When installing the drywall, use the full drywall setback on the PRO Splayed Corner Bead to ensure proper fit and to achieve maximum adhesion. Avoid using the tapered edge of the drywall board on outside corners. Make sure the surfaces of the corner are clean and smooth. Measure and cut the PRO Splayed Corner Bead to length, subtract ½’ for vertical applications. Dry fit the corner bead to ensure the optimum fit.
For optimal results spray the drywall surface and the flanges of the PRO Splayed Corner Bead with spray adhesive and position the corner bead into place. Once in position, apply pressure with handle of your taping knife and then staple the corner bead every 6”– 8” with ½” staples to keep the PRO Splayed Corner Bead to the drywall surface and to ensure a solid bond.
Using an 8” taping knife, apply the first coat of joint compound to the surface of the PRO Splayed Corner Bead. The use lightweight compound or setting-type compound in this step will reduce shrinkage and speed up the drying time. Let this dry completely, for several hours or overnight.
Using a 10” taping knife, apply the final coat of joint compound. Feather the compound beyond the previous coat. The use of all-purpose compound or topping compound will make for a more durable finish. Let this dry completely, for several hours or overnight.
Lightly sand with 120 grit sandpaper to finish.
