How to Tape Corners on Drywall

Taping corners on drywall is a crucial step in creating a smooth and seamless wall surface. Proper corner taping techniques ensure a strong and durable bond between the drywall sheets, preventing cracks or separation. Here's a comprehensive guide to help you tape corners on drywall like a pro.

Materials You'll Need:

Drywall joint compound
Paper or mesh drywall tape
Putty knife
Joint knife
Sponge or damp cloth

Step 1: Prepare the Corners

Start by检查ing the corners to ensure they're straight and square. If necessary, use a drywall square to adjust the angles. Cut the drywall tape to the length of each corner, making sure it extends at least 6 inches beyond the corner on both sides.

Step 2: Apply Joint Compound

Using a putty knife, spread a thin layer of joint compound to one side of the corner and the center of the opposite side. The compound should be smooth and free of lumps.

Step 3: Position the Tape

Carefully place the drywall tape over the wet joint compound, centering it on the corner. Press the tape firmly into place, ensuring it's completely covered in compound.

Step 4: Embed the Tape

Using a joint knife, gently press down on the tape to embed it into the joint compound. Apply more compound over the tape, embedding it completely. Smooth the compound with long, even strokes.

Step 5: Feather the Edges

Once the first coat has dried, apply a wider coat of joint compound over the tape and extend it at least 6 inches beyond the edges. Use the joint knife to feather the edges, creating a smooth transition between the drywall and the compound.

Step 6: Sand the Tape

When the second coat is completely dry, lightly sand the tape and surrounding area using a fine-grit sandpaper. Sanding will remove any rough spots or unevenness.

Step 7: Apply a Third Coat

Apply a third and final coat of joint compound, extending it even further beyond the edges. Feather the edges again to create a seamless finish. Allow the third coat to dry thoroughly.

Step 8: Prime and Paint

Once the taped corners have dried completely, apply a coat of primer to seal and help the paint adhere better. Allow the primer to dry before applying your final coat of paint.

Tips:

Use paper tape for inside corners and mesh tape for outside corners.
Apply joint compound in thin coats and allow each coat to dry completely before applying the next.
Use a damp sponge or cloth to clean your tools as you go.
Practice on scrap pieces of drywall before working on the actual wall.

By following these steps and tips, you can easily tape corners on drywall, ensuring a strong and flawless finish for your walls.
