Installing the Corner Bead

   

After you have hung the walls and ceilings you will need to apply the corner bead. Make sure you put the sheetrock inside all the windows and the outlets are cut out. Rasping the edges and corners off all the sheetrock hung will make applying the corner bead easier.

There are two types of corner bead that come in various lengths:
1 - Bull Nose
2 - Standard Square

There are two types of material for the two types of corner bead:
1 - plastic
2 - metal

There is no difference in how to install the plastic or metal corner bead.
Measure the corners and cut the corner bead to fit using Tin Snips. If you have a corner that is longer than the piece of corner bead and need to use more than one piece of corner bead per corner do not overlap them, “butt it up”. Put them as close together as possible and follow the instructions below as follows.

Bull Nose:There are two ways to install this type of corner bead.

1 – gluing: these are spray adhesives. The best one recommended is Corner Bead Spray Adhesive. Use according to manufacturer Instructions. Spray the adhesive on the entire inside of the corner bead. Put the corner bead on the corner and apply pressure in the middle working upward with one hand and downward with the other. Making sure there are no bumps or bubbles on the edges of the corner bead. Allowing to dry over night gives that added assurance that when mudding you know your not going to get it under the sides of the corner bead and won’t have a fix-it project to do later because the corner bead lifted.

2 – nailing: the best to use is regular sheetrock nails at an inch ¼. Put the corner bead on the corner and put one nail in the center of the corner bead on each side. Working upward first then downward put a nail in at about 2 inches apart. Make sure the edge of the corner bead does not lift. If its does, put a nail in where it is lifted. You can start mudding immediately afterward.

Standard Square: There are three ways to install this type of corner bead.

1 – gluing: ibidem

2 – nailing: ibidem

3 – crimping: Please note: you cannot crimp the plastic corner bead. Put the corner bead on the corner and put the crimper in the center first. Apply pressure to the crimper and hit it with the rubber mallet. This style pinches the corner bead to the corner by pinching both sides simultaneously. Work upward first then downward. Once it’s all crimped check for any lifting. If there is lifting crimp down the part(s) that are lifted. You can start mudding immediately afterward.
