Highlights:

Step 1: Remove Old Drywall Patches and Tape

Make sure your workspace is covered with a drop cloth. Remove any old drywall tape or patches with the scrapper. To remove drywall tape, use the 5-in-1 tool to get underneath the lip of the tape and begin to take the whole strip off.

Step 2: Attach Screws to Attic Blocks

Drill some drywall screws into the ceiling. These screws will attach to the wooden support blocks which were installed in the attic above in the first step of this project.

Step 3: Widen the Ceiling Crack

Next, take the scrapper (5-in-1) tool and rip a gouge in the ceiling just to make the crack a bit wider. This will give the joint compound something to adhere to.

Step 4: Apply Drywall Tape and Mud

Apply a single strip of drywall tape to the crack. Then, apply the first layer of joint compound making sure to push the mud through the mesh of the tape and into the crack.

Step 5: Smooth the Surface

Once you've got the first layer on, go over it with a damp double-sided sponge. Use the rough side to smooth out any lumps, then go back over with the smooth side to finish it.
