The benefit of using drywall is that the home renovation task is easier compared to using concrete or bricks, but there are times when installing drywall can be a bit challenging, especially in the corners. In fact, drywall corners that are off angle are the most challenging task when applying drywalls. An off-angle corner has an angle that is either greater than or less than 90 degrees. Thus, if you happen to encounter this particular problem while installing drywall, here is a quick DIY remedy that will help you install drywall on off-angle outside corners of your walls.

Step 1 - Tape the Corner of Your Wall

Use an adhesive and tape the corner of the drywall. Start applying the joint compound from an inside corner and work your way outside. Measure the length of the entire corner and cut the tape to the particular length of the drywall corner. Fold the tape lengthwise and fit it to the creases on the corner. Press the tape firmly to hold the drywall later.

Step 2 - Spread the Joint Compound on the Corner

Using an applicator brush, soak the bristles in a can of joint compound. Apply the joint compound from the corner and work your way out. Make sure that you have applied the joint compound four inches out from the corner of the wall. A joint compound is a substance that is similar to plaster and is used to seal joints between two sheets of drywall. Let the joint compound dry for a few hours, depending on the instructions of the manufacturer.

Step 3 - Feather and Sand the Joint Compound

Once dry, use a fine brush to clean the joint compound properly. Also use a 120-grit sandpaper to sand the joint compound until smooth. Wipe the dust using a clean cloth and remove the finer particulars using a fine brush. Apply the second coat of the joint compound, let it dry and sand it again.

Step 4 - Apply the Metal Bead

Using a tape measure, cut a length of the metal corner bead to fit the outside corner. Apply the metal bead to the corner and secure it by driving screws along its entire length. To facilitate the application of the screw, use a drill every five inches through the metal bead and drive a screw for each hole that was drilled on the metal.

Step 5 - Hide the Metal Bead and Apply the Finishing Touches on the Drywall Corners

Once the metal bead is held firmly in place, spread a joint compound over it and let it dry. Once dry, sand the joint compound until it becomes smooth. Apply the second coat, let it dry then sand it again. You are ready to paint the drywall with the desired color that you want.
