How to Install L Metal Corner Bead

Installing L metal corner beads is an essential step in achieving a professional finish for drywall corners. This product provides a strong, durable edge that protects the drywall from damage while creating smooth seams. Follow these steps to install L metal corner bead successfully.

1. Gather Your Tools and Materials
   Before you begin, ensure you have the following tools and materials:
   • L metal corner bead
   • Drywall screws
   • Drywall knife
   • Construction adhesive
   • Pearl-tipped or finishing nails (optional)
   • Measuring tape
   • Level
   • Screw gun
   • Stapler (if necessary)
2. Measure and Cut the Corner Bead
   Use your measuring tape to measure the length of the corners where you intend to install the L metal corner bead. Mark the measurements on the bead. Using a tin snips or a metal cutter, carefully cut the bead to size. Ensure the edges are straight and even for the best fit.
3. Prepare the Wall Surface
   Before installation, ensure that the wall surface is clean and free of debris. If there are any rough spots or protruding nails, sand them down to create a smooth surface for the corner bead.
4. Apply Adhesive or attach directly
   For added stability, apply a small bead of construction adhesive along the wall edge where the corner bead will be installed. If you choose not to use adhesive, you can attach the corner bead directly to the drywall using drywall screws or nails.
5. Position the Corner Bead
   Begin positioning the L metal corner bead at the top of the wall corner. Hold it in place and ensure that it is aligned straight using a level. Push the bead firmly into the adhesive if you applied it. If you’re attaching the bead with screws, use your screw gun to secure it to the wall, placing screws about every 12 inches apart.
6. Secure the Bead
   If you opted for nails, use the stapler or finish nails to secure the corner bead at regular intervals. Make sure that the bead is flush against the wall for a seamless appearance without gaps.
7. Apply Joint Compound
   After the corner bead is installed, apply a coat of joint compound over the corner bead with your drywall knife, feathering it out onto the surrounding drywall. Allow it to dry completely, then sand it down until smooth.
8. Finish the Surface
   After the joint compound has dried, you may need to apply a second coat and sand again for an ultra-smooth finish. Once you are satisfied with the surface, prime and paint as desired.

By following these steps, you can install L metal corner beads effectively and ensure that your drywall corners are both aesthetically pleasing and durable.
