A cracked wall could lead to a more extensive repair if it’s not fixed at once. The best way to remedy a crack on the wall is to put a joint compound. The joint compound is a kind of putty designed to fill the cracks on concrete. The least expensive method of repairing the crack involves re-taping the horizontal seam where the wall meets the ceiling. Before applying a new drywall corner bead.

If the crack is near any woodwork or trim, cover with painters’ tape to protect the surface. Next, use the utility knife to cut a v-shape notch the entire length of the crack. Clear any debris from the cut (a shop vac could be handy). Step 2: Apply Drywall Tape. Apply 1/8 inch of joint compound over the crack and embed a strip of drywall tape.
Exterior ceiling repair-paper tape cracking and falling down
This type of problem is very common on interior and exterior drywall ceilings
.
Over time the paper drywall tape begins to crack and fall down due to the heat and humidity from our harsh Florida climate.
The extreme weather changes cause the wood framing to expand and contract on a daily basis in turn causing just enough movement of your ceiling to crack and pop the paper tape joints. Especially if the ceiling was nailed or not enough screws were added during the drywall installation process when your home was built. Due to the drywall crew trying to move to fast!
That’s why I always re-secure the drywall joints with screws and check the entire ceiling to make sure it was secured properly during the construction phase. A lot of times the ceiling needs to be completely re-screwed.
The paper tape joints were cracking and starting to fall down on this pool patios drywall ceiling in Viera.
After I removed the tape and while securing the ceiling and joints with screws. I figured out that one section of a drywall seam was sagging in an area where there was no wood framing member to attach the drywall to and had popped the paper tape from movement.
Paper tape joints removed
So I cut out a small 4″x6″ section of the ceiling and added a furring strip to span over both sides of the sagging drywall tape joint. Which I attached to the backside of the ceiling by screwing four screws into the furring strip from the finished side of the ceiling.

Then, I re-attached the same piece of drywall that I had cut out for a perfect fit.
Next, I installed the self adhesive fiberglass mesh tape and applied three coats of 20 minute Easy Sand quick setting joint compound to the exposed seam and completed the drywall finishing by skim coating the entire ceiling with USG Sheetrock all purpose joint compound (green lid).
This way when I do the skip trowel texture, it will all be one consistent texture. Instead of trying to blend the new texture from a repair into the old texture. Which sometimes can still be noticeable depending on several different factors. Such as painted surfaces absorb differently even after priming.

I then applied a skip trowel texture to the entire ceiling and let it dry for 24 hours.

Lastly. I primed the entire ceiling with quality exterior water based primer and top coated the newly skip troweled ceiling with two coats of a quality flat white water based exterior paint.
