … glue the lath to the back of this plaster to hold it in place.

Unfortunately, when they cut the lath off to put this duct in, they cut it off at the stud, so there's really no way to attach it here. Let's measure up and see what we can do for wood lath in here. I'm going to pre-drill this one so it doesn't split the lath any further. Then we need to stabilize all the plaster around here, and glue that right back to where it was.įirst thing we want to do is to reattach these two pieces of wood. We need to tie this lath down, put another piece of lath in behind here and glue this plaster to it. Reattaching the Lathįirst thing we do is we want to take the grate off so we can see what we have to do to repair this. There are easy ways to do this and hard ways to do this this has been done the hard way, but we can fix it. Today what we're going to do is we're going to repair what happens when you put a duct through a plaster wall and you don't pay attention to the way it's built.

Poking holes in plaster walls can leave bare lath flapping and loosens the plaster surrounding the opening.
