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.
You can find more information on our web, so please take a look.
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.
This may differ from product to product, though the majority of Trim-Tex corner beads are installed by applying two coats of 847 Spray Adhesive (one to the bead and one to the drywall, or two coats to either), pressing the bead into place and applying half-inch staples every six to eight inches along the bead’s mud legs. If you do not use the recommended 847 Spray Adhesives, apply staples every two to three inches. Fast Edge® and Mud Set corner beads are installed using only joint compound, either by running the bead through a hopper or applying mud directly to the drywall.
For installation guidelines for individual products, you can find detailed instructions on each product’s page on Trim-Tex.com, or by searching for the product on our “Resources” page.
