Step 1:
Make sure the surface of the drywall is clean and smooth. Avoid using the tapered edge for this application. Measure and cut the Rip Bead Muddable J-Bead to length subtract ½” for vertical applications. Dry fit the Rip Bead J-Bead to ensure the optimum fit.
Step 2:
Position the mud leg of the Rip Bead Muddable J-Bead so that it is facing the room’s interior. Slip the J-Bead over the edge of the drywall until both edges meet.
Step 3:
Install the drywall equipped with the J-Bead using screws as normal.
Step 4:
Staple the Rip Bead Muddable J-Bead every 6”– 8” with ½” staples while applying pressure by hand to keep the J-Bead tight to the drywall surface.
Step 5:
Using a 6” taping knife, apply the first coat of joint compound to the surface of the Rip Bead J-Bead. The use lightweight compound or setting-type compound in this step will reduce shrinkage and speed up drying time. Let this dry completely, for several hours or overnight.
Step 6:
Using an 8” 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.
Step 7:
Gently remove the Rip Bead removable leg after the final coat of compound is completely dry and before sanding.
Step 8:
Sand lightly with 120 grit sandpaper to finish.
