Once the drywall is installed, it needs the protection that a drywall corner bead is designed to give. Over time, the drywalls will be subjected to moisture and external pressures and the drywall edges at the corners are the first to experience that. You have to spend a little more money and install corner beads just to protect these vulnerable parts.
Drywall Corner Bead Types
The most common corner bead type that we can see is the L-shaped type. I know of other types such as the ones with L-shape also but with accompanying tape. Other types are bullnose, bullnose archway, L-shaped archway and the ones that they use and install from the inside part of the corner attachment.
The bullnose type, which can be bought in 8 to 10 feet of length, has a rounded edge. That type is smoother and easy to conceal than the L-shaped types. Curved corners and archways should be covered with the archway types of corner beads. These archway types are also good to use if the lumber is the kind that easily twists or warps.
The inside corner beads are additions that you can use for a more sturdy and well-protected attachment. As the name suggests, an inside corner bead is attached opposite the side where regular beads are attached.
Corner Bead Drywall Accessories – When To Install
As soon as the drywalls have been hung and before taping the joints, immediately install the corner beads. Once the beads have been placed, cover the spot with drywall compound and sand to smoothen the area.
Choose Matched Sizes
When choosing and installing the beads, you will have to match the size of the beads with the size of the drywalls. If there are corner beads that exactly match the size of the drywalls, you will be spared from the necessity of cutting the beads before installing. And if there are no exact matches, you will be forced to buy corner beads that are long and throw away the extra.
What Properties To Look For When Choosing The Brand
As I said, if you use drywall inside corner bead in addition to the exterior bead, you will have the benefit of having a more sturdy and well-protected attachment. But that can sure add up to the cost significantly. A better alternative is to buy beads that are superior in quality. Look for the following properties:
- Corrosion resistant
- If possible, buy corner beads that don’t need the use of joint compound
- Resistant to kinking, denting and blisters
- Straight, crisp and durable lines
- Rust resistant
Installing Drywall Corner Beads
After cutting the bead to the right size, place it on the corner where the drywall edges meet and then attach it using screws. Let the distance of each screw be five or six inches from the next and tighten each screw just enough to not cause warping of the bead.
Next, apply the drywall compound on the bead. Apply vigorous amount of the compound using a trowel and with the same trowel, even out the compound until a clean, smooth finish is achieved.
