In this video we will show you how to Repair a Cracked Drywall Ceiling. There are many reasons causing Cracked Drywall Ceiling such as: Improper taping joints, Damage from above, Water damage, Structural damage…
"Damage From Above" is one of the most common reasons that causes Cracked Ceilings. Ceilings aren't just the room-facing part that you see most of the time. Ceilings have a top side, as well. Up in the attic, the ceiling is usually unprotected. With just loose-fill or fiberglass insulation over the drywall, the drywall is prone to damage from anyone who moves around or anything heavy that drops.

3:22 screw the wal board to the strap
3:34 run some construction adhesive on the top of the wall board
3:48 lay a plywood in push it around a little bit
4:38 put a couple of screws on each side of the crack
4:56 bang the jack out
5:13 use hammer to knock off any loose pieces
5:23 use the painter's tape to protect the wall a little bit
5:29 use the fiberglass mesh tape to tape over the crack
5:38 ready to cover over the patch with some joint compound
5:48 take the compound and skim over the tape and the cracks lightly
6:36 the patch almost done, need a couple of days to dry then put a coat of paint

So you blaming your kids for this? Absolutely. First I thought I might be able to tape it up
and just re-plaster it and be done deal but then I thought maybe I had to cut a rectangle around
put some more drywall up. At that point I just figured that was over my head. Well you're right
about one thing. It's a ceiling so it is over your head. Come on let's take a look up in the attic.
And here's what happened. I climbed up the attic stairs trying to go get the toy. What I usually
try to do is put my feet on the plywood and when the plywood runs out I'll put my hands on these
collar ties here and put my feet on the joist. Yeah. I walked back and got the toy and I heard
my kids scream and I said oh I better hurry. So I started going back a little too fast and I noticed
right here when I put my foot down I didn't hit the joist. You missed. I missed. All right so let's
see. Take out this insulation. Oh yeah there's the damaged wall board right there. Let me see
this one. Yeah you can really see the damage. Well what you have here first of all
this is a two by eight ceiling joist and they're 16 inches on center and they run from the front
of the house to the back of the house or rafter to raft. Underneath that is this one by three
furring strip or strapping. What's this used for? Well it's a couple of things. The electrician can
use it to run their wires under the joist so they don't have to drill them and the wall board is
fasten their wall board to it. So we're going to have to cut out the damaged wall board and replace
it. No we're going to re-secure the damaged wall board. All right what I want to do is I want to
locate the strapping from down below. To do that I'm simply going to drill a hole in the middle of
the strapping right through the ceiling. Now I can see that hole from down below. All right let's
see if we can see that hole. There it is. Now that hole is our first piece of strapping and we know
that it runs across the room this way. Every 16 inches across the ceiling is another piece of
strapping. Now what I've done is I've taken two pieces of plywood and I screwed it together
because I want it to be really rigid. What's with the holes? It almost looks like a piece of Swiss
cheese. Well this row of holes right here represents the strapping above. This row of
holes is 16 inches apart from this row hole represents the second piece of strapping. Now
what I want you to do is hold this up under the ceiling but line up one of the holes with that
hole. All right now what I've did is I actually cut a piece of two by four to fit between the
ceiling and the floor and I'm going to use this to jack up that piece of plywood pushing the wall
board up against the strap. Now I have another piece of plywood on the floor so I don't damage
the floor. Okay I've installed a drywall tip in my screw gun which will allow the drywall screw
to countersink just at the right depth. I'm going to screw it right through one of the holes.
All right now we've screwed the wall board to the strap. Now we have to introduce some structure
between the strapping so we can screw the wall board to it. I'm simply going to use a piece of
five-eighths plywood. Before I put the plywood in I'm going to run some construction adhesive
on the top of the wall.
Now the plywood fits under the joist loosely because it's a little bit thinner than the strap.
One there. Okay a little over here.
Take the next piece.
Now a couple of shims under the joist. I'm going to sandwich it between the plywood
joist pushing the plywood down tight to the wall board.
Now that's it just screw off the middle. Okay you got them all? Yep. All right let's put a
couple of screws on here on each side of this crack and that side of that crack. Okay.
All right Kevin you want to hold that plywood. I'm going to bang the jack out. Ready? Yep.
Let's see how it looks. Ah pretty good. We got some touch-up to do.
Now using my hammer I'm going to knock off any loose pieces. Then we'll be ready for joint
compound. Using this painter's tape will protect the wall a little bit.
Now I want to use this fiberglass mesh tape to tape over the crack.
All right now we're ready to cover over our patch with some joint compound.
If we look at the pattern that's on the ceiling it's actually called a skip
trowel pattern. So the first thing I want to do is I want to take my compound
and I want to skim over the tape and the cracks lightly.
Nice layer right over it. With the cracks and the screw heads covered we're ready to apply the
To do that I'm simply going to lay a little compound on my trowel and I'm gonna skip right
over the ceiling. The reason we call it skip troweling is because I'm not applying a lot
of pressure. The trowel is actually skipping over. Well what do you think Kevin? This is great. I
Now in a couple of days when it's dry put a coat of paint on it and it should disappear.
You think you can handle that? Definitely.
