Drywall is a popular and affordable material used for walls and ceilings in modern construction. However, even with careful installation, drywall is prone to cracking and damage, particularly in corners where two walls meet. One effective method for repairing a cracked corner in drywall is to use flexible corner tape. In this article, we will discuss how to use flexible corner tape to repair a cracked corner in drywall.

Step 1: Prepare the area

Before beginning the repair process, it’s important to prepare the area around the cracked corner. First, remove any loose or damaged drywall from the area. Next, sand the surface of the wall around the crack to create a rough surface for the joint compound to adhere to. Finally, clean the area with a damp cloth to remove any dust or debris.

Step 2: Cut the flexible corner tape to size

Flexible corner tape is available in different widths, so measure the width of the corner and cut the tape to the appropriate size. Be sure to cut the tape long enough to cover the entire crack, with a few inches of extra tape on either side of the corner.

Step 3: Apply joint compound

Using a putty knife or trowel, apply a thin layer of joint compound to the area where the tape will be applied. Make sure the joint compound covers the area completely, with a little bit of excess around the edges.

Step 4: Apply the flexible corner tape

Carefully apply the flexible corner tape to the area, making sure that it is centered over the crack. Smooth out any wrinkles or air bubbles in the tape by using a putty knife or trowel to press the tape firmly into the joint compound. Make sure the tape is flush against both walls and the ceiling.

Step 5: Apply a second layer of joint compound

After the tape is applied and smoothed out, apply a second layer of joint compound over the tape. Use the putty knife or trowel to spread the joint compound evenly, making sure to cover the entire tape. Let the joint compound dry completely, following the manufacturer’s instructions.

Step 6: Sand and paint

Once the joint compound is completely dry, sand the surface smooth with a sanding block or sandpaper. Be sure to sand the area gently to avoid damaging the tape. After sanding, wipe the area with a damp cloth to remove any dust or debris. Then use PVA drywall primer to prime the freshly sanded drywall. Finally, paint the area to match the surrounding walls and ceiling.

In conclusion, repairing a cracked corner in drywall using flexible corner tape is a simple and effective solution. By following these steps, you can easily repair cracks and damage in your drywall, ensuring that it remains in good condition for years to come.
