Tools and Materials Needed
Before you get started, ensure you have the following tools and materials on hand:
- Corner bead (ensure it's the right size for your doorway)

- Utility knife
- Drywall screws
- Drywall screw gun or drill
- Drywall compound (mud)
- Joint tape
- Putty knife
- Sandpaper (120-grit)
Step-by-Step Installation Guide
Measure and Cut the Corner Bead
Start by measuring the height of your doorway. Cut the corner bead to this length using a utility knife. It's a good idea to score the bead first, then snap it along the line. This will give you a clean break.

Mark the Center Line
Using a straight edge or level, draw a center line down the doorway where you'll install the corner bead. This will help you ensure the bead is centered and straight.
Install the Corner Bead
Starting at the top of the doorway, position the corner bead so that it's centered on your mark. Use a drywall screw to secure it in place. Continue down the doorway, spacing your screws about 6-8 inches apart. Ensure the bead remains centered and straight as you go.
Dealing with Obstructions
If your doorway has any obstructions, such as light switches or outlets, you may need to cut the corner bead to fit around them. Use a utility knife to score the bead, then snap it and trim it to size.

Apply Drywall Compound
Once the corner bead is installed, it's time to apply drywall compound. Using a putty knife, spread a thin layer of mud over the bead, ensuring it's completely covered. Allow this to dry.
Apply Joint Tape
After the first layer of mud has dried, apply a layer of joint tape over the corner bead. Ensure it's smooth and free of wrinkles. Apply another layer of mud over the tape, feathering it out to blend with the surrounding wall.
Sand and Prime
Once the final layer of mud has dried, use sandpaper to lightly sand the area. This will remove any rough spots and ensure a smooth finish. Wipe away any dust, then apply a coat of primer to the area. This will seal the drywall compound and prepare the surface for painting.
Tips for a Professional Finish
Here are a few tips to help you achieve a professional finish:
- Work in a well-ventilated area to avoid breathing in drywall dust.
- Wear gloves to protect your hands from drywall compound.
- Don't apply too much mud at once. It's better to apply multiple thin layers than one thick layer.
- Allow each layer of mud to dry completely before sanding or applying the next layer.
Conclusion
Installing corner bead around a doorway is a straightforward task that can significantly improve the look of your space. By following this guide and taking your time, you'll achieve a professional finish that you can be proud of. Happy DIYing!
