After you have hung the walls and ceilings you will need to install the corner bead. Make sure you put the sheetrock inside all the windows and the outlets are all cut out. Rasping the edges and corners off all the hung sheetrock will make installing easier.
There are two types that come in various lengths:
1 - Bull Nose
2 - Standard Square
There are two types of material for the two types:
1 - plastic
2 - metal
There is no difference in how to install the plastic or metal.
Measure the corners and cut the piece to fit, using Tin Snips. If you have a corner that is longer than the piece you have and need to use more than one piece per corner, do not overlap them, “butt it up". Put them as close together as possible and follow the instructions below.
Bull Nose: There are two ways to install this type.
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 your cut piece. Put it 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. Allowing to dry over night gives that added assurance that when you are mudding you know your not going to get it under the sides and won't have a fix-it project to do later because it lifted.
2 - nailing: the best to use is regular sheetrock nails at an inch and 1/8 to inch and 1/4 . Put your cut piece 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 edges do 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.
1 - gluing: same as above
2 - nailing: same as above
3 - crimping: Please note: you cannot crimp the plastic. Put your cut piece 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.
