Rip-Bead® L-Bead

Creates a clean line at intersection of gypsum board and ceiling grid

Rip-Bead® L-Bead is designed to cover the raw edges of drywall at ceilings, windows and other finished interior components.

Description

Features a 1/4" removable leg that acts as a guide for the taping knife and a protective mask for the application of joint compound.

  • Eliminates clean up and masking tape.
  • Rust proof and dent resistant.
  • Multiple perforations enhance joint compound adhesion.
  • Produces clean, finished edges at panel terminations.

 

Installation

Step 1:
When installing the drywall, allow for a 1/8” gap between the drywall and the adjacent interior surface to accept the leg of the Rip Bead L-Bead to ensure a straight, flat application. Avoid using the tapered edge of the drywall board for this application. Make sure the surface of the drywall is clean and smooth. Measure and cut the L-Bead to length, subtract ½” for vertical applications. Dry fit the Rip Bead L-Bead to ensure the optimum fit. 

Step 2:
For optimal results spray the drywall surface and the flanges of the L-Bead with spray adhesive and position the Rip Bead L-Bead into place. Once in position, apply pressure with the handle of your taping knife and then staple the corner bead every 6” – 8” with ½” staples to keep the L-Bead tight to the drywall surface. 

Step 3:
Using a 6” taping knife, apply the first coat of joint compound to the surface of the Rip Bead L-Bead. The use lightweight 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.

Step 4:
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 5:
Gently remove the Rip Bead removable leg after the final coat of compound is completely dry and before sanding.

Step 6:
Sand lightly with 120 grit sandpaper to finish.
