L-Bead

Provides clean, sharp edge at wallboard terminations

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

Application(s): Drywall

Easy attachment is attained with nails, screws or staples to studs through bead flange. Multiple perforations along the 1-1/8" flange enhance strong compound adhesion and the raised shoulder provides for a flush finish. Rigid vinyl will not rust, dent resistant and easy to field cut without distorting profile or leaving sharp edges and burrs.

  • Produces finished edge at panel terminations.
  • Raised shoulder and perforations enhance compound adhesion.

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 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 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 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 L-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.

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:
Sand lightly with 120 grit sandpaper to finish.
