Step-by-Step Guide- How to Professionally Install Plastic Corner Bead on Drywall

How to Install Plastic Corner Bead on Drywall

Installing plastic corner bead on drywall is a crucial step in achieving a professional finish to your interior walls. Corner bead serves as a protective barrier for the corners of your walls, preventing them from cracking or chipping over time. This article will guide you through the process of installing plastic corner bead on drywall, ensuring a smooth and durable finish.

Materials Needed

Before you begin, gather the following materials:

– Plastic corner bead
– Drywall compound
– Drywall tape
– Putty knife
– Sandpaper
– Primer
– Paint

Step 1: Prepare the Wall

Start by cleaning the wall where the corner bead will be installed. Remove any dust, dirt, or debris to ensure a clean surface. If there are any cracks or holes in the drywall, fill them with drywall compound and allow it to dry completely.

Step 2: Measure and Cut the Corner Bead

Measure the length of the corner where you will be installing the bead. Use a utility knife to cut the corner bead to the desired length. Ensure that the cut is straight and clean to prevent any gaps or uneven edges.

Step 3: Apply Drywall Tape

Apply drywall tape to the corners of the wall. The tape should be applied in a straight line, covering the entire length of the corner. Press the tape firmly into place, ensuring that it adheres well to the drywall.

Step 4: Apply Drywall Compound

Using a putty knife, apply a thin layer of drywall compound over the drywall tape. The compound should be applied evenly, covering the tape completely. Allow the compound to dry for a few hours or overnight, depending on the thickness of the layer.

Step 5: Install the Corner Bead

Position the plastic corner bead against the corner of the wall, ensuring that it is flush with the edges of the drywall. Use a putty knife to press the bead into the compound, making sure it adheres well to the wall. Repeat this process for each corner where you will be installing the bead.

Step 6: Apply Additional Drywall Compound

Once the corner bead is in place, apply another layer of drywall compound over the bead. This layer should be slightly thicker than the previous one. Allow it to dry completely.

Step 7: Sand and Prime the Wall

After the compound has dried, use sandpaper to smooth out any rough edges or high spots. Once the wall is smooth, apply a coat of primer to the corners. This will help the paint adhere better and provide additional protection against moisture.

Step 8: Paint the Wall

Finally, paint the wall with your chosen color. Apply a coat of paint, ensuring even coverage. Allow the paint to dry completely before moving on to the next project.

By following these steps, you can successfully install plastic corner bead on drywall, achieving a professional and durable finish.
