Clinch-On corner bead is recognized as the premier product for providing sturdy galvanized metal reinforcement on 90˚ drywall corners. Knurled and perforated flanges offer superior compound adhesion for smooth, straight finishes. Corner bead attachments are accomplished by nailing, stapling, screwing or clinching through the flanges.
Measure the wall height and subtract ½”. Measure and cut the corner bead using aviator snips. Dry fit to ensure accuracy.
Position the bead on the corner. Place the clinch-on tool over the bead.
Hit the tool with a rubber mallet to crimp the bead to the corner, repeating every 8” to 10” for optimum fastening.
Using an 8” taping knife, apply the first coat of joint compound to the surface of the corner bead. The use of lightweight or setting-type compound in this step will reduce shrinkage and speed up drying time. Let this dry completely, for several hours or overnight.
Using an 8” or 10” taping knife, apply a light finish coat of joint compound. Feather the compound beyond the previous coat. The use of all-purpose or topping compound will make for a more durable finish. Let this dry completely, for several hours or overnight.
