Installing Rounded Corner Bead for a Smooth Drywall Finish
Embracing the rounded corner look in your drywall project? Rounded corner bead not only adds a modern touch but also reduces the risk of sharp edges. Here's a comprehensive guide on how to install rounded corner bead drywall, ensuring a professional finish.
Tools and Materials Needed

Step-by-Step Installation Guide
1. Measure and Cut the Corner Bead
Start by measuring the length of the corner you'll be working on. Cut the rounded corner bead to size using a utility knife or drywall saw. Ensure the cut is straight and clean.
2. Attach the Corner Bead
Using a stud finder, locate the studs along the corner. Mark their locations with a pencil. Starting at the top, attach the corner bead to the studs using drywall screws. Space the screws about 6-8 inches apart. Ensure the bead is flush with the drywall surface.

For non-stud areas, use drywall screws with plastic anchors to secure the bead. Maintain a consistent gap between the bead and the wall, usually around 1/8 inch, to allow for compound application.
Finishing the Corner
3. Apply Joint Compound
Apply a thin layer of joint compound (mud) along the corner bead using a 6-inch drywall knife. Ensure the compound covers the screw heads and fills any gaps. Allow the compound to dry according to the manufacturer's instructions.
4. Apply Joint Tape
Once the compound is dry, apply a thin layer of mud along the corner bead. Embed a piece of joint tape into the mud, ensuring it covers the corner seam completely. Smooth the tape with the knife, removing any wrinkles or bubbles.

5. Apply a Second Coat of Compound
Apply a second coat of joint compound over the tape, feathering the edges to blend with the surrounding wall. Allow this coat to dry.
6. Sand and Finish
Once the final coat is dry, lightly sand the corner using a drywall sanding screen to remove any excess compound and create a smooth, seamless finish. Wipe away any dust with a damp cloth.
Your rounded corner bead drywall installation is now complete! This process might take some practice, so don't hesitate to ask for help or seek professional advice if needed. Happy drywalling!
