How to Replace Inside Corner Drywall Tape

Damaged inside corner drywall tape can lead to cracking, peeling paint, and other unsightly blemishes. Repairing it promptly is essential to maintain the integrity of your drywall. Here's a step-by-step guide to help you tackle this task like a pro:

Materials You'll Need:

Inside corner drywall tape
Joint compound
Putty knife
Sandpaper
Damp sponge

Step 1: Remove the Damaged Tape

Using a utility knife, carefully score along the edges of the damaged tape to loosen it. Remove it gently, being cautious not to tear the drywall paper.

Step 2: Clean the Area

Wipe down the exposed drywall area with a damp sponge to remove any dust or debris. Let it dry completely.

Step 3: Apply Joint Compound

Apply a thin layer of joint compound to the recessed area using a putty knife. Ensure that the compound extends slightly beyond the edges of the tape.

Step 4: Embed the New Tape

Cut a piece of inside corner drywall tape to the length required. Press it firmly into the wet joint compound, ensuring it is centered in the corner.

Step 5: Apply More Joint Compound

Spread another layer of joint compound over the tape, overlapping it by about 2 inches on each side. Smooth out the compound with the putty knife.

Step 6: Let it Dry

Allow the joint compound to dry completely according to the manufacturer's instructions. This may take several hours or even overnight.

Step 7: Sand and Finish

Once the joint compound is dry, lightly sand it with fine-grit sandpaper to remove any bumps or imperfections. Wipe away the dust, and you're all set!

Tips:

Use a slightly damp sponge to smooth out the joint compound, as it helps prevent cracking.
Apply thin layers of joint compound to avoid shrinkage and cracking.
If the damage is extensive, you may need to use drywall mesh tape for added reinforcement.

By following these steps, you can effectively replace inside corner drywall tape and restore your walls to their pristine condition. Remember, patience and attention to detail are key for a professional-looking finish.
